Washer-Dryer Buyer’s Guide: How to Choose the Right Appliance

A washer-dryer is the ultimate space-saving 2-in-1 solution for any home that lacks the room for two separate appliances. Instead of placing a washing machine and a dryer side-by-side, a single unit handles both tasks. However, the market is filled with a wide variety of models featuring different capacities, technologies, and functions. This guide is designed to help you understand these features and make an informed decision when you're ready to buy a washer-dryer. We'll introduce a selection of appliances tailored to different needs.

What to Look for When Buying a Washer-Dryer

Choosing the right appliance depends on your individual needs. Three key criteria will help guide your decision: capacity, efficiency, and features.

1. Capacity: From Compact to Large-Load Models

The load capacity, measured in kilograms (kg), is one of the most important selection criteria. Note that washer-dryers always list two values: a higher capacity for washing and a lower one for drying. This is because laundry needs more space in the drum to tumble freely and dry effectively.

  • Compact Washer-Dryers (up to 3 kg wash / 1.5 kg dry): Ideal for single-person households, small apartments, or as a secondary appliance for special items like sportswear or baby clothes.
  • Standard Size (7–9 kg wash / 4–6 kg dry): A great choice for couples or small families with a regular amount of laundry.
  • Large-Capacity Washer-Dryers (10 kg+ wash / 7 kg+ dry): Recommended for large families or households that frequently wash bulky items like duvets.

2. Energy Efficiency and Noise Level

The running costs of a washer-dryer are primarily determined by its energy and water consumption. The EU Energy Label provides this information. Since 2021, new, stricter classes from A (very efficient) to G (less efficient) have been in effect. A Class A energy-efficient washer-dryer for the wash cycle is a worthwhile investment for long-term savings.

Another factor is the operating noise level, measured in decibels (dB). A quiet washer-dryer is particularly beneficial if the appliance is located in the kitchen or an open-plan living area. Models with a noise level below 72 dB during the spin cycle are considered relatively quiet.

3. Smart Features and Special Programmes

Modern appliances offer much more than just washing and drying. These features can make daily life significantly easier:

  • Smart Washer-Dryer: Wi-Fi-enabled models can be controlled via an app. You can start a cycle remotely, check its status, or receive notifications when your laundry is done.
  • Washer-Dryer with Steam Function: This feature refreshes clothes without a full wash and significantly reduces wrinkles, saving you time on ironing.
  • Automatic Load Sensing: The appliance detects the size of the load and automatically adjusts water and energy consumption accordingly.
  • Specialty Programmes: Cycles for sportswear, wool, allergy sufferers, or for reducing microplastics provide tailored care for different textiles.

Frequently Asked Questions (FAQ)

How effective is the drying performance of a washer-dryer?

Modern washer-dryers have made significant advancements in recent years. Their drying performance is generally good, as long as you don't exceed the maximum drying capacity. For best results, it's important to use a high spin speed before drying and to avoid overloading the drum, allowing air to circulate freely.

Are washer-dryers more expensive to run than separate appliances?

A combined wash-and-dry cycle tends to use more water and energy than a wash-only cycle in a standard washing machine. When compared to the total consumption of one wash cycle plus a separate drying cycle, the cost depends heavily on the efficiency of the appliances. A highly efficient washer-dryer can be quite competitive with moderate use, especially when you factor in the savings on the purchase price and space of a second appliance.

Which features are most useful in a washer-dryer?

The most practical features are those that simplify daily routines and improve laundry care. These include automatic load sensing to adjust consumption, a steam function to reduce wrinkles and refresh clothes, and smart control options via an app for greater flexibility. Special programmes for delicate fabrics or for reducing allergens can also offer significant value. Checking the results from a professional washer-dryer review can also provide helpful guidance.
