Meanwhile, here in Germany, we have 230V, but every standard wall outlet is rated for 16A continuous load over 1 hour so you can get 3.6 kW on each circuit.

Your standard home has a supply of 3 phase power @ 35A (southern Germany) or 63A (northern and western Germany), I think only the former GDR is at standard 3x25A, because like in many former Communist countries they had to save on expensive copper and aluminium, and since a lot of the GDR was heated by steam-based central district heating systems, you didn't need that much power anyway.

Lot's old homes and flats here limited to 5A or 3A 220v. If you don't use electric heating your power demands go down substantially, though 3A is a bit small these days.
