ABOUT YOUR WATER HEATER

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

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 Loline solar storage tank is 220 litres
(410 model), 170 litres (325 model) or 140 litres (271 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
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.
HOW HOT SHOULD THE WATER BE?
The solar control unit will circulate water through the solar collectors until a
temperature of 70°C to 80°C is reached.
During periods of low solar energy gain, the water temperature can be boosted
by the thermostatically controlled electric booster heating unit. Refer to
Control"
on page 8.
Rheem recommends the thermostat is set at 60°C to maximise solar
contribution.
Note: AS 3498 requires that a water heater provides the means to inhibit the
growth of Legionella bacteria in potable water. This water heater can satisfy this
AS 3498 requirement provided the electric booster is energised for a sufficient
period each day and the electric booster thermostat setting is 60°C or higher.
If this water heater is installed with an in-series continuous flow gas booster, then
this requirement of AS 3498 can be satisfied provided the booster is energised,
its preset outlet temperature setting is 70°C or higher and a remote temperature
controller is not used.
If this water heater is installed with an in-series storage booster, then this requirement of AS 3498 can be
satisfied provided the storage booster is energised and its thermostat setting is 60°C or higher.
