Triple Solar assembly instruction PVT heat pump panels UK January 2021
•
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 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.
•
Indoors, keep enough distance between the pipes and the wall so that the insulation can still
go between them.
When connecting several heat pump panels, consideration should be given to limiting pressure
loss. The advice is a connection according to Tichelmann. For a pitched roof installation see
figure 8.1-a.
Tichelmann is not always necessary for smaller fields.
For a pitched roof connecting Tichelmann is mandatory:
•
≥5 rows of panels
•
≥5 panels per row
When
propylene glycol
is used, Tichelmann is required:
•
≥4 rows of panels
•
≥4 panels per row

double sided Tichelmann connection
A single-sided Tichelman connection is a possibility if it is difficult to fit in with a pitched roof.
See figure 8.1-b.
