Buying a Fridge: Designs, Energy Consumption and Suitable Models Compared

A fridge is one of the appliances that runs every day for many years. Choosing one that suits your kitchen, household size and shopping habits is therefore particularly important. Marketing terms such as “large”, “quiet” or “energy-efficient” do not tell you much on their own. The key factors are usable capacity, energy consumption, noise level, dimensions and features.

Common pitfalls when buying a fridge

1. External dimensions and usable capacity are confused

A large fridge can take up a lot of space without making the best use of the available interior. So, do not just check the width. Also look at the usable capacity in litres and how the space is divided between the fridge and freezer compartments. A fridge freezer with a capacity of 250 litres may be sufficient for a couple, while families will often need at least 300 litres or more.

Depth is also important: the CHiQ JR318WSD model is 63.5 cm deep, for example, allowing it to stand in front of a kitchen unit run. You must also take the door opening radius and ventilation clearances into account.

2. Energy efficiency is judged solely by the letter rating

The EU energy label ranges from A to G. The energy efficiency class should always be considered alongside the annual consumption in kWh. A larger class C appliance may use more electricity than a smaller class E fridge, but it also offers considerably more usable capacity.

Examples from the product data: the homeX CFSN2531C-S is specified at 141 kWh per year, while the Gorenje NRK620CA2XL4 is rated at 158 kWh. For large appliances such as the LG GMF961EV6C, the stated figure is 230 kWh per year with 645 litres of usable capacity. Actual costs depend on your electricity tariff and how the appliance is used.

3. Convenience features are equated with low maintenance

According to the product information, a No Frost fridge prevents ice from forming in the freezer compartment, reducing the need for manual defrosting. However, this does not mean that cleaning, caring for the seals and checking the ventilation can be neglected.

A fridge with a water dispenser or ice dispenser requires additional care. Water tanks, dispensing areas and, where applicable, filters must be cleaned or replaced in accordance with the instruction manual. Also check whether a mains water connection is required or whether a tank needs to be filled manually.

The most important selection criteria

Capacity and layout

As a general guide, the required usable capacity can be estimated based on household size:

  • Single-person households: compact fridge or model with around 100 to 200 litres
  • Couples: often well served by 200 to 300 litres
  • Families: around 300 to 500 litres, depending on shopping frequency
  • High-capacity users: large fridge, multi-door fridge or American-style fridge freezer with around 450 litres or more

The layout is just as important. A 70/30 fridge freezer provides more space for fresh food, while a model with a large freezer compartment is suitable for storing larger quantities. French-door fridges and multi-door models make it easier to organise the interior, but require more floor space.

Noise level

Noise levels are given in dB(A). Even a difference of just a few decibels can be noticeable in an open-plan living area. The product data lists, for example, 35 dB for the Gorenje NRK620CA2XL4, 37 dB for the CHiQ JR318WSD and 39 dB for the homeX CFSN2531C-S.

Noise emissions also depend on the installation, the floor and the operating phase. A freestanding fridge should be level and positioned with sufficient clearance from the wall to prevent vibrations from being amplified.

Design, door hinge and space requirements

Before buying, measure:

  1. Recess or installation width
  2. Height up to the wall units
  3. Depth, including ventilation clearance
  4. Space required for open doors and drawers
  5. Width of doorways, staircases and lifts for delivery

A reversible door hinge is practical in small kitchens. With an American-style fridge freezer or French-door fridge, both doors should be able to open fully. Appliances with a water dispenser also require you to consider installation and cleaning.

Practical buying and installation tips

  • After transport, leave a freestanding appliance standing upright. The exact waiting time depends on the instruction manual.
  • Position the fridge level and leave the specified clearances unobstructed to allow heat to escape.
  • For larger shopping trips, use the Fast Freeze or Super Cool functions if available.
  • Do not overfill the compartments, so that air can continue to circulate.
  • For an appliance intended for a cellar, garage or utility room, check the stated climate class and permitted ambient temperature range.
  • In addition to the purchase price, compare annual electricity consumption, delivery conditions and disposal options.

Frequently asked questions about fridges

How much electricity does a fridge use?

Consumption depends on the size, energy efficiency class, ambient temperature and how the appliance is used. For a fair comparison, use the kWh per year figure shown on the energy label. Multiply it by your electricity price per kilowatt-hour to calculate the approximate annual running costs.

How long does a fridge last?

A specific service life cannot be guaranteed. It is influenced by factors including the compressor, seals, usage, cleaning and installation conditions. Regular cleaning, unobstructed ventilation openings and a suitable temperature help reduce avoidable strain. Warranty and service conditions should be checked before buying.

How much clearance does a freestanding fridge need?

The required clearance is specified in the relevant installation instructions. In general, the compressor and heat exchanger need sufficient space for air to circulate. Doors and drawers must also be able to open fully. In a small kitchen, it is therefore not just the appliance dimensions that matter, but also the actual space needed to move around it.
