Water is stored in a vitreous enamel lined steel cylinder and
heated by a gas burner located under the cylinder. The heat
produced by the burner is transferred to the water through the
base of the cylinder and through the wall of a flue pipe which
passes through the centre of the cylinder. A flue baffle in this
flue ensures the efficiency of the water heater is correct. The
gas supply to the burner is controlled by the thermostat so the
water is heated to a constant temperature.
Automatic safety controls are fitted to the water heater to
provide safe and efficient operation.
HOW HOT SHOULD THE WATER BE?
The water heater features a user adjustable
thermostat, which allows you to choose the most
suitable temperature for your hot water needs.
Refer to "Temperature Adjustment"
A RheemPlus water heater is temperature limited to
deliver water not exceeding 50°C.
To meet the requirements of the National Plumbing
Standard the temperature of the stored water must
not be below 60°C.
Note: AS 3498 requires that a water heater
provides the means to inhibit the growth of
Legionella bacteria in potable water. This water
heater can satisfy this AS 3498 requirement
provided it is operating and the thermostat setting is
60°C or higher, including when it is used as an in-
series booster water heater for a solar water heater.
