Operational costs range between 0 003 to 3 cents per hour when you use them strictly for decorative purposes that is the flames are activated but no heat is produced.
Electric fireplace energy usage.
If they are set so the heater powers on and off the 50 percent usage setting they use about 9 cents an hour in electricity.
