The question of how many kilowatts consume refrigerator Indesitbecomes especially relevant with the constant increase in utility tariffs. The owner of household appliances is often faced with numbers on the tag, which may differ significantly from the total amounts in the electricity receipt. The difference between the indicators declared by the manufacturer and the actual energy consumption is explained by many variables, from the temperature in the room to the frequency of opening the door.
Modern models, such as the series Indesit EF or DS, are equipped with compressors operating in cyclic mode. This means that the device does not consume energy constantly, but only during moments of active cooling of the chamber. Understanding how much how many kW it takes to operate the unit allows you not only to predict the budget, but also to identify possible malfunctions if consumption suddenly increases.
In this article we will analyze in detail the technical characteristics, methods of independent calculation and factors affecting the energy efficiency of your refrigerator. You will learn to distinguish passport data from reality and learn how to optimize the operation of the device.
Passport data versus reality: what is written on the tag
The first thing you need to do to determine energy consumption is to find a sticker with technical information. It is usually located inside the refrigerator compartment on the side wall or on the rear panel of the cabinet. It is there that the energy consumption class is indicated, for example, A+ or A++, which gives a primary idea of the efficiency of the model. However, these data were obtained in laboratory conditions, far from a real kitchen.
The manufacturer tests the equipment at a strictly fixed ambient temperature, usually +25°C, and with the doors completely closed. In real life, we constantly open the refrigerator, loading warm food into it, which forces the compressor to work harder. Therefore, the actual consumption may exceed the declared ones kilowatt-hours by 20–30%.
It is important to pay attention to the annual consumption parameter, which is often indicated in kWh/year. Dividing this figure by 12, you will get an approximate monthly consumption, but remember that in winter, when apartments are cooler, the refrigerator will consume less energy, and in summer - more.
⚠️ Attention: If the sticker on your model is worn out or missing, the exact data can be found in the operating instructions or on the manufacturer's official website by entering the full model code (for example, Indesit C 132 G).
Factors influencing energy consumption
Electricity consumption by a refrigerator is not a constant value. It directly depends on the operating conditions and technical condition of the unit. One of the key factors is the room temperature. If the kitchen is located above a hot stove or is on the sunny side, the compressor has to work almost without interruption, which sharply increases Indesit electricity is not a constant value. It directly depends on the operating conditions and technical condition of the unit. One of the key factors is the room temperature. If the kitchen is located above a hot stove or is located on the sunny side, the compressor has to work almost continuously, which dramatically increases consumption kW.
The tightness of the door seals is the second critical point. Over time, the rubber profile dries out and no longer fits tightly to the body. Warm air penetrates through the resulting cracks, the sensors detect the increase in temperature and turn on the motor. As a result, the refrigerator hums more often than usual, and the counter spins faster.
Also worth it. take into account the volume of loaded products and their temperature. Loading the chamber with warm dishes after lunch requires significant energy expenditure to cool them. In addition, the location of the refrigerator affects heat transfer: if it is located close to the wall or furniture, the radiator on the back wall cannot effectively transfer heat.
Finally, the presence of the No Frost function or a static cooling system (drip) also dictates its own rules. data-i="75">require energy to operate fans and heating elements for defrosting, which makes them slightly more energy-intensive compared to classic models, although the difference in modern conditions is minimal.

Consumption table of popular Indesit models
For clarity, let’s look at the average electricity consumption for various series of refrigerators Indesit. Data are based on standard operating mode and may vary depending on the specific modification and year of manufacture.
| Refrigerator model | Energy efficiency class | Consumption per year (kWh) | Average per month (kWh) |
|---|---|---|---|
| Indesit DS 320 | A+ | 292 | 24.3 |
| Indesit EF 18 | A | 350 | 29.1 |
| Indesit C 132 G | A+ | 300 | 25.0 |
| Indesit NBS 20 | A++ | 255 | 21.2 |
The table shows that models with a higher energy efficiency class (A++) consume noticeably less energy per year. However, when purchasing, you should also take into account the initial cost of the device in order to understand whether the difference in price will pay off due to savings on electricity.
How the class is calculated. energy efficiency?
The class is defined as the ratio of actual energy consumption to the standard value. The standard value depends on the useful volume of the refrigerator and freezer compartments. The smaller this ratio, the higher the class (from G to A+++).
It is worth noting that older models released 10-15 years ago may have a class. B or C, and their consumption will be significantly higher than modern analogs. Replacing such a unit may become economically feasible in a few years.
How to independently calculate kilowatt consumption
If you want to find out the exact figure for your specific case, it is best to take measurements yourself. For this you will need a household wattmeter. (outlet meter), which can be purchased at electronics stores. This device is inserted into the outlet, and the plug of the refrigerator is already connected to it.
The measurement method is simple: leave the device connected for at least 24 hours. During this time, the refrigerator will go through several cycles of turning on and off, which will allow you to get the average value in kilowatt-hours per day, which can then be easily multiplied by. 30 days.
If you don’t have a wattmeter at hand, you can use the indirect method. Record the operating time of the compressor for one hour. For example, if the motor hummed for 20 minutes, then it worked for 1/3 of an hour. Multiply the compressor power (indicated on the tag, usually 150-300 W) by the operating coefficient.
☑️ Check before measurements
The calculation formula will look like this: Power (kW) × Operating time (hours) = Consumption (kWh). For a more accurate result, repeat the measurements at different times of the day, since at night, when the refrigerator is opened less often, its operation can be more economical.
Signs of increased energy consumption
Sometimes the refrigerator begins to “eat” electricity excessively due to hidden faults. The first sign is the continuous operation of the compressor. If you notice that the unit is humming almost without interruption, and rest pauses have become very short or have disappeared completely, this is a sure sign. problems.
The second sign is excessive heating of the housing on the sides or back. Although slight heating of the condenser is normal, hot surfaces may indicate that the heat removal system is not coping well and the compressor is overloaded. The third signal is the formation of ice or “fur coat” in the chamber even with proper defrost mode. data-i="106">⚠️ Attention: Constant operation of the compressor not only increases electricity bills, but also leads to rapid wear of the motor, which can result in expensive repairs or replacement of the unit.
⚠️ Attention: Constant operation of the compressor not only increases electricity bills, but also leads to rapid wear of the motor, which can result in expensive repairs or replacement of the unit.
It is also worth listening to the sounds of operation. Humming, knocking or clicking sounds may indicate problems with the start relay or the compressor itself. A faulty thermostat. may not give a command to turn off, causing the refrigerator to freeze all the way, consuming extra kilowatts.
Tips for reducing energy consumption
There are a number of simple but effective ways to reduce energy consumption without compromising the quality of food storage. First of all, check the temperature. The optimal temperature for the refrigerator compartment is +4...+5°C, and for the freezer -18°C. Setting the minimum values unnecessarily forces the equipment to work to the limit.
Make sure the door is sealed. Do a test with a sheet of paper: hold it with a door and try to pull it out. If the sheet is removed freely or with minimal effort, it means that the seal is worn out and requires replacement or treatment with silicone. This is a cheap way to restore efficiency.
Regular defrosting (for models with a drip system) and cleaning the back wall of dust will also work wonders. A layer of dust several millimeters thick acts as a heat insulator, interfering with the cooling of the condenser, which makes the compressor work longer.
Try not to load hot products into the chamber. Allow the soup or stir fry to cool to room temperature before storing. This will not only save electricity, but will also extend the life of other products lying nearby, which may deteriorate due to a sharp temperature change.
Frequently asked questions (FAQ)
Is it true that an empty refrigerator consumes more energy?
Yes, this is partially true. A refrigerator with food works more stable, since frozen or chilled food itself is a cold accumulator. The empty volume heats up faster when the door is opened, causing the compressor to turn on more often. However, it is also not worth filling the chamber to the point where air circulation is disrupted.
How many kilowatts does the Indesit refrigerator consume at startup?
At the moment of startup, the starting current of the compressor can be 3-5 times higher than the rated current. However, this impulse lasts for a fraction of a second and is practically not taken into account by the electricity meter in domestic conditions. The main consumption occurs during normal operation of the engine.
Does the presence of ice in the freezer affect consumption?
Of course. A layer of ice or snow more than 5 mm thick on the evaporator acts as a heat insulator. The cold is transferred into the chamber less well, the sensors do not detect a decrease in temperature, and the compressor works without stopping. Regular defrosting is necessary to save money.
Can an old Indesit refrigerator consume like a new one?
Theoretically, after replacing the seals, filling with freon and servicing the compressor, the old unit can get closer to the new performance. But wear of mechanical parts and outdated case insulation will still result in increased consumption compared to modern class models A++.
