I'm interested in using European kitchen appliances to heat things faster.  My house is a 2014 construction in America, split-phase power.

My understanding is that their 230V toasters, kettles, and toaster ovens cook faster because they have more watts available due to the higher voltage on a given size of wire.

Understanding that I'd have to avoid appliances with electronics and motors, What are the pros and cons to adding a circuit to my kitchen with European outlets?

I imagine that I might have to use a breaker smaller than optimal for the European outlets since American and European breakers don't come in the same capacities.  What else could I be missing, and is there a better way to accomplish this?

It would be nice to have a microwave that was twice as fast too, but that definitely gets into electronic and motor land.  Not to mention the magnetron might derive its frequency from mains.
