The identifi ed surface requirement for geothermal
pumps is based on average soil conditions (soil,
loam). In the case of poor soil (stony), the required line
length, therefore also the surface, should be enlarged
and the pipes should be embedded in fi ne-grained
sand (cable sand 0.3 to 0.5 mm).
Contact your IDM partner for more information.
Note
- The installation should take place several months
before the heating period. Corresponding prepara-
tion times need to be taken into account during the
overall planning process.
- Plants with deep-growing root structures must be
avoided in all cases.
- Rainwater must not be diverted using drainage as it
is required to regenerate the ground.
- When back-fi lling, a signal band of approx. 0.5
above the pipeline should be laid to avoid subse-
quent damage.
- In the case of surface collectors, the overlying sur-
face must not be closed off (e.g. by asphalting).
