ABOUT YOUR WATER HEATER
7
DOES THE WATER QUALITY AFFECT THE WATER HEATER?
The water heater is suitable for most public water supplies, however some
water qualities may have detrimental effects on the cylinder and fittings.
If you
are in a known harsh water area you must read page 46
. If you are not sure,
have your water quality checked against the conditions described on page 46.
HOW LONG WILL THE WATER HEATER LAST?
There are a number of factors that will affect the length of service the water
heater will provide. These include the water quality, the water pressure, the
water temperature (inlet and outlet) and the water usage pattern. However,
your Rheem water heater is supported by a comprehensive warranty
(refer to
page 48 ) .
ANODE PROTECTION
The anode(s) installed in your water heater will slowly dissipate whilst
protecting the cylinder. The life of the water heater cylinder may be extended
by arranging for an authorised person to inspect the anode(s) and replace if
required.
The suggested time after installation when the anode(s) should be inspected is:
Heavy Duty
7 years.
For softened water supplies or in areas of poor water quality, it is
recommended the anode(s) be inspected 3 years earlier than shown (refer to
“Water Supplies” on page 46).
