A system for an aircraft includes a heater (14) comprising a resistive heating element (22) and insulation (24) surrounding the resistive heating element (22). A first current (I1) flows into the resistive heating element (22) to provide heat and a second current (I2) flows out of the resistive heating element (22). The system further includes a leakage sensor (17C) configured to produce a leakage sensor signal (VL) representing a leakage current (IL) from the heater (14) and a prediction processor (20) configured to predict heater failure based on the leakage sensor signal (VL).
