Zusammenfassung
(EN)

A method for starting operation of a device for providing a liquid additive, the device having at least one preheating element and at least one PTC heating element, includes: a) heating by the at least one preheating element; b) conducting heat from the at least one preheating element to the at least one PTC heating element such that a temperature of the at least one PTC heating element is raised; and c) heating by the at least one PTC heating element when the temperature of the PTC heating element has been raised.
