Yeah, but how many amps? What really matters is what your total available wattage is. In the US, 240v@200A (48KVA) is not uncommon. My 1979 house and every other one on the block has that, and that was assuming fossile fuel heat.

That can easily support all the things you listed and do it for a 2500 sq ft house, based on the overly conservative and outdated US NEC lead calculations.
