Many electric heaters distribute heat through air circulation; they heat the indoor air. But that’s not the case of electric radiant panels, installed on walls or ceilings. Radiant panels are designed to heat people in their line of sight, not the air.
They are like ceramic, quartz and other infrared small heaters, intended for spot and personal heating; the difference is in their placement on the walls or on the ceiling, and in their larger surface and capacity.
FACTS on Radiant heating panels for ceilings and walls..
»» are designed to heat people in their line of sight;
»» have very quick response times;
»» are excellent for selective heating (zone heating);
»» do not provide even temperatures through the room;
»» can provide high energy savings if turned off whenever people leave the rooms.
What are radiant heat panels?
Most radiant ceiling panels consist of a high-density insulation board (fiberglass) and an electric resistance. Some are made of smooth faced steel or aluminum.
Electric radiant panels do not require blowers, ducts, filters or flues. Installation is easy (it's almost like installing a fluorescent light system).
They operate at a temperature range of 150-170°F.

Radiant Heat ceiling and wall Panels - Brands and Manufacturers
Here is a small list with some of the top radiant heat panel manufacturers:
Electric radiant heaters offer a very quick response time. They can heat almost instantaneously the people in their line of sight, close enough to them, which is a big advantage for energy savings, as long the heater is controlled by occupancy sensors and thermostats, or people turn the panels on and off as they enter or exit the room.
Basic FACTS on Radiant Heating for ceilings and walls
1) They heat people, not the air in the room;
2) They are un-obstructive;
4) They have a quick heat response time;
5) Size: often
between 1 x 2 and 4 x 8 feet;
6) Powered by 120 or 240-Volt electrical current;
7) Improperly used they will not provide energy savings
8) They do not provide even room temperatures.These heaters haven't any inherent technological advantage over other electric-resistance heating units of radiant type. Their technology is that of electric-resistance heaters; radiant panels will not provide any significant energy savings if improperly used. They must be turned off in unoccupied rooms.
Complaints about radiant heat panels
Radiant ceiling panels do not provide an even temperature, and their performance can be highly affected by their positioning on the ceilings and walls.
Do not expect even temperatures through the entire room.
The heaters are designed to heat people in their line of sight, not the room. Some people often complain about cold spots in the room (due to the fact that the heat coming from the panels declines with the distance), or of overheated spots.
Some manufacturers claim electricity savings of 30%, 40% or 50% when compared with other electric heating systems. But that's mostly a claim. It depends a lot on how the equipment is used, and the intended goals.
radiant ceiling Panels are inexpensive
Expect prices between $150 to $500 per panel/room… Installation is simple and inexpensive: panels come pre-assembled.
