Cost to run a space heater (electric)

Most plug-in electric space heaters draw 1,500 watts at full power. Convenient for one room but expensive — running two heaters all day in winter can add $100+/month to your bill.

US average: $0.16/kWh. CA & HI: $0.30+. Look at any electric bill for your exact rate.

Ways to lower the cost

  • Only use in occupied rooms — turn the central thermostat down a few degrees while running.
  • Avoid using for whole-home heating; a heat pump uses 1/3 the electricity.
  • Never leave running unattended; never plug into a power strip.
