<p>A panel radiator comprises a radiant panel 1 against the back of which a tube system 2 is secured by spring clamps 9. The tube system 2 comprises a plurality of parallel and spaced apart rectangular longitudinal tubes 3 lying flat against the panel 1, and a plurality of connection tubes 5 extending transversely between the tubes 3 and interconnecting the longitudinal tubes in such a manner that a heating medium will flow through the system 2 in a serpentine manner, flowing through successive longitudinal tubes 3 in opposite directions. The connection tubes 5 extend between holes 8 in the sides 7 of the longitudinal tubes 3 near the closed ends 4 of the tubes 3, and are narrower than the sides 7 in the direction perpendicular to the panel 1. <IMAGE></p> |
