is a plastic arch with barbed hooks to
secure heating pipes in critical areas.
The matching system heating pipes with a diameter of 16 mm can be securely clamped
between the undercut studs. The spacing of the pipes at 75, 150, 225, or 300 mm must be
determined on the basis of the required heating output, as shown in the Schlüter®-BEKOTEC
heating diagrams starting on page 29. The spiral or snail pattern installation method shown
here is most suitable for achieving an even surface temperature. The heating pipes must be
installed 50 mm from upright construction parts and 200 mm from chimneys, open fireplaces
and ducts.
Note: It is important to minimise twisting in the heating pipes by turning the pipe coil in the
opposite direction. Tensions in areas where the pipes change direction can be minimised by
setting the pipe coil in the new direction.
Use the angle bracket Schlüter®-BEKOTEC-THERM-RH 75 to attach heating pipes installed
partially at 45° angles. The angle clips Schlüter®-BEKOTEC-THERM-ZW are used to attach
the heating pipes at the heating circuit distributor with a defined 90° angle. The clips allow for
exact insertion of the pipes into the relatively thin screed.
The smallest permissible bending radius “r” equals five times the outside diameter of the pipe
(with a diameter of 16 mm: smallest bending radius = 80 mm). Heating pipe angles must
always involve two studs (see pictures).

In spiral installations, the heating pipe is installed at double the installation distance to the
reversal loop. After reversal, the return leg is installed in the remaining spaces, which results in
the desired pipe spacing.
A form for a final pressure test can be found in Appendix II on page 78.
