How Much Does an Electric Fireplace Cost to Run?

Electric fireplaces offer a cozy atmosphere and supplemental heat—without the maintenance or emissions of wood or gas. But how much does it actually cost to run an electric fireplace? 

Whether you're comparing heating options or budgeting for winter, understanding your electric fireplace's energy usage is key. Let’s break down the real-world costs using wattage, kilowatt-hour (kWh) conversions, and national electricity rates. 

What Is the Typical Wattage of an Electric Fireplace? 

Most electric fireplaces—especially wall-mounted, built-in, or freestanding models—use around 1,500 watts (1.5 kW) when operating at full heat. This is similar to a space heater and is ideal for heating rooms up to 400 square feet. 

If you’re using only the flame effect (with no heat), the energy draw drops significantly to around 15 to 50 watts, depending on the model and LED technology. 

How to Calculate Electric Fireplace Energy Usage 

To calculate running costs, you’ll need two things: 

1. Wattage of your fireplace (typically 1,500W for heat mode) 
2. Your electricity rate, measured in kilowatt-hours (kWh) 

Here’s the formula: 

(Watts ÷ 1,000) × Hours Used × Cost per kWh = Operating Cost 
 

Example: 
If you use a 1,500W fireplace for 2 hours a day at the U.S. average electricity rate of $0.16/kWh: 

(1,500 ÷ 1,000) × 2 × $0.18 = $0.54/day 
 

National Average Electricity Rates 

Electricity rates vary by state, but as of 2025, the national average is approximately $0.18 per kWh (U.S. Energy Information Administration). Use your local utility rate for the most accurate estimate. 

Hourly, Daily & Monthly Cost Estimates

Estimates based on $0.18/kWh and full heat usage. 

Factors That Affect Operating Cost 

Several real-world factors can reduce or increase your fireplace’s energy cost: 

• Thermostat Settings: Using a built-in thermostat means the unit only runs when the room drops below your set temperature, lowering overall usage. 
• Flame-Only Mode: Running the flame effect without heat consumes minimal power—great for ambiance without the added cost. 
• Daily Usage Time: The longer it runs, the higher your bill. Consider using a timer or remote control to manage runtime efficiently. 
• Energy Efficiency: Some models are equipped with eco-modes or energy-saving LED flame technology that helps reduce consumption. 

Efficient Comfort You Can Control 

When compared to other heating options, electric fireplaces are among the most affordable and efficient supplemental heat sources—especially when used wisely. They're also 100% efficient at the point of use, meaning all the energy consumed goes directly into heating your space or providing ambiance. 

Whether you’re budgeting for winter or comparing heating alternatives, electric fireplaces give you total control over cost, comfort, and convenience.
