Freezers

Today’s new freezers use about eight per cent less energy than the average of those models in homes today. If a stand-alone freezer is necessary, there are two options: upright and chest freezers. Chest freezers are about 25 per cent more efficient than uprights.

Energy Star^®, an international program adopted by Natural Resources Canada, is a simple way for consumers to identify products that are among the most energy efficient on the market. Energy Star^® qualified freezers are available in all sizes of standard and compact models.

To qualify for the Energy Star^® label, appliances must exceed the minimum federal energy performance standard in Canada's Energy Efficiency Regulations by specific percentages. Energy Star^® freezers have two categories: standard size units must be 10 per cent more efficient while compact freezers must be 20 per cent more efficient. Chest models are generally more efficient than upright models because lifting the door loses less cold air.

The average life of a freezer is 21 years, so when buying a new one, a little energy efficiency research can be a good investment. There are two labels to look for when purchasing any new appliance. First, look for the Energy Star^® label to ensure the appliance meets the energy performance standard. Second, seek the EnerGuide label, which indicates the annual electricity that particular model would use under normal operating conditions. The EnerGuide label allows you to compare electricity use for different models.

Approximately 77 per cent of Alberta’s electricity is generated by non-renewable fossil fuels, a major source of greenhouse gas (GHG) emissions. Over 56 per cent of Alberta homes have a freezer, so energy efficient freezers can contribute to the province’s overall efficiency and GHG reductions.

Energy Savings Tips

Freezer motors and compressors generate heat, so allow enough space for continuous air flow around your freezer.
Ensure the freezer door seal is clean and tight as it can deteriorate over time. A simple test is to insert a piece of paper between the door and freezer. If the paper slips out easily, replace the seals. Another method is to put a light inside the freezer to check for leaks. If you can see light around the door gasket, the seals need replacing.
The freezer setting should be at -18° Celsius (C). Keeping temperatures just 5° C below recommended temperatures can increase energy use by as much as 25 per cent. Use a thermometer to check the temperature and adjust accordingly.
Keep the door closed, decide what you want from the freezer BEFORE you open the door.
Maintain your freezer at its optimum performance. Defrost a manual-defrost freezer when the ice thickness reaches half a centimetre. Ice build-up causes the compressor to operate longer.
Don't put your freezer near heat vents, sunlight or the oven.
