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?

Depends where you are.
If it doesn’t get that cold outside, you can get back considerably more heat than you put in energy. If it does get quite cold outside, there’s a point it becomes first as efficient as electric and eventually it stops working altogether. I live somewhere that routinely sees -40C, by that time you basically are fully on a normal furnace.
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?
