Buying a Fridge with Freezer Compartment: A Guide to Size, Energy Use and Features

A fridge with freezer compartment is one of those appliances where the wrong choice quickly becomes noticeable in everyday use. If the freezer compartment is too small, there is not enough room for stored food. If the fridge freezer is too large, it may not fit through doorways or could stand too close to the wall. Even a low purchase price can be offset by high energy consumption or an impractical interior layout.

The Joybuy Product Recommendation Officer therefore filters the most important details from product descriptions and categorises them according to typical usage scenarios. This makes it easier to decide whether a freestanding fridge, a compact mini fridge, a separate freezer or a large fridge freezer is right for your household.

Three common buying pitfalls when choosing refrigeration and freezing appliances

1. Capacity is not compared with the actual space required

The total capacity in litres initially sounds clear-cut. However, what matters is how it is divided between fridge capacity and freezer capacity. For example, an appliance with 175 litres of usable capacity may offer 122 litres for food in the fridge section and 53 litres for frozen food. Anyone who regularly freezes supplies will need a different layout from a household that mainly stores fresh food.

With a mini fridge, it is also important to remember that a stated total capacity of 45 litres does not automatically mean 45 litres of freely usable fridge space. A separate freezer compartment, door shelves and storage shelves reduce the space that is practically available.

2. “No Frost” is confused with being completely maintenance-free

A No Frost freezer reduces ice formation through automatic circulating-air cooling. In appliances with Total No Frost, this generally applies to both the fridge and freezer sections. Even so, cleaning the door seals, checking ventilation clearances and loading the appliance appropriately are still necessary.

Traditional appliances with manual defrosting can regularly develop a layer of ice. This takes time to remove and can reduce the usable interior space. If you want to keep maintenance to a minimum, check specifically whether only the fridge section defrosts automatically or whether the freezer compartment does too.

3. Energy class and annual consumption are not considered together

The energy efficiency class provides standardised guidance, but it does not replace checking the annual consumption in kWh. Two appliances in the same class may use different amounts of electricity depending on their size. For ongoing costs, the actual consumption shown on the EU product information sheet is therefore relevant.

An energy-efficient fridge should also be positioned with sufficient clearance from radiators and direct sunlight. Good ventilation supports the appliance’s intended operation and prevents the compressor from running unnecessarily long.

Technical details to check before buying

Dimensions, door hinge and installation location

Before ordering, checking the height, width and depth is essential. You should also take door-opening angles, skirting boards, worktops and the delivery route into account. A fridge with a reversible door hinge is useful if the opening direction needs to be adapted to your kitchen layout.

With freestanding appliances, the required air circulation must not be blocked by furniture or walls. The specific clearances are stated in the relevant instruction manual.

Noise level in decibels

The figure in dB(A) is particularly relevant for open-plan kitchens, studio flats, offices or guest rooms. Levels of around 38 to 40 dB are considered relatively quiet in a typical household environment, although the perceived noise also depends on the floor, distance from the wall and operating condition. An appliance rated at 35 dB, such as the Bauknecht KGDNF 20CD IN according to the product information, may therefore be worth considering for noise-sensitive rooms.

Freezing capacity and temperature

A 4-star freezer compartment is designed for the long-term storage of frozen food. The freezing capacity in kilograms per 24 hours indicates how much freshly added food the appliance can freeze within this period. Functions such as “Fast Freeze” are particularly useful after larger shopping trips or with a separate freezer containing large quantities of stored food.

Installation, care and ongoing costs

  • After transporting the appliance, leave it standing upright in accordance with the instruction manual before connecting it.
  • Use an earthed socket and avoid multi-socket adaptors or unsuitable extension leads.
  • Keep ventilation openings clear and avoid heat sources such as cookers or radiators.
  • Clean the door seals, shelves and interior regularly with a mild cleaning product.
  • With appliances featuring a manual freezer compartment, monitor the layer of ice and defrost the appliance when it starts to build up noticeably.
  • To calculate running costs, multiply the stated annual consumption by your electricity tariff. The actual figure may vary depending on the ambient temperature, how full the appliance is and how it is used.

FAQs about fridges with freezer compartments

How many litres should a fridge with freezer compartment have?

For one person, a compact appliance of around 80 to 150 litres may be sufficient if only small quantities are being stored. Couples often need more fridge space. Families generally benefit from a fridge freezer with at least around 250 litres, although individual storage needs are the deciding factor. For frozen food supplies, a separate appliance such as a 177-litre freezer may be the more practical choice.

How long does a fridge usually last?

The lifespan depends on the compressor, seals, installation location, care and intensity of use. Regular cleaning, sufficient ventilation and closing the door without unnecessary delay all help ensure trouble-free operation. If you notice unusual noises, continuous operation or declining cooling performance, consult the instruction manual or an authorised service centre.

How much does it cost to run an energy-efficient fridge?

Annual costs can be estimated as follows: annual consumption in kWh × electricity price per kWh. A small fridge using 85 kWh per year would cost approximately 29.75 Euro per year at an assumed tariff of 0.35 Euro per kWh. Actual costs depend on the tariff and operating conditions.
