I'm gonna ask something stupid, maybe: what is keeping you from having a minisplit in each room ? You don't have to run them the whole day. Just where you are going to be for a couple of hours.

My guess is: the cost of the minisplits, pretty certain if you had them and turned them all on, you could still draw that much power from the grid.

And probably you are underestimating the cost of nuclear anyway.
