The invention relates to heat engineering and can be used in heating boilers and domestic water heaters.The closest analogue of the claimed izobretiny flue, water tanks heating system and hot water having adjacent surfaces, the node lowering the pressure, the inlet of which is connected to the main water pipeline and surge tank.The disadvantage of this technical solution is the low efficiency of heat exchange.Objective of the claimed invention is to improve the safety, reliability and efficiency through the intensification of the process of heat exchange.This object is achieved in that the boiler contains the combustion chamber, a vertical flue, water tanks heating system and hot water having adjacent surfaces, the node lowering the pressure, the inlet of which is connected to the main water pipeline and surge tank forming part of the site low pressure, between the main water supply and the hot water tank is the second node of lowering the pressure in the tank heating system has a vertical row of tubes, inside which are the products of combustion of fuel (e.g. gas), while the boiler contains mounted in staggered horizontal rows of tubes, washed by the products of combustion, the area inside which soondae the aqueous tank hot water system, in the case of which a valve which is connected with the main water supply, pivotally associated lever, which is fixed to the cover and the float, which interacts with the valve, and the circuit of the heating system may include a pump installed on the outlet of the boiler, for the selection of the hot water heating system.The drawing shows the design of the universal heating boiler.Universal heating boiler includes a burner 1, the combustion chamber 2, a horizontal tube 3, a vertical pipe 4, hot water tank 5, the tank heating system 6, a pump 7, the surge tank 8, the first and second nodes decompression 10, a storage tank 11, the valve for the cold water supply 12, the float 13, the lever 14, the rubber cover 15 and the vertical duct 16.The boiler operates as follows.Tank heating system 6 is installed vertical pipe 4. Through which pass the products of combustion (e.g. gas). On the outside of the pipe is washed by the water heating system. Inside the boiler to the hot water tank 5 water is from 60 to 250 litres depending on the type of the boiler at a temperature of 80-90oC. When the pressure in the water main to zero is Italy, automatically resumes heated water. When reaching the set temperature, the burner 1 of the boiler automatically shuts off going to the standby mode.The water in the tank 6 of the heating system has a higher temperature, because the heat is produced directly from combustion products of fuel (e.g. gas) through the walls of the combustion chamber 2, 3 horizontal and 4 vertical tubes. The water in the hot water tank 5 is heated through connecting with tank heating system 6 heating surface.The surge tank 8 with the first node low pressure 9 is used for automatic feeding of the heating system.To do this on the side surface of the housing of the surge tank 8 is installed valve 12. The valve communicates with the main cold water pipes. Through this valve, there is a constant feeding of the heating system and hot water.When water evaporates from the system the water level in the surge tank 8 is reduced. The float 13 is lowered and the lever 14, pivotally connected to the housing tank, removes the rubber cover 15 with the hole of the valve 12. Water flows into the surge tank 8. As soon as the water level in the tank reaches the set UB is way in the heating system is maintained at a constant water level.Same is true for the second node low pressure 10.The second node low pressure 10 combined with the storage tank 11. On the side wall of the housing of the storage tank are installed valve 12 and the lever 14. The valve is a tube with a truncated conical tip chamber connected with the main water supply. The hole in the tip is determined by the hot water consumption and the volume of the storage tank. If the tank is large, when the same hot water flow opening in the valve is selected smaller diameter and Vice versa. At the same time accumulating tank 11 performs the function of the surge tank. In the case of thermal expansion of water when heated in the tank hot water surplus water rise and can be discharged into the atmosphere. For this purpose there is a bypass pipe installed slightly above the level of accumulating water, which is determined by the position of the float 13.The lever 14 is rigidly mounted rubber plug 15 and the float 13.Using the first node to the low pressure 9 is a continual flow path of the heating system.There is no need to increase the size of the surge tank 9, because the water level to which the contour of the heating system boiler tank heating system 6 is directly connected with the surge tank 8. In this case, if necessary in connecting the pump 7 for lifting water in high-rise buildings should be installed on the hot water at the outlet port of the boiler. This leads to the fact that the pressure in the boiler increases and remains constant. It is determined only by the pressure of the water in the circuit feeding cold water, i.e., the installation height of the surge tank 8.Thus, expansion 8 and 11 cumulative tanks are installed above the point where you have installed the faucet hot water. They can be installed under the attic and the inputs of the nodes decrease 9,10 are connected to one gate from the main system cold water municipal water supply. When this discharge into the atmosphere can also be made through a single pipeline.When the accumulation of water in the tank, the float rises and the lever 14 rubber cap 15 closes the valve hole 12.The water level in the storage tank 11 is maintained constant until you open the hot water tap. As the flow rate of the hot water tank hot water 5 boiler is refilled with cold water from the storage tank 11. Until you use a supply of water in the tank hot water 5 boiler EA water in the storage tank from a water main, the filling of the tank depends on the diameter of the hole of the valve 12. 1. Universal heating boiler containing a combustion chamber, a vertical flue, water tanks heating system and hot water having adjacent surfaces, the node lowering the pressure, the inlet of which is connected to the main water line, and the surge tank, wherein the surge tank is an integral part of the first mentioned pressure reduction between the main water supply and the hot water tank is the second node of lowering the pressure in the tank heating system has a vertical row of tubes, inside which are the products of combustion of fuel (e.g. gas), while the boiler contains mounted in staggered horizontal rows of tubes, washed by the products of combustion, the interior of which communicates with the tank heating system.2. The boiler under item 1, characterized in that the second node pressure reduction is made in the form of the storage tank hot water systems, which body has a valve which is connected with the main water supply, pivotally associated lever, which is fixed to the cover and poplaw what I contains the pump, mounted on the pipe of the boiler for the selection of the hot water heating system.
