Abstract
A panel heater with at least one flat substrate and an electrically conductive coating is described. The electrically conductive coating extends at least over part of a substrate area and is electrically connected to at least two connecting electrodes provided for electrical connection to the two terminals of a voltage source, such that by applying a feed voltage, a heating current flows in a heating field, which is provided with one or a plurality of heating current paths formed into the conductive coating. The panel heater has one or more measurement current paths formed into the electrically conductive coating, which differ at least in sections from the heating current paths. The heating and measurement current paths are formed into the electrically conductive coating by coating-free separating regions. A method for operation and use of the panel heater is also described.
