Cost to run a electric furnace / strip heat

Heating & cooling · typical wattage 15,000 W (10,000 W-25,000 W)

A electric furnace / strip heat draws about 10,000 W-25,000 W (typically 15,000 W). Run 4 hours a day, it uses about 7,200 kWh/year, which costs roughly $111/month and $1,336/year at the US average residential rate of 18.56¢/kWh (March 2026). At a high-rate state like California (33.35¢) it costs more; at a low-rate state like Washington (14.40¢) it costs less.

Wattage source & how to save

Whole-home electric resistance furnaces draw roughly 10–25 kW. They are the most expensive common way to heat with electricity.

Tip to cut the cost: If you heat with electric strip heat, a heat pump typically cuts heating electricity by half or more.
