The Complete Guide to Radiant Panel Heaters for Supplemental Heating


Ember Black Glass Radiant Panel Heater in Contemporary Living Room Setting

Radiant panel heaters deliver targeted, energy-efficient supplemental heat exactly where you need it—perfect for cold spots, chilly bathrooms, basements, home offices, and rooms that never quite warm up. Unlike traditional forced-air systems that circulate dust and allergens, radiant panels use infrared technology to warm people and objects directly, creating comfortable warmth without noise or air movement.

What Are Radiant Panel Heaters?

Radiant panel heaters are electric heating devices that use infrared technology to provide supplemental warmth in targeted areas.

Unlike conventional heating systems that warm the air, radiant panels emit infrared waves that directly heat people, furniture, and surfaces in the room. This creates a more comfortable, consistent warmth similar to the feeling of sunlight on your skin—without the drafts, noise, or dust circulation of forced-air systems.

Radiant panels are ideal for:

  • Cold spots: Rooms that never quite reach comfortable temperatures
  • Bathrooms: Quick warmth for morning routines without heating the entire house
  • Basements: Supplemental heat for finished lower levels
  • Home offices: Targeted comfort in workspaces
  • Additions: Efficient heating for sunrooms, converted garages, or new construction
  • Allergy sufferers: No air circulation means less dust and allergen movement

How Do Radiant Panel Heaters Work?

Radiant panel heaters use infrared technology to deliver warmth efficiently and comfortably.

The heating element inside the panel emits infrared radiation—the same type of heat you feel from the sun. These infrared waves travel through the air without warming it, instead transferring heat directly to solid objects and people in the room. Once these surfaces absorb the infrared energy, they gradually release warmth back into the space, creating a comfortable ambient temperature.

This direct heating method offers several advantages:

  • Faster warmth: You feel the heat almost immediately, rather than waiting for air to circulate
  • Energy efficiency: No energy is wasted heating air that rises to the ceiling or escapes through drafts
  • Consistent comfort: Eliminates cold spots and temperature fluctuations common with forced-air systems
  • Silent operation: No fans, blowers, or moving parts to create noise
  • Healthier air: No air circulation means less dust, allergens, and dryness

Operating Cost per Hour = (Wattage ÷ 1,000) × Electricity Rate

For example, an 800-watt Ember panel in an area with $0.15/kWh electricity costs:

(800 ÷ 1,000) × $0.15 = $0.12 per hour

Estimated Operating Costs for Ember Radiant Panels

Model Wattage Coverage Area Cost per Hour ($0.12/kWh) Cost per Hour ($0.15/kWh) Cost per Hour ($0.20/kWh)
Ember Glass/Mirror 600W 600W Up to 86 sq.ft. $0.07 $0.09 $0.12
Ember Glass/Mirror 800W 800W Up to 114 sq.ft. $0.10 $0.12 $0.16

Note: Actual costs vary based on insulation, ceiling height, outdoor temperature, and usage patterns. Panels controlled by thermostats or timers cycle on/off, reducing actual runtime and costs.

Cost-Saving Tips

  • Use programmable thermostats or timers: Set panels to lower temperatures when rooms are unoccupied, or schedule operation only during peak usage times
  • Zone your heating: Only heat rooms you're actively using
  • Improve insulation: Better insulation reduces runtime and energy consumption
  • Lower your central heat: Use radiant panels for supplemental warmth and reduce whole-home heating costs
  • Take advantage of off-peak rates: If your utility offers time-of-use pricing, run panels during cheaper rate periods

Choosing the Right Radiant Panel Heater

Selecting the appropriate radiant panel ensures optimal comfort and efficiency for your space.

Calculate Your Heating Needs

Start by determining your room's square footage and insulation quality. As a general rule:

  • Well-insulated rooms: 5–7 watts per square foot
  • Average insulation: 7–10 watts per square foot
  • Poor insulation: 10–12 watts per square foot

For example, a 100 sq.ft. room with average insulation needs approximately 700–1,000 watts of heating power. The Ember 800W panel is ideal for rooms up to 114 sq.ft., making it suitable for most residential supplemental heating applications.

Control Options

Choose between built-in thermostats, separate wall-mounted thermostats, timers, or smart thermostats that integrate with home automation systems. Programmable thermostats and timers offer the best energy savings by automatically adjusting temperatures based on occupancy and time of day.

Wattage and Coverage

Match the panel wattage to your room size and heating needs. It's better to slightly oversize than undersize—a larger panel running at lower intensity is more efficient and comfortable than a smaller panel running constantly at maximum output.
