A radiant heater includes at least one heating tube element comprising a heating tube which is transparent or semi-transparent to infrared radiation, and carbon fibers arranged within the heating tube. The carbon fibers form an infrared heating coil comprising a carbon string. The infrared heating coil is dimensionally stable. At least one infrared reflector comprises a focusing curvature which comprises a focus area. The at least one infrared reflector is adapted to the infrared spectrum of the at least one heating tube element. The at least one heating tube element is arranged in the focus area of the curvature A housing comprises a border side structure, a rear side structure, and at least one front face which is open, transparent or semi-transparent for infrared radiation. The border side structure and the rear side structure are arranged to surround the front face so as to shield from infrared radiation. |
