Energy labels can be found on gas water heaters (both storage and instantaneous) (AS4552). Gas energy labels are similar in format to those found on electrical appliances, except they are blue in colour and with annual energy shown in MJ. The gas labelling program is currently an industry voluntary scheme that was once managed by the Australian Gas Association (AGA). A review of the scheme is under way by the Gas Industry and Governments. Note that the AGA is no longer responsible for publishing standards. This organisation now provides accredited product certification services with respect to the gas, electrical and plumbing sectors within Australia. More information about product certification for gas products is available at:
