Roofing tile with thermal conduction device

摘要

A concrete roofing tile (10) has a thermal conduction device in the form of metal sheets (20a, 20b) attached to its underside. Planar metal contacts (30a, 30b) project from the underside of the sheets and are adapted to clip on a pipe (40) which extends up the roof and carries a heat carrier medium. The pipe is part of grid fixed to a roof structure for collecting heat absorbed by the tiles. The tiles have the appearance of ordinary roofing tiles from the outside.
