Radiant Heating

According to Wikipedia,

Radiant heating is a technology utilized for the heating of both indoor and outdoor areas. Radiant heating consists of “radiant energy” being emitted from a heat source. Radiant heating heats a building through radiant heat, rather than other conventional methods including convection heating. The technology has existed since the Roman use of Hypocaust heating. The heat energy is emitted from a warm element (floor, wall, overhead panel) and warms people and other objects in rooms rather than directly heating the air. The internal air temperature for radiant heated buildings may be lower than for a conventionally heated building to achieve the same level of body comfort (when adjusted so the perceived temperature is actually the same).
