That massive spike of 50c/kWh at the left looks tiny compared to today even though that’s already insanely expensive

    This is such an outdated information. Modern heatpumps work just fine even in temperatures of -20C and below. Ofcourse the efficiency gets worse the colder it is but even at worst it’s still 100% efficient. On a typical year there’s only a handful of really cold days. It doesn’t make sense not to get a heatpump just because it’s inefficient for few days. It’s not like it stops heating or something. It just effectively turns into electric radiator which is what my house was heated with before I got the heatpump anyways.

      Not quite, in my experience on really cold days my heat pump struggles to keep up. This is expecially true when the outside unit is frosting up. The unit has to reverse and pump heat out of the house.

      That’s one of the reasons i run my wood pellet stove on those days. The secondary source of heat takes the load off the heat pump.

        In an area that gets very cold, a geothermal heat pump (which uses the ground rather than the air for heat exchange) would work better than an air-source heat pump. More expensive to install though, and you need a good amount of land

          It’s basically what modern homes should have built below them. Then it doesn’t need extra space. Wonder if it’s already enough to put some pipes a meter below the basement?
