An electric fireplace typically uses between 750 to 1,500 watts, depending on the heat setting and model, providing efficient warmth for your space.
Electric fireplaces provide cozy warmth without the hassle of wood or gas. But how much electricity do they actually consume? Understanding their wattage helps you estimate operating costs and choose the right model for your needs.
How Many Watts Does an Electric Fireplace Use?
Most electric fireplaces use between 750–1,500 watts on average. The exact wattage depends on:
- Size and heating capacity
- Heat settings (low vs. high)
- Whether flame effects are used without heat
- Model efficiency
Smaller units may use as little as 500 watts on low settings, while larger models can reach 2,000 watts at maximum output. For comparison, this is similar to many smart space heaters.
Typical Wattage by Fireplace Type
| Fireplace Type | Wattage Range |
|---|---|
| Wall-mounted electric fireplace | 750–1,500W |
| Electric fireplace insert | 1,000–1,800W |
| Freestanding electric stove | 1,200–2,000W |
| Flame-only mode | 50–150W |
Calculating Electric Fireplace Operating Costs
To estimate your fireplace’s electricity costs:
- Check the wattage rating on your unit
- Divide by 1,000 to get kilowatts (1,500W = 1.5kW)
- Multiply by your local electricity rate (average $0.16/kWh)
- Multiply by hours of use
Example: A 1,500W fireplace used 4 hours/day at $0.16/kWh:
1.5kW × 4 hours × $0.16 = $0.96 per day or about $29/month
Cost-Saving Tips
- Use lower heat settings when possible
- Run flame effects without heat for ambiance
- Only heat occupied rooms
- Consider a wood-look electric stove for zone heating
Are Electric Fireplaces Energy Efficient?
Electric fireplaces convert nearly 100% of energy into heat, making them more efficient than:
- Wood fireplaces (10–30% efficient)
- Gas fireplaces (70–90% efficient)
According to the U.S. Department of Energy, electric resistance heating is 100% efficient at point of use. However, electricity generation at power plants averages about 33% efficiency.
BTU Output Comparison
Electric fireplaces produce about 3,413 BTUs per watt:
- 1,000W = 3,413 BTU
- 1,500W = 5,120 BTU
- 2,000W = 6,826 BTU
This makes them suitable for heating spaces up to 400 sq ft, similar to many propane space heaters.
Key Factors Affecting Electricity Usage
1. Thermostat Settings
Units with adjustable thermostats cycle on/off to maintain temperature, reducing runtime compared to continuous operation.
2. Insulation and Room Size
Well-insulated rooms retain heat better, allowing shorter run times. Oversized units waste energy in small spaces.
3. Usage Patterns
Daily use during winter months costs more than occasional holiday use. Zone heating can offset central heating costs.
Electric vs Other Fireplace Types
| Type | Efficiency | Avg. Operating Cost | Installation |
|---|---|---|---|
| Electric | 100% | $0.10–$0.30/hr | Plug-in |
| Gas | 70–90% | $0.30–$0.70/hr | Vent required |
| Wood | 10–30% | $1.50–$3.00/hr | Chimney required |
Electric models offer the easiest installation and precise temperature control, though fuel-based units often provide more intense heat.
