    摘要： A radiant heater, in particular for heating a glass-ceramic hot plate, has an area bearing an electrical heating element, with this area being the surface of an insulator which comprises a mounting layer and/or a thermally insulating microporous insulation layer, and having a dish-shaped enclosure which forms an annulus surrounding the insulator. The radiant heater has the mounting layer and/or the enclosure and/or the microporous insulation layer comprising a highly porous, fiber-free inorganic material, for example vermiculite. A particularly preferred embodiment provides for a fiber-free radiant heater.
