Location
General:
Solar water heater storage tanks are
normally installed outdoors. The storage tank
should be located as close as possible to
the most frequently used hot water outlet.
Consideration should be given to the route
taken by solar collector piping and drain
lines.
Ensure the compliance plate and associated
warnings are clearly visible.
The storage tank must be accessible without
the use of a ladder or scaffold. Adequate
clearance must be available for service to the
solar controller, circulation pump, relief valve,
sacrificial anode, and the electrical cover of
electric boosted models.
Indoor Installation:
Solar water heater storage tanks may be
installed indoors. A properly drained safe tray
must be installed where property damage
could occur from water spillage. Refer to
AS/NZS 3500.4 for further information.
Note - the warranty will not cover damage
due to leakage of the water heater if a
properly drained safe tray has not been
installed.
Refer to local regulations before installing the
storage tank in a roof space.
Water Heater Support:
The water heater storage tank must be
installed on a flat, solid supporting surface.
The pipework must not be used to support
the water heater. The installation of the
storage tank must not compromise the
structural integrity of the building.
Where the storage tank is subjected to wet
conditions, a plinth should be installed under
the storage tank.
Gas Boosted Models:
The instantaneous gas water heater must be
installed
outdoors
. It must also be located
to ensure that the connection pipe to the
storage tank is no more than 2 metres in
length.
The location of the flue terminal must comply
with the requirements of AS/NZS 5601.1
or local rules and regulations. Refer to the
instantaneous gas water heater Installation
Manual for further information.
Solar Collectors:
For maximum solar gain, solar collectors
should face no greater than 45° east or west
of true north.
Please refer to AS/NZS 3500.4 for further
information relating to solar collector
positioning.
