Solar Monitor LED operation
The LEDs on the Solar Monitor, located on the side of the solar control unit, operate to show the operational
mode of the water heater. Refer also to
on page 11.

ELECTRIC BOOSTING
Water stored in the solar storage tank can be heated by an electric 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.
The amount of water heated by the raised booster heating unit of the Streamline solar storage tank is
220 litres (410 model), 170 litres (320 model) or 140 litres (270 model).
The water heater is most suited for the booster heating unit to be connected to either a continuous, or a time
of use, or an extended Off-Peak (overnight and day) electricity supply. A timer can also be used to control
the boosting periods and help maximise solar savings. Refer to
on page 8.
The booster heating unit may be connected to an Off-Peak (overnight) electricity supply, however this will
only allow the booster to heat the water overnight. If this type of connection is considered, care must be
taken to ensure there is sufficient boost capacity to meet
the household‟s full day and night‟s hot water
supply during periods of no or low solar gain, particularly in cold weather.
The booster heating unit is controlled by an electric thermostat. The thermostat and its over temperature
energy cut out are mounted on the solar storage tank behind the front cover. The water temperature is
automatically controlled to the thermostat setting when the booster heating unit is energised.
