Er yeah, pretty obvious it doesn't work. You'd have to be nuts to get one of these ridiculous contraptions installed, I don't care what the shysters who promote them claim.

@nikodga5577 if its 1 degree C outside and 10 degrees C indoors, you can't warm up your house with the outside air no matter what mumbo jumbo you say.

@nate0031 didnt say they didnt technically 'work', just saying that if its colder outside than in, you will be using lots of electrcity and might as well just use heaters inside the house.
2
@nate0031 if it doesnt work in really cold weather, it's useless to me.

Seems we've invented a perpetual motion machine.
1
@CSNCSNCSN Yes exactly, these things will end up using a lot of electricity.
1
@aaronsmith9688 they don't work to heat your home when it's cold outside. can't provide heat from an environment thats colder than what you're trying to heat.
1
@aaronsmith9688 you can't heat something up using energy from something that is colder than the thing you're trying to heat. it would be more efficient just to use electric heaters inside your home than suck in cold air to a heat pump and heat it up.
1
@FlyNAA the air outside the house is colder than the air indoors so it is using something colder to warm up something warmer. physics says that can't be done.
1
@FlyNAA Right. that does happen, but it's not an effective way to heat the room.
1
@FlyNAA what i mean is that it can't possibly be more efficient to try and warm up a home using this device when its cold outside compared to just using electric heaters indoors.
1
@FlyNAA as I said, impossible that it could be more energy efficient using one of these in cold weather than just using, say, electric radiators. I have read many stories from former heat pump owners who said the heat pump was useless in cold conditions. your explanations don't really make sense.
1
@FlyNAA the report tells me nothing, I need to know how much energy the pump used and what temperature did it heat the indoor space to with that energy. seems basic information like that Is disguised with mumbo jumbo.
1
@TrendyWhistle where are the figures? say its 2 degrees C outside and 10 degrees C inside. How much energy does the heat pump use to get the indoor temperature to 20 degrees C?
1
@TrendyWhistle so its not more efficient than heaters when you actually need it most when its very cold. that's what i'm saying. why would you spend money on something that doesnt work in cold weather.
1
@TrendyWhistle Yes I can believe that it does work quite well if it's not too cold. But it needs to work when it's very cold or it's not much use.
1
@FlyNAA Thing is here in my apartment I don't need any heating on anyway when it's not particularly cold outside.
1
@FlyNAA it does need heat, it just doesn't need it when it's not particularly cold outside which is the only time heat pumps work lol. heat pumps are useless, QED.
1
@hkelly1623 nonsense. you would be much better off just using heaters inside your home if its really cold.
1
@martinmillar8447 They are useless in temperatures below 5 degrees C or in poorly insulated homes, which is most UK homes. Not suitable for my home, that's for sure.
1
@martinmillar8447 useless for most UK homes as the insulation isn't good enough. they can be used successfully in Passive House type buildings but there aren't many of those.
1
@arnabbiswasalsodeep i have a gas boiler that heats hot water for my radiators. It works just fine.
1
@DuckInGameStop yes i did. heat pumps are no good in cold weather.
1
What a load of mumbo jumbo. It's against reason to think you could efficiently warm up your home with air that's a lot colder than the air indoors. Can't possibly work without using loads of electricity. It is most certainly not going to be more energy efficient than just burning gas onsite to fuel central heating.
1
You don't understand heat pumps warming up a home with cold air because it's a scam and it doesn't work , that's why. If something is cold, you can't use it to warm something up that is already warmer.
1
@Aquatarkus96 yes but in winter it's colder outside, so how on Earth can you heat the inside of your home with this?
1
@Aquatarkus96 I did, the laws of physics remain the same as they were before I watched it. You can't warm up your house using air that is colder than the air in the house.
1
@Aquatarkus96 air conditioners work but use a lot of electricity. this device will also use a lot of electricity. you might as well just use electric heaters. there is no such thing as a free lunch.
1
@Aquatarkus96 nonsense. again., there are no free lunches. if it's colder outside than inside, you can't use that colder air to heat your house.
1
@Aquatarkus96 yes at what energy cost? you might as well just use electric heaters inside your house as attempt to 'collect heat' from 1 degree celsius outdoors air.
1
@andruloni i don't own a heat pump.
1
@andruloni You can't sue people for a defective product unless you own said product. I'm not dumb enough to buy one. Even if I did own one and sued them, you don't profit from such a legal action you just get made financially whole.
1
@dreugh424 it physically can't 'work' according to the law of entropy. You can't get more than 100 watts worth of heat from 100 watts of electricity. I'm not aware of any actual scientist who would claim otherwise.
1
@dreugh424 I'm not lost. I understand entropy that's all.
1
@dreugh424 it 'works' sure, but only at the cost of a lot of electricity. it would be more efficient just to use an electric heater indoors.
1
@vincemorgan9640 I understand it very well and so will anyone who tries to heat their home with a heat pump when its below freezing outside.
1
@vincemorgan9640 it is when it is very cold outside that you need heating, that is obvious. heat pumps are therefore a waste of money.
1
@vincemorgan9640 you can't 'move heat' without expending more energy overall than just producing heat where you need it. you can't defy entropy. end of story.
1
@vincemorgan9640 petroleum is nothing like what a heat pump does. petroleum represents millions of years of stored solar energy. however we are approaching the point where it will no longer be worth drilling for oil due to diminishing energy returns on drilling, all the good oilfields having been long ago used up.

@Redtooth75 you can't beat entopy.
