We have a wood burning fireplace insert (vs free standing stove) and a few days each winter we lose power. The blower on the fireplace uses about 100 watts and can help keep the house comfortable in sub-zero weather. That’s why we have a small battery/inverter. We have a “generator switch” near our electrical panel that powers just the circuit that the fireplace blower is on. In normal mode the circuit is powered by mains.
