Radiant heat (electromagnetic waves) does not require a medium. Sunlight, infrared light, microwaves are all radiant heat in the form of electromagnetic radiation.
Radiant heat does not require particles. It involves light in the infrared range.
radiant For one thing, it's how heat energy from the sun reaches us.
Radiant heat transmits in the form of waves.
In convection heat you heat the air first and then use the hot air to heat yourself. In radiant heat, the energy must be radiated directly from the heat element to your body. Note that radiant is much more directional.

Radiant heat is wonderful. It takes heat from an energy source--such as electrical coils in a ceiling--and warms the surrounding area gently. In the case of ceiling radiant heat, the warmth gradually spreads through the room. Radiant heating in a floor is a better choice because heat rises.
In my opinion, radiant heat is better than a traditional furnace. You have more control over how much heat you want, and where you want the heat. Using radiant heat is also more cost effective.
Heat Energy is one FORM of Radiant Energy...it is not different.
radiant heat.
The floor you can install on top of the radiant heat is Tile and hardwood floor.
The answer is no. Radiant ceiling heating does not work as well as radiant floor heating in that heat rises so having heat in the ceiling will not be as efficient as heating in the floor.
