radiant energy: energy coming to earth from the sun
radiant energy: also called electromagnetic energy, made up of two fields (electrical and magnetic), existing in a range of wavelengths that extends from radio waves that many be thousands of meters long to gamma rays with wavelengths as short as a million-millionth (10^-12) of a meter

radiant heat: {i} heat transmitted by radiation
radiant heating: heating a building by radiation from panels containing hot water or electrical heaters
radiant heating: Method of heating whereby much of the heat transfer is accomplished by radiation through space from warm building surfaces such as floors, walls or ceilings
radiant heating: A method of heating rooms which consists of coils of electrically-heated wires or heated water pipes, embedded in the floor, wall or ceiling of a room
radiant heating: A method of heating, usually consisting of a forced hot water system with pipes placed in the floor, wall, or ceiling Also electrically heated panels
radiant heating: A method of heating, usually consisting of a forced hot water system with pipes placed in the floor, wall, or ceiling; or with electrically heated panels
radiant heating: Heating system in which heat is transmitted by radiation from a heated surface. Radiant heating systems usually employ either electric-resistance wiring or hot-water heating pipes, which may embedded in the floor, ceiling, or walls. Panel heating is a form of radiant heating characterized by very large surfaces (typically an entire ceiling or floor) containing electrical conductors, hot-water pipes, or hot-air ducts. With many such systems there is no visible heating equipment in the room
