Abstract (en)
[origin: EP0529299A1] The heater has a tank (6) with a water bath. Situated in this water bath is a heating coil (9) for heating water. The water bath in the tank is heated by the hot gases emerging from the combustion chamber (4) through the smoke gas outlet (5). Accordingly, the heating coil (9) and consequently the heating water in the water bath are heated. For the heating water, there is provided in the combustion chamber (4) a lens-shaped heat exchanger (17) which is flowed around by the smoke gas. A second, bowl-shaped heat exchanger (12) is arranged directly outside the combustion-chamber wall (16). At the same time, the combustion-chamber wall (16) forms the inner wall of the bowl-shaped second heat exchanger (12). The heating water flows through this first heat exchanger (17) and second heat exchanger (12) in two parallel flows, to emerge at the forward-run connection (14). By means of this arrangement, in particular of the lens-shaped heat exchanger, high heating-water forward-run temperatures can be achieved in spite of relatively low set heater temperature values, with which an optimum degree of efficiency is achieved. <IMAGE>
