Cost to run a electric furnace

Electric resistance furnaces draw 15–25 kW when running — by far the most expensive way to heat a home. Running one through a cold winter often adds $300–$600/month.

Ways to lower the cost

•Switch to a heat pump — 60–70% lower running cost. Federal + state + utility rebates can pay for most of the swap.
•Insulate first if your home is older — adding R-30 to your attic pays back in one heating season.
•Lower the thermostat 8°F at night and when away — programmable thermostat saves ~10% in winter.
