Abstract
A radiant electric heater assembly for a glass ceramic top cooker includes four radiant electric heating elements and a thermal cut-out device. Associated with the termal cut-out device is a switching device for connecting the four heating elements in parallel with each other to give a first power level setting and for connecting the heating elements in a lower power configuration in which the elements are connected as two elements connected in series with each other and connected in series with a pair of elements connected in parallel with each other. When the thermal cut-out device detects a first predetermined temperature the heating elements are connected in the lower power configuration until such time as the thermal cut-out device detects a second predetermined temperature, lower than the first predetermined temperature, when the heating elements are reconnected in the configuration of the first power level setting.
