Abstract

A heating element assembly comprises a sheathed heating element (4) having a hot return portion (14) brazed onto a head (6). The head (6) has a rib (22) formed on the front face of a dimple (16) which acts as a mounting location (18) for a bimetallic actuator (20). The element (4) has an increased watts density in the hot return portion (14) relative to the rest of the element, and the rib (22) acts to offset the actuator mounting location (18) from the hot return (14).
