The refrigerator Indesit is one of the most energy-intensive appliances in the house, operating 24/7. Its consumption directly affects electricity bills, but few know how to accurately calculate consumption and what to look for when purchasing. In this article, we will look at the real numbers: how many kilowatts does a refrigerator spend Indesit per hour, day and month, how the energy efficiency class affects the cost of light, and what to do if the device “eats” too much.
You will learn not only the average values for popular models (from Indesit BIA 18 to Indesit EF 18), but and learn how to independently calculate consumption based on technical specifications. We will also reveal 5 little-known reasonswhy even a new refrigerator can spend 30% more energy than stated - and how to fix it without calling a technician.
Energy efficiency class: how it affects consumption
Since 2021, a new one has been in effect in the EU scale of energy efficiency classes - from A (the most economical) to G (the least efficient). For refrigerators Indesit classes A, B and Care relevant, and even within one class the spread of consumption can reach 20%. For example, a model Indesit ITF 118 W (class B) spends ~220 kWh per year, and a model Indesit EWT 26752 W (class C) - already 280 kWh.
It is important to understand: the class is assigned based on Energy Efficiency Index (EEI), which takes into account the volume of the chambers, climate class and even the presence of the function No Frost. Therefore, two refrigerators with the same class B can differ in actual consumption by 10–15%.
- 🔹 Class A: up to 180 kWh/year (savings up to 40% compared to class C). Example: Indesit ITR 5200 W.
- 🔹 Class B: 180–220 kWh/year. Popular models: Indesit BIA 18, Indesit BIAA 13.
- 🔹 Class C: 220–270 kWh/year. Often found in Side-by-Side: Indesit ESD 5510.
- 🔹 Class D and lower: over 270 kWh/year. Found in older models (before 2015) or refrigerators with a volume of >300 liters.
⚠️ Attention: If your refrigerator Indesit was produced before 2010, its energy efficiency class according to old standards (A+, A++) does not correspond to the new marks. For example, the old “A+”, according to the new rules, may turn out to be class C or even D.
How many kilowatts does an Indesit refrigerator consume per hour, day and month
The average consumption of a refrigerator Indesit depends on three key factors:
- Chamber volume: single-chamber (up to 150 l) waste 0.5–0.8 kW/day, two-chamber (200–300 l) - 0.8–1.5 kW/day.
- Climate class: models for hot climates (
T,ST) consume 10–15% more due to increased work compressor. - Operating mode: function
Super CoolorSuper Freezeincreases flow rate by 20–30%.
The table below shows real data for popular models Indesit (according to passport characteristics and user tests):
| Model | Energy efficiency class | Consumption per hour (kW) | Consumption per day (kW) | Monthly consumption (kW) |
|---|---|---|---|---|
| Indesit BIA 18 | B | 0.025–0.035 | 0.6–0.85 | 18–25 |
| Indesit BIAA 13 | B | 0.03–0.04 | 0.7–0.95 | 21–28 |
| Indesit ITF 118 W | A | 0.02–0.028 | 0.5–0.7 | 15–21 |
| Indesit EWT 26752 W | C | 0.04–0.055 | 1.0–1.3 | 30–39 |
| Indesit ESD 5510 (Side-by-Side) | C | 0.06–0.08 | 1.4–1.9 | 42–57 |
Critical error: many users multiply the passport annual consumption by the tariff to get the monthly cost. This is not true! Annual data is calculated under ideal conditions (temperature +25°C, door opens 5 times a day). In reality, consumption may differ by ±30%.
How to calculate the cost of electricity for a month
The calculation formula is simple:
(Consumption per day, kW) × 30 days × (tariff for 1 kWh, ₽) = Cost per monthExample for model Indesit BIA 18 (0.7 kW/day) at a tariff of 5.38 ₽/kWh (Moscow, 2026):
0.7 × 30 × 5.38 = 113 ₽/monthBut there are nuances:
- 📌 Tariffs differ by region. In St. Petersburg - ~4.5 ₽/kWh, in Krasnodar - ~3.8 ₽/kWh.
- 📌 In summer, consumption grows by 15–20% due to the heat (the compressor works longer).
- 📌 If the refrigerator is old (10+ years), its actual consumption may exceed the passport value by 1.5–2 times.
⚠️ Attention: In some regions they are valid multi-tariff meters (day/night). The refrigerator consumes energy evenly, so switching to such a tariff for its sake is unprofitable. But if you already have a two-tariff meter installed, keep in mind that ~60% of the consumption will be at night tariff (30–50% cheaper).
5 reasons why the Indesit refrigerator consumes more than normal
If your Indesit “winds” electricity beyond the rated values, check these factors:
- Incorrect temperature in the chambers. Optimal values:
- 🥶 Refrigerator compartment: +4…+5°C (not lower than +3°C, otherwise the compressor works without stopping).
- ❄️ Freezer compartment: −18°C (−20°C and below increases consumption by 10%).

How to reduce the consumption of an Indesit refrigerator: 7 working methods
Saving energy does not require purchasing a new appliance. Here's what you can do today:
- ⚡ Adjust the temperature. Install in the refrigerator +4°C, in the freezer - −18°C. Each extra degree below the norm increases consumption by 5%.
- ⚡ Thaw the refrigerator. Ice 5 mm thick impairs heat transfer by 20%. Defrost
No Frostonce every 6 months, drip systems - once every 1-2 months. - ⚡ Check the loading. A crowded refrigerator (especially the freezer) interferes with air circulation. Optimal loading is 70–80% of the volume.
- ⚡ Use the “Vacation” mode. If you are leaving for 1-2 weeks, turn on this mode (available in models Indesit with electronic control). It maintains +12…+15°C, saving up to 40% energy.
- ⚡ Install a voltage stabilizer. Voltage surges cause the compressor to wear out, increasing consumption. A stabilizer (from 2000 ₽) will pay for itself in 1–2 years.
- ⚡ Change the light bulb. Older models Indesit have incandescent lamps (25–40 W). Replace with LED (3–5 W) - save ~0.5 kW/month.
- ⚡ Disable unnecessary functions. For example,
Super Freezeor an ice maker (if you don’t use it). They add 10–15% to the consumption.
What to do if the refrigerator consumes too much even after all the measures?
If after optimization the consumption remains high (for example, >2 kW/day for a class B model), the problem may be:
- Faulty compressor (works without stopping).
- Freon leak (the refrigerator does not freeze well, but the motor hums constantly).
- Clogged capillary tube (sign: cold condenser, compressor hot).
In these cases, diagnostics by a specialist is required. The average cost of a repair is 2500–5000 ₽, but it will pay for itself in 6–12 months due to energy savings.
Comparison with other brands: who is more economical?
Refrigerators Indesit belong to the middle segment in terms of energy efficiency. For comparison:
- 🟢 Samsung and LG (class A): 10–15% more economical Indesit due to inverter compressors.
- 🟡 Atlant and Biryusa: approximately on the same level with Indesit, but often lose in freezing capacity.
- 🔴 Old ZIL or Minsk: consume 2-3 times more (up to 60 kWh/month).
- 🟣 Bosch i Liebherr (premium segment): 20–30% more economical, but also cost 2–3 times more.
If your budget is limited, Indesit is a reasonable choice: it is cheaper Bosch 30–40%, but not as “gluttonous” as budget Chinese brands (for example, Midea or Haier in the lower price segment).
⚠️ Attention: Energy efficiency data may vary depending on the year of manufacture of the model. For example, Indesit 2020 is 10–15% more economical than its 2015 counterparts due to updated compressors. Always check the energy efficiency class of a specific model in the technical data sheet.
FAQ: Frequently asked questions about the consumption of Indesit refrigerators
My Indesit refrigerator consumes 2 kW per day, although the data sheet indicates 0.8 kW. Is this the norm?
No, that's a lot. The reasons may be:
- Faulty thermostat (does not turn off the compressor).
- Freon leak (the refrigerator does not freeze well, but the motor runs constantly).
- Dirty condenser or problems in the system
No Frost.
First check the door seal and the temperature in the chambers. If it doesn’t help, call a specialist.
How much will it cost to operate an Indesit EF 18 refrigerator per month at a tariff of 4.5 ₽/kWh?
Model Indesit EF 18 (class B) consumes ~0.9 kW/day. Calculation:
0.9 × 30 × 4.5 = 121.5 ₽/monthIn summer, add 15–20% (up to 140 ₽).
Which Indesit refrigerator is the most economical?
Top 3 in energy efficiency (2023–2026):
- Indesit ITR 5200 W (class A, 150 kWh/year).
- Indesit ITF 118 W (class A, 160 kWh/year).
- Indesit BIA 18 NF (class B, but with an optimized compressor - 180 kWh/year).
All models have a system No Frost and electronic control.
Is it possible to turn off the refrigerator at night to save money?
No! When turned off:
- The temperature in the chambers will rise to room temperature in 4-6 hours.
- The compressor will require 2-3 hours of continuous operation to restore mode (energy consumption will be higher than during normal operation).
- Food may spoil (especially in the freezer camera).
Exception: if you are leaving for 1-2 days, you can turn off the refrigerator after defrosting and removing all the food.
How to check the real consumption of the refrigerator without a wattmeter?
Alternative methods:
- Turn off everything appliances in the apartment, except for the refrigerator. Record the meter readings for 1 hour - the difference will be the consumption.
- Use a smart socket with an energy metering function (costs from 800 ₽).
- Calculate on the meter: write down the readings in the evening, subtract them in the morning and multiply by 24 (for daily consumption).
Please note: the accuracy of these methods is ±10–15%.
