> So how would you run an instant water heater or electric induction stove then? Every apartment and house I've ever lived in had 380V three-phase right to the kitchen,

I run an induction stove on 220V single phase every day here in the US.

Isn't it two phase? AFAIK in the US you have 240V two phase with 180° between them.

The US uses a single, split phase
