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 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 

NPT 200 solar collectors. 
 
A 52D series system does not have freeze protection. The system is not suitable for installation in areas subject 
to frost or freeze conditions. Freeze conditions occur below 6°C. The system has NO WARRANTY for freeze 
damage (refer to 

“Terms of the Rheem Warranty”

 on page 55). 

 
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. 
 

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 Hiline 52D series system is an open circuit solar water heater with its vitreous enamel lined solar 
storage tank installed on the roof directly coupled to the solar collectors. An open circuit system has a collector 
circuit which is directly connected to the potable water in the solar storage tank. 
 
The solar water heater uses the thermosiphon principle, without the 
need  for  a  pump,  circulator  or  sensors.  It  works  on  the  simple 
scientific fact that  hot  water rises.  The solar collectors absorb solar 
energy. The low-iron content solar glass allows more solar energy to 
pass through and be 

used to heat the collector’s absorber plate than 

conventional glass. 
 
As  the  water  in  the  solar  collector  gains  the  sun’s  heat  from  the 
absorber,  the  increase  in  temperature  causes  the  water  to  rise 
through  an  insulated  copper  pipe  into  the  solar  storage  tank.  This 
allows cooler water from the solar storage tank to flow into the solar 
collectors to be heated by the sun’s energy. This process continues 
while solar energy is available and until the water in the solar storage 
tank reaches a temperature of approximately 75°C. 
 
Automatic safety controls are fitted to the water heater to provide safe and efficient operation.
