An electric fireplace usually draws about 12.5 amps on a 1,500 W setting and costs about 26 cents an hour at 17 cents per kWh. Drop to 750 W and the load falls to about 6.25 amps, which is why the setting matters more than the flame effect.
Say your den is 14 by 18 feet, the fireplace is running most evenings, and the utility rate is 17 cents per kWh. A 1,500 W setting uses 1.5 kWh per hour, so 4 hours a night is 6 kWh and about $1.02 a night before you count the rest of the house.
That is the part people miss. The flame looks expensive; the heater is what moves the meter.
Key takeaways
A 1,500 W electric fireplace draws about 12.5 amps on 120 volts.
At 17 cents per kWh, 1,500 W costs about 26 cents an hour to run.
The 750 W setting cuts the draw to about 6.25 amps and roughly half the running cost.
Electric fireplaces do not need a chimney or vent, but the outlet and breaker still matter.
A thermostat, timer, or lower-watt setting saves more than decorative flame changes.
Electric Fireplace Amp Usage Explained
Electric fireplace amp usage is usually 12.5 amps at 1,500 watts on a 120-volt outlet; 1,000 watts uses about 8.3 amps, and 750 watts uses about 6.25 amps. The amps needed for an electric fireplace come from its heater wattage, so a 1,500-watt unit can use a standard 15-amp circuit by itself, while other devices on that circuit may overload it.
12.5 A
1,500-watt fireplace at 120 V
The basic calculation is watts ÷ volts: 1,500 ÷ 120 = 12.5 amps. A 750-watt setting draws about 6.25 amps, and a 1,000-watt setting draws about 8.3 amps.
If “electric fireplace replace amp” means replacing the circuit breaker, don’t install a larger breaker to solve an overload. First identify what else shares the circuit, and plug the fireplace directly into a wall outlet rather than an extension cord or power strip. A 15-amp circuit has only about 2.5 amps left after a 1,500-watt fireplace starts, so a vacuum, lamp, or other heater can trip it.
For electric fireplace running costs, convert watts to kilowatts, multiply by hours, then multiply by your electricity rate: watts ÷ 1,000 × hours × price per kWh. At 1,500 watts for four hours and 17 cents per kWh, the arithmetic is 1.5 × 4 × $0.17, or $1.02 for that evening.

Worked example
Say your 12 by 14 foot living room uses the fireplace heater for four hours a night on 26 nights. At the full 1,500-watt setting, it uses 1.5 kW × 4 × 26 = 156 kWh, costing about $26.52 at 17 cents per kWh. The same schedule at 750 watts uses half as much electricity, about 78 kWh, or $13.26.

Schedule4 hours × 26 nights
Full-heat use156 kWh
Flame-only mode
The flame effect uses far less power than the heater, but it isn’t the heating load. A realistic log set doesn’t change the electric fireplace amp usage; the heater’s wattage does. At full heat, the unit uses 1.5 kilowatts, or 1.0 kilowatt at a 1,000-watt setting and 0.75 kilowatt at 750 watts.
Electric Fireplace Running Costs Compared With Other Heaters
An electric fireplace usually costs about 26 cents an hour at 1,500 W and $0.17 per kWh, roughly the same electricity cost as a 1,500 W oil-filled heater. A plug-in fireplace is usually a 120 V supplemental heater; propane, kerosene, and pellet heaters add fuel handling, combustion, venting, and storage concerns.

Illustrative comparison; actual fuel burn rates and prices vary by heater, setting, and location.
Fuel math is just as checkable: gallons burned per hour × hours × price per gallon, or pounds burned per hour × hours × price per pound. A propane heater using 0.10 gallon an hour for eight hours burns 0.8 gallon; at $3 per gallon, that is $2.40 for the night before any ventilation or installation costs.
Myth
A decorative flame setting costs the same as running the heater.
Fact
The flame effect can use far less electricity than the heating element, depending on the model. Flame-only mode normally avoids the large wattage draw; check the manual for its listed watts. Electric fireplace logs, an electric fireplace with logs, and a mantel model change the appearance and installation, not the cost formula, unless they change the wattage.
The best electric fireplace logs or best electric fireplace with mantel depend on the space, controls, and heat output rather than the word “best” on the box. Duraflame electric fireplaces follow the same wattage rule: find the heat setting’s watts, divide by 1,000, then multiply by your hours and electric rate. For another plug-in comparison, see oil-filled heater electricity usage.
In short
Electric fireplaces direct their cost through the meter, while fuel heaters charge you through both fuel use and the equipment needed to burn it safely. Compare the actual wattage or burn rate, not the decorative logs or mantel.
Electric Fireplaces Do Not Require A Chimney
An electric fireplace does not need a chimney, flue, or vent because it doesn’t burn fuel. The answer is the same for an insert, wall-mounted unit, log set, or mantel model; only the installation and clearances change.
How To Turn On An Electric Fireplace
To turn on an electric fireplace, use the main power control, select heater mode, and set the thermostat or heat level; the remote may provide the same controls. Flame-only mode runs the visual effect without the heater, so turning on the flame is not the same as turning on heat. A timer can shut the unit off later, while the thermostat cycles heat to maintain its setting.
For how to light an electric fireplace, there is no pilot to light: restore power, press the main power button, and follow the model’s control sequence. The electric fireplace controls may be on the top panel, behind a small access door, or on the remote.
Height, Placement, And Basic Checks
An electric fireplace height guide should start with the viewing position and the manual’s clearance instructions, because mounting it too high can make the heat feel useless while blocking the outlet or intake can restrict airflow. Height changes comfort and airflow; wattage and runtime still determine the bill.
Where Is The Fuse?
If the unit has a replaceable fuse or reset, its location is model-specific—often behind a control panel or near the power inlet. Check the owner’s manual before opening anything.
Stop If Power Looks Unsafe
If the fireplace won’t heat, check that the outlet has power, the breaker hasn’t tripped, and the built-in fuse or reset is covered by the manual. Don’t bypass a fuse or open live electrical parts. A damaged cord, repeated breaker trips, or burnt smell means unplug it and call a qualified service professional.
How To Cut Electric Fireplace Costs Fastest
The fastest saving is switching from 1,500 W to 750 W, which cuts the fireplace’s heating electricity roughly in half. At the same 17 cents per kWh, eight hours costs about $2.04 at 1,500 W and about $1.02 at 750 W.
1
Use the lower heat setting
Run 750 W when the room only needs a little help. Flame brightness and color usually affect appearance far more than the heating bill, while the heat setting controls the large electrical load.
2
Limit run time
A thermostat or timer keeps the heater from warming an empty room. Set the timer for the hours you occupy the room rather than letting the fireplace run from breakfast to bedtime.
3
Heat one zone
Use the fireplace where you’re sitting and turn the central thermostat down a few degrees, if the rest of the household is comfortable. Zone heating works best with a closed room and an open path for warm air.
4
Hold the heat
Close doors, draw curtains after sunset, and seal obvious drafts around windows and doors. A room that loses heat slowly lets the fireplace cycle off sooner.
If you want both 750 W and 1,500 W modes plus a timer in a new unit, Product 1 gives you those controls and is listed for supplemental zone heating up to 400 square feet.
If you need lower and full heat modes
R.W.FLAME 30 inch Recessed and Wall Mounted Electric Fireplace
Product 1 switches between 750 W and 1,500 W and includes a timer, so you can reduce the load instead of running full power every time. It won’t fix a drafty room or make a shared circuit safe.
Paint changes the look, not the wattage: you can paint a cabinet surround or wall with paint suited to that surface, but don’t paint the heater, glass, vents, grille, or controls unless the manual allows it. A decorative electric fireplace can show flames without heat; an in-cabinet or built-in model still needs its specified airflow and clearances. There is no universal electric fireplace height, so follow the installation instructions and keep the outlet, controls, and air openings accessible.
Check the circuit before blaming the heater
Plug an energy meter directly into the wall outlet and check the fireplace at each heat setting. The reading can confirm whether the unit is near 750 W or 1,500 W, but don’t use a meter, extension cord, or power strip as a reason to ignore a hot plug or tripping breaker.
What To Do Next For Your Room Or Circuit
Start with the nameplate and the outlet, then decide whether the unit is worth keeping; five checks will remove most of the guesswork.
1
Read the nameplate
Confirm whether the fireplace is rated for 750 W, 1,500 W, or another load. Use the actual rating for your cost and amp calculation rather than the marketing description.
2
Check the circuit
Identify whether the outlet is on a 15 A circuit and what else shares it. A 1,500 W heater draws about 12.5 A at 120 V, leaving little room for another heavy load.
3
Stop at warning signs
If the breaker trips, the cord runs hot, or the plug fits loosely, stop using the fireplace. Have an electrician check the outlet and circuit; don’t defeat the breaker or keep resetting it.
4
Compare the useful features
For a replacement, compare wattage, timer, thermostat, physical fit, and required clearances before flame style. If you need a remote or control for an electric fireplace, match it to the exact model rather than assuming a universal control will work.
5
Judge the repair
A purely decorative unit may not justify an expensive control-board repair, especially when it’s older. Replace it only after confirming the new unit fits the opening and has the heat settings you need.
If you’re replacing an older unit
R.W.FLAME 30 inch Recessed and Wall Mounted Electric Fireplace
Product 1 offers 750 W and 1,500 W settings, a timer, touch controls, and a remote. Check its 30-inch width and installation depth against your opening before buying.
An electric fireplace cable UK search needs a separate check: a US unit and plug aren’t made safe by adding a travel adaptor or swapping the cable. If you meant voltage by “voltorb,” read the nameplate and use a qualified electrician for any supply change.
In short
Measure the nameplate load, inspect the 15 A circuit, and stop immediately for heat, looseness, or trips. Buy by wattage and fit first; flame effects can wait their turn.
Frequently Asked Questions
How many amps does a 1,500 watt electric fireplace use?
A 1,500-watt electric fireplace uses about 12.5 amps on a 120-volt circuit. Check the nameplate because some units include a separate heater and flame-only mode, and the heater is what creates the larger load.
Does an electric fireplace need a chimney or vent?
No, an electric fireplace needs no chimney, flue, or combustion vent. Keep its air inlets and outlets clear, since the built-in heater still needs airflow to avoid overheating.
How do you turn on an electric fireplace?
Use the power button on the unit or its remote, then select the heat setting separately from the flame effect. If the remote fails, check its batteries and try the control panel; the exact button sequence belongs to the model’s manual.
Where is the fuse for an electric fireplace?
The fuse may be inside the fireplace behind an access panel, while some models rely on the home’s circuit breaker instead. Unplug the unit before inspecting anything, and replace a fuse only with the same type and rating; repeated failures need service rather than a larger fuse.
Can you paint an electric fireplace?
You can usually paint a fixed surround or mantel if the manufacturer’s instructions allow it, but don’t paint the insert, heating outlet, controls, glass, or vents. Disconnect power first and keep paint, dust, and coverings away from the heater’s airflow paths.
