Energy Conservation Program for Consumer Products: Test Procedures for Residential Water Heaters, Direct Heating Equipment, and Pool Heaters (Standby Mode and Off Mode)

On August 30, 2010, the U.S. Department of Energy (DOE) published a notice of proposed rulemaking (NOPR) in which DOE proposed to amend, where appropriate, its test procedures for residential water heaters, direct heating equipment, and pool heaters to include provisions for measuring standby mode and off mode energy consumption, as required by the Energy Independence and Security Act of 2007 (EISA 2007). (DOE notes that the test procedure and metric for residential water heaters currently address and incorporate standby mode and off mode energy consumption, so DOE has tentatively concluded that no related amendments are required for those products.). These proposed test procedure amendments are primarily based on provisions of the International Electrotechnical Commission (IEC) Standard 62301, "Household electrical appliances--Measurement of standby power," that DOE would incorporate by reference into its regulations. The NOPR relied upon IEC Standard 62301 (First Edition 2005-06), which was the most current version at the time. However, the IEC recently adopted a new version of its standard which includes a number of methodological changes designed to increase accuracy while redu
