Stationary infrared radiator

Abstract

A stationary infrared radiator which is to be operated in a decentralized manner for heating buildings, including a reflector and at least two different components which emit IR radiation for heating, the reflector having a longitudinal axis (L) and a transverse axis (Q), which runs at right angles to the longitudinal axis (L) and parallel to the reflector, and a reflector surface. The first component is designed as a bright radiator or as a dark radiator and has a connection for supplying fuel gas. The second component is designed as an electrical resistance heater having at least one heating element. The aim is to control the temperature more precisely and simultaneously to produce the infrared radiator more simply. The first component and the second component are respectively disposed offset from one another in a direction of the transverse axis (Q) and in a direction at right angles to both axes (L, Q) in front of the reflector surface.
