HOW YOUR WATER HEATER WORKS
10
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
winter months. The Premier Loline water heater is suitable for the heating unit
to be connected to a continuous or an extended Off-Peak electricity supply.
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 upper front cover. The water temperature is automatically controlled
to the thermostat setting when the booster heating unit is energised.
MANUAL CONTROLS
An isolating switch is installed in your electrical meter box for your solar storage
tank. Rheem recommends an additional manual isolating switch be installed in
the power supply circuit to the solar storage tank. This booster switch should be
installed in a convenient location such as the kitchen or laundry and will enable
control of the electrical boosting during periods of poor solar gain.
A suitably rated single-pole
on / off switch or timer control switch should be
used to control a booster heating unit connected to an Extended Off-Peak
electricity supply. A booster heating unit connected to a continuous electricity
supply should be controlled by either a suitably rated single pole
on / off switch
or “One Shot Control” switch or timer control switch .
The amount of water heated by the raised booster heating unit of your Premier
Loline storage tank will be 125 litres (270 model).
MANUAL ON/OFF SWITCH
a) Continuous or Time of Use Tariff Connection
Electricity will be available for the booster
heating unit at all times. Operate the
booster switch to activate the auxiliary
booster heating unit when the hot water
falls below an acceptable temperature. The
amount of water heated depends on your
installation (refer to
“Manual Controls” on
page 10).
If on a ‘Time of Use’ tariff, then it may be
cheaper to use the booster at particular
times (check with your local Electricity
Supply Authority for tariffs at different hours
of operation).
