Summary:water heating, applicable for hot-water supply of cottages, greenhouses, habitable settlements. SUBSTANCE: boiler has a body with an exhaust port for flue gases, positioned in its lower part is a radiation zone made of an internal cylinder with a burner provided with fuel and air inlet connections, and an external cylinder with heated water inlet and outlet connections. The cylinders are installed concentrically and form an interwall annular gap for flow of heated water, a tubular heat exchanger made in the form of a tube bundle is installed in the upper part of the body, nozzles, drip pan, waterlocks and a condensate tank with an entrainment separator. Heated water is fed to the upper part of the heat exchanger tube bundle with a subsequent discharge of it from its lower part and afterheating in the radiation zone, condensate is returned through the waterlocks installed at the same height with the tube bundle. EFFECT: enhanced efficiency and reduced overall dimensions and mass of the heat exchange surfaces prevented pollution of heated water by combustion products. 1 dwg
