Energy Efficiency Regulations
Regulatory definition
Gas furnace, an automatic operating gas-fired central forced air furnace that uses propane or natural gas and has an input rate of not more than 117.23 kW (400,000 Btu/h). It does not include a furnace for a park model trailer or a recreational vehicle.
Gas furnace for relocatable buildings, a gas furnace that is intended for use in a temporary modular building that can be relocated from one site to another and is marked for use in relocatable buildings.
Manufactured home, a factory-built, single- or multiple-section, one-storey dwelling that:
- is designed and constructed for year-round occupancy;
- is designed to be transported to its installation site; and
- is ready for occupancy when it is installed in accordance with the manufacturer’s installation instructions.
Replacement non-condensing gas furnace, a non-condensing gas furnace that is marked for use as a replacement for a non-condensing gas furnace in a manufactured home.
Space constrained gas furnace, a gas furnace that uses single-phase electric current and has an outdoor unit:
- That has an overall displacement that is – or two or more overall exterior dimensions that are – substantially smaller than those of other units of a similar heating capacity that are usually installed in single-family homes, and
- With respect to which an increase in the overall displacement or two or more overall exterior dimensions would result in a considerable increase in the usual cost of installation or in a significant loss in the utility of the product to the consumer.

Energy efficiency regulations by province
Some provinces also have their own energy efficiency regulations for many of the federally regulated products – find out which ones!
Energy efficiency standard
| Input rate/description | Product type | Minimum AFUE | FER |
|---|---|---|---|
| Gas furnaces, other than gas furnaces for relocatable buildings or replacement non-condensing gas furnaces, that have an input rate of ≤ 65.92 kW (225,000 Btu/h), use single-phase electric current | Gas furnaces without an integrated cooling component | 95% | ≤ 0.044 × QMax + 195 |
| Outdoor furnaces with an integrated cooling component | 78% | ≤ 0.044 × QMax + 199 | |
| Space-constrained furnaces with an integrated cooling component | 90% | N/A | |
| Gas furnaces for relocatable buildings | 80% | ≤ 0.071 × QMax + 222 | |
| Replacement non-condensing gas furnaces | 80% | ≤ 0.071 × QMax + 222 | |
FER = fan energy rating
kW = kilowatts
Btu/h = British thermal units per hour
QMax = airflow in cfm
