The heat-conducting layer has at least one heat-conducting track that is arranged on the substrate, and the heat-conducting track is structured such that a multiplicity of track sections, separated from one another by insulating gaps, is formed. The heat-conducting track has at least one deflection section at which the heat-conducting track is deflected and which is arranged between a first and a second track section, wherein the first and the second track section have a smaller curvature in comparison with the deflection section. The heat-conducting track in the first track section or in the deflection section branches into at least two branch tracks separated from one another by one or more branch insulating gaps. The branch tracks meet up again in the second track section or in the deflection section.

Abstract: The invention relates to a control device (12) for an engine-independent heater (3) that heats a liquid heat transfer medium of a heat transfer medium circuit (1) especially for motor vehicles. Said control device (12) reduces a heater (3) capacity when an actual temperature gradient ((dT/dtIst) of the heat transfer medium is equal to or exceeds a temperature gradient threshold value ((dT/dt)Schwell). The control device (12) determines the temperature gradient threshold value ((dT/dt)Schwell) dynamically in accordance with a difference in temperature (??) between a target temperature (?Soll) of the heat transfer medium and an actual temperature (?Ist) of the heat transfer medium. The invention further relates to a heater (3), a heating system (1), and a method for controlling the inventive heater (3).
