My central heat is gas and requires lectric, BUT I have 1 Gas fireplace with ventless logs and 1 gas heater in my other fireplace. Neither of them need lectric so I feel fortunate.
Wolfie, You might want to look into one of those corner or wall ventless fireplaces and pipe some propane to it. No lectric needed. You can run it as needed or not if you got plenty of other heat. They also have a thermostat built in which will cut them on and off. I really like mine.
