In Australia heat pumps (usually referred to as reverse cycle Air Conditioners) are common. Water heat pumps are also rapidly increasing. The good thing about Tesla is that the thought of the competition should drive the existing manufacturers to really up their R&D. Seems to me there would be significant advantages to combine hot water systems, home heating and cooling into one integrated product.
I worked with heat pumps here in the US (New York) back in 1980s. I'm not sure why the narrator thinks they have only been in common use for ten years. There are useful, but not a magic solution, their efficiency varies with ambient temperature.
rovert821 I think Steibel Eltron have a combi system doing both space heating and hot water. However they utilise R134a, so not a fan. Here in Australia, the best HWS heat pumps are Reclaim Energy, as are most efficient, refrigerant is CO2 & has a timer to utilise home solar PV when available. So a super effective & cheap to run system.
Here in Ukraine we have such solutions. They install a heat accumulator (a large insulated tank of water 2-3 cubic meters in size), which is heated by any heat producer installed in the house (heat pump, solar water heater, gas heater, fireplace, etc). And there are energy consumers (heated floors/walls, hot water, etc.) which consume the energy from the accumulator via heat exchangers
Heat pump was a no brainer for me several years ago when I needed a new A/C unit anyway. Propane prices had been spiking and getting pretty ridiculous, so the heat pump gave me amazing savings. It paid for itself in 3 years.
local propane companies around here (California Sierra Nevadas) say propane is going up 53% so I did the same 4/5 ton heat pump for heating and a/c. Way cheaper.
Just as an addendum, my own experience with switching from a gas HVAC to a heat pump system was more beneficial than anticipated. My previous newer home had a natural gas (utility provided not a LP tank on site) system and was a single story ranch on a slab around 1500 ft sq. My new to me 2 story home w/ a walkout has a heat pump system and is about 3200 ft sq. Both homes were built within a few years of each other. My utility bill is the same for my current house as it was for the ranch! It is actually cheaper in the cooling season, but about 15% higher in the heating season. The overall average though is the same! I was able to further reduce my bill up to 20% by improving insulation around the house for less than $1k investment. I had used the same methods in my last home for a reduction of about 10%. Bigger bang for the buck with the heat pump system.
No one uses your units of "Ft" which were fine hundreds of years ago but for 95% of the world are OBSOLETE. Go to Uganda or Malta or China and catch up with new technology where they would never ever think of building huts to live in as it is seen Americans in the north part of that continent do. Huts are banned for living in, in Europe as we don't like to see what we own blow away when there is a strong wind. And if you start with TIME then you could actually in 50 years catch up with science around the world, instead of this nonsense 10/11/12 distraction when 2012 10 11 23:23 is PRECISE and understood by EVERYONE around the world except for Americans who live in the north. Buildings last thousands of years if made properly, homes in USA last a few years before they rot or get blown into the desert. Americans really are amusing people. 2022 10 28 15 08
You need to give actual numbers. Like how many KWH did you use in each house, How many heating days in your new house vs your old house. Heat pumps are not magic and electric is expensive. Electric is about 5 times more costly than Natural gas. Every video I watch about how great heat pumps are fail to give apples to apples comparisons.
I put a 13 kw solar system on my 1800 sq. ft rambler in 2015, replaced my oil furnance with a heat pump, and in 2018 bought a Tesla M3. My total energy costs went from over $5,000 a year to about $500. The only gas I buy is for my wife's Honda Civic and my lawn mower. The heat pump uses the same heating ducts as my oil furnace did. The system works great, is quiet, and now provides AC in the Seattle area where I never thought I would need it. Thanks to Net Meeting, I bank excess solar power in the long summer days for use through most of the winter. Last year I had to pay about $50 for electricity for two months that were over the minimum $7.95 monthly charge. We did spend a lot of money on better insulation and weather stripping as our house was built in the 60's when oil was cheap.
NEVER heat or cool if you have 100% insulation. This is of course illegal in USA since the idiots must be made to pay all their lives just to stay alive. Humans (or yanks) are the ONLY creatures who are not capable of surviving in nature. Think about that. All animals and plants are naturally surviving yet those brainy humans have not figured out how to copy the birds! Well 99% are still confused and just don't know. Buying a lot of crap instead of using their common sense.
In Minnesota, my heat pump system has worked wonderfully for over 10 years. It reverts to natural gas in extremely cold weather automatically. We also enjoy high solar gain from windows and the HVAC system adjusts the fan speed to distribute that heat evenly throughout the house.
We have used Geothermal heat pumps at our home for 30 years in Michigan. Wonderful technology. In summer it also makes free hot water from the heat extracted from our home. While our unit has backup electric resistance heaters, they have never been used. We also have many south facing windows which enable the house to pass 80 degrees on a sunny winter day even with temps near zero. The heat pump fan circulates this heat through the home.
the military has been using heat pumps for yearswith "emergency heaters" that get used to death in arctic conditions. The heating coils are exactly what you find in cheap 20$ portable heaters. The heat pump works better when trying to cool things dowm but is most eficient when you have a LOT of heat on one side or the other. In a desert there can be a cooling problem instead of a heating problem because the freon never condenses enough. We ended up having to adjust the presures in the systems to get enough cooling.
With recent heat waves here in the Pacific Northwest, we're exploring a retrofit whereby our very efficient gas-powered heater is replaced by a heat pump. Our system is a bit more complex than a typical forced air system because it heats water which is then pumped sequentially through 5 different radiant floor loops. By replacing the heating system with a heat pump it is hoped that warm water in the winter will be cooled in the summer. It is worth mentioning that the current heating system doesn't need to heat the water very much: water exiting the system into the loops runs about 85°, returning to the system only a few degrees cooler. So, we expect that, in the summer, water might only be need to be cooled to, say, 65° to achieve sufficient cooling to keep the house at a comfortable temperature. It's early days, but I'm hopeful.
You cannot cool the floors, usually, as that will lead to condensation and moisture problems. But if u only got ceramic floors or you dry the air in other ways, then maybe. In Sweden coolers are air based.
Cooled floors are a bit of a nightmare. They usually don't work very well unless there's a lot of direct solar incidence on the floor that re-radiates and generates a cooling load. Otherwise yiu just end up with cold feet and a condensation risk that needs careful control.
Your heat pump will require twice the "fossil fuel" to warm your home than your inexpensive gas heater uses. For cooling, fans, trees & an inexpensive swamp cooler in your attic space would save time, $ & effort.
Screw all that... Just do mini split and save the hassle. You can get up to a 5 head unit and have custom heating controls for individual rooms. You can even get cassette air handlers that hide in your ceiling and it looks just like a vent and nothing else.
in the mid '80s I sold a wide variety of heat pumps to the residential market. Living in Canada, I was often asked how a heat pump gets heat from cold air. I would ask the client and then quickly answer.. what is the difference between 10C and -10C? 20 degrees of heat! The heat pump extracts the heat from outside and moves it inside. The biggest difference for most people is the temp coming out of the register in the house. An oil furnace or gas furnace delivers 110F and is very warm to touch. A heat pump delivers air at the register about 90F - problem is the body is at 98F, so it feels cool to the body. Put your hand over the register, a gas/oil feels warm, and a heat pump at 90F against a 98F hand feels cool. Common question: How can that heat my home?? A house is usually 70F - the heat pump even at 90F is delivering 20F of heat. In the room it feels the same 70F. Modern heat pumps are getting efficient - a significant saving in most of Canada at 30%
Great video I installed a mini split system four years ago and I’ve been very pleased I hardly ever turn on my gas furnace just use the heat pump to heat individual rooms. My system is considered a mini split. Which means one unit in each room. Disadvantage is air circulation small fans don’t push the air down the hallway necessarily. Extreme conditions I sometimes use a box fan to push the cool air around. I have a solar system from Tesla electric car model three and a small Jacuzzi (electric powered). My electric bill is still under $75 a month on average.
I’m in the HVAC field, what you are talking about is already been in practice for decades in the states. What he did in the Tesla is remarkable, taking commercial HVAC technology and put it in a car. Mitsubishi has taken it to the next level, heating and cooling from the same heat pump at the same time. It’s called VRF Technology. Now available for residential applications.
Also your refrigerant cycle chart is oriented wrong as the high pressure vapor from the compressor is fed into the top of the condenser. And high pressure liquid comes from the bottom to head the metering device just before the evaporator.
The key to a heat pump working to cool your house is the refrigerant is compressed and heated up so that it is hotter than the outside air. The outside air the cools off the hot refrigerant so when it decompresses after the expansion valve it is now cooler than your indoor air. The opposite is true as well when it is run in reverse to heat your home. It has to cool the liquid to be colder than the outside air warms the refrigerant before being compressed to make it even hotter than your indoor air. The limitations are if it is too hot outside, the compressed refrigerant is at the same temp or cooler than the outside air and stops working. In reverse it can't cool the refrigerant below the temp of the outside air and stops working.
@@kennethkeen1234 There is a reason heating oil and natural gas furnaces are used in very cold climates. They are more efficient. There is a reason evaporative cooling is used in extremely hot and dry climates. They are more efficient.
In my 2100 sq ft. ICF (Insulated Concrete Form) home here in South Alabama it cost $130 to cool my home, I use a wood stove during the "winter" weeks. I spray foamed the attic and keep a chocolate Easter Bunny in the attic for a gag sitting on top of the attic HVAC unit, he has been sitting there for several years and looks great.

In 1982 I purchased a house built in 1850 and had a long wood/oil furnace that gobbled up 2 cords (at a cost of $100) of wood the first winter in Minnesota. Before the onslaught of winter the following year I installed 20 KW of resistance heating in the duct work on the dual fuel program by the local rural electric utility. My heating bill went up to about $250 a month. The following year I purchased a used 3 ton heat pump, replaced the compressor, had outside help of an electrician and HVAC guy and my monthly bill dropped to less than $150. Go with the HEAT PUMPS ! ! !
You probably have the oldest house in USA - I have a modern house - 18th century and my neighbours' houses are from the 14th century but don't blow away in the wind!
Not sure what is new here? I have had a heat pump system in my house for the last 25 years with hepa filters due to wife's pollen allergies. Also the current refrigerants are no longer bad for the ozone layer, there refrigerants were paused out a long time ago. Why call refrigerant Freon, it like calling every car in the world a Ford? I would be more impressed if Tesla used water vapour as a viable refrigerant. In cars. (Which is technically totally doable) Not sure what Tesla is offering in this case what is not already tried and tested rechnology. Would be interesting to read the tech data,.and hopefully they made some efficiency gains.
Is there any evidence that Tesla has any plans whatsoever to get into residential (or commercial) HVAC? I don't see the business case for it, because Tesla doesn't have any new physics to bring to the table, and existing HVAC equipment is already pretty efficient.
HVAC equipment until very recently hasn't been all that efficient. Just recently I saw that there is a 6000 BTU A/C mini split that has an EER of 19 and a SEER of 33. This was unheard of 10 years ago, let alone even 2 years ago. Best EER for a 4 ton system is like an EER of 15 but again that's a very recent innovation. HVAC industry doesn't have a lot of investment in it like the tech industry because most consumers of that industry always buy the cheapest crap so not a lot of money goes towards most efficient equipment.
As a commercial HVAC technician, God I hope not. Newer equipment, especially process cooling or critical cooling is already so damn temperamental. Look at it sideways and it breaks.
@@ssaraccoii Reason refrigerants get banned every 10 years is cause patents run out. Studies (usually funded by refrigerant manufacturers like Dupont) all of a sudden discover those refrigerants are bad for the environment. But luckily those same manufacturer funding the environmental studies have new refrigerants with patents that are supposedly better for the environment ready to go. It's all a scam.
0:50 "...goes to controlling the temperature of our air...": And that is foolish. I never turn on the heat above 50 degrees. And I never turn on the A/C below 90 degrees. That's a 40 degree spread using no energy at all. And I'm always comfortable. You see, your body adapts and your comfort zone expands dramatically...and your health improves. Try it.
2:05 "...but they've really only been becoming common in the last 10 years or so...": Unless you're in the motel business. There they've been common for over 50 years.
I have both a gas furnace and a heat pump. It's all set up automatically to use the heat pump while above -20C. Although when it gets down to -40C that's when I appreciate the gas furnace.
@@manikdesign I had a professional HVAC company come in and install the heat pump and they put the heat/cooling exchanger on after the furnace blower. Saves a bunch on fuel. I only use fuel on the days that it goes below -20C.
@@routtookc8064My configuration is a 1KW grid tie and it does offset the cost of the heat pump costs, but I do know people that have a 3KW off grid system (Solar + Battery) that works for them.
My 1500sqf ranch home, near Seattle, was built in 1969. All electric with baseboard heat. The winter power bills averaged about $350 per month! Some winters even more. No A/C. About five years ago, I installed a gee-whiz mini-split two zone variable speed inverter heat pump. Energy efficient refrigerator, cloths washer and dryer, and a heat-pump water heater. Almost entirely LED lighting. Energy efficient windows and some insulation about fifteen years ago. I have smart control over the HVAC. Carefully crafted schedules for heat and cool, to maximize comfort and savings. I even circulate hot water, on demand, so the shower is instantly hot when I am ready. No wasted cold water down the drain. None of the changes made much difference in power usage except the for the heat pump(s.) My 2022 summer power usage peaked at $41 for the month of July. I was not stingy with the A/C. I keep the house toasty when I feel like and very cool compared to the 'recommended A/C temperature of 78.' (70 to 74 depending on mood.) I will spend less than seven-hundred dollars for power this year. Average about twenty-five hundred per year before the heat pump. And now it is comfortable, hot or cold weather. I cannot imagine living without an efficient variable speed heat pump system again. Indoor temperature is 100% stable all day long, no ups or downs. The heat pump energy savings are so good, a solar system is no longer an option for my house. -G
I am impressed with your figures but sadly you are still using units that no one has any interest in around the world. Apple+K keys gets you a ˚ symbol instead of using the ' which is useful information for you perhaps. I prefer my own system which does not use dallars at all but kWh which is what the whole world runs on and that is kept to a few kWh in summer or winter because I am stingy. But what can we expect from yanks? Waste, and further waste and self-destruction. OK but please stay at home!
Note on Freon: To damage the ozone layer, it has to get up there, which in practice it can't in any significant amount. But when DuPont's patent was about to expire, it was suddenly banned and everyone was forced to buy more expensive alternatives. Much like how when the riffraff started moving to coastal California, the rich homeowners put a stop to it in the name of environmentalism.
I'm going to give you the inside scoop about how this heat pump is going to work will be multiple small heat pumps just like in the vehicle and what they will do is string them together on the same shaft that way it can gain maximum efficiency and what it will do is physically only run one heat pump per room or two this way you can actually select the room that you want to have colder than the others and you can control the airflow individually to each room you can have heat running in one room and air condition running in another just depending on what the person in the room preferences and individual thermostats for each individual room this would allow ultimate efficiency combined with artificial intelligence to control the entire system as a whole... having all of the compressors hooked up on the same rotor means that they can individually kick in and if there's more than one of them kicking in they both work together so it helps get the other compressors up to speed and cuts down the energy loss. Because the system will be able to have multiple different heat pumps it can run one of them on air condition mode and the other on heat mode which will basically make dry air because once you heat up the air the moisture can be absorbed by the one cooling easier and you can control the actual humidity perfectly. Mark my words this will be how the system will work it will be for new construction and for retrofitting because you're able to hook up the individual ducts instead of the entire manifold which supplies all the ducts...
@@AquarianSoulTimeTraveler Starting January 1, 2023 all new systems in the US will no longer have R-410A. The new refrigerants are HFOs, cars have been switching over to HFOs since 2015ish.
@@markbeiser The “ozone hole” was a scam invented by DuPont. The truth is that Freon is toxic. It degenerates into deadly phosgene gas when exposed to open flame, and technicians used propane torches to search for Freon leaks. Non-toxic and safe carbon dioxide is the ideal refrigerant, but there’s no profit in it for DuPont.
Just a quick history lesson on REFRIGERANTS, Freon is a name brand. I was an HVAC technician so here's some info. R-410a was introduced as the alternative to CFC's (R-22) which depleted the ozone layer due to its chlorine molecule. But over time R-410a being an HFC, was found to contribute to green house gases due to its hydrogen molecule. So now we are tying propane based type refrigerants.
@@mikekelly5869 . Is that for reverse cycle air conditioning, or just for water heating? We've been using Japanese tech hot water heat pumps (Sanden, & Reclaim Energy) here in Australia for about 10 years (& personally at our house for 8 years) & I can testify are highly efficient & quiet.
Everything I’ve seen Musk say about HVAC already exists including whole home hepa systems and WiFi/programmable thermostats. Whatever they might come up with would need to be pretty groundbreaking
Heatpumps been used in Scandinavia for many years, both air to air and air to water, for underfloor heating, freon are not used anymore but another less damaging fluid, most here have a Cop value of 5, so 1 kw in get you 5 kw out, so very energy efficient

Hi, living in Miami in early 1980’s we had a “conventional AC freon system”. I calling it that as I’m not a AC engineer but compressor outside & air handler inside, small one zone house. We purchased the house new, and it came with a small heat exchanger outside the house, a device about the size of a shoe box mounted on the exterior wall. The compressor hot side freon was piped thru that small 1/4” maybe copper tubing to the box, thru a coil, that ran with water from the hot water tank immediately inside the wall in garage. So when the AC was in use, say almost 9-10 months of the year, I would turn off the electric HW CB and the AC used this device to lower the freon temp before the air cooling part of the compressor. Creating a very efficient system. So as a matter of fact the more hot water we used the better it worked? Basically unlimited free hot water and an air conditioner using presumably far less run time as a water based heat exchanger has to be multiple X more effective than an air based heat exchanger. Well I often wondered why every house in Fl, or anywhere else in the south didn’t have a unit like this. I can only guess that the “power companies” want to sell you electric not save electric. So maybe they bought the rights to the device and put it out of business. In summer I often just opened the HW taps in the house and let them run, i hate to waste water but it made a good system even work better! That house was the only house I’ve ever seen with that device. Well thats my 2 cents!
Saving 75% with a COP 5 heat pump and solar panels here in Sweden. No batteries yet, except for the ones that we can’t yet use V2G in our Tesla cars. But hope Powerwalls will soon be sold in Sweden to complete our system.
@@mikekelly5869 a average household needs like 30-40kW to keep everything running 24 hours in case of a blackout. Normal blackouts last 1-2 hours. But unrealistic and unnecessary for most people to buy 3 PowerWalls. Most people in the near future will buy a BEV with maybe 60-90kW batteries so V2G and V2H is a must. Because we can then balance the grid and at the same time earn money buy when price is low and use or sell when it’s high a bonus is that you have backup power. If you are not a technical genius you need one Powerwall to manage this task. The thing is that Elon so far is not willing to give us V2G or even V2H.
@@thescooterstore2813 If you need a battery, you can just buy a battery, any size, modular or otherwise. So far Powerwalls are nothing special. That might change, but if it does it will probably just make them smaller. A normal house might need 20 or 30 kWh to get over an extended outage of a few hours but unless people are doing things like using washing machines and dryers during the outage and the supply is down for significant timespans more than that is likely to be surplus to requirements. My own view is that if there's spare cash it's best spent on decent controls in the first instance so that you at least have UPS functionality and a rock steady waveform. Improved feed-in tariffs might make bigger batteries more financially viable in the future but I doubt it. Utilities are clever at making sure that customers always continue to pay them when everything is calculated over time and they usually don't like unpredictable supplies hitting their transmission network because such supplies are far more likely to cause imbalance than the other way around. Despite the lip service given by utilities the world over, they almost never encourage microgeneration, or even larger scale generation by non-utility entities, for example PV on large industrial roofs. It adversely affects their bottom line and when the chips are down they want to control generation and transmission because that's where they make their money.
"Freon" is a name brand, like Tylonol. The chemical is R-22 and it is obsolete. While it is still common, it is no longer produced or imported in many nations, including Canada. This is because it is a HCFC. Hydrochloroflorocarbon. The newer, "Puron" (also a name brand) R-410A is the current air conditioning refrigerant. It is an HFC, they removed the chlorine.
You never explained how efficiency will be helped by Tesla’s unit. Heat pumps are the future. I love Tesla/spacex. I don’t think there is some killer avenue that Tesla can go into to undercut the industry. Mitsubishi and Daikin are putting out every trick in the book as it is. There is no hesitancy to forge ahead in HVAC unlike the car industry 2007.
Yeah Musk is Dr Evil, but your criticism is bogus too! If you actually paid attention he took that long existing tech and dramatically improved it (unlike every HVAC company for past century....). He also said the engineering team deserved all the credit for the innovative redesigns.
So did he make it more efficient? Air conditioners/heatpumps might be 100 years old but up until recently heatpumps weren't very efficient at heating a home that is in a climate that gets below freezing. We now have heat pumps that can heat at 100% capacity to as low as - 22°f(-30°c). That's insane since it's over 3 times more efficient than electric heat and some are 4 times. When you use ground source heatpumps you can get 6 times more efficient vs electric heat.
It is honestly overdue to implement an updated version of heat pump technology in reducing global warming, where it is feasible (which is likely over 90% of the global market). It is an expensive transition though, and at least in the US, it is the best time ever to start this process due to the recent bill passed subsidizing heat pumps for home HVAC as well as water heating. In many cases up to 80% of the cost can be covered!
I have another idea about Ventilate room during winter without cooling it So - two tubes side to side all along , through one heat air going out while through other coming from outside air heating simultaneously Little bit of energy was needed in this case for actually push air But its much much less then in Heatpump scenario If compare it would be 1/100 for example or less , ...
Pause at 10:37. I invested in a Mitsubishi Zuba Central, in Quebec, where we spend weeks at -35C to -40C. Freeze your nose hair cold. And it cranks 22,000 BTU’s constantly because it uses an industrial compressor. And heats a basement and 2 stories. Because triple glass pane windows, insulated everything to the footing. It costs much more than a traditional (clanky) square thermal pump, but at max power sounds like a soft rain shower in db. My point; we don’t need Muskrat to « fix » our Thermo pump efficiency- just plan your thermal envelope and invest in a good system for years of trouble free use.
You barely touched on one of the major functions of car heating system. You mentioned the Octovalve which I'm fairly sure means nothing to most people. It is where all of the different coolants in the car come together and get sorted out depending on how they need to be treated. So if you are running on the highway and your electric motors and batteries are generating heat, and you also need cabin heat then motor heat can be harvested to make cabin heat more efficient. However when the conditions change and the cabin needs cooling or even the drive electrics need a cooling bost the various cooling fluids can be redirected so each takes the path that will get the desired results with the least amount of battery energy used to get the job done.
Don’t have this system but I have been thinking about underfloor heating running off a heat pump. Concrete has a greater thermal mass than air and would be so good to hear a large slab in winter and cool it in summer
I have a slab foundation and it absorbs heat and cold really well. The problem is that the slab is down low so it doesn’t cool upper floors in the summer or help heat the lower floors in winter. Def better for single story homes.
Also heard you can run into problems in spring days with wide temperature swings. Freeze at night and nice during the day. You still have a lot of thermal heat in the concrete but it warm out and it makes the house to hot.
I'd say just stick with water heater flooring. a heat pump would use to much energy overall and be next to useless since refrigerant pressures would not be stable since it's not consistent airflow/temperature plus during cooling season your floors would be cooled which for a concrete floor is next to useless.
@@Tah_Dot Underfloor heating from a HP is always water based. The HP runs refrigerant through a heat exchanger and heats or cools the water. In practice very few installations cool floors because there's little benefit but many drawbacks with this

Very informative… like most solutions it’s often a balance of several things that ends up being used. I am surprised no one has come up with modular system you could retrofit to your garage combining wind, solar and an air source heat pump feeding your electric car. Your utility would manage the system prioritising your needs first and any excess going back to the grid to support balancing the system and generating an income. In the UK we have all the component parts including a converted ICE car to electric for free (£0.04 kWh) for a runaround… we are getting there.

I live in the deep south of the Usa. The temp gets below 25* F for 2 -3 days every 3 years. The heat pumps we have are considered to be a failure as they will not keep a house at 70* F when the temp is 40* F or lower. They freeze up and stop working at about 32*F. Many people consider them to be a waste of money.

These can run on clean natural gas and my digital Honeywell is fully programmable with a work schedule,day,night etc and is controllable from my phone from anywhere in the USA.
In addition to my AC story below I had another older house, this one in Maine on the coast. Well this house had an 80 gallon electric resistance HW heater. Well several people told me , jeez you better get rid of that as it will kill you with electric bill. 4 kids, 3 girls, get the picture. However the HW heater had a time of day device that it only ran on “off peak” electric rates. So “on peak” say electric was maybe 10 cents KWH. Off peak was like 1 cent KWH. Peak was 8am to noon. Then 4pm till 8pm. Monday thru Friday. Weekends off peak. So the unit had an override button to enable HW to be produced during peak, at 10X the off peak price. I think in about 15 years I used it once or twice. Furthermore everything in the house that consumed electricity worked on the same cycle, in other words run the darn dishwasher or washing machine AFTER 8pm, HELLO. So not only was our electricity bill very modest we were helping the grid load by doing everything during the so called dump rate time of day. How simple is this, why doesn’t every house have this system. You can forget about building new power plants as the ones we have would be running much more efficiently eliminating the current peaks and troughs. Simple.
The innovation that tesla provided in heat pumps for its cars is not the basic principle that has been known for many decades but the correct sizing and combination of a series of parts that are normally found in a car that are combined into the OCTO valve and other components in a tesla. That is white makes it more efficient. They’ve been able to Combine components in one box,reduce the length of hose by 60% reduce the number of connections by 70% so of course it works better but just because of that, it does not mean that they have some miracle solution for buildings where the biggest single problem is interacting with the building itself which is not controlled. Every parameter and every requirement is known exactly inside the Tesla but those same values are all over the map with the house which is why Tesla will have no advantage and if they’re smart, as they are they will never enter that market.
I applied for grant from doe in 1977 to build an air conditioner the uses no electric power ...only sunlight. it was an over grown version of the (ice ball) camper fridge. I was beat out by a window sized solar heater made from beer cans!
It is not Freon, it is R410a, at least in North America most commonly. Freon is generally banned because it is super crazy damaging to the environment, a lot more than R410a. You could use a few others. Something often overlooked is propane is the least damaging refrigerant we have today; it is just flammable. Then again when the system is not supposed to leak and we use propane all of the time, it seems more hype then real problem. R410a has a boiling point of -48.5C, so this whole "it's too cold to boil" is made up by you. There is a problem in creating a big enough temperature differential and that is real for your Canadian climate. That 3x improvement in efficiency is more like if you are in Southern California. By the way I do have a heat pump while living in SoCal. Works great. Costs to run are modest with the biggest thing is energy is crazy expensive in SoCal. Even with the crazy energy prices, not too hard on the pocket book as it is really efficient. I think the big thing you need to think about, which is almost completely missed in this piece, is how to effectively use a heat pump and even air conditioner in a wide range of climates. You could for example get a Lennox "dual fuel" heat pump where if it is not too cold out, it is a regular heat pump. If it is like Canadian cold out, then it runs a little outdoor furnace to warm the refrigerant. Supposed to be super efficient at extracting the heat from the furnace bit and then warms the place like a typical heat pump would. Another year round option is either buried coils or bore holes in the ground and stuff the coil into them. The idea being underground is a more constant temperature, at least when you go deep enough, so then if it is super cold out, you get the heat from the relatively warm ground and in the summer you dump the heat into the relatively cool ground. Another play on this is say have the coil go around your pool for summer cooling. Water is a lot more dense than air, so is a much better thing to exchange heat with if you are looking for efficiency. Pools are never warm enough, even in SoCal, so a great place to dump heat in the summer, granted you do it right and don't end up with too many issues of a clogged system. Granted pools are high maintenance items so it is up to whatever you are willing to maintain ultimately determining what kind of setup will work for you. Maybe as an alternative have a pre-warming water tank before your water heater with the notion your air conditioner can dump heat into cool tap water. To help maximize efficiency, if you have ever had a pool, the water always stratifies heat wise so warm water is on top and cold water sinks to the bottom unless you go out of your way to mix it. So for your air conditioner running during the hottest part of the day / coming home from work while still hot out, have it draw from the bottom of the pre-warming tank and dump into the top. Then have the water heater draw from the top of the tank. I have noticed my inverter based ACs are far more efficient with cooler outside air to work with, so summer days I have worked late, I have noticed cooling down the house has used far less energy than say mid day cooling on the weekend when I am home all day. This extends that out into say the tap water is 20 C while the outside air is 40 C. The air conditioner using that 20 C water to cool the house may use say 1/4th the power or less for the same amount of cooling. 75% - 80% reduction in power for the same amount of cooling is huge. Then the water heater may draw in say 25 C water to warm instead of 20 C water and use less energy to warm it. Of course add in the super efficiency that Tesla has come up with to the above and you should have vastly more efficient cooling and heating that should work well anywhere depending on the exact setup you use. So for Canada, you best bet is to probably drill holes in the ground or at least so something like the Lennox "dual fuel" system. In SoCal, if I could do the extra water tank, I would be in pretty good shape as well as for people with a pool, if they could tap into that it would be good. I already have an efficient inverter based system with remote control, so already have a big leg up on those with more dumb and inefficient systems.
1st prize for the most exact explanation of a real situation which could be important to most people in USA. AND you didn't use the antiquated far in height nonsense when talking of temperature. Good point about the bottom of the pool being cool, surely some heatpump providers already use this fact in the land of huts? In my own case I simply bought a house with an infinite amount of water available which could be used as a heat source and also to generate electricity. There are billions of locations on the planet where others could do the same but they are slaves to some boss who will not let them live in a tolerable climate. If they had got an education then they could understand these points and also been useful to employers who want smart people and not just idiots who push buttons at the right time. Efficiency is the CORE or all this and animals have PERFECTED themselves to not need any of the above. OR you move out of the heat or out of the cold if it is uncomfortable. The birds even with small brains do this and most want nothing to do with humans as they regard us as ignorant, clumsy, dangerous and stubburn creatures who are not to be trusted. In 99.9% of cases they are right, but not always.
I was waiting for you to mention that heat pumps won’t work in cold temperatures have the same problem where I live. They have made improvements recently talk to an HVAC guy and he said that they’ve come out with one that now works down to 20 below but they still recommend having an additional heater in the home For heating considering sometimes we get down to 30 below for weeks or even 60 below at night occasionally by the way that’s Fahrenheit for anyone who’s trying to figure this out. Good job on the video really enjoyed all the information was a great review of some of the stuff I already knew In the Tesla information was really interesting.

Tesla is all about vertical integration, so it seems obvious to me that the next thing they do with their HVAC/HeatPump is integrate it with both solar and batteries. There's a concept called PVT, or PhotoVoltaic-Thermal, where you have a panel that collects both electrons from sunlight but also heat energy from the sun. The solar heat collected from these panels would then be transferred to the heat pump. The heat pump can also collect any excess heat produced by the Powerwall. This would result in cooler solar panels (which produce more energy and last much, much longer) and zero-cost heat energy that can be used to make hot water or warm the house. There are even thermal loops that can transform that heat energy into cooling energy through compressor loops.
Doesn't the existence of the term PVT give a clue to the fact that this is nothing new? PVT systems that also integrate heat recovery ventilation and domestic hot water are quite common these days, in fact many European countries have included them in mandatory building codes, to a greater or lesser extent depending on location and climate.
@@tonydeveyra4611 Well that's true, but in this case the whole thrust of the video is that what's presented is new, when it's really just a reheat of existing tech in a shiny box.
@@mikekelly5869 the opportunities for innovation are in manufacturing process and integration. I doubt any of the europeans have integrated PVT with a heat pump and a home battery's thermal management system.
@@tonydeveyra4611 Home batteries are not all that common in Europe, at least not big ones so there's usually little advantage in adding specific means of recovering heat from them. It's usually done passively or people just use their cars or domestic hot water as storage. As for integrated PV, almost every domestic system (as opposed to individual plant items) is sold with the express capability of integrating with whatever PV panels the user wants to use. The three manufacturers that spring to mind are Nibe, Panasonic (Aguarea) and Daikin (Althema), two of which are Japanese, not European, as you know. There are many other examples.
HEPA for homes is a thing as well as uvc bulbs And Tesla heat pumps are not any more efficient than home heat pumps. And no matter how efficient your heat pump is you're eventually going to have to switch to natural gas in cold climates. There just isn't enough heat. And the way Tesla firmware updated the heat pump in their cars to make more heat was to allow its cop to drop below 1 which means resistive heaters would have been more efficient. I'm not saying that the heat pump is a bad idea and electric cars from temperatures in the upper 60s all the way to the 10s they are more efficient. But in you have to switch to electric heaters same as you doing houses. The only difference is in houses you're doing a cost comparison of the natural gas which tends to be a quarter of the price of electricity so you need a cop of four and anything below a copy of four you switch to natural gas because it's cheaper not because it's more efficient. In a car you don't have the cost of electricity to worry about. You have a set amount of electricity that you can use and you need to use it in the most effective way.
This has much broader implications. The next step after the heat pump is the ERV. The Energy Recovery Ventilator, which can save heat on the exhaust end and moisture as well. The Passivhaus movement has been on this for 30 plus years.
In this video it is mentioned that heat pumps generally use Freon as refrigerant and the specific heat pump you show in 1:58 with a big X on it uses natural refrigerant, what is completely harmless to the environment while providing better operation conditions.
Freon is a brand name of DuPont. Refrigerant is something that boils and turns from a liquid to a vapor at a lower pressure and temperature absorbing heat. Reject heat at a higher temperature and pressure turns a vapor to a liquid.
Great explanation 👌about the heat pumps system usage in cars and housing infrastructure. We just have to make sure in Europe that we produce enough energy with our solar systems on the houses and apartment complexes. My impression (f. ex. in Germany) is that on a huge % Apartment Complexes don’t even give the possibility to load a electric vehicle and still have too little Solar systems on their roofs and Apartment and house owners would have to invest in new loading infrastructure with the pump connection that would need a “quick” political regulation to support investments as such and create a small business chain that has the knowledge and expertise to actually do the craftsman work. Sounds like a great technology. I wish our government would be open enough to invite you for consulting talks. And take quicker decisions not directly depending on an election outcome could be made. Thx for sharing.
Gonna take some time to convince me I had a A/C - heatpump - heppafilter decades ago ..... now admittedly technology has advanced, but by nature 'heating' is way slower than cooling in heat pumps and walking into a 30F house and waiting 2 hrs before taking my coats off doesn't exactly suit me ..... I already struggle with the initial warm up delay in ICE cas before getting heat . Now my home unit had 'auxiliary' resistive heating to compensate for delays (sadly they were burnt out) .... but I still think it is sonething needed for the initial warm up
FYI, keeping your air off while you're away isn't efficient 1. your fridge and freezer works harder 2. your walls and other belongings gain energy and store it as thermal mass so when you get home your a/c will run all day (and night) when you get back, just for saving your electricity for about 8 hours.
Heating or cooling is to replace energy lost through the walls etc. There is no free lunch. The greater the thermal gradient the greater the losses. Thermal mass just acts as a buffer. Fridge/ freezers are low part of utility bill.
@@GSimpsonOAM @g simpson That's my point, the drywall and the 'stuff' you have in your house will retain heat if your ac unit is off long enough to warm up then turned back on again. Try turning your air off completely in the summer for a weekend coming back turning the air on cooling the air then opening plate cabinet in the kitchen feeling the heat radiate off the plates for HOURS. ...And true fridges and freezers are a small part of your electric bill, but in a house that has heated up hotter than the outside temp that part becomes larger as they run continuously.
@@imzjustplayin I agree... to an extent, once that heat energy is in the walls it will work it's way in... eventually. it would help but not alleviate the issue. if that were the case just tripling the thickness of walls and insulation would completely negate the need for Tesla's heat pump.and save tons of co2 entering the atmosphere but you'd still have to leave your ac or heat running at least to a lower extent than that of while you're there.
Today most new buildings are adequately insulated. In the 70s most were not adequately insulated. However many buildings today allow to much air to flow through the walls. So when there is a rental breeze outside it will blow cold air into the building and hot air out the other side. Cracks in wall and gap about light fixtures and pipes and leaks through doors and windows are the biggest problems in most homes today.
As anyone knows that tech is expensive as electricity is utilized to create heat and more to move it. The best option that has been utilized for over 10k years but modified properly in the 1400's and subsequently in the 1940's in the USA is geothermal. Heat and coolness is produced "for free" by the ground and requires a fraction of electricity to circulate it into the house. It can work in any environment extreme heat or extreme cold. The only limitation is the available (depth) ground near the home. These systems can last 50 to 100 and more for the same cost or less in the replacement of these traditional heating/cooling system. And requires far less electricity to function. Per example if the exterior temp is 100⁰F the heat pump needs to work harder and longer to maintain an interior temp of 65⁰F whereas a geothermal the system draws the heat in the home into the (colder) ground and on it's return will draw the cold for the ground into the home. The only electricity use on these systems are for in floor radiant the use of pumps and the other option is to tie into the pre-existing HVAC system with pumps and an air exchange unit (transfer heat/cold to air). Tesla's tech is a cheap version of geothermal that has been utilized since the early 80's as fuel prices went down but 10 years prior geothermal was the way to go as it was the oil crisis and any and all fuel types were extremely expensive. We find ourselves again in such a situation and energy specialists all over the USA are constantly hammering for expensive technology. People wake and smell the roses. Fyi many homes are anyways connected to a heat source(furnaces) and AC unit. Now look into geothermal and also to better your insulation. A home in the south or in the north should have the same rating. It is there to prevent loss and the outside temp from entering. Most in Florida cool outside as the majority don't have any insulation. Same occurs in the north (Alaska, Oregon, Canada). Best way to notice if you are lacking insulation in winter is the lack of snow built-up on the roof. As proper insulation does not transfer to the roof therefore snow built-up is it's consequence
I’m a commercial HVAC technician. Besides the efficiency of the heat pumps constantly improving I haven’t seen anything on the horizon that would replace the ac concepts we currently have. Mitsubishi is pretty much top of the line and has been for a while
You can't expect a mechanic to suggest you walk to the bottom of your garden. No, fix the car so that you can drive there. Get outside your tiny box wizard and begin to see the world around you.
I have a ground source heat pump with radiant floor heating. It also supplies preheated water to my water heater. Also have a heat pump water heater which is a huge energy saver. I have 8kw of solar which produces enough energy to drive my EV 40,000 miles per year.
The FIRST sensible comment here from someone who clearly is using his brain! What do you mean by "miles"? IS that not something that was used on the Apollo pretend flight to "moon"?
I believe this is only one prong of a multi prong approach which also requires that we build and operate our homes to be more efficient. Passive home standards go along way towards reaching this goal where a car sized heat pump may be all you need for a small home.
What you want to develope is a smart central air system . Most houses have maybe 10 rooms on average and most times those rooms are not occupied which you don't need to heat or cool those rooms most of the time . Same for when you sleep . You only need the bedroom for that climate control bedroom . Also you may want varying temperatures in different rooms . Most central air systems have very different tempature from one room to another depending on the rooms closest and farthest from the air handler . You would needed a smart variable speed motors and smart ducts that limit airflow or raise it depending on occupancy and comfort . Each room would need a monitoring device for tempature and many things do this already . The heat pump itself is not much different than a traditional system . If you have high electrical prices it's not going to lower your bill . The way the air is moved is where you can make the savings . Now their are some companies that have developed these systems but adapting them to existing systems that depend on a specific amount of airflow could damage the blower motor . So that motor has to reduce it's rpms to match any reduced airflow which would need a variable speed motor . The technology is there and the saving s in energy costs can offset upfront cost . The big factor is comfort and that will greatly improve . Let's get going elon . It's there for the taking
How would your thinking change if you had your own solar PV capability, both partial solar as is the case with many homes, or a zero carbon system (100% PV) if you have space for a ground system, which I do?
@@davidfellowes1628 Solar has it's limitations . I hooked up electrical for a generator for a off grid residence who had solar battery system because it wasn't enough electrical for their needs . A year later he wished he got a bigger generator. Solar is great but by itself it doesn't provide enough power for high draw items like air conditioning ,Electric heat appliances .
I’m a HVAC designer. All of technology already exists, and has for decades. Mitsubishi, Fujitsu, Daiken other leading manufacturers have very advanced systems systems with low ambient heat pump, indoor air quality from bipolar ionization, UV filter and ye, HEPA. This premium equipment is less common due to initial cost.
Thanks for the great video. It was interesting hearing that Elon and I agree on this one. I think the idea of a heat pump is great, but it's got to be quiet. I live in a condo, so my neighbours are close by. I really don't want to listen to my neighbour's heat pump all night long. Until it's quiet it's not going to viable. 58 decibels is currently the best I've seen. I would think 30 decibels is where it be reasonable to consider the switch.
Let’s pray that Tesla develops HVAC systems that use safe and non-toxic carbon dioxide for their refrigerant. DuPont advertised Freon as safe and non-toxic, and this enabled widespread acceptance of refrigeration after WWII, but Freon was extremely dangerous because it disintegrates into deadly phosgene gas---the deadliest war gas of WWI----when it is exposed to open flame, and air conditioning technicians typically used propane torches to search for Freon leaks. No doubt other DuPont hydrocarbon refrigerants are similarly toxic. The trouble is, carbon dioxide is practically free, and it offers no profit for DuPont or anybody else. Remember how firemen, police, and other “rescue workers” suffered a mysterious pulmonary sickness when the World Trade Center in New York was demolished? That is because those buildings used Freon for their air conditioning, and the air conditioning systems were custom-designed for the buildings and could not be adapted to the new refrigerants that replaced Freon. When the buildings were demolished using Thermite, which generates intense heat that melts steel, the Freon was converted to phosgene gas. Small wonder that so many people got sick. Corporate law is an open invitation to commit murder and even mass-murder, because it isolates the investors and officers of corporations from lawsuits, and therefore from responsibility for their crimes. Corporations live forever, and have more legal rights than a living human being. They were a problem in Britain even before the American Revolution, and the American “Founding Fathers” regarded them as a social and political menace. Time has proved them right. Dracula is real.
INSULATION! Most efficient means nothing if the house was not insulated well. Owned several poorly insulated homes in the past including overseas. Our final home target was to have the best insulated home for its size. We accomplished it, 109 degrees outside in door temp 78-82 no ac running. The goal has to be insulation and then make the appliances use less power, amps, watts etc to do the work.
My home has been running on one since 1973. There was a major movement towards electrification that came with the development of nuclear plants. Soon after, Three Mile Island was used as proof of flirting with Armageddon, advancements in nuclear ceased and guess who dominated energy for another half century and running. Heat pump advancements have not ceased however and the model y car pump is great advancing engineering.
Yes in Nebraska or Chenzolange or Missathutets. But elsewhere we have known HP for hundreds of years but you were kept in the dark and used and abused but didn't understand.
I prefer using thermostats with timers. If I stay up late one night, I still want to heat to turn down and will just use a blanket. Smart homes would most likely increase my energy use.
Smart thermostats conform to just about whatever you want and you can control it while you're laying in bed if you want. My power company actually offered a rebate so they can adjust my thermostat during peak summer loads to reduce overall grid use. It would be nice to see them let the homeowner set the temp based on outside weather and possibly monitor for open windows and doors.
9:17 an EV heater or any electric heater actually have very low resistance. This low resistance (see Ohms law) allows high current flow and heating element to get hot.
Refrigerant is not super cold.. It might boil at - 40 atmospheric pressure but not inside of a sealed unit.. It enters the evaporator a hot liquid. You can manipulate the boiling point of a liquid by manipulating the pressure above the liquid, And it's refrigerant, Not freon! Freon as a brand name Dupont labeled for R22 specifically.
Compressing a gas makes it hotter. Droping the pressure causes the gas to cool. An air conditioner only cools and has two heat exchangers and compressor (increases pressure) and an expansion valve (reduces pressure). Heat pumps add valve and an additional expansion valve that allow the process to be revised.
these are the vital innovations needed for The Future(tm): electric cars, and heat pumps ... also, viking landers on mars - next up, that radical innovation _disco music_ wow, the future sounds like a pretty cool place - I know jimmy carter's really excited by it
Heat pumps only benefit areas where electricity is cheaper than burning natural gas on site. My city is the opposite, though heat pumps would do wonders due to our winters being mild lowest it gets is about 25°F, it's cheaper here to burn gas on site.
I don't own a Tesla HP but I do own a Daiken HP that can be firmware updated, I can control temps and ranges from an app on my phone and I have a two stage filter system including HEPA and ionization filters. We run completely electrical in my house except for propane on demand hot water and factoring that in, I'd say along with some energy improvements like newer windows and doors, etc. Our overall electrical bill has dropped by more than 50%. Even in the summer when cooling.
I live in Ohio and run a "Dual Fuel" system. I use the heat pump down to 25F and then switch to the gas furnace at or below 25F. My heat pump is arguably not the most efficient, it was installed 10 years ago, but it is better than running natural gas 100% of the time heating is required. I would say I the gas furnace runs 30-40% of the time heat is required. Newer heat pumps, particularly VRF (variable refrigerant flow) and inverter heat pumps are incredibly efficient down to very low temps. I installed one a few years ago that was rated to heat at the rated capacity down to -13F. Not too bad. I still think there will be times when resistance heat or gas will be required as a back up, especially in colder climates. Curious to see what improvements Elon has really made to improve the heat pump beyond what an inverter or VRF can do.
I live in northern ND and we have long periods of minus 30 or colder at night with daytime highs of only minus 20. however in the summer highs over 100 do happen several times per summer. it appears the heat pump won't work well in the winter for us. I'm all for it if it makes financial sense. not going to spend thousands on equipment to save a few dollars on natural gas. natural gas is extremely abundant here so it's pretty cheap.
I would hope that Tesla systems would at least offer high end systems with things that are missing in even SEER2 23 rated heat pumps. Accumulator; Rectifiers (liquid/gas seperators ahead of the expansion valves); Counter flow heat exchanger ahead of the evaporator coil; Desuperator to help heat the hot water when in the A/C mode. A (thermal) solar panel booster when operating as a heater is also a possibility.
Im a Hvac contractor. They already make air quality product that does better then tesla car filtration and there on the market. However it’s all based off of what people want to invest in there system. I have a dual fuel system and the highest seer trane variable speed heat pump here in michigan. It does quiet well and is efficient to about 17-23f degrees. Then the furnace takes over. They are getting closer to being more efficient but not quiet there natural gas furnaces are still more economically efficient then any heat pump in colder climate. Electric based heating system heat pump and furnaces are 100 percent efficient but not economically efficient in cold climates. Overall having a dual fuel vs just using propane/nat gas is more efficient until certain temp marks in a lot of instances however that is based on how much you will pay if you get a base line product or top of the line product will determine your efficiency. Just like anything you get what you pay for. I’d be interested in seeing what they come up with. However allow temps to change when you leave and return and programming stats to go down at night and go up during the day doesn’t really save you money just to be honest. Every time you do this your system has to reheat or cool/dehumidify the whole house and objects in it. when it does it utilizes more energy then keeping it a constant temp in the house. That’s why having a variable frequency drive on a heat pump maximizes efficiency while maintain most comfort. instead of change temp your change the speed of the compressor creating less energy consumption. You may save a few dollars a year possibly but also could pay more changing the temp and not keeping it constant. All depends on multiple factors. I don’t see him doing much in hvac field that would change anything maybe on the tech side but nothin more. I’ll be interested in seeing if he does though.
Very good video. I wonder though, why not use the heat pump system to heat the water for the house, or cool your refridgerator, or dry your clothes... why not produce a single unit that will take care of it all efficiently?
The problem with trying to heat water is that it needs to be heated to about 60degC. This requires the gas in the machine to be compressed to a much higher pressure than one dumping heat to ambient air temps. It is also at the top end of the operational range of the current range of refrigerants. We uses R717 which is one of the oldest but one of the most effective refrigerants but even that tops out at around 70degC We are designing a hot water heating system at work and requires 25bar pressure to operate whereas the normal pressure is 10bar. Its capacity will be approx. 5 mega Watts. The pressure ranges and demands of a refrigerator and a dryer are quite different and so better to keep them as independent units.
@@GSimpsonOAM Best answer yet. Someone who can use English to transfer ideas! Seldom on this YT trash page. R717 and producing 5MW? That sounds like fantasy. Or are you heating a factory?
@@kennethkeen1234 Yes, heating water for a factory. Although a friend with several teen-age daughters could have done with it. His hot water bill was horrendous.
BRILLIANT for Persons suffering with multiple airborne allergies, I currently live in a gas heated apartment and have been using multiple air cooling, circulating and hepta air filter devices and have not found the right balance for air quality.

thermal energy is best in space but under the ground about 3 feet down will be cool around the same temp all year so in the summer it cools you and in the winter it heats you. You don't need to use energy to move heat up you can use low pressure heat pipes for that you only need to pump a liquid up to use it as cooling but it's free heat just need to use a water pump to use it for cooling but moving water is more efficient than running a air compressor
Without a discussion of latent heat of vaporization, this is a pretty lackluster explanation of heat pumps. The compressor does not actively add heat to the process, it is a side effect. Heat pumps move heat, and they can do this due to the "magic" of latent heat.
Back in the mid to late 80’s I was stationed at the Naval Base in Norfolk, Virginia… I lived in Virginia Beach where we had a new town house built and they used a heat pump system way back then…
If the ambient temp outside is below freezing it will freeze your condenser on a heat pump so it doesn’t need to be below the Freons boiling temperature to cause the system to malfunction in humid climates so that is why heat kits are installed on all heat pumps.
heat kits are to prevent the oil and or refrigerant from stalling the compressor. As for the freezing, that's what the defrost cycle is used. They make heat pumps that work down to -18F.
I've been using heatpumps for 30 years - the subject of my university degree in 1980. Sadly I've had to wait 40 years for others to catch up with this 1870 technology and am still 30 years beyond most having bought a property with 3 tons of water running through the basement per second. I tried to explain to Elon that in fact electric batteries were rubbish, toxic nonsense and were far inferior to fly-wheels - further technology from the 19th century which used to take busses up the Alps but were discontinued in the 1940s as it is deadly (for big tech) to have indestructible technology introduced to the public. Consumers have to be junkies for energy to be of any use and hence oil was chosen to rob them of their money. Air is free but water is hundreds of times more efficient in transferring energy from a to b and even greater if the water is falling. AND the atmosphere around a waterfall is enriched with positive ions which are beneficial to humans. But despite putting myself in the best position to be able to utilise all the free energy available, the people running the country where I have my home are strictly AGAINST being efficient and so to get the authorisation to install the perfect system would cost me 100,000 just for the paperwork - that is the best defence against someone getting something for free. So it is unimportant what physics will allow you - more significant is what economics will allow. And who rules economics - those who pay the politicians. And they get bought cheap because they are experts at nothing but talking and have no knowledge of the facts of life. 2022 10 28 14:59
Nice video. Finally, I've always been disappointed about how videos state heat pumps simply move heat around. I always felt that to be a dubious comment. I always knew that the refrigerant in an A/C was "COMPRESSED" and from simple HS chemistry that compressing a gas causes it to heat up ( it didn't transfer in from anywhere it had work done on it meaning ... energy in ) it was then pipped to the outside coil to have heat removed from it, before it was taken to the evaporative coil to be allowed to expand back into a gas which when a gas expands it removes heat from the surrounding environment. To me a heat pump, for a residential system, is just deciding which side of the compressor you are using inside your house. Are you using the compression side to get heat in or the evaporative side to get heat out.
Probably too demanding to get a comment here. This net is primarily used by children who are not yet hooked by porn or drugs in USA. Don't even TRY to teach adults from USA how to write down the time. 2022 10 28 15:19

"Freon" is a trade marked brand name of some refrigerants made by DuPont, there are many refrigerants. R-22 is likely what you are referring to. I has not come in any new systems since 2009, or been produced or imported for use in the US since 1/1/20. In the US, systems using it can still be charged with it, but it is getting very expensive. Current equipment uses R-410A, an HFC refrigerant, but all new equipment will be using HFO refrigerants starting 1/1/23. No telling how long before they find a problem with HFO refrigerants and move to something else...
wow I finally have a comment to make. You asked towards the end, who is doing this now, well I am. I did it in March 2021 demoed old system and installed heat pumps whole house no supplemental systems. quick stats. 1800sf home-Mojave Desert CA, previous system (as of 18 months ago) Cooling- 2 master cool swamp coolers on the roof 30 amp each, Heating-100amp electric forced air furnace. summer time 110*F 3-4 months a year, winter 20*F snow every 3-4 years only you know the desert does get cold, not Canada but hey, this is us, cold enough to be cold. that system it was still too hot in the summer (we roasted) and still too cold in the winder, we blasted heat or ac energy bill was really hi. really hi. Now since I installed heat pumps, one 35amp and one 45 amp heat and ac. Mr. cool oh ya. 6 zone, dual exterior pumps. we have to turn off the cool air in the summer, (my kids are polar bears now) and we feel nice in the winter. I removed the 2 master cool swamp coolers, and took the plunge based on science and removed the furnace. I felt so crazy 18 months ago thinking what an I doing here. but now after 18 months I would do this to any new home I ever purchase. those diy mr cool units came out total to around $6k, upfront cost or sure. but the return on lower energy bills and the quality of life is priceless. So totally believe in the technology, living breathing proof family of 5 (3 teens) are way more comfortable. scary at first, but I did it and the stats, real life experience, and data does not lie. ok I am done, -JM
Lol in sweden we have used heatpumps since the -80’s became common in the -90’s and is a demand nowdays to pass inspection on new bilding. And there is heatpumps avalibel that works down to -30celcius or you could use geothermal and dont need to worry about outside temp and get better cop too.
The marketing name ‘heat pump’ is a reversible heat pump. In the US deep south all home air coolers are heat pumps… just one way. They last X years. Make them two way and they will last X/y years.
I was waiting for you to mention that heat pumps won’t work in cold temperatures. have the same problem where I live. They have made improvements recently talk to an HVAC guy and he said that they’ve come out with one that now works down to 22 below efficiently and affectively but they still recommend having an additional heater in the home For heating considering sometimes we get down to 30 below for weeks or even 60 below at night occasionally by the way that’s Fahrenheit for anyone who wants to know. Just a sidenote this is excellent weather if you have a smoker 😋🤤 Good job on the video really enjoyed all the information was a great review of some of the stuff I already knew And the Tesla information was really interesting.

I'm a hvac contractor your description of a heat pump is good but as far as it not producing co2 is misleading because it depends on where the power comes from. In ohio the power they have is 92.6% coal power so you can explain how is there no co2 to the audience? Power does not come from thin air...

Needs chapters!!!! Waaaaaay Tooooooo much stuff I already know.
Freon is illegal in most countries including the US. We use a chemical that is similar to Freon but less harmful to the ozone layer. 134A Refrigerant.
In Australia heat pumps (usually referred to as reverse cycle Air Conditioners) are common. Water heat pumps are also rapidly increasing.
The good thing about Tesla is that the thought of the competition should drive the existing manufacturers to really up their R&D. Seems to me there would be significant advantages to combine hot water systems, home heating and cooling into one integrated product.
I worked with heat pumps here in the US (New York) back in 1980s. I'm not sure why the narrator thinks they have only been in common use for ten years. There are useful, but not a magic solution, their efficiency varies with ambient temperature.
rovert821
I think Steibel Eltron have a combi system doing both space heating and hot water.
However they utilise R134a, so not a fan.
Here in Australia, the best HWS heat pumps are Reclaim Energy, as are most efficient, refrigerant is CO2 & has a timer to utilise home solar PV when available.
So a super effective & cheap to run system.
I know right, its like they think Elon invented RCAC or something. The reality is the units here are cheap, its the install cost that bites!
Here in Ukraine we have such solutions. They install a heat accumulator (a large insulated tank of water 2-3 cubic meters in size), which is heated by any heat producer installed in the house (heat pump, solar water heater, gas heater, fireplace, etc). And there are energy consumers (heated floors/walls, hot water, etc.) which consume the energy from the accumulator via heat exchangers
@@serhii.almazov yeah, it’s called a thermal store here
Heat pump was a no brainer for me several years ago when I needed a new A/C unit anyway. Propane prices had been spiking and getting pretty ridiculous, so the heat pump gave me amazing savings. It paid for itself in 3 years.
local propane companies around here (California Sierra Nevadas) say propane is going up 53% so I did the same 4/5 ton heat pump for heating and a/c. Way cheaper.
Just as an addendum, my own experience with switching from a gas HVAC to a heat pump system was more beneficial than anticipated. My previous newer home had a natural gas (utility provided not a LP tank on site) system and was a single story ranch on a slab around 1500 ft sq. My new to me 2 story home w/ a walkout has a heat pump system and is about 3200 ft sq. Both homes were built within a few years of each other. My utility bill is the same for my current house as it was for the ranch! It is actually cheaper in the cooling season, but about 15% higher in the heating season. The overall average though is the same! I was able to further reduce my bill up to 20% by improving insulation around the house for less than $1k investment. I had used the same methods in my last home for a reduction of about 10%. Bigger bang for the buck with the heat pump system.
I'M ADDING SOLAR PANELS TO MY ROOF TO PAY FOR THE HVAC MULTI POINT SYSTEM
No one uses your units of "Ft" which were fine hundreds of years ago but for 95% of the world are OBSOLETE. Go to Uganda or Malta or China and catch up with new technology where they would never ever think of building huts to live in as it is seen Americans in the north part of that continent do. Huts are banned for living in, in Europe as we don't like to see what we own blow away when there is a strong wind. And if you start with TIME then you could actually in 50 years catch up with science around the world, instead of this nonsense 10/11/12 distraction when 2012 10 11 23:23 is PRECISE and understood by EVERYONE around the world except for Americans who live in the north.

You need to give actual numbers. Like how many KWH did you use in each house, How many heating days in your new house vs your old house. Heat pumps are not magic and electric is expensive. Electric is about 5 times more costly than Natural gas. Every video I watch about how great heat pumps are fail to give apples to apples comparisons.
I put a 13 kw solar system on my 1800 sq. ft rambler in 2015, replaced my oil furnance with a heat pump, and in 2018 bought a Tesla M3.
My total energy costs went from over $5,000 a year to about $500. The only gas I buy is for my wife's Honda Civic and my lawn mower. The heat pump uses the same heating ducts as my oil furnace did. The system works great, is quiet, and now provides AC in the Seattle area where I never thought I would need it. Thanks to Net Meeting, I bank excess solar power in the long summer days for use through most of the winter. Last year I had to pay about $50 for electricity for two months that were over the minimum $7.95 monthly charge. We did spend a lot of money on better insulation and weather stripping as our house was built in the 60's when oil was cheap.

In Minnesota, my heat pump system has worked wonderfully for over 10 years. It reverts to natural gas in extremely cold weather automatically. We also enjoy high solar gain from windows and the HVAC system adjusts the fan speed to distribute that heat evenly throughout the house.
Are you selling something or are you describing variable fan speed with way too many words? 🤣

We have used Geothermal heat pumps at our home for 30 years in Michigan. Wonderful technology. In summer it also makes free hot water from the heat extracted from our home. While our unit has backup electric resistance heaters, they have never been used. We also have many south facing windows which enable the house to pass 80 degrees on a sunny winter day even with temps near zero. The heat pump fan circulates this heat through the home.
the military has been using heat pumps for yearswith "emergency heaters" that get used to death in arctic conditions. The heating coils are exactly what you find in cheap 20$ portable heaters. The heat pump works better when trying to cool things dowm but is most eficient when you have a LOT of heat on one side or the other. In a desert there can be a cooling problem instead of a heating problem because the freon never condenses enough. We ended up having to adjust the presures in the systems to get enough cooling.
With recent heat waves here in the Pacific Northwest, we're exploring a retrofit whereby our very efficient gas-powered heater is replaced by a heat pump. Our system is a bit more complex than a typical forced air system because it heats water which is then pumped sequentially through 5 different radiant floor loops. By replacing the heating system with a heat pump it is hoped that warm water in the winter will be cooled in the summer. It is worth mentioning that the current heating system doesn't need to heat the water very much: water exiting the system into the loops runs about 85°, returning to the system only a few degrees cooler. So, we expect that, in the summer, water might only be need to be cooled to, say, 65° to achieve sufficient cooling to keep the house at a comfortable temperature. It's early days, but I'm hopeful.
You cannot cool the floors, usually, as that will lead to condensation and moisture problems. But if u only got ceramic floors or you dry the air in other ways, then maybe. In Sweden coolers are air based.
Heat rises off the floor. Cool won’t rise off the floor. It would just end up as a cold wet floor.
Cooled floors are a bit of a nightmare. They usually don't work very well unless there's a lot of direct solar incidence on the floor that re-radiates and generates a cooling load. Otherwise yiu just end up with cold feet and a condensation risk that needs careful control.
Your heat pump will require twice the "fossil fuel" to warm your home than your inexpensive gas heater uses. For cooling, fans, trees & an inexpensive swamp cooler in your attic space would save time, $ & effort.
Screw all that... Just do mini split and save the hassle. You can get up to a 5 head unit and have custom heating controls for individual rooms. You can even get cassette air handlers that hide in your ceiling and it looks just like a vent and nothing else.
in the mid '80s I sold a wide variety of heat pumps to the residential market. Living in Canada, I was often asked how a heat pump gets heat from cold air. I would ask the client and then quickly answer.. what is the difference between 10C and -10C? 20 degrees of heat! The heat pump extracts the heat from outside and moves it inside.
The biggest difference for most people is the temp coming out of the register in the house. An oil furnace or gas furnace delivers 110F and is very warm to touch. A heat pump delivers air at the register about 90F - problem is the body is at 98F, so it feels cool to the body.
Put your hand over the register, a gas/oil feels warm, and a heat pump at 90F against a 98F hand feels cool. Common question: How can that heat my home?? A house is usually 70F - the heat pump even at 90F is delivering 20F of heat. In the room it feels the same 70F.
Modern heat pumps are getting efficient - a significant saving in most of Canada at 30%
Great video I installed a mini split system four years ago and I’ve been very pleased I hardly ever turn on my gas furnace just use the heat pump to heat individual rooms. My system is considered a mini split. Which means one unit in each room. Disadvantage is air circulation small fans don’t push the air down the hallway necessarily. Extreme conditions I sometimes use a box fan to push the cool air around. I have a solar system from Tesla electric car model three and a small Jacuzzi (electric powered). My electric bill is still under $75 a month on average.
I’m in the HVAC field, what you are talking about is already been in practice for decades in the states. What he did in the Tesla is remarkable, taking commercial HVAC technology and put it in a car. Mitsubishi has taken it to the next level, heating and cooling from the same heat pump at the same time. It’s called VRF Technology. Now available for residential applications.
Europeans have been using it all the time!
Also your refrigerant cycle chart is oriented wrong as the high pressure vapor from the compressor is fed into the top of the condenser. And high pressure liquid comes from the bottom to head the metering device just before the evaporator.
The key to a heat pump working to cool your house is the refrigerant is compressed and heated up so that it is hotter than the outside air. The outside air the cools off the hot refrigerant so when it decompresses after the expansion valve it is now cooler than your indoor air. The opposite is true as well when it is run in reverse to heat your home. It has to cool the liquid to be colder than the outside air warms the refrigerant before being compressed to make it even hotter than your indoor air. The limitations are if it is too hot outside, the compressed refrigerant is at the same temp or cooler than the outside air and stops working. In reverse it can't cool the refrigerant below the temp of the outside air and stops working.
A heat pump is the same thing as a traditional AC when in cooling mode.
So you watched the video and regurgitated it - well done. I did that sort of thing when I was 8 years old too. What was your point?
@@kennethkeen1234 There is a reason heating oil and natural gas furnaces are used in very cold climates. They are more efficient. There is a reason evaporative cooling is used in extremely hot and dry climates. They are more efficient.
In my 2100 sq ft. ICF (Insulated Concrete Form) home here in South Alabama it cost $130 to cool my home, I use a wood stove during the "winter" weeks. I spray foamed the attic and keep a chocolate Easter Bunny in the attic for a gag sitting on top of the attic HVAC unit, he has been sitting there for several years and looks great.
"Winter weeks" sounds great! Many of us have "Winter months", lots and lots of them, and then we have Summer weeks if we're lucky or Summer days if we're not 🤣

In 1982 I purchased a house built in 1850 and had a long wood/oil furnace that gobbled up 2 cords (at a cost of $100) of wood the first winter in Minnesota. Before the onslaught of winter the following year I installed 20 KW of resistance heating in the duct work on the dual fuel program by the local rural electric utility. My heating bill went up to about $250 a month. The following year I purchased a used 3 ton heat pump, replaced the compressor, had outside help of an electrician and HVAC guy and my monthly bill dropped to less than $150. Go with the HEAT PUMPS ! ! !
You probably have the oldest house in USA - I have a modern house - 18th century and my neighbours' houses are from the 14th century but don't blow away in the wind!
Not sure what is new here? I have had a heat pump system in my house for the last 25 years with hepa filters due to wife's pollen allergies.
Also the current refrigerants are no longer bad for the ozone layer, there refrigerants were paused out a long time ago. Why call refrigerant Freon, it like calling every car in the world a Ford? I would be more impressed if Tesla used water vapour as a viable refrigerant. In cars. (Which is technically totally doable)
Not sure what Tesla is offering in this case what is not already tried and tested rechnology. Would be interesting to read the tech data,.and hopefully they made some efficiency gains.
Is there any evidence that Tesla has any plans whatsoever to get into residential (or commercial) HVAC? I don't see the business case for it, because Tesla doesn't have any new physics to bring to the table, and existing HVAC equipment is already pretty efficient.
I think they make shit up on this channel.Look how they say he’s doing something new every week or so 😝
HVAC equipment until very recently hasn't been all that efficient. Just recently I saw that there is a 6000 BTU A/C mini split that has an EER of 19 and a SEER of 33. This was unheard of 10 years ago, let alone even 2 years ago. Best EER for a 4 ton system is like an EER of 15 but again that's a very recent innovation. HVAC industry doesn't have a lot of investment in it like the tech industry because most consumers of that industry always buy the cheapest crap so not a lot of money goes towards most efficient equipment.
As a commercial HVAC technician, God I hope not. Newer equipment, especially process cooling or critical cooling is already so damn temperamental. Look at it sideways and it breaks.
Why get into it when they ban used refrigerants every 10 years or so?
@@ssaraccoii Reason refrigerants get banned every 10 years is cause patents run out. Studies (usually funded by refrigerant manufacturers like Dupont) all of a sudden discover those refrigerants are bad for the environment. But luckily those same manufacturer funding the environmental studies have new refrigerants with patents that are supposedly better for the environment ready to go. It's all a scam.
0:50 "...goes to controlling the temperature of our air...": And that is foolish. I never turn on the heat above 50 degrees. And I never turn on the A/C below 90 degrees.

Energy efficient windows and some insulation about fifteen years ago.
I have smart control over the HVAC. Carefully crafted schedules for heat and cool, to maximize comfort and savings. I even circulate hot water, on demand, so the shower is instantly hot when I am ready. No wasted cold water down the drain.
None of the changes made much difference in power usage except the for the heat pump(s.) My 2022 summer power usage peaked at $41 for the month of July. I was not stingy with the A/C. I keep the house toasty when I feel like and very cool compared to the 'recommended A/C temperature of 78.' (70 to 74 depending on mood.)
I will spend less than seven-hundred dollars for power this year. Average about twenty-five hundred per year before the heat pump. And now it is comfortable, hot or cold weather.
I cannot imagine living without an efficient variable speed heat pump system again. Indoor temperature is 100% stable all day long, no ups or downs. The heat pump energy savings are so good, a solar system is no longer an option for my house. -G
I am impressed with your figures but sadly you are still using units that no one has any interest in around the world. Apple+K keys gets you a ˚ symbol instead of using the ' which is useful information for you perhaps.

But what can we expect from yanks? Waste, and further waste and self-destruction. OK but please stay at home!
Note on Freon: To damage the ozone layer, it has to get up there, which in practice it can't in any significant amount. But when DuPont's patent was about to expire, it was suddenly banned and everyone was forced to buy more expensive alternatives. Much like how when the riffraff started moving to coastal California, the rich homeowners put a stop to it in the name of environmentalism.
It's the same story with 410A the patent will run out and they will look for the next Freon source to use.
I'm going to give you the inside scoop about how this heat pump is going to work will be multiple small heat pumps just like in the vehicle and what they will do is string them together on the same shaft that way it can gain maximum efficiency and what it will do is physically only run one heat pump per room or two this way you can actually select the room that you want to have colder than the others and you can control the airflow individually to each room you can have heat running in one room and air condition running in another just depending on what the person in the room preferences and individual thermostats for each individual room this would allow ultimate efficiency combined with artificial intelligence to control the entire system as a whole... having all of the compressors hooked up on the same rotor means that they can individually kick in and if there's more than one of them kicking in they both work together so it helps get the other compressors up to speed and cuts down the energy loss. Because the system will be able to have multiple different heat pumps it can run one of them on air condition mode and the other on heat mode which will basically make dry air because once you heat up the air the moisture can be absorbed by the one cooling easier and you can control the actual humidity perfectly. Mark my words this will be how the system will work it will be for new construction and for retrofitting because you're able to hook up the individual ducts instead of the entire manifold which supplies all the ducts...

Wrong
Just a quick history lesson on REFRIGERANTS, Freon is a name brand. I was an HVAC technician so here's some info. R-410a was introduced as the alternative to CFC's (R-22) which depleted the ozone layer due to its chlorine molecule. But over time R-410a being an HFC, was found to contribute to green house gases due to its hydrogen molecule. So now we are tying propane based type refrigerants.

Hi, living in Miami in early 1980’s we had a “conventional AC freon system”. I calling it that as I’m not a AC engineer but compressor outside & air handler inside, small one zone house. We purchased the house new, and it came with a small heat exchanger outside the house, a device about the size of a shoe box mounted on the exterior wall. The compressor hot side freon was piped thru that small 1/4” maybe copper tubing to the box, thru a coil, that ran with water from the hot water tank immediately inside the wall in garage. So when the AC was in use, say almost 9-10 months of the year, I would turn off the electric HW CB and the AC used this device to lower the freon temp before the air cooling part of the compressor. Creating a very efficient system. So as a matter of fact the more hot water we used the better it worked? Basically unlimited free hot water and an air conditioner using presumably far less run time as a water based heat exchanger has to be multiple X more effective than an air based heat exchanger. Well I often wondered why every house in Fl, or anywhere else in the south didn’t have a unit like this. I can only guess that the “power companies” want to sell you electric not save electric. So maybe they bought the rights to the device and put it out of business. In summer I often just opened the HW taps in the house and let them run, i hate to waste water but it made a good system even work better! That house was the only house I’ve ever seen with that device. Well thats my 2 cents!
Saving 75% with a COP 5 heat pump and solar panels here in Sweden. No batteries yet, except for the ones that we can’t yet use V2G in our Tesla cars. But hope Powerwalls will soon be sold in Sweden to complete our system.
What is the make and model of your COP 5 heat pump?

Why not just use a regular battery? Half the price and still has a ridiculously long payback period.
@@mikekelly5869 a average household needs like 30-40kW to keep everything running 24 hours in case of a blackout. Normal blackouts last 1-2 hours. But unrealistic and unnecessary for most people to buy 3 PowerWalls. Most people in the near future will buy a BEV with maybe 60-90kW batteries so V2G and V2H is a must. Because we can then balance the grid and at the same time earn money buy when price is low and use or sell when it’s high a bonus is that you have backup power. If you are not a technical genius you need one Powerwall to manage this task. The thing is that Elon so far is not willing to give us V2G or even V2H.
@@thescooterstore2813 If you need a battery, you can just buy a battery, any size, modular or otherwise. So far Powerwalls are nothing special. That might change, but if it does it will probably just make them smaller. A normal house might need 20 or 30 kWh to get over an extended outage of a few hours but unless people are doing things like using washing machines and dryers during the outage and the supply is down for significant timespans more than that is likely to be surplus to requirements. My own view is that if there's spare cash it's best spent on decent controls in the first instance so that you at least have UPS functionality and a rock steady waveform. Improved feed-in tariffs might make bigger batteries more financially viable in the future but I doubt it. Utilities are clever at making sure that customers always continue to pay them when everything is calculated over time and they usually don't like unpredictable supplies hitting their transmission network because such supplies are far more likely to cause imbalance than the other way around. Despite the lip service given by utilities the world over, they almost never encourage microgeneration, or even larger scale generation by non-utility entities, for example PV on large industrial roofs. It adversely affects their bottom line and when the chips are down they want to control generation and transmission because that's where they make their money.
"Freon" is a name brand, like Tylonol. The chemical is R-22 and it is obsolete. While it is still common, it is no longer produced or imported in many nations, including Canada.
This is because it is a HCFC. Hydrochloroflorocarbon. The newer, "Puron" (also a name brand) R-410A is the current air conditioning refrigerant. It is an HFC, they removed the chlorine.
Good to get straight info. Clearly not an American.
You never explained how efficiency will be helped by Tesla’s unit.
Heat pumps are the future. I love Tesla/spacex.
I don’t think there is some killer avenue that Tesla can go into to undercut the industry.
Mitsubishi and Daikin are putting out every trick in the book as it is.
There is no hesitancy to forge ahead in HVAC unlike the car industry 2007.
Tesla has nothing to do with HVAC in building the most important issue to solve is building proper insulation and those people never mention that!
@@alanmay7929 you forgot air sealing. But air sealing and insulation yes are the most important things.
all hail elon for making 100 year old tech that every major HVAC company already makes.
This is the world television producers protected us from.
Yeah Musk is Dr Evil, but your criticism is bogus too! If you actually paid attention he took that long existing tech and dramatically improved it (unlike every HVAC company for past century....). He also said the engineering team deserved all the credit for the innovative redesigns.
Lol I was seriously thinking the same.
Tesla is just over priced junk.
So did he make it more efficient? Air conditioners/heatpumps might be 100 years old but up until recently heatpumps weren't very efficient at heating a home that is in a climate that gets below freezing. We now have heat pumps that can heat at 100% capacity to as low as - 22°f(-30°c). That's insane since it's over 3 times more efficient than electric heat and some are 4 times. When you use ground source heatpumps you can get 6 times more efficient vs electric heat.
Obviously you didn’t watch the entire video because you would know that his team redesigned the “100” year old tech.
glad heat pump and geo thermal style is gaining more attention in the states. They're way more efficient and eco friendly.
It is honestly overdue to implement an updated version of heat pump technology in reducing global warming, where it is feasible (which is likely over 90% of the global market). It is an expensive transition though, and at least in the US, it is the best time ever to start this process due to the recent bill passed subsidizing heat pumps for home HVAC as well as water heating. In many cases up to 80% of the cost can be covered!
I have another idea about Ventilate room during winter without cooling it
So - two tubes side to side all along , through one heat air going out while
through other coming from outside air heating simultaneously
Little bit of energy was needed in this case for actually push air
But its much much less then in Heatpump scenario
If compare it would be 1/100 for example or less , ...
Ha yea and - tubes should be long , i mean very long
To provide decent heat exchange
There is a thing called a heat recovery ventilator that does what you are thinking about.
@@honeytubs yes its extremely efficient variation of those, when not a part but almost all amount of heat was recovered

I invested in a Mitsubishi Zuba Central, in Quebec, where we spend weeks at -35C to -40C. Freeze your nose hair cold. And it cranks 22,000 BTU’s constantly because it uses an industrial compressor. And heats a basement and 2 stories. Because triple glass pane windows, insulated everything to the footing.
It costs much more than a traditional (clanky) square thermal pump, but at max power sounds like a soft rain shower in db.
My point; we don’t need Muskrat to « fix » our Thermo pump efficiency- just plan your thermal envelope and invest in a good system for years of trouble free use.
You barely touched on one of the major functions of car heating system. You mentioned the Octovalve which I'm fairly sure means nothing to most people. It is where all of the different coolants in the car come together and get sorted out depending on how they need to be treated. So if you are running on the highway and your electric motors and batteries are generating heat, and you also need cabin heat then motor heat can be harvested to make cabin heat more efficient. However when the conditions change and the cabin needs cooling or even the drive electrics need a cooling bost the various cooling fluids can be redirected so each takes the path that will get the desired results with the least amount of battery energy used to get the job done.
Don’t have this system but I have been thinking about underfloor heating running off a heat pump. Concrete has a greater thermal mass than air and would be so good to hear a large slab in winter and cool it in summer
I have a slab foundation and it absorbs heat and cold really well. The problem is that the slab is down low so it doesn’t cool upper floors in the summer or help heat the lower floors in winter. Def better for single story homes.
@@Martocciaweb yep. Single story is ideal it would seem. Obviously a consideration on brand new builds.
Also heard you can run into problems in spring days with wide temperature swings. Freeze at night and nice during the day. You still have a lot of thermal heat in the concrete but it warm out and it makes the house to hot.
I'd say just stick with water heater flooring. a heat pump would use to much energy overall and be next to useless since refrigerant pressures would not be stable since it's not consistent airflow/temperature plus during cooling season your floors would be cooled which for a concrete floor is next to useless.
@@Tah_Dot Underfloor heating from a HP is always water based. The HP runs refrigerant through a heat exchanger and heats or cools the water. In practice very few installations cool floors because there's little benefit but many drawbacks with this
I've had a 18 seer heat pump for the last 25 years I'm way ahead of the Tesla's curve along with super insulation along with 8 in of continuous polyisocyanate insulation

Very informative… like most solutions it’s often a balance of several things that ends up being used. I am surprised no one has come up with modular system you could retrofit to your garage combining wind, solar and an air source heat pump feeding your electric car. Your utility would manage the system prioritising your needs first and any excess going back to the grid to support balancing the system and generating an income. In the UK we have all the component parts including a converted ICE car to electric for free (£0.04 kWh) for a runaround… we are getting there.
Have you got info on your ICE conversion?

I'm going to give you the inside scoop about how this heat pump is going to work will be multiple small heat pumps just like in the vehicle and what they will do is string them together on the same shaft that way it can gain maximum efficiency and what it will do is physically only run one heat pump per room or two this way you can actually select the room that you want to have colder than the others and you can control the airflow individually to each room you can have heat running in one room and air condition running in another just depending on what the person in the room preferences and individual thermostats for each individual room this would allow ultimate efficiency combined with artificial intelligence to control the entire system as a whole... having all of the compressors hooked up on the same rotor means that they can individually kick in and if there's more than one of them kicking in they both work together so it helps get the other compressors up to speed and cuts down the energy loss. Because the system will be able to have multiple different heat pumps it can run one of them on air condition mode and the other on heat mode which will basically make dry air because once you heat up the air the moisture can be absorbed by the one cooling easier and you can control the actual humidity perfectly. Mark my words this will be how the system will work it will be for new construction and for retrofitting because you're able to hook up the individual ducts instead of the entire manifold which supplies all the ducts...
You don’t know what you are talking about.
And from the lack of punctuation above you can't write.
It would be cheaper, easier and more efficient to install any of the many VRF or VRV systems that have already been on the market for thirty years.

I live in the deep south of the Usa. The temp gets below 25* F for 2 -3 days every 3 years. The heat pumps we have are considered to be a failure as they will not keep a house at 70* F when the temp is 40* F or lower. They freeze up and stop working at about 32*F. Many people consider them to be a waste of money.
Years beyond USA in Europe yet yanks STILL rant on in far in height nonsense and mules and feet and pigeons and horses, jesus sad to have to wade through all this trash which was discarded 150 years ago.

These can run on clean natural gas and my digital Honeywell is fully programmable with a work schedule,day,night etc and is controllable from my phone from anywhere in the USA.
In addition to my AC story below I had another older house, this one in Maine on the coast.
Well this house had an 80 gallon electric resistance HW heater. Well several people told me , jeez you better get rid of that as it will kill you with electric bill. 4 kids, 3 girls, get the picture.
However the HW heater had a time of day device that it only ran on “off peak” electric rates. So “on peak” say electric was maybe 10 cents KWH. Off peak was like 1 cent KWH. Peak was 8am to noon. Then 4pm till 8pm. Monday thru Friday. Weekends off peak. So the unit had an override button to enable HW to be produced during peak, at 10X the off peak price. I think in about 15 years I used it once or twice. Furthermore everything in the house that consumed electricity worked on the same cycle, in other words run the darn dishwasher or washing machine AFTER 8pm, HELLO. So not only was our electricity bill very modest we were helping the grid load by doing everything during the so called dump rate time of day.
How simple is this, why doesn’t every house have this system. You can forget about building new power plants as the ones we have would be running much more efficiently eliminating the current peaks and troughs. Simple.
The innovation that tesla provided in heat pumps for its cars is not the basic principle that has been known for many decades but the correct sizing and combination of a series of parts that are normally found in a car that are combined into the OCTO valve and other components in a tesla. That is white makes it more efficient. They’ve been able to Combine components in one box,reduce the length of hose by 60% reduce the number of connections by 70% so of course it works better but just because of that, it does not mean that they have some miracle solution for buildings where the biggest single problem is interacting with the building itself which is not controlled. Every parameter and every requirement is known exactly inside the Tesla but those same values are all over the map with the house which is why Tesla will have no advantage and if they’re smart, as they are they will never enter that market.
I applied for grant from doe in 1977 to build an air conditioner the uses no electric power ...only sunlight. it was an over grown version of the (ice ball) camper fridge. I was beat out by a window sized solar heater made from beer cans!
You were well ahead of the posse! Great thinking to come up with that so long ago when solar wasn't much of a thing outside the spave programme.
@@mikekelly5869 the spave? What in god's name is this - kuntucky special club?
It is not Freon, it is R410a, at least in North America most commonly. Freon is generally banned because it is super crazy damaging to the environment, a lot more than R410a. You could use a few others. Something often overlooked is propane is the least damaging refrigerant we have today; it is just flammable. Then again when the system is not supposed to leak and we use propane all of the time, it seems more hype then real problem. R410a has a boiling point of -48.5C, so this whole "it's too cold to boil" is made up by you. There is a problem in creating a big enough temperature differential and that is real for your Canadian climate. That 3x improvement in efficiency is more like if you are in Southern California.
By the way I do have a heat pump while living in SoCal. Works great. Costs to run are modest with the biggest thing is energy is crazy expensive in SoCal. Even with the crazy energy prices, not too hard on the pocket book as it is really efficient.
I think the big thing you need to think about, which is almost completely missed in this piece, is how to effectively use a heat pump and even air conditioner in a wide range of climates. You could for example get a Lennox "dual fuel" heat pump where if it is not too cold out, it is a regular heat pump. If it is like Canadian cold out, then it runs a little outdoor furnace to warm the refrigerant. Supposed to be super efficient at extracting the heat from the furnace bit and then warms the place like a typical heat pump would.
Another year round option is either buried coils or bore holes in the ground and stuff the coil into them. The idea being underground is a more constant temperature, at least when you go deep enough, so then if it is super cold out, you get the heat from the relatively warm ground and in the summer you dump the heat into the relatively cool ground.
Another play on this is say have the coil go around your pool for summer cooling. Water is a lot more dense than air, so is a much better thing to exchange heat with if you are looking for efficiency. Pools are never warm enough, even in SoCal, so a great place to dump heat in the summer, granted you do it right and don't end up with too many issues of a clogged system. Granted pools are high maintenance items so it is up to whatever you are willing to maintain ultimately determining what kind of setup will work for you.
Maybe as an alternative have a pre-warming water tank before your water heater with the notion your air conditioner can dump heat into cool tap water. To help maximize efficiency, if you have ever had a pool, the water always stratifies heat wise so warm water is on top and cold water sinks to the bottom unless you go out of your way to mix it. So for your air conditioner running during the hottest part of the day / coming home from work while still hot out, have it draw from the bottom of the pre-warming tank and dump into the top. Then have the water heater draw from the top of the tank. I have noticed my inverter based ACs are far more efficient with cooler outside air to work with, so summer days I have worked late, I have noticed cooling down the house has used far less energy than say mid day cooling on the weekend when I am home all day. This extends that out into say the tap water is 20 C while the outside air is 40 C. The air conditioner using that 20 C water to cool the house may use say 1/4th the power or less for the same amount of cooling. 75% - 80% reduction in power for the same amount of cooling is huge. Then the water heater may draw in say 25 C water to warm instead of 20 C water and use less energy to warm it.
Of course add in the super efficiency that Tesla has come up with to the above and you should have vastly more efficient cooling and heating that should work well anywhere depending on the exact setup you use. So for Canada, you best bet is to probably drill holes in the ground or at least so something like the Lennox "dual fuel" system. In SoCal, if I could do the extra water tank, I would be in pretty good shape as well as for people with a pool, if they could tap into that it would be good. I already have an efficient inverter based system with remote control, so already have a big leg up on those with more dumb and inefficient systems.
1st prize for the most exact explanation of a real situation which could be important to most people in USA. AND you didn't use the antiquated far in height nonsense when talking of temperature. Good point about the bottom of the pool being cool, surely some heatpump providers already use this fact in the land of huts?
In my own case I simply bought a house with an infinite amount of water available which could be used as a heat source and also to generate electricity. There are billions of locations on the planet where others could do the same but they are slaves to some boss who will not let them live in a tolerable climate. If they had got an education then they could understand these points and also been useful to employers who want smart people and not just idiots who push buttons at the right time.
Efficiency is the CORE or all this and animals have PERFECTED themselves to not need any of the above. OR you move out of the heat or out of the cold if it is uncomfortable. The birds even with small brains do this and most want nothing to do with humans as they regard us as ignorant, clumsy, dangerous and stubburn creatures who are not to be trusted. In 99.9% of cases they are right, but not always.
I was waiting for you to mention that heat pumps won’t work in cold temperatures have the same problem where I live. They have made improvements recently talk to an HVAC guy and he said that they’ve come out with one that now works down to 20 below but they still recommend having an additional heater in the home For heating considering sometimes we get down to 30 below for weeks or even 60 below at night occasionally by the way that’s Fahrenheit for anyone who’s trying to figure this out. Good job on the video really enjoyed all the information was a great review of some of the stuff I already knew In the Tesla information was really interesting.

Tesla is all about vertical integration, so it seems obvious to me that the next thing they do with their HVAC/HeatPump is integrate it with both solar and batteries. There's a concept called PVT, or PhotoVoltaic-Thermal, where you have a panel that collects both electrons from sunlight but also heat energy from the sun. The solar heat collected from these panels would then be transferred to the heat pump. The heat pump can also collect any excess heat produced by the Powerwall. This would result in cooler solar panels (which produce more energy and last much, much longer) and zero-cost heat energy that can be used to make hot water or warm the house. There are even thermal loops that can transform that heat energy into cooling energy through compressor loops.
Doesn't the existence of the term PVT give a clue to the fact that this is nothing new? PVT systems that also integrate heat recovery ventilation and domestic hot water are quite common these days, in fact many European countries have included them in mandatory building codes, to a greater or lesser extent depending on location and climate.
@@mikekelly5869 something doesn't have to be new for it to be significant.
@@tonydeveyra4611 Well that's true, but in this case the whole thrust of the video is that what's presented is new, when it's really just a reheat of existing tech in a shiny box.
@@mikekelly5869 the opportunities for innovation are in manufacturing process and integration. I doubt any of the europeans have integrated PVT with a heat pump and a home battery's thermal management system.
@@tonydeveyra4611 Home batteries are not all that common in Europe, at least not big ones so there's usually little advantage in adding specific means of recovering heat from them. It's usually done passively or people just use their cars or domestic hot water as storage. As for integrated PV, almost every domestic system (as opposed to individual plant items) is sold with the express capability of integrating with whatever PV panels the user wants to use. The three manufacturers that spring to mind are Nibe, Panasonic (Aguarea) and Daikin (Althema), two of which are Japanese, not European, as you know. There are many other examples.
HEPA for homes is a thing as well as uvc bulbs And Tesla heat pumps are not any more efficient than home heat pumps. And no matter how efficient your heat pump is you're eventually going to have to switch to natural gas in cold climates. There just isn't enough heat. And the way Tesla firmware updated the heat pump in their cars to make more heat was to allow its cop to drop below 1 which means resistive heaters would have been more efficient. I'm not saying that the heat pump is a bad idea and electric cars from temperatures in the upper 60s all the way to the 10s they are more efficient. But in you have to switch to electric heaters same as you doing houses. The only difference is in houses you're doing a cost comparison of the natural gas which tends to be a quarter of the price of electricity so you need a cop of four and anything below a copy of four you switch to natural gas because it's cheaper not because it's more efficient. In a car you don't have the cost of electricity to worry about. You have a set amount of electricity that you can use and you need to use it in the most effective way.
This has much broader implications. The next step after the heat pump is the ERV. The Energy Recovery Ventilator, which can save heat on the exhaust end and moisture as well.
The Passivhaus movement has been on this for 30 plus years.
In this video it is mentioned that heat pumps generally use Freon as refrigerant and the specific heat pump you show in 1:58 with a big X on it uses natural refrigerant, what is completely harmless to the environment while providing better operation conditions.
Freon is a brand name of DuPont. Refrigerant is something that boils and turns from a liquid to a vapor at a lower pressure and temperature absorbing heat. Reject heat at a higher temperature and pressure turns a vapor to a liquid.
You can already buy HEPA filtration systems for your home. Either stand alone or integrated into your current HVAC system.
Great Tesla for Elon Musk's ideas !
Great explanation 👌about the heat pumps system usage in cars and housing infrastructure. We just have to make sure in Europe that we produce enough energy with our solar systems on the houses and apartment complexes. My impression (f. ex. in Germany) is that on a huge % Apartment Complexes don’t even give the possibility to load a electric vehicle and still have too little Solar systems on their roofs and Apartment and house owners would have to invest in new loading infrastructure with the pump connection that would need a “quick” political regulation to support investments as such and create a small business chain that has the knowledge and expertise to actually do the craftsman work. Sounds like a great technology. I wish our government would be open enough to invite you for consulting talks. And take quicker decisions not directly depending on an election outcome could be made. Thx for sharing.
Gonna take some time to convince me
I had a A/C - heatpump - heppafilter decades ago ..... now admittedly technology has advanced, but by nature 'heating' is way slower than cooling in heat pumps and walking into a 30F house and waiting 2 hrs before taking my coats off doesn't exactly suit me ..... I already struggle with the initial warm up delay in ICE cas before getting heat
.
Now my home unit had 'auxiliary' resistive heating to compensate for delays (sadly they were burnt out) .... but I still think it is sonething needed for the initial warm up
FYI, keeping your air off while you're away isn't efficient
1. your fridge and freezer works harder
2. your walls and other belongings gain energy and store it as thermal mass so when you get home your a/c will run all day (and night) when you get back, just for saving your electricity for about 8 hours.
Heating or cooling is to replace energy lost through the walls etc. There is no free lunch.
The greater the thermal gradient the greater the losses.
Thermal mass just acts as a buffer.
Fridge/ freezers are low part of utility bill.
@@GSimpsonOAM @g simpson That's my point, the drywall and the 'stuff' you have in your house will retain heat if your ac unit is off long enough to warm up then turned back on again. Try turning your air off completely in the summer for a weekend coming back turning the air on cooling the air then opening plate cabinet in the kitchen feeling the heat radiate off the plates for HOURS. ...And true fridges and freezers are a small part of your electric bill, but in a house that has heated up hotter than the outside temp that part becomes larger as they run continuously.
Most of those issues would go away if buildings had more insulation. Code minimum is far too low.
@@imzjustplayin I agree... to an extent, once that heat energy is in the walls it will work it's way in... eventually. it would help but not alleviate the issue. if that were the case just tripling the thickness of walls and insulation would completely negate the need for Tesla's heat pump.and save tons of co2 entering the atmosphere but you'd still have to leave your ac or heat running at least to a lower extent than that of while you're there.
Today most new buildings are adequately insulated. In the 70s most were not adequately insulated. However many buildings today allow to much air to flow through the walls. So when there is a rental breeze outside it will blow cold air into the building and hot air out the other side. Cracks in wall and gap about light fixtures and pipes and leaks through doors and windows are the biggest problems in most homes today.
As anyone knows that tech is expensive as electricity is utilized to create heat and more to move it. The best option that has been utilized for over 10k years but modified properly in the 1400's and subsequently in the 1940's in the USA is geothermal. Heat and coolness is produced "for free" by the ground and requires a fraction of electricity to circulate it into the house. It can work in any environment extreme heat or extreme cold. The only limitation is the available (depth) ground near the home. These systems can last 50 to 100 and more for the same cost or less in the replacement of these traditional heating/cooling system. And requires far less electricity to function. Per example if the exterior temp is 100⁰F the heat pump needs to work harder and longer to maintain an interior temp of 65⁰F whereas a geothermal the system draws the heat in the home into the (colder) ground and on it's return will draw the cold for the ground into the home. The only electricity use on these systems are for in floor radiant the use of pumps and the other option is to tie into the pre-existing HVAC system with pumps and an air exchange unit (transfer heat/cold to air). Tesla's tech is a cheap version of geothermal that has been utilized since the early 80's as fuel prices went down but 10 years prior geothermal was the way to go as it was the oil crisis and any and all fuel types were extremely expensive. We find ourselves again in such a situation and energy specialists all over the USA are constantly hammering for expensive technology. People wake and smell the roses. Fyi many homes are anyways connected to a heat source(furnaces) and AC unit. Now look into geothermal and also to better your insulation. A home in the south or in the north should have the same rating. It is there to prevent loss and the outside temp from entering. Most in Florida cool outside as the majority don't have any insulation. Same occurs in the north (Alaska, Oregon, Canada). Best way to notice if you are lacking insulation in winter is the lack of snow built-up on the roof. As proper insulation does not transfer to the roof therefore snow built-up is it's consequence
I’m a commercial HVAC technician. Besides the efficiency of the heat pumps constantly improving I haven’t seen anything on the horizon that would replace the ac concepts we currently have. Mitsubishi is pretty much top of the line and has been for a while
You can't expect a mechanic to suggest you walk to the bottom of your garden. No, fix the car so that you can drive there. Get outside your tiny box wizard and begin to see the world around you.
I have a ground source heat pump with radiant floor heating. It also supplies preheated water to my water heater. Also have a heat pump water heater which is a huge energy saver. I have 8kw of solar which produces enough energy to drive my EV 40,000 miles per year.
The FIRST sensible comment here from someone who clearly is using his brain! What do you mean by "miles"? IS that not something that was used on the Apollo pretend flight to "moon"?
I believe this is only one prong of a multi prong approach which also requires that we build and operate our homes to be more efficient. Passive home standards go along way towards reaching this goal where a car sized heat pump may be all you need for a small home.
What you want to develope is a smart central air system . Most houses have maybe 10 rooms on average and most times those rooms are not occupied which you don't need to heat or cool those rooms most of the time . Same for when you sleep . You only need the bedroom for that climate control bedroom . Also you may want varying temperatures in different rooms . Most central air systems have very different tempature from one room to another depending on the rooms closest and farthest from the air handler . You would needed a smart variable speed motors and smart ducts that limit airflow or raise it depending on occupancy and comfort . Each room would need a monitoring device for tempature and many things do this already . The heat pump itself is not much different than a traditional system . If you have high electrical prices it's not going to lower your bill . The way the air is moved is where you can make the savings . Now their are some companies that have developed these systems but adapting them to existing systems that depend on a specific amount of airflow could damage the blower motor . So that motor has to reduce it's rpms to match any reduced airflow which would need a variable speed motor . The technology is there and the saving s in energy costs can offset upfront cost . The big factor is comfort and that will greatly improve . Let's get going elon . It's there for the taking
How would your thinking change if you had your own solar PV capability, both partial solar as is the case with many homes, or a zero carbon system (100% PV) if you have space for a ground system, which I do?
@@davidfellowes1628 Solar has it's limitations . I hooked up electrical for a generator for a off grid residence who had solar battery system because it wasn't enough electrical for their needs . A year later he wished he got a bigger generator. Solar is great but by itself it doesn't provide enough power for high draw items like air conditioning ,Electric heat appliances .

I’m a HVAC designer. All of technology already exists, and has for decades. Mitsubishi, Fujitsu, Daiken other leading manufacturers have very advanced systems systems with low ambient heat pump, indoor air quality from bipolar ionization, UV filter and ye, HEPA. This premium equipment is less common due to initial cost.

Thanks for the great video. It was interesting hearing that Elon and I agree on this one. I think the idea of a heat pump is great, but it's got to be quiet. I live in a condo, so my neighbours are close by. I really don't want to listen to my neighbour's heat pump all night long. Until it's quiet it's not going to viable. 58 decibels is currently the best I've seen. I would think 30 decibels is where it be reasonable to consider the switch.
Let’s pray that Tesla develops HVAC systems that use safe and non-toxic carbon dioxide for their refrigerant. DuPont advertised Freon as safe and non-toxic, and this enabled widespread acceptance of refrigeration after WWII, but Freon was extremely dangerous because it disintegrates into deadly phosgene gas---the deadliest war gas of WWI----when it is exposed to open flame, and air conditioning technicians typically used propane torches to search for Freon leaks. No doubt other DuPont hydrocarbon refrigerants are similarly toxic. The trouble is, carbon dioxide is practically free, and it offers no profit for DuPont or anybody else. Remember how firemen, police, and other “rescue workers” suffered a mysterious pulmonary sickness when the World Trade Center in New York was demolished? That is because those buildings used Freon for their air conditioning, and the air conditioning systems were custom-designed for the buildings and could not be adapted to the new refrigerants that replaced Freon. When the buildings were demolished using Thermite, which generates intense heat that melts steel, the Freon was converted to phosgene gas. Small wonder that so many people got sick. Corporate law is an open invitation to commit murder and even mass-murder, because it isolates the investors and officers of corporations from lawsuits, and therefore from responsibility for their crimes. Corporations live forever, and have more legal rights than a living human being. They were a problem in Britain even before the American Revolution, and the American “Founding Fathers” regarded them as a social and political menace. Time has proved them right. Dracula is real.
INSULATION! Most efficient means nothing if the house was not insulated well. Owned several poorly insulated homes in the past including overseas. Our final home target was to have the best insulated home for its size. We accomplished it, 109 degrees outside in door temp 78-82 no ac running. The goal has to be insulation and then make the appliances use less power, amps, watts etc to do the work.
Heat pump has been widely in use for residential since 1990’s. Not last 10 yrs as you stated, just want to correct that.
My home has been running on one since 1973. There was a major movement towards electrification that came with the development of nuclear plants. Soon after, Three Mile Island was used as proof of flirting with Armageddon, advancements in nuclear ceased and guess who dominated energy for another half century and running. Heat pump advancements have not ceased however and the model y car pump is great advancing engineering.
Yes in Nebraska or Chenzolange or Missathutets. But elsewhere we have known HP for hundreds of years but you were kept in the dark and used and abused but didn't understand.
I prefer using thermostats with timers. If I stay up late one night, I still want to heat to turn down and will just use a blanket. Smart homes would most likely increase my energy use.
Smart thermostats conform to just about whatever you want and you can control it while you're laying in bed if you want. My power company actually offered a rebate so they can adjust my thermostat during peak summer loads to reduce overall grid use. It would be nice to see them let the homeowner set the temp based on outside weather and possibly monitor for open windows and doors.
A blanket! One of the FEW smart people here. Yanks are not allowed to use blankets. What if someone finds out you are using one?
Mr. Tesla was an INCREDIBLY SMART PERSON with his thinking.
9:17 an EV heater or any electric heater actually have very low resistance. This low resistance (see Ohms law) allows high current flow and heating element to get hot.
Refrigerant is not super cold.. It might boil at - 40 atmospheric pressure but not inside of a sealed unit.. It enters the evaporator a hot liquid. You can manipulate the boiling point of a liquid by manipulating the pressure above the liquid, And it's refrigerant, Not freon! Freon as a brand name Dupont labeled for R22 specifically.
Wait... isn't compressed gas cooling? And expanding gas heated? PV=nrT or something?
Compressing a gas makes it hotter. Droping the pressure causes the gas to cool. An air conditioner only cools and has two heat exchangers and compressor (increases pressure) and an expansion valve (reduces pressure). Heat pumps add valve and an additional expansion valve that allow the process to be revised.
these are the vital innovations needed for The Future(tm): electric cars, and heat pumps ... also, viking landers on mars - next up, that radical innovation _disco music_
wow, the future sounds like a pretty cool place - I know jimmy carter's really excited by it
Heat pumps only benefit areas where electricity is cheaper than burning natural gas on site. My city is the opposite, though heat pumps would do wonders due to our winters being mild lowest it gets is about 25°F, it's cheaper here to burn gas on site.
I don't own a Tesla HP but I do own a Daiken HP that can be firmware updated, I can control temps and ranges from an app on my phone and I have a two stage filter system including HEPA and ionization filters. We run completely electrical in my house except for propane on demand hot water and factoring that in, I'd say along with some energy improvements like newer windows and doors, etc. Our overall electrical bill has dropped by more than 50%. Even in the summer when cooling.
Not always the same answer. nasa. ;-)
Sensible answer yet no comments nor even "likes".
I live in Ohio and run a "Dual Fuel" system. I use the heat pump down to 25F and then switch to the gas furnace at or below 25F. My heat pump is arguably not the most efficient, it was installed 10 years ago, but it is better than running natural gas 100% of the time heating is required. I would say I the gas furnace runs 30-40% of the time heat is required. Newer heat pumps, particularly VRF (variable refrigerant flow) and inverter heat pumps are incredibly efficient down to very low temps. I installed one a few years ago that was rated to heat at the rated capacity down to -13F. Not too bad. I still think there will be times when resistance heat or gas will be required as a back up, especially in colder climates. Curious to see what improvements Elon has really made to improve the heat pump beyond what an inverter or VRF can do.
It would have been nice if you showed how Tesla's heat pump works more efficiently than a normal heat pump. Just saying that it does it wasn't enough
It's a secret!
Here is a man with standards. Shut up and go stand with the others in the long queues. 😅
I live in northern ND and we have long periods of minus 30 or colder at night with daytime highs of only minus 20. however in the summer highs over 100 do happen several times per summer.
it appears the heat pump won't work well in the winter for us. I'm all for it if it makes financial sense. not going to spend thousands on equipment to save a few dollars on natural gas. natural gas is extremely abundant here so it's pretty cheap.
Yep, that's too cold for air source heat pumps, you'd need deep ground source or boreholes.
I used to live in Not Dumb but moved as everyone else was dumb.
@@kennethkeen1234 What a thoughtful and intelligent comment you made!
I would hope that Tesla systems would at least offer high end systems with things that are missing in even SEER2 23 rated heat pumps. Accumulator; Rectifiers (liquid/gas seperators ahead of the expansion valves); Counter flow heat exchanger ahead of the evaporator coil; Desuperator to help heat the hot water when in the A/C mode. A (thermal) solar panel booster when operating as a heater is also a possibility.
Im a Hvac contractor. They already make air quality product that does better then tesla car filtration and there on the market. However it’s all based off of what people want to invest in there system. I have a dual fuel system and the highest seer trane variable speed heat pump here in michigan. It does quiet well and is efficient to about 17-23f degrees. Then the furnace takes over. They are getting closer to being more efficient but not quiet there natural gas furnaces are still more economically efficient then any heat pump in colder climate. Electric based heating system heat pump and furnaces are 100 percent efficient but not economically efficient in cold climates. Overall having a dual fuel vs just using propane/nat gas is more efficient until certain temp marks in a lot of instances however that is based on how much you will pay if you get a base line product or top of the line product will determine your efficiency. Just like anything you get what you pay for. I’d be interested in seeing what they come up with. However allow temps
to change when you leave and return and programming stats to go down at night and go up during the day doesn’t really save you money just to be honest. Every time you do this your system has to reheat or cool/dehumidify the whole house and objects in it. when it does it utilizes more energy then keeping it a constant temp in the house. That’s why having a variable frequency drive on a heat pump maximizes efficiency while maintain most comfort. instead of change temp your change the speed of the compressor creating less energy consumption. You may save a few dollars a year possibly but also could pay more changing the temp and not keeping it constant. All depends on multiple factors. I don’t see him doing much in hvac field that would change anything maybe on the tech side but nothin more. I’ll be interested in seeing if he does though.
Very good video. I wonder though, why not use the heat pump system to heat the water for the house, or cool your refridgerator, or dry your clothes... why not produce a single unit that will take care of it all efficiently?
The problem with trying to heat water is that it needs to be heated to about 60degC.
This requires the gas in the machine to be compressed to a much higher pressure than one dumping heat to ambient air temps.
It is also at the top end of the operational range of the current range of refrigerants.
We uses R717 which is one of the oldest but one of the most effective refrigerants but even that tops out at around 70degC
We are designing a hot water heating system at work and requires 25bar pressure to operate whereas the normal pressure is 10bar. Its capacity will be approx. 5 mega Watts.
The pressure ranges and demands of a refrigerator and a dryer are quite different and so better to keep them as independent units.
@@GSimpsonOAM Best answer yet. Someone who can use English to transfer ideas! Seldom on this YT trash page.
R717 and producing 5MW? That sounds like fantasy. Or are you heating a factory?
@@kennethkeen1234 Yes, heating water for a factory. Although a friend with several teen-age daughters could have done with it. His hot water bill was horrendous.
BRILLIANT for Persons suffering with multiple airborne allergies, I currently live in a gas heated apartment and have been using multiple air cooling, circulating and hepta air filter devices and have not found the right balance for air quality.

Video starts at 8:29, but you can start from the beginning if you're interested in some thermodynamics.
thermal energy is best in space but under the ground about 3 feet down will be cool around the same temp all year so in the summer it cools you and in the winter it heats you. You don't need to use energy to move heat up you can use low pressure heat pipes for that you only need to pump a liquid up to use it as cooling but it's free heat just need to use a water pump to use it for cooling but moving water is more efficient than running a air compressor
is this a lessen in Air Conditioning. what about using accustic refrigerating . or SOUND .
Without a discussion of latent heat of vaporization, this is a pretty lackluster explanation of heat pumps. The compressor does not actively add heat to the process, it is a side effect. Heat pumps move heat, and they can do this due to the "magic" of latent heat.
Back in the mid to late 80’s I was stationed at the Naval Base in Norfolk, Virginia…
I lived in Virginia Beach where we had a new town house built and they used a heat pump
system way back then…
I went to Newtownards last month. Lots of virgins there I bet.
If the ambient temp outside is below freezing it will freeze your condenser on a heat pump so it doesn’t need to be below the Freons boiling temperature to cause the system to malfunction in humid climates so that is why heat kits are installed on all heat pumps.
heat kits are to prevent the oil and or refrigerant from stalling the compressor. As for the freezing, that's what the defrost cycle is used. They make heat pumps that work down to -18F.
@@imzjustplayin 18fuck?
I've been using heatpumps for 30 years - the subject of my university degree in 1980. Sadly I've had to wait 40 years for others to catch up with this 1870 technology and am still 30 years beyond most having bought a property with 3 tons of water running through the basement per second.
I tried to explain to Elon that in fact electric batteries were rubbish, toxic nonsense and were far inferior to fly-wheels - further technology from the 19th century which used to take busses up the Alps but were discontinued in the 1940s as it is deadly (for big tech) to have indestructible technology introduced to the public. Consumers have to be junkies for energy to be of any use and hence oil was chosen to rob them of their money. Air is free but water is hundreds of times more efficient in transferring energy from a to b and even greater if the water is falling. AND the atmosphere around a waterfall is enriched with positive ions which are beneficial to humans.
But despite putting myself in the best position to be able to utilise all the free energy available, the people running the country where I have my home are strictly AGAINST being efficient and so to get the authorisation to install the perfect system would cost me 100,000 just for the paperwork - that is the best defence against someone getting something for free.
So it is unimportant what physics will allow you - more significant is what economics will allow. And who rules economics - those who pay the politicians. And they get bought cheap because they are experts at nothing but talking and have no knowledge of the facts of life.

Nice video. Finally, I've always been disappointed about how videos state heat pumps simply move heat around. I always felt that to be a dubious comment. I always knew that the refrigerant in an A/C was "COMPRESSED" and from simple HS chemistry that compressing a gas causes it to heat up ( it didn't transfer in from anywhere it had work done on it meaning ... energy in ) it was then pipped to the outside coil to have heat removed from it, before it was taken to the evaporative coil to be allowed to expand back into a gas which when a gas expands it removes heat from the surrounding environment.
To me a heat pump, for a residential system, is just deciding which side of the compressor you are using inside your house. Are you using the compression side to get heat in or the evaporative side to get heat out.

The only year round heat pump system is geothermal heatpumps.
Huge issue when temperature drops below 20 degrees and the resistance heat kick in Looking forward to new super efficient heat pump that can handle the extra cold days without spiking electricity unsay.
Ground sourced heat pumps have a stable 70 degree sink all year round.

Is Freon still allowed? Is that a Colorado thing that we use a replacement?
"Freon" is a trade marked brand name of some refrigerants made by DuPont, there are many refrigerants.
R-22 is likely what you are referring to. I has not come in any new systems since 2009, or been produced or imported for use in the US since 1/1/20. In the US, systems using it can still be charged with it, but it is getting very expensive.
Current equipment uses R-410A, an HFC refrigerant, but all new equipment will be using HFO refrigerants starting 1/1/23.
No telling how long before they find a problem with HFO refrigerants and move to something else...
wow I finally have a comment to make. You asked towards the end, who is doing this now, well I am. I did it in March 2021 demoed old system and installed heat pumps whole house no supplemental systems.
quick stats. 1800sf home-Mojave Desert CA, previous system (as of 18 months ago) Cooling- 2 master cool swamp coolers on the roof 30 amp each, Heating-100amp electric forced air furnace. summer time 110*F 3-4 months a year, winter 20*F snow every 3-4 years only you know the desert does get cold, not Canada but hey, this is us, cold enough to be cold. that system it was still too hot in the summer (we roasted) and still too cold in the winder, we blasted heat or ac energy bill was really hi. really hi.
Now since I installed heat pumps, one 35amp and one 45 amp heat and ac. Mr. cool oh ya. 6 zone, dual exterior pumps. we have to turn off the cool air in the summer, (my kids are polar bears now) and we feel nice in the winter. I removed the 2 master cool swamp coolers, and took the plunge based on science and removed the furnace. I felt so crazy 18 months ago thinking what an I doing here. but now after 18 months I would do this to any new home I ever purchase. those diy mr cool units came out total to around $6k, upfront cost or sure. but the return on lower energy bills and the quality of life is priceless. So totally believe in the technology, living breathing proof family of 5 (3 teens) are way more comfortable. scary at first, but I did it and the stats, real life experience, and data does not lie. ok I am done, -JM

The marketing name ‘heat pump’ is a reversible heat pump. In the US deep south all home air coolers are heat pumps… just one way. They last X years. Make them two way and they will last X/y years.
I was waiting for you to mention that heat pumps won’t work in cold temperatures. have the same problem where I live. They have made improvements recently talk to an HVAC guy and he said that they’ve come out with one that now works down to 22 below efficiently and affectively but they still recommend having an additional heater in the home For heating considering sometimes we get down to 30 below for weeks or even 60 below at night occasionally by the way that’s Fahrenheit for anyone who wants to know. Just a sidenote this is excellent weather if you have a smoker 😋🤤
