An ultra-thin heating device includes an upper heating pad, a lower heating pad, at least one electric heating piece and a power supply. The electric heating piece is installed at a preset position between the upper heating pad and the lower heating pad. The electrothermal sheet is electrically connected with the power supply. The upper heating pad and the lower heating pad are made of soft material. When a food needs to be heated, the food is placed on the preset position of the upper heating pad corresponding to the at least one electrothermal sheet, and the power supply provides electric power to the at least one electrothermal sheet to heat the food. Because the upper heating pad and the lower heating pad are made of soft material, when not in use, the ultra-thin heating device can be folded or rolled up for storage.

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.
