This would work for a passive gas furnace like an old gravity furnace. Modern high efficiency gas furnaces require electricity for the blower.

- endisneigh 5y agoYeah, unfortunately. Though I suppose if this were really an issue you could keep a battery around as they don't really use that much electricity.
- nostrademons 5y agoYeah PowerWall or generator is really the solution for this. They're surprisingly big electric hogs though - our furnace is 500W and is our biggest power draw during the winter. A PowerWall will only power this for about a day of continuous usage (realistically heater use won't be continuous because of thermostats and insulation, but it can be appreciable in cold climates).
