Two quick questions. When your house was new, how was it lighted and heated?
Not very well....
Oil lamps for light and inefficient wood stove for heat. Before that candles for light and a very inefficient kitchen fireplace for heat. Before that we sat around the campfire outside the cave for light and heat!
Although I have a fire pit and camping gear, I'd rather not go back to that during a long term power outage.
So I have a hand fed mark III sitting in the corner of the basement ready to replace the stoker stove if needed.
Couple coleman camping lanterns for light. The kind that have the mantles and use what we call "white gas".
Small 5k watt gas generator for essential's that I run intermittently.
After the generator rush is over next spring I will replace my gas generator with a propane powered unit sized to run the sump pumps, refrigerator & freezer, well pump, septic pump & stoker. We already have a 1k gal propane tank that is a better fuel source for us than trying to source gas and keep the stored gas fresh and carb clean from infrequent use.
