The invention relates to a system for heating dwelling and store stock. A gas double-pressure conic boiler with double liquid jackets consists of bases, there the vessel of the lower heat exchanger is placed, this consists of the inner liquid jacket formed by two conic and circular surfaces and a ring one and outer liquid jacket formed by two conic and ring surfaces installed in such way that between the conic surfaces there is a circular gas channel, areas of cross sections of that one are same in whole length. In the lower and the upper sections the volumes of the inner and the outer liquid jackets are connected to each other by channels. In the upper part of the outer liquid jacket an outlet branch pipe is installed. At above to the vessel of the lower heat exchanger a vessel of the upper heat exchanger is installed, this is of same arrangement, though turned by 180°. Through the openings in the circular surfaces the volumes of the lower conical heat exchanger are connected to the volumes of the upper conic heat exchanger by a pipeline. At above on the upper conical heat exchanger a deflector is installed, and a tap for air discharge. At beneath on the lower conical heat exchanger between the inner and the outer liquid jackets a circular gas burner is installed. The surfaces of the lower conic heat exchanger and the upper conic heat exchanger are protected with heat-insulation case. The efficiency of heat transfer is increased, and thus coefficient of performance is upgraded. |
