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.
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
24, a pressure limiting valve must be
fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
The supply pressure should be greater than 140 kPa for the rated flow and performance of a Rheem in-series
gas booster to be achieved.
MODEL TYPE
Your Rheem
®
Premier Loline 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
solar storage tank is suitable for installation either indoor or outdoor and with either
one only CSA2013 or two only NPT200 or LCS solar collectors. The system is suitable
for installation in areas subject to frost or freeze conditions. Freeze conditions occur
below 6°C.
This solar water heater is designed to be installed with either a Rheem continuous
flow 874820 or 874826 in-series gas booster mounted onto the storage tank or
installed remotely. If the in-series gas booster is mounted onto the storage tank, then
it is suitable for outdoor installation only.
The solar water heater may be installed with another suitable type of remotely installed
in-series continuous flow or storage booster. If the in-series water heater is other than
a Rheem continuous flow 874820 or 874826 in-series gas booster, then the references
to the in-series gas booster in this guide may not be applicable to the installation. For
information relating to the function and operation of the in-series water heater, refer to
the Owners Guide and Installation Instructions supplied with the water heater.
SOLAR OPERATION
The Rheem Premier Loline 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 a closed circuit 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 by insulated copper pipe work 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 and the water requires heating. 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.
