<p>The efficiency of panel radiator for a central heating system is improved by a fin sheet (6) attached to the radiator panel terminating at a level (D) short of the headers (3) defined at the top and bottom of the panel so that the air ducts (9) defined by the fin sheet and the panel are not constricted at their ends. In addition the corrugations are shaped and dimensioned so that the ratio of the air flow area of the ducts to the circumference of the ducts (S1/L1) is related to the ratio of the flow area of air flow plenums on the side of the fin sheet remote from the panel, to the length of the plenum circumference defined by the fin sheet (S2/L2). <IMAGE></p> |
