ABSTRACT:
The invention relates to a heating element with at least one electrical resistance, wherein between a surface for heating and the electrical resistance is situated a dielectric, onto which dielectric connects an ammeter for detecting a leakage current. In addition, the invention comprises a liquid container provided with such a heating element. The invention also relates to a method for detecting a temperature change in a heating element formed by an electrical resistance by measuring a leakage current discharged by a dielectric connected to the heating element.
