Chest or cabinet: How much does a freezer consume on average?
As specified on the Master My Energy website, the average annual consumption of your freezer varies according to its energy class, its format and its capacity (in litres). To better understand this disparity, here is a table illustrating this difference:
| Energy class | Type of freezer | Ability | Average annual consumption |
| A+ | Chest | 240 L | 224 kWh/year |
| A+ | Armoire | 238 L | 260 kWh/year |
| A++ | Chest | 240 L | 186 kWh/year |
| A++ | Armoire | 240 L | 202 kWh/year |
| A+++ | Chest | 240 L | 127 kWh/year |
| A+++ | Armoire | 270 L | 168 kWh/year |
How to calculate the annual consumption of your freezer?
Did you know that it is possible to calculate the consumption of your appliances in kWh? No need to be good at math, because the formula is very simple! If you want to do this calculation, simply multiply the power of your device (in Watts) by the number of hours of use per day, the number of days of use per year, then divide everything by 1000 To make it clear, here is the formula to follow:
[puissance de l’appareil en Watts] x [nombre d’heures d’utilisation par jour] x [nombre de jours d’utilisation par an] / 1 000 = kWh name
Do we set an example? Get a pencil and a piece of paper, let’s go! So let’s assume you never turn off your freezer and it is at 30W power, the calculation would be: 30 x 24 x 365 / 1000 = 262.80 kWh per year. Child’s play, don’t you think?
Does an empty freezer consume a lot?
If, like us, you read the press every morning, there is no doubt that the piles of newspapers accumulate in a corner of your house and end up in the trash! But did you know that this most mundane-looking paper can have many other practical uses? Here is one of the many possibilities available to you!

According to the advice given on the site of the natural gas and green electricity supplier ENGIE, filling your freezer to 75% of its capacity optimizes the stabilization of its temperature. This is because when the door is open, a freezer full of food leaves less room for warm air to enter, which helps reduce energy consumption. To go even further, Sam Whillance, savings expert, recommend in the newspaper The Express, fill the empty space with newspaper. How ? Well, just by moving the food to the outer side and filling the space in the middle, your freezer will therefore be filled to 3⁄4 of its maximum capacity, saving you money!
Another method to reduce the electricity consumption of your fridge
If you don’t know, well, it’s time to tell you frankly: waste is not the only unfortunate consequence of frost! Apart from having to defrost your freezer regularly, frost also leads to an increase in the electricity consumption of your appliance. This is due to the fact that the ice acts as a kind of insulating layer between your food and the cooling system, clinging to the walls, do you realize that? Unfortunately, this forced insulation then forces him to redouble his efforts to maintain the interior temperature at an optimal level.
Result ? Food waste, but not only! the frost still ends up boosting your bills. And the height of all this is that you can’t escape it! This is why it is super important to tackle the problem by adopting preventive methods in order to avoid the formation of frost and the inconveniences that result from it…
