Energy Efficiency Regulations

Regulatory definition

Gas boiler, 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 less than 87.92 kW (300 000 Btu/h)

Compliance date

Manufactured on or after September 1, 2010 and before January 15, 2021 and intended for low pressure steam systems.

For models manufactured prior, refer to the Regulations

Compliant product models

Testing standard

CAN/CSA-P.2-13

Energy efficiency regulations by province

Some provinces also have their own energy efficiency regulations for many of the federally regulated products – find out which ones!

Energy efficiency standard

Energy performance standard for household gas boilers
Energy-using product AFUE Requirements
Household gas boilers that are intended for low pressure steam systems ≥ 80% No continuously burning pilot light
Household gas boilers that are intended for hot water systems ≥ 82% No continuously burning pilot light
Household gas boilers that are intended for hot water systems and have tankless domestic water heating coils ≥ 82% No continuously burning pilot light
Household gas boilers that are intended for hot water systems and do not have tankless domestic water heating coils ≥ 82% No continuously burning pilot light

Equipped with automatic water temperature adjustment device and not operable without the device
