Energy Conservation Program for Consumer Products and Certain Commercial and Industrial Equipment: Test Procedures for Consumer and Commercial Water Heaters

On April 14, 2015, the U.S. Department of Energy (DOE) published in the Federal Register a notice of proposed rulemaking (NOPR) that proposes mathematical conversion factors for converting from the current efficiency metrics (i.e., energy factor for residential water heaters, and thermal efficiency and standby loss for commercial water heaters) to the uniform efficiency descriptor (i.e., uniform energy factor metric). The comment period for the NOPR pertaining to the test procedures for water heaters was scheduled to end May 14, 2015. After receiving a request for additional time to comment for stakeholders, DOE is reopening the comment period for the NOPR for the Conversion Factor for Test Procedures for Consumer and Certain Commercial Water Heaters to June 15, 2015. Additionally, at the request of stakeholders, DOE is announcing a public meeting to discuss the conversion factors for consumer and commercial water heaters.
