Buyer's Guide to Refrigerators and Freezers

Purchasing a new refrigerator or freezer is a major decision for any household. But with countless models, technical specs, and marketing promises, it's easy to feel overwhelmed. Hasty purchases often lead to appliances that prove too noisy, energy-intensive, or simply impractical in daily life. This guide will help you understand the crucial criteria and avoid common pitfalls.

Three Common Mistakes When Buying Refrigerators and Freezers

Before we dive into the technical details, let's look at three widespread misconceptions that often lead to disappointment.

1. Misinterpreting Energy Efficiency: Since 2021, a new scale from A (very efficient) to G (less efficient) has been in effect. A modern appliance with a Class E rating can be more economical than an old model labelled A++. Relying solely on the letter grade, without checking the actual annual power consumption in kWh, often leads to unexpectedly high running costs.
2. Underestimating Noise Levels: An appliance advertised as "quiet" can still be perceived as disruptive in an open-plan kitchen or a small apartment. The decibel (dB) rating is often ignored, even though just a few decibels can mean the difference between being barely perceptible and a constant hum.
3. Believing NoFrost is Always Necessary:NoFrost technology prevents ice build-up and eliminates the need for manual defrosting—a clear convenience benefit. However, for a secondary appliance in the basement, like a freezer chest that is rarely opened, this feature isn't always essential and can unnecessarily increase both the purchase price and energy consumption.

What Really Matters: The Core Parameters in Detail

To make an informed decision, you should focus on three objective metrics that determine an appliance's true value.

1. Capacity and Form Factor: The Right Size for Your Needs

The first step is choosing the appropriate form factor and volume. The needs of a family household are fundamentally different from those of a single person or a camper.

• Fridge-Freezer Combination: The standard solution for most kitchens. It combines refrigerator and freezer sections in one unit and is available in various sizes and layouts.
• Chest Freezer or Upright Freezer: Ideal if you need extra freezer space for bulk shopping or harvesting from your own garden. A freezer chest is often more energy-efficient, as less cold air escapes when it's opened. A small freezer or a mini freezer is suitable for small households or as a supplementary unit.
• Counter-Top Refrigerator with Freezer Compartment: A compact solution for offices, student dorms, or as a secondary appliance.
• Portable Refrigerator / 12V Compressor Cooler: Indispensable for camping, truck drivers, or boat owners. These devices run on a vehicle's electrical system (12V/24V) and reliably keep food cool on the go.

As a rule of thumb, plan for about 50–80 litres of usable capacity per person in the household.

2. Energy Efficiency Class and Annual Consumption (kWh/annum)

The energy efficiency class provides an initial orientation, but the crucial figure is the annual energy consumption in kilowatt-hours (kWh/annum), found on the energy label. Multiply this value by your current electricity price per kWh to estimate the approximate annual running costs. This allows you to objectively compare whether a more expensive but more economical appliance will pay off in the long run.

3. Noise Emission in Decibels (dB)

The noise level of a cooling appliance is an often-underestimated factor for home comfort. Especially in open-plan kitchens or studio apartments, quiet refrigerators are essential.

• Below 35 dB: Considered very quiet and is generally barely audible. Ideal for open-plan kitchens and bedrooms.
• 36–40 dB: Corresponds to a soft whisper or a quiet library. Acceptable in most living situations.
• Above 41 dB: Can be perceived as a disruptive hum in quiet environments. Better suited for enclosed kitchens or basements.

Key Advantage & Pros

4-star freezing performance for long-term storage, a reversible door for flexible placement, and a good energy efficiency Class D.

Frequently Asked Questions (FAQ)

What do the new energy efficiency classes for refrigerators mean?

The scale, in effect since March 2021, ranges from A to G. It is stricter than the old scale (A+++ to D). An appliance with a new Class E or F rating can be more efficient than an old appliance rated A++. For an objective comparison, the annual electricity consumption in kWh shown on the label is always the decisive factor.

How quiet is a "quiet refrigerator" really?

An appliance is considered very quiet if its noise emission is below 35 dB. This is barely audible and ideal for open-plan living areas. Models between 36 and 40 dB are also still very quiet. Pay attention to this value if the appliance will be placed near you.

Do I absolutely need a NoFrost function?

NoFrost is very convenient as it prevents ice from forming in the freezer section, making manual defrosting obsolete. This is particularly advantageous for frequently used fridge-freezers in the kitchen. For a rarely opened freezer chest in the basement, you can forgo this feature to save on purchase and energy costs.
