Residential Water Heater and Certain Commercial Water Heater Test Procedures

October 29th 2013

On October 29, 2013 the U.S. Department of Energy (DOE) issued a pre-publication Federal Register 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.
