How much electricity does a space heater use?
A space heater draws roughly 750-1,500 W; we use 1,500 watts running 4 hours/day. That comes to 6.00 kWh a day — 180.0 kWh a month, or 2190.0 kWh over a year — using kWh = watts × hours ÷ 1000.
Most space heaters draw close to their rated wattage when actively heating, which makes them one of the more expensive household appliances to run. New Hampshire prices that energy at 27.24 ¢/kWh, against a 19.32 ¢/kWh national average.
Space Heater operating cost estimate in New Hampshire
| Time period | Energy use | Cost |

What changes the cost the most?
Two things move this number: your state's rate, which you can't change, and how hard the appliance works, which you often can. For a space heater, that mostly comes down to thermostat cycling, room insulation, outdoor temperature.

Source & Method
Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: April 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility. For what's inside the all-in rate, see hidden electricity fees; for how rates and estimates are defined, see the methodology hub.
