Go through the main breaker outside?
You must install a switch to disconnect from main power lines so you don't feed back into the main lines and electrocute a lineman. You other option is to unplug specific appliances and plug them into a generator.
To OP:I looked at the pellet stove, but since it does not work without electric power, I bought the Lopi Freedom compact wood stove, which surprisingly keeps 2000 sq ft comfortable even in this weather. It fits in the fireplace and has a stainless flue that goes all the way up the existing chimney and makes State Farm happy for safety.
