Well France did move to electric everything (cooking, hot water, heating) in the past thanks to ample nuclear electricity production (and possibly not too harsh winters). Unfortunately they let their nuclear programme decay and are struggling now (EU grid integration does not help)...
I think a big part of the push to install heat pumps now is that it is understood that electricity production is in dire straights, taking into account that the transition to EV requires a lot of electricity.
