<p>The heater (1) has a radiation pipe accommodated in a reflector housing (2) and supplied with heat energy by a burner (6). The housing has a side wall extending along a side of the pipe, where infrared-radiation provided by the pipe is reflected at the side wall. The side wall has a suction opening (20a) in an area of a longitudinal edge that extends along the pipe. The opening stays in flow connection with an air supply opening (8) of the burner over an air suction channel, where air heated in an inner side of the housing is sucked by the suction opening and supplied to the burner.</p> |
