ENERGY STAR qualified central air conditioning systems are about 8 percent more efficient than standard models. The energy efficiency of this product is measured by a Seasonal Energy Efficiency Ratio (SEER) and an Energy Efficiency Ratio (EER). Typical residential systems are "split" with a separate indoor evaporator unit in the furnace ducting and an outdoor condenser unit. There are also "single package" systems that have the evaporator and condenser in one unit. The following levels must be met or exceeded to qualify for ENERGY STAR:

Type SEER EER
Split >= 14.5 >= 12.0
Single Package >= 14.0 >= 11.0

Single package units with electric air-conditioning and gas heating cannot qualify for ENERGY STAR in Canada.

Boilers – Residential

List of models: Gas-fired boilers

List of models: Oil-fired boilers

Boilers designed for space heating can also provide domestic hot water for residential applications. There are two basic methods used:

  1. Indirect storage. These well-insulated tanks operate as a separate heating zone with substantially reduced heat losses and higher efficiencies as compared to tankless coils.

  2. Tankless coil. Operating a boiler with a tankless coil will reduce the overall energy efficiency of the boiler.

Water Heaters

List of models: Gas Water Heaters
List of models: Tankless Water Heaters

ENERGY STAR qualified water heaters use at least 5 percent less energy than conventional models. The energy efficiency performance for water heaters is measured by the Energy Factor (EF). The higher the EF, the more efficient the water heater. There are also requirements for the First-Hour Rating (FHR) of the storage, condensing and heat pump water heaters. The FHR is the amount of hot water in litres a water heater can supply in one hour starting with a full tank. For tankless water heaters, the rating used is Litres per minute (LPM). LPM is the amount of hot water in litres per minute that a tankless water heater can supply over a 42.8 Celcius degree rise. The following types of water heaters must meet or exceed the following EF levels in order to qualify as ENERGY STAR:

January 1, 2009
Product Category Minimum Efficiency Rating First – Hour Rating
Gas storage water heater
Until August 31, 2010
EF ≥ 0.62 FHR ≥ 254 litres per hour
Gas storage water heater
As of September 1, 2010
EF ≥ 0.67 FHR ≥ 254 litres per hour
Gas tankless water heater EF ≥ 0.82 LPM ≥ 9.5 over 42.8°C rise
Condensing gas storage water heater EF ≥ 0.80 FHR ≥ 254 litres per hour
Heat pump water heater EF ≥ 2.0 FHR ≥ 190 litres per hour
Solar water heater Net solar energy contribution equivalent to ≥ 7.0 GJ/year

Ceiling Fans

ENERGY STAR qualified ceiling fans move air up to 20 percent more efficiently than standard ceiling fans.

Fan Speed Minimum Airflow Efficiency Requirement
Low 35.4 m3/min. (1250 cfm) 4.4 m3/min (155 cfm) per watt
Medium 85.0 m3/min. (3000 cfm) 2.8 m3/min (100 cfm) per watt
High 141.6 m3/min. (5000 cfm) 2.1 m3/min (75 cfm) per watt

If your ENERGY STAR qualified ceiling fan doesn't include lighting and you wish to add it, be sure to purchase an ENERGY STAR qualified light kit. These kits come with either pin-based compact flourescent lamps (CFLs) or screw-based CFLs. This lighting is more efficient than standard incandescent lighting and long lasting, so you won't have to make frequent bulb changes.

Ceiling Fan Tips:

  • Fans should be installed with the blades at least 30 cms below the ceiling, 200 cms from the floor and 60 cms from the nearest wall.
  • Air should be moved downwards from the ceiling in the summer to provide a cooling breeze on the room occupants.
  • If the fan is used in the winter, air should be moved upwards towards the ceiling to disperse the warm air that tends to accumulate there and distribute it more evenly in the room.
  • During the summer, switch the fan and light off when you leave the room. Fans don't actually cool a room, they just cool circulate the air.

Residential Furnaces (forced-air)



Furnaces – Gas or Propane

List of models: Gas and propane fired furnaces

A gas or propane fired furnace's energy efficiency performance over a heating season is called the Annual Fuel Utilization Efficiency (AFUE). This AFUE is expressed as a percentage. The higher the percentage, the more efficient the furnace.

Some high-efficiency furnaces using a variable-speed direct current (DC) motor to run the air circulation fan, can significantly reduce electricity consumption while providing better heat distribution.

Residential gas or oil furnaces must have an annual fuel utilization efficiency (AFUE) rating of 90 or higher to qualify for the ENERGY STAR mark. Some high-efficiency furnaces using a variable-speed direct current (DC) motor to run the air circulation fan, can significantly reduce electricity consumption while providing better heat distribution.

Furnaces – Oil

List of models: Oil-fired Furnaces

An oil fired furnace's energy efficiency performance over a heating season is called the Seasonal Energy Utilization Efficiency (SEUE). This SEUE is expressed as a percentage. The higher the percentage, the more efficient the furnace. For furnaces with no standing pilot light, the SEUE is equivalent to the Annual Fuel Utilization Efficiency (AFUE).

Residential oil furnaces must have an annual fuel utilization efficiency (AFUE/SEUE) rating of 85% or more to qualify for the ENERGY STAR symbol.

Heat Pumps – Ground-Source

List of models: Ground source heat pumps

Ground-source heat pumps use the thermal energy of the ground or groundwater to provide a source of heating and/or cooling for a home. There are three basic types: 1) closed loop; 2) open loop; and 3) direct expansion. The cooling function is measured by an Energy Efficiency Ratio (EER), and the heating function is measured by a Coefficient of Performance (COP). The higher the EER or COP number, the more efficient the heat pump is. ENERGY STAR qualified ground-source heat pumps must meet or exceed the following EER and COP levels:

Type EER COP
Closed Loop 14.1 3.3
Open Loop 16.2 3.6
Direct Expansion 15.0 3.5
