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).
