Radiant heating is a technology for heating 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. Underfloor radiant heating has long been widespread in China and Korea. 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).

Tubing is attached to wire mesh or fixtures to hold them in place until the concrete floor is poured. The tubing or elements are embedded in the concrete anywhere from the bottom of the slab to within two inches of the surface, depending on the design and installation technique.
