(C) Multi-input electric storage water heater The term multi-input electric storage water heater (i) is not a heat pump type unit described in subparagraph (A)(iii); and (ii) is designed, marketed, or shipped from the manufacturer with a capability of operating or being configured to operate at inputs greater than, equal to, or below 12 kilowatts. (D) Solar thermal-assisted electric storage unit The term solar thermal-assisted electric storage unit (i) has an input of 12 kilowatts or less; (ii) has at least 2 dedicated ports in addition to the ports used for introduction and delivery of potable water for the supply and return of water or a heat transfer fluid heated externally by solar panels; (iii) does not have electric resistance heating elements located in the lower half of the storage tank; (iv) has the temperature sensing device that controls the auxiliary electric heat source located in the upper half of the storage tank; and (v) has a ratio of less than 0.70 for the proportion that the certified first hour rating bears to the nominal volume of the storage tank. . (b) Standards for water heaters Section 325(e) of the Energy Policy and Conservation Act ( 42 U.S.C. 6295(e) (7) Exempted water heaters (A) Definition of exempted water heater In this paragraph, the term exempted water heater (B) Monitoring of shipments (i) Submission of data Not later than 90 days after the date of enactment of this paragraph, and not later than May 1 of each year thereafter, the Secretary shall require each manufacturer of water heaters to report to the Secretary the quantity of exempted water heaters, in each category of exempted water heaters, that the manufacturer shipped in the preceding calendar year. (ii) Confidentiality requirements The Secretary shall treat shipment data reported by manufacturers under clause (i) as confidential business information subject to appropriate confidential data safeguards. (iii) Publication (I) Baseline shipment data Not later than 120 days after the date of enactment of this paragraph, the Secretary shall publish an analysis of the data collected under clause (i) for public comment, subject to applicable confidentiality safeguards, which shall serve as the baseline data for the analysis described in subclause (II)(bb). (II) Percentage growth from baseline Not later than June 1 of each year after the year in which the Secretary publishes data under subclause (I), the Secretary shall publish— (aa) an analysis of the data collected under clause (i) for public comment, subject to applicable confidentiality safeguards; (bb) the percentage growth in the number of shipments within each category of exempted water heater relative to the baseline data described in subclause (I); and (cc) the determination of the Secretary as to whether the number of shipments for any category of exempted water heater have increased by more than 25 percent compared to the baseline data for that category. (C) Inclusion of exempted water heaters (i) In general The Secretary shall, by regulation, revise the definition of water heater under section 321(27) to include an exempted water heater under subparagraph (A) of that section if the Secretary makes an affirmative determination under subparagraph (B)(iii)(II)(cc) for that category of exempted water heater. (ii) Energy conservation standards Any category of exempted water heater included in the definition of water heater under clause (i) shall be required to meet the energy conservation standards applicable to an electric or gas storage type water heater under this part. (iii) Effective date For any category of exempted water heater, the Secretary shall carry out clause (i), and require compliance under clause (ii), not later than 1 year after the date on which the Secretary makes the affirmative determination described in clause (i) for that category.

(9) Technology-neutral electric storage water heater standards Notwithstanding any other provision of this Act, the Secretary may not create separate product classes for heat pump water heaters and other electric storage water heaters. . (c) Definition of commercial water heater Section 340 of the Energy Policy and Conservation Act ( 42 U.S.C. 6311 (12) (A) Storage water heater (i) In general The term storage water heater (I) heats and stores water within an appliance at a thermostatically controlled temperature for delivery on demand; and (II) is not a water heater described in section 321(27)(A). (ii) Exclusion The term storage water heater (B) Instantaneous water heater The term instantaneous water heater (i) has an input rating of at least 4,000 Btu per hour per gallon of stored water; and (ii) is not a water heater described in section 321(27)(A). (C) Unfired hot water storage tank The term unfired hot water storage tank . (d) Labeling requirements Section 344 of the Energy Policy and Conservation Act ( 42 U.S.C. 6315 (l) Labels for certain commercial water heaters (1) In general Notwithstanding any other provision of this section, water heaters described in section 321(27)(B) shall be required to bear a permanent label, applied at the point of manufacture, that, subject to paragraph (3), satisfies the requirements described in paragraph (2).

This model is not certified by the U.S. Department of Energy as a residential water heater. This model does not have a certified First Hour or UEF rating. (3) Revision upon petition On receipt of a petition by an interested party, the Secretary may conduct a rulemaking to revise the scope and requirements of the label required under paragraph (1). . (e) Effective date This section and the amendments made by this section shall take effect 180 days after the date of enactment of this Act.

Summary: This bill modifies the definition of water heater, and otherwise revises energy conservation standards and sets forth labeling requirements for water heaters.
