Cost per 30-day month. EIA's state figure is the average price residential customers paid (revenue ÷ kWh sold), so it includes delivery charges. Your own utility's rate may differ.
Because prices were up 11.2% from a year earlier, the same 8-hour month on high went from $56.81 to $63.18. At the U.S. average it is $65.92.
What a whole winter costs
Most heaters only run part of the year. Four hours a day on high from November through March (150 days) uses 900 kWh, about $158 in Virginia at today's average price. The same season on low is about $94.77.
Ways to pay less
- Drop to low once the room is warm. 900 W instead of 1,500 W saves about $25.27 a month at 8 hours a day in Virginia.
- Turn the central thermostat down while you use it. A space heater only saves money if it lets you heat one room instead of the whole home. DOE estimates up to 10% a year in heating savings from setting the thermostat back 7–10°F for 8 hours a day.
- Use the timer. Left on around the clock, a heater on high would cost about $190 a month in Virginia. Many models have an auto-off timer.
- If electric heat is your main heat, price a heat pump. DOE says heat pumps can cut the electricity used for heating by about 50% compared with resistance heaters like space heaters and baseboards.
Safety. Plug space heaters straight into a wall outlet, never an extension cord or power strip, and keep them at least 3 feet from beds, curtains and furniture (CPSC).
