Raife, since you don’t have a gas furnace, you might want to consider installing a freestanding stove that uses either NG or wood pellets for fuel. Until recently, I had a wood burning stove, and one of the circuits I made sure the standby generator energized was the one that the stove uses for the blower fan.
After over 30 years of dealing with firewood, though (actually it’s the firewood dealers I was sick of dealing with) I replaced the woodstove with a Harmon XXV-TC pellet stove. I can’t say enough good things about that stove. It is totally automated in its operation, and the maintenance of it is so much easier than than a wood burner. Building a fire in the pellet stove involves touching the “On” icon on the touchscreen panel on top. It lights itself and controls the burn rate to maintain the room temperature with a wireless temperature sensor. The fuel is so much easier and cleaner to store, too.
We never lost power during that winter storm we just had, but the igniter in my main gas furnace decided to fail the day it started snowing so I couldn’t use it. The pellet stove was providing most of the heat in my house for several days. The burn rate got as high as 70 lbs/24 hrs, or almost two bags a day. I would have been hurting without it.
I know there are also freestanding NG fueled stoves that look similar to a pellet stove, and their power requirements would be about the same. Probably less maintenance than a pellet stove though.
