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.

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.

A roofing tile comprising a tile body and a thermal conduction device on the underside, in use, of the tile body in which the thermal conduction device, comprises thermal conduction sheets including partly stamped out and bent up anchoring sections and edge portions which are embedded into the tile body for securing the sheets to the underside of the tile body, the sheets including on one longitudinal side beads of quadrant shape from which two generally planar sheet-metal contact strips protrude facing each other and extending downwards away from the tile body, the contact strips extending basically over the whole length of the tile body and being generally trapezoidal with the longer of the two parallel sides adjacent a tail area of the tile and with the ends of the contacts facing the tail area of the tile being set back from the corresponding edges of the thermal conduction sheets, lower corner areas of the contact strips adjacent to a head area of the tile being bent outward and the contact strips being resiliently splayable for the purpose of slipping them onto a heat carrier medium pipe so that, in use, the contact strips engage both sides of the heat carrier medium pipe which is fixed to the roof structure for transferring heat to the pipe.
