Can a Power Station Run a Gas Furnace?

By Hicham M. · Updated October 11, 2026 · How we calculate

A gas furnace is dead without electricity. The igniter, the inducer fan, the controls and the blower all run on 120 V; Goodman’s spec sheet puts it plainly: all its furnaces are built “for use on 115 VAC”. We plan on about 600 W running and 1,400 W to start, a cautious pairing from Honda’s generator chart, and in cold weather about half of each hour, so 300 W on average.

At that rate a 1,000 Wh power station lasts about 2.8 hours and a 2,000 Wh one about 5.7 hours. A newer furnace can do much better, as the next section shows.

Runtime by power station

Nonstop runtime for one gas furnace blower fan at 300 W average, with 85% inverter efficiency. Models that can't supply its running or starting power are listed separately below.

Newer furnaces use far less

For most gas furnaces made since July 2019, DOE’s furnace-fan efficiency rules assume a brushless (ECM-type) motor, which draws much less than the older PSC motors. Trane publishes blower watts by speed for its 80,000 BTU S8X1 furnace:

Trane furnace blower watts by speed
Blower speed (Trane S8X1, 80k BTU)Blower wattsBlower on 1,000 Wh
Speed tap 2 of 9105 W8.1 hours
Speed tap 4 of 9263 W3.2 hours
Speed tap 9 of 9667 W1.3 hours

Measured at 0.5 inches of static pressure, blower only, running nonstop. Add the inducer and controls, and remember it cycles with the thermostat.

If your furnace was made after mid-2019, our 600 W planning figure is probably high. Check the blower amps on the furnace’s rating plate.

It has to be wired in properly

Furnaces are hardwired: Goodman’s installation manual calls for an electrical disconnect at the furnace and a separate fused circuit, with correct polarity and grounding. To run one from a power station you need a furnace power inlet or transfer switch installed by a licensed electrician.

Never “backfeed” the house by plugging a power source into a wall outlet. OSHA warns that backfeeding can energize lines “for great distances”, which can kill a utility worker repairing them.

Practical tips

Questions

Can I plug my furnace into a power station?
Only if it has a plug or an electrician has installed a furnace power inlet or transfer switch. Most furnaces are hardwired.
How many watts does a furnace blower use?
Anywhere from about 50 W to over 600 W depending on the furnace and fan speed. A modern variable-speed blower on low can be near 100 W; older fixed-speed blowers run several hundred watts.
