I have a house from 1909, with relatively poor insulation, by modern standards. We heat the house with a heat pump and a 100 m deep borehole. The heating of the house (180 m2 and a cellar) is the main energy consumption. The total was 22 000 kWh last year (including about 3 500 kWh for an electric car). An old house with electric heating and cooling could well be what he has. When we moved in the electric consumption per year was way higher, 35 000 kWh. We have gone through and made the house more effective, better white goods, windows, better ventilation etc. We also sold about 2 000 kWh of excess production from our solar panels.

"An old house with electric heating and cooling could well be what he has." Definitely could be the case. Your situation is interesting in that it is opposite to the order of transitioning towards a heat pump over here. Perhaps a heat pump was your starting point as there was no gas connection? Over here we start with gas heating (almost every house) after which we try to transition towards a heat pump. They say you should first insulate your house to the maximum possible before even considering a heat pump. Fail to do this and the heat pump won't even be able to produce enough. This calculation is of course locally specific, unlikely to apply to you. In fact, many houses will never be able to transition and will end up with a hybrid pump as the maximum achievable.

  Before I owned it, our house had an old oil/wood burner. And our heat pump doesn’t need help from an electric heater until it goes below -15C or so. But then it is a 20 year old heat pump.

An old house in California wouldn’t have electric heating. Even new houses scarcely have electric heating.

  Tell that to my old CA house.. we rely on electric space heaters a lot.

    I mean built into the house, like a fireplace, stove, furnace.
