<p>Radiant heater has a surface carrying electric heating wire, this surface is a top surface of insulation body (3), which comprises bearing layer and/ or heat-insulating microporous insulation layer, and dish-shaped rim (2), which annularly surrounds insulation body (3). Bearing layer and/ or rim, and/ or microporous insulation layer contains a highly porous, fibre-free inorganic material, for example vermiculite. Particularly preferred configuration provides a fibre-free radiant heater.</p> |
