If you must pick one, go with propane, as it is not dependent on a third party provider like natural, that’s of course if you install a BIG tank.

Mine is both natural and propane, although I am only hooked up to my propane tank at the moment.

If your whole house is electric, install another auxiliary propane powered heat source as well.

Maybe even get rid of the electric range and go propane.

Then bury a monster tank underground and keep it full. 1000 gal minimum

Give a man a fish and he eats for a day. Give a man a welfare check, a forty ounce malt liquor, a crack pipe, an Obama phone, free health insurance. and some Air Jordan's and he votes Democrat for a lifetime.
