10 Ways To Make Your Old Fridge More Energy Efficient

Energy Efficient Fridge

Perhaps it is no surprise that a refrigerator is one of the most energy consuming appliances in UK households. Whilst brand new fridges are constantly innovating ways to be energy efficient, it is expensive to keep up with the latest tech! With that mind, it is helpful to know some easy tricks and tips on how you could save some energy with your fridge, no matter how old!

1. Keep The Door Shut

Whilst this might be an obvious point, simply keeping the door of your fridge shut ensures that cold temperatures stay inside. No matter if your fridge is new or old, it is advisable to only open your fridge for short periods of time. Simply think about what you would like to eat or drink before you open your fridge, rather than deciding with the door wide open. This is certainly the cheapest way to save energy!

2. Keep A Check On The Temperature 

You may think your fridge is simply “cold”, however subtle differences in the temperature, similarly to air-conditioners, can make a big difference in your energy bill. The ideal temperature for a fridge is between 1-5C, and around -18C for your freezer. Whilst slightly warmer temperatures would be sufficient in cooling the food, these guidelines were selected on the basis of killing most bacteria, while preserving essential vitamins of fresh goods. In short, you can make your fridge more energy efficient, by simply regulating the temperature!

3. Store Your Food Well

This is might be a surprising tip, but how you store your food in the fridge can have a large impact on its energy efficiency. For one, keeping your leftovers from dinner in a glass container over a plastic box helps to absorb and retain the cold better. To stop overworking your fridge’s compressor, always make sure any food and liquids are covered, as a general rule.

4. Check The Seal Of Your Fridge 

This energy tip will more likely apply to you if you have an older fridge. If the seal of your fridge has worn off, the cold air inside will escape, and your fridge will have to work harder to keep cool. An obvious sign of this is when you see condensation outside of your fridge. 

For this reason, always make sure the seals are kept clean and watch out for any cracks that may have developed over the years.

5. Don’t Put Hot Food In Your Fridge

Another tip is to leave your cooked food to cool down on the counter before putting it in your fridge. Why? Because you’ll save your fridge some energy by not making it work extra hard to cool down piping hot food!

6. Clean The Coils

Coils are the heart and soul of your fridge. For this reason, you want to make sure they are in good condition by cleaning them at least once a year. This is best done when the fridge has been emptied and unplugged. 

By simply cleaning the coils, it is said your fridge could become up to 30% more energy efficient. 

7. Organise Your Food 

As you might remember from your school days, hot air rises, and cold air falls. Placing your meats near a cold spot will therefore keep them fresh, whereas vegetables could potentially spoil in those very same spots.

8. Check Your Room Temperature

Whilst your refrigerator will hopefully be strongly sealed, the outside temperature of the room can have a surprising impact on your fridge’s energy efficiency. It is said that even a few degrees Celsius above average room temperature, could have your fridge working 20% more to keep cool. On hot summer days it is therefore recommended to keep your blinds drawn.
Another tip to stop your fridge from overheating, is to make sure you leave some space between the fridge and any walls or cupboards next to it. This allows for extra ventilation, and will help you save energy!

9. Make Sure To Defrost!

If your fridge has a layer of frost on the inside, it might be time to defrost! Anything over 1cm thickness should be removed to ensure your fridge can work more efficiently, and to help you save energy.

10. Fill Your Freezer

Lastly, to help drive the efficiency of your fridge, keep your freezer full. The fuller your freezer, the better your fridge will work! This might also come in handy, in the case of a power outage. The more food and drinks and in your freezer, the longer it will take for any of your food in the fridge to go off.
