ABOUT YOUR WATER HEATER
WATER HEATER APPLICATION
This water heater is designed for use in a single family domestic dwelling for the purpose of heating potable
water. Its use in an application other than this may shorten its life.
MODEL TYPE
Your Rheem
®
solar Premier™ Hiline™ water heater is designed for both the solar collectors and the solar
storage tank to be roof mounted. The solar storage tank has a Colorbond jacket and is suitable for
installation with Rheem S200 solar collectors.
The system is suitable for installation in areas subject to frost or freeze conditions. Freeze conditions occur
below 6°C.
This water heater is designed to be installed as an electric boosted solar water heater with its booster
heating unit connected to a power supply, however it may be installed with an in-series continuous flow or
storage booster.
If this water heater is installed with an in-series booster, then the electric booster heating unit will not be
connected to a power supply and the references to the electric booster heating unit, thermostat and boosting
controls in this Guide will not be applicable to the installation. For information relating to the function and
operation of the in-series booster, refer to the Owners Guide and Installation Instructions supplied with the
booster water heater.
SOLAR OPERATION
The Rheem solar Premier Hiline system has its stainless steel solar storage tank installed on the roof directly
coupled to the solar collectors. This water heater is an indirect closed circuit solar hot water system with a
heat exchanger in the solar storage tank.
The heat exchanger and solar collectors are connected by copper
pipe work and form a closed circuit which is filled with closed
circuit fluid. The closed circuit fluid is a solution of a blue, non-
toxic food grade propylene glycol concentrate mixed with water.
The closed circuit concentrate is used to lower the freezing
temperature of the closed circuit fluid and provides protection
against freezing. The closed circuit also provides protection to the
solar collectors and solar pipe work against harsh water
chemistry.
It works on the simple scientific fact that hot fluid rises. As the sun
heats the closed circuit fluid in the solar collectors, the increase in
temperature causes the fluid to rise through a copper pipe into
the heat exchanger where it transfers its heat into the water in the
solar storage tank. This allows cooler fluid from the heat
exchanger to flow into the solar collectors to be heated by the
sun‟s energy. This process continues while solar energy is
available.
Automatic safety controls are fitted to the water heater to provide safe and efficient operation.
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 solar Premier Hiline water heater is suitable for the heating unit to be
connected to either a continuous, or a time of use, or an extended Off-Peak (overnight and day) or an Off-
Peak (overnight) 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 side cover. The water temperature is
automatically controlled to the thermostat setting when the booster heating unit is energised.
