Please see the Owner Guide for your Storage Water Heater model and our gas relighting videos.

Check out our Troubleshooting Guide for answers to some of the most common troubleshooting questions.

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

Running Cost Estimator Disclaimer as at 23/10/2017

Things that you should know about the Rheem Running Cost Estimator

The estimator is provided as a guide only to help you compare estimated running costs between various water heater types.

The estimator is based on Australian Standard AS5263, which relies on certain assumptions, such as an average daily load of 200L and 19 tap turns. Your situation and usage may be different to these assumptions, so the estimator may not match your actual daily loads and pattern of use.

Accordingly, the estimator cannot and does not purport to provide an accurate assessment of your yearly hot water energy bill. It does, however, allow a reasonable comparison between various water heater types based on Australian Standard AS5263 and average fuel tariffs used in the estimator.

Your state has been used to determine the temperature rise required to heat water from cold to a temperature of 65C, the applicable charge for the tariff type selected and the amount of solar savings.

Solar savings are based on Australian Government approved modelling for the type of solar water heater selected and the booster type. All electric boosted solar water heaters are modelled with a continuous tariff, but may be suitable for use on other tariff types depending on the model selected, your climate zone and the amount and usage pattern of hot water use.

Tariffs are current as at 1st July 2017 and represent an average price for the fuel type for the capital city in the state or territory, including GST.

Fixed charges, system access charges, delivery fees and any other fees and charges, including special rates and discounts are excluded from the estimator.

Energy consumption figures used are for a typical water heater within a category and do not reflect a specific model. Actual energy use may vary.

Heat Pump and solar water heaters may be suitable for Off Peak/Shoulder Rate tariffs depending on the type of water heater selected and the location. You should consult with your energy provider or installer before making any decision.
