INSTALLATION – SOLAR STORAGE TANK
24
SOLAR WATER HEATER STORAGE TANK LOCATION
The solar storage tank is designed to be installed on the roof directly coupled to the solar collectors. The solar
water heater should be installed close to either the most frequently used outlet or the previously installed water
heater in a retrofit installation if existing pipe work is to be utilised, and its position chosen with safety and
service in mind. The solar water heater should be installed with as close to a north facing aspect as possible.
Refer to “Solar Collector Location” on page 32. The solar storage tank must not be installed inside the roof
space.
The solar water heater system, including the interconnecting solar pipe work, must not be installed with an
inclination of less than 10°, otherwise the water will not thermosiphon efficiently through the collectors.
Clearance must be allowed for servicing of the solar storage tank.
Make sure the temperature pressure relief valve lever is accessible
and the side cover, thermostat and booster heating unit can be
removed for service. You must be able to read the information on the
rating plate. If possible leave side room of one solar storage tank
length so the anode can be inspected or replaced.
Remember you may have to remove the entire solar storage tank
later for servicing. The solar storage tank must be capable of being
removed without structural alteration to the building or major
alteration to the piping.
For a single water heater installation, refer to the diagrams on
pages 30 to 31. For multiple water heater installations, also refer to
the instructions on pages 52 and 53.
The solar storage tank must be installed horizontally level. Remember all local authorities have regulations
about putting water heaters into roof spaces.
MAINS WATER SUPPLY
Where the mains water supply pressure exceeds that shown in the table below, an approved pressure limiting
valve is required and should be fitted as shown in the cold water connection detail on page 47.
Model
180, 300
Temperature pressure relief valve setting
1000 kPa
Expansion control valve setting *
850 kPa
Maximum mains supply pressure
With expansion control valve
680 kPa
* Expansion control valve is supplied with the water heater installation pipe kit.
TANK WATER SUPPLY
If the water heater is supplied with water from a tank supply and a pressure pump system is not installed, then
the bottom of the supply tank must be at least one (1) m above the highest point of the hot water plumbing
system, including the water heater. Care must be taken to avoid air locks. The cold water line to the water
heater should be adequately sized and fitted with a full flow gate valve or ball valve.
REDUCING HEAT LOSSES
The cold water line to and the hot water line from the water heater must be insulated in accordance with the
requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed.
The pipe work between the solar storage tank and the solar collectors may be required to be insulated. Refer
to “Warning: Plumber Be Aware” on page 34.
