Abstract:
    An electrical resistance ceramic heating element comprises:- a) three or more ceramic legs comprising regions of the element in which at least the majority of the electrical heating occurs (hot zones), at least one of the legs being effectively entirely a hot zone and at least two of the legs each comprising a hot zone and a cold zone; b) a number of leg terminal portions less than the number of legs, for connection to a power supply; and, c) ceramic bridging portions providing electrical connectivity between the legs.
