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
