How to lower the cost of running a space heater

A space heater is a resistance heater: virtually every watt it draws becomes heat, so a 1,500W model uses 1.5 kWh for every hour it runs on high. The low setting on most models is around 750W. Ceramic, oil-free fan heaters and infrared models all have the same electricity cost for the same wattage — the difference is how the heat is delivered, not efficiency. A built-in thermostat lowers the real-world cost because the heater cycles off once the room reaches temperature; our estimate assumes it runs at full power for the hours you enter, which gives you a safe upper bound.

  • Heat the room you are in, not the whole house — lower your central thermostat a few degrees while the space heater runs.
  • Use a model with a thermostat and an eco mode so it cycles off when the room is warm.
  • Close doors and block drafts so the heat stays where you need it.
  • Winters in New Hampshire are long, so heating appliances often run more hours here than the national default — adjust the hours above to match your home.

At 8 hours a day, a typical space heater uses about 365 kWh a month. In New Hampshire that costs $97.10.

Is it expensive to run a space heater in New Hampshire?

New Hampshire has the 8th-most-expensive residential electricity of the 50 states and DC at 26.6¢/kWh — one of the most expensive. Running a space heater here costs about $1,165 a year at typical use, compared with $802 at the national average rate.

What is the electricity rate in New Hampshire right now?

The average residential electricity rate in New Hampshire was 26.6¢ per kWh in July 2026, according to the latest EIA data — up 16.7% from a year earlier.

Is it cheaper to run a space heater or central heat?

Heating one small room with a 1,500W space heater is usually cheaper than heating the whole house with an electric furnace. A modern heat pump, however, delivers 2–4 units of heat per unit of electricity, so it can heat a room far more cheaply than any space heater.

Do ceramic or infrared space heaters use less electricity?

No. All electric resistance heaters turn about 100% of their electricity into heat. A 1,500W ceramic heater and a 1,500W infrared heater cost the same per hour.
