INSTALLATION – SOLAR STORAGE TANK
28
Circulated Hot Water Flow and Return System
– Solar Water Heater with In-series Boosting
Temperature Limiting Device
A temperature limiting device cannot be installed in circulated hot water flow and return pipe work. The
tempered water from a temperature limiting device cannot be circulated. Where a circulated hot water flow and
return system is required in a building, a temperature limiting device can only be installed on a dead leg,
branching off the circulated hot water flow and return pipe.
If circulated tempered water were to be returned back to the secondary or in-series booster water heater, then
when the hot taps are closed no water will be supplied to the cold water inlet of the temperature limiting device
whilst hot water will continue to be supplied to the hot water inlet of the temperature limiting device.
This condition may result in either water at a temperature exceeding the requirements of AS/NZS 3500.4 being
delivered to the hot water outlets in the ablution areas, or the device closing completely and not delivering
water at all, or the device failing. Under this condition, the operation and performance of the device cannot be
guaranteed.
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 full length of the solar hot and solar cold pipes between the solar storage tank and the solar collectors
MUST BE insulated. Refer to
“Warning: Plumber Be Aware”
on page 38.
BOOSTER HEATING UNIT
The booster heating unit is for heating the water at times of low solar energy gain, such as during very cloudy
or rainy weather, or during the colder months. Refer to
“Connections – Electrical”
on page 43 for electrical
connection requirements and control options of the booster heating unit.
If this water heater is installed with an in-series booster, then the electric booster heating unit in the solar
storage tank will not need to be connected to a power supply.
