    it cannot be the only source of heat in a lot of cold climates.

    I live in Finland. Heat pump is the only source of heat in my house.

        The same thing that happens when you have electric or gas heating. It stops working, because none of those work without electricity nowadays. Hell if you have a coal/wood burner for central heating chances are it doesn’t work without electricity either.

          How often does it got out in Germany At least Finland built a Nuclear reactor to power most of the country unlike Germany which shut all their’s down

            afaik power never really goes out in western europe unless something happens to the infrastructure (e.g. lightning strike or tree falling on a power line), what instead happens when we run out of generation capacity is that prices skyrocket.

            In my house? Pretty much never. We have solar as well as a grid connection and can connect a generator as well.

            In fact, I even have a second stand alone portable solar system that we take camping. It’s not powerful enough to heat a house… but it is powerful enough for pretty much everything else. And I can heat my house with a fire if it came to that.

            Redundancy is the name of the game if you’re worried about reliability.

        Some of the stations in Antarctica use heat pumps. They have been proven to work effectively at -53°C (-64°F) and do so reliably.

        Are they more efficient at more reasonable temperatures? Yes. But they still work even when it’s very cold outside.

        How well a heat pump works in cold temperatures obviously depends what temperatures it was designed to operate at. Don’t waste your money on a model that is designed to operate in a different climate. In fact a lot of heat pumps aren’t even capable of heating at all - they can only output cold air (which they can do even if it’s stinking hot outside by the way).

          Are you intimately familiar with the inner workings of your heatpump? Nearly all heatpumps in a cold climate have backup heat built in and it would automatically switch to backup when it gets too cold outside. -30C is well into the too cold category for it to function as a heatpump alone

            Which makes the argument that heat pumps don’t work in the cold completely wrong from a user perspective.
