A heating system for heating air, especially for heating the interior of a motor vehicle, with a first heater (), a second heater (), and a flow path between the first heater () and the second heater (), there being at least one auxiliary fan () with which a flow in the direction from the second heater () to the first heater () can be produced and a process for influencing the air flows in the heating system are designed to counteract overpressurization. Furthermore, an air heater and a process for detecting backflowing hot air through an air heater use a temperature sensor in an inlet area of the heater for that purpose.
