Buying a freezer: what to consider when choosing, installing and using one

A freezer provides extra space for provisions, frozen meals and food you have frozen yourself. For households with high storage needs, a freestanding freezer is often easier to organise than a small freezer compartment in the fridge. However, some purchasing decisions can lead to unnecessary hassle or higher running costs later on.

You should check three common pitfalls before buying:

• Focusing only on capacity: A large freezer may not fit through doors, into alcoves or in the intended position.
• Assessing energy efficiency in isolation: The energy efficiency class alone is not enough for comparison. The annual consumption in kilowatt-hours is also important.
• Assuming garages and cellars are automatically suitable: Not every appliance works in unheated rooms. The permitted ambient temperature range must be stated in the technical specifications.

The most important freezer buying criteria

1. Net capacity and interior layout

The stated net capacity shows how much storage space is actually available. A 244-litre freezer, for example, is suitable for households wanting to store larger quantities of meat, vegetables, bread or prepared meals. For a realistic assessment, you should also consider the interior layout.

A freezer with drawers makes it easier to sort food by category. Transparent drawers and flaps reduce the time spent searching and help you use older provisions first. You should also check:

• Number and height of the drawers
• Load capacity and whether they can be removed
• Width of the compartments for large packages
• Whether there are flaps or open shelves
• Net capacity rather than gross capacity

A smaller appliance with a well-designed layout can be more practical in everyday use than a nominally larger interior that is difficult to access.

2. Energy consumption and operating noise

The energy efficiency classes on the current EU scale range from A to G. An energy-efficient freezer should have not only a suitable class but also a clearly stated annual consumption. To estimate running costs, multiply the stated consumption by your electricity tariff:

Annual consumption in kWh × electricity price per kWh = estimated annual electricity costs

The actual figure depends on factors including room temperature, how full the appliance is, how often the door is opened and maintenance. Good ventilation and a tight door seal help ensure consistent operation.

Appliances operating at around 36 to 40 dB(A) are considered comparatively quiet. A quiet freezer is particularly useful in open-plan kitchens, living areas or utility rooms. However, the dB rating describes the tested noise level; it does not mean the appliance will be completely silent.

3. Safety and maintenance features

A fast-freeze function temporarily lowers the temperature after larger quantities of food have been added. This helps prevent the frozen food already inside from warming too much. Follow the instruction manual and deactivate the function if it does not switch off automatically.

A temperature alarm alerts you if the internal temperature rises unexpectedly. This can be helpful if the door has not been closed fully or there has been a power cut. However, the alarm does not replace regular checks or correct loading.

Systems such as Low Frost or MinFrost can reduce ice build-up. With a conventional static appliance, regular defrosting is still necessary. No Frost appliances defrost automatically, but depending on the model, they may have a higher purchase price or different consumption figures.

Which design is right for your household?

A tall freestanding freezer makes efficient use of floor space and usually provides several easily accessible levels. It is suitable for kitchens, cellars and utility rooms. A chest freezer can offer plenty of space for large quantities of food that are rarely moved, but it is less convenient to organise.

For installation in a garage or cellar, the climate range is crucial. An appliance that, according to the product information, can operate at an ambient temperature of –15 °C is more flexible for unheated rooms than a model with a higher minimum temperature. The maximum ambient temperature must also be taken into account.

Before ordering, measure:

1. Floor space, including clearance from the wall
2. The appliance’s height, width and depth
3. Door and stair widths along the delivery route
4. The opening radius of the door or lid
5. Clearance for ventilation and cleaning

A reversible door makes it easier to adapt the appliance to existing furniture and walkways. The process varies depending on the model and should be carried out according to the instructions.

Plan installation and maintenance properly

Place the freezer on a level, stable surface. Leave the clearances required in the instruction manual for air circulation. Hot appliances, direct sunlight and blocked ventilation openings increase the strain on the cooling system.

Before switching the appliance on for the first time, leave it standing upright as specified by the manufacturer. Once it has been filled, do not leave the door open for extended periods. Food should be cooled and packed in portions wherever possible. Clearly labelling the contents and freezing date helps you plan your provisions.

Freezer FAQ

How much space should there be between a freezer and the wall?

This depends on the model. The manufacturer’s specifications are decisive. Additional clearance is often needed at the back and sides so that heat can escape. This space must be taken into account when planning where to position the appliance.

Is a freezer suitable for a garage?

Not automatically. Check the stated ambient temperature range and climate class. According to the product information, the Beko FS127940N can be used in unheated rooms down to –15 °C. Other appliances require considerably higher minimum temperatures and are not designed for a cold garage.

How much does it cost to run a freezer?

The cost is determined by the annual consumption in kWh and your electricity price. An appliance with annual consumption of 200 kWh would cost around 70 Euro per year at 0.35 Euro per kWh. Actual consumption may vary depending on the location, usage and room temperature.
