Technical bulletin on amending the standard
On April 30, 2016, Natural Resources Canada's (NRCan) Office of Energy Efficiency issued a Notice of Intent to align Canada’s EnergyEfficiency Regulations (the Regulations) for gas furnace fans 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 gas furnace fans.
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.
Gas furnaces were first regulated in Canada in 1995. The current regulation only sets minimum energy performance standards (MEPS) for the fuel efficiency of gas furnaces. On July 3, 2014, the United States Department of Energy (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 introducing MEPS which would limit the electrical consumption of gas furnace fans. If implemented, this proposal would ensure the Regulations for gas furnace fans are aligned with those of the U.S. DOE.
A gas furnace fan is the indoor air moving component of the furnace that is designed to supply heating and/or cooling through a system of ducts 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
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 Appendix Aa to Subpart B of Part 430 - Uniform Test Method for Measuring the Energy Consumption of Furnace Fans.
Energy performance standard
|Product type||Fan energy rating (FER)
|Gas furnaces that have an input rate of ≤ 65.92 kW (225,000 Btu/h), use single-phase electric current and do not have an integrated cooling component||FER = 0.044 x QMax1 + 195|
|Gas furnaces that are through-the-wall, have an input rate of ≤65.92 kW (225,000 Btu/h), use single-phase electric current and have an integrated cooling component||FER = 0.044 x QMax1 + 195|
|Gas furnaces that are outdoor furnaces, have an input rate of ≤ 65.92 kW (225,000 Btu/h), use single-phase electric current and have an integrated cooling component||FER = 0.044 x QMax1 + 199|
1QMax 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 new standards will apply to gas furnaces that have been manufactured on or after July 3, 2019.
NRCan is not proposing labelling requirements for gas furnace fans at this time.
Equipment will continue to carry a third party verification mark indicating that the product meets the MEPS (i.e. annual fuel utilization efficiency (AFUE) and the proposed 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 gas furnaces will include the following product specific information, in addition to the reporting requirements already in place for gas furnaces:
- 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 inter-provincially for the first time.
There is no change proposed to import reporting requirements for gas furnaces.
The purpose of this bulletin is to provide stakeholders with technical detail required to comment on the requirements under consideration for gas furnace fans.
Natural Resources Canada is specifically interested in:
- receiving FER rating data for gas 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.
