A thermal control for an electrical heating appliance comprises a switching mechanism arranged to be actuated by thermally responsive actuating means so to as to change the heating state of the vessel, and by further actuating means, which may comprise a mechanical, electrical or electronic actuator. The actuator may be controlled remotely of the appliance. The control may further include means for controlling additional functions of the appliance. The additional functions may be manually controlled independently from a heating state of the appliance. The means for controlling the additional functions may be integrated with the control, or may be added to the control during installation.
