If you're always looking for ways to cut back on your utility bills, you'll like this helpful tip. When it comes to large chest freezers, the ones that are filled to the brim use far less energy than the ones that are mostly empty. Even if you don't have enough food to fill yours, you can use this system to maximise your freezer's efficiency.

Skill level:

Things you need

  • Several plastic milk or water jugs
  • Water
  • Chest freezer

  1. 1

    Organise your chest freezer. Stack boxed items neatly, keeping similarly shaped items close together and arranging the contents with the best economy of space.

  2. 2

    Fill several plastic milk or water jugs with regular tap water. Replace the caps tightly on each jug.

  3. 3

    Stack or arrange the jugs in the remaining space in your chest freezer. If more empty space remains, continue saving and filling plastic jugs until it's completely full.

  4. 4

    Make room for new food items as needed by removing the frozen jugs and setting them near the freezer.

  5. 5

    Keep the freezer full at all times by adding or replacing jugs as food is removed.

Tips and warnings

  • Solids and liquids maintain their temperature much better than oxygen, which is why this technique keeps freezer temperatures so stable.
  • Leave about an inch of room when filling the jugs with water; water expands as it freezes.
