4.5 Preparatory work in the installation area

Fig. 4.3 Preparatory work in the installation area

• Make sure that the substrate is sufficiently stable (see

Chap. 4.2 "Requirements for the installation site").

• Make at least two bore holes, bearing in mind the di-

mensions of the unit and its connections (1).

• Each pipe from the heat source requires its own bore

hole.

• Special pipe feedthroughs must be used if there is a

risk of ground water penetration (follow the manufac-

turer's instructions).

• Take account of the distances to the core barrels for

the rest of the installation.

• Pass the heat source pipes (2) from the outside into

the installation area.

• Lay the heat source pipes (2) centrally in the bore

holes (1) to facilitate all-round thermal insulation.

• Seal the annular gap (1) as shown with foam insulation

(e.g. PE foam) (3).

• Insulate the heat source pipes in cellar areas against

vapour diffusion, as condensation will otherwise accu-

mulate (pipe temperature can be as low as - 15 °C).
