International Review of Minimum Energy Performance Standards for Electric Resistance Storage Water Heaters


The aim of this document is to provide more up-to-date information on the status of overseas MEPS levels for electric storage water heaters and to provide a more rigorous modelling approach to the comparison of overseas MEPS levels with the equivalent standing heat loss level in AS1056. The report is intended for use by government when considering the MEPS levels in force overseas as models for implementation in the Australian context.

Electric resistance storage water heaters covered by AS1056 are the focus of this review, including size ranges 25 to 630 L rated hot water delivery capacity. This report does not consider heat exchange water heaters.

A draft of this report was provided in July 2000. The water heater MEPS rules in the USA were released in January 2001 and these have been incorporated in this final report, along with the revised options for consideration.

Notes: This report expands and updates a previous submission to the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which was prepared by Harrington, L. in December 1998.
