2. Just electric heating, if electricity is cheap enough. Very simple and cheap.
But yeah, heat pumps make that more efficient. At significant higher investment costs. Gotta do the math of whether it is more efficient overall to invest in an efficient energy producer (nuclear), efficient consumers (heat pumps) or both.
Again, building one nuclear plant is expensive. But building tens or hundreds of thousands of heat pumps is certainly also and likely even more expensive.
