Steps:
1. Standard electric dryers use electricity to power an element that heats the dryer to dry the clothes inside. The water, lint, and excess heat is then vented outside.
2. A heat pump dryer, on the other hand, uses refrigerant to catch the hot air from the dryer and that element is then pushed through a compressor to make it even hotter. That new hot air is then pushed back into the dryer and the cycle repeats itself.
3. Heat pump dryers don’t require vents, but they do need to drain. There’s a hose that can be run to a drain or there’s a built-in catch that collects water for up to two cycles before it needs to be dumped.
4. Heat pump dryers need 40-50% less energy than a standard electric dryer, though the operating time required for the heat pump dryer is slightly longer.

I'm here from the Technology Connections video on heat pumps.
Same :)
Yup me too!
Me too! Even Rich was talking like somebody who watched Technology Connections!
me too
Ironically, I'm not here after watching the Technology Connections video, but I've also seen that video.
I have a Bosch model that is pretty much identical to the unit Richard was demonstrating. I live in the UK (where most people don't have dryers at all) and the only laundry space was a lower-level utility room that would have been difficult, if not impossible, to vent to the outside. I was advised to go for the heat-pump model and I've been very glad I did.
Energy use is noticeably lower than with conventional dryers. There is a tiny bit more maintenance due to the need to empty the condensate tank and clean the heat-exchanger unit. Condensate pretty much every cycle. Heat-exchanger fins every couple months.
It doesn't make clothes as "crispy dry" as most Americans are used to. Even on the "very dry" setting, items like socks, towels, and sweatshirts need to spend some time in the handy "airing cupboards" most UK houses have. On the positive side, its probably not very good for your clothes to expose them to very high heat.
I was concerned about moisture build-up in the utility room. But there has been no problem in the 18 months I've been using it. I generally leave the door ajar, or run the overhead fan (the utility room doubles as a lower-level half bathroom.)
Overall I'm very happy with both the efficiency and operation of my Bosch heat-pump dryer. Especially when I see my neighbours trying to dry towels and bedsheets outside on a rainy, freezing, Sunday afternoon in February.
@@williamlyons3947 How do UK city dwellers (and others) dry their clothes when it's cold and wet outside?
Answer: Many people drape them over whatever horizontal fixtures they can find in their homes, including over the radiators that grace the interiors of most UK houses.
This, of course, creates other problems. Like rusting radiators, and a buildup of excessive humidity and condensation within the living space itself. To say nothing of the inconvenience of having unsightly masses of underwear, socks, and sheets hanging around the hallways, bedrooms, and living room.
It's not an ideal situation. But one that many (if not most) Brits seem to accept without too much complaint.
I will note that in the year since I originally commented, UK utility prices, including that for electricity, have more than trebled. A situation that makes Brits even less likely to use a domestic tumble dryer. Regardless, I still use mine for everything except dress shirts.
The untold story here is that a regular dryer that exhausts outside also has to bring the exact amount of outside air in. If it is 100deg out then that air is brought into the house, your AC then cools that hot air only to have the dryer heat it up again! Likewise if its cold out then you are bringing that amount of cold air in only to wast heated air to the outside.
Which is actually GOOD if you have ventilation problems in the home, get a co2 meter you will be surprised.
@@REALBanannamanI think you mean CO meter. As far as carbon monoxide is concerned you have a problem if you get any reading of significance . This also only applies to homes with gas. The other issue is when pulling a vacuum in your home you are bringing outside air in through all the wrong places (walls,attic,etc.) which is dirty air. If you want some fresh air get an air exchanger or open a window when the outside air is closest to desired inside temps.
@@mmaxx9915 I am purely speaking about CO2, you'd be suprised. Sealed homes with 5-6 people inside running around will raise those levels to 800ppm sometimes, enough to cause fatigue and brain fog.
@@REALBanannaman In that case get an HRV (heat recovering ventilation), your example shouldn't justify an ineficitient dryer.
@@lukasschmitz1799 That is dangerous. If the power goes out, your home turns into a slow killing chamber.
I just got a GE Washer/Dryer Combo which is only one unit. Never have to transfer the wash load to a dryer but goes into a drying cycle using a HEAT PUMP. I've had it now for 2 weeks and loving it!!
@fiat.freakx19 How has your combo unit held up over 6 months?
@kaknu been GREAT! Cleans clothes very well. Drying has been great also, i take out my cargo pants early as it tends to wrinkle them if i complete the dry cycle. Lint clean off about every third cycle. The app works ok, sometimes hard to connect but i find this common as with other appliances ive done this with. Overall this had been a great machine with no complaints or breakdowns. BUY ONE!!
Hahahaha. GE is actually haier. It will break in 6 mo. Then your warranty will be up and it'll keep breaking. Sell it now. We throw them away at work all the time. Juuuuunk.
Keep an eye on mold . FYI .
Had a Samsung unit in person in 2018 . The components continue to sweat for hours after use . Mold below the drum and in rear
Better description than other heat pump drier videos. Nice explanation and graphics. Amazing that it is more energy efficient, just takes longer to dry.
I bought the Miele W1 +T1 washer and dryer in May 2020, expecting the same perfect performance as my Miele dishwasher, but it has been a head banging experience from the start. It’s the dryer. The touch screen stops responding, so I can’t dry the clothes. I’ve had the Miele technician out twice. The first time, the technician said the dryer was fine, even though I told him the fault was intermittent. A week later, the dryer stopped altogether. Because of Covid, there is a 2-week wait for a service call. I dried my clothes on a portable line outside, while my $1,900 dryer stood inoperable. The 2nd tech replaced the touch pad control panel, and I had a month of trouble free drying. Today the touch screen stopped working again. I had to call Miele 3 times because I was disconnected after being placed on hold for extended periods of time. I asked for a new machine, and was told this was not possible until the 4th tech visit. Again I will be waiting 14 days before the tech can come out for the 3rd call. It has become clear that the only satisfaction I will get from this experience is taking a loss, buying a machine that works, and moving on. This seems to be the new Russian roulette of purchasing appliances, sometimes you win, and sometimes you get a hole in your head. I’m posting this to create a record for future buyers who want to make an informed purchase.
You know your getting old when a tumble dryer excites you
😂😂😂😂😂
Rich should make a segment dedicated to the different heat pumps for home usage:
1- Space conditioning
2- Heating water
3- Drying clothes
These together with an induction stove and a convection oven are the key to 100% home electrification.
except that induction cooktops suck
@@bigmikeobama5314 please explain this opinion because I've only ever heard positive things. They heat faster than gas, are more accurate and controllable than electric, the only negative i've ever heard is the initial cost
Live in the USA and have had a Bosch “ventless” dryer for the past 3 years. We love it. Just need to clean the condensation coils every few weeks, the heat temp is lower and power consumption has gone down. This also eliminates the issue of fires as found in traditional vented dryers. We will never go back to a vented dryer.
Excellent video, I have a Bosch Heat Pump dryer (which is excellent). This video explains the process much better than the literature that came with the dryer!
We got a Blomberg ventless, and it’s great. We got it as a stackable pair with the Blomberg 1600 rpm spin washer. This washer gets a lot more water out of the clothes than a normal washer due to the high speed spin. The dryer coils are protected by a second filter, which the dryer depicted in the video lacked. The water collected by the dryer goes out a hose into the same drain as the washer. We like this laundry pair very much.
@traybern With respect to your first question, we don’t buy something on that basis. If I wanted quick payback, I’d have gone to a sale of used laundromat equipment and bought a Speed Queen pair. Question #2, 2-3.
@traybern First of all, everybody makes his choices.
Second, about time, yes you can make 9 loads in a week. One everynight and two more in the weekend, it's easy.
Third. Lets have a family of 5 that makes five loads every week.
It will saves you around 2.5 Kwh per load = 12.5 Kwh per week X £0,3/Kwh (I live in UK) = £3.75 per week X 52 = £192 per year X 5 = £975 in five years. You can pay it and save the money to replace it or fix it if it brakes.
Oh!!! I forgot something, there are dryers with heat pump much cheaper, the cheapest in UK market right now is around £450
Absolutely fascinating. Thank you This Old House.
One of the better videos on how condensing washers work
Thank you
For anyone interested in getting one, I'd like to note that A+++ vs A++ vs A+ makes a huge difference, not only in terms of power usage but also time per cycle. An A+++ heat pump dryer can take approximately 3 hours for a cycle to finish. The higher the efficiency, the longer it takes to run a cycle. Keep that in mind, as I spent ages looking for an A+++ enery rating dryer only to realise the cycle was 160 minutes.
This only applies for appliances made for the EU market.
Yeah, I'm staying at a hotel in France for the next few weeks on business, and my only option is a Miele T1 heat pump dryer in the basement... it takes OVER 3 hours to get my clothes... damp. Not fully dry. (Cotton.) To be fair, it does a much better job with synthetics, only about 2 hours to get them completely dry. But cotton? Forget it. I just try to get them to damp, then I have to hang them over the towel dryer overnight, and that saves zero electricity there. It's just one giant heating element.
It's an interesting idea, but I don't see how the energy savings work if you have to run the dryer 3 times as long. :\ Maybe they'll get it right on the 2nd or 3rd generation?
@thomas seven i have no idea. i've tried cotton, takes 3 hours. i've tried express. takes 3 hours. no matter what setting i try, it takes 3 hours, and the clothes are never dry. the *most* annoying part is that it uses its little "dryness sensor" to tell me, "oh, this will take 1:12 to dry!" i go up 3 flights of stairs, come back down, and the clock now says, "oh, did i say 1:12? i'm adding another 1:20!" then i come back, and it says, "oh, did i say another 1:20? i meant another 0:26!" then it finishes, and it's damp. i try running it again, it runs for 26 minutes, and its *still* damp. compared to my US dryer, i dump my clothes in, 50 minutes later on the lowest possible setting, and they're done and dry. maybe it's a faulty unit, i dunno. but my experience has not been great.
on the upside, going up and down 3 flights of stairs repeatedly has done wonders for my quads!
@@ughtentide I wonder if the filters need cleaning - that would explain it's predictions being out too.
thomas seven ,
How big of a load can you do? I was about 15 shirts at a time, and I am still buried in laundry, so if I have to half that, then I really will be in over my head.
Recently bought a heat pump dryer,much cheapet to run and does a good job.
I have 2 of these Heat Pump Samsung dryers (since I have an oversized Samsung Washing machine) and I loveeeee this machine!!!! Dries very quickly, Super efficient, no humid hot air, just a bunch of water is pushed out, and it's very quiet. More companies should be making these!
Why 2 Samsung heat pump dryers. & if u say it dries what model have u please
@@maureenmcelholum1280 same model as this one. DV22N6850HX/A2. I got 2 since the washing machine I have is 2x the size in order to match output
@mrgylex123
?
Love the videos...entertaining and educational...keep 'em coming!
Excellent video, truly practical, informative, and helpful.
this is actually really cool. a fantastic example of using known technology in innovative ways.
I bought a Whirlpool model very similar to this one. $138 during Fred's going out of business sale! It takes it's sweet time drying, but it's very energy efficient. I've had it for about 3 months, and I'm happy with it.
There are two types of vent less dryers. Most of them are what we call condenser dryers. They not only take forever (2, or 4 hours). And many (most) models run cold water through the condenser for cooling and then sends the water out to a drain (they thus need a water drain).
As a result you use LOT of water to dry your clothes.
Then there is the REAL heat pump dryers. These units are expensive and have built in heat pump to run the condenser (the same as an air-condition unit).
Heat pump dryers don’t use water for cooling, and they are at least 2 if not 3 or even 4 times faster than condenser dryers. So in place of 4 hours, a heat pump dryer will take about 1 hour.
So a typical heat dryer might be 30 minutes, the heat pump dryer would be about 1 hour.
A condenser dryer? 3-4 hours! (And it using water for cooling). (We talking gallons of water here). And your clothes is still not really that dry!
A vent less condenser dryer is often smaller, and is often a “combo” washer dryer.
So, a “combo” washer and “condenser” dryer unit might set you back about $850 dollars. (Some are even cheaper).
A condenser only dryer? They go for as cheap as $500 or even a bit less.
The real deal Heat pump dryers? The ones with a real fridge unit (aka: heat pump inside)? They are rarely combo units, and they start close to the $1,000 range for JUST the dryer. And you can easily pay $2,000 for some of these units (not a combo unit).
Most heat pump dryers also have a heating element, and if you put the unit on max, it will work as traditional dryers in terms of time. (you same some energy however, since once temperatures are up, then the heat pump running provides a good deal of the heat required. These units thus can run and use their heating element, or just the heat pump only in a cycle to dry (or a bit of both). They are vent less, and have a water collector, or optional can use a drain.
But the condensing process for these heat pump dryers work far better because you have a real heat pump running the condenser unit to pull water out of the air. They cause much less wear and tear on clothes, since it not heat that does most of the drying, but a condenser that pulling out moisture.
Those lower cost “condenser” dryers as noted tend to be combo units - and they tend to increase humidity in the dryer room.
A heat pump unit does a MUCH better job of removing moisture because there is essentially an air condition unit inside of the unit for the condensing process.
The energy savings of 50% compared to a regular dryer is due to the unit recycling the hot air to cold and then back around to the hot side (it’s like leaving your fridge door open - it will not cool (or heat) you house that way!!
So the room is not heated up much in this mode. And you not sucking large volumes of air from the room to the dryer and then heating the air and THEN venting it outside. That is air you paid to heat, or paid good money to cool.
The 50% rated savings in energy does NOT include this significant factor of using large volumes of air and then venting that air outside.
Condenser only dryers (without heat pumps) are also vent less, but they SUCK big time. They take hours and hours. They tend to be cheap as dirt, and as noted most use cold water flowing through the condenser unit and then that water is sent out to the drain. (Gallons of water are thus used to dry your clothes).
The difference between vent less “condenser” dryers and vent less heat pump condenser dryers is night and day (and so is the price!!).
So heat pump dryers take about double the time compared to heat dryers, and this will somewhat depend on what energy mode you run the unit. If you run them at full mode, they will work quite much like a regular dryer (but is vent less).
Those rotten condenser dryers as you note take 3 or even 4 hours - and your clothes still don’t come out really dry.
@@Albertkallal Thanks for the info. The dryer I bought is a heat pump dryer. Model# WHD5090GW This model normally retails for $1100-$1200. I just got lucky!
Albertkallal I have never seen a condenser dryer that uses water as a coolant- is that a US thing? Condensers are probably the biggest sellers in Europe, and none of them have ever used water. Are you thinking of the combined washer dryers which sometimes do?
I just moved into a house with one of these and this was very helpful to know. I couldn’t find an exhaust anywhere and wasn’t sure why haha.
I have a new Meile t1 dryer and I like it. If You are used to a huge gas dryer with clothes from a family of like five you’re not going to like it. These are smaller dryers and you have to get used to it they do work a little differently you cannot do huge loads but eventually you get to learn what cycles/ options work best. Remember these are meant to fit where your dishwasher goes. Rich people have them in their yachts. These are excellent solutions if you’re a renter and there is not proper electric for a traditional dryer hook up and nowhere to vent it! 110% better than going to the laundry mat. Also keep in mind this is the way of the future machines will work this way so get used to it there efficient and safe! I would say the load size is no more than what you would consider a medium load in a full-size washer
That could be a problem when I wash my thick comforter.. it barely fits in my full size vented dryer. I guess I'd have to dry it outside on a clothesline if I had one of these.
So if your washing machine was 7kg, what size drum on a dryer would you recommend people consider for a full load.
Just arriving now?? I've been using a heat pump based dryer for more than 5 years now.
Just got an LG heat pump and it's incredible. We're using less than half the energy we did before - and we aren't pushing conditioned air out of our house!
I have this exact model. The thing is crazy efficient. Like half a kWh per drying cycle. I run about 2 loads a week for myself (it's a smaller than normal sized unit) and running this thing with my 14 cents per kWh electricity it's less than $15 for the whole year of clothes drying.
How long does it take to dry clothes though like with the whole thing mostly full? Also, how dry are the clothes when they are finished?
@@Fusiongearz about 1.5-2 hours depending on how jam packed it is. They're completely dry when they come out.
This video is SO GOOD!! (Side note, I think a downside of this "keeping the hot air locked inside", struggles to 100% dry the clothes.. always a tad of moisture that can't be squeezed out... doesn't leave the clothes hot and toasty and dry like a normal dryer.)
Nice and cool appliance! Can’t wait to get one ☝️
And they are great, we had ours since 2018 and its reduced our cost clothes dry nicer they do not,stick together there no static there no over drying the water container will last up to 4 loads
I love my heat pump dryer. It maybe takes like twice as long as normal if you fill it full of wet towels, but other than that you don't notice. That isn't even the point. It is super quiet, and i mean super quiet. The clothes are hot and very dry when they come out, and they are not TOO hot. I"m sure the clothes benefit. It doesn't pull air into the house, but it does get warm, and i mean like lukewarm. so that might be beneficial. I hooked it up to the drain first thing. I checked my energy monitor, and sure enough, instead of 8000 kw, my whole house WITH the dryer running was only 1400 watts. When i picked it up, the guy said you know this is ventless right? and I told him I came there specifically for that dryer. He said it was a pretty niche commodity, and I thought, you don't even know.
I have one. It's awesome.
These have been standard in Norway for a decade now😁 and mine looks almost like this pne shown. Its a great dryer!
Er det virkelig sant
Yep, and thanks to the internet exposure some well kept secrets such as low tech USA could be noticed in the cyber space.
Can you explain what you connect the drain hose to?
@@aortunoj A drain.
How long to dry an average size load? I would say a week’s worth of clothes for me with a conventional dryer would take about 45 minutes to an hour to dry.
that's really really great engineering
I've owned a Japanese model for ten years. The cost of electricity for every cycle is about 10 cents USD.
What do you have? I'm curious.
Yes what is the make and model?
@@Smurdle450 ruclips.net/video/pvGp_3iFvS4/видео.html similar to this one
@@icie4u It's a Panasonic. I don't remember t he model.
We've had these in Scandinavia as well for many, many years. And our electricity cost is typically cheaper than in the US, but these are still a a no-brainer
Very helpful.
Would love a Vid on a AC DC ductless mini split. Uses power from solar panels but also uses power from the grid when needed. Are these viable? How does the cost compare?
This is such smart and efficient engineering, it solves all the problems and tasks of a dryer efficiently and all at the same time. It uses less power, heats the air with over 100% efficiency and pulls the moisture out of the air by condensing on the "waste cold" end. The only way it could make this better is by automatically dumping the water pulled from the clothes into the washing machine to be reused. This is arguably a more phenomenal use of a heat pump than for regular temperature management in AC and home heating.
I’d rather not reuse the water I just washed my clothes with…
@@johncaccioppo1142 not even to flush your toilet or water your yard?
@@graysonsmith7031 Flush water, yes, yard, no. Definitely not to re-wash my clothes.
I also should mention I assumed this unit he was talking about was an older Meile. There are brands to make a bigger heat pump dryer that plug into 220 the Meile is working only on a standard outlet which makes a difference as well.
Hi, do you have any feedback on Meile 110 ventless dryer? Thanks
@@bennisim7949 I have one Miele (BTW not Meile) and it has performed beautifully, it runs on 110 and I capped my outside vent, it shares the clothes washer drain to get rid of the water. It tells you when the filter has to be cleaned. Beautiful machine, a bit costly but you get what you pay for. It's smaller than a full size machine but handles about the same quantity of clothes. You can put a freshener cartridge that gives a nice smell to clothes dried in the machine, not those cheap perfumes used in the Bounce type additives.
Wetrock thank you for your reply. I actually bought one and really like it.
Thank you! I’m living on my own away from family. My apartment complex isn’t great or fast at fixing things. I thought my dryer was broken because it wouldn’t dry my clothes. I learned that the holding tank for the water was full and had no where to go!
that is a genious idea
@2:50 Not arguing with efficiency but cycle *ABSOLUTELY* takes longer. 2-3x a traditional vented system. And very few full size unit options.
Laundry day will actually take an entire day!
Very interesting.
Awesome
ive owned one of these for about 2 and 1/2 years it's fantastic and way cheaper to run, i got it because i have 11KW solar system so i run this thing for free
Whats the watts used per hour
@@frankmundo4300 mine is 600watts
Another advantage is that it doesn't pump conditioned air outside the house. Best place for a standard dryer is the garage or basement for this reason.
Lint buildup in vents is a leading cause of house fires so that’s another benefit to this unvented unit.
You still have to clean filters of lint though
Just do it every cycle 👍
Not to mention those leaky tub type that use a felt gasket to blow lint through your house.
@@eaamonmangan4601 it would never blow into the house it is contained inside until the user cleans it out
@@stephensnell1379 yes Steven that was my point. heat pump ,the dryer is fully self contained. the older drum types are not they use felt gaskets that leak lint into homes. the felt gaskets are mounted on the tub's edges attached to plastic holders. they break or get worn out and interior pressure blows lint through out peoples homes. good for selling vacuums to those that owned them.
Saw these in use in Germany... 11 years ago.
When it’s runnin then it’s spikin
Just arriving!!! We have had this for ages in Australia
This is America! Get out of the way of my Escalade! We've got fossil fuels to burn dammit
I don’t understand why u guys are so behind everyone has switched to metric and u guys are still using imperial also why do u use dryers when it’s really hot outside u could just hang them out which is free
@@maxd4968 Hey, there are 5,280 feet or 63,360 inches in each of our miles, just like god intended! Joking aside, many people don't live where you can hang clothes out to dry. I certainly can't in my apartment. There are also areas where, while hot, it's also so humid that clothes won't dry and will likely develop mildew. My parents, who hang clothes out to dry when possible, also have to work around heavy pollen, which will leave a yellow tint on clothes for a good part of the year. In the southwest where it's hot and dry the sun is so intense it will quickly break down and destroy fabrics. Most of us don't have a choice but to use dryers.
I live in wa (Western Australia) and I don’t even have a dryer since it is always in the 20s or 30s Celsius’s (70 to 100) even when it’s raining we just put then under the patio and there dry within a few hours
jblyon2 Too hot and dry to sry outside?! That has to be the most American thing I ever heard- and not in a good way. No wonder Americans are the biggest energy users and largest carbon emitters per person on the entire planet. Yes, I get you point about sunlight on clothes but either don't leave them out all day, or hang them under the porch or some kind of shade out of direct sunlight! Sorry, but dryers in that climate are nothing but laziness.
I like living where “condensation” is not a factor, or is in the beneficent side, like the passive swamp cooler method.
Wonder if he will talk about heat pump boosting through geothermal, solar capture or both working in concert.
We've had these in Europe for years. Critical in old buildings where you can't vent the dryer outside. Also known as "Condensing Dryers". There is a practical limit to the size they can be; at some point you get to a point where it's not efficient enough to dry a very large load of clothes, you are forced to dry smaller quantity of clothes in one go. Which works since the washing machines are also correspondingly smaller, you can't fit a metric ton of clothes into the washers here like you can do in the US with other front-loading washers. All in all, they work well enough.
Josh Payne condensing dryers is one thing, those have been around since the 80:s, maybe even earlier. Heat pump dryers is the next step in the evolution of dryers. They became popular around 2010 here in Sweden. Don’t know about rest of Europe. But it is sad to hear that it took America another 10 years to discover it 😔
@@BigJ2020 Sad indeed. I bought my first heat pump dryer 15 years ago. Instead of 2kW it consumed only 0,5kW. On that model I had to manually clean the heat exchanger once a month. My current heat pump dryer from 2015 uses the condensed water to rinse the exchanger and flush out the fluff automatically.
@@BigJ2020 trust me, there are still going to be Americans who refuse to switch to these despite the advantages.
So instead of doing one large load of clothes we'd have to do two small loads with this one. There goes all the savings!
My point above is proven.
read Fons’ comment. Power usage went down from 2 kw per cycle down to 0.5 kw, so even if you had to run 2 loads, you’d still be at 1KW, so you’re STILL saving energy.
Good video
We've been using heat-pump dryers in Europe for years.... We bought an Electrolux 6 years ago... Never wanna switch back to conventional electric dryer. It saves us a lot and good for the environment. Here the new slogan is Be-Eco
This is ingenious. I just saw how much electricity my dryer is using with a new electricity monitor, and it’s insane.
Why isn’t anyone comparing it to a dehumidifier? That’s a better analogy than an air conditioner or refrigerator.
Dehumidifiers do create a little extra heat that goes into the room, and this machine would do the same (energy cannot be created nor destroyed). That’s good in the winter, but I have a solution for summer. If you also have a heat pump water heater, locate it in the same room. That would recover the waste heat and put it right back into your hot water!
From my perspective, these driers are more analogous to dehumidifiers. My drier doesn't run that hot, but rather feeds the drum with air that the moisture gets stripped out over the cold evaporator. That water is then used to wash the fluff off the condenser periodically. Complete genius.
I know they are already building heat pump climate control systems with a condenser, evaporator, and third condenser for water heating, and juggling the load between them. I doubt we will see the levels of home integration necessary to plug the dryer into the refrigerant lines, but I feel you. Actually, that accumulated compressor work waste heat could be a problem if it isn't dumped to the room air. The recirculated dryer air would eventually get so hot that the evaporator couldn't get it below the dew point, and the head pressure in the condenser would rise until the compressor tripped out or melted down.
That's what I was thinking.
Summer: vent the tumbler dryer into the room, have the heat pump water heater suck in the hot air, turn it into heating source for the hot water, plus cool the room.
Winter: do same action as summer.
What's there to lose? Someone correct me, in simple terms
Heat pumps have 300+% efficiency. No, they don't brake energy's laws.
They don't make heat, they condense and transfer heat. That's why they can't catch boiling temps and they need more time for the same work.
Yes, I just measured the amount of electricity to run a standard electric vented dryer today and it was around 5-6 kWh per load. I couldn't believe how much 6 shirts and 6 pairs of shorts cost, at $0.18 per kWh that's over $1.00 per load. A large family home may decrease their energy needs significantly using a heat pump dryer unit.
Btw - When it comes to using a heat pump water heater, I believe these may not work well in colder climates (efficiency wise). Water heater heat pumps remove heat from the surrounding air, the same air that may have been heated by the home heating system. I think the water heater pump units work best in places where an A/C system is running all year. In example, a water heat pump may work great in South Florida, unless if the cold coils collect condensed water and have no where to drain it.
This would be great in the RV and boating industry.
i guess it also includes an element of safety as there is no glowing red hot coil just some cold and warm copper pipes
You are dumb
If you clearly listened it mentions heat pump dryers use a refrigerant
Actually you are dumb - read the comment again lol it has hot and cold copper pipes and no glowing coil
This would be great for apartment complexes. Now all you need to do is make this into a combo washer dryer all in one. This way you would hook a hot and cool line up to it and a drain line and it would take up less space in a small place.
LG makes an All-in-one washer dryer unit which I've owned for about 8 months now and it works great for small less frequent loads of laundry for people living in apartments with no washer dryer hookups. The only downer is it takes 2 1/2 to 3 hours to do one load
I put the LG combo units in my rentals. They work great
Stacked washers/Dryers…
It was a good video but I did have to laugh at the comment you bought for your wife. I bet she loved that gift to use.😂
My sister has a Bosh heat pump dryer and she hates it. First is that it is tiny. Second that it takes over 2.5 hours to dry and it is not as dry even then than what a gas or electric heater one can do. If you don't ever has much laundry to do, it will be ok but if you have a family forget about it. I would only get one of these if I was stuck in a place that could not have an exhaust.
2.5 hours to dry! My god I can run my washer, dryer, fold the toasty dry clothes and still have an hour to spare. Meanwhile these heat pump units will be taking out damp clothes that they have to air dry after briefly.
Heat pumps for everything haha
Great vid! I have one question.. Can i place a thermo pump dryer in a laundry room where there isnt a very good air Flow? In time the air in the room will get hotter.. will this make the condensing stage harder..? Looking forward to your response. Thank you in advance.
Makes the room a little warmer due the the efficiency loss in the HP. Doesn't affect the drying time.
I assume these things have to eventually start dumping the compressor work heat to the room air, or the recirculated dryer air would eventually get so hot that the evaporator couldn't get it below the dew point, and head pressure would rise and the compressor would trip out on safety. I would think any room big enough to fit the dryer in would be sufficient.
It isn't just the 50 percent reduction in power consumption on the appliance itself; it's also less waste heat overheating your home in the summer, and no more sucking air out of your home that you've already paid and used energy to heat or cool. So major savings there too for your pocketbook and the environment. And, if you're using a device like this to replace an older ventless dryer (e.g. washer-dryer combo or ventless dryer) that uses a condenser, it gets even better, because you're no longer using many, many gallons of water to run the heat exchanger; you're doing it far more efficiently and quietly with refrigerant on a closed loop.
whats the difference between Hybrid Heat Pump and Heat Pump? is it just the power consumption?
Hey Rich! What do you think of 2-in-1 washer dryer combo, specifically the new GE profile?
They've had these in the UK for a while, they work great.
One issue on condensing dryers, is that if they're in a closet, the closet has to be open during operation. Conventional dryers remove air, so there's always fresh air coming into a closed closet. With a condensing dryer, on the other hand, there's no exhaust airflow, and you're still putting a lot of energy into a small space. It'll make your closet heat up until the dryer shuts down from overheat.
This has an air conditioner
@@AgentOffice Try putting a portable air conditioner in a sealed room. Air conditioners move heat; they're incapable of deleting heat, since that would break the laws of thermodynamics. In the process of moving heat, they also generate a significant amount of waste heat. Since you're just moving heat from one part of the room to the other, plus adding waste heat, the room will heat up rapidly.
basically a room dehumidifier, and, if this was done under a vacuum, it would be an even more efficient cycle. lower the ambient air pressure in the drum and it would dry faster.
What about a This-Old-House video on combination washer/dryers ??
Topics: Technologies used, installation limitations, how to fit one into a small area (or closet) ...
Thanks for featuring the Miele anywhere dryer!
Interesting.......
Someone needs to design a whole home energy management system that shares energy between every appliance along with ventilation systems.
For entertainment? Surely the cost would outweigh the cost savings.
In a tight house it solves the problem of makeup air after the dryer pumps out a huge amount of air it must come in from someplace and it may not be conditioned also the risk of de pressurization and possible back drafting of combustion appliances
Building codes state makeup air isn’t needed unless your blower is over 400cfm and a 4” circular dryer vent maxes out at 400cfm so it’s an impossible issue you are trying to solve for.
Just realised how much I would save on the running cost with one of these as the U.K. energy prices are through the roof ~£0.35/kWh. New machine would pay for itself in a couple years! 100% worth it!
It saves around 70p per cycle. If you have two cycles every week you will save around £70 every year.
Can I ask question. Do we have to vent electric portable dryer if we spin dry or wana just use as wrinkle remover or just to fluff clothes my clothes come out my washer almost dry do I still need to vent. I ask cause I don't have windows that open in my kitchen area I only have sliding door but I would need open whole screen also to vent n there is no outlet near it:(
What about wrinkles, and if you left them in the dryer for a day, how fast can you get rid of wrinkles.
In one video you used a heat generated by the central air conditioner to heat a swimming pool. Extrapolating on that how about used a heat output from your air conditioner to dry your clothes. I can see a DY I rule-Goldberg device that would probably work quite well on a hot day, of course you could also just use a clothesline. Samsung H.P. dryer runs 900.+ that's a lot of quarters for the laundromat.
I think what we all are forgetting is that is is new technology to the dryer industry/users. Like anything else there'll be improvements. Remember how the new front loader washing machines had some problems. The industry will either enhance it or fade it out.
larry moore Front load washing machines have been pretty much the only ones used in Europe for forty years. Nobody has used a top load since the seventies. I don't know why Americans are so against them, or think they are new? They wash better, use less water and energy, damage clothes less and spin much faster meaning clothes dry faster.
Thanks for letting us know there is a ventless heat pump dryer available. Great unit for those who can not vent directly to the outside. However... the most complaints about these type of dryers is that they do not get the clothes dry. Either they are damp (too damp?) or they take 2 to 3 hours to dry. What would be informative is a break down of the energy cost comparison for an average load of clothes. So say how much, at full heating, will a vented electric dryer cost compared to full heating (if there is a setting) for the heat-pump dryer. So from the reviews I would say 45 minutes for a conventional dryer at full heat to a 2 hour with the heat pump unit and compare the amount of power each used. Also include how much each useds (at full power) for one hour so the common person can do their own comparisons.
If you have a full basement I would suggest using a good dehumidifier and hangs your clothes in the basement. Would save a whole lot more electricity and money that way. Need to fluff your clothes? Hang them outside and let the wind naturally, and freely, fluff and dry your clothes.
HugeWolf1 In Europe All appliances come with an energy label detailing exactly how much they will use. For dryers it shows the energy required to dry a standardised load, usually 5kg of cotton from a certain saturation to another set point of residual moisture. So one can easily compare. Heat pumps are much slower but use a few hundred watts rather than 2-3kw, so even taking into account the longer run times they still use less overall.
@@spencerwilton5831 they're also much more gentle on the clothes, less heat, no scorched or shrunk clothing.
@Hugewolf1 and others, have a look at this guys energy usage comparison between a heat pump and conventional vented clothes dryer. We're yet to decide on what we'll upgrade to, but this comparo has helped.

I have whirlpool dryer. Heat is working but air doesn’t go through so all clothes stay wet but dryer itself become very hot 🥵. Even whole body such a hot can’t touch more over in the drum extremely hot. Drum also doesn’t spin.
Please guide me
I didnt noe how nd electric dryer worked til i took it apart i was looking 4 da heating element dan i found itz just like a toster
My 9 kilogram LG Hybrid Heat-pump dryer is cheaper to run than my washer. The newer ones are pretty good. Plus all the waste water goes into the vegie garden so no water is wasted.
Dan Cunningham ,
Are you sure that's ok? Personally, I don't see why not, but my dehumidifier's instructions say not to use the water in the garden.
@@bigred9428 The lawyers made them say that.
Tom Cartmel ,
If I had the money, I would be sending EVERYTHING to a lab, including this waste water. That way I would know what's what. BTW, I am pretty sure it only says veggie gardens. I should have specified.
@@bigred9428 I believe you may be correct. The water draining from a heat pump dryer would not be clean and may be considered to be gray water, which needs to be treated in a septic system same as the water from a clothe washer.
Whats the cost of running a natural gas clothes dryer compared to this and whats the difference in drying time??., also heat pumps are usually more complex and expensive too fix, and with my experience a washer drier usually needed some sort of repair within Five years.
this tech has been out since 2001 at least. I have a washer/dryer all in one unit that does that.
Great video how much for this dryer?
I have the Whirlpool equivalent, and it was over $1000.
And how long this will work before is all clogged up? I can cut consumption by a hundred% by close line. Someone here says it has one for ten years that's surprising, maybe I shouldn't be so skeptical.
So they basically combine a dehumidifier and a dryer?
skmetal7 more like an a/c unit, it has Freon in the system
Like a dehumidifier in a closet.
Basically, yes.
had that model now for 3 years -mistake because you can not clean or remove to clean the botton vent properly (wet lint ) machine is not drying properly now
Yea this is a huge flaw in the design. The genius of vented dryers is that lint is blown outside or gets trapped in up to a 25ft vent. I clean my dryer and dryer vent for lint every 3 months. Knowing all the lint my clothes produce with 8 pets I’d kill this machine in a year through lint alone.
Though I love the concept, combining a dryer with a refrigerator seems it might create a whole number of things to go wrong?
Overcomplicating something that should be really simple.I'll pass.
They are seriously awesome. Don't knock it until you buy one.
I have one. They work. Just like a refrigerator or air conditioning system is built to last decades, so is my Míele heat pump clothes dryer. Plugs into a standard outlet (240V not required) and drains right down the same pipe as the washing machine I have below it. I closed off my vent from my old gas dryer. The new machine saves money and is more durable and better built than my old gas dryer which vented to the roof.
And, it runs on 120v outlet!
Why not combine it with the washer?
Can this be hooked up to the ground sourced heat pump systems?
No, this system is closed loop. Removing the heat or cold from it would render it ineffective.
What brand was this?
for PEOPLE who actually used one for more than 3 months, could you tell me how long does it take to actually dry a normal load of cotton and your machine year? I used a bosch in 2013 when i was in an apartment, but I thought that thing was broken. Wanna know if there is any improvement?
I’m wondering if the coils were super clogged? I can almost guarantee I would miss the coil cleaning step if i didn’t know that this was a special dryer
Have used European combined washer and condensation dryer unit. Have to say the drying experience is not that great. This heat exchanger dryer is along the same line. Have to wait and see.
You might have a condenser dryer. Not as efficient
I think it'll be pretty awesome if they came out with a heat pump oven.
Five weeks to cook the Thanksgiving turkey
@@Viper81766 yep. It'll probably go bad before Thanksgiving.
How much will it cost and how long will it last to get a return on investment??? I dump my dryer vent into my 120-year-old house to get extra heat and moisture. Have done so for 25 years and its great to keep house from being all dried out. FYI it is an electric dryer, not gas.
Yeah, if it was gas, you’d not be around much. I had an electric dryer that had “no vent” in the UK in the 90’s. I’m pretty sure it did the same thing.. dumped it into the home air.
Robert Cookson ,
What about the lint?
@@bigred9428 Never been a problem with it. always clean filter in the dryer it is a pretty long run to where it dumps into the house the may help.
@@DuncanCunningham it's no different than using an unvented gas heater
Bryan Hensley Which is equally suspect. Unvented gas appliances belong in museums of Victorian curiosities, not in people's homes.
I'm curious to know what the amount of mold growth will be inside the unit...anywhere water sits, like on that coil, mold always grows. Another question is what is the expected lifespan of the appliance...tradition dryers last a long long time.
I know heat pumps work, but the lint is anther question
Well, my LG is now 6 years old and still works perfectly, and my LG washer is 16 years old and has plenty of years left in it.
I was wondering about the mold issue too.
you shouldnt be putting pets inside the dryer hun.
@@1itoasif Or your head to dry your hair after a shower!
They also eliminate the need for your HVAC system to "make-up" for the air being dumped by old fashioned dryers. With traditional gas or electric dryers every cubic foot of air exhausted from your home is replaced by outside air drawn in through cracks and crevices. In the Summer or Winter your HVAC system works harder as a result of that. But with a heat pump dryer this is no longer the case, and you save money on HVAC costs in addition to the unit itself using less energy. win win.
Perhaps assuming you have a whole house hepa air filter and the outside air isn’t a benefit.
Ventless dryers have pros and cons. The pros are energy savings. about 2.5-3.5kW per load. What few people realize is they are venting the heated or air-conditioned air from their home with a vented dryer. The EnergyStar ratings ignore this. Why bother with an air-tight home when each dryer load is like a 5" fan-driven duct to the outside?
The cons are the best ones are European compact models. Why? Because giant US mfg's don't have a user-friendly way to clean the lint off the condenser. With Bosch and Miele, you pull the condenser out and wash it under the tap. With Whirlpool, effectively the only US company to make ventless dryers, you have to call a service tech to disassemble the machine for condenser cleaning. A normal family of 4 needs this done at least once a year. If your ventless dryer is taking hours to dry a load, bet your bottom dollar the condenser is clogged with lint.
Bosch tried to make a high-end ventless dryer with a self-cleaning condenser but it failed in consumer use.
I have the large Whirlpool ventless and I beg the service tech to clean it every year but he hates the job. Some tech's just refuse because it's an ugly job. Whirlpool engineers are not that bright.
I will now search to see if this can run on 120V, which would make it suitable for an off-grid property with only 120V service.
Yes they can 120v 15 amps.
