ABSTRACT:
An improved PTC electric heating element assembly comprises a heating element of a ceramic material with positive temperature coefficient, two insulating elements with different thickness, and four metal sheets, which are arranged in a stack to firmly join together by a fastening means fixed on the bottom of a container. The opposite sides of the heating element are contacted by metal sheets having electrodes which are connected to electric wires to effectively conduct the heat produced to the container.
