Technical bulletin on amending the standard
On April 30, 2016, Natural Resources Canada's Office of Energy Efficiency issued a Notice of Intent to align Canada’s Energy Efficiency Regulations (the Regulations) for oil-fired furnaces with standards in the United States. This technical bulletin has been released to initiate the consultation process and to collect stakeholder views on the requirements being considered for oil-fired furnaces.
Input received during this stage of the process will inform the development of the Amendment 14 proposal. In addition, the department will undertake a cost-benefit analysis using the best-available Canadian market data to assess the economic and environmental impacts of aligning these standards and to ensure Canadian consumers and businesses benefit from its implementation.
The Government of Canada intends to pre-publish a regulatory proposal in the Canada Gazette, Part I within approximately one year of this bulletin.
Oil-fired furnaces were first regulated in Canada in 1995. The current regulation only sets minimum energy performance standards (MEPS) for the fuel efficiency of oil-fired furnaces. On May 1, 2009, the United States Department of Energy (U.S. DOE) issued a final rule, which increased the stringency of these requirements. Subsequently on July 3, 2014, the U.S. DOE issued a final rule which set conservation standards for the electrical consumption of residential furnace fans.
Natural Resources Canada (NRCan) is considering
- increasing the stringency of the fuel efficiency of oil-fired furnaces
- changing the reporting metric of fuel efficiency from a seasonal energy utilization efficiency (SEUE) to an annual fuel utilization efficiency (AFUE)
- introducing MEPS which would limit the electrical consumption of oil-fired furnace fans
If implemented, this proposal would ensure the Regulations for oil-fired furnaces are aligned with those of the U.S. DOE.
Residential oil-fired furnaces are used to provide central heating to residential dwellings. Furnaces heat air and distribute the heated air through the house using ducts. The oil-furnace fan is the indoor air moving component of the furnace that is designed to supply heating and/or cooling with air as the heat transfer medium. The assembly typically consists of a fan motor and its controls, an impeller and housing.
Energy performance test procedure
For the measurement of the oil-furnace Fan Energy Rating (FER), NRCan is proposing to reference the U.S. DOE test procedure for residential furnace fans, as the energy performance test procedure
- U.S. Code of Federal Regulations (CFR) Title 10, Part 430, Subpart B, Appendix AA - Uniform Test Method for Measuring the Energy Consumption of Furnace Fans.
For the measurement of the annual fuel utilization efficiency (AFUE), NRCan is proposing to reference
- CSA P.2-13 - Testing method for measuring the annual fuel utilization efficiency of residential gas-fired or oil-fired furnaces and boilers.
The test procedure can be purchased from:

Energy performance standard
|Product type||Minimum AFUE1||FER2 (watt/CFM)|
≤ 66 kW (225,000 Btu/h)
|83%||Jan 1, 2017||FER = 0.071 x QMax + 382||July 3, 2019|
1 Annual fuel utilization efficiency
2 FER is Fan Energy Rating where QMax is the airflow, in cfm, at the maximum airflow-control setting.
These Regulations will come into force six months after the date of publication in the Canada Gazette, Part II.
NRCan proposes that the updated AFUE standards will apply to oil-fired furnaces manufactured on or after January 1, 2017 and the new FER requirements for those manufactured on or after July 3, 2019.
The products will continue to carry a third party verification mark indicating that the product meets the MEPS (i.e. the proposed annual fuel utilization efficiency (AFUE) and fan energy rating (FER)) and that the information to be reported has been verified.
The verification mark is the mark of a Standards Council of Canada accredited certification body that operates an energy efficiency certification program for the product.
Energy efficiency reports
The energy efficiency report required for oil-fired furnaces will include the following product specific information, in addition to the reporting requirements already in place:
- annual fuel utilization efficiency, AFUE
- airflow in CFM at maximum airflow control setting Qmax
- Fan Energy Rating, FER (watt/CFM)
The Regulations apply to products imported or shipped inter-provincially for sale or lease in Canada. This report must be submitted, by the dealer, to NRCan before the product is imported into Canada or traded interprovincially for the first time.
There is no change proposed to import reporting requirements for oil-fired furnaces.
The purpose of this bulletin is to provide stakeholders with technical detail required to comment on the requirements under consideration for oil-fired furnaces.
Natural Resources Canada is specifically interested in receiving FER rating data for oil-fired furnaces that are sold in Canada.
Additional information on Canada’s Energy Efficiency Regulations including a current list of Standards Council of Canada accredited certification bodies can be found in the Department’s website.
