The system has a prefabricated heating element comprising loop-like round- and/or oval tubes between web grid carrier mats and alternately running at middle of the heating element for engaging a longitudinal-sided intermediate space. The tubes are provided for flowing with warm water in an opposite or parallel flow direction. The tubes are arranged between the mats such that the tubes alternately run at breadth of the mats and lie adjacent to each other in the middle of the element. The tubes form opposite or parallel flowing water bodies ending at flow- and return lines. |
