<p>The hot air channel (20) is flowed through by hot air produced by the air heating unit (10) and is limited at least partly by ceramic heat radiation bodies, which are heated by the hot air and have heating surfaces which radiate into the room. At the outlet-side end of each hot air channel or branch a suction blower (30) is fitted. Each hot air channel or branch has one or more series-connected meander-form sections for formation of larger heating surfaces. The air heating unit has a heat radiator, eg. a gas heat radiator with electrical ignition together with a number of air heat exchanger bodies, eg. of ceramic material or cast iron, which are heated by the heat radiator, and via which the aspirated air reaches the at least one hot air channel.</p> |
