Refrigerators: 9 tips for saving energy and saving money
1. Get rid of your old refrigerator
Old refrigerators and freezers absolutely guzzle electricity, so you should give serious thought to buying a new appliance. Liebherr offers a wide range of highly energy-efficient appliances in the highest energy efficiency class currently available, A+++. With our CBPesf 4043 fridge-freezer we have become the only manufacturer currently offering an appliance with an energy efficiency level that is 20% below the A+++ efficiency class threshold.
2. Buy an energy-efficient appliance
The information on the energy label gives a clear indication of a refrigerator’s energy efficiency. The following rule of thumb applies: the more + signs after the A, the more energy efficient and economical the appliance.
3. Location is crucial
Never place your refrigerator next to a heat source such as an oven, hob or radiator, and avoid direct sunlight. Regardless of whether you have a freestanding appliance or a built-in one, always ensure that your refrigerator has sufficient ventilation so that the compressor does not end up running continuously. Note: we have covered the five main points you should consider when planning a kitchen in this article.
4. It’s all about the temperature
The optimum temperature for refrigerator operation is 5 °C, and -18 °C for freezer operation. As a rule of thumb, for each additional degree of refrigeration output about six percent more electricity is used. An accurate temperature setting can therefore directly save you money.
5. Beware! Always close the door without delay
Every time the refrigerator door is opened, cold air escapes and warm ambient air enters. To compensate for the temperature increase in its interior, the refrigerator must then use energy to bring the temperature back down. Always avoid opening the door unnecessarily and for too long.
6. Defrost food in the refrigerator
When defrosting frozen food place it in the refrigerator. Not only does this ensure that the food is carefully defrosted, its presence cools down the refrigerator interior, reducing the amount of work that the compressor has to do, and therefore lowering energy consumption.
7. Only place cold food in the refrigerator
Never put warm food in the refrigerator as this will heat up the interior, as well as other stored foods. Hot food should always be allowed to cool to room temperature before placing it in the refrigerator.
8. Defrost the freezer compartment
A thick layer of ice in the freezer compartment acts as a form of insulation and the appliance has to use more energy to cool the interior; therefore, we recommend that you regularly defrost your freezer. Liebherr has a great alternative in this regard – appliances with Liebherr’s NoFrost technology never need to be defrosted!
9. Check door seals regularly
The rubber seal is used for insulation purposes and prevents heat exchange between the ambient air and the refrigerator. It is important to regularly check that the seal is fully intact and sealing tightly. Should this not be the case, replace it immediately! Also, make sure that stored items doesn’t prevent the door from closing properly.
