The Refrigerator Ice-Block Trick: The Surprising Physics Behind Saving Electricity Every Month

Every evening before going to bed, fill a medium, freezer-safe container or metal tray with clean tap water. Place it firmly f-l-frigo (in the freezer compartment). Because the kitchen is cool and the door remains sealed for the next 8 hours, the water will crystallize into solid ice with maximum thermal efficiency.

First thing in the morning, open the freezer and transfer your solid block of ice directly into the fresh food compartment, placing it on an upper shelf. As the ice sits f-l-tllaja (in the fridge) during the day, it will gradually thaw, absorbing internal heat and preventing the compressor from kicking on when the family opens the door.

To keep the appliance running efficiently, unplug your refrigerator twice a year and pull it away from the wall. Use a soft brush or vacuum attachment to gently strip away accumulated dust and pet hair from the condenser coils at the back or bottom. Clean coils dissipate heat rapidly, reducing electricity drain by up to 15%.
