The device is to avoid virtually completely the heat losses based on heat radiation and, at the same time, is to conceal the unattractive reflector layer (1) which has a metallic lustre. This is achieved in that, at a distance (a) from the carrier plate (1a) with the reflector layer (1) and between said layer and the radiator, there is provided a further carrier plate (6) with a second reflector layer (7) directed towards the first-mentioned reflector layer (1). <IMAGE>
