A heating element 3 has portions 6 which may be contacted by spring terminals 7 of an electricity supply inlet connector 4. The element may take the form of a planar element for a water heating device such as a kettle. The element may comprise a thick film heating element with a resistive layer or track formed on a substrate and with terminal pads exposed through the outermost insulating layer. The kettle may be a cordless appliance having a connector system which allows the appliance to be seated on its base irrespective of its rotational orientation. A heating element overtemperature control 24 or a steam sensor control 22 may be provided on the appliance. The invention may be used in other devices such as irons, toasters and ovens.
