SUBDIVISION BGas-Fired Storage Water Heaters

Marginal note:Definitions

 The following definitions apply in this Subdivision.

CSA P.3-04

CSA P.3-04 means the CSA standard CAN/CSA-P.3-04 entitled Testing Method for Measuring Energy Consumption and Determining Efficiencies of Gas-Fired Storage Water Heaters. (CSA P.3-04)

gas-fired storage water heater

gas-fired storage water heater means a stationary gas-heated water container that uses propane or natural gas for fuel and has a Vr of at least 76 L (20 US gallons). (chauffe-eau à réservoir alimenté au gaz)

replacement unit

replacement unit means a commercial gas-fired storage water heater that is marked for replacement installations only. (unité de remplacement)

  • SOR/2019-164, s. 30

Marginal note:Type

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

  • (a) household, if it has an input rate of less than or equal to 21.97 kW (75,000 Btu/h); or

  • (b) commercial, if it is has an input rate of greater than 21.97 kW (75,000 Btu/h).

  • SOR/2019-164, s. 31

Marginal note:Energy-using product

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

  • Marginal note:Limits

    (2) However, for the purposes of sections 4, 5 and 376, a gas-fired storage water heater is not considered to be an energy-using product unless

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