Oil-fired furnaces

Energy Efficiency Regulations

Regulatory definition

Oil-fired furnace, a warm-air furnace, other than a furnace for a mobile home or recreational vehicle that has an input rate of not more than 65.92 kilowatts (225 000 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

Manufactured on or after July 3, 2019

For models manufactured prior, refer to the Regulations

Compliant product models

Oil-fired furnaces as listed on NRCan’s searchable database

Testing standard

CSA P.2, for annual fuel utilization efficiency
10 C.F.R. Appendix AA, for FER

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 oil-fired furnaces
Product class Minimum annual fuel utilization efficiency Minimum FER
≤ 66 kW
(225 000 Btu/h)
≥ 78% FER = 0.071 × QMax + 382

FER = fan energy rating
kW = kilowatts
Btu/h = British thermal units per hour
QMax = airflow in cfm
