ABOUT YOUR WATER HEATER

BOOSTER CONTROL
An isolating switch is installed in the electrical meter box for the solar storage tank. This should be left switched
on to allow the booster heating unit to operate if required. 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. The
booster heating unit will only activate if heating is required and power is available from the switchboard. When
the water is below the thermostat setting, the booster heating unit will turn on and heat the water. The booster
heating unit will automatically turn off when the temperature of the water reaches the thermostat setting.
Leaving the isolating switch switched on will also provide a sufficient period of time each day for the booster
heating unit to operate, if required, to satisfy the requirements of AS 3498.
The amount of water heated by the raised booster heating unit of the solar Hiline storage tank will be 180 litres
(300 litre model), or 90 litres (180 litre model).
Timer Control Switch
A suitably rated timer control switch can be installed and will help maximise energy savings with an electrically
boosted solar water heater connected to a continuous, time of use or extended Off-Peak (overnight and
day) electricity supply. Further information for a licenced electrical worker on the recommended methods of
wiring the timer are outlined in “Booster Control” on page 51.
Programming the Timer
Power must be available to the timer control switch before the booster heating unit can be activated. The timer
control switch should be programmed:
• to suit the hot water consumption pattern of the household,
• with the end of the period to coincide with the commencement of the evening hot water usage,
A second period, such as prior to the morning hot water usage, may be necessary.
• to enable a boosting period of not less than the recommended continuous length of time for boosting, and
• for a period when power will be available to the timer.
Note: When daylight saving time applies, you may consider resetting the timer accordingly.
The recommended continuous length of time for boosting is:

The recommended boosting periods are sufficient to allow the booster heating unit to heat up the boost volume
of the solar storage tank to 60°C where the winter cold water temperatures do not fall below those shown. This
may be necessary during periods of very low solar energy gain through the solar collectors, such as during
constant rain or extremely cloudy weather, particularly in winter when the incoming cold water temperature is
lower. The period will also provide a sufficient heat up time for the electric booster to operate, if required, to
satisfy the requirements of AS 3498.
The booster heating unit will only activate if heating is required and power is available from the timer. When
the water is below the thermostat setting, the booster heating unit will turn on and heat the water. The booster
heating unit will automatically turn off either when the temperature of the water reaches the thermostat setting
or at the end of the timer period, whichever comes first.
