Abstract
An immersion heating element comprises first and second heat conducting substrates defining top and bottom surfaces of the heating element. An electrically insulating layer is provided on one side of each substrate, and the two substrates are mounted together with the insulating layers facing each other and with a resistive heating track sandwiched between the insulating layers. This structure avoids the need for a thick protective insulating layer over the heating track.
