Furnaces: Why we still burn fuel to heat our homes
HTML-код
- Опубликовано: 27 фев 2017
- Ever wonder why the gas-fired furnace is still so prevalent? Why isn't electric heat the standard? Well, wonder no more as we explore the economic and practical reasons the gas-fired furnace is so ubiquitous in colder climates, and how in the future this is almost certainly going to change.

4 years later, he’s finally got that heat pump video
And yes, you should watch it
He has something like 5 now, and mentions them all the time. They are all great btw!
I love the way he dresses up for his vids. Shows how much heart and effort is put.
Also think he's giving a nod to Bill Nye. Just my theory.
Its a class act, for sure.

Hah, loving this televangelist look with the background and everything.
Yea i freaking love it! It is so classic!
However... I can't help but notice something in his older videos.....
Does he bleach his skin?¿? Look at his face in these older videos... around his eyes and mouth his skin is a more swarthy color....(exactly the areas where a person is forced to be extremely careful with skin bleaching products....
Idk man, but I can't get it out of my head when it hits my eyes!¡!
@@Renwoxing13 Who knows, could be that he is. It's probably more likely that its due to hay fever or some other allergy. That or our guy wasn't enough getting sleep; I mean, he does live in the middle of nowhere and had to drive several hours a day to get to and from his job, not to mention all the work he put into this channel in his spare time. I'd be exhausted myself with a schedule like that.
@@davidschaftenaar6530 The power of furnace compels you.
It's common with poor sleep
My parents have a geothermal unit with a heat pump, it works great! The emergency heat rarely ever kicks in.
My house has a 180,000 BTU natural gas furnace, and every bit of that is needed. Gets down to -35C during the long winter months where I live . I think it's a minor miracle that a single furnace manages to keep the house at a comfortable 21C when it's that cold outside. I don't even want to think about the wattage required to run an equivalent electric furnace.
30-40 kW is common gas furnace power here in Croatia, and we have pretty mild winters as a mediterranean country. I guess yours is even more powerful.
Insulation, especially attic insulation is key.
Steve F JEEZ! What brand?
Gas is toxic and dangerous.
There is a energy conversion web site that allows you to quickly compute various cost differences between energy types and equivalency. Also the state of Maine has a site with elaborate in-depth comparisons of home heating cost... .Mini split heat pumps are now the least expensive heating system to fuel.. Outside of a geo system of course but only by a very small petcentage.
Hurrah for district heating. Heating your home with waste heat from industry is great.
Waste heat? Could you please elaborate? I'm not familiar with the idea. (I know your comment is old but I'd really appreciate it)
District heating?
Blue51 never heard of District heating? It's where multiple properties are connected to one heat source. Might be a block of flats, a large housing estate or even an entire town. Hot water is piped to a heat exchanger in each property for heat and domestic hot water. There is usually a central boiler house but heat can come from any number of sources, such as waste heat from power generation, geothermal etc. The technology has been around for decades. Unfortunately in the U.K. it's still an expensive option- users are tied in to getting their heat from that source, and can't shop around for a cheaper supplier like an ordinary household can. It's been installed in large, new housing developments in London over the last few years, but residents are finding bills high as they pay more than the market rate for heat, plus an additional premium for the maintenance and eventual replacement of the system, boilers etc.
@@spencerwilton5831 as an American, I have no fucking clue what you're talking about.
Blue51 don't worry, we won't hold the fact that your country has one of the worst education systems in the developed world against you, nor the fact that you are ignorant of technology that has been employed worldwide for decades (including incidentally New York). What is particularly stupid though is commenting you have no clue about something which has been clearly explained only two or three comments earlier. Perhaps your American contaminated drinking water or hormone laden meat has damaged your brain?
Our house is well isolated and uses a heat pump with groundwater as a source. It was built around 1980 in Germany.
First, he said likely. Second, his video specifically is tailored for an American audience.

@@CrazyPlayer-pf2hv Admittedly, our neighbours thought we were stupid at the time. That we would suffocate. That we would freeze to death or soon put in some "actual" heating. So far nothing of the sort has happened and it seems that energy efficient heating systems have become far more socially accepted.
However if you truly think that this is "living in wealth" then don't look up what some run-of-the-mill BMW/Audi/Daimler engineers are earning, you'll have trouble breathing.

@@theragingplatypus4743 It depends on the part of the country. I've lived in homes with heat pumps w/ emergency resistive heat since ~ 1990. But we also have a bunch of cheap hydro and don't really get that cold.

Back in Poland we shovel coal into a heating furnace. My great Grandmother's cottage burns wood. Both coal and wood burning is still very popular, and other modern homes use radiators
Some places in Poland during the winter looks like Victorian London. As an photographer I was able to capture a few postapocaliptic views without much effort. Most common is that ineffective, primitive kind of furnace - which can be cheaply replaced to more ecological and more efficient, funded by various gov and local programs. There's some interest, but not much much. Why? Because people couldn't burn random shit. A lot of people burn trash (I mean all, especially plastics, even tires), so they don't have to buy that much coal + they pay less for the trash transport. Except they are poisoning everybody around and creating health crisis (mostly lungs and heart related diseases), it's win-win for them. It's illegal and there are cases when people paid fine for that. A few cases in an almost 40 mil country. I'm speaking mostly of my region, known for coal mining, so coal is really cheap here. And even a lot of illegal ways everybody knows to get coal.
As for radiators most blocks of flats from 60's-80's uses central heating system. I wonder what's the efficiency of that. Heating water, then it goes in the cold ground, then it heats your neighbor who don't even want it, then some unused spaces, then finally you. The good point is the source of heat - that could be easy modernized, changed from coal to gas etc. keeping the whole piping (let's say for 1000 flats, so a lot) intact.
@@KrzysiuNet Central heating system is quite effective and the pipes have abundant insulation in panel block buildings. In many cases, it is not even heat created at the place, it is supplied from some industry that creates a lot of it as a waste product. In our city, one entire district is heated from a garbage incinerator, which also has quite good filtration of dangerous particles and you can't smell anything as well. Safety and comfort. The pipes supplying heat go above ground in soma places and you can touch them - they are not hot at all.
@@petrmaly9087 I've checked the data and in case of my place individual meters are stands for about 40% of total meter (main, in the block of flats). That's why I was concerned, but I think it might be just an issue of the place I live, not the system itself. Same with industrial pipes - always a lot people hangs out there. I even burned my back once when I was sitting on it for a few seconds. Also the heating in my block is still on. The pipes aren't insulated and they are about 50°C now. One pipe in every room, in every flat, heating it 24h/day - there's about 1 km of such pipes per single block of flats (96 flats, 4 heated rooms, 2.5m height) that are heating place all the time. That's for sure is a waste.
@@KrzysiuNet As long as those losses are inside the building (corridors), it is still fine and insulation is very cheap. We do have some old insulation (mineral wool, aluminium foil, chicken wire, cardboard soaked in asphalt...) and some modern one. Also the building itself has outer casing insulation, almost all panel block buildings here have it now. The longer distance industrial pipes - you can't sit on them here as they have special caps - looks like a little roof - so the snow does not sit on it. In many cases the wall is a almost a meter thick and so cold on the outside snow and ice capping was an issue.
Well, 90% of electricity production in Poland is from coal. Also, Poland has not only the most polluted cities in Europe, but even on a global scale they're very polluted. It's a ecological catastrophe. If it weren't for EU regulations, Poland would probably look like a post-apocalyptic wasteland by now.
I love how I discovered this channel just recently and I've started studying to be an engineer with a focus on housing and construction laws and technology.
The funny thing is that so much brought up here in this video is and has been commonplace where I live in Sweden for so long. The insights provided here are just awesome and I agree all the way.
Thanks for making awesome content like this.
good luck on becoming an engineer!
Very good heating overview. Now it is 1 year later and R32 based heat pumps are on the market. They have an average "efficiency" of 510% and actually keep about 70-80% of the power output in cold weather.
Propane and propane accessories.
Actually this video refers to natural gas. Propane is much more expensive than efficient heat pumps. And heat pumps have became much better at heating down to low temps. I have a Fujitsu heat pump that kept the house warm when it was 5 degrees outside.

Nice step up in quality production. You are good at getting information across clearly, quicky.
I just discovered your channel and find myself watching every video that is suggested. This is quickly rising as my favorite RUclips channel. Thank you for making interesting intelligent and useful content
Dude, you do such a good job with this type of content.
If you're gonna generate a bunch of heat with electric heaters, why not put it to good use? Run a computer with a distributed computing project at several hundred watts. Computers do not consume electricity. They convert it to heat.
i don't consume alcohol, i convert it to burps.
Ethan M that didn’t work because the copper pipes used were totally bare with no insulation iirc, meaning that the the extensive piping in the room turned into a giant radiator and the computers simply heated the room. I’m convinced that if they’d just put some proper insulation on the pipes it’d worked out brilliantly
My very First HDTV wasnt as thin as the HDTV's you see today, it had a big grill along the top of the TV and heat would just constantly come out of it and so I used to just shut the door in my room and use the TV as the radiator. Warm enough air used to radiate from the back of the TV. Always kept the room warm.
the problem is you'll need to overclock to get it to work if intel/amd keep pushing the heat production envelope
@@Plair0ne It was more that "water cooling" doesn't really cool anything. Not in a PC, not in a car. It just uses the water to move the heat away from the device. It then requires an air cooler to cool the water. With the radiator in the same room as the PC, when you generate enough heat you need (as I believe they did) an air conditioner to move the heat outside.
He wasn't kidding in today's video about this one being old. Still great info though!

I use a heat pump in my home since 1998 !! Its a portuguese model and its really reliable!! Keep making good vídeos like this !! A fan from portugal !
I live in sweden, and we have no natural gas heating or whatever. We have mostly electrical heating, heat pumps or geothermal heating (or combinations of those), also many villas in rural areas have backup heating with wood burning furnace - many villas used to have oil burning furnaces before but not nowadays (think it was like banned or economically discouraged for environmental reasons or something).
But when the current WW3 enters it's hot phase, there will probably not be any electricity available, so would be nice to have alternative heating solution as backup, because heat pump, geothermal heating, direct electrical heating all relies on electricity to even work and I seriously doubt any average petrol or diesel generator would suffice.
Smart areas like your import tash to burn in a central heating grid.
Wood burning fire place
I don't know where you live, but in all of the Stockholm apartments I've lived in there has been district heating. But I'm guessing it's rare if you live in a single family house or in a rural area.
@@dijikstra8 Yea, but our district heating most of the time, if not all the time nowadays, get their heat from burning garbage. Not oil or gas.
Actually, here on the West Coast of Sweden there are a few buildings connected to gas pipes providing natural gas for heating. My friends house is connected to the gas network but he installed a heat pump instead. Cheaper in the long term...
The reason why heat pumps don't work particularly well in the winter is pretty much identical to the reason why some air conditioners don't work well on particularly hot days. A compression heat exchanger is limited to providing only a temperature difference, heating one side while simultaneously cooling the other. If either side approaches the operating temperature of the exchanger on that side, the ability for the exchanger to move heat will diminish until there is 0 or negative delta-t(in the latter case the heat exchanger would be transferring heat in the wrong direction despite its best efforts to the contrary).
Heat pumps which pump heat out of ground or ground water work pretty well at any air temperatures.
I use a geothermal heat pump as my main source for heating and I live damn near the arctic circle. Works like a dream
@@vladimirkoshelenko works pretty well, but for reference I spend less than 80 bucks a month on gas, which does my water and baseboard boiler heat in our house, and additionally have 100$ electric. Our folks have a cabin which has ground water heat pump which heats the house and the water and despite being a part time occupancy and usually heated to 66 when occupied and reduced to 60 when not has an electric bill of approximately 500$/month, this is because the units will use resistive heaters which BURN your cash. And this being an open loop pump and dump heat pump.
A heat pump will only use resistive heat 1) if the thermostat thinks it can’t keep up with the heating demand and 2) if a resistive heating element is used as the backup (or "emergency") heat source. The main reason why a ground- or water-source heat pump can’t meet demand is a very simple one: people go cheap and install the wrong size of unit. It sounds like your parents' cabin has a heat pump that is too small for the space and thus can’t heat it properly.
Another issue could be the thermostat. My Nest would call for the backup, resistive heat for no apparent reason (though I think it was because the temp wasn’t increasing as fast as the Nest wanted it to). So I disconnected it. My house needs a four-ton unit to supply 70% of the assessed heating needs (that's Canada's standard). I got a six-ton ground-source unit and supply 100% of my heating load, plus hot water, plus radiant heating in the driveway to melt snow and ice, plus heat the pool in summer and I can still be at about 85% if I add another storey to my home.
TLDR: your folks got a heat pump that’s too small and can’t meet the heating load of the cabin, or the thermostat is turning on the backup heat when it shouldn’t.
you may use a gas flame to heat the cold coil of the heat pump on cold days. This will improve cold weather performance. It is the Prius of heaters, a gas/electric hybrid.
I for one can say a heat pump is amazing for efficiency...I live in se missouri where it's not too cold in daytime but at night in winter it gets every bit as cold as it does in northern Ohio where I used to live. This thing has essentially paid for itself over the last 2 years we had it. When it gets really cold the electric heat comes on which costs an arm, leg and testicle. But that's only usually at night, as in day it rarely gets below 20 for a high temp.
I love this channel, this dude makes everything so easily understandable and he has an easy going voice that has the ability to calm even the most irate of souls, heh. Keep doing what ya doing, man, I love the videos!! :)
I would highly recommend a podcast! Even just taking audio from your videos itself would be incredible. Amazing videos and great presentation!
The province of Quebec in Canada gets 99% of its energy from renewables, and always has (hydroelectricity) and thus houses there only have electric heat, weather baseboard or forced air. Electricity has always been cheaper than gas and its more environmentally friendly because of this as well, so even though converting electricity to heat is a more inefficient method, it makes sense in this context.
When you live in a mountain area with 1 person on 1000 km2 it makes sense using "renewable" electricity from water sources. But another question is how to generate and supply power to cities in a flat area where population density is 100'000 times higher.
Quebec has a population of 8 million people with two cities of 4 million and 500,000 in their greater areas, meaning more than 50% of the province lives in a metropolitan area and the population density average of half the population is actually 4,517 people per square kilometer. They have no problem providing electricity and then some for these areas from hydro electricity. They sell a lot to the rest of canada and northern USA. 1,071 GWh was sold to areas outside quebec in 2016.
***** Well, I wouldn't call crowded a piece of land with a population density of 5.6 people per km2!!! The Netherlands have about a hundred times as much humans per square kilometer. Québec is a very abandoned piece of land on the globe.
You misunderstand. 50% of the population lives in the same density as the Netherlands. 5 million people live in an area as dense as Amsterdam or Rotterdam. While a lot of the land up north is very uninhabited, there is a small area that is very densely populated. The population of holland is 16 million, the population of quebec is 8 million, yet 99% of those people get their energy from hydroelectricity, and 50% live in large urban cities. You are making an assumption that based on population density, people actually live that evenly spaced apart. They do not. You can't look at the average. This is where half the people in Quebec live: www.cmhomestayagency.com/images/monti_ban.jpg. All those lights you see on? Powered by renewables.
rob mausser Maybe you misunderstood me. I would like to say that there are regions that have a natural advantage producing renewable energy, like Norway, Canada, Austria etc. And Quebec may have a concentration of population in its centres but has still a "back land" witch countries like the Netherlands, Belgium or Germany don't have. The energy plants can be far away from the centers. And so these countries have less problems calling them "ecological". It's not a merit of the population but due to mother nature.
Im glad the youtube algorithm also does some good things
alot of my favorite channels recently have been recommendations by the algorithm
I found this topic hot and it really warmed my soul.
I know this is an old upload, but I felt I had to add my two cents. I grew up in Minnesota in a house heated exclusively by baseboard electric heating. They built it in the late 70's when everyone was told, "Electricity will keep getting cheaper..." Yeah, it didn't. Energy companies are for-profit and didn't tolerate dropping prices. But my parents' house would have had to be completely revamped to add a furnace since there was no ductwork, and NatGas wasn't available anyway, so they kept the electric, much to their dismay, later discussed.
In order to power a whole-house baseboard, our house had 480v three phase coming into it. We had a huge 4'x3'x1' cabinet mounted to the basement wall that hummed all the time and said in big letters "DANGER! DO NOT ATTEMPT TO OPEN!" I was told it contained a secondary transformer to separate the phases for the house's regular needs. Deee-ammmn.
Now, the dismay. To keep a house warm in cold Minnesota winters with electric baseboard takes a LOT of electricity. In fact, if they had added turbine blades to the electric meter, with how fast that thing was spinning, that sucker could have made a trip to Japan and back every winter. Their power bill on cold months neared $400, A MONTH. I know because my dad complained quite loudly about it. For reference, that's like your electricity costing you $950 a month in today's money. It was bats--t crazy!
And our power bills haven't gone down these days in general, even though efficiency of lighting and appliances have gone up.
So, no, it's unlikely that we will see electric heated houses anytime soon again. The corporate complex will make sure the prices (and profits) stay too high for that. In fact, Xcel has raised rates for 4 out of the last 6 years here in Minnesota, each time feeding us a line on the hike flyer that "We haven't raised rates in x years." Lies.
I've literally never seen or even heard of a gas powered clothes dryer...
They have existed for a very long time... google it.. look at best buy even... they are common.

now your ignorance is cured.
Must be a U.S thing...
Even more rare is the gas powered refrigerators that the Amish use. They even have gas washing machines.
Gas powered refrigerators are also common in mobile homes. They can go a long time on a tank of propane.
This is the first time I've heard these being called a "heat pump". I've had a "reverse cycle air conditioner" for over 10 years - and it wasn't new when I moved in. It can switch between heating and cooling with a press of a remote-control button. My kitchen is 100% electric, and I don't even own/use a clothes dryer (hang clothes in the sun to dry). I live in Queensland Australia where the outside temperature virtually never goes below 0ºC. :)
The whole "400% efficiency" has always been fascinating to me, ever since I did a subject of fluid dynamics in a university engineering course around the year 2000 where we did some measuring of various refrigerative machines.
This channel is interesting, showing me different information than I might have otherwise.
Ben Hood My unit labels the outside condenser/ compressor unit as the heat pump though it works for heat and cooling because either way it's moving heat from one place to another
I'm just fascinated how things get different names in different parts of the world. I understand how this particular thing gets its names: from the mode it'll be more commonly used in.
I'm not entirely sure, but I believe that a heat pump (at least in Sweden) has the primary purpose of heating a room (or building) whereas a "reverse cycle air conditioner" can heat or cool said building. I note this as heat exchangers using air are usually sold as air conditioning, but when they are only meant for heating (like geothermal ones) they are sold as heat pumps. But this might only be a market sales distinction made for consumers and not any technical distinctions.
@Dracounius
This.
+Dracounius It's pretty much the same as the pretty much semantic difference between a motor and a generator which are both names for what is in essence two different operating modes of the same device. Though they may well be designed differently to optimise one function over the other I guess similar to how the blades are typically designed differently on an electric fan than a wind turbine.
I'll add this to the list of things to replace in my parents home. Thanks, TC
Thank you for sharing your learnings with us.
I've been working construction for quite a fair deal of time now, and I was under the impression that baseboard heaters were more or less phased out because they were so unfathomably expensive to run. They also had a horrendous habit of catching carpet and furniture on fire, due to their open element and poor airflow. There is a reason a lot of people who own old houses with baseboard heaters don't use their baseboard heaters. A more common replacement to baseboard heat, which has really taken off recently, and for good reason, is heat tape laid below tile flooring in kitchens and bathrooms.
or fluid heating pipes laid into a foam substrate under the flooring.
Other really, really, big advantage of natural gas is that it doesn't really go out. Unless you have like.. An earthquake or something.
In which case, all the other utilities will also be down.
Electric wiring is shit in some cities, where some bit of freezing kills the lines, and thus causes a power outage. Surprisingly, the water, and gas never seems to go out, ever. Hm, I wonder if burying the power lines is a good idea?!
@@mrbisshie Sounds about right...when the toilets freeze up and the power lines are down, somehow the telephones and gas still work.
@@VolcanoEarth It's exactly right. In my 56 years on this planet, Natural gas is the ONLY utility that has NEVER failed me. Literally EVER. Second would be "landline" telephone, That service is only in second place as we ONCE (way back in 1978!) lost phone service due to a downed telephone pole on out street.
@@CJT3X The possibility of what you say is exceedingly rare, However, Electrical faults cause (by far) more fatal house fires than problems related to natural gas.

4:00 soo, somewhere cold with a lot of non fossil electricity is good with electric heat, eg Quebec?
In Sweden we've been using heat pumps for decades. Air to air, air to water, water to water, earth heat, lake heat and heat from the earths crust. It's been done since I was a kid.
Even though a heat pump is less effective in the winter it can still be more effective than direct electricity even well below freezing.
I'm pretty sure you guys even have a system that recovers heat from sewage.
@@gregorymalchuk272 yes and also heat from the ventilation

TIL Humans invented the Sun.
I've lived in two different apartments with baseboard heating, and I can tell you with confidence that it is absolutely terrible at heating a home even when the units are new. It also makes the electric bill skyrocket in the winter. They're cheap and easy to install for the slum lords that put them in their properties though.
Yeah they are the most inefficient form of home heating by far.
I'm so lucky, seems I have the opposite system in my building! Every apartment complex building where I live has a big boiler in the basement which heats the entire building once it's turned on. Once winter starts and it gets cold enough, they turn the boilers on in each building, and that's it...all the apartments are heated until the cold season is over and the boilers are turned off (and the building as a whole retains the heat much better as well naturally).
You actually aren't allowed to even try to turn the heat below like 70°. You only have one option for your thermostat: turn up the heat to have more heat flow into your rooms...or don't. If it gets too hot for your liking, you have to open a window.
Which I've actually had to do. It's crazy, because I'm naturally a cold person, I've spent my entire life freezing 24/7 throughout winter, wearing jackets and wool socks in slippers inside, etc. and even have my awesome space heater here, but I've never had to turn it on once, because every room is basically equally heated (it helps that these are small apartments as well). I just run around barefoot too. The only days that my apartment gets hotter is hot humid summer days that are 80°+ with no cloud cover, resulting in my place being baked in the direct sunlight all day. Before I turn on the AC.
But yeah, the boiler system must have cost a lot to put in - fortunately it was installed from the ground up, many decades ago when the buildings were first built, so the greedy corporation that now owns all these buildings have incentive to simply keep maintaining the boiler system and eating the costs. I mean, not having to pay for heat is a huge incentive to sign a lease here in the first place. And the corporation employees don't really have to worry about the pipes freezing or any of the other consequences that can come from buildings getting too cold for too long in the winter.
So not only do I not have to pay for heat, but during winter my electricity bill is also dirt cheap, as it's only the electricity I naturally use. It then jumps up when I eventually have to run the air conditioning unit come summer, which is the biggest power hog. You can literally track how hot it got each month/day just by looking at my power bill for the past 5 years. 😆
Sorry for the rant, lol.
@@sorryifoldcomment8596
Interesting story. Never knew how big apartment buildings just use one heater.
@@42luke93 Yeah, it's this HUGE metal contraption in the basement. My building isn't that big, it's only 2 floors above ground (just really really long) so I actually don't know how the really tall buildings pull it off. I imagine once a building has enough floors, one big boiler in the basement couldn't pull off heating all the rooms.
But I'm not educated on that haha just know about the systems in the buildings I've lived in.
@@sorryifoldcomment8596
I looked into it and it seems that the city provides heat like with electricity. That’s why there is steam in the City. It has to get used or it gets wasted but that’s more efficient for big buildings.
All your videos are awesome, new and old.
My family has a vacation home in Northern Wisconsin. It's very drafty and almost impossible to stay warm during the winter. My dad hooked up a Franklin Wood Burning stove and that kept the house so much warmer then the electric heating system the house normally used.
Here in northwest Arkansas, I have had a taste of all the different heating types. Personally, gas heating is still my favorite because of cost and how well the systems seem to keep up with cold weather. My favorite though, is just having a nice wood burning stove. Yes, its best only in one room really, but I can deal with that because I sleep better in a cold room.
I'm 100% all about renewable sources for generating electricity..but I have yet to see an electric stove that compares to cooking on a good hot flame.
It cooks just as well, if not quite a bit slower.
Induction
You are amazing bro love your videos and the quality of information.
Here in FL we've used air-air heat pumps with backup electric heat strips as the HVAC standard for decades. The thing I'm chomping at the bit for is the geo-thermal component. That is still prohibitively expensive for most installations. But new inverter-based heat pumps have started to make in roads, too. They're much more efficient at lower outside temps; but are still expensive though.
TC: "I have faith that with the monstrous projects humanity has taken on in the past, we'll find a way around it."
Oil and Gas Companies: "hold my beer"
More like US consumer pocket books: Hold my beer.
They see the writing on the wall, and will continue to work for profit, even when it becomes profitable to ignore oil, of course. That's the goal, to make it better than oil economically.
Heat pumps have been popular in New Zealand for twenty years or so
I had an aunt who had a house built in the early '80s... in Texas. The suburb was an all-electric suburb. She had a heat pump. Even in Texas, that house was cold in the winter... and the heating bills were pure hell.
Great video and so well explained !
Having just watched all the more recent heat pump videos (2021) this feels like seeing an origin story.
A few comments:
1. Natural gas is so hilariously cheap compared to electric because it's a waste byproduct of oil extraction. We literally are not extracting the stuff on purpose. Don't believe me? NASA has that rather famous satellite picture of the United States at night. If you look at western North Dakota, you'll notice a huge blob of diffuse light, not pinpoint light that you'd expect to see from a city. Almost nobody lives there. What you're seeing are shale flares, with natural gas being burned off in quantities that can be seen from space, simply because we can't build the infrastructure to capture and contain it fast enough.
2. Efficiency is all fine and dandy for preaching the virtues of electrical heating but one thing you've essentially glossed over is the reliability of electrical transmission, especially in rural areas prone to inclement weather - gas, be it natgas pumped in from a public utility or propane from an exterior tank, is hilariously more reliable as a source of heating than electricity when the power goes out. You could conceivably heat your home in an emergency simply by turning on your gas stove or oven and light it off. Whereas if you're doing electric everything and the power goes out, you're screwed.
3. Again, with rural areas and inclement weather in mind, you can't rely on wind and solar to provide 100% of one's electrical needs. I live in North Idaho, and can tell you right now, in the winter, we get maybe eight hours of sunlight per day, it's overcast at best, and if you have solar panels, they're buried under at least three feet of snow. Wind? Only reliable in areas where it's actually consistently windy, so sure, you could probably convert the state of Wyoming into a gigantic wind farm but up here about the best we can do are gusts of 5-10mph, aside from the rare windstorm where it wouldn't matter anyways because the winds end up strong enough to blow down trees and utility poles.
To your first point, you're talking about associated natural gas. Non-associated gas, like shale and tight gas, makes up about 60% of the total US dry gas natural gas production in 2016 according to estimates by the EIA. Fracking is the main production method for non-associated gas, which has its own share of controversies (and I'm not going to weigh in on them here). It is cheap, however, because there's a lot of it in the US alone. (Even more in Russia.) Enough to last 86 years by 2015 usages, however, that makes a lot of assumptions. As more and more homes turn to natural gas because of its low cost, the less sustainable it will become. It's simple economics. It is, by definition, non-renewable, and so while natural gas is certainly in a boon now, just like oil it will be tested in time.
As for points two and three (which are relatively similar: not every place gets the same efficiency from power generators that rely on the elements), there's certainly truth to that. However, there's a few major counterpoints. The first is that our electrical grid can and does get better with time, and more investment is directly tied to consumer use of electricity. It's simple economics once more: Where there are profits, there is investments. Electricity transmission investments have grown by leaps and bounds since 1997, when it was at $2.7 billion, to $14.1 billion in 2012 (US, again from EIA estimates) and $21.5 billion in 2016 (EEI projections).
Similarly, the efficiency of solar energy technologies grows over time too, with today's record for mass production method viable panels reaching a record of around 26.6%. There's some big hurdles in raising the efficiency while keeping the cost down. With prices, however, the gains (or losses, depending on how you look at it) are even bigger. Solar panels are getting cheaper and cheaper over time and will get much cheaper once a larger portion of the population begins to adopt them and competition grows. Similar, batteries are getting larger and cheaper, so that eventually it's possible for solar to be viable even for places with eight hours of sun a day. Many panels are already more efficient in production of electricity than a house is liable to use in their daylight hours, so batteries can sustain that energy for a longer period of time. Some areas, such as in Southern Cali and in Vermont, are creating a storage solution to account for electricity disruption and to shave costs overall. Maybe it isn't viable everywhere today, but it will be viable some day.
That brings me to my final point, which is that what doesn't work for you doesn't mean it doesn't work for millions, if not billions, of people. No one is suggesting that we adopt a single solution and hope that it meets all needs. Certainly much of the US and other countries abroad are ready for this technology soon, if not now. More will adopt as the benefits get easier and easier to justify.
Point 2 was my first thought when watching this. Power outtages happen, but I've never even heard of the natural gas not working. When you live in the north and the power being out for days in the winter due to an ice storm is both a real and deadly possibility, you need the reliability of gas.
There is only one problem with gas .. it STILL needs ELECTRICITY to operate, as in water heaters, radiator or floor heating, since there are circulating MOTORS which run on ELECTRICITY .. not to mention the IGNITERS use ELECTRICITY. So unless you are running an old style gas range or oven, where you can light it with a MATCH, then not having electricity .. you are screwed anyway !!
Electrical heating works horribly evening it's efficient.
@@zoltangz That's why I have a deep cycle battery and an inverter-- to run the small electrical needs of my gas boiler, circ pumps, and gas water heater exhaust fan.
The basic reason why heat pumps are more efficient is simple: it is easier (less energy) to MOVE heat than to MAKE heat.
Also, the freezing problem has a simple answer. Place the outside coils underground where it does not freeze. This works everywhere from Arizona to the arctic, and has the added advantage that the outside unit needs no fan and makes no noise.
Alas, this obvious solution while used, is not that popular because many local governments suffer from severe head-stuck-in-posterior disease and don't generally permit such installations because they don't want to encourage deep digging (you might hit something).
Seems like you would run into a problem with the insulating nature of the dirt. Like it would work well until you have sucked the efficiently available heat out of the ground near your coil and then it would be slow for more heat to move into it.
outsider344 that is why they make (design) the coils very large to negate that effect. (If it is designed properly for worst case scenarios anyway)
Erbec Pickell
"Dirt is not insulative." It for sure is though. With an r value of up to R .5 per inch depending on the composition.
"It is insulative relative to some things, but only relative." This is true of all materials...
"It is considered an insulator because heat moves slowly through dirt" You don't say...
"When it comes to moving heat, it doesn't matter what materials you use. What is important is if the material can hold onto the heat." What is important is the conductivity of the material. Compared to the amount of heat needed for a house, the earth itself and the air in the atmosphere both have a functionally infinite amount of heat available. What matters is if you can get that heat to the exchanger to move that heat into the house.
"Of course, you need to make sure the house you are heating/cooling isn't too big for the spot of dirt. If your house is too big, you will eventually melt the dirt, boil the water, make the air into plasma." We aren't talking about using the heatsink material as a phase change cooler. It wouldn't make sense. Cooling a home by boiling off water would be a terrible idea unless the home was above 212F, much less ionizing gasses or melting dirt.
We are talking about heating by the way. Heating by using a heat pump as a more efficient method than by just generating heat. We are talking about burying the hot side coils of the heat pump underground because it stays about 70F a few feet down year round (because its insulated by the dirt above it). This would avoid the loss in efficiency caused by freezing air temperatures, but since you cant circulate in fresh dirt you run the risk of pulling all the heat out of the dirt surrounding your coil faster than it can be replenished by heat from the surrounding dirt. Unless you are planning to somehow super heat the dirt beforehand, the high amount of heat it could theoretically hold is irrelevant.
outsider344 and Erbec pickell you are both not listening to what I said about the size of the coils. A house, or any object loses, or conducts heat based on the area that heat transfer occurs across. A house loses heat at a certain rate based on the amount of insulation, the temperature difference, AND the area. The coils also conduct heat based on the insulation value of the dirt, the temperature difference, AND the area of the coils. Therefore, in heating mode, there has to be more heat transferred into the house than lost by the house, so you have to have more insulation in the house, and more area for heat transfer in the coils, and hopefully less temperature difference between the ground and the coils vs. the inside and outside of the house for most efficient operation. By having a large enough area in the coils for heat transfer, even if there is an insulative effect of the dirt, you can still transfer more heat into the coils than the house will lose through its insulation. All you have to do is increase the size of the coils if you need more heat from the ground. Just like any heat exchanger, in order to maximize heat transfer, you maximize heat transfer surface area. Hence why heat exchangers have fins.
Erbec Pickell it doesn't really store heat very well, because it doesn't have a very high specific heat capacity. It is because of the fact that as you move outward from the point of heat transfer, the area of heat transfer grows at the rate of 4 times pi times the square of the radius from the point of heat transfer. So the area grows exponentially, and so does the volume, so there is a super huge amount of mass that is available to supply the heat for the heat transfer.
(Almost) Half a million subscribers... well deserved.
Solar heating can be even more efficient if you don't use electricity as a medium.
For example a glass roof with a black floor - the house will heat up during the day, and stay warm at night if you close the curtains on the roof.
For more stable temperature, add "warm water tank". And of course you can still supplement with electric heat etc.
My next post apocalyptic sci-fi will start with "Yellow bow ties and grey skies"
Couldn't stop myself from making the jerkoff motion at "soon the grid will be 100% renewable"
Thank god you dropped the bowtie... and standing... and movement of hands, dry delivery, and - look, I'm just glad your style evolved. The current presentation makes your content even more enjoyable!
Thank you for these vids. I am going to patreon to follow you there
He says he's going to do a video about heat pumps in the future, but when I search I don't find one. Did it ever happen?
100 percent efficient? Someone is trying to murder the laws of thermodynamics here.
Because you're not CREATING energy, you're MOVING it. Sort of like how a gasoline truck is "300% efficient" if it burns 1 gallon gas for every three it brings to market.
This is interesting, I'm going to show this to my dad later, he's an engineer at my family's air conditioner firm.
1:45 Have this exact one. Kept it under my desk just for my feet.
I had an idea about electrical storage if we move to 80% renewable energy. 100% renewable is almost impossible simply because...well night and non windy days. Sure we have a few things like pumped storage hydroelectric. But even that can't cover all our needs.
But the question remains what to do when we simply create far too much electricity than the grid needs. Do days that is sunny and windy and not hot. So why not create HHO genrators?
HHO by itself is a terrible way to store energy. It is only 60% efficient and the gasses created are so volatile there are only so many things that can be done with them. But when the choice is to either save 60% or save nothing, the choice becomes easy. After all a system to set up such generators when the grid is hitting maximum capacity would be relatively easy as well as comparatively inexpensive. It would also be a good way to encourage the use of hydrogen fuel cell cars. Which in this case would be truly eco cars. And since at least part of the HHO created would otherwise be a waste product in the form of line loss, it seems an obvious solution.
Interesting how it really seems to depend where you live. Here in Ontario Canada almost all furnaces are gas, however the vast majority of stoves and dryers are electric.
I've honestly never seen a gas dryer, but for some reason my mom thinks gas stoves are better and always buys them
@@AwesomeSheep48 Well, that one is completely different. A dryer just uses the gas or electricity to heat up. A gas stove produces an actual flame, which allows for different cooking techniques. People "really into cooking" will most likely prefer a gas stove. You can't make fire while deglazing a pan with electric :)
I like your presentation. I like you. You never disappoint.
This is a fascinating take on renewable energy versus electricity. My apartment has hydronic heat (likely gas fired given the chimney above the utility room), and I have an electric space heater strategically placed for localized warmth on occasion, or to serve as a replacement in case the primary heat fails during the winter months. My local power utility (Idaho Power) has even gone so far as to produce a video series detailing the history of their company, including an era when The Electric House from being crazy cheap and economical to kinda expensive.
My mom has a gas furnace, electric dryer, and an electric stove. No, she ain't a pro chef, and it gets the job done just fine for household domestic cookery and baking.
There's one (minor drawback) thing you forgot to mention, @Technology Connections and that's that electric baseboard heaters can't have electrical cords or furniture smack dab in front of them, as they would then constitute a fire hazard (especially if the obstruction is made of wood) or a shock hazard if the PVC power cord were draped on top of the heater; that would melt the plastic and make the wiring in said power cord go "snap crackle pop" sooner or later.
Its not exactly 100 percent Electric heater elements glow ever so slightly Some is turned as light
But light turns back into heat when absorbed by surfaces. Besides (and probably more importantly), at normal temperatures, the light power given off is usually negligible compared to the usable heat.
Which, except for the tiny bit of visible light that goes out outside through a nearby window, gets absorbed and re-emitted as heat. So yes, it's probably *only* 99.9% efficient.
@@mattbartley2843 And sometimes a little buzz. But yet 99.9% efficient
@@longrunner258 you forget that the wire will create magnetic field which is loss, lol
@@pierreuntel1970 Magnetic fields are not a loss. They store energy and then release it back as electricity.
You might argue that the magnetic fields cause slight vibration and all that, but it's just heat in the end anyway.
Light given off as a glow escaping through windows is so small that 99.9% isn't even close to accurate. You need so many more decimal nines that it's pointless to bother with it. For another thing, the heating element needs direct line-of-sight to a window for that to happen at all. Even then, modern windows often block the transmission of the low-frequency infrared light that is given off quite well, so it's arguable that no direct loss actually occurs. Granted this next bit is my opinion, but when your loss is dozens of orders of magnitude smaller than your load, it's not worth mentioning, not even on a technicality, because its so small that it can't be quantified.
Woah, I had no idea gas powered clothes dryers existed. I've always had electric ones, and never seen a gas one in my entire life
How about a gas powered fridge?
They sell them at most big hardware stores
dlarge6502 the original refrigerator was an Electrolux but it used gas. BTW I always had a gas dryer. Only my newest dryer is electric.
@@dlarge6502 Most refrigerators in campers can run on electricity or propane.
They look & work just like the electric ones with an electric motor & controls. Just the heat source inside is gas. Everybody I know in the N.E. USA & S.E. Canada has one.
Nothing beats wood. We often get down to a humid -40c in winter where I live (heck, it's still november and it was -40 today) and wood does a great job at heating our big house. Plus, it's the most enviromentally friendly and renewable of recourses.
Wood creates so much negative pressure that it really is only good for one room. Also, no, wood is not environmentally friendly, trees are limited and it still releases CO2.
Such a strange and awkward channel. Yet, incredibly well written and compelling.

I've got a gas fired furnace from 58 and it's incredibly simple inside. only got 2 limit switches a gas valve and a 24V transformer. regarding what you said about heat pumps and automatically switching over to supplemental heat: on most central heat pump systems there is a resistive heating element that comes on when it's too cold for the heat pump or when the user puts the system in emergency heat. some systems will automatically turn it on to "help" the heat pump if the delta T inside is more than a few degree. on heat pump systems there is always a secondary heat source so in systems without resistive hest there is a gas furnace they operates in the same manner resistive heat does. this is necessary because when the hear pump goes into defrost mode it'd essentially going into air conditioning mode and without the secondary heat cold air will be blown into the living area.
Hey! Love your vids. You should create a playlist for climate control/AC vids, they're some of the ones I find myself sharing and rewatching the most often!
Thank you.
There is another reason why gas is even 'mandatory' in some case.
In canada, the rule of thumb is 10W per square feet of floor. A 30x40x3 floors (including basement) is then 30x40*3*10W = 36000W, or 150A@240V. A standard electric panel is 200A. Since the heaters don't work all the time it still leave enought power left for the remaing of the appliances. But a bigger house? You have two choices: multiple panels, or gas. Gas ends up a better solution...
Heatpump have another small issue: it do not work well or at all bellow about -20°C outside temperature. Also, the outside coil does freeze up, so it have to reverse the flow (go in cool mode) to heat up the outside coil to thraw the ice, then it turn on the outside fan to the max speed to blow away the water. Then it return to heating mode until the outside coil is too much iced up.
Heat pump can be about 300% efficient, but again, depend on the actual temperature on each sides. The greater the differential the less efficient it get.
thephantom1492 the outside coils only freeze up if they burried to shallow.
In the future probably some hundreds meters below the surface heat exchangers would probably become more common than laying them 10-20 meters below the ground, which needs a lot of excavating.
If you need a lot of heat over night, a hot water storage is probably wise to be combined with the heat pump, so it can buffer a lot of heat over the day, when not the full capacity is needed.
I can't relate to any of this, not much gas is used here. We have been warming many of our houses with renewable energy for a long time here in Finland; wood. I have never even seen a gas powered furnace or stove used in an apartment.
We have forests all around us, and we take good care of them by planting new saplings as we cut down trees. Some houses have oil burners to heat water and circulate that around the houses though, I suppose this is the most common way of heating larger buildings with multiple apartments. But at least here in north almost everyone has a fireplace of some sort to burn wood, and it's not uncommon to have a hybrid oil/wood burner that can use either resource to warm and circulate water around the house.
For stoves we use electricity, which in my case also comes from a renewable source, from a hydro-power plant.

Tiedätkös btw kuinka paljon Suomen energiasta tuotetaan uusiutuvin keinoin?
Aivan: 30 %
In smaller countries with a lot of resources, this makes sense. In areas like New York City, this is just not possible. Wood and gas fireplaces and some wood stoves are used in rural America for a homey feel in smaller quantities, however, these cause a lot more house fires compared to alternate methods. Personally, i like wood power but it is not fit in many cases such as cities .when it comes to renewable sources they are not foolproof. In order to harvest logs, a lot of fossil fuels (small in comparison to other methods) are burnt to cut and transport lumber. Hydropower hurts aquatic ecosystems and Nuclear is dangerous if it goes out of hand. Wind turbines are effective and don't disturb much. Solar panels are not good for the enviorment to produce. So, all in all, i think our current methods are working and i think electric is the way to go. Engineering renewable sources should continue if economically feasable.
With the possible exception of something like a pellet stove, wood is a terrible fuel. In the usual way that it's burned, it's really dirty, emitting toxic particulates and various nasty chemicals. These things are very bad for humans and other living things.
That bow tie kills me.

In the South we’ve primarily used heat pumps for decades.

Without heat strips too! It's quite , cost less than half to operate compared to a new'ish oil fired boiler and it's humidity control in the summer is unparraled. Most important is MOMMA LOVES IT.
Yes they do use a ton of electricity to run. It's like running your AC year round. Which is why they will never replace gas fired heat in the north. I have a propane fireplace and I run that most of the time to keep the house warm. Ambiance of a fire, copious amounts of heat, keeps the power bills down, and saves wear on that very expensive heat pump equipment.
Must be nice not having winter
@@cotton1983: Oh, we have winter alright. Heat pumps are equipped with electric heat as a backup for when the outside air is too cold for the heat pump to work.
"Picking Up Steam"
Pun facepalm.
Here in southern Brazil where we have mildly cold winters (in the range of 0 to 18 degree) and horrific hot summers (in the range of 25 to 40 degree) we normally use reversible air conditioning units that can operate as both an air conditioner and a heath pump
And yes, degrees are all in Celsius, not the nonsensical Fahrenheit bullcrap
This is a very good video. I had recently decided that mini split heat pumps are the way to go for HVAC. I recently found our about ductless clothes drying which use a heat pump. I still want my gas line because cooking with gas is so much better than electricity
Gas stoves are actually slower, which I find shocking but it's the truth.
Power lines go down a lot in winter storms. Gas stoves can be used with no electrical power to keep a house warm. Back ups and redundancy in cold climates are advised. The more of them you have the better. Gas, diesel, or a propane powered electrical generators, and a wood or pellet stoves are handy. It's also good to have enough food and water stored to last a week or two. You never know when the roads will be untraveled.
Good luck getting a chef (or just someone who cares about food) to use electric stoves
Yeah, we much prefer gas stoves over electric.
You ARE THE BEST
My house has a geothermal unit with a heat pump that is also tied in to a pair of water heaters. During the summer, the exhaust heat gets transferred to the water heaters, and it gets drawn from them during winter. Problem is, the heating system isn't that great on really cold days.
I even remember a time when the power was out for 3 days straight because a car knocked down a utility pole. The only heat source we had was the gas fireplace. We had a little fan connected to an old drill battery to blow hot air into the room.
Power outages are frequent enough in winter storms where I live that I’ll keep my gas power for a little while. I’ll switch when I can afford a backup generator
unless you have a steam system, or a gas fireplace, you need electricity to run a furnace blower or a water circulating pump on a boiler. Speaking of that, you can also install gas generators to provide electricity to your house in such cases
A gas furnace or water heater won’t work during a power failure as the blowers won’t be able to expel the carbon monoxide exhaust and you’d die.
Tiddlewink Muffinchucker My hot water heater uses no elec. and my furnace uses a tiny elec. pump to circ water and could be run by car batt. and inverter or the smallest gen set would do. Have lost power in single digit weather but have never ever lost gas flow. City water,sewer and gas with gen set keeps me happy. Huge gen set to produce elec for heat... why?...No thanks.

This is one of those things that i never thought would be so different in the us than it is in europe. We over here almost always have oil or gas powered central heating which transferrs the heat to the rooms via warm water and radiators in every room.
In our state, Natural gas is pretty plentiful, with some home owners having their own well on their property. It's all about costs vs. performance.

Also Me- oh, this shits 3 years ago, he done fixed it. Sorry, BruhBoo.
An often overlooked benefit of forced-air heating (gas furnaces, essentially) is that, in cold climates, homes often retain lots of moisture around cold surfaces such as windows and around doors. The warm air circulated by furnaces can help to keep humidity build up in these areas to a minimum.
That being said, i'm not for or against the use of gas- my ideal set up is a solar-powered DC mini-split heat-pump supplemented with a small wood stove.
Can you do a video on induction vs traditional electric cooktops
