Electric Fireplace Wattage: What It Means and Why It Matters

Electric wattage is the amount of power an electric device consumes. In simpler words, watts are equivalent to how fast electricity is being used to produce the required energy in a specific time. So higher the watts, the more electricity a device needs to run smoothly. 

Now, within an electric fireplace itself, the amount of total electricity consumed largely depends on its functions. For instance, if you only turn on the flames, which are created by the LED lights inside without the actual heat, the power consumed would be as low as 10-60 watts. 

However, the heating element naturally uses about 750 watts or more, which is a lot of power. It takes a larger amount of energy to produce heat than to make light. While the flame effect is created with small lights, heat is produced when electricity flows through the metal wire inside a fireplace, causing it to become hot. 

Once the wire is hot, a fan blows air over it, thus spreading warm air into the room. Therefore, turning on an electric fireplace heater frequently is bound to cost you more in the electricity bill.

Electricity Costs in the U.S. and What They Mean for Electric Fireplaces

In order to understand how much it costs to run an electric fireplace on a daily basis or even occasionally, we need to look at the electricity cost in different regions and how it affects your consumption. In the US, the average cost of electricity is 15 to 18 cents per kilowatt-hour (kWh). 

Kilowatt (kW) = How much power a device uses at a given time

Hour (h) – How long the device runs. 

So, 1kWh coverts to 1,000 watts for 1 hour. 

According to the official site of the US Energy Information Administration, the average price of electricity for residential use is highest in Connecticut, costing 30.48 cents per Kwh as of September 2025.  Whereas, Nevada residents pay the least at 11.95 cents per Kwh. 

How to Calculate Electric Fireplace Electricity Costs

The electricity cost of any electric fireplace is calculated using these factors:

• Wattage of the fireplace – This tells how much power a specific model of fireplace uses. It can vary largely depending on the specific design’s power rating, size, heat settings and efficiency. 
  
  
• How many hours has it run – This is self-explanatory. The longer a fireplace is plugged into a power source, the more electricity it consumes. It further depends on the feature – non-heat flames consume less power, while the heating needs more. 
  
  
• Your electricity rate – You can check the average electricity cost in your region and accordingly calculate how much it would cost for specific hours, days or in a month. 

Example formula:

Electricity Cost = Power Consumption (kW) × Hours of Use × Electricity Rate ($/kWh)

For instance, if the average electricity cost in your region is 15 cents kWh, then using an electric fireplace of 750 Watts with the low to medium heating for four hours would cost you:

Power: 750 W = 0.75kW
Time: 4 hours 
Energy consumed for four hours: 0.75 kW × 4 h = 3.0 kWh
Total Cost: 3.0 kWh × $0.15/kWh = $0.45

However, only the fake flames created with LED lights, which use about 10 watts, for the same amount of time, would cost:

Power: 10 W = 0.01kW
Time: 4 hours 
Energy consumed for four hours: 0.01 kW × 4 h = 0.004 kWh
Total Cost: 0.04 kWh × $0.15/kWh = $0.006

The standard formula is used to calculate electricity costs for fireplaces of various capacities, as specific models and functions consume different amounts of power.

Overnight Electric Fireplace Real Costs Explained

During winter, an electric fireplace is typically used to spread warmth, aside from enhancing the visual appeal of your personal space. Here’s how much it would cost you on average to run a fake fireplace overnight, for both heating and in the flame-only mode. 

Typical power draws for both modes:

Heat on high: Approximately 1,500 watts (1.5 kW)
Heat on low: Approximately 750 watts (0.75 kW)
Flame only:  Approximately 50–300 watts (0.05–0.3 kW)

Electric Heater vs Flame-Only Overnight Cost 

An electric fireplace, regardless of where it is installed in your house or any other space, needs to run for 10 to 12 hours in winter for uninterrupted warmth and heat. Let’s calculate how much you would pay from your pocket if you used the heating device for an entire night in your region, with an average electricity cost of 17.5¢/kWh. 
An electric fireplace that runs at about 1500 watts on high heat for 10 hours would cost you:

• 1.5 kW × $0.175 × 10 hrs ≈ $2.63 per night or $0.26 per hour. 

The same device, when run on lower heat, that is at about 750 watts for the same duration, could cost you nearly half the cost of the other mode:

• 0.75 kW × $0.175 × 10 hrs ≈ $1.31 per night or $0.13 per hour. 

However, the fireplace needs very little electricity to run in the flame-only mode. If it’s only used for the cosy flames without heat, the LED lights draw very little power, usually under 300 W. Per night, it could cost you:

• 0.1–0.3 kW × $0.175 × 10 hrs ≈ $0.18–$0.53 per night. 

The flame-only mode makes a fake fireplace highly affordable, even if it is left on overnight for ambience.

Fake Fireplace Electricity Cost Breakdown for 3, 6 and 8 hours in Winter 

1. 3-Hour Overnight Run

1.5 kW × 3 hours × $0.17/kWh ≈ $0.77 – This is just enough for early evening warmth or mild heating before you hit the sack. 

2. 6-Hour Overnight Run

1.5 kW × 6 hours × $0.17/kWh ≈ $1.53 – Ideal to heat one room before bedtime, compared to central heating, which may not be within everybody’s dollar range. 

3. 8-Hour Overnight Run

1.5 kW × 8 hours × $0.17/kWh ≈ $2.04 – In peak winter, when you need to run the heater throughout an 8-hour sleep period, the cost would be a little over $2 per night. 

Mind you, the above figures are rough averages, as the electricity cost per night or specific hours while running an electric fireplace can be high or lower depending on your region.

Is an Electric Fireplace Expensive to Run in Winter? Power Usage Explained

From the calculations so far, it’s safe to say the overall power usage of a fake fireplace in either mode isn’t as expensive as some people may assume. In fact, even after running it for long hours in peak winter, the daily average cost, about $1 to $2 per night, would be less than or roughly equal to a single cup of coffee. 

Furthermore, if you have a model with the thermostat or auto-cycling feature, then your heater wouldn’t be running at full 1,500 watts continuously. It will cycle on and off to maintain the desired temperature, without excessive power usage. In fact, it’s believed to cut the actual cost further. 

Compared to a central electric furnace or baseboard system, an electric fireplace, often used as supplemental or zone heaters, doesn’t draw much energy. Most models use between 750 watts and 1,500 watts when the heater is turned on. Which means one hour of heat costs roughly the same as boiling a big pot of water.

Do Electric Fireplace Types and Designs Affect the Cost?

There are various types of electric fireplaces depending on their style and design. While the upfront cost and installation inevitably vary for different models, there isn’t a big difference in their running costs. The power usage mostly depends on the heater’s wattage. 

The main types of electric fireplaces include:

Freestanding Units – These standalone heaters just need to be plugged in and placed against a wall. It’s easy to set up without professional help. A freestanding electric fireplace is also a budget-friendly option, with most models priced between $200 and $800.

Wall-Mounted Fireplaces – A perfect blend of style and function, a wall mounted fireplace is a great choice for modern spaces and saves space on the floor, such as the ones Garvee offers. It is directly mounted on the wall like a TV set. Depending on its style and smart features, a wall-mounted fireplace can start with an average price of $300 and go up to $2000. 

Built-in Fireplaces – Also known as recessed fireplaces, this model is installed into a wall with the help of a professional, so its overall cost is higher than the others. It looks like a part of the architecture, instantly uplifting the overall appeal of your place and making the integration look modern and realistic. Most modern homes use an electric fireplace TV stand, which combines a media console for your TV with a built-in electric fireplace. Some smart electric fireplaces allow you to control their features remotely by connecting Wi-Fi. 

Corner Electric Fireplaces – In compact places, such as a small office or a studio apartment, where floor space is limited, a corner electric fireplace fits perfectly. These heating devices are usually triangular or wedge-shaped, so they nestle neatly into a 90° corner, offering a finished look. You don’t need an external installation. Anyone can tuck the unit into a corner and still enjoy the flame view and heat. Corner electric fireplaces also don’t cost much, with basic models selling anywhere between $200 to $500, whereas the high-end units are costlier.  

Tips to Reduce Running Costs

Electric fireplaces aren’t expensive to run if you know how to use them smartly. These tips can help you significantly reduce your overall electricity cost. 

1. Use it as a zone heating, rather than your entire home. Heating one room at a time and lowering your central thermostat by 1–3°F can lead to a noticeable difference in your electricity bill. 

2. Always ensure the auto mode is on in models that come with the feature. This prevents the unit from overrunning and uses the heater depending on the temperature of the room. So you won’t be using as much power as you would by keeping the heat on all night.

3. Choose a low heat setting as much as possible, unless high heat is an absolute necessity. Just the switch from high heat to low heat setting can cut your electricity use roughly in half. 

4. If your fireplace doesn’t come with an auto mode, set a timer and only use that many hours to heat your room. It can be turned off when there is enough warmth, instead of letting it run for an entire sleep cycle. 

5. You can naturally reduce your dependency on an electric fireplace by improving the insulation of your room. It also reduces the heating time, thus burning less energy. Simple steps such as keeping the doors closed to unused rooms, sealing drafts around windows and doors, and even closing curtains or blinds at night can make a huge difference. 

6. Make sure your fireplace matches the size of your room. A device too big or too small leads to inefficient heating and uses more power to run. It is also advised to plug the fireplace directly into the wall outlet, instead of using an extension cord, as the former ensures efficient power delivery. 

7. Last but not least, invest in quality products, such as the GARVEE electric fireplaces, that deliver performance within your budget and contribute to a reduction in your electricity with their enhanced features. 

An electric fireplace is a great choice to stay warm and comfortable in winter, without splurging on expensive heating devices for your home, office or even outdoor spaces. Thanks to the flame-only mode, you can use the same heater to decorate your personal space in seasons that don’t warrant external heating. A fake fireplace is for those who value ambience, comfort needs and budget. 

If you are ready to update your space, don’t wait. Explore the GARVEE electric fireplaces for stylish and affordable units that keep you warm, while adding a modern edge to your home all year round.
