Please contact your electricity provider to confirm the times when you pay off-peak, shoulder and peak tariffs for your electricity. Your water heater will be connected to an appropriate tariff \(timed control\), depending on its capacity, to ensure you have sufficient hot water for your needs. Twin element water heater models have the added benefit of using off peak tariffs to save money whilst providing an extra boost should it be needed. Please see the Owner's Guide for your Storage Water Heater model.

It is normal and desirable the temperature pressure relief valve or expansion control valve \(if fitted\) allows a quantity of water to escape during the heating cycle. This quantity should be equal to approximately 1/50 of the hot water used, as water expands by this volume when heated. However, if it discharges more than a bucket full of water in 24 hours, there may be another problem. Please see the Owner’s Guide for you Storage Water Heater model or further information.

The flow of hot water is not adequate to keep the water heater operating. This can be caused by flow restrictors and water saving low flow taps. You’ll need to have a plumber increase your hot water flow rate to a minimum of two to three litres per minute.

Lowering the temperatures of your stored hot water will result in a greater level of hot water consumption. Therefore, it is unlikely to significantly reduce your gas or electricity consumption. Also, in order to meet the requirements of the Plumbing Code and for showers to operate correctly, it’s necessary to store your hot water at a minimum of 60?C.

The water temperature may be lower than usual due to heavy hot water usage. Also, this problem could be due to faulty tempering valve that is excessively cooling your hot water. Your local approved Plumber can test your system and replace the valve if necessary. To find your local Rheem Plumber, contact us or call Rheem on 1300 556 036.
Do you have a solar water heater? Check that the booster is being used as per the installation instructions for your model. If you have a timer installed, you will need to ensure that sufficient time is allowed to heat enough water to meet your household’s hot water needs
If you have a 50°C temperature limited water heater, then hot water to your whole house will be limited to 50°C

For showers to operate correctly, it’s necessary to store your hot water at a minimum of 60°C.
If your water heater is fitted with a temperature limiting valve and the water is hotter than it should be, please call Rheem on 1300 556 036.
If your hot water is hotter than it should be and you don’t have a temperature limiting valve installed, then you could:

• Have the thermostat on your water heater adjusted downward (with a gas storage water heater you can do this yourself). Please note that gas storage must be set no lower than 60°C and a gas continuous flow booster for a solar system must be set no lower than 70°C
