ENERGY STAR®
Qualifying Criteria for
Furnaces (forced-air)

Version 2.0, October 27, 2006

Furnaces must meet Canada's Energy Efficiency Regulations before they can qualify for the ENERGY STAR symbol in Canada.

Under the Energy Efficiency Regulations, the AFUE performance level for gas fired furnaces was raised to 90% effective January 1, 2010. Until a more stringent ENERGY STAR specification is finalized, ENERGY STAR qualifications for gas fired furnaces are no longer recognized in Canada.

The ENERGY STAR specification for gas-fired furnaces is currently under revision. Materials related to this revision process are provided below. Participants and other interested parties with questions or concerns regarding the revision process can consult the U.S. Environmental Protection Agency website.

1.   Definition

a.   Furnace – a heating unit with a heat output of less than 65.92 KW (225,000 Btuh) whose function is the combustion of fossil fuel for space heating with forced hot air. The unit must include burner(s), heat exchanger(s), blower(s) and connections to heating ducts. A heating unit that meets this definition and also provides hot water for domestic or other use may be considered a furnace for the purposes of this criteria.

b.   Annual Fuel Utilization Efficiency (AFUE) – a measure of the amount of fuel converted to space heat in proportion to the amount of fuel entering the furnace. This is commonly expressed as a percentage. Test procedures to determine the AFUE are identified below in Section 4.

c.   Manufacturer Limited Warranty – For the purposes of this arrangement, a manufacturer limited warranty is an assurance by the Participant that purchased system equipment and components are warranted by the manufacturer for a period of time. The period of time is typically expressed in numbers of years. The exact terms of the limited warranty shall be determined by the Participant.

2.  Qualifying Products:

Any furnace that meets the definition in Section 1A is eligible for ENERGY STAR qualification.

3.  Energy-Efficiency Specifications:

Only those products listed in Section 2 that meet the following Tier I and Tier II criteria may qualify as ENERGY STAR. Proposed effective dates for Tiers I and II are covered in Section 5 of this specification.

Tier I

Oil furnace models: > = 83% AFUE rating

In addition Participant will:

  • Include a manufacturer limited warranty with its qualified furnace models.
  • Consider using high efficiency electric blower motors with its qualified furnace models.

Tier II

Oil furnace models: > = 85% AFUE rating

In addition Participant will:

  • Include a manufacturer limited warranty with its qualified furnace models.

4.  Test Criteria:

To qualify for ENERGY STAR in Canada, manufacturers must first demonstrate that they meet the requirements of the Regulations of Canada's Energy Efficiency Act. The ENERGY STAR Participant agrees to measure a furnace model's energy-efficiency using the following test procedures, which are in accordance with those required under Canada's Energy Efficiency Regulations:

CAN/CSA-B212-00 (oil-fired)

5.  Effective Date:

The date that manufacturers may begin to qualify products as ENERGY STAR, under this Version 2.0 specification, will be defined as the effective date of the agreement. Any previously executed agreement on the subject of ENERGY STAR qualified furnaces shall be terminated effective September 30, 2006.

  1. Qualifying Products Under Tier I of the Version 2.0 Specification:
    The first phase of this specification is proposed to commence on October 27, 2006. All products, including models originally qualified under Version 1.3, with a date of manufacture on or after October 27, 2006, must meet the new (Version 2.0) requirements in order to qualify for ENERGY STAR. The date of manufacture is specific to each unit and is the date (e.g. month and year) of which a unit is considered to be completely assembled.

  2. Qualifying Products Under Tier II of the Version 2.0 Specification:
    The second phase of this specification, Tier II, is proposed to commence on October 1, 2008. All products, including models originally qualified under Tier I, with a date of manufacture on or after October 1, 2008, must meet the Tier II requirements in order to qualify for ENERGY STAR.

  3. Natural Resources Canada or the US Environmental Protection Agency will not allow grandfathering under this Version 2.0 ENERGY STAR specification.

ENERGY STAR qualification under previous Versions is not automatically granted for the life of the product model. Therefore, any product sold, marketed, or identified by the manufacturing partner as ENERGY STAR must meet the current specification in effect at the time of manufacture of the product.

6.  Future Specification Revisions:

Natural Resources Canada and the United States Environmental Protection Agency reserve the right to revise the specification should technological and/or market changes affect its usefulness to consumers or industry or its impact on the environment. In keeping with current policy, revisions to the specification will be discussed with stakeholders.
