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 Premier Loline closed circuit solar water heater is designed for the solar collectors to be roof
mounted and the solar storage tank to be installed at ground or floor level. The electric boosted solar storage
tank is suitable for installation either outdoor or indoor and with either Rheem S200, T200, HBT200 or
TBT200 solar collectors. The system is suitable for installation in areas subject to frost or freeze conditions.
Freeze conditions occur below 6°C.
MAINS PRESSURE
The water heater is designed to operate at mains pressure by connecting directly to the mains water supply.
If the mains supply pressure in your area exceeds that shown on page 20, a pressure limiting valve must be
fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
SOLAR OPERATION
The Rheem Premier Loline closed circuit solar water heater has its vitreous enamel lined solar storage tank
installed at ground or floor level, remotely from the solar collectors. This water heater is an indirect solar hot
water system with a heat exchanger in the solar storage tank.
The heat exchanger is filled with closed circuit fluid and is connected to
the solar collectors forming a closed circuit. 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.
As the sun heats the solar collectors, the increase in temperature
activates the pump. The pump switches on whenever the solar
collectors are hotter than the water in the tank. The pump moves the
closed circuit fluid from the solar storage tank heat exchanger through
an insulated copper pipe to the solar collectors to be heated by the
sun‟s energy and then back to the heat exchanger. Heat transfers from
the closed circuit fluid in the heat exchanger to the water stored in the
solar storage tank.
This process continues while solar energy is available and until the
water in the solar storage tank reaches a temperature of approximately
75°C. The pump is then deactivated and the closed circuit fluid in the
solar collectors and solar pipe work drains back into the heat
exchanger in the solar storage tank.
The closed circuit provides protection to the solar collectors and solar circuit in harsh water areas. The drain
back principle provides protection to the system in freezing conditions.
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 Premier Loline closed circuit 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) 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.
