Truth or lie: putting magnets in the fridge uses more energy

A family belief is that placing magnets at the door of the fridge oh fridge will make you consume more energy, which is an economic problem and wear and tear on the device. But this consequence does not really exist.

The myth has been around for generations and although they are magnetic objects that stick to the metal door, the energy and heat they generate is not great enough to impact the door. energy consumption.

“If we talk about conventional ferrite fridge magnets, they create a rather weak magnetic field. However, you can now buy other types of magnets, neodymium, iron and boron, which are strong enough to affect electronic equipment. In these cases, it is better to use ferrite magnets,” physics professor Yuri Mikhailovsky told the Sputnik news agency.

There is also no consequence in its operation that negatively or positively affects any operation of the refrigerator. This makes it safe to put these decorative elements on unless someone obstructs the closing of the door, which is a problem because the refrigerator will receive hot air and will have to work harder.

The opposite happens with computers, according to Mikhailovsky. Estos devices si pueden sufrir al tener imanes cerca, porque el disco duro que usa tiene “los principios de la grabación magnética” y un “magneto potente con su campo puede demagnetizar el disco, así que hay que tener cuidado y no colgar imanes al lado from him”.

Decorating a refrigerator with magnets is not a concern, just like other customs that people tend to have with this appliance that impact daily energy consumption.

One of the most common is constantly opening and closing the door. It is normal that it opens to look for a product and that we forget another that we need. But this error must be minimized because the refrigerator will perform the same activation process each time the door is moved and this represents more consumption.

It is also usually an error the location of the fridge. You should always opt for a cool space that is not exposed to direct sunlight, an oven or stove, as this will mean more work to keep it cool.

To these practices must be added constant internal and external maintenance, checking its correct operation without generating temperature peaks or untimely shutdowns. In addition to cleaning the ventilation sections and the freezer, if it is a frost refrigerator that produces a lot of ice.

An average two-person household consumes about 3,050 kilowatt hours per year, explains the energy advisory service of German consumer centers.

According to a survey conducted by the Federal Association of Energy and Water Industries (BDEW) for the year 2021, consumer electronics such as televisions and game consoles account for 28%, slightly more a quarter of total electricity consumption.

By way of comparison: according to this study, washing and drying clothes consume 14% of electricity, lighting 13% and refrigerators and freezers 11%. They are followed by the kitchen and the dishwasher, with 9 and 8% respectively. These values ​​add up to 55%.
