ABSTRACT:
The invention describes an electrical heating facility for the heating of liquid, in particular of washing liquid of a window washing facility, in a motor vehicle, comprising a metallic housing (2) with a first end (3) for immersion in the liquid to be heated and a second end (4) with an electrical connection terminal (5); at least one heating element (11) that is arranged in the housing (2); and at least one metallic heat conducting element (20) for conducting heat away from the housing (2). The invention provides the heat conducting element (2) as a stamped-out heat conducting plate comprising a slit that is used to slide it onto the housing (2). Moreover, the invention describes a liquid container with a heating facility, in which a heat contact surface of the heat conducting element (20) of the heating facility (1) rests against an intake fitting (31) that protrudes into the container.
