ABSTRACT:
A modular infrared space heating device includes an enclosure having an air inlet and an air exhaust. A plurality of open-ended ferrous metal conduits are positioned in the enclosure between the air exhaust and a plurality of infrared lamps. The conduits are supported at only one end on a ferrous metal sheet. Refractive lens means comprising a glass plate having a plurality of convex focussing surfaces equal in number to the conduits is provided between the lamps and the conduits and arranged so that each convex surface focusses infrared radiation from the lamps on a different one of the conduits. A fan is provided in the enclosure for circulating air through the enclosure from the air inlet, over the lamps, through and around the conduits and out the air exhaust.
