I can't say much Ebbie, except if you don't need it turn it off. If you can, just confine the heat to one room and hibernate there. Keep the rest of the place as 'cold' as you can without freezing the pipes. Never had to deal with something like this, but we routinely have -30 F temp here for a couple weeks at a time.

We close doors, hang blankets in open doorways, and fire the woodstove to max.

If all else fails, find a motel room? Bill it to the power company?
