Abstract

The invention concerns a heating appliance which is protected against overheating in that the temperature increase during operation of the appliance is monitored. If the temperature increases too rapidly, the heating operation is stopped. According to the invention, temperature increase values are determined in a close chronological succession and/or a mean value is calculated in order to compensate signal noise from the temperature sensor.
