Abstract (en)
[origin: US2017086257A1] A heating device for heating water has a carrier to which at least one heating element is applied, the heating element having one or more heating conductors which are connected one behind the other. The heating device has a flat dielectric layer which substantially covers the heating conductors or the heating element. An electrically conductive connection area is in each case provided on both sides of the dielectric layer with the same coverage. At least one of the connection areas is connected to a controller for evaluating a leakage current as current flows through the dielectric layer, and the heating element is connected to measuring means for monitoring a heating conductor current through the heating element. Both the leakage current and the heating conductor current are monitored over time and faults can be identified if there are conspicuous changes.
