Abstract
The invention relates to a heating module for a supplemental electric heating device for heating an airflow, comprising at least one heat-conductive bar against which at least one electric resistor is arranged. The heat-conductive bar is partially electrically insulated by an insulating coating in order to prevent potential short-circuits and to ensure proper operation and optimal safety when heating the passenger compartment of a vehicle.
