You’ve bought a new freezer, but you’re not quite sure what the ideal temperature should be? We’ll give you all the information you need and explain how to recognise when the temperature is too low or too high.

Your freezer temperature is too low

You may be wondering what the ideal temperature is for your freezer. Your freezer’s temperature is too low when it drops below the optimal storage temperature. The recommended ideal temperature is around -18°C. If your freezer temperature falls below this level, your food can freeze too hard. This affects the taste and texture of your food. It can also lead to excessive energy consumption. That’s why it’s important to check your freezer temperature regularly. Many freezers display this digitally. Is your freezer temperature too low? Adjust the settings or contact a professional engineer to identify and resolve the issue.

Your freezer temperature is too high

Your freezer temperature is too high if it rises above the recommended temperature. In general, -18°C is considered optimal. If your freezer temperature is too high, food products may start to defrost and spoil.

How can you tell if your freezer temperature is set too high? You can check the digital thermometer on your freezer. But if you notice food in the freezer starting to defrost, or if ice begins to melt, that’s a clear sign the temperature is too high. An unusual smell in the freezer, or excessive ice build-up, can also indicate temperature fluctuations.

Do you notice any of these signs, or do you know your freezer temperature is too high? Try to find the cause as quickly as possible and take prompt action to lower the temperature. Check the settings, the door seal, and carry out any necessary maintenance to ensure it works properly again.

How can you save energy costs with your freezer?

There are several ways to save on energy costs when using a freezer. Here are a few tips to help you save energy and use your freezer efficiently:

A white fridge stands next to a kitchen area with shelves, an orange accent wall, and a table with food.

Freezer placement: Place the freezer in a cool, well-ventilated location, away from heat sources such as direct sunlight, radiators and ovens.
Defrost regularly: Keep the freezer free of ice by defrosting it regularly. An ice-free freezer runs more efficiently and uses less energy.
Optimal filling: Keep the freezer well stocked but not overfilled. A well-filled freezer helps retain the cold, so it can run more efficiently.
Temperature setting: Set the freezer to the recommended temperature (usually -18°C). A lower temperature increases energy consumption.

Open white freezer with two clear drawers. The bottom drawer has food inside.

Good seal: Make sure the freezer door seal closes properly to prevent cold air from escaping.
Regular maintenance: Keep the condenser and ventilation vents clean and free of dust to ensure good airflow.
Energy-efficient models: When buying a new freezer, consider an energy-efficient model with a high efficiency rating (with A being the most energy-efficient).

By following these tips, you’ll use your freezer more efficiently and save on energy costs. Another option is to choose a smaller freezer, such as a tabletop model. Thanks to its compact size, it’s easier to keep it well filled, which is a good step towards achieving the ideal freezer temperature.
