Abstract

The invention relates to a method for heating a feeding device (1) for reducing agent. Said feeding device comprises a recirculation valve (20) which is open when an opening current is supplied to the recirculation valve (20) and which operates as a heating element in the closed state when a heating current that is smaller than the opening current is supplied to the recirculation valve (20). The recirculation valve is preferably in heat-conducting contact with a metal base plate (6) of the feeding device (1).
