How to lower the cost of running an electric blanket

Electric blankets and heated mattress pads warm your body directly instead of the air in the room, which is why they use so little power. Most queen-size blankets draw 50–200W on high and much less on low settings. Because you are only heating a few square feet, an electric blanket combined with a lower thermostat setting overnight is one of the cheapest ways to stay warm in winter.

  • Pre-warm the bed for 20–30 minutes, then switch to low or use the auto-off timer.
  • Turn the house thermostat down a few degrees at night — the blanket keeps you comfortable.
  • Choose a dual-control model so each side only heats as much as needed.
  • Winters in Illinois are long, so heating appliances often run more hours here than the national default — adjust the hours above to match your home.
