    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      Sitting up here in the Alps, winter approaching, laughing at your two-decades-out-of-date ignorance 😂

        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
