Pretty much every electric stove in Germany runs on tri-phase 380V. The only one I’ve ever seen that doesn’t was in a student dorm.

- panpanna 7y agoIn 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.

- kuschku 7y agoA typical german stove uses 11kW for the stove + oven combination. Pretty much every stove/oven combination uses 380V 30A for power nowadays. e.g. look at pretty much any Miele stove/oven combination.
- panpanna 7y agoAre you sure? 11kW is a huge number. 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?
- benjymo 7y agoFor my relatively cheap Ikea stove, each cooking plate of my induction stove uses around 1.5 to 2 kW with "Booster" to 2.5 and 3.5 kW. It's connected to three phases and ground through three separate fuses. The oven is separate and connected with a standard plug though.

- ants_a 7y agoStandard power for 4 "burner" stove is 7.2 kW, and can be hooked up on 2 separate phases or on one with a 32A breaker.
- close04 7y agoGermany is one of the few countries that do this though probably because it's common to have electric heating for the house. In such cases you can't get too far on 240V (which used to be 220V not long ago). If you go to the south or the east the chances of having 380V in anything but new buildings are low.
- seszett 7y agoFrance and Belgium also have electric heating in most houses, and electric heating always runs on 240V. It really works just fine.
- ptaipale 7y agoDirect electric heating typically runs on 240 V, but at least in Northern Europe (Finland, Sweden) electric heating is often a central heating via hot water circulation. Here it used to be common that there's a rather large water tank (1 cubic meter or even more) that is heated up during night time when electricity was cheaper, and then gives out the warmth during day. This is no longer a feasible use case because night time usage of electricity has gone up and night electricity is not cheaper. Heat pumps (operating with drilled wells going 100 m deep) have become more common. The pumps take 400V 3-phase.
- Yaggo 7y agoAir-to-air heat pumps are really common. No new houses are built relying on direct (resistive) heating, at least they have water circulation under floor so you can later upgrade to alternative heat sources.
- ptaipale 7y agoExactly. Circulation under floor is good for heat pumps with drilled wells as heat source; there the water is not that hot (often around 40 degrees C after pump.)
