EXPANSION CONTROL VALVE RUNNING 
If an expansion control valve is fitted in the cold water line to the water heater 

temperature pressure relief valve on the water heater. The benefit is that 
energy is conserved as the discharged water is cooler. 
 
HIGH ELECTRICITY BILLS 
Should you at any time, feel your electricity account is too high, we suggest you 
check the following points: 

• 

Is the relief valve running 
excessively? (Refer to 

 on page 13). 

 
 

 

• 

Is one outlet (especially the 
shower) using more hot water than 
you think? (Refer to 

 on page 12). 

• 

Is there a leaking hot water pipe, 
dripping hot water tap, etc? Even a 
small leak will waste a surprising 
quantity of hot water and electricity. 
Replace faulty tap washers, and 
have your plumber rectify any 
leaking pipe work. 

• 

Consider recent changes to your hot water usage pattern and check if there 
has been any increase in tariffs since your previous account. 

 
ELECTRICITY TARIFFS 
The electricity tariff to which your water heater is connected will determine the 
overall operating cost of the system. It is important you are aware of this tariff, 
i.e. 

Off-Peak (overnight) or time controlled supply, Extended Off-Peak 

(overnight and day) or Extended time controlled supply, Domestic / Continuous. 
For types of tariffs, refer to 

 on page 8 and 

 on page 9. 

 
IF YOU HAVE CHECKED ALL THE FOREGOING AND STILL BELIEVE YOU 
NEED ASSISTANCE, CALL YOUR NEAREST RHEEM SERVICE 
DEPARTMENT OR ACCREDITED SERVICE AGENT.
