How Much Does a Fridge Really Cost in Electricity Each Year?

Posted on

Introduction

The refrigerator is one of the most used household appliances. It is plugged in as soon as we move in and often remains on for years. We constantly rely on it to preserve our food, drinks, and sometimes certain medications that require proper refrigeration. Yet, few people really wonder how much it costs in electricity each year. In this article, we will explore how a fridge works, how it consumes energy, and simple, concrete ways to reduce the bill. We will also see how to make the best choice when buying a new refrigerator. Throughout the following sections, you will discover many useful tips and tricks to optimize your energy consumption and save money in the long run.

Understanding How a Refrigerator Works

Before estimating electrical consumption and its cost, it is essential to quickly understand how a fridge works. It relies on a technology of compression-decompression of a refrigerant fluid. The compressor, often located at the back or below the unit, pressurizes a gas that liquefies. This fluid circulates in the walls to absorb the heat from the storage compartments. Then, it expels this heat outside via the condenser, keeping your food cool. This continuous cycle of compression and expansion requires electricity.

Even when the compressor does not run continuously (as it stops once the interior temperature is sufficiently cold), the refrigerator remains plugged in and consumes electricity to maintain this coolness. This consumption is therefore permanent, punctuated by peaks during the compressor's re-engagement phases.

Different Types of Fridges

The electrical cost of a refrigerator also varies depending on its technology and configuration. There are several major types of appliances, each with different characteristics.

  1. Table Top Refrigerator
    This is a compact model, often placed under a countertop. Its average capacity is 100 to 150 liters, and it is more suitable for small households or people living alone. Its consumption is relatively modest, although caution is needed regarding its energy class.

  2. Combined Refrigerator
    It combines a refrigerator and a freezer in one appliance, with the freezer often located at the bottom. These models are very common in families as they allow storing both fresh and frozen products. Their volume frequently exceeds 200 to 300 liters.

  3. American Refrigerator
    This type of fridge is characterized by a double vertical door, with the freezer on one side and the refrigerator on the other. It offers large storage space, sometimes accompanied by features like a fresh water or ice dispenser. Its larger dimensions often imply higher energy consumption.

  4. Built-in Fridge
    It blends into the kitchen decor and must meet specific dimensions. Its consumption mainly depends on its volume and energy class.

Understanding the Importance of Energy Class

For several years, household appliances have displayed an energy label allowing comparison of their efficiency. This label ranges from the most economical class (A, sometimes A++ or A+++) to the most energy-consuming (G). Even though the classification has recently evolved to simplify reading, the idea remains the same. A refrigerator in the best categories can consume 30 to 40 percent less electricity than an older or lower-end model. If you are hesitating between two fridges, a quick glance at their energy label will give you a concrete overview of their estimated annual consumption.

By opting for a more efficient appliance at the time of purchase, you can achieve substantial savings over several years. With the possible rise in electricity prices, a difference of a few dozen kilowatt-hours per year can quickly represent several tens of euros of avoidable expense over the appliance's lifespan.

How to Estimate Your Fridge's Annual Consumption

Manufacturer's Indicative Figures

Every refrigerator sold in stores or online must be accompanied by technical data indicating its electrical consumption in kWh per year. This data often refers to standardized test conditions (ambient temperature, filling rate, etc.). It gives a good idea of consumption if one adopts average usage. However, in practice, actual conditions differ, and real consumption may be slightly higher or lower than advertised.

The Importance of Ambient Temperature

A fridge installed in a warm room (sunny kitchen, poorly ventilated space, or near the oven) sees its compressor run more often. With the target interior temperature remaining the same, the appliance must work harder to compensate for the ambient heat. Consequently, consumption can rise.

Daily Use and Filling Rate

Methods to Measure Actual Consumption

If you want to know your appliance's exact consumption, you can use a wattmeter. This tool is placed between the wall socket and the fridge plug. It records the power consumed in real time and can calculate the total consumption over several days or weeks. This way, you get a clear overview of the exact energy expenditure. You can then compare this data to the kWh price to estimate your annual bill.

How Much Does a Fridge Cost in Electricity Over the Year?

Let's take some concrete examples to illustrate potential costs. Imagine your fridge consumes 200 kWh per year. If the kWh cost is 0.17 euros, then the annual bill will be 34 euros. For a larger (or older) refrigerator with a consumption of 350 kWh per year, it reaches 59.50 euros per year. Of course, these figures can vary depending on the rates charged by your electricity supplier and the energy class of your appliance.

Over time, this expense can represent a few hundred euros. Although it may seem modest compared to other bills, it is a recurring and unavoidable cost. If you are looking to save money at home, acting on your refrigerator remains an interesting and often underestimated lever.

Factors That Greatly Influence the Bill

To better understand what increases or decreases your fridge's consumption, here are the main criteria:

  1. The Age of the Refrigerator
    Older models do not incorporate the same temperature regulation technologies as recent appliances. Their insulation and compressor are often less efficient.

  2. Sizing
    An appliance too large for your household will be underutilized and operate less efficiently. Conversely, a fridge that is too small and constantly overloaded may struggle and consume more.

  3. Energy Class
    A fridge of class A or B will be more economical than an appliance of class D or E. It is increasingly wise to choose a high-performance appliance when purchasing to limit consumption in the coming years.

  4. Maintenance
    A poorly maintained fridge, with worn seals or a non-functional defrosting system, can consume more. Regular cleaning, checking seals, and defrosting if necessary are important to avoid energy losses.

  5. Room Temperature
    The higher the ambient temperature, the harder the appliance works to maintain the cold. Installing the fridge away from direct sunlight and heat sources can reduce the bill.

Tips to Reduce a Fridge's Consumption

Now that you know the determinants of electrical consumption, let's see how to optimize your refrigerator's use to make real savings.

1. Properly Set the Interior Temperature

Many people keep their food at a colder temperature than necessary. It is generally recommended to maintain the refrigerator between 4 and 5°C, and the freezer around -18°C. Any further decrease (for example, lowering the refrigerator to 2°C) leads to increased consumption.

2. Defrost Regularly

If your refrigerator does not have an automatic defrost mode, regularly check for frost formation. A layer of a few millimeters can significantly increase consumption. Defrost regularly to avoid this overconsumption.

3. Dust the Back of the Refrigerator

The coil at the back (or below) expels the heat extracted from the unit. If it is dirty, heat dissipation is poor, and the compressor runs more. Periodic cleaning (twice a year) with a cloth or soft brush is recommended.

4. Position the Fridge in the Right Place

Avoid placing the fridge near an oven, radiator, or very sunny window. If possible, install it in a ventilated area. Also, follow the manufacturer's recommendations regarding the distances to leave around for good air circulation.

5. Limit Door Openings

Every time you open the door, cold air escapes, and warm air enters. This imposes additional energy expenditure to restore the temperature. Try to group fridge access phases and do not leave the door open too long.

6. Do Not Block Ventilation Grilles

Some models have ventilation openings on the sides or back. Blocking these vents with objects or furniture may overheat the appliance or reduce its ability to disperse heat.

7. Check Door Seals

Damaged or misaligned seals let cold air escape. Check their condition by sliding a piece of paper: if it falls easily when closing the door, it is time to replace or reposition the seals.

8. Let Dishes Cool Before Refrigerating

If you place leftover meals still hot in the fridge, the interior temperature rises, and the appliance must work longer. Let them cool to room temperature first, then store them in the refrigerator.

When and How to Renew Your Refrigerator

It may be worthwhile to replace an older fridge, even if it is still operational. Although this may seem contradictory to the trend of reuse, an energy-consuming model can end up costing more in the long run than a recent, less consuming fridge.

  1. Evaluate the Appliance's Age
    Beyond 10 years, fridges may show signs of weakness in terms of energy performance. It is possible to estimate its consumption using a wattmeter for a more informed decision.

  2. Compare Energy Classes
    As mentioned earlier, energy labels guide you in choosing a replacement model. Choosing a high energy class (A or B) guarantees savings on the monthly bill.

  3. Consider the Necessary Capacity
    Buying a large capacity combined or American fridge is not necessarily the best choice for a two-person household. It is better to opt for a smaller appliance, but suited to your needs, to avoid energy waste.

  4. Think About Additional Functions
    Some refrigerators offer features such as the No Frost option, which prevents frost formation, and temperature-adjustable compartments for cheese or meat. These functions can optimize conservation while limiting consumption if used properly.

  5. Take Advantage of Promotions or Energy Bonuses
    In some countries, there are schemes to encourage the purchase of more efficient equipment (bonuses, aids meeting certain criteria). Find out if you can benefit from these advantages.

Focus on Environmental Impact

The electrical consumption of a refrigerator is not limited to the electricity bill. Each kilowatt-hour produced emits a certain amount of CO2, varying according to your country's energy mix (nuclear, coal, wind, etc.). Choosing a less energy-consuming model also means reducing your carbon footprint. Moreover, a new generation fridge will often use less polluting refrigerant gases than older appliances.

By extending your appliance's lifespan as much as possible, you limit the impact related to the production of new equipment. It is therefore about finding a balance between durability, performance, and environmental respect.

Common Mistakes to Avoid

  1. Placing the Fridge Against a Wall with a Heating Pipe
    This area is often warmer, forcing the appliance to make extra effort.

  2. Filling the Freezer Randomly
    Stacking products haphazardly limits cold air circulation. It is advisable to store and organize frozen foods for optimal cooling.

  3. Using the Super-Cooling Function Continuously
    This option (present on some fridges) is intended to quickly lower the temperature in case of a heavy load of fresh food. Forgetting it on permanently can increase the bill.

  4. Neglecting Minor Breakdowns
    A suspicious noise or a slightly cracked seal can signal a problem that will eventually increase consumption or cause a more serious breakdown.

Example of Profitability Calculation for Replacement

Let's take a numerical example to evaluate the relevance of investing in a more efficient refrigerator:

Suppose the new fridge costs 500 euros. If you save 34 euros per year, it will take about 15 years to recoup this purchase on the electricity bill alone. Of course, many other criteria can influence this calculation (likely increase in electricity prices, reliability, user comfort, ecological footprint).
