Things that you should know about the Rheem Running Cost Estimator


The Rheem Running Cost 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 AS4552, 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 operation. Accordingly, the estimator 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 AS4552 and average fuel tariffs used in the calculator.

Your post code 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 2015 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.
