Draw ducts / grooves onto the
wedi Building Panel for instal-
lation of the heating system.
Cut grooves using a router.
Cutting width should be the
same as the pipe width; cut-
ting depth should be at least
1/8” (3.2 mm) deeper. Make
sure at minimum a remain-
ing wedi Building Panel foam
thickness of 1/4“ (6.4 mm)
remains intact below the pipe.

Install tubing into the groove.
Fill tile adhesive into the pipe
duct to cover pipe and fill
voids.
Apply wedi’s wide self adhesive
reinforcement tape over the
installed ducts. You can then
start tiling. Tiles smaller than
4 × 4“ (101.6 × 101.6 mm)
should not be used over hy-
dronic system installation sur-
faces.
Installation of Hydronic / Water
heating systems using wedi Preline and
conventional wedi Building Panels
wedi Building Panels are ideally suited for use beneath floor and even
wall warming systems. The wedi Building Panels good insulation prop-
erties keep the heat away from the ground and reflect it back up in to
the room, regardless of whether you have a hot-water heating system or
an electric system. wedi Building Panels save energy and provide shorter
warm-up times around your heating system. The warmth is evenly dis-
tributed across the entire floor.
You can also use wedi building panel and customize channels for hy-
dronic tubes. Choose the appropriate thickness adding a minimum of
3/8 in. to the diameter of the tubes or pipe for insulation you want to
always keep strong enough below the channels ( add for any connector
fittings that may require deeper channels). You may also purchase wedi
Preline which features pre-made ducts for the hydronic system. Pictures
01-02 show how to use wedi building Panels with hydronic floor heating
systems. These steps are not required with Preline, which is equipped
with factory made channels that can be connected across boards.
For hot-water systems, ducts can be cut into the building panel and
other wedi elements quickly and easily. The wedi Building Panel serves
as a combined form of heat insulation and a base for installation of tile
and serves as waterproofing protection if needed.
