If you already have a system where everybody uses electricity in house warming its far, far, far (and lots more fars) easier to switch to heat pumps while in Germany lots of houses have gas/oil heating. Going from that to heat pumps is 100x more difficult and costly.
France is in a much better situation. Better isolation, heat pumps are technology independent, you just need reliable electricity.
- _ph_ 4y agoActually it is the other way around. The houses designed for electric heating usually don't have any heating pipes but just resistive heaters as part of the floor. You cannot convert that to heat pumps, you have to build a new heating system into the house including laying pipes, new floors. On the other side, if you have a central heating system, you can replace the burner with a heat pump and leave the rest mostly unchanged. I say mostly, as you want to optimize the whole system towards lower water temperatures to get higher efficiencies of the heat pumps. But this can be done, and if you have in-the-floor heating already, this can be skipped as that works with low water temperatures anyway.
- rightbyte 4y agoYou can have airair pumps, but ye airwater or waterwater (ground heat) is better. Especially if the house is not small.
- ahartmetz 4y agoSwitching from electric heaters to heat pumps is very easy for the grid, but not at all easy in existing homes. Central heating needs water pipes, which traditional electric heating doesn't have. Adding the pipes is going to be a major hassle. I'm not sure if there is a major difference in insulation. Old houses are in Germany are not great, new houses usually are, and it's probably the same in France.
