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.

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.
