Abstract (en)
A device for controlling a hot water supply, which consists of a boiler (1) with a burner (3) for heating a heating medium, and a continuous-flow heat exchanger (9) which contains a service water pipe (13) for tap water. The continuous-flow heat exchanger being connected to the boiler (1) on the one hand via a supply pipe (5, 10) and on the other hand via a return pipe (7). The heating medium circuit having a circulation pump (8) as well as a regulating device for keeping the tap water at a predetermined temperature. The regulating device consists of a single temperature transmitter (16) which is connected to the tap pipe (13) near the point (15) where the latter leaves the continuous-flow heat exchanger. The temperature transmitter being connected to a control element (17) which detects the temperature drop per unit time and if a predetermined value is exceeded sets the burner and circulation pump in operation. The control element being also capable to registrate the relationship between the temperature change of the heating medium and that of the tap water in order to detect if tap water is drawn off or not.
