Arrangement for the provision of hot water for continuous-flow storage water heaters heated by gas wall appliances

摘要

The arrangement serves to improve the provision of hot water in domestic hot-water supply systems. The object is to provide an arrangement which ensures immediate provision of hot water with fully heated-up water at the drawing point on opening the latter and this eliminates the starting losses which could not be prevented hitherto. The object is achieved in that a thimble joint (ring connection) is provided, including a water switch with venturi nozzle which recognises flows which occur by evaluating the pressure conditions in the venturi nozzle and this sets the gas wall appliance in operation. By means of a control device and a timer, in cooperation with a temperature sensor which evaluates the temperature in a special connecting conduit of this thimble joint, a circulation pump in a circulation conduit is set in operation and thus in this thimble joint, which also comprises the drawing points, the hot-water temperature is constantly maintained at a preset temperature level.
