There are cheap ways to run a backup heat source. I installed a generator, which makes sense for my very rural location. But before the whole house automatic genset, I used a $100US switch that would allow me to run my LP furnace on a small portable generator. All the furnace requires is 110/120VAC to operate. Something cheaply and easily supplied by a small gasoline powered portable for less than $500US.
