1. An apparatus for heating air comprising an elongate body adapted to receive, or integrally formed with, two or more heating elements in thermal contact therewith, said body comprising a plurality of heat exchange fins defining a plurality of axially extending flow passages therebetween for heating air flowing therethrough,
and wherein the elongate body comprises two laterally spaced tubular recesses extending parallel to the longitudinal axis wherein each recess contains one of the heating elements such that the heating elements are in direct thermal contact with the elongate body, wherein the elongate body is formed from two halves separable in a plane coincident with the longitudinal axis of the elongate body and the tubular recesses such that the halves of the body can be separated to insert or remove the heating elements, and wherein each half of the body comprises a box section shaped central region defining a flat outer flange extending along the length of the elongate body and an inner flange, each flange having apertures formed therein for receiving fasteners for securing the two halves of the body together, wherein the apertures in the outer flange have a larger diameter than the apertures in the inner flange and are in alignment with the apertures in the inner flange to allow insertion of the fasteners and access to the fasteners.
