6 Piping installation6.1 Information collector pipeCaution! Local rules and regulations related to type of collector must be followed.Borehole collector: Fully welded plastic pipe collector (PEM PN 6.3) according to the applicable local and nationalregulations with factory manufactured return bend.Ground collector: Fully welded plastic pipe collector (PEM PN 10) according to the applicable local and nationalregulations.In countries where frost damage occurs, the collector pipe beside an outer wall (minimum 2 metres) must be insu-lated in such a way that frost damage is prevented. This applies regardless of ground, rock or lake heat.Minimum shaft depth between the energy well and the building is 0.5 m. If burial to that depth is not possible thepipes must be protected against any external mechanical damage.>0,5m>2,0mFigure 16. Shaft depth for, and insulation of, collector hoses6.2 Connection of several brine coilsWhen several brine coils are used for a heat pump installation, regardless of what heat source is used, the length ofthe coils must not exceed the values in the following tables. The coil lengths are based on ethanol 30% at 0°C.For hoses of type PEM DN 32, Øi = 28.0:Table 2.
