On November 15, 2013 the U.S. Department of Energy (DOE) published a notice of proposed rulemaking regarding test procedures for residential water heaters and certain 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.
