Abstract
A radiant electric heater for use in a smooth top cooker includes a base of electrical and thermal insulating material and two heating elements supported on the base. One of the heating elements is energisable independently of the other element, for example to permit the heater to be adapted to different size cooking utensils. A peripheral wall of thermal insulating material extends laterally around the heating elements and a dividing wall is arranged between the heating elements such that, in use, separate and distinct heating zones are formed on the smooth top of the cooker. The dividing wall is received in the base of electrical and thermal insulating material and is retained in the base by friction. The dividing wall may additionally be constructed and arranged as a barrier effectively only to thermal convection currents generated in the heater.
