An example apparatus includes an interface to be electrically coupled between a heating element and a power supply, where the heating element associated with an external surface of a vehicle, and where the power supply is to provide power to the heating element. The interface includes a balanced current sensor to measure a differential between a first current of an electrical power line of the heating element and a second current of an electrical return line of the heating element, and a processor to compare the differential to at least one threshold to determine a condition of the heating element.
