The invention relates to water heating systems with forced circulation of coolant in the Autonomous si

Known water-steel boiler, comprising a housing, provided the furnace is made with double walls, bottom and cover with insulation, forming the volume of water supplied by a pipe to the water inlet and valve selection water pipe connection to the chimney frame for mounting the burner device and a heater installed in the furnace, the water heater is equipped with nozzles individually connected to the heating system and installed on the brackets, and the heater is made in the form of sections fastened together their opposite ends by means of transition pieces and placed their heat exchange surfaces with tilt angles 2-3oon the two sides. The heater is made in the form of sections fastened together their opposite ends by means of transient nozzle with the formation of a space between the heat exchange surfaces of the sections and offset relative to one another to opposite sides of the case for the formation of gas moves across sections with oppositely changing directions (see U.S. Pat. RF N 2113660, CL F 24 H 1/00).

The disadvantage of this boiler is the design complexity, the low the l, containing a furnace with a burner device located in the lower part of the boiler, the vertical beam heating pipes installed inside the outer tube, the nozzle forward and backward water expansion tank (see Domestic hot water fire tube boilers-type MMP - 1,0/8, MMP - 0,7/8, AGV -120, Moscow machine-building plant, 1995).

The disadvantage of this boiler is the high cost of heat production, the use of electric pumps serving the boiler and heating system.

The closest in technical essence and accepted by the authors for the prototype is a heating system comprising a hot water boiler supply and return lines of the heating system, circulating boiler feed pump with throttle valve, safety valve, thermostat (see the prospectus of the company OSBY OPEX Sweden, 1998).

Heating system with forced circulation of the coolant is as follows.

When starting the heating system includes a boiler 1, after heating boiler 1 over 60oC circulation pump 4. During startup of the boiler 1, thermostat 10 is mounted with the sleeve 11, the removable cover 12 and the spacer 13 is in the off state, the supply of cold water through the pipe 9 into the heating system is closed. All the water circulating pump is supplied through the bypass pipe 4 8 3 back line, bypassing the heating system. As the warm boiler 1 when reaching 80oC (temperature setting start operation of thermostat 10), part of the heated water begins to flow into the heating system through the feed line 2 via the pipe 9, is installed in the upper part of the cylindrical body 6, and the part continues to do 3 back line through the pipe 8, while maintaining the desired water temperature at the inlet to the boiler 1. With the full warm-up heating system, thermome the invention in comparison with the prototype and other known technical solution has the following advantages:
