  •  (1) A heat-recovery ventilator is prescribed as an energy-using product.

  • Marginal note:Limit

    (2) However, for the purposes of sections 4 and 5, a heat-recovery ventilator is not considered to be an energy-using product unless it is manufactured on or after January 1, 2020.

  • SOR/2019-164, s. 12

Marginal note:Information

 For the purpose of subsection 5(1) of the Act, the following information must be collected in accordance with CSA C439-18 and be provided to the Minister in respect of a heat-recovery ventilator:

  • (a) its maximum rated airflow at 0°C;

  • (b) its sensible heat recovery efficiency at 0°C and the associated net supply airflow, expressed in L/s, and electrical power consumption, expressed in watts; and

  • (c) unless the unit is marked for use only where the outdoor design temperature is greater than or equal to -10°C, its sensible heat recovery efficiency at -25°C and the associated net supply airflow, expressed in L/s.

Interpretation

Marginal note:Definitions

 The following definitions apply in this Division.

ASHRAE 103

ASHRAE 103 means the ANSI/ASHRAE standard 103-2007 entitled Method of Testing for Annual Fuel Utilization Efficiency of Residential Central Furnaces and Boilers. (ASHRAE 103)

automatic water temperature adjustment device

automatic water temperature adjustment device means a device that

  • (a) adjusts the temperature of the water supplied by a boiler to ensure that an incremental change in inferred heat load produces a corresponding incremental change in the temperature of the water supplied or, if the boiler fires at a single input rate, automatically allows the burner or heating element to fire only when the device has determined that the inferred heat load cannot be met by the residual heat of the water in the system; and

  • (b) when there is no inferred heat load, limits the water temperature in the boiler to not more than 60°C. (dispositif automatique de réglage de la température de l’eau)

CSA P.2

CSA P.2 means the CSA standard CAN/CSA-P.2-13 entitled Testing Method for Measuring the Annual Fuel Utilization Efficiency of Residential Gas-Fired or Oil-Fired Furnaces and Boilers. (CSA P.2)

10 C.F.R. Appendix A

10 C.F.R. Appendix A means Appendix A to Subpart E, Part 431 of Title 10 to the United States Code of Federal Regulations, entitled Uniform Test Method for the Measurement of Thermal Efficiency and Combustion Efficiency of Commercial Packaged Boilers, as amended from time to time. (appendice A 10 C.F.R.)

  • (b) commercial, if it is has an input rate of greater than or equal to 87.92 kW (300,000 Btu/h) but not more than 2 930.71 kW (10,000,000 Btu/h).

  • SOR/2019-164, s. 15

Marginal note:Energy-using product

  •  (1) A gas boiler is prescribed as an energy-using product.

  • Marginal note:Limits

    (2) However, a gas boiler is not considered to be an energy-using product

    • (a) for the purpose of section 4 unless

      • (i) it is a household gas boiler that is manufactured on or after June 30, 1999, or

      • (ii) it is a commercial gas boiler that is manufactured on or after January 1, 2025; and
