Almost Self-Reliant
with the pellet stove, you may be better off to buy a couple of deep cycle batteries, and a cheap inverter. Much quieter than a generator, and should run the stove for a while. It would cost much less to run than a generator as well. You could recharge the batteries off of the generator while you were running the pump.
Now there's some good advice!
Back in Oct. '10 we had a preseason snowstorm when most of the trees still had their leaves. It was not pretty. For heat we were running a Hotblast 1400 wood furnace. It has a blower that pushes the air through the ductwork. It seemed like such a waste to run the genny for just the blower. I already had 2 deep cycle batteries and a small 400w inverter. I hooked up one of the batteries and plugged the blower into the inverter, which said it was drawing +/- 20w. One fully charged battery ran for about 16 hours. When it got too low the inverter shut off. I put the other one on then charged the first while I was running the genny for the fridge and freezer. Did this for 3 days until the power came back on.
I don't know anything about pellet stoves but if they draw less than 100w, batteries may be a viable option.
