Buying a fridge: compare designs, energy consumption and suitable models correctly

A new fridge should store food reliably, fit into your kitchen and provide predictable running costs for many years. However, some common purchasing decisions can lead to unnecessary hassle later on: the appliance may not fit through the door, the noise may be distracting in an open-plan living area, or the actual storage capacity may not be sufficient for your household.

These pitfalls are particularly common:

  • Confusing external dimensions with usable capacity: A large front does not automatically mean lots of usable storage space. The stated litre capacity of the fridge and freezer compartments is what matters.
  • Judging energy efficiency solely by the letter: EU energy classes range from A to G. For running costs, the stated annual consumption in kWh is also relevant.
  • Treating No Frost as an all-purpose solution: A No Frost fridge saves you from manually defrosting the freezer compartment. However, it does not replace regular cleaning and still requires sufficient air circulation.

Which fridge parameters matter before you buy

1. Usable capacity and layout

For one person or an office, a mini fridge with around 80 to 100 litres may be sufficient. Households of two to three people often need a fridge-freezer with a capacity of around 200 to 300 litres. Families should look beyond the total capacity and consider the layout too: a large freezer compartment is of little use if you mainly store fresh food.

A fridge with a freezer compartment or a conventional fridge-freezer is more space-efficient for many homes than two separate appliances. However, anyone who regularly freezes large quantities may find an additional freezer useful.

2. Energy consumption and noise level

The energy efficiency class is shown on the EU energy label. You should also compare the annual consumption in kWh. A simple guide to running costs is:

Annual consumption in kWh × your electricity price per kWh = approximate annual energy cost

Actual consumption depends on factors including room temperature, how full the appliance is and how often the door is opened. For open-plan kitchens and studio flats, the noise level in dB(A) is also important. Several appliances list figures of around 37 to 40 dB(A) in their product details, which may be suitable for open-plan layouts. However, how loud an appliance seems depends on its position and the acoustics of the room.

3. Dimensions, door opening and installation location

Do not just measure the alcove. Also check:

  • The appliance’s width, height and depth
  • The route through the front door, hallway and stairwell
  • Space for open doors and pulled-out drawers
  • Clearance from the wall and adjacent furniture
  • Ventilation clearances specified in the instruction manual

A side-by-side fridge or French-door fridge offers plenty of storage space, but usually requires more floor space. Also check whether the doors can be reversed. For a garage or cellar, the stated climate class or permitted ambient temperature range is also important. Not every appliance is suitable for unheated rooms.

Other fridge designs at a glance

A wine fridge is designed for storing bottles at specific temperature ranges, but it cannot replace a fully equipped household fridge. A mini fridge may be sufficient for drinks in an office or guest room. If you need plenty of space, only choose a side-by-side fridge or French-door fridge if its footprint, door width and energy consumption suit your living situation.

For every model, focus on the product details rather than general marketing claims. Also consider whether you genuinely need a water connection, ice dispenser or app functions in everyday use. Extra features can make installation and cleaning more complicated.

Fridge FAQs

How many litres should a fridge have per person?

There is no fixed rule. As a rough guide, singles may manage with a smaller appliance, while couples and families can benefit from a larger fridge-freezer. Shopping habits, how much food you keep in stock and the desired freezer capacity are the key factors.

How can you reduce a fridge’s electricity consumption?

Do not place the appliance next to a radiator or cooker, allow hot food to cool down first and keep the ventilation areas clear. Keeping the fridge appropriately filled helps maintain a stable temperature. When comparing appliances before purchase, the stated annual consumption in kWh is the decisive figure.

How long does a fridge last?

Its lifespan depends on how it is used, where it is installed, how well it is maintained and the type of appliance. Regular cleaning, unobstructed ventilation and following the instruction manual can help keep it running properly. If you notice unusual noises, damaged cables or problems with the cooling circuit, do not open the appliance yourself. Contact the responsible customer service team instead.
