Abstract
A surface heater for a household appliance includes an electrically insulating insulation layer having a permittivity which changes as a function of temperature. At least one strip-shaped heat conductor is applied to the electrically insulating insulation layer, and at least one measuring electrode which is electrically insulated in relation to the at least one heat conductor is applied on a same side of the insulation layer as the heat conductor.
