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.

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      Sitting up here in the Alps, winter approaching, laughing at your two-decades-out-of-date ignorance 😂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

          I will say, it is unseasonably cold the last few days (40’s) and my house is comfortably warm. But I cannot imagine going days sub freezing and the heat pump keeping up. But I am a spoiled American.

          Are you saying it struggles to meet the temp set on the thermostat, or that you/your spouse sets the thermostat too low?

            I am saying the heat pump struggles to keep up with the temp on the thermostat. It runs constantly and cannot maintain the ~70 we have the thermostat set too.

          Nothing to do with the heat pump, everything to do with building standards over to last couple of decades

          Saving power for even a few extra months still saves money. You can have both a heat pump and a normal gas furnace. They aren’t even that expensive. If you have a high heating bill, it could pay itself off in a few years.

        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
