Abstract: A heating device comprises a circulation chamber with inlet and outlet openings for a heat carrier, a heating assembly connected to the circulation chamber in a heat-conducting manner for heating the heat carrier in the circulation chamber, a connection chamber with a control unit arranged therein and comprising a printed circuit board for controlling the PTC heating assembly, a partition wall between the circulation chamber and the connection chamber, and a hold-down device arranged on the side of the control unit facing away from the partition wall which interacts with the control unit. For an improved protection of the electrical heating device the hold-down device incorporates measures for collecting moisture, which are configured such that condensed moisture is kept away from the control unit, at least in certain areas.
