A system for an aircraft includes a heater comprising a resistive heating element and insulation surrounding the resistive heating element. A first current flows into the resistive heating element to provide heat and a second current flows out of the resistive heating element. The system further includes a leakage sensor configured to produce a leakage sensor signal representing a leakage current from the heater and a prediction processor configured to predict heater failure based on the leakage sensor signal.
