<p>Electrical ceiling heater panel for radiant heating, comprising a relatively elongated radiant heating element (22) having a radiation emitting surface adapted to face generally downwards in the mounted position of the panel, said surface being preferably provided with longitudinal ribs (10A, 10B), at least one electrical heater element (25, 26) being in close heat conductive contact with the radiant heating element (22) and a surrounding insulated housing (5, 7, 15) having means (2, 3) for suspending the panel from a ceiling (1). The radiant heating element (22) at its longitudinal edges has engagement parts (22A, 22B) for cooperation with longitudinal edges (19A) of an element box (19) built up of sheet material and having a sufficient rigidity to keep the radiant heating element (22) in a correct position during operation. The radiant heating element can be displaced somewhat in its longitudinal direction with respect to the element box, and at each end of the element box there is provided a plate-shaped bracket (18) standing generally in a plane normal to the longitudinal direction of the panel and adapted to be somewhat resilient in this direction as well as being attached to the adjacent end of the radiant heating element (22) at the outer edges thereof.</p> |
