How Long Will It Run

Which power station will run a gas furnace?

A gas furnace draws about 600 W in the UK, for roughly 50% of the time — an average of 300 W. The gas makes the heat, but the blower that pushes warm air through the ducts is a real motor with a real start-up surge — far more than a British combi boiler. Variable-speed (ECM) blowers usually draw less.

Typical figures for a typical unit, last reviewed 2026-08-29 — not a measurement of your appliance. Modelled on www.shareddocs.com. Carrier’s product data for the 58SB 80% furnace lists maximum unit current of 5.6 to 13.4 A at 115 V (roughly 640 to 1,540 W) with direct-drive blowers of 1/3 to 1 hp. Those are maximum ratings; 600 W is a typical running figure for a mid-sized blower at heating speed plus the inducer and controls, and the 1,500 W surge is an estimate of a blower motor starting. Measure your own.

If this is for a power cut

Heating is what a battery does worst. In a power cut, warming people rather than rooms goes much further, and none of this needs a socket.

Without a power station: a 20,000 mAh power bank runs a USB heated throw for about 7 h 24 min. See the power bank numbers.

Hot water bottle and a vacuum flask. Boil water while you still can, keep it hot in a flask, and refill the bottle through the night.

Look for: A bottle made to BS 1970 in the UK, and a flask of a litre or more.

Hand warmers. Air-activated packs give hours of heat with no power at all, and a pocketful helps children and older relatives.

Look for: Long-duration packs, and the expiry date on bulk boxes.

Battery carbon monoxide alarm. Anything burning fuel indoors, a boiler relit after an outage included, can produce carbon monoxide you cannot see or smell.

Look for: A sealed long-life battery and EN 50291 certification in the UK (UL 2034 in the US).
