Bulletin on amending the standards - as published
October 2011 – as published
Canada's Energy Efficiency Regulations (the Regulations) have been amended in order to strengthen the minimum energy performance standards for gas and oil-fired boilers and introduce prescriptive requirements for boilers, including electric boilers imported or shipped inter-provincially, for sale or lease in Canada. The amendment has been published in the Canada Gazette, Part II. This amendment comes into force six months after publication, on April 12, 2012.
Three earlier bulletins were distributed in the development of this standard and are available at /regulations/16846. The amendment was pre-published in the Canada Gazette, Part I on June 12, 2010.
The Regulations apply to gas, oil-fired and electric boilers intended for application in a low pressure steam or hot water central heating system and have an input rate of less than 88 kilowatts (300,000 Btu/h). The Regulations do not apply to electric boilers equipped with tankless domestic water heating coils.
Energy Performance Test Procedures
The test method used to determine the efficiency of gas boilers is CSA P.2-07 Testing method for measuring the annual fuel utilization efficiency of residential gas-fired furnaces and boilers.
The standard is available from:
Canadian Standards Association
5060 Spectrum Way, Suite 100
In Toronto, call 416-747-4000
The test method used to determine the efficiency of oil-fired boilers is ASHRAE 103-2007 Method of testing for annual fuel utilization efficiency of residential central furnaces and boilers.
The standard is available from:
American Society of Heating, Refrigerating and Air-Conditioning Engineers
1791 Tullie Circle, N.E.
Atlanta, GA 30329
Energy Performance Standards
The minimum annual fuel utilization efficiency (AFUE) and prescriptive requirements are detailed in the following table based on date of manufacture.
|Boiler type||September 1, 2010||September 1, 2012|
|Minimum AFUE||Prescriptive requirements||Prescriptive requirements|
|Gas Hot Water||82%||No constant burning pilot||Automatic means for adjusting water temperature|
|Gas Hot Water equipped with tankless domestic water heating coils||82%||No constant burning pilot||n/a|
|Gas Steam||80%||No constant burning pilot||n/a|
|Oil Hot Water||84%||n/a||Automatic means for adjusting water temperature|
|Oil Hot Water equipped with tankless domestic water heating coils||84%||None||None|
|Electric Hot Water||None||n/a||Automatic means for adjusting water temperature|
As of April 12, 2012, all gas and oil-fired boilers will be required to meet the regulatory requirements if their manufacturing process is completed on or after September 1, 2010.
Additionally, gas, oil-fired and electric boilers that have their manufacturing process completed on or after September 1, 2012 will be required to meet the prescriptive requirement of an automatic means for adjusting water temperature where applicable.
There is no requirement for gas, oil-fired and electric boilers to have a label showing its energy efficiency.
There is no change to the verification requirements currently in place for residential gas and oil-fired boilers.
The same verification requirements that apply to other products regulated under the Energy Efficiency Act apply to electric boilers.
These products will carry a verification mark indicating that the energy performance of the product has been verified.
The verification mark is the mark of a Standards Council of Canada (SCC) accredited certification body that administers an energy performance verification program for this product.
Energy Efficiency Reports
The energy efficiency report required for gas and oil-fired boilers will include the following information:
- fuel the product uses – (natural gas, propane or oil)
- type of system (hot water or low pressure steam)
- input rate in kW (gas) and Btu/h (oil)
- power burner motor’s consumption in kW
- water pump electrical energy consumption in kW
- type of device used to automatically adjust the water temperature.
The energy efficiency report required for electric boilers will include the following information:
- input rating in kW
- type of device used to automatically adjust the water temperature
This report must be submitted, by the dealer, to the Minister of NRCan before the product is imported into Canada or traded interprovincially for the first time.
A dealer who imports gas, oil-fired and electric boilers into Canada must include the following information on the customs release document:
- type of product
- model number
- brand name
- address of the dealer importing the product
- purpose for which the product is being imported (i.e. for sale or lease in Canada without modification; for sale or lease in Canada after modification to comply with energy efficiency standards; or for use as a component in a product being exported from Canada)
NRCan attempts to harmonize with other regulatory agencies. This amendment harmonizes with the levels and prescriptive requirements coming into effect in the U.S. September 1, 2012. Canada’s required AFUE levels and elimination of standing pilots comes into effect two years earlier than the U.S. as agreed to with industry.
