Abstract: The invention provides a radiant heater comprising a radiative heating element (15, 16); a housing (1), the underside of which is recessed to receive the radiative heating element (15, 16), the radiative heating element being disposed beneath the housing (1) such that its upper half is wholly within the recess, and at least a portion of its lower half protrudes downwardly from the recess; the recess having a heat reflective surface (5a, 5b, 5c, 6a, 6b, 6c) for reflecting heat radiation from the radiative heating element (15,16) in a downwards direction; the housing (1) having means (9) enabling the attachment thereto of a reflective skirt (19) for focusing the radiation emitted from the radiative heating element (15,16).

Abstract: A radiant heater comprises first and second reflector portions (1, 2); first and second side reflector plates (3, 4); first and second end reflector plates (5, 6); first and second steel U-tubes (7, 8) received by the first and second portions (1, 2) respectively; end reflector plates (9, 11) for the reflector portion (1) and end reflector plates (10, 12) for the reflector portion (2), the ends of the tube (7) protruding through the plate (9) and the ends of the tube (8) protruding through the plate (10); first and second gas (or oil) burners and control units (13, 14) communicating with the ends of tubes (7, 8) respectively nearer a V-shaped channel; and first and second suction fan units (16, 17) communicating with the ends of tubes (7, 8) respectively which are further from the channel (15). In use of the heater, gas (or oil) is burnt at the burners and control units (13, 14), and hot air is sucked through the tubes (7, 8) by the suction fan units (16, 17).
