Abstract

An electric heating element (20), the element (20) comprising; an electrically non-conducting support comprising a plurality of segments (22), each segment (22) being moveably connected to two neighbouring segments (22) and capable of one dimensional motion in respect thereto, the outer surface of each segment (22) including a ridge (27) extending helically about the segment (22), the ridges (27) of neighbouring segments (22) co-operating together to form a helical channel a first electrically resistive wire (21) heating portion helically wound about the support within said helical channel, the segments (22) defining a further channel along the axis of the helix, said further channel retaining a second electrically resistive wire (21) heating portion spatially separated from the first resistive wire portion, the first and second portions being operatively connected to define an electrical pathway.
