Freezer consumes a lot of electricity – trick reduces consumption by 50 percent


Many households cannot do without a chest freezer. But it is considered a big power guzzler. But you can reduce consumption with a few tricks.

Many households cannot do without a chest freezer.

But it is considered a big power guzzler.

But you can reduce consumption with a few tricks.

Hamburg/Dortmund – Even if the state is currently helping with the electricity price brake: electricity is expensive.

Apart from that, saving energy protects the environment and your wallet.

Does the freezer for storing and freezing food still have a future?

After all, the chest freezer is one of the biggest energy guzzlers in private households.

But how much electricity does a freezer need and can consumption be reduced?

Chest freezer consumes a lot of electricity: This is how high the energy consumption is per year

In principle, a freezer is not the same as a freezer and a freezer is not the same as a freezer.

How much electricity a device uses depends on several factors such as size, volume and age.

The portal

gives a rough overview:

  • Small freezers (up to 200 liters): approx. 100 - 200 kWh

  • Large freezers (over 200 liters): approx. 125 - 225 kWh

  • Freezers (up to 600 liters): approx. 125 - 300 kWh

Assuming an annual electricity consumption of 100 to 300 kWh (kilowatt hours), the costs resulting from the electricity consumption of a freezer or chest freezer are between EUR 37 and EUR 111 at an electricity price of EUR 0.37 per kWh.

Power guzzler freezer: Is a new freezer worth it?

New electrical devices usually have better energy efficiency.

Against the background of rising electricity prices, many people ask themselves whether and when it is worth swapping old for new (more savings tips at RUHR24).


portal informs that the energy efficiency classes of old and new devices are economically decisive


From an environmental point of view, replacing freezers is even worthwhile if they are still working.

The following therefore applies:

  • If the old device was bought before 2001, it should be exchanged for a device with energy efficiency class A+++ or better

  • If the old appliance has energy efficiency class B, a new freezer with classification A+++ can save a lot of electricity.

Replacing the freezer or chest freezer: When does it make sense to buy a new one?

If you have an "oldtimer" in the basement, i.e. a freezer or chest freezer that is at least 20 years old, you can exchange this device for a new device with a clear conscience.

According to the Öko-Institut, the energy saved should justify the resource consumption of the new device over the lifetime.

If you buy a new device, it is worth making sure that it fits your needs.

On the one hand, a usable capacity of around 50 to 80 liters can be estimated per person in the household.

On the other hand, it depends on whether someone wants to store finished products or precook them and freeze larger quantities at once.

Defrost and set up properly: This is how energy can be saved with the freezer

As far as power consumption is concerned, the adjusting screw can also be turned with a new chest freezer or freezer.

There are a few simple things to keep in mind to save a few kilowatt hours year after year.

The place where the cooling device is located can be decisive in determining whether the chest freezer becomes a power guzzler or not.

If the temperature around the device is high, it will increase the power consumption.

A place in the basement or in a cool storage room, on the other hand - far away from heating, stove, tumble dryer or dishwasher - is ideal for saving electricity.

Regularly defrosting your freezer can also save you money.

The thin layers of ice that form inside the device over time can be a sign of leaks or that the lid has been left open for too long.

Generally speaking, the thicker the layer of ice, the more power the device consumes.

Regular defrosting can save between 15 and 45 percent of electricity,

Freezer consumes a lot of electricity - these tips reduce consumption immediately

Other tips for saving energy include opening the refrigerator door for as little time as possible and leaving it open.

If you keep your freezer tidy, you will find your frozen peas right away and close the door quickly.

In addition, do not use the Superfrost function.

Sure, it freezes food faster, but it also consumes a lot of electricity. 

Dirty door seals can also have a negative effect.

Cold can escape and it takes more electricity to maintain the temperature.

Manufacturers recommend cleaning door seals regularly with clear water. 

Freezer vs Deep Freezer: Which Appliance Uses More Power?

Deep freeze or a freezer?

Here opinions differ.

In summary, it can be said that the capacity of freezers is up to 300 liters and the average power consumption is 100 to 350 kilowatt hours per year.

The operating costs range between 35 and 150 euros per year.

Freezers are available with a capacity of up to 600 liters.

Energy consumption should be between 100 and 600 kilowatt hours per year.

A chest freezer has electricity costs between 50 and 180 euros.

The same applies here: the power consumption increases with increasing capacity.

It's not just electricity that's getting more expensive, the price of groceries has also increased.

Supermarket customers experienced a price shock for cucumbers, for example.
