Heat pumps can't take the cold? Nordics debunk the myth
Heat pumps can't take the cold? Nordics debunk the myth
There is a discussion on Hacker News, but feel free to comment here as well.
Think most people know this is the case. We use heat on pumps. It's not particularly cold but -1.
I have a heat pump and a gas furnace. The furnace is only used if the heat pump isn't able to heat and that's typically around -25c. This keeps me off gas most of the winter.
Science proves otherwise...in cold enough temps the heat pump is literally useless and you will need a backup source like electric dor gas/bio fuel.
Sitting up here in the Alps, winter approaching, laughing at your two-decades-out-of-date ignorance 😂
I live in NC where a very cold day is +20F and I have to say I do not feel my heat pump keeps my house very warm. Maybe l just have a very high expectation of what a warm house feels like, but based purely on comfort I would not pick a heat pump. My house is only about 7 years old, so maybe the technology has improved since then?
it’s just physics, and at sub-zero temperatures the air heat pump simply switches to electricity it’s another matter if your pump uses the ground or a well, then of course it will work at any outside temperature
Physics isn't wrong. Ground source is better, but air source won't keep up with multiple days of sub temps
