PCT No. PCT/NO96/00007 Sec. 371 Date Jul. 11, 1997 Sec. 102(e) Date Jul. 11, 1997 PCT Filed Jan. 12, 1996 PCT Pub. No. WO96/21828 PCT Pub. Date Jul. 18, 1996An electric heater for ceilings which emits radiant heat includes a radiant plate having heating elements which radiate in a downward direction. The radiant plate is mounted to a top part by a number of elastic/flexible brackets, including pivotable and non-pivotable brackets. The brackets allow the radiant plate to move laterally outward in a horizontal plane when the radiant plate is heated to prevent twisting or other deformation of the radiant plate. The pivotable brackets are mounted near the ends of the heater on all four sides to accommodate expansion of the radiant plate in a horizontal plane. The non-pivotable brackets are mounted at the midpoints of the ends of the heater. |
