<p>The invention relates to heat-power engineering and can be used for hot-water heating and/ or a hot water supply to buildings and constructions. The inventive device comprises a body, a gas heat generator, first and second heat-exchangers and a condensate collector arranged in a cavity of said body. Each section comprises two shaped metallic sheets hermetically joined to each other, thereby forming winding channels for passing a hot liquid between the sheets. The condensate collector comprises air-cooled hollow condensation gutters having a V -shaped cross section and the bottoms thereof are oriented to a supporting surface of the body. Sleeves for passing the hot liquid between the sections of the heat-exchangers and a part of each sleeve for a liquid supply and/ or removal are formed with the aid of a profile of the corresponding shaped metallic sheet of the side section of said heat-exchanger which is also provided with orifices for passing the hot water. The hollow condensation gutters are arranged at angles to the surface of the body ranging from 3° to 45° and provided with extensions of side edges used for running off a condensate and having a length ranging from 1 to 3 mm.</p> |
