Electric and Gas Storage Water Heaters
WATER SUPPLY & CONNECTION
Water Supply:
Your water heater has been
manufactured to suit the water
conditions of most Australian
metropolitan supplies.
Please note certain water supplies
can have a detrimental effect on your
water heater and its life expectancy. If
you are unsure about the water supply
you can obtain information from your
local water supply authority.
Your water heater is designed for use in
areas where the Total Dissolved Solids
(TDS) content of the water supply is
less than 2500 mg/L. The Tank Failure
Warranty does not apply in areas where
the TDS exceeds 2500 mg/L.
In areas where the TDS exceeds
600mg/L, it is possible the magnesium
alloy anode (supplied in standard water
heaters) may become over-reactive.
To alleviate this, a hard-water model
is recommended or the magnesium
alloy anode should be replaced with an
aluminium alloy anode. Aluminium alloy
anodes are available from your local
Reece branch.
Water can also be very corrosive, the
measure of this is the saturation index.
If the water saturation index is greater
than 0.40, an expansion control valve
should be fitted. If the index is greater
than 0.80, the electrical heating element
(fitted to electric storage water heaters)
should be replaced with a low power
density Incoloy heating element.
Please consult Customer Service on
1300 412 612 for advice if required.
Hot Water Connection:
It is recommended that all hot water
pipes are insulated. Hot water pipes
installed outdoors should be insulated
with UV stabilised insulation.
Cold Water Connection:
An approved isolating valve,
non-return valve, line strainer (optional
but recommended) and union must be
fitted between the water supply main
and the water heater.
Water Supply Pressure:
Your water heater is designed for
direct connection to water supply
pressures of up to:
Electric Storage Water Heaters:
- 800 kPa.
Gas Storage Water Heaters:
- 1,120 kPa.
Where the mains pressure can exceed
or fluctuate beyond this pressure, a
pressure reducing valve must be fitted
in the cold water inlet supply.
Note for New Zealand, South Australia
and Western Australia:
It is a requirement in these locations
that an expansion control valve be
fitted on the cold water supply line
between the non-return valve and the
water heater.
