Abstract

The radiant heating element comprises a sensor (21) which is formed straight and without ties. The sensor has section which runs over the heating zone (17) which in turn has a straight electric conductor. The heating element is arranged on a metal plate which has two connections for the sensor. The sensor is electrically insulated against the metal plate in at least one end region (22). An Independent claim is also included for a hub with electric heating elements.
