By installing a heat pump in his house in the hills of Oslo, Oyvind Solstad killed three birds with one stone, improving his comfort, finances and climate footprint.
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
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.
