The refrigerator Bosch is one of the most energy-intensive appliances in the house, operating 24/7. But exactly how many kilowatts does it “eat” in a month? The answer depends on the model, energy class, volume and even how you use it. In this article we will analyze real consumption popular series Bosch (for example, KGE36AW20R, KGN39VL35R, KIV87VS30R), compare them with GOST standards and show how to reduce lighting costs without compromising the safety of products.
Many users are faced with discrepancy between the figures declared by the manufacturer and the actual meter readings. Why is this happening? The fact is that laboratory tests are carried out under ideal conditions (+25°C in the room, the door does not open, the chambers are 50% full), whereas in real life the refrigerator operates under constant load. We analyzed data from equipment passports, owner reviews and technical reports to give an accurate answer.

Energy efficiency classes of Bosch refrigerators: what do the letters A+++, A++ and others mean
Since 2021, the EU has a new energy efficiency scale for household appliances - from A (the most economical) to G (the least efficient). However, there are still some on the market. models Bosch with outdated markings (A+++, A++ etc.) Let's figure out how this affects consumption.
Refrigerators with markings A+++ (for example, Bosch KAN92VI30R) consume less. data-i="75">than class models 40–50% less electricitythan class models A+. The difference between A++ and A+++ can reach 100–150 kWh per year - this is about 500–700 rubles of additional costs with an average tariff of 5 rubles/kWh.
Important: from March 1, 2021, manufacturers are required to indicate energy consumption according to the new standard EN 62552, which takes into account real operating conditions (for example, opening the door 5 times a day). Old labels (A+++) often overestimated the efficiency by a factor. 15–20%.
- 🔋
A+++(until 2021) ≈AorB(on the new scale) - 🔌
A++≈CorD - ⚡
A+and below ≈E–G(the most voracious)
⚠️ Attention: If your refrigerator Bosch was produced before 2021, its actual consumption may be higher than indicated on the label. Check the data with the passport or sticker on the back wall (look for the line Energy consumption per year).
How much electricity does a Bosch refrigerator consume: table by model
The following is a calculation for popular series Bosch based on manufacturer data and owner reviews. The numbers are indicated for standard conditions: room temperature +25°C, the door opens 5-7 times a day, the chambers are full. 60%.
| Model | Energy efficiency class | Volume (l) | Consumption per year (kWh) | Consumption per month (kWh) | Cost per month (at 5 rubles/kWh) |
|---|---|---|---|---|---|
| Bosch KGE36AW20R | A+++ (≈ B) |
309 | 203 | 17 | 85 rubles |
| Bosch KGN39VL35R | A++ (≈ C) |
366 | 273 | 23 | 115 rubles |
| Bosch KIV87VS30R | A+++ (≈ A) |
287 | 185 | 15 | 75 rubles |
| Bosch KAD92SB30R | A++ (≈ D) |
523 | 380 | 32 | 160 rubles |
| Bosch KGN33NW15R | A+ (≈ E) |
311 | 410 | 34 | 170 rubles |
Please note: models with a system NoFrost (for example, Bosch KAD92SB30R) consume 10–15% more electricity than analogues with drip defrosting (Bosch KGE36AW20R), but do not require manual defrosting. Also, the consumption is affected by the presence of freshness zones (for example, VitaFresh in the series KGN), which maintains a temperature of 0°C and increases the load on the compressor.
For comparison: an average class refrigerator with a volume of 300–350 liters consumes A+++ volume 300–350 l consumes 150–250. kWh per year, while models of 10 years ago consume up to 500–600 kWhThe difference in the cost of electricity can reach 2000–2500 rub/year.
What the actual electricity consumption depends on: 7 key factors
Even for two identical models Bosch electricity consumption can differ by 1.5–2 times. Here is what affects it:
- The room temperature. At +30°C in the kitchen, the refrigerator consumes. on 30–40% morethan at +20°C. The optimal range is
16–22°C. - Door opening frequency. Each opening increases the load on the compressor. In a family of 4 people, the door opens on average. data-i="132">Frequency of door opening 20–30 times a day.
- The degree of filling of the chambers. An empty refrigerator spends energy on cooling the air, and an overloaded one spends energy on maintaining the temperature in a dense mass of products.
- Temperature mode. Recommended settings:
- 🥶 Refrigerator compartment:
+4°C(not lower+2°C) - ❄️ Freezer compartment:
-18°C(for long-term storage)
- 🥶 Refrigerator compartment:
SuperCool or SuperFrost increase consumption by 1.5–2 times during activation.For example, if in your model Bosch KGN39VL35R set the temperature -24°C in the freezer instead of -18°C, the annual consumption will increase from 273 to 320–350 kWhAnd if the seal allows air to pass through, another +50 kWh will be added.
How to calculate the consumption of your Bosch refrigerator: step-by-step instructions
If you did not find your model in the table or want to clarify the data, use this method:
- Find the refrigerator passport. Look for the line
Energy consumption per year(annual consumption in kWh). For example, for Bosch KIV38X20 this 190 kWh/year. - Divide by 12to get the average monthly consumption:
190 kWh / 12 ≈ 15.8 kWh/month - Multiply by tariff. At a cost of 1 kWh = 5 rubles:
15.8 × 5 ≈ 79 rubles/month - Adjust to actual conditions:
- 🔥 Summer (+30°C): +30% →
15.8 × 1.3 ≈ 20.5 kWh - ❄️ Winter (+18°C): −10% →
15.8 × 0.9 ≈ 14.2 kWh - 🚪 Frequent opening (more than 10 times/day): +15%
- 🔥 Summer (+30°C): +30% →
For accurate measurements, use wattmeter (connect the refrigerator through it for 24 hours). For example, the device Robiton PM-1 will show real consumption taking into account all load peaks. According to reviews, the difference between the passport data and actual measurements can reach 25%.

How to reduce the electricity consumption of a refrigerator Bosch: 9 working methods
Even if you have a class model A+++, actual consumption can be reduced by 20–30% without compromising the safety of products. Here are proven methods:
- ❄️ Optimize temperature. Place in the refrigerator
+4°C, in the freezer --18°C. Each degree lower adds 5–8% to flow rate. - 🔄 Thaw the refrigerator. Ice 5 mm thick increases consumption by 15%. Defrost the chambers every 6 months (for NoFrost - once a year).
- 🚪 Check the seal. If the rubber is cracked or deformed, replace it (cost for Bosch —from 1,500 rubles).
- 📦 Do not overload the chambers. Optimal fullness - 60–70%. Laying too tightly impairs air circulation.
- 🌡️ Keep the refrigerator away from heat sources. The minimum distance to the stove or battery is 50 cm. The temperature of the rear wall should not exceed
+45°C. - 💡 Disable unnecessary functions. Modes
SuperCool/SuperFrostEnable only for 2-3 hours before loading products. - 🔌 Use a voltage stabilizer. Jumps in the network force the compressor to work at the limit, increasing consumption by 10–15%.
- ☀️ Protect from direct sunlight. Even if the refrigerator is located near the window, use blinds or film.
- 🔄 Clean the condenser. Dust on the rear grille impairs heat transfer. Clean it with a vacuum cleaner once every 6 months.
Example of savings: if yours Bosch KGN39VL35R consumes 23 kWh/month, then after optimizing the temperature, defrosting and cleaning the condenser, the consumption will decrease up to 16–18 kWh is 250–300 rubles savings per year.
⚠️ Attention: Do not install the refrigerator Bosch in a niche without ventilation. The gap between the walls should be at least 5 cm at the back and sides. Otherwise, the compressor will overheat and electricity consumption will increase by 20–30%.
What to do if the refrigerator consumes too much?
If after all the measures the consumption remains high (more than 30 kWh/month for a class A+++ model), check:
1. Temperature sensor —if it breaks down, it can give incorrect signals to the compressor.
2. Compressor —wear or refrigerant leakage leads to constant operation of the motor.
3. Electronic board —failures in the firmware sometimes cause chaotic switching on/off.
In these cases, diagnostics are required at a service center (cost for Bosch —from 2000 rubles).
Comparison with other brands: who is more economical Bosch?
Refrigerators Bosch belong to the middle segment in terms of energy consumption. For comparison, let's take models of similar volume (300–350 l) and class A+++:
| Brand and model | Class | Consumption (kWh/year) | Deviation from Bosch (%). The main advantage |
|---|---|---|---|
| Bosch KGE36AW20R | A+++ |
203 | — |
| Liebherr CNef 4315 | A+++ |
180 | −11% |
| Samsung RB-30 J3200SA | A++ |
270 | +33% |
| LG GA-B409SLGL | A+++ |
210 | +3% |
| Indesit DF 4180 W | A+ |
350 | +72% |
As can be seen from the table, Bosch inferior in efficiency to premium brands (Liebherr), but outperforms budget ones (Indesit, Samsung middle segment). Main advantage Bosch — balance of price and energy efficiency, as well as the reliability of the compressors (service life - 10-15 years with proper operation).
If your goal is maximum savings, pay attention to models with inverter compressor (for example, Bosch KIV87VS30R). They are quieter and more economical than traditional ones by 20–25%, although they cost 10-15% more.
Frequently asked questions about the electricity consumption of Bosch refrigerators
🔹 How much electricity does a Bosch refrigerator consume in hour?
Average power of refrigerators Bosch — 100–200 W/hour, but the compressor does not work constantly, but in cycles (for example, it works for 15 minutes, rests for 30 minutes). Therefore hourly consumption usually is 30–80 W (depending on the model and conditions). For example, Bosch KGE36AW20R on average consumes about 50 W/hour.
🔹 Why does my Bosch refrigerator consume more than in the passport?
The reasons may be as follows:
- 🌡️ High room temperature (above +25°C).
- 🚪 Frequent or prolonged opening doors.
- ❄️ Thick layer of ice in the freezer (from 5 mm).
- 🔧 Malfunction of the compressor, temperature sensor or seal.
- ⚡ Voltage surges in the network (for example, with weak wiring).
For diagnostics, measure consumption with a wattmeter during the day.
🔹 Which Bosch refrigerator is the most economical?
The most energy efficient models Bosch (according to 2026):
- Bosch KIV87VS30R — 185 kWh/year (class
A+++, inverter compressor). - Bosch KGE36AW20R — 203 kWh/year (class
A+++, drip defrosting). - Bosch KAN92VI30R — 190 kWh/year (class
A+++, systemNoFrost).
They all belong to the series VarioStyle and are equipped with technology EcoSilencethat reduces noise and consumption.
🔹 Is it worth buying a Bosch refrigerator with NoFrost if it consumes more?
The system NoFrost increases electricity consumption by 10–15%, but eliminates manual defrosting. Calculate what is more profitable:
- 💰 Additional electricity costs: ~150–200 rubles/year.
- ⏳ Time saving: no need to defrost 1-2 times a year (3-4 hours each time).
- 🛠️ Service life:
NoFrostreduces wear of the seal and corrosion of metal parts.
If convenience is more important to you, NoFrost is justified. If the priority is saving, choose models with a drip system (for example, Bosch KGE36AW20R).
🔹 Is it possible to turn off a Bosch refrigerator at night to save money?
❌ Not It is recommended. When turned off for 8 hours:
- The temperature in the chamber will rise to
+10...+15°Cwhich will lead to spoilage of perishable products (meat, dairy products, ready meals). - The compressor will require 2–3 hours continuous operation to restore the mode, which will reduce savings to zero.
- Frequent switching on/off will shorten the service life of the motor.
Exception: if the refrigerator is empty and you are leaving for a long period (more than 2 weeks), you can turn it off after defrosting and drying it first.
