4.2.1.2 Installation
Note:
• Make sure each circuit can be locked, filled and emptied individually.
• Make sure a distributor and collector is installed at a very top of the pipe to ensure correct ventilation and
easy inspection.
• Do not use galvanized pipes. Pipes must be of suitable plastic.
• If more than one pipe circuit is used, the length of each pipe circuit should not exceed 100 m. All pipe
circuits must be the same length.
• Make sure there is a minimum distance of at least 1 m to water-carrying pipes or foundation to avoid
frost damage.
1. Install the geothermal heat collector in an open space or a trench system, depending on the size of the property.
2. Put pipes horizontally in the ground, the perfect depth is 1,5 to 2 m but not deeper than 5 m. The distance between
the pipes should be minimum 0,8 m.
3. Install the air vent at the highest point of pipe circle.
4. Insulate all pipes.
5. Connect one side of the PE-pipe with the help of an adapter to the inlet of the geothermal heat exchanger connection
(A), ¾ inch tapered external thread.
6. Connect one side of the PE-pipe with the help of an adapter to the outlet of the geothermal heat exchanger connec-
tion (B), ¾ inch tapered external thread.
