Electric resistance furnaces are among the most expensive ways to heat a home. With 10–20 kW elements, even a few hours of runtime a day dominates a winter bill, which is why heat pumps typically cut that cost by half to two-thirds.

How to lower the cost

  • Seal ducts and add attic insulation first — every leaked kWh from a resistance furnace is full price.
  • If you're on resistance heat, a heat pump upgrade usually has the fastest payback of any home energy project.
  • Lower the thermostat a few degrees at night; with resistance heat the savings are close to proportional.

Frequently asked questions

How much electricity does a electric furnace use?

A typical electric furnace draws about 12,000 watts in use. At 5 hours/day, that works out to roughly 60 kWh per day, or 1,824 kWh per month.

How much does it cost to run a electric furnace for 1 hour?

At the current U.S. average residential rate of 18.3¢/kWh, one hour costs about $2.20. In Louisiana (12.7¢/kWh) it's $1.52, while in Hawaii (48¢/kWh) it's $5.76.

How much does a electric furnace cost to run per month?

With typical usage (5 hours/day), expect about $334 per month at the U.S. average rate — from $232 in Louisiana up to $876 in Hawaii. Rates are as of July 2026.

Does a electric furnace use a lot of electricity?

Yes — at typical usage it accounts for roughly 206% of an average U.S. home's monthly consumption (885 kWh), which makes it one of the larger loads in the house.
