Buying a Fridge Freezer: What to Consider When Choosing One, Comparing Energy Consumption and Reviewing Features

A fridge freezer should keep food neatly organised, reliably chilled and require as little effort as possible in everyday use. For families and larger households, appearance and total capacity are therefore not the only considerations. Usable storage space, energy consumption, noise level, door clearance and the split between the fridge and freezer compartments are all crucial.

Many offers look similar at first glance. However, some important differences only become apparent after purchase. The following advice will help you avoid common mistakes and choose a model that suits your living situation.

Three common pitfalls when buying a fridge freezer

1. Gross and net capacity are confused

A large appliance does not automatically mean plenty of usable storage space. Look at the net capacity, stated in litres separately for the fridge and freezer compartments. For example, a fridge freezer with a capacity of 355 litres might offer 249 litres of fridge space and 106 litres of freezer space. For planning your household storage, this split is more important than a large total figure in an advert.

Also check whether the internal layout suits the food you usually store:

  • several freezer drawers for storing food in portions,
  • adjustable glass shelves for bottles and tall containers,
  • door shelves for drinks and smaller packs,
  • a fresh-food compartment for fruit, vegetables, meat or fish.

2. The energy efficiency class alone is not enough

The EU energy label ranges from A to G. You should also consider the stated annual consumption in kWh per year. Two appliances in the same class may have different consumption figures depending on their size and technology.

For a realistic comparison, you should consider at least the following details together:

  • energy efficiency class,
  • annual consumption in kWh,
  • net capacity,
  • design and features,
  • expected operating time per day.

A more energy-efficient fridge freezer with a larger capacity may use more electricity overall than a smaller appliance, even if it has a better rating on the label. It is therefore best to compare models of a similar size and with similar usage patterns.

3. Dimensions and door clearance are underestimated

Before buying, measure the space where the appliance will stand, the route it will take during delivery and the area required to open the doors. Height, width and depth are not the only relevant measurements. Also consider:

  • clearance from the wall on the hinge side,
  • space needed to open drawers fully,
  • the width of doors, corridors and staircases,
  • ventilation clearances specified in the instruction manual,
  • the door opening direction and whether the hinges can be reversed.

A freestanding fridge freezer with a 90-degree door opening may be suitable for compact kitchens. A side-by-side fridge freezer or a French-door fridge freezer is usually considerably wider. These designs often provide wide shelves and compartments, but they also require a correspondingly spacious installation area.

Important technical specifications compared directly

NoFrost and separate cooling circuits

A NoFrost fridge freezer actively removes moisture produced during cooling and reduces ice build-up in the freezer compartment. Total NoFrost systems are designed to eliminate the need for regular manual defrosting. This saves time, but it does not replace cleaning the seals, drawers and interior surfaces.

Two separate cooling circuits can regulate the temperature of the fridge and freezer compartments independently. Some models also reduce the exchange of odours between the two areas. Check whether the NoFrost function actually applies to both compartments.

Noise level and compressor

A quiet fridge freezer is particularly important in open-plan kitchens or small flats. Noise levels are given in dB(A). Even a difference of a few decibels can be noticeable in everyday use, although perceived noise also depends on the floor, clearance from walls and operating conditions.

A fridge freezer with an inverter compressor adjusts its output to the cooling demand rather than operating solely through fixed on and off cycles. Even so, pay attention to the specific dB figure and annual consumption. Product specifications, for example, may list values ranging from 32 to 39 dB.

Fresh-food compartments and flexible zones

A fridge freezer with a fresh-food compartment can make it easier to organise different types of food. The key consideration is the type of temperature or humidity control actually provided. Terms such as FreshZone, VitaFresh, FreshShield and HarvestFresh refer to brand-specific features; their functions should be checked against the technical description and instruction manual.

A switchable Multi-Zone is useful when your requirements change throughout the year. Depending on the model, it can be used as either a fridge or freezer compartment. This is practical for larger shops, but it requires careful planning of how you store your food.

Fridge freezer FAQ

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

This depends on how often you shop, how much food you store and your freezer requirements. For several people, around 300 to 400 litres of net capacity may be suitable. If you regularly store multipacks, frozen meals or drinks, you should also look for sufficient freezer capacity and wide drawers.

Is NoFrost worthwhile in a fridge freezer?

NoFrost reduces ice build-up and the effort required for manual defrosting. This feature is particularly useful if you use the freezer drawers regularly. However, check whether NoFrost is specified for the entire appliance or just the freezer compartment.

How quiet should a fridge freezer be?

According to product data, models with around 32 to 35 dB are considered comparatively quiet. This figure is particularly relevant for open-plan kitchens or kitchens that form part of a living area. Also ensure that the appliance is standing level, has sufficient ventilation and is positioned at an appropriate distance from walls, as these factors can affect operating noise.
