Previous Version

Marginal note:Type

378.1 For the purpose of these Regulations, an oil-fired water heater is one of the following types:

  • (a) household, if it has an input rate of less than or equal to 30.5 kW (105,000 Btu/h); or

  • (b) commercial, if it is has an input rate of greater than 30.5 kW (105,000 Btu/h).

Marginal note:Energy-using product

  • 379 (1) An oil-fired water heater is prescribed as an energy-using product.

  • Marginal note:Limits

    (2) However, for the purposes of sections 4, 5 and 380, an oil-fired water heater is not considered to be an energy-using product unless

    • (a) it is a household oil-fired water heater that is manufactured on or after February 3, 1995; or

    • (b) it is a commercial oil-fired water heater that is manufactured on or after January 1, 2020.

Marginal note:Energy efficiency standards — household

  • 380 (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.
