Beschreibung
Zusammenfassung:	The heater (1) receives cold water from a fresh water container and supplies the heated water to a filter device via a riser pipe. The heater is formed as a flexible loop (2), e.g. of plastics hose, containing a resistance heating element, e.g. a helical resistance wire. Each end of the heating element is connected to the inside surface of a conductive tube section (5) fitted into each end of the loop (2) and projecting from it. The tube section (5) adjacent the fresh water container is connected via a wire (7) to a membrane switch (6), while the other tube section (5) is connected via a second wire (10) to a safety switch.
