What an electric fireplace costs to run

A 1,500 W electric fireplace costs about 27.5 cents an hour to run on full heat at the June 2026 US residential average of 18.34 cents per kWh. That is about $99 across a 90-day winter at four hours a night. With the heater off and only the flame running, the same evening costs about 7 cents.

cost per hour = (rated watts ÷ 1,000) × your rate in dollars per kWh

For a 1,500 W unit at 18.34 cents: 1,500 ÷ 1,000 = 1.5 kWh per hour; 1.5 × $0.1834 = $0.2751. That is the whole calculation. Every cost figure on this site comes from that one line of arithmetic, implemented once in the code so no page can disagree with another.

18.34 cents per kWh is the US residential average from the EIA's Electric Power Monthly, Table 5.3, for June 2026, released 2026-08-26. It is a national average and your own rate is on your own bill — state rates vary widely around it, and that variation matters more to your answer than anything about the fireplace.

Residential electricity rates across US states span a range wide enough that the same fireplace can differ by a factor of two or more between one household and another. That is a bigger swing than any difference between products, which is why we built the calculator rather than publishing a single number and leaving it there.

Flame and heater are independent controls on essentially every electric fireplace made. Switch the heater off and the draw collapses to the LED assembly and its controller. We use a deliberately conservative 100 W for that figure across the whole site — many units draw considerably less — which at 18.34 cents per kWh works out to under two cents an hour.

For a lot of buyers that single figure reframes the purchase entirely. If what you want is a fire to look at on a winter evening, running one every night from October to March costs a few dollars. The expensive part of owning an electric fireplace is the heating, and the heating is optional.

Only if you turn the central thermostat down. That is the entire condition, and it is the part most often left out.

• Added to your existing heating, an electric fireplace is a pure addition to the bill — about 27.5 cents for every hour it runs on high.
• Substituted for whole-house heating, it can cost less, if the room you are heating is small and the rest of the house genuinely gets cooler.
• Against a gas furnace, electricity at 18.34 cents per kWh is generally an expensive way to make heat, so the zone case is weaker.
• Against electric resistance heating, it is the same energy in a nicer-looking box — no saving, no loss.
• Against a heat pump, an electric fireplace is usually the more expensive source per unit of heat, because a heat pump moves heat rather than making it.

Negligible, and we are not going to invent a number for it. Units with remotes and displays draw a small standby load, but it is a rounding error next to a 1,500 W heater and it is not worth planning around. If you want it at zero, unplug it in the summer.
