Quick Facts on Clothes Dryers

Today's clothes dyers are about 18 percent more energy efficient than they were in 1990. There is no ENERGY STAR® specification for dryers.


The main improvements in the energy efficiency of clothes dryers are due to automatic controls that end the cycle by using moisture sensors, thus eliminating over-drying. Drying times are shorter too when combined with ENERGY STAR qualified clothes washers that remove water more effectively.

Testing today (CSA Standard C361-92)
Compact clothes dryers (drum volume less than 125 litres) and standard clothes dryers (drum volume greater than or equal to 125 litres) are tested for energy consumption.

For a compact dryer, the test load weighs 1.36 kilograms (dry weight). For a standard dryer, the test load weighs 3.17 kilograms (dry weight). The test load is made up of pieces of cloth measuring 60 × 60 centimetres that are 50 percent cotton and 50 percent polyester.

The tester wets the load (making it 70 percent heavier) and puts it in the spin cycle of a clothes washer. The energy consumption needed to dry this test load to 4 percent more than its original dry weight is now measured. This is the energy consumption, per cycle, for the clothes dryer.

Calculating the EnerGuide Rating
The energy consumption per drying cycle is multiplied by 416 (the average number of times a Canadian household uses a clothes dryer in one year). This is the value on the EnerGuide label.

Note: Extra credit is given for dryers that have an automatic control that turns off the dryer when sensors indicate that the load is dry.
