I would go for a 700VA unit. About $139. Best thing is they protect the circuit board from surges and power outages. If someone is always home that's good unless your stove has some sort of relay that will stop the auger when power is out and let it shut down when the fuel in the pot burns up. Otherwise the UPS (of that size) will just run out of juice and shut down. Hard to tell how long they last due to the differences in stoves and if your stove is running on high or a low setting.
I have a monster 24V UPS, runs about 8-10 hours. I guess lots of people saw my website from the late 90s and started making their own alterations (YouTube) to used UPS for extended times. I was told doing what I did would not work. Now there are tons of videos on what I did 20 years ago.
