ABSTRACT:
A radiant heater for use in "smooth top" cookers of the type in which a smooth top normally of glass ceramic overlays one or more generally circular electric heater elements supported on a layer of thermal and electrical insulating material such that the element is spaced from the top.
The radiant heater comprises at least two heater elements (10 and 12) supported on a base of electrical and thermal insulating material (4) at least one of which elements is energizable independently; and a peripheral wall (8) of thermal insulating material surrounding the elements.
The radiant heater of the invention is used in "smooth top" cookers and is covered by a top which is transparent and substantially non-absorptive to radiant cooking heat so that only the areas of the top which are exposed to the element will be heated. Preferably, the utensil being heated should have a base equal to the heated or exposed area of the top for maximum efficiency.
