Well, Germans like to use three-phase power for their electric ovens.

(Still nominally at 230 Volt, but it's not quite the same as two-phase power.)

So in Europe the phenomenon of a stove heating faster than a kettle would not be observed. Isn't that what I said?

230V/3kW induction stove boils a cup of water faster than you can get the cup from the cupboard.
