<p>A die-cast heater (2) for a liquid heating vessel comprises a heating element (4) arranged in substantially a single turn about the periphery of the heater and having overlapping end portions (34). The overlapping end portions (34) allow the heating element (4) to heat substantially the entire periphery of the heater (2). The die-cast element carrier (3) comprises integral bosses (30) which are in direct thermal contact with the heating element (4) and serve as thermal contact locations for bimetallic actuators of a control for the heater (2). The boses (30) smooth out transient fluctuations in the temperature registered by the bimetallic actuators to prevent inappropriate operation.</p> |
