ABOUT YOUR WATER HEATER

HOW HOT SHOULD THE WATER BE?
The solar water heater will deliver water at temperatures up to 70°C to
80°C for a Vulcan solar direct or indirect pumped system and possibly
higher for some other models of solar water heaters.
During periods of low solar energy gain, the in-series gas booster will boost
the water temperature automatically to its preset outlet temperature setting.
The factory preset outlet temperature setting is 60°C.
Note:
The preset outlet temperature setting of this water heater cannot be
adjusted by the householder. The setting can only be adjusted by the
installer, Rheem Service or their nearest Accredited Service Agent.
Note:
AS 3498 requires that a water heater provides the means to inhibit
the growth of Legionella bacteria in potable water. When this water heater
is used as an in-series booster for a solar water heater it can satisfy this
AS 3498 requirement provided it is energised, the booster preset outlet
temperature setting is 70°C or higher, and that a remote temperature
controller is not used.
Warning:
Temperature controllers
must not
be fitted to this water heater as part of a solar water heater
system because water at a temperature much higher than the controller setting can be delivered.
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
This water heater can deliver water at temperatures which can cause scalding. Check the water temperature
before use, such as when entering a shower or filling a bath or basin, to ensure it is suitable for the
application and will not cause scald injury.
We recommend and it may be required by regulations that an approved temperature limiting device be fitted
into the hot water piping to the bathroom and ensuite when this water heater is installed. This will keep the
water temperature below 50°C at the bathroom and ensuite. The risk of scald injury will be reduced and still
allow hotter water to the kitchen and laundry.
