The heating boiler with the selection of hot water, contains an inner casing 1 (Fig.1-3), which is a welded box-shaped structure, closed on the outside with facing panels. Inside the body 1 (Figs. 1-3) of the boiler there is a water jacket 2 (Figs. 1, 2), framing the furnace and flue spaces. A steel heat exchanger 3 (Fig. 1, 2) is installed in the internal volume of the boiler, forming a closed loop of the heat-transfer medium with the cavity of the water jacket 2 (Fig. 1, 2). On the front side of the housing 1 (Figs. 1-3) of the boiler, there is a loading door 4 (Figs. 1-4), which serves for loading solid fuel, which is equipped with a thermal bridge 5 (Fig. 4), made in the form of thermal insulation. The thermal bridge 5 (Fig. 4) serves to ensure that heat from the furnace space is not transferred to the outer walls of the loading door 4 (Figs. 1-4). On the front side of the housing 1 (Figs. 1-3) of the boiler under the loading door 4 (Figs. 1-4) there is a shurovoi door 6 (Figs. 1, 2), intended for kindling, as well as for extracting the focal residue. Below the shuttle door 6 (FIGS. 1, 2) there is a secondary air gate 7 (FIGS. 1, 2), made in the form of a blower flap containing two plates in which vertical slots are made. When the plates move horizontally, the cross section of the slit changes and the amount of air entering under the grates 8 (FIG. 1) is regulated and thereby the intensity of combustion is regulated. Inside the lower part of the housing 1 (Figs. 1-3) there are grates 8 (Fig. 1) and an ash pan 9 (Fig. 1), which serves to collect ash. Grids 8 (Fig. 1) serve for the passage of air and separate the blower chamber 10 (Figs. 1-3) and the combustion chamber 11 (Figs. 1, 2, 4). The combustion chamber 11 (Figs. 1, 2, 4) is laterally and laterally limited by water-cooled sections of the heat exchanger 3 (Fig. 1), and is closed in front by the front sheet of the gas burner device (GGU), on which the collector 12 (Fig. 3) of the main burners is fixed 13 (FIGS. 2, 3) with nozzles and a bracket for the pilot burner 14 (FIG. 2) is installed. The main burner 13 (Fig.2, 3) is made of heat-resistant stainless steel and placed evenly under the heat exchanger 3 (Fig.1, 2), creating a uniform thermal field in the combustion chamber of the combustion chamber 11 (Fig.1, 2, 4), which eliminates the formation of local zones of overheating of the heat exchanger 3 (figure 1, 2) and its destruction.

Before putting the boiler into operation, it is necessary to fill the system with water until it appears from the overflow tank of the expansion tank (not shown in the drawings), then open the secondary air gate 7, open the tap on the return line of the heating system (if any) and check for draft.

When the heating boiler is operated with the selection of solid fuel hot water:

- it is necessary to melt the boiler with dry wood, loading the combustion chamber 11 to half its height and making sure that hot coals cover the entire grate, after coal is ignited, gradually load coal;

- loading fuel to produce in small portions, quickly, without leaving the loading door 4 open for a long time, in order to prevent a large amount of cold air from breaking into the combustion chamber 11;

- load fuel in such a way that the combustion level is not higher than the edge of the boot door 4;

- Download the entire volume to complete in about an hour;

- after the coal has flared up well, put the secondary air gate 7 in a position that ensures optimal combustion of fuel;

- to clean the grate 8 at least twice a day.

- not to allow a large accumulation of ash in the furnace, ash ash 9 should be cleaned twice a day;

- when slag accumulates in the furnace chamber 11, it is necessary to quickly select it, leave all unburned coal (heat) in the furnace, and then make another loading of fuel.

When operating a heating boiler with the selection of hot water using natural gas, it is necessary:

- ventilate the room in which the boiler is installed for 10-15 minutes;

- check whether the gas valve is closed directly on the gas pipeline in front of the safety automatics;

- check for draft in the chimney;

- install the control stick RTV automation unit "off";

- open the gas valve (not shown) of the gas supply to the safety automatics with a gas burner device;

- ignite the ignition burner 14 and the main burners 13 of the gas burner device (GGU) through the inspection window 35 with a paper band in the “ignition” position and hold it pressed for at least 30 seconds after igniting the gas on the ignition burner 14;

- after ignition of the ignition burner 14, remove the paper tow and extinguish it. Turn the control knob of the RTV water temperature controller of the safety and control unit 32 to the “Off” position.

- turn the control knob of the water temperature regulator of the safety unit and control 32 to any desired temperature for heating the water in the boiler and check the gas performance on the main burners 13 visually through the inspection window 35. After the combustion chamber 11 has melted, the heat in the pipes flows up and heats up water jacket 2, which has a developed convective surface. Heated water enters through the outlet pipe 23 into the supply pipe 24 of the heating line, heats the batteries and the heating pipes of the room. Then, after heat is transferred through the batteries and heating pipes to the rooms, the chilled water through the pipe 22 of the return line of the heating system is returned to the boiler. Thus, a closed cycle of the water circuit in the supply pipes 24 of the heating line to the pipelines of the return line of the heating system. The gate of the secondary air 7 provides control of the amount of air supplied under the grid-irons 8. When working on gas, the turbulators 18, the vertical component of the velocity of the exhaust gases in the pipelines is laid out on the horizontal component. This allows you to more effectively remove heat from the flue gases. Pure water through a pipeline and through separate nozzles enters a water heater (boiler) 19, located in the upper part of the internal volume of the boiler, is heated from a water jacket 2, heated to a temperature of less than 93 degrees and supplied to household needs. Upon reaching the set boiler water temperature, the automatics shuts off the gas supply to the gas burner device (GGU) and turns it on again when the temperature drops to a value determined taking into account the hysteresis zone in the automation, which should not exceed 10 degrees C.
