Plug Count

How many watts does an electric fireplace use?

A plug-in electric fireplace uses about 1,500 watts with the heater on, and much less (Dimplex says under 300 W) with only the flame effect. Some large built-in models draw up to about 2,500 W.

Watts by model and setting

Most electric fireplace models draw between 300 and 2,500 W while running; a typical one draws about 1,500 W. Assumes 4 hours with the 1,500 W heater cycling about half the time, as Dimplex assumes; flame-only use is far lower.

  • Heater on or off: the flame effect alone uses a small fraction of heater power
  • Heater setting: most 120 V plug-in units max out at 1,500 W (about 5,100 BTU of heat)
  • Thermostat cycling once the room warms
  • Large hardwired or 240 V built-in units can draw more
  • LED flame effects draw less than older bulb-based effects

Running an electric fireplace on a generator or power station

  • Generator: at least 1,500 running watts. A generator rated 2,000 W or more covers it with room to spare.
  • Power station: continuous output of at least 1,500 W. Pure sine wave output is the safe choice for motors and electronics.

Based on 750 W average draw (running watts × duty cycle) and 85% usable capacity.

  • With the heater on it is a 1,500 W load, the same as a space heater, so it quickly drains portable power stations
  • Flame-only mode is light enough for a power station if you only want the ambiance
  • On a generator there is no surge, but budget the full 1,500 W running watts
  • Electric fireplaces produce no combustion gases, but a generator powering one must stay outdoors because of carbon monoxide

Questions people ask

How much does an electric fireplace cost to run?

Dimplex estimates about 8 cents an hour with the heater cycling half the time, and about 3 cents an hour for the flame alone, at average rates.

Can I run an electric fireplace without the heat?

Yes. Most models let you run the flame effect alone, which uses only a small fraction of the 1,500 W heater.
