A heating device for a cooking point in a hob has three independent and separate long heating elements which are arranged on a support of the heating device along concentric circles. The support has a central region around the center point, an outer region adjoining an outer edge, and an intermediate region between the central region and outer region. A rod-type thermostat engages over the heating device for the purpose of temperature detection. The first and the third heating element are connected to an energy supply over the rod-type thermostat. A second heating element is connected to an energy supply without interconnection of the rod-type thermostat, wherein the second heating element is arranged on the support in the central region, in the intermediate region and in the outer region.
