The implementation of the invention

The outdoor condensation hot water boiler consists of a thermally insulated housing 1, inside which a vertical thermally insulated hot water boiler 2 with a gas burner 3, a chimney 4 is installed, an additional heat exchanger 6 made of corrugated stainless steel pipe is installed in the smoke collector 5 of the boiler 2, while the inlet pipe of the heat exchanger 6 is connected with the return line 7 of the heating system 8 of the heating, the outlet pipe of the heat exchanger 6 is connected to the return pipe 9 of the boiler 2 and contains Atomic air vent 10, the straight pipe 11 of the boiler 2 is connected to the direct line 12 of the system with a return heating line 7 through an automatic thermostatic three-way valve 13, with each gas pipe 14 containing a flue gas turbulator 15, which is suspended from the pipe edges 14 by an arm 16 - which installs simultaneously necessary resistance to flue gases. A protective washer 17 is welded to the bracket 16, a condensate pipe 18 is placed at the base of the smoke collector 5.

The condensation boiler outdoor installation works as follows.

The building heating system 8 is filled with coolant, the air from the vertical boiler 2 is removed through a straight pipe 11, an automatic thermostatic three-way valve 13, a straight line 12 to an expansion tank (not shown in Fig.), The air from the heat exchanger 6 is vented to the atmosphere through an automatic air vent 10 .Opening the door of the thermally insulated building 1, a gas burner 3 is lit, flue gases rise upwards through the gas pipes 14 into the smoke collector 5 of the boiler 2 and are removed into the atmosphere by the chimney 4. ozhdenii flue gas of a gas pipe 14, turbulators 15 the flue gases impart rotational movement of the gases, which contributes to a better heat transfer of heat from the flue gas heat carrier, because of the low coolant temperature, an automatic three-way thermostatic valve 13 is closed, the circulation of the heating system of the building 8 is absent. Drops of condensate formed on the surface of the heat exchanger 6 fall down onto the grate of the gas pipes 14 and the protective washers 17 and are removed from the smoke collector 5 of the boiler 2 through the condensate drain pipe 18. Thus, condensate from the smoke collector 5 does not enter the gas pipes 14. After heating the coolant inside boiler 2, an automatic thermostatic three-way valve 13 opens and the coolant in a straight line 12 enters the heating system 8, cooled in the heating system 8, the coolant in the return line 7 of the heating system 8 enters exchanger 6, wherein the warmed, is sent to the heat exchanger outlet nozzle 6 to a return pipe 9 of the boiler 2. warmed up, in boiler-tube portion 2, by direct coolant conduit 11 via the automatic three-way thermostatic valve 13 is guided in a straight line 12 of the heating system. Flue gases in the smoke collector 5 constantly wash the surface of the heat exchanger 6 and are removed by the chimney 4 into the atmosphere. Since the temperature of the heat exchanger 6 is below the dew point on the surface of the heat exchanger 6, condensate droplets are constantly formed, which fall down onto the grate of the gas pipes 14 and protective washers 17 and are removed from the smoke collector 5 through the condensate pipe 18. Thus, the gas pipes 14 and all other elements Boilers 2, located below, do not fall under the influence of condensate, which allows them to be made from traditional materials without raising the cost and making condensing boilers for outdoor use available to the Russian buyer.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- reducing the cost of installation due to the manufacture of a boiler from traditional materials, with the exception of only the heat exchanger installed in the smoke box, which is made of stainless corrugated pipe;

- increase in efficiency up to 100%;

- cheaper heat production and lower cost of heating water.
