external storage heaters with a nominal gas consumption of less than 50 MJ/h and storage capacity of over 30 litres internal and external instant gas water heaters with a nominal gas consumption of less than 250 MJ/h and a heat output of less than 13.1 kW (equivalent to a delivery rate of 7.5 L/min raised through 25C)

The following products are exempt from MEPS: Water heaters that use electric resistive heating to provide less than 50% of the energy supplied in a typical year (eg heat pump and solar water heaters) when simulated to AS 4234 under Climate Zone 3 with an energy delivery of 22.5 MJ/day for an electric boosting element and energisation profile specified by the manufacturer. Water heaters that are not intended for electric power grid connection (eg for use in vehicles and marine applications).

Class 1 Computer monitors with a diagonal screen size less than 76 cm (30 inches) and a screen resolution less than or equal to 1.1 MegaPixels. Class 2 Computer monitors with a diagonal screen size less than 76 cm (30 inches) and a screen resolution greater than 1.1 MegaPixels. Class 3 Computer monitors with a diagonal screen size equal to or greater than 76 cm (30 inches) and equal to or less than 152 cm (60 inches)." "

The energy efficiency index, or EEI, of a refrigerated cabinet that is covered by this instrument is calculated in accordance with the following formula:

where:

AEC is the refrigerated cabinet’s annual energy consumption, in kWh per year, and is calculated in accordance with section 26.

RAEC is the refrigerated cabinet’s reference annual energy consumption, in kWh per year, and is calculated in accordance with section 26.

Note: For refrigerated cabinets that are covered by this instrument, other than low sales volume and/or oversize RDCs and low sales volume RSCs, the reference annual energy consumption is equal to the standard annual energy consumption, which represents the energy consumption of a standard cabinet of the relevant type.

For low sales volume and/or oversize RDCs and low sales volume RSCs, the reference annual energy consumption is equal to the base annual energy consumption, which reflects the energy consumption of a reference low‑efficiency version of a cabinet of the relevant type.
