Energy Efficiency Regulations, 2016

Version of section 376 from 2018-10-31 to 2019-12-11:


Marginal note:Energy efficiency standards

  •  (1) The energy efficiency standards set out in column 3 of the table to this section apply to gas-fired storage water heaters described in column 1 that are manufactured during the periods set out in column 4.

  • Marginal note:Testing standard

    (2) A gas-fired storage 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 gas-fired storage water heater as defined in section 374.
