A RheemPlus water 
heater will not deliver 
temperatures exceeding 
50

°C, in accordance with 

AS 

3498. There is no 

statutory requirement to 
fit a temperature limiting 
device if this water heater 
is installed in other than 
an early childhood centre, 
school, nursing home or a 
facility for young, aged, 
sick or disabled people. 
 
CIRCULATED HOT WATER FLOW AND RETURN SYSTEM 
A RheemPlus water heater cannot be installed as part of a circulated hot water 
flow and return system in a building. 
 
If a Rheem water heater is to be installed as part of a circulated hot water flow 
and return system, a storage water heater able to provide a hot water outlet 
temperature of at least 60

°C must be used. Note: The thermostat must always 

be set to at least 60

°C. Refer to the 

diagram on page 

18. 

 
Temperature Limiting Device 
A temperature limiting device cannot be installed in circulated hot water flow 
and return pipe work. The tempered water from a temperature limiting device 
cannot be circulated. Where a circulated hot water flow and return system is 
required in a building, a temperature limiting device can only be installed on a 
dead leg, branching off the circulated hot water flow and return pipe. 
 
If circulated tempered water were to be returned back to the water heater, 
depending on the location of the return line connection on the water supply line 
to the water heater, then either: 
 

• 

water will be supplied to the cold water inlet of the temperature limiting 
device at a temperature exceeding the maximum recommended water 
supply temperature, or 

• 

when the hot taps are closed no water will be supplied to the cold water 
inlet of the temperature limiting device whilst hot water will continue to be 
supplied to the hot water inlet of the temperature limiting device.
