SAVE A SERVICE CALL
This may also occur on a water heater without an over temperature protection (OTP) system during
periods of increased solar gain in the hotter months and particularly if there is a reduced level of hot water
consumption. It is most likely to happen during the daytime.
The temperature pressure relief valve will discharge water if the water temperature increases to a very
high level under these conditions. This higher temperature water is replaced with incoming cold water to
reduce the energy level inside of the tank. The valve will close when cooler water surrounds the
temperature probe of the valve. As this is a function of the temperature pressure relief valve under these
conditions, it is not necessary to make a service call, however you may consider having an over
temperature protection (OTP) system installed.
COLLECTOR GLASS
The Rheem warranty DOES NOT cover breakage of solar collector glass. Check your household insurance
policy covers collector glass breakage.
Warning: No attempt should be made to remove or replace broken collector glass.
The collector glass is not offered as a replacement part. Should the solar collector require replacement, contact
Rheem Service or their nearest Accredited Service Agent.
HIGHER THAN EXPECTED ELECTRICITY BILLS
With the installation of your new solar hot water system, maximum electrical energy savings can be achieved
with careful planning of hot water usage. Should you at any time feel your electricity bill is higher than expected,
we suggest you check the following points:
•
Is the relief valve running excessively?
"Temperature Pressure Relief Valve or Expansion Control Valve Running"
Refer to
•
Is one outlet (especially the shower) using more hot water than you
think?
"Not Enough Hot Water"
Refer to
•
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
energy. Replace faulty tap washers, and have your plumber rectify
any leaking pipe work.
•
Are you using the booster heating unit properly?
"Booster Control"
Refer to
•
Has there been an increase in hot water usage?
An increase in hot water usage may result in an increase in booster operation.
•
Has your water heating tariff rate been increased by your electricity retailer since your previous bill?
ELECTRICITY TARIFFS
The electricity tariff to which your solar water heater is connected will play an important role in the overall
effectiveness of the system. It is important you are aware of this tariff to enable you to take full advantage of
the boosting period, i.e. Domestic / Continuous or Time of Use, Extended Off-Peak (overnight and day) or
extended time controlled, or Off-Peak (overnight) or time controlled.
The electricity tariff will impact on the operating costs of the system. Time controlled tariffs are generally
cheaper than a continuous supply tariff and result in lower running costs.
