10 CFR 429.44 - Commercial water heating equipment. | US Law | LII / Legal Information Institute
CFR › Title 10 › Chapter II › Subchapter D › Part 429 › Subpart B › Section 429.44 10 CFR 429.44 - Commercial water heating equipment.
(a) For residential-duty commercial water heaters, all represented values must be determined in accordance with § 429.17.
Determination of Represented Value for All Types of Commercial Water Heaters Except Residential-Duty Commercial Water Heaters. Manufacturers must determine the represented value, which includes the certified rating, for each basic model of commercial water heating equipment except residential-duty commercial water heaters, either by testing, in conjunction with the applicable sampling provisions, or by applying an AEDM as set forth in § 429.70.
(1) The requirements of § 429.12 are applicable to commercial WH equipment; and
(2) Pursuant to § 429.12(b)(13), a certification report must include the following public equipment-specific information:
(iii) Commercial water heaters and hot water supply boilers with storage capacity greater than 140 gallons: The thermal efficiency in percent (%), whether the storage volume is greater than 140 gallons (Yes/No); whether the tank surface area is insulated with at least R-12.5 (Yes/No); whether a standing pilot light is used (Yes/No); for gas or oil-fired water heaters, whether the basic model has a fire damper or fan assisted combustion (Yes/No); and, if applicable, pursuant to 10 CFR 431.110, the maximum standby loss in British thermal units per hour (Btu/h) and measured storage volume in gallons (gal).
(ii) For any basic model rated with an AEDM, whether the manufacturer elects the witness test option for verification testing. (See § 429.70(c)(5)(iii) for options). However, the manufacturer may not select more than 10% of AEDM-rated basic models to be eligible for witness testing.
(4) Pursuant to § 429.12(b)(13), a certification report may include supplemental testing instructions in PDF format. If necessary to run a valid test, the equipment-specific, supplemental information must include any additional testing and testing set up instructions (e.g., whether a bypass loop was used for testing) for the basic model and all other information (e.g., operational codes or overrides for the control settings) necessary to operate the basic model under the required conditions specified by the relevant test procedure. A manufacturer may also include with a certification report other supplementary items in PDF format (e.g., manuals) for DOE consideration in performing testing under subpart C of this part.
(d) Alternative methods for determining efficiency or energy use for commercial WH equipment can be found in § 429.70 of this subpart.
