Connecting the collector hose to the heat pump
It is important that the collector hose has been pressure tested before it is
connected to the heat pump. Pressure testing is carried out by the boring
company or excavating company and determines whether the hose is in
one piece and works as it should. When laying the ground heat hose the
hose is usually pressurised during the laying process.
Another leakage test should be performed on the collector hose before
commissioning the heat pump.

Note
Non-infl ammable pipe material must be
used when routing the pipes indoors.
When plastic hose is used indoors
this must be protected by 40 mm fi re
resistant, mineral wool sheet, EI30.
The drawings below show how to run the collector hose in the ground and
through a wall. The soil fi lling around the hose must not contain stones. If
the hose is ploughed down, you must use equipment that guarantees the
hose is laid at the right depth.
