Choosing Energy-Saving Home Appliances

By the Joybuy Product Recommendation Officer, August 30, 2026

Purchasing new home appliances is a significant investment. With energy costs on the rise, efficiency is becoming a key consideration. However, the market is flooded with marketing promises and technical specs that often confuse more than they clarify. Many buyers fall into traps that lead to unnecessary expenses and frustration. This guide will help you cut through the noise and make an informed decision that pays off in the long run.

The 3 Most Common Mistakes When Buying Home Appliances

Before we dive into the key parameters, let's look at the common pitfalls to avoid.

1. The Low Price Fallacy: A low purchase price is tempting, but the true cost of an appliance is revealed over its lifespan. A cheap model with a poor energy efficiency rating can cost hundreds of euros more in electricity over the years than an initially more expensive, but more economical, appliance.
2. Superfluous "Smart" Features:Smart home devices are trendy, but not every smart function offers real value. App control that merely replaces the start button or complicated programmes that are never used often don't justify a higher price. Check whether the smart features will genuinely make your daily life easier or are just a tech gimmick.
3. The Underestimated Noise Factor: In modern open-plan living spaces, the operating noise of home appliances can become a major nuisance. A loud refrigerator or a spinning washing machine can significantly impact your quality of life. The decibel rating is often overlooked—a mistake you'll regret later.

What Really Matters: The Decisive Parameters

To make a smart purchasing decision, focus on objective and measurable criteria. These three aspects are essential for energy-efficient home appliances.

1. Decoding the EU Energy Label

Since March 2021, a new, stricter EU energy label with a scale from A to G has been in effect. The old "plus" classes (A+++, A++, A+) have been discontinued, making comparisons more transparent.

• Energy Efficiency Class A: Appliances in this class meet the highest standards and are extremely economical. They are the top choice if you want to save electricity at home in the long term.
• kWh Consumption: The label indicates energy consumption per 100 wash cycles (for washing machines) or per year (for refrigerators). Multiply this value by your current electricity price (in €/kWh) to estimate the annual running costs.
• Additional Information: Pictograms on the label provide other important data, such as water consumption, capacity, or the noise level during the spin cycle.

2. Noise Level in Decibels (dB)

Operating noise is a crucial comfort factor. Quiet home appliances are especially important in open-plan living areas or for overnight operation.

• Fridge-Freezer: Values below 38 dB are considered very quiet.
• Washing Machine: Pay attention to two values. The noise level during the wash cycle should be low, but the spin cycle value is more critical. Models below 72 dB during the spin cycle are a good choice for noise-sensitive households. An inverter motor (often called a DD motor or brushless motor) is a key contributor to quieter, lower-vibration operation.
• Tumble Dryer: Heat pump dryers are generally quieter than condenser dryers. A value around 65 dB is a good benchmark here.

3. Capacity and Useful Special Programmes

The appliance's size must match your household's needs. A unit that's too large wastes energy, while one that's too small leads to more frequent cycles.

• Buying a washing machine: A 6-7 kg capacity is sufficient for singles or couples. Families are better served with 8-10 kg.
• Refrigerator: As a rule of thumb, plan for 50-70 litres per person in the household.
• Useful Programmes: Features like a steam function (Steam Wash) can reduce ironing and allergens. Quick wash programmes (e.g., 15 minutes) are practical for lightly soiled laundry. For a washer-dryer, a non-stop wash and dry cycle for small loads (e.g., in 60 minutes) is a useful feature.

Frequently Asked Questions (FAQ)

1. Is a washer-dryer worth it compared to two separate appliances?

A washer-dryer is an excellent space-saving solution, especially in apartments without a separate utility room. Modern units offer good washing performance. However, it's important to note that the drying capacity is usually smaller than the washing capacity, and a combined cycle takes longer than two separate processes. For households that only dry laundry occasionally and need to save space, it's a very good option.

2. How important is an inverter motor in a washing machine or refrigerator?

An inverter motor (also known as a brushless DC motor or Direct Drive motor) is an essential feature of high-quality, energy-efficient home appliances. Unlike conventional motors, it operates without brushes, which reduces wear and tear and increases its lifespan. The benefits include significantly quieter operation, fewer vibrations, and higher energy efficiency, as the motor speed is seamlessly adjusted to the current load.

3. How much electricity does an Energy Class A appliance really use?

The exact consumption depends on the appliance type. For an Energy Class A washing machine like the TCL FP1210WA0, consumption is around 51 kWh per 100 cycles. Assuming an electricity price of €0.30/kWh, this results in a cost of only about €15.30 for 100 washes. A Bosch home appliance like the WQB245B40 heat pump dryer (although classified as Class B here, the principle is the same) uses 110 kWh per 100 cycles according to its label, which corresponds to a cost of about €33. Comparing these figures on the energy label is the most objective way to estimate long-term running costs.
