Energy Efficiency Regulations, 2016

Version of section 317 from 2023-06-21 to 2024-02-06:


Marginal note:Energy efficiency standards — household

  •  (1) The energy efficiency standards set out in column 3 of Table 1 to this section apply to household gas boilers described in column 1 that are manufactured during the periods set out in column 4.

  • Marginal note:Testing standard — household

    (2) A household gas boiler complies with the energy efficiency standard if it meets that standard when tested in accordance with testing procedures established by the standard set out in column 2 of Table 1 that are applicable to a gas boiler as defined in section 315.

  • Marginal note:Energy efficiency standards — commercial

    (3) The energy efficiency standards set out in column 2 of Table 2 to this section apply to commercial gas boilers described in column 1 that are manufactured on or after January 1, 2025.

  • Marginal note:Testing standard — commercial

    (4) A commercial gas boiler complies with the energy efficiency standard if it meets that standard when tested in accordance with testing procedures established by 10 C.F.R. Appendix A that are applicable to a gas boiler as defined in section 315.
