SUBDIVISION DGas-Fired Instantaneous Water Heaters

Marginal note:Definitions

 The following definitions apply in this Subdivision.

gas-fired instantaneous water heater

gas-fired instantaneous water heater means a flow-activated water heater that uses natural gas or propane for fuel, that has a Vr that is less than or equal to 37.85 L (10 US gallons) and has an input rate to Vr ratio of not less than 309 W/L (4,000 Btu/h/US gallon). (chauffe-eau instantané au gaz)

maximum flow rate

maximum flow rate means, in respect of a gas-fired instantaneous water heater, the maximum litres per minute (gallons per minute) of hot water that can be supplied by the water heater while operating in a steady state and maintaining a nominal temperature rise of 37.3°C (67°F). (débit maximal)

10 C.F.R Appendix C

10 C.F.R Appendix C means Appendix C to the Subpart G, Part 431 of Title 10 to the United States Code of Federal Regulations, entitled Uniform Test Method for the Measurement of Thermal Efficiency and Standby Loss of Gas-Fired and Oil-Fired Instantaneous Water Heaters and Hot Water Supply Boilers (Other Than Storage-Type Instantaneous Water Heaters), as amended from time to time. (appendice C 10 C.F.R.)

  • SOR/2019-164, s. 40

Marginal note:Type

 For the purpose of these Regulations, a gas-fired instantaneous water heater is one of the following types:

  • (a) household, if it has an input rate of less than 58.56 kW (200,000 Btu/h), has a Vr of no greater than 7.6 L (2 US gallons) and is designed to provide hot water at a temperature no greater than 82°C (180°F); or

  • (b) commercial, if it is not described in paragraph (a).

  • SOR/2019-164, s. 40

Marginal note:Energy-using product

  •  (1) A gas-fired instantaneous water heater is prescribed as an energy-using product.

  • Marginal note:Limit

    (2) However, for the purposes of sections 4, 5 and 385, a gas-fired instantaneous water heater is not considered to be an energy-using product unless

    • (a) it is a household gas-fired instantaneous water heater that is manufactured on or after January 1, 2020; or

    • (b) it is a commercial gas-fired instantaneous water heater that is manufactured on or after July 1, 2023.

  • SOR/2019-164, s. 40

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 instantaneous water heaters described in column 1 that are manufactured during the period set out in column 4.

  • Marginal note:Testing standards

    (2) A gas-fired instantaneous 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 instantaneous water heater as defined in section 382.
