AvailableSuperseded
An Available Superseded Standard is one, which has been made available for a period of time although it has been formally superseded by another Standard. Its availability is maintained where it is referenced in legislation/regulations or in other Standards and its use should be restricted to where so referenced. No responsibility is taken by SAI Global as to the ongoing technical validity of such a Standard, the responsibility resting with the referencing authority.

Important note : Users cannot be edited or removed once added to your Multi user PDF.Sets out a method of evaluating the annual energy performance of water heaters using a combination of test results for component performance and a mathematical model to determine the standardized annual purchased energy use. The procedure is applicable to electric, gas and solar water heaters with integral boosting or preheating into a conventional storage or instantaneous water heater and to heat pump water heaters. For solar and heat pump water heaters, displaced purchased energy relative to reference water heaters is also calculated.

This Standard sets out a method of evaluating the annual energy performance of water heaters using a combination of test results for component performance and a mathematical model to determine the standardized annual purchased energy use. The procedure is applicable to electric, gas and solar water heaters with integral boosting or preheating into a conventional storage or instantaneous water heater and to heat pump water heaters. For solar and heat pump water heaters, displaced purchased energy relative to reference water heaters is also calculated. Solar and solar boosted heat pump water heater types not covered in the application of this Standard can be tested under AS 2984 to obtain an annual performance assessment.There are no product design or operation requirements in this Standard. System operating parameters specified in this Standard are only for the purpose of performance modelling.
