Routing the connection lines
Caution.
Risk of material damage caused by
ground lifting up as a result of frozen
ground.
At operating temperatures close to freezing
level, the ground in the area of the PE pipes
may freeze and therefore damage the struc-
ture as a result of the ground lifting up.
▶
Insulate all of the PE lines that are to be
routed under buildings, terraces, path-
ways, etc. so that they are vapour-diffu-
sion-tight.
▶
If possible, route PE pipes in the ground
with a clearance of 70 cm from each other
and from adjacent supply lines (except for
electrical lines).
The total length (connection lines from the heat pump to the
product and from the product to the heat pump) must be no
greater than 60 m.
▶
Keep the clearance between the product and the heat
pump as short as possible and minimise the use of el-
bows and angles. This is because each additional pres-
sure loss that is caused by the use of these reduces effi-
ciency.
▶
Route the PE pipes in accordance with the applicable
technical directives.
▶
For a total line length of between
≥
20 m and 60 m, use
a PE pipe with DN 50 (e.g. PE 80/100, outer diameter
50 mm, wall thickness 4.6 mm). Up to a total line length
of
≤
20 m, you can also use a PE pipe with DN 40
(e.g. PE 80/100, outer diameter 40 mm, wall thickness
3.7 mm).
▶
When using more than eight PE elbows, use an extra
2 m of pipeline for each elbow.
▶
When using copper pipes, use only copper pipes that
have a cross-section of
≥
35 mm. If you use a smaller
cross-section (e.g. copper 28 mm), this will result in pres-
sure losses (2 m copper 28 = 8 m copper 35).
Note
If the prescribed line cross-sections are not
complied with, this results in efficiency losses
and reduced annual operating figures.
▶
If required, when routing the PE pipes above-ground,
ensure that they are protected against UV radiation.
