<p>A convection guide for improving the efficiency of a radiator for heating a building. The guide comprises at least one guide element having a convection surface for forming a convection path with said radiator, thereby to allow air in said path to be heated by said radiator, and to be guided by said convection surface under convection. The convection surface comprises a plurality of substantially continuous undulations arranged to induce non-linear passage of said heated air over said convection surface.</p> |
