How Much Electricity Does a Chest Freezer Use?

Electricity seems to be an ever-rising household expense, but do you know how much each household appliance actually uses? Despite being "always on" the relatively low cost daily of running a freezer might surprise you.

How Energy Efficient are Chest Freezers?

On the freezer specification details, look for annual energy usage - it will be shown as a KWh figure (1Kwh = 1 unit of electricity).

How to Use Your Freezer Efficiently

Here are some simple tips to ensure your freezer operates most economically:

  • 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
