How Energy Efficient is My Chest Freezer?

The figures above should cover most modern freezers.

Your Specific Freezer

To find out exactly how much electricity your particular model uses, you will need to find its annual energy usage - it will be shown as a KWh figure (1Kwh = 1 unit of electricity).

Find the Usage Amount

You can find this information in the user manual, on the manufacturers website or on the energy efficiency label on the front of the unit. If it's a new freezer, then you can of course find it right here on our site.

Watts the Annual Cost

To find your annual running costs, simply multiply the annual kWh figure by the cost of your current electricity unit price which you can find on your bill - usually on page 2 under "unit rate"

How to Use Your Freezer Efficiently

Here are some simple tips to keep your freezer operating at peak performance:

  • Allow warm or hot food to cool down to room temperature before freezing
  • Regularly review the contents for expired items or those you know you will never use
  • Only open the lid when required and close as soon as possible
  • Keep the freezer 75% full - this is the most optimum level between airflow and mass
  • In summer, ensure the surrounding area (especially in a shed or garage) is properly ventilated and the unit is out of direct sunlight
  • Defrost on a regular basis - thick ice build-up reduces space and makes the freezer work harder
