How Much Does It Cost to Run an Electric Fireplace? Energy Costs Explained

Last reviewed: October 1, 2026

A simple way to estimate what your electric fireplace will actually add to your power bill.

Start with the exact power draw and your electricity rate

Operating cost depends on the electricity used in the selected mode, your tariff, and operating time. Use the appliance’s documented power draw or suitable measured consumption; there is no universal heater or flame-only wattage for every electric fireplace.

How to estimate your own cost

Cost = watts ÷ 1,000 × hours × price per kWh. For illustration, a constant 1,500-watt load uses 1.5 kWh in an hour. For a dated benchmark, EIA Table 5.3 reports a preliminary U.S. residential average of 18.31 cents/kWh for July 2026, released September 24, 2026 and checked October 1. This national average is not your tariff; use the applicable rate and charges on your utility bill.

Illustrative constant 1,500-watt operation at $0.1831/kWh

Operating time	Electricity	Calculated cost
1 hour	1.5 kWh	$0.27
4 hours	6 kWh	$1.10
4 hours/day for 30 days	180 kWh	$32.96

Calculated values are rounded to the nearest cent and assume constant draw for the stated hours. Thermostat cycling can reduce heater run time. Separate fixed or other applicable tariff charges are not included; the rate benchmark is not a personalized bill estimate.

What actually affects the cost

Thermostat cycling, selected output, display mode, and operating time change consumption. Compare extra-large fireplaces and built-in fireplaces by their actual electrical specifications, not width. Our how-it-works guide explains the separate display and heating functions where fitted.

How this compares to wood or gas

Compare delivered heat, local fuel prices, appliance efficiency, installation, and maintenance costs for the actual alternatives. An electric appliance needs no combustion vent, but converting an existing fireplace may still involve chimney or gas-system work. See the electric, gas, and wood cost comparison.

Common mistakes

Do not treat a national average rate as your tariff, a nameplate maximum as measured daily use, or fireplace width as electrical consumption. Use the maintenance checklist with the manual, and avoid assuming that flame-only consumption is the same across LED, video, and water-vapor designs.

Frequently asked questions

How many watts does an electric fireplace use?

Check the exact model and operating mode. The 1,500-watt figure in this article is a calculation example, not a verified specification for every fireplace.

Does running the flame without heat cost much?

Calculate it from documented flame-only wattage or appropriate measured consumption and your electricity rate. Without that input, a universal cents-per-hour claim is not justified.

Is an electric fireplace cheaper to run than a gas fireplace?

It depends on local energy prices, the actual appliances, operating time, and useful heat delivered. Compare installation and maintenance separately from running cost.

Does the flame effect use electricity even without heat?

Yes. Displays, lighting, and any pumps or other effects require electricity. The amount depends on the technology, settings, and exact model.

Will running an electric fireplace daily significantly raise my electric bill?

Calculate the expected use against your budget. The example constant 1,500-watt load for four hours daily over 30 days uses 180 kWh; at $0.1831/kWh, that is $32.96 before any separate applicable charges.

Final thought

Use your own model’s consumption, your tariff, and a realistic operating schedule. Recheck after installation using the bill or suitable measured consumption rather than relying on a generic promise of a small increase.
