Die Niederdnickseite des Wasserschalters 25 steht über eine Leitung 28 mit der Rücklaufleitung 3 vor der Pumpe 4 bei 27 in Verbindung. Die Hochdruckseite des Wasserschalters steht eb&nso über eine Leitung 29 bei 30 über dem hinter dem Dreiwegeventil M liegenden Zweig 21 der Vorlaufleitung 7 in Verbindung.The low-thickness side of the water switch 25 protrudes via a line 28 to the return line 3 the pump 4 at 27 in connection. The high pressure side of the water switch is eb & nso over a line 29 at 30 above the branch 21 of the flow line 7 located behind the three-way valve M in FIG Link.
Die Steuerdruckleitungen, die dünne Röhrchen sind, lassen sich mühelos verlegen.The control pressure lines, which are thin tubes, can be laid effortlessly.
Im Vorlaufzweig 21 und im Rücklaufzweig 31 der Radiatoren 8 sind Wartungshähne 32 und 33 eingebaut. In the flow branch 21 and in the return branch 31 of the Service taps 32 and 33 are installed in radiators 8.

Wenn die vorgegebene Temperatur gründe, bei einem gasbeheizten Durchlauferhitzer 55 erreicht ist, schaltet der Thermostat 24 die Beheizung nach dem Hauptpatrnt die Staudruck- und die vorübergehend ab.The main patent 1679 447 relates to a control device for the gas supply in the case of gas-heated water heater 10 being supplied via a branch II of the flow line 7. Instantaneous water heaters, which serve as a heat source for a The utility water heater 10 is used with the domestic hot water circulation heating system, in which a water line 12 is connected and is short-circuited under the heating circuit, from a switching valve 30 pressure of the same. It contains a boiler 13, which is surrounded by a controlled connection line between the supply and spacing of a second boiler 14, a return line is provided and in which there is a flow pressure in the short-circuited part of the heater with the intermediate space 15 between the boilers 13, 14 Flow line 11 in connection. The circuit responsive water switch is provided, flowing heating water gives its heat to the service water in the boiler 13 when the connection 35 is closed or throttled and the gas supply throttle .lt flows through the return line 3 to renewed recovery back to heater 1. The hot Ge-Heizbetriebes with throttled gas supply and waste water is operated via a line 16 with correspondingly reduced power. The temperature of the boiler water is monitored by can, while in the event of a short circuit in the heating circuit, a thermostat 17 monitors it. This can be set on the connecting line either during a heating period on a switch 18 attached to a jacket 19 or when water is being consumed. When the specified temperature has reached the full heating output of the device, the thermostat 17 is set via a relay Boiler 13 off.
Venturi nozzle is arranged, which for actuation If the resistance of the heating of the water switch is grooved for actuation, the pressure difference is so 6 , oß that it testifies to the operation of the heater. required amount of water can not flow through, with such an arrangement a relatively strong then is required in a known manner between the flow in the Hetekreis, by means of 50 flow branch 21 and the return line 3 one at the Venturi nozzle one for actuating the water 22 adjustable short-circuit line 23 provided,
The temperature of the switch via the flow branch 11 is sure to generate a sufficient pressure difference. . The present invention has the task of thermostat 24. When the predetermined temperature is reached in a gas-fired water heater 55, the thermostat 24 switches off the heating after the main valve, the dynamic pressure and temporarily off.
