Abstract
A heating system with PTC heating elements heats a medium that flows. In order to avoid unnecessary heating up of the PTC elements when the streaming fails, the required heat output that is to be generated by the PTC elements is compared to the electrical power actually consumed and, if a specified threshold value is under-run, the required heat output that was set is reduced accordingly.
