When I was a kid in the 1970s, we did have a gas oven, but soon replaced it with an electrical oven that still had a gas stove on top. The simple fact is that electrical ovens are safer and more practical than gas ovens, while gas stoves were more practical than electrical stoves before induction stoves became available.

So having access to both 3-phase current and gas, we make our choices based on what's convenient rather than on what we're forced to use.

As I wrote in https://news.ycombinator.com/item?id=20799176, in Germany, electrical house heating is very uncommon.

My point is that it's still more common than other countries, especially south and east of Germany, as I made very clear above (that even was there to help make the point). And in this comment I didn't forget to mention electric stoves and ovens which are very much a common thing. According to the spec my stove (radiant) and oven together top up at 9.6KW usable, not just adding numbers for each burner. That's double or triple what you'd get out of any regular 240V wiring (usually ~2.5KW/10A, sometimes ~3.6KW/15A, haven't seen 4KW 240V sockets so far). With an induction stove you could go lower overall but almost all electric ovens out there are in the 3-3.5KW range. I imagine it's the reason every single house I lived in had 380V.
