In EU most new ovens are 240V, partially thanks to the efficiency improvements of hot air ovens.
Still, they used to be 3-phase not long ago so OP is also correct.

e.g. look at pretty much any Miele stove/oven combination.
Just checked one random German oven (AEG) that specifies typical usage around 1kw and max at 4.8kW. Electrolux which is known for energy efficiency claims max 3kW for a similar oven.
Maybe stove is responsible for the rest?
The oven is separate and connected with a standard plug though.
