Triple Solar assembly instruction PVT heat pump panels March 2020
8. Connecting the pipes
Material and position
•
When connecting the heat pump to the heating circuit, always use a bronze connector between
the copper pipes of the heat pump and the c steel of the heating circuit.
•
The piping between the heat pump panel and the heat pump can be realized in different ways:
Stainless steel pipe, copper pipe, plastic multilayer pipe (PEX) or plastic PP-R pipe. (do not use C
steel)
•
Plastic pipes lying in the sun should always be protected against UV light by means of a UV-
resistant sheath or UV-resistant paint. The plastic pipes must be suitable for the source fluid.
•
Make sure that the flow in the source circuit is limited as little as possible, e.g. by using knees
and/or pipes with an inner diameter that is too small.
•
Do not install any piping under the panels. It blocks the air flow underneath the panels and makes
maintenance difficult.
When connecting several heat pump panels, consideration should be given to limiting pressure loss. The
advice is a connection according to Tichelman.
•
For a pitched roof installation see figure 8.1-a.
•
Tichelman is not always necessary for smaller fields.
•
With a flat roof installation in rows of 2 panels, the return pipe is always at the highest point of
the panels.
Connecting Tichelman is mandatory:
•
≥5 rows of panels
•
≥5 panels per row
When
propylene glycol
is used, Tichelman is required:
•
≥4 rows of panel
s
•
≥4 panels per row
