Installation – storage tank  

and solar controller

20mm thermal 

insulation around pipe

The storage tank “flow” connection is to be piped to the 
inlet of the collector array. The outlet of the collector array is 
to be piped to the “return” connection on the storage tank 
and shall have continuous fall back to the storage tank. It 
is recommended that the sensor cable be run at the same 
time as the collector piping for convenience. Ensure that the 
sensor cable is installed neatly, kept out of the way and is not 
in contact with any potentially hot surfaces or copper piping.
If the tank is not to be installed until a later date, ensure that 
the sensor plug is well protected and waterproofed (e.g. put in 
plastic bag and cable tied in a safe location) until final assembly.

An isolating and not return valve must be installed on the 
inlet to the hot water system. If it is possible that the supply 
pressure could exceed 600kPa, a pressure limiting valve shall 
also be installed on the inlet piping. A pressure relief valve 
may also need to be installed on the inlet to the hot water 
system under local plumbing requirements. 
If the hot water system is installed in a bad water quality  
area where regular flushing is required due to sediment 
build-up, a drain cock or valve is also to be installed on the 
inlet piping.

On the storage tank return connection install a 1/2" copper 
union, 1/2" nipple and 3/4" to 1/2" reducing bush with 
appropriate thread sealant.

Installation of pipe work between the collectors and 
storage tank

The pipe work between the collectors and the hot water 
storage tank is to be made of copper and be a minimum of 
1/2" in diameter. It shall be covered with 20mm thick thermal 
insulation to maintain the efficiency of the system, prevent heat 
loss and to allow the proper operation of the freeze protection. 
Any piping insulation that will be exposed to sunlight must 
also be UV resistant. The copper pipes shall be supported by 
saddles and installed neatly with no sharp bends. The pipes 
shall not exceed the recommended length of 10m (20m total) 
and the height difference between the storage tank and the 
collectors must not be greater than 9 meters. Penetrations 
through the roofing material must be neat, kept as small 
as practical and made at the high point of the roof tile or 
metal sheet. Exposed insulated pipe work between the solar 
collectors and the penetration through the roofing material 
should be kept to a minimum to maintain the aesthetics of the 
installation. The penetrations are to be waterproofed upon 
installation of the pipe work and a boot shall be installed to 
prevent any water from leaking into the premises.
