Warmwater heat-exchanger consists of a combustion chamber (1), which consists of an inner cover of the cooling-preheating degree (2) and of an inner cover of a water chamber (3). In the cooling-preheating degree (2) is placed an cooling exchanger (6) and in the combustion chamber (1) is placed a first heating exchanger (4), whose output is led to the input of a second heating exchanger (5). The output of the second heating exchanger (5) is connected to the input of a cooling exchanger (6). |
