<p>Fluid flows through an underside ducting system, connected to a device for extracting heat from natural radiation energy and convection, in a roof with covering elements overlapping like scales as in 3014075. An intervening space (4) between a higher and a lower covering element (2,2',2") contains at least one resilient bearing element (5,5'), in contact with adjacent covering element surfaces, to hold pipes (6) belonging to the ducting system. Each pipe may have resilient ribs as a bearing element, rotatably mounted on it, pref. on both sides, and enclosing it hinge-fashion. The mounting area of each rib may have retainers to fix the enclosed pipe in place.</p> |
