Then the cold liquid inlet is at one side and the hot liquid
outlet is at the second side.
At the inlet into a collector array, a brass elbow shall be
installed to the connecting pipe.
A brass pipe cross shall be installed at the outlet from
the collector array that will enable connection to the
piping, sheath installation for the collector temperature
probe and eventual installation of a ball valve and an
automatic air discharge valve. The brass elbow and
pipe cross are involved in Regulus connection kit, code
14618.
All solar components must be carefully and safely sealed
and must be made of material resistant to glycol and
temperatures up to 160 °C. For connection piping we
recommend using KOMBIFLEX stainless-steel flexible
pipes, or copper pipes connected by soldering.
In no event plastic tubes can be used for inlet/outlet pi-
ping as they do not meet the operation requirements for
solar thermal systems.
Pipes for collectors can be lead through disused chim-
neys, ventilation shafts or grooves in a wall. In order to
prevent high thermal losses through convection, open
shafts shall be properly sealed. Also thermal dilatation
shall be remembered and pipes fitted with compensators
or other compensation elements.
Piping shall be connected to the house earthing.
Pipes of the solar thermal system must be fitted with
thermal insulation, so that thermal dissipation from the
pipes does not deteriorate a total efficiency of the solar
thermal system. The thermal insulation must be resistant
to temperatures up to 160 °C, for outdoor piping also a
UV protection is essential as well as non-deliquescence
of the material. For indoor piping, the thermal insulation
should be at least 13 mm thick, for outdoor piping at
least 19 mm.
