  1. I think all new houses should be built to be fully electric. And 100 A seems plenty unless you can get really cheap service with higher max current.

  2. To be honest, the price of electricity has been very volatile here in Europe since the Russia attacked Ukraine. Price has been anything between 9 EUR/MWh and 550 EUR/MWh practically randomly (mostly based on wind patterns).

  3. I write software for living and I definitely belong in the group that thinks that critical systems (e.g. home heating) should not be connected to Internet. I have about 1% confidence that the manufacturers of heating appliances get software security correct to prevent hackers from taking control over the internet.

  4. Hello from Finland! Here single family homes typically have 3-phase 25 A connection. That gives theoretical max limit of 3*25A*400V = 30 kW. That's plenty to run modern houses all electric even when it's really cold outside. Our house heats the water and the house with electricity, the induction stove is fully electric and AC is fully electric (Mitsubishi LN25 so it will pump heat from outdoors to indoors even when it's –30 °C or -22 °F outside). And we have a sauna, too, which takes extra 7–9 kW, too. That said, if you want fast charger for your EV, you would need to get much beefier connection and that gets really expensive really fast here in Finland. Let's say you wanted 100 kW fast charger for your EV. It would require 3-phase 100 A connection and the montly payment for having that kind of connection would cost 167 EUR before even using any electricity. We obviously have thing called insulation in our houses. Our house has about 120 m² or 1300 sq ft and it can stay heated (we have 22 °C indoors) and heat incoming air (about 60 liters/s) with about 6 kW even when it's -30 °C outdoors (and that's assuming the both our heat pumps were broken). With properly insulated house, you could heat a literal mansion with 80 kW system.
