> I just happen to live in a city where this is quite common - whole streets where every house with multiple apartments has electric heating (overall not a majority by any means but still common). I was contrasting with other countries where this is not only uncommon, it's basically completely non-existing.

You extrapolated from "common in my city" to "common in my country", and a fairly large one at that. That isn't contrasting anything; its just plain wrong.
