Abstract

A heating device, e.g. a heating element for a kettle, comprises a heating element (3) including a resistance heating wire (4) surrounded by and electrically insulated from a metal sheath (5), the heating element (3) being carried directly or indirectly on a metal base plate (1) for transferring heat from the heating element (3) to a medium to be heated by the device, wherein the heating element (3) is in thermally conductive communication with the base plate (1) via a heat diffusion layer (2), wherein the heat diffusion layer (2) is of a metal comprising copper. In preferred embodiments an underside of the heating element (3) contacts, or is directly attached to, the metal base plate (1) and the heat diffusion layer (2) wholly or partially overlies the heating element (3), or alternatively the heating element (3) is attached to the heat diffusion layer (2) which is in turn attached to the base plate (1).
