Freezers and freezers turn out to be real power guzzlers if they are not defrosted regularly. Winter is just the right time for this.

Whether it's a freezer, freezer or freezer, almost everyone has a freezer at home to freeze frozen pizza, ice cream or leftovers. However, as soon as a thick layer of ice forms, it is better to defrost it – before the appliance mutates into the biggest power guzzler in the household.

Freezer: Thick layer of ice increases power consumption

Older freezers in particular tend to form a thick layer of ice quickly. As a result, the device has to cool even more and thus consume more power to reach the desired temperature. "Just one centimetre of ice can increase electricity consumption by 10 to 15 percent," Ökotest quotes BUND Hessen. The wrong location of the freezer can also increase electricity consumption by 3 percent.

However, if you want to pay attention to your power consumption, you should also keep an eye on the size of new devices. "100 liters more volume increases electricity consumption by 25 percent," informs the consumer advice center. As a rule of thumb, you should expect a useful capacity of approx. 50 to 80 litres per person.

Defrosting the freezer quickly – here's how to do it

If you defrost your freezer, you simply have to wait until the ice melts when the appliance is switched off. However, this can take several hours, depending on the thickness of the ice layer. It's quicker with this trick:

  • Clear out the freezer and temporarily store food (see below).
  • Unplug.
  • Place a bowl of hot (but not boiling) water in the freezer. Don't forget the coasters so that the device is not damaged. The heat causes the ice to melt faster.
  • Leave the door open.
  • Place several cloths under and in front of the freezer to collect the melt water.
  • A hot hair dryer can also speed up the defrosting process, but it is not advisable: water could drip onto the hair dryer – and then it becomes dangerous. In addition, the hair dryer also consumes electricity, which runs counter to the actual goal.

    Winter is the best time to defrost the freezer

    The ideal would be to empty the freezer or freezer before defrosting and consume all the food so that the cold chain is not interrupted. However, this is not always possible so quickly. The best time to defrost is therefore in winter: If there are sub-zero temperatures outside, you can simply temporarily store the frozen food on the balcony or terrace. Some even take advantage of the bitter cold in winter to turn off the fridge and save even more electricity – not always a good idea.

    Alternatively, you can ask neighbors to temporarily store your frozen food or use a cooler for sub-zero temperatures. In any case, the refrigerator is not suitable as a place to store it – the frozen food would thaw too much at around 7 degrees.
