necessary. In addition, the temperature sensor I Claim: in the domestic water inside the heat exchanger | appropriate, which causes a certain delay in the start f ' Arrangement in the case of hot water circulation. Speaking of the heating with domestic water withdrawal! ■■ brings with one in the shunt to the heating circuit 5 with it. - _; between the supply and return lines connected- In the main patent 1 266 944 there is an arrangement at ;; th heat exchanger for domestic water heating - a hot water circulation heating system with a heating system as well as a priority switching device connection to the heating circuit between forward and backward - J! device, which is designed as a thermostatic valve, flow line switched on heat exchanger for Ij which the flow line optionally shown to the auxiliary io domestic water heating. A priority switching device described in the main circuit or to be connected to the heating circuit, a heat sensor of the thermostat combines two functions Use water heater. But it also regulates the domestic hot water supply, the inlet 15 of which is at the same time thermostatically dimensioned the flow through the river is larger than the influence of the pre-heating circuit, by having a relatively high flow temperature and return temperature according to the patent and less at a high flow temperature 1 266 944 depending on the flow temperature or no water through the shunt to the return with a connected heating circuit allows part of the flow line to pass through. .
Running water over the shunt to the return 20 The invention is based on the task of maintaining these two functions, while maintaining these two functions, the priority is given, characterized by improving the switching device and to Vereindaß the heat sensor (14) of the thermostatic valve, in particular to replace the electromotive switch (12) within a through-connection from the flow water when the used water is drawn through the flowing chamber (7) of a pipe loop (16) 25, a thermostatic switch,
the cold water supply line (15) of the service water To solve this problem is surrounded by the Erfinsererhitzers (9). Proposal proposed that the heat sensor of the thermostatic valve within a chamber through which the flow water flows from a pipe loop of the ■ 30 cold water supply line of the domestic water heater \ ■ is surrounded. An embodiment of the invention is in the fol- The invention relates to an arrangement with reference to a schematic Ab- at a. Hot water circulation heating with an in the education explained in more detail. Shunt to the heating circuit between flow and 35 With 1, the heat exchanger is a flow-return Line switched on heat exchanger for heater called, the heat through a gas domestic water heating and a priority re-burner 2 is fed. On the heat exchange switchgear, which is designed as a thermostatic valve 1 is through a flow line 3 and a det is the supply line optionally to the Ne return line 4, a radiator 5 containing Heizbenschluß or to be connected to the heating circuit. A circulation pump 6 is in the equips, with a heat sensor of the thermostatic valve return line 4 switched on. The flow line 3 in addition to the flow temperature, there is also an inlet connection 7 'with a priority-order cold water temperature connected in the utility water supply switching device 7. Is exposed at an outlet, the influence of which is dimensioned larger trim 7 ″ is the one leading to the radiators 5 is connected as the influence of the flow or return temperature 45 branch 3 'of the flow line. A white and according to patent 1,266,944, the priority changeover flow temperature according to the front connection piece 8 ' When the heating circuit is connected, a device 7 is used to connect a return part of the flow water via the shunt to the line 4 leading connecting line 8, into the one Return line from the switching device through heat exchanger 9 is switched on. The warmth will. 5 ° exchanger 9 contains a coil 9 'in which By the German patent specification 1 270 768 it is used water is heated. known, in a hot water circulation heating system with between the connecting pieces 7 ', 7 "is in the one in the bypass to the heating circuit between priority switching device 7 a valve seat 10 forward and return line switched on heat exchange Service water heating and terminates with a connection piece 8 ', is located opposite the valve seat 10 designed as a thermostatic valve. Between the valve seats 10 and 11 there is a switching device that optionally connects the flow line with a valve closure body 12 and connects to the bypass or to the heating circuit - out a valve stem 13. The valve stem 13 is allowed to close, the temperature sensor of the thermometer connected to a heat sensor 14, which is located in the inmostatic valve within the heat exchanger in the priority switching device 7 of the temperature so that it is about two thirds into the temperature des from the flow line 3 into the nozzle T Brauc hwasser immersed and stands with the remaining part of the entering water. The cold water inflow is acted upon by the flow water. As a result, from a line 15 to the pipe coil 9 'of the Ge, the influence of the service water temperature is achieved via a temperature which is larger than that of the flow water temperature 65 priority switching device 7. However, in this arrangement temperature pipe loop 16, which closely surrounds the heat sensor J4, sensor and switching valve are arranged separately, and 17 is a nozzle for water ducks an electromotive switch of the valve is referred to.
