Energy Conservation Program for Consumer Products: Test Procedures for Residential Furnaces and Boilers (Standby Mode and Off Mode)

The U.S. Department of Energy (DOE) is amending its test procedures for residential furnaces and boilers 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). These test procedure amendments are primarily based on and incorporate by reference provisions of the International Electrotechnical Commission (IEC) Standard 62301, "Household electrical appliances--Measurement of standby power." This final rule adds new calculations to determine the annual energy consumption associated with standby mode and off mode measured power, and it modifies the existing energy consumption equations to integrate standby mode and off mode energy consumption into the calculation of overall annual energy consumption of these products. This final rule also adopts a number of definitions for key terms.
