Infrared heaters typically cost between $0.10 to $0.30 per hour to run, depending on the wattage of the unit and local electricity rates, making them an efficient heating option for targeted warmth in specific areas.
Infrared heaters cost $0.10–$0.20 per hour to run, making them one of the most energy-efficient heating options available. Unlike traditional heaters that warm the air, infrared models heat objects directly – cutting energy waste while keeping you comfortably warm.
How Much Does It Cost to Run an Infrared Heater?
The operating cost of infrared heaters depends on three key factors:
- Wattage: Most models range from 300W to 1500W
- Electricity rates: Average $0.13 per kWh in the US
- Usage time: Hours used per day
Infrared Heater Running Cost Calculator
Use this simple formula:
Heater Wattage × Hours Used × Electricity Rate = Daily Cost
| Heater Size | 1 Hour Cost | 8 Hours Cost |
|---|---|---|
| 500W | $0.07 | $0.52 |
| 1000W | $0.13 | $1.04 |
| 1500W | $0.20 | $1.56 |
For comparison, oil-filled radiators typically cost 20-30% more to operate than infrared models of similar wattage.
Why Infrared Heaters Are More Efficient
Direct Heating Technology
Infrared heaters work like the sun – they emit electromagnetic waves that warm objects and people directly rather than heating the air. This means:
- No heat loss through drafts or ventilation
- Immediate warmth (no waiting for air to circulate)
- More consistent temperatures throughout the room
According to U.S. Department of Energy, radiant heaters can be more efficient for spot heating than conventional space heaters.
Lower Operating Temperatures
Because infrared heat feels warmer than air temperature, you can set your thermostat 5-10°F lower while maintaining comfort. Each degree lowered saves about 3% on heating costs.
No Duct Losses
Unlike central heating systems that lose 20-30% of heat through ducts, infrared heaters deliver 100% of their energy directly where needed. This makes them particularly efficient for heating single rooms.
Factors Affecting Infrared Heater Efficiency
1. Installation Location
Mounting height and angle significantly impact performance:
- Wall-mounted at 7-8 feet for optimal coverage
- Ceiling-mounted for whole-room heating
- Avoid placing behind furniture or in corners
2. Room Insulation
While infrared heaters perform better than convection heaters in drafty spaces, good insulation still matters:
- Well-insulated rooms need 20-30% less wattage
- Consider adding thermal curtains in older homes
3. Thermostat Use
Smart thermostats can reduce running costs by 10-15%:
- Programmable models maintain ideal temperatures
- Wi-Fi enabled units allow remote control
- Occupancy sensors prevent heating empty rooms
Infrared vs Other Heating Options
| Heater Type | Cost per Hour | Efficiency | Best For |
|---|---|---|---|
| Infrared | $0.10-$0.20 | 100% | Spot heating, outdoor areas |
| Ceramic | $0.12-$0.25 | 85-90% | Small rooms |
| Oil-filled | $0.15-$0.30 | 80-85% | Continuous heating |
| Central Gas | $0.30-$0.50 | 70-80% | Whole-house heating |

Tips to Reduce Infrared Heating Costs
1. Right-Size Your Heater
Calculate your room’s square footage and choose appropriate wattage:
- 100-150W per square meter (10-15W per sq ft)
- Higher wattage for rooms with high ceilings
2. Use Zone Heating
Only heat occupied rooms rather than your entire home. The ENERGY STAR program estimates this can save up to 30% on heating bills.
3. Maintain Optimal Temperature
Set your thermostat to 68°F when awake and lower when sleeping or away. Each degree above this adds about 3% to your heating costs.
4. Regular Maintenance
Keep reflectors clean and check electrical connections annually to maintain peak efficiency.
Long-Term Cost Savings
While infrared heaters have higher upfront costs than some alternatives, their energy efficiency leads to significant savings:
- 30-50% cheaper to run than conventional electric heaters
- Lasts 2-3 times longer than ceramic heaters (average 5-7 year lifespan)
- No moving parts means minimal maintenance costs
For large spaces or whole-house heating, consider pairing infrared panels with a propane tankless water heater for maximum energy efficiency.
