Electric Fireplace Running Cost Calculator: How Much Electricity Does It Use?

Every cost guide for electric fireplaces publishes the same figure: $0.15 to $0.25 per hour. That range was built on an electricity rate that does not match what most people actually pay. The national residential average reached $0.1844 per kWh in May 2026 per the U.S. Energy Information Administration, and state rates vary from $0.12 in Idaho to $0.52 in Hawaii. Your actual running cost depends entirely on three numbers: your wattage setting, your local electricity rate, and how many hours per day you use it.

Enter your numbers below. The calculator returns per-hour, daily, monthly, and annual costs, plus a comparison to what running your whole home on central heating costs per hour.

The Two Wattage Settings and Why They Change Everything

Every electric fireplace sold in North America operates at one of two power draw levels: 750 watts and 1,500 watts. The 750-watt setting powers the flame effect, the LED lighting, and the motor that creates the illusion of moving flame, but produces no meaningful heat. The 1,500-watt setting adds the resistance heating element and raises power draw to the equivalent of a full-size space heater.

That distinction matters enormously for running cost because most users run the flame-only setting far more than they realize. On evenings above 65°F, or in rooms that hold heat well, the 750-watt setting delivers the full visual experience of a fireplace at exactly half the electricity consumption of full heat mode.

A wall-mounted electric fireplace running on flame-only for four hours consumes 3 kWh, less than a single cycle of a dishwasher. The same unit on full heat for the same four hours draws 6 kWh. Over a month, the choice between those two settings determines whether the unit adds $8 or $32 to the utility bill.

Some linear electric fireplaces also offer a mid-range 1,000-watt setting, which suits rooms that need light supplemental heat rather than primary heat output. Most electric fireplaces include a thermostat, so the unit does not run at 1,500W continuously even when heat mode is active. In a well-insulated room, a thermostat-controlled unit may cycle off for 15 to 30 minutes of every hour, reducing actual energy consumption well below the rated maximum.

Zone Heating vs. Running Your Whole Home

The comparison that actually justifies an electric fireplace from a cost perspective is not electric fireplace vs. space heater. It is heating one room vs. heating the whole house.

Central heating in a typical US home costs between $0.60 and $1.10 per hour on natural gas, based on average consumption data from the U.S. Department of Energy. That range covers 1,500 to 2,500 square feet of conditioned space. Running the whole-house system to heat rooms that are not being used is a straightforward waste when the goal is comfort in one room.

An electric fireplace heating a single room at $0.27 per hour, with the thermostat for the rest of the house dropped to 62°F, costs significantly less per hour and delivers the heat exactly where it is needed. The savings are proportional to how many rooms are not being heated and how wide the thermostat setback is.

This is why natural gas fireplaces and vent-free fireplaces are also positioned as zone heating solutions. Electric models remove the installation cost, the venting requirement, and any fuel supply consideration entirely. The tradeoff is that electricity costs more per BTU than natural gas in most markets, which is why thermostat cycling behavior matters so much to long-term operating cost.

Electric Fireplace Monthly Cost by Usage Pattern

The table below shows pre-calculated monthly costs at three electricity rates across the three most common daily usage patterns. All calculations assume the full 1,500-watt heat setting. For flame-only mode at 750W, halve every figure.

Source: EIA May 2026 residential electricity rates. Calculations assume a 30-day month and continuous 1,500W draw with no thermostat cycling. Actual costs are typically 20 to 40% lower with thermostat control active.

Dimplex models, including the Revillusion series, include a programmable thermostat with setback scheduling. This is the most effective single feature for reducing operating costs on any electric fireplace used more than two hours per day. Setting a 2-hour timer for the heating element while keeping the flame effect on covers most evening use cases at the 750-watt cost rather than 1,500 watts for the full session.

Frequently Asked Questions

How much does it cost to run an electric fireplace per hour?

At the national average of $0.18 per kWh, a 1,500-watt electric fireplace costs approximately $0.27 per hour on full heat. On the 750-watt flame-only setting, that drops to $0.14 per hour. Rates in Hawaii reach $0.52 per kWh, which roughly doubles those figures.

How much electricity does an electric fireplace use per month?

A 1,500-watt fireplace running 3 hours daily consumes 135 kWh per month. At the US average of $0.18 per kWh, that adds approximately $24.30 to a monthly utility bill. Reducing to 1 hour per day drops consumption to 45 kWh and monthly cost to roughly $8.10.

Are electric fireplaces expensive to run?

Electric fireplaces cost $0.14 to $0.27 per hour at US average electricity rates, comparable to a standard 1,500-watt space heater. That is less per hour than central heating, which averages $0.60 to $1.10 per hour to warm an entire home on natural gas.

Is an electric fireplace cheaper to run than central heating?

Zone heating one room with an electric fireplace at $0.27 per hour costs less than running central heating at $0.60 to $1.10 per hour for an entire home. The savings increase with the number of rooms not being heated at the same time.

How many watts does an electric fireplace use?

Most electric fireplaces operate at two settings: 750 watts for flame effect only and 1,500 watts for full heat output. Some models include a 1,000-watt mid-range setting. The wattage is printed on the back label or listed in the product specifications.

Does an electric fireplace use a lot of electricity compared to a space heater?

A 1,500-watt electric fireplace draws the same power as a standard space heater at maximum output. Both consume 1.5 kWh per hour. Electric fireplaces typically run a thermostat cycle rather than continuously, which reduces actual average consumption below the rated maximum.

What is the average monthly cost of running an electric fireplace?

Monthly cost ranges from $8 to $81 depending on usage hours and electricity rate. At 1 hour per day on full heat, expect $8 to $12. At 3 hours, $24 to $36. At 8 hours, $65 to $97. Use the calculator above with your local rate for a precise estimate.

Conclusion

For buyers comparing electric to gas, the cost-per-hour difference narrows significantly once installation costs are factored in. Electric models require no gas line, no venting, no chimney inspection, and no annual service, making the upfront and ongoing cost comparison more favorable than the per-hour electricity math alone suggests.

Wall-mounted electric fireplaces and double-sided fireplace designs can serve two rooms simultaneously, which changes the cost-per-room calculation compared to a single-zone space heater. For open-plan living spaces where the fireplace is visible from both the living area and dining room, that counts as zone heating two spaces for the same power draw.
