The known system requires considerable care when laying. While it's not that difficult Lay the straight parts of the underfloor heating pipes, at the tJmkehrechlauf and others However, changes in direction occur again and again, especially in the case of plastic pipes, that the Underfloor heating pipes are temporarily or excessively bent on sour, so that it kinks the • Underfloor heating pipes are coming. Thee in particular is at Wicht- experts the case.

It is the object of the invention to provide a way of laying Zfloor heating pipes in which the work of applying the brackets to the insulation is eliminated and improper laying with too narrow baths is definitely avoided. Furthermore, the laying should be made easier overall and, in particular, should be able to be carried out without errors by the non-specialist.

To facilitate laying, insulating layers are already known in which there are laying depressions running in parallel. Because of the insulating material, which is located between the underfloor heating pipes, However, if the heat distribution in the floor is relatively poor, this installation also prevents
