A device for detecting and signalising a leakage in a double-walled conduit system of a heat exchanger for heating fresh water by way of heat from waste water in the sanitary field as well as a heat exchanger including such a device. The device has an elastic element and a signalisation unit, wherein the elastic element is essentially liquid-tight and the signalisation unit is configured to generate an acoustic signal and the signalisation unit is activatable by way of a mechanical deformation of the elastic element.

Device for the detection and signalisation of a leakage and a heat exchanger

A heat exchanger for heating fresh water using heat from wastewater in a shower or bathtub. The heat exchanger has a drain pan, a heat exchanger unit that is arranged in the drain pan, and a distributing element for distributing draining wastewater over the heat exchanger unit. The heat exchanger unit has multiple tube portions that follow one another sequentially and are connected to one another by diverting portions. Each two horizontally running tube portions that follow one another and that are thus connected by a deflecting portion are arranged one over the other, and wastewater, which is dripping or flowing down, is sprinkled on or flows over the tube portions one after the other.
