摘要
A device for switching off bare-wire heating elements (10) arranged in a water chamber (6) of a continuous-flow heater is intended for switching off the heating elements (10) in the event of air bubbles occurring in the water. For this, in each case one flow meter (8, 17) is arranged both in the cold-water inlet (2) and in the hot-water outlet (3). A control circuit (11) compares the measured values of the two flow meters (8, 17) and switches off the heating elements (10) in the event of a difference occurring. IMAGE
