Energy Efficiency Regulations, 2016

Version of section 380 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 oil-fired water heaters described in column 1 that are manufactured during the period set out in column 4.

  • Marginal note:Testing standard — household

    (2) An oil-fired water heater 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 that are applicable to a oil-fired water heater as defined in section 378.

  • 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 oil-fired water heaters described in column 1 that are manufactured on or after January 1, 2020.

  • Marginal note:Testing standard — commercial

    (4) A commercial oil-fired water heater 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 2 that are applicable to an oil-fired water heater as defined in section 378.
