The air feed chamber (3') through which the heat exchanger (6) fits is formed as a vertically orientated channel (3) limited by a heat insulation (8) arranged in the heating body enclosing housing (7). This channel on the outflow side has a flow pressure-dependent, automatically opening and closing stop (9). At the bottom on the inflow side is a regulatable fan (10). The heating body enclosing housing is formed as a flat, rectangular box (7'). In the heat insulation are at least two channels through which heat exchangers penetrate. The heat exchanger is formed as a tube with outer longitudinal ribs, the outer diameter of which corresponds to the inner diameter of the channel. The two end areas of the channel (3) are formed as funnels (12). |
