An apparatus for heating surfaces in the internal space of a motor vehicle comprises at least one heating element, having at least one heating conductor that forms an electrical heating circuit, and at least one carrier material, wherein the heating conductor has at least two HC terminal ends and the temperature acquisition element has at least two TA terminal ends. This apparatus for heating is characterized in that at least two of the HC and TA terminal ends are electrically connected to first HC terminal areas or first TA terminal areas of a printed circuit board and in that the printed circuit board has second HC terminal areas and second TA terminal areas, wherein the first HC terminal areas and the second HC terminal areas are at least in part connected to each other via first pcb traces and the first TA terminal areas and the second TA terminal areas via second pcb traces, wherein the first and the second pcb traces are part of the printed circuit board, and wherein the printed circuit board is arranged on, under or at the at least one carrier material.
