Side-by-Side Refrigerator Buyer’s Guide: Avoid Costly Mistakes

Purchasing a new side-by-side refrigerator is a significant investment for any household. These appliances, often called American-style refrigerators, offer ample storage space and modern features. However, the market is filled with marketing claims that don't always deliver. Before you make a decision, it's crucial to understand the most common pitfalls that can lead to dissatisfaction and unnecessary costs.

  • The Capacity Trap: Manufacturers often advertise the gross volume, but the actual usable storage space (net capacity) is what truly matters. Poorly placed compartments or thick insulation can significantly reduce the usable space.
  • The Noise Level Misconception: A loud refrigerator can severely impact the quality of life, especially in open-plan kitchens. A difference of just a few decibels (dB) is clearly noticeable. Models without an inverter compressor are often louder and adjust their cooling power less efficiently.
  • The 'No Frost' Inaccuracy: Many appliances advertise "No Frost," but only a "Total No Frost" system completely prevents ice build-up in both the fridge and freezer sections. Partial systems may still require manual defrosting.

What Really Matters When Making Your Choice

To avoid a bad purchase, you should base your decision on objective technical parameters. Three criteria are of central importance.

1. Correctly Evaluate Usable Capacity and Dimensions

A large family refrigerator should be adequately sized. As a rule of thumb, plan for about 100 litres of usable capacity per person in the household. A family of four, therefore, needs an appliance with at least 400 litres of total usable capacity.

Always pay attention to the net usable capacity in the manufacturer's specifications. Before buying, precisely measure the intended installation space. Consider not only the height, width, and depth of the appliance but also the necessary clearance from the wall for adequate ventilation (usually 5–10 cm on the sides and back) and the space needed to fully open the doors.

2. Understand Energy Efficiency and Running Costs

A refrigerator runs 24 hours a day, 365 days a year, making its running costs a crucial factor. The EU energy label, valid since 2021 with classes from A (very efficient) to G (less efficient), provides clear guidance.

The decisive value is the annual energy consumption in kilowatt-hours (kWh/year), which is stated on the label. An energy-efficientinverter compressor significantly contributes to reducing consumption. It continuously adjusts its performance to the cooling demand, which leads to fewer temperature fluctuations and protects the motor.

3. Weighing Noise Emissions and Convenience Features

For open-plan kitchens, a quiet fridge-freezer is essential. Appliances with a noise emission of under 40 dB are considered quiet. Models around 35 dB are barely perceptible.

Modern convenience features significantly enhance everyday usability:

  • Total No Frost: This technology prevents ice formation throughout the entire appliance, making manual defrosting obsolete. It is a standard feature in high-quality side-by-side models.
  • Fridge-freezer with a water dispenser: There are two variants here. Models with a plumbed-in connection offer an unlimited supply of chilled water and ice but require installation. Appliances with an integrated water tank are more flexible in their placement.
  • Multi-Airflow System: Ensures an even distribution of cold air on all levels, which keeps food fresh for longer.

## Frequently Asked Questions

How much space does a side-by-side refrigerator need?

In addition to the appliance's dimensions (typically around 180 cm high, 91 cm wide, 70 cm deep), you must plan for extra space for ventilation. Keep at least 5 cm of clearance from the wall on the sides and at the back to prevent the compressor from overheating. Also, plan for enough room in front of the appliance to allow the doors to open completely.

What does "Total No Frost" mean in an American-style refrigerator?

"Total No Frost" is a circulated air cooling system that reduces and removes humidity from the entire appliance—both the fridge and freezer sections. This prevents the formation of ice and frost from the outset. You will never have to manually defrost the appliance again, which saves time and ensures consistently high energy efficiency.

What are the annual electricity costs for an energy-efficient side-by-side refrigerator?

The costs depend on the energy efficiency class, the specific consumption of the model, and your electricity rate. A Class D appliance with a consumption of approx. 270 kWh/year will incur annual costs of about €95 at an electricity price of 35 cents/kWh. In comparison, a very efficient Class B model with 175 kWh/year would only cost around €61. Investing in a higher efficiency class can pay off over the lifespan of the appliance.
