In many European houses the main power line into the house has a 35A fuse at 230V, so that's only 8kW maximum load. Heating (and water) comes from natural gas,

  In the US I've seen one house with 30amps at 240V (I also heard about a house from that era getting 30 amps at 120 volts), and it was from the 1930s with no updates. Even in the 1950s houses were getting 60 amps at 240V - which allowed for an electric stove to draw 40 amps 240V, and have enough for the rest of the house. These days small houses get 100amps, while large ones get at least 200. Very large houses sometimes get 400 amps. If you install geothermo you get 300 amps because even though geothermo is highly efficient in the worst case it can draw 80 amps at 240 volts (you only see those worst cases when doing the max power test at install time). Unless it is a tiny house I wouldn't not expect 35amps to be enough to run a heat pump any everything else in a house (at least none of the houses I've seen in Europe, though I've only been there for a few weeks total so there is much I have not seen). Large RVs in the US get 50 amps at 240volts, while small ones get 30 amps at 120 volts - both compare to a tiny house in size.

    There are millions of houses like that over here. An 8 kW heatpump is enough to heat the house, and with the high COP that would electrically only be a 2 to 3 kW load.

  Isn't that 35A fuse at 400V?
  • t0mas88 3y ago
    No, it's 35A single phase at 230V or you get a three phase connection which would have 3x 25A and the possibility to get 380V if using multiple phases. But those are getting rarer in newly built houses.
