Radiant heat is transmitted through electromagnetic waves. When these waves are intercepted and absorbed they are converted into heat. The radiant energy is absorbed by objects in the room and warms the space similar to your clothes absorbing the light from the sun.

How does a radiated heating system work?

Radiant floor heating systems produce heat through thermal radiation. By heating the floor rather than the surrounding air, they provide indirect, diffused heat that radiates from the floor up. This heat is absorbed by surrounding objects, and they in turn help to warm the entire room.

Does radiant heat actually work?

Radiant heating has a number of advantages. It is more efficient than baseboard heating and usually more efficient than forced-air heating because it eliminates duct losses. ... Radiant floor heating systems are significantly different from the radiant panels used in walls and ceilings.
