How Much Electricity Does an Electric Fireplace Use?

Introduction: Electric fireplaces offer the ambiance of a traditional fireplace without the hassle of wood or gas, but many homeowners wonder about their electricity consumption and operating costs. Understanding how much power these units use helps you make informed decisions about heating your home efficiently and economically.

Electric Fireplace Power Consumption Basics

Standard Wattage:

Most electric fireplaces operate at consistent power levels:

• Flame Effect Only: 50-150 watts (similar to light bulbs)
• Low Heat Setting: 750 watts
• High Heat Setting: 1,500 watts (standard maximum)
• Average Usage: 1,500 watts when heating

Why 1,500 Watts?

This is the maximum wattage for devices plugged into standard 120-volt household outlets (15-amp circuit). Higher wattage would require dedicated circuits.

Calculating Electricity Costs

Cost Formula:

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

Example Calculations:

Scenario 1: Flame Effect Only (No Heat)

• Power: 100 watts
• Usage: 4 hours per day
• Electricity Rate: $0.13 per kWh (US average)
• Calculation: (100 ÷ 1,000) × 4 × $0.13 = $0.052/day
• Monthly Cost: $1.56
• Annual Cost: $18.98

Scenario 2: High Heat Setting

• Power: 1,500 watts
• Usage: 4 hours per day
• Electricity Rate: $0.13 per kWh
• Calculation: (1,500 ÷ 1,000) × 4 × $0.13 = $0.78/day
• Monthly Cost: $23.40
• Annual Cost: $284.70

Scenario 3: Moderate Use (2 hours/day heating)

• Power: 1,500 watts
• Usage: 2 hours per day
• Electricity Rate: $0.13 per kWh
• Calculation: (1,500 ÷ 1,000) × 2 × $0.13 = $0.39/day
• Monthly Cost: $11.70
• Annual Cost: $142.35

Your Electricity Rate:

Check your utility bill for your actual cost per kWh, which varies by location:

• US Average: $0.13 per kWh
• Range: $0.09 - $0.30+ per kWh
• Peak vs. Off-Peak: Some areas have time-of-use rates

Heating Capacity and Coverage

Standard Heating Output:

• BTU Output: 4,600-5,200 BTUs at 1,500 watts
• Coverage Area: 400-500 square feet
• Best Use: Supplemental zone heating
• Temperature Rise: 10-15°F in covered area

Heating Efficiency:

• Conversion Rate: Nearly 100% of electricity converts to heat
• No Heat Loss: Unlike vented fireplaces, all heat stays in room
• Instant Heat: No warm-up time required
• Targeted Heating: Heat only rooms you're using

Cost Comparison: Electric Fireplace vs. Other Heating

Electric Fireplace (1,500W):

• Cost per Hour: $0.195 (at $0.13/kWh)
• Efficiency: 100% (all electricity becomes heat)
• Installation: Plug-in, no installation cost
• Maintenance: Minimal

Central Heating (Natural Gas):

• Cost per Hour: $0.50-$1.50 (whole house)
• Efficiency: 80-95%
• Installation: $3,000-$7,000+
• Maintenance: Annual servicing required

Space Heater (1,500W):

• Cost per Hour: $0.195 (same as electric fireplace)
• Efficiency: 100%
• Installation: Plug-in
• Aesthetics: Utilitarian, no ambiance

Wood-Burning Fireplace:

• Cost per Hour: $1-$3 (wood costs)
• Efficiency: 10-30% (most heat lost up chimney)
• Installation: $2,000-$10,000+
• Maintenance: Chimney cleaning, ash removal

Factors Affecting Operating Costs

Usage Patterns:

• Hours per Day: More use = higher costs
• Heat vs. Flame Only: Flame effect uses minimal power
• Thermostat Setting: Lower temps reduce runtime
• Seasonal Use: Winter months increase usage

Room Characteristics:

• Insulation Quality: Better insulation = less runtime
• Room Size: Larger rooms require more heating
• Ceiling Height: Higher ceilings increase volume to heat
• Windows/Doors: Drafts increase heating needs
• Climate: Colder regions require more heating

Unit Features:

• Thermostat: Cycles on/off to maintain temperature
• Timer: Automatic shutoff saves energy
• Multiple Heat Settings: Low setting uses half the power
• LED Flames: More efficient than older technology

Energy-Saving Tips

Optimize Usage:

• Zone Heating: Heat only occupied rooms
• Lower Thermostat: Reduce central heat, use fireplace in main room
• Use Timer: Set automatic shutoff
• Flame Only: Use ambiance without heat when possible
• Proper Sizing: Match unit capacity to room size

Improve Efficiency:

• Seal Drafts: Weatherstrip windows and doors
• Add Insulation: Improve room insulation
• Use Ceiling Fan: Circulate warm air (reverse direction)
• Close Doors: Contain heat in room
• Lower Setting: Use 750W setting when sufficient

Strategic Timing:

• Off-Peak Hours: Use during cheaper electricity rates (if applicable)
• Supplement, Don't Replace: Use with central heat, not instead of
• Preheat: Warm room before occupying

Understanding Your Electric Bill Impact

Monthly Cost Scenarios:

Light Use (Ambiance Focus):

• Flame effect 4 hours/day: $1.56/month
• Heat 1 hour/day: $5.85/month
• Total: ~$7.50/month

Moderate Use (Evening Heating):

• Flame effect 2 hours/day: $0.78/month
• Heat 3 hours/day: $17.55/month
• Total: ~$18/month

Heavy Use (Primary Heat Source):

• Heat 8 hours/day: $46.80/month
• Total: ~$47/month

Seasonal Variation:

• Winter (Nov-Mar): Higher usage, increased costs
• Spring/Fall: Moderate usage for ambiance and occasional heat
• Summer: Minimal usage (flame effect only)
