Buying a Fridge-Freezer: What Matters When It Comes to Size, Energy Consumption and Features

A fridge-freezer should store food neatly, keep it reliably chilled and require as little effort as possible in everyday use. For families and larger households, capacity, noise levels, energy consumption and the available floor space are particularly important. However, marketing terms such as “smart”, “inverter” or “Total NoFrost” do not automatically indicate that an appliance is the right choice.

Common Fridge-Freezer Buying Mistakes

1. Total capacity alone does not tell you much

A large fridge with, for example, 400 litres can be divided up in very different ways. Always check the figures for the fridge and freezer compartments separately. A household that cooks fresh food frequently may need more fridge space. If you store lots of frozen food, on the other hand, you should look for sufficient freezer capacity and a well-designed drawer layout.

The external dimensions are also important: an appliance with a capacity of 600 litres may be considerably wider and deeper than a conventional freestanding fridge-freezer. Side-by-side fridges in particular often require more than 90 centimetres of floor width.

2. “Energy efficient” is not determined by the compressor alone

A fridge with an inverter compressor can adjust its performance to the actual cooling demand. This can contribute to quieter operation and more consistent temperatures. However, the figure that matters for running costs is the stated annual consumption in kWh.

EU energy-efficiency classes for refrigeration appliances range from A to G. Compare the kilowatt-hours per year directly. A simple calculation is:

Annual consumption in kWh × your electricity tariff = estimated annual electricity costs

The actual costs depend on your electricity tariff, room temperature, how fully the appliance is loaded and how it is used.

3. NoFrost does not mean maintenance-free

A NoFrost fridge-freezer prevents manual ice build-up in the freezer compartment where suitable systems are used. This makes maintenance easier, but it does not replace regular cleaning of door seals, shelves, water containers or air channels. If the appliance has a water dispenser, you should also check whether it requires a mains water connection or uses a tank.

The Key Parameters to Check Before Buying

Capacity and layout

As a general guide, smaller households may manage with around 200 to 300 litres. Families often benefit from 350 to 450 litres. A 400-litre fridge or larger can be useful if you regularly store larger grocery shops. Very large households may want to consider multi-door or side-by-side models with more than 500 litres.

Also pay attention to:

  • Number and adjustability of the glass shelves
  • Size of the vegetable and fresh-food drawers
  • Number of freezer drawers
  • Freezing capacity in kilograms per 24 hours
  • Storage time during a power cut
  • Ratio of fridge to freezer capacity

Floor space, door opening and access route

Measure more than just the recess. Check doors, stairwells and corridors too. Make sure the appliance door can open fully and that drawers can be pulled out. A freestanding fridge-freezer with a reversible door offers greater flexibility. With larger appliances, you must also maintain the wall clearance and ventilation spaces specified in the operating instructions.

Noise levels and features

The noise rating in dB(A) is particularly relevant in open-plan kitchens or small flats. Models rated at 29 to 35 dB are listed as quiet in the product data; 37 to 40 dB may be more noticeable depending on the room acoustics. Compare the figures directly rather than relying solely on terms such as “whisper-quiet”.

Useful features include:

  • Total NoFrost or automatic defrosting
  • Separate cooling circuits
  • Fast cooling and fast freezing
  • Door-open alarm
  • Reversible door
  • App control and temperature alerts
  • Water dispenser with a tank or mains water connection

An app is most useful when it provides practical notifications, such as an open door or a rise in temperature. It should not, however, be treated as a substitute for checking the appliance itself.

Fridge-Freezer FAQ

How many litres should a fridge-freezer have for a family?

This depends on your shopping habits and freezer requirements. For several people, 350 to 450 litres is often suitable. If you freeze supplies or shop less frequently, you may need a model with more than 500 litres. The specific division between fridge and freezer compartments is what matters.

How long does a fridge-freezer last?

Its lifespan depends on build quality, usage, ventilation and maintenance. Regularly cleaning the door seals, keeping the air channels clear and choosing a suitable installation location all help support reliable operation. If you notice unusual noises, continuous operation or reduced cooling performance, you should contact customer service.

How much does it cost to run a fridge-freezer?

For a realistic estimate, multiply the stated annual consumption by your electricity price per kilowatt-hour. An appliance using 150 kWh per year would cost around 52,50 Euro in annual electricity costs at a tariff of 0,35 Euro per kWh. Actual consumption may vary depending on room temperature and usage.
