Abstract
An immersion heater has a support plate on which there is provided an electrical heating element in the form of a printed circuit conductive track. The element is provided with a portion which allows it to be clamped in direct relation to a control unit in order to provide direct electrical, thermal, and mechanical connection to that unit. This allows the control unit to operate in the same manner as a control unit connected to a conventional immersion heater. A water heating vessel using the immersion heater mounted to a control unit through an aperture in the base of the vessel is also disclosed.
