Energy Efficiency Regulations

Note:

Amendment 14 to the Energy Efficiency Regulations was published in Canada Gazette Part II on October 31, 2018. While some provisions come into force upon publication, most provisions of this Amendment will come into force on April 30, 2019. The Guide to the Regulations will be updated with new requirements for affected products in time for the coming-into-force of the Amendment.

Regulatory definition

Gas furnace, an automatic operating gas-fired central forced air furnace that uses propane or natural gas and has an input rate of not more than 117.23 kW (400,000 Btu/h). It does not include a furnace for a mobile home or for a recreational vehicle.

Through-the-wall gas furnace, a gas furnace that is designed and marketed to be installed in an opening in an exterior wall that is fitted with a weatherized sleeve.

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 gas furnaces December 31, 2012
Input rate/description Product type Minimum AFUE Minimum TE
Testing standard CSA P.2
≤ 65.92 kW (225 000 Btu/h) using single-phase electric current Gas furnaces without an integrated cooling component 90%  
Outdoor furnaces with an integrated cooling component 78%  
Through-the-wall furnaces with an integrated cooling component 90%  
Testing standard CSA 2.3
≤ 65.92 kW (225 000 Btu/h) using three-phase electric current All products listed above 78% or 80%
> 65.92 kW (225 000 Btu/h) but ≤ 117.23 kW
(400 000 Btu/h)
All products listed above   80%
AFUE = Annual Fuel Utilization Efficiency
TE = Thermal Efficiency
kW = kilowatts
Btu/h = British thermal units per hour
