There's an assortment of non-electric backup heats. Each has advantages.
Kerosene heater: Comes in different sizes. Portable. Fairly easy to use.
Kerosene commonly available. Relatively safe (safer than storing gasoline).
Propane: Also different sizes. Some use 16 ounce bottles, some use gas
grille bottles. Safer than gasoline if you don't have a leak. Clean heat --
very little odor. Some risk of carbon monoxide.
Burners on stove: Convenient, and there. If you have a natural gas stove,
it's always there, and essentially always available. Puts out some carbon
monoxide. but when was the last time you heard of a hausfrau dying of
monoxide while cooking?
Generator to run furnace: Needs gasoline storage. More hazardous. Provides a
couple hours of runtime, when you can run the furnace and heat the entire
Woodstove or fireplace: Safe if maintained. Good heat, and vents through
chimney. Needs for you to stock wood during spring and summer, you likely
won't find many sources of wood in the fall or winter.
Vented wall heater: Incredibly good idea. Needs no electric (some have a
blower fan). Safe if installed correctly. As dependable as your gas supply.
Talk to your friends, see what they use.
