Radiant Heating is a form of heat transfer. Radiant Heating Panels emit most of their heat via longwave infrared radiation as opposed to convection or conduction. The longwave radiation that is emitted from the Radiant Heating Panels travels through the air (without directly heating the air) to its surroundings of lower temperature (such as walls, floors, desks, and occupants) thus raising the temperature of these surroundings. A secondary effect of the longwave radiation being emitted from the Radiant Heating Panels is that the air is heated by being in contact with the warmer surfaces.
