Abstract
A radiant electric heater arrangement for a glass-ceramic top cooking appliance includes a heater in the form of a dish-like support supporting a first heating element and a second heating element. The first heating element has a predetermined minimum operating life expectancy at a predetermined optimum operating temperature. During user-selectable periods of boost heating the first heating element is connected independently to a voltage supply and operates at a first temperature higher than the predetermined optimum operating temperature. In contrast, during user-selectable periods of normal heating, the second heating element is connected to the voltage supply in series with the first heating element, the first heating element operating at a second temperature lower than the predetermined optimum operating temperature.
