Saw a blurb about this but don’t know much about it, anyone’s thoughts on “heat pumps”?
Apparently they use electricity to bring heat from outside in to the house in winter, and draw heat out in summer?

so it might be useful for like a hybrid system that could run in in a more normal temperature range and then switch off when it gets hotter or cooler?
