"Radiant" sounds like "radiation", which should give you a clue. It travels at the same speed as any other electromagnetic radiation: the speed of light.
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.

Heat Energy is one FORM of Radiant Energy...it is not different.

An architect or an engineer is needed for the installation of radiant heating pads. Since each room has different requirements due to structure and space a professional is needed to determine which type of radiant heating pads are necessary to provide the best heat for that room.

No. There is empty space between the sun and earth, but radiant heat gets through that empty region.
Radiant heat transmits in the form of waves.
It may be converted into heat (or cause chemical reactions to occur), otherwise it remains radiant energy and escapes back into space. Note that much of what stays as heat is converted back into infra-red radiation and lost into space at night.

Good insulation is the biggest protection. The vacuum of space is an excellent insulator, the transfer of heat energy is primarily through contact and radiant heat.

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.

The abstract noun for the adjective radiant is radiance.The word radiant is also a concrete noun; a word for the point or object from which light or heat radiates; the point in space from which a meteor shower appears to emanate.
