The given required area for geothermal heat pumps is rela-
tes to average ground conditions (Soil, clay). The required
collector size and therefore the area has to be increased
for poor grounds (gravel). The circuits have to be bedded in
fine sand (0,3 0,5mm).

Pipes from the manifold towards the cellar
An example for a TERRA 8 S-HGL heat pump with
4 circuits and a manifold connection inside the cel-
lar.
For a length of 2m, where the pipes are brought
together, they have to be insulated.
The connection pipes have to be insulated with
suitable insulation, galvanized pipes can't be
used.
A minimum distance of 1m has to be provided to
any water supply and drainage pipes as well as
to walls
Openings inside the wall have to be insulated
and made water proof.
A warning tape has to be bedded 0,5m above
the pipes.
An installation plan and photos have to be ma-
de.
The manifold connection can also be outside the
house inside a manhole.
