<p>A protective layer, for transferring surface forces into the insulating underlay of a heatable flow, is made up from brick split tiles (4) forming open laying shafts (10) to fit the pipe grid. The U-shaped aluminium profiles (5) have flat, equal-width surfaces (9) formed, on the rear side of the depression (6). The gutter-shaped part of each profile is inverted from above, across the heating pipe (3), so that its inner walling tightly encloses the pipe. The formed surfaces of the profiles cover the laying shafts from the top, and the adjoining tiles, in a wide area. Heat resistance to the upper flow is reduced, enabling heating-medium temperature to be lowered and heat-pump systems to be used.</p> |
