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").
• Drill at least two bore holes, bearing in mind the di-
mensions of the unit and its connections (1).
• A separate bore hole is required for each heat source
pipe.
• Special pipe lead-throughs must be used if there is a
risk of ground water penetration (follow the
manufacturer's details).
• 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).
• Install diffusion-tight insulation pipes from heat sour-
ces in cellar areas, as condensation will otherwise
form (pipe temperature may be as low as -15 °C).
