INSTALLATION – SOLAR COLLECTORS
Maximum Height to Collectors
The maximum height of a pumped open circuit solar installation, from the solar
controller (circulator) to the top of the solar collectors, is determined by the
maximum recommended total pipe length for the system and the water supply
pressure.
The maximum recommended total pipe length of the solar circuit should not be
exceeded and a minimum water supply pressure of 200 kPa should be available
at the inlet to the system, otherwise the system performance may be reduced or
the solar circuit may not be purged of air during the commissioning of the system.
