SEC. 2. UNIFORM EFFICIENCY DESCRIPTOR FOR COVERED WATER HEATERS.

    Section 325(e) of the Energy Policy and Conservation Act (42 U.S.C. 
6295(e)) is amended by adding at the end the following:
            ``(5) Uniform efficiency descriptor for covered water 
        heaters.--

                180 days after the date of enactment of this paragraph, 
                the Secretary shall publish a final rule that 
                establishes a uniform efficiency descriptor and 
                accompanying test methods for covered water heaters.

                        efficiency descriptor established by the final 
                        rule.
