This final rule incorporates by reference the latest version of the industry testing standard for consumer water heaters and residential-duty commercial water heaters and adopts relevant portions of those standards into the Federal test procedure. In this final rule, the U.S. Department of Energy (DOE) is also expanding the scope of coverage of the test procedure to apply to certain consumer water heater designs (including circulating water heaters and low-temperature water heaters), adding definitions for certain specialty water heaters, updating test conditions and tolerance requirements to reduce burden, clarifying test set-up and installation methods, addressing the test conduct for products which can store water at temperatures above the delivery setpoint, establishing an effective volume calculation, and extending untested provisions to electric instantaneous water heaters.

The effective date of this rule is July 21, 2023. The final rule changes will be mandatory for consumer water heater testing starting December 18, 2023 and for residential-duty commercial water heater testing starting June 17, 2024. The incorporation by reference of certain material listed in this rule is approved by the Director of the Federal Register on July 21, 2023.
