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.
Questions
Frequently asked questions
How much does it cost to run a space heater for 24 hours in Utah?
Running a 1,500W space heater for 24 hours uses about 36.0 kWh, which costs about $4.72 at Utah’s average rate of 13.1¢/kWh.
How many kWh does a space heater use per month?
At 8 hours a day, a typical space heater uses about 365 kWh a month. In Utah that costs $47.89.
Is it expensive to run a space heater in Utah?
Utah has the 3rd-cheapest residential electricity of the 50 states and DC at 13.1¢/kWh — one of the cheapest. Running a space heater here costs about $575 a year at typical use, compared with $802 at the national average rate.
What is the electricity rate in Utah right now?
The average residential electricity rate in Utah was 13.1¢ per kWh in July 2026, according to the latest EIA data — down 2.5% 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.
