TITLE:  Energy Efficiency Program: Test Procedur es for Residential Water Heaters, Direct Heating 
Equipment, and Pool Heaters  AGENCY:  Office of Energy Efficiency and Renewable Energy, Department of Energy 
 
ACTION:  Final rule 
 SUMMARY:  Where appropriate, the U.S. Depart ment of Energy (DOE) is amending its test 
procedures for residential water heaters, direct h eating equipment (DHE), 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 has concluded that such amendments are 
necessary for direct heating equipment and pool heaters, but test procedure amendments are not necessary for residential water heat ers, because the existing test pro cedures for those products already 
address standby mode and off mode energy use. Th ese test procedure amendments are primarily based 
upon provisions of the latest version of the Intern ational Electrotechnical Commission (IEC) Standard 
62301 (Second Edition 2011-01), "Household electrica l appliances--Measurement of standby power", 
which is incorporated by reference. For direct heati ng equipment and pool heaters, this final rule also 
adds new calculations to determ ine the annual energy consumptio n associated with product operation 
in standby mode and off mode, and it modifies the existing energy consumpti on equations to integrate 
standby mode and off mode energy consumption into the calculation of overall annual energy 
consumption of these products. For pool heaters onl y, the standby mode and off mode energy 
consumption is integrated into the efficiency metric. This rulemaking also adopts a number of 
definitions for key terms, as well as clarifies the rounding guidance and sampling provisions for the 
new measurement of standby mode and off mode.  DATES:  This rule is effective 16 January 2013.  The incorporation by reference of certain 
publications listed in this rule is approved by th e Director of the Federal Register on 16 January 2013.

  The compliance date for any representations relating to standby mode and off mode of residential 
direct heating equipment and pool heaters is 17  June 2013; on and after this date, any such 
representations must be based upon results generate d under these test procedures and sampling plans. 
For purposes of compliance with energy conservati on standards, these test procedure amendments 
related to standby mode and off m ode are not required at this time, but their use will be required upon 
the compliance date of the next standards final rule which will address standby mode and off mode.
