A roof tile (10) of concrete has a thermal conduction device if the form of metal plates (20a, 20b) are attached on its underside. Flat metal contacts (30a, 30b) project out from the bottom and are designed to be snapped onto a pipe (40) that extends up the roof and that supports a heat-carrying medium. The pipe is a part of a line system attached to the roof structure to collect heat absorbed by the roof tiles. From the outside, the tiles have the same appearance as normal roof tiles.<IMAGE> |
