Oil-fired boilers - household

Energy Efficiency Regulations

Regulatory definition

Household oil-fired boiler, a boiler that is intended for application in a low pressure steam, or hot water central heating system, has an input rate of less than 87.92 kW (300 000 Btu/h) and that is either exclusively oil-fired, or capable of being fired, at the choice of the user, by either oil or another fuel.

Compliance date

Household oil-fired boilers manufactured on or after January 15, 2021

For models manufactured prior, refer to the Regulations

Compliant product models

Oil-fired boilers - household as listed on NRCan’s searchable database

Testing standard

ASHRAE 103-2007 or CAN/CSA-P.2-13

Energy efficiency standard

Energy performance standard for household oil-fired boilers
Energy-using product	AFUE	Requirements
Household oil-fired boilers that are intended for low pressure steam systems	≥ 85%	Standby power ≤ 11 W Off-mode power ≤ 11 W
Household oil-fired boilers that are intended for hot water systems and have tankless domestic water heating coils	≥ 86%	Standby power ≤ 11 W Off-mode power ≤ 11 W
Household oil-fired boilers that are intended for hot water systems and do not have tankless domestic water heating coils	≥ 86%	Equipped with automatic water temperature adjustment device and not operable without the device Standby power ≤ 11 W Off-mode power ≤ 11 W

AFUE = Annual Fuel Utilization Efficiency
