Marginal note:Definitions
315 The following definitions apply in this Subdivision.
- CGA P.2
CGA P.2 means the CGA standard CGA P.2-1991 entitled Testing Method for Measuring Annual Fuel Utilization Efficiencies of Residential Furnaces and Boilers. (CGA P.2)
- CSA P.2
CSA P.2[Repealed, SOR/2019-164, s. 14]
- gas boiler
gas boiler means a boiler that uses exclusively propane or natural gas, is intended for application in a low pressure steam, or hot water, central heating system and has an input rate of not more than 2 930.71 kW (10,000,000 Btu/h). (chaudière à gaz)
Marginal note:Type
315.1 For the purpose of these Regulations, a gas boiler is one of the following types:
(a) household, if it has an input rate of less than 87.92 kW (300,000 Btu/h); or
(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).
Marginal note:Energy-using product
316 (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
(b) for the purposes of sections 5 and 317 unless
(i) it is a household gas boiler that is manufactured on or after December 31, 1998, or
(ii) it is a commercial gas boiler that is manufactured on or after January 1, 2025.
Marginal note:Energy efficiency standards — household
317 (1) The energy efficiency standards set out in column 3 of Table 1 to this section apply to household gas boilers described in column 1 that are manufactured during the periods set out in column 4.
Marginal note:Testing standard — household
(2) A household gas boiler 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 1 that are applicable to a gas boiler as defined in section 315.
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 gas boilers described in column 1 that are manufactured on or after January 1, 2025.
Marginal note:Testing standard — commercial
(4) A commercial gas boiler complies with the energy efficiency standard if it meets that standard when tested in accordance with testing procedures established by 10 C.F.R. Appendix A that are applicable to a gas boiler as defined in section 315.
