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

摘要

The U.S. Department of Energy (DOE) proposes to revise its test procedure for residential water heaters and certain commercial water heaters established under the Energy Policy and Conservation Act. This rulemaking will fulfill DOE's statutory obligation for residential and certain commercial water heaters to review its test procedure for covered products and equipment at least once every seven years. In addition, this rulemaking will satisfy DOE's statutory obligation to develop a uniform efficiency descriptor for residential and commercial water heaters. The proposed test method would apply the same efficiency descriptor to all residential and certain commercial water heaters, and it would extend coverage to eliminate certain gaps in the current residential test procedure, update the simulated-use-test draw pattern, and update the water delivery temperature requirement. DOE is also announcing a public meeting to discuss and receive comments on issues presented in this test procedure rulemaking.
