At this rate he’s gonna somehow find a car powered off a heat pump
Or a heat pump dishwasher? If he finds a way to turn a heat pump into lighting he’s got it made.
There are heat pump dryers. They plug into 120v and can often work without a drain if your willing to empty them manually afterwards.
Honestly, a heat pump dishwasher is probally fully possible but not necessary, as they only use like 5 gallons of hot water.
If you want to dry clothes with a heat pump would a dehumidifier be even more efficient?
A dehumidier is a heatpump, just one designed with “remove water” as the core function.
I think the dryers probally are mainly really aggressive dehumidifiers, which also heats the clothes.
Stirling engines have powered generators. No reason you couldn’t run a light on one. However it would be impractical for any real world house use for a long list of reasons in not about to type up.
TIL water heaters and space heaters are commonly separate units in the US.
In Europe we space heat with hot water too, so this is a single unit.
That used to be more common in the us. However forced air is more efficient (at least traditionally, not sure what the latest is) and most importantly allows for cooling which is needed when the summer gets as warm as the us normally does.
Space heater in the US refers to something different.
Home heating may be done using steam in radiators. As far as I’m aware this is most common in older buildings or in the north. New York has district heating that seems to resemble district heating found in parts of Europe.
A space heater in the US is a resistive electrical heater, that isn’t usually connected to the main heating system for the home. Typically these are small portable units, and they’re used to heat just the room they’re put in. Your thermostat might control several rooms, but you might not intend to be in those, and night not want to pay to heat all of them. Or it’s unusually cold, so you use a space heater and just stay in that room.
I’ve heard of these! They are a really nifty innovation that’s ideal for warm climates
In some special circumstances, yes. But I also have one of these air to water heat pumps and it is entirely off during half of the year or more as the much cheaper solar-termal tubes on my roof cover all the hot water needs (and use the same water tank). I was expecting to be able to use the cold air and installed special openings in the cold air duct, but in the five years or so since I installed the heat pump I never even once had the opportunity to do so.
I’m not convinced that having solar thermal tubes on your roof is ordinary circumstances and not having them is special circumstances
Unless you own an apartment in a larger arpartment complex, you are not allowed to install such a heat pump (as a renter), and in every other scenario of home ownership you are very likely better off installing solar-thermal tubes on your roof. And in hot climates these tubes are extremely common.
They’re cheap and operate for free. It is quite common in warm climates.
I’ve got one of these, tho its a 240v. State brand but same company basically.
Heat pump failed last year, replaced under warranty, no issues since. Keeps the room with the networking gear and NAS nice and cool!
Mine is cooler, it is a single unit that sits outside and heats my water and my house.
Bonus: when someone has a shower in summer and I am sat outside in the garden, I can position myself in front of the fan of the heat pump for a nice cool breeze.
I have a heat pump water heater that’s vented to the outside and I call it my outdoor air conditioner, it’s so nice to stand under the vent on a hot day and get cold AC on my neck.
Kinda curious how much of a difference to efficiency you get with it being vented. Mine has a massive fan and heat sink on it and that sits outside. Surely limits the potential airflow unless you have a 1m wide hole in the side of your house.
I have two 8 inch penetrations that are ducted directly to the water heater, an inlet and exhaust. During summer I imagine I’m getting fantastic efficiency with source air being from outside at 80+ degrees (F). In winter we do have occasional freezing temps but usually above 40ish. I don’t have hard efficiency numbers but I’ve had it for over a year now and have definitely noticed savings on my monthly electric bill.
I should mention the water heater is in a closet, hence why it’s ducted.
Suppose it does depend on what you compare it to, still far more efficient than an overpowered electric kettle.
