A heating device for a domestic appliance includes a planar carrier having a carrier surface. Thermally sprayed onto the carrier surface is a layer structure, and a first solder volume is applied to the layer structure. The solder volume is an ultrasonically soldered-on solder volume. The layer structure can hereby be a heating conductor layer.

The invention relates to a combination of an electrical heating element and a heat dissipater to be heated thereby; the heating element comprises a substrate, an insulating layer located on the substrate and a thick film conductor located on the insulating layer, wherein the second side of the metallic substrate is in contact with the heat dissipater, comprising a layer of metallic material on its face towards the heater and wherein the substrate is brazed to the heat dissipater and the surface of the heating element over which the thick film conductor extends, is substantially equal to the surface of the heat dissipater. The brazing leads to a permanent contact between the heating element and the heat dissipater, so that the possible tendency for warping as caused by the heating and cooling cycles will be withstood.

An infrared heater having a reflector body that includes a first and a second planar reflection section for arranging one infrared radiator in each case and a reflector opening opposite the reflection sections. In order to provide an infrared heater that allows for controlled emission of heat, the reflection sections extend in planes with respect to a first longitudinal axis, which planes are oriented so as to be inclined in relation to one another and which each extend at different inclinations in relation to an opening plane that is oriented in parallel with the first longitudinal axis and that is spanned by the reflector opening.

The present invention provides a heating apparatus for heating a load. The heating apparatus comprises a heater having a heating element for receiving electrical power and for converting the electrical power into heat to heat a heating surface of the heater. The heating apparatus also comprises a temperature sensor for sensing and outputting a measurement of the temperature of the heating element, a power actuator for providing the electrical power to the heating element of the heater, a power sensor for sensing and outputting a measurement of the power provided to the heating element by the power actuator, and control circuitry for controlling the power actuator to control the power delivered by the power actuator to the heating element. The control circuitry is configured to receive the temperature measurement from the temperature sensor, receive the power measurement from the power sensor, combine the temperature measurement and the power measurement, and control the power actuator in dependence upon the combined temperature measurement and power measurement. This ensures that the temperature of the heating surface is constant throughout a period when the load is applied.
