Canada's Energy Efficiency Regulations

Gas Furnaces

Final Bulletin – December 2008

ecoACTION - Using Less - Living Better.

Residential gas furnaces are prescribed as regulated products under Canada's Energy Efficiency Regulations (the Regulations). Natural Resources Canada (NRCan) has amended the Regulations to require dealers to comply with more stringent minimum energy performance standards for residential gas furnaces, imported or shipped inter-provincially, for sale or lease in Canada. The Regulations also contain a reporting requirement for electricity consumption of the furnace fan, blower motor and standby power.

This amendment is included in Canada's Clean Air Regulatory Agenda and accompanying Notice of Intent as published in the Canada Gazette October 21, 2006.

The legal text of the amendment is published in the Canada Gazette, Part II.

Background

Residential gas-fired furnaces are prescribed as regulated products under Canada's Energy Efficiency Regulations (the Regulations) since 1995. Natural Resources Canada (NRCan) has amended the Regulations to require dealers to comply with more stringent minimum energy performance standards for residential gas furnaces, imported or shipped inter-provincially, for sale or lease in Canada. As well, the Regulations contain a reporting requirement for electricity consumption of the furnace fan blower motor and standby power.

NRCan first proposed higher efficiency standards for gas-fired furnaces in 1999. At that time, it was not considered viable due to low take-up of high efficiency furnaces, lower fuel costs, and other factors. In 2006, NRCan undertook an update of the original study to account for increases in fuel costs, changes in product pricing and an increase in the penetration rate of high efficiency furnaces in the Canadian market. Based on these changed factors, NRCan considered it to be candidate for increased minimum energy performance.

NRCan then conducted considerable research and consultation including two studies on condensing gas furnaces in Canada, a workshop to solicit feedback on the studies’ findings, economic and environmental analysis based on the feedback, and extensive other consultations with industry.

After a review of ongoing stakeholder consultation and further feedback received from the 75 day comment period outlined in the March 29, 2008 edition of the Canada Gazette, Part I, NRCan incorporated aspects of the comments received into the Regulation. Those changes are reflected in the product descriptions, electrical consumption requirements and effective dates below.

Product description

For the purposes of the Regulations, a gas-fired furnace means an automatic operating gas-fired central forced-air furnace that uses propane or natural gas and has an input rate not exceeding 65.92 kW (225 000 Btu/h).

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

Furnaces for use in a mobile home or a recreational vehicle are not included in the Regulations.

Minimum performance levels

The minimum performance level, Annual Fuel Utilization Efficiency (AFUE), for gas-fired furnaces with an input rate not exceeding 65.92 kW (225 000 Btu/h) shall be 90%.

There is no change to the minimum performance level for furnaces intended to be installed outdoors. It will remain at 78% AFUE.

Energy performance test procedure

The test method used to determine efficiency is CSA P.2-07 Testing method for measuring the annual fuel utilization efficiency of residential gas-fired furnaces and boilers.

Effective date

This amended energy efficiency regulation for gas-fired furnaces will come into effect on December 31, 2009.

For through-the-wall gas-fired furnaces only, the regulation will come into effect on December 31, 2012.

All gas-fired furnaces that have their manufacturing process completed on or after the effective date, and that are subject to the Regulation, will be required to meet the stated efficiency level.

Labelling requirements

There is no requirement for the unit to have a label showing its energy efficiency.

Verification requirements

There is no change at this time to the verification requirements.

Reporting requirements

Energy efficiency reports

In addition to current reporting requirements for gas furnaces, the energy efficiency report required for this product will include the following information:

  • Maximum heat input and output capacities
  • The type of unit (central, outdoor with integrated cooling, or through-the-wall)
  • Average annual electrical energy consumption
  • If the unit has an integrated cooling component
  • Blower motor consumption (BE) in watts and voltage at heating speed
  • Blower motor consumption (BEc) in watts and voltage at circulation speed
  • Power burner motor consumption (PE) in watts, and voltage
  • Standby power consumption (kWstdby) when the unit is powered and on standby
  • As an alternative to conducting the additional measurements as stated above, a manufacturer may opt to select a default value as follows:
    • BEc = 0.20 × BE (for Brushless permanent magnet DC type motor)
    • BEc = 0.80 × BE (for Permanent Split Capacitor (PSC) type motor)
    • kWstdby = 0.0188 kW.

The addition of furnace electrical consumption reporting requirements will not affect the AFUE calculation method or its overall value.

This report must be submitted by the dealer to NRCan before the product is imported into Canada or traded interprovincially.

Importing reports

A dealer who imports these products into Canada must include the following information on the Customs release document:

  • Type of product
  • Model number
  • Brand name
  • Name and 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)

Harmonization

The efficiency level harmonizes with regulations in effect in the Provinces of Ontario and British Columbia.

  • Under the Ontario Building Code, all gas furnaces installed in new residential constructions must meet a minimum efficiency level of 90% AFUE as of January 1, 2007.
  • British Columbia's energy efficiency regulations require all new residential constructions using gas furnaces to be a minimum of 90% AFUE as of January 1, 2008. Gas furnaces installed in existing dwellings are required to meet the level by December 31, 2009.
