How many watts does a gas furnace need?

A: A gas fired, forced air home furnace typically requires a small amount of electricity to ignite and operate in your home. Most gas heat furnaces use less than 600 watts of electricity, or less than half of a typical 15 amp electric circuit.

Gas or oil forced air systems can get by with a very small generator – as little as 2500 watts. The power needed is based on the size of the furnace fan motor. See below for details. Electric furnaces and heat pumps typically need 15,000 watts or more to run and cannot be powered by a portable generator.

Likewise, does a gas furnace need electricity? A gas furnace uses the burning of natural gas to create the heat that then goes through the ventilation system. It’s like an old-fashioned stove this way: no need for electric power, just plain old heat from consuming another power source.

Why does my furnace use so much electricity?

This causes a higher electric bill. Dirty filters over a period of time or a lack of filters at all can result in dirty coils. A dirty coil can also restrict air flow. If the heat pump isn’t working, the electric furnace is running by itself to heat the house.
