ABSTRACT:
An underfloor heating system includes structure defining vertically adjacent upper and lower communicating cavities beneath the floor of a room to be heated. A noncombustible heat source is provided in the lower cavity. Barriers are arranged in both cavities to define communicating compartments therein. The heat source includes an arrangement for directing hot air produced thereby through the compartments in the lower cavity. The cavities communicate such that hot air passes first through the lower cavity compartments, then through the upper cavity compartments, and back to the heat source.
