The technological progress of household appliances has been so spectacular in recent years that even the information labels they include have had to be modified as we explained a few days ago in Efimarket in our article on the new energy labelling.
In our blog you will find more articles like this one that will help you achieve greater energy efficiency and reduce your electricity bill.
The new energy labels cover three basic types of household appliances: refrigerators, washing machines
In refrigerators, an A+ appliance consumes up to 20% less than A; an A++ up to 40% less and an A+++ up to 60% less than A. In washing machines, the A+ is up to 13% more efficient than A, 24% in the case of A++ and 32% in the case of A+++. In dishwashers, the values are similar to washing machines: 11%, 21%
A 300 litre Class A refrigerator consumes about 355 kWh per year, which is reduced to about 220 kWh if it is A++ and over 600 kWh if it is old, Class D. The savings of a refrigerator A + + compared to an A exceeds 15 euros per year and 20 euros of one A against another C. The purchase of a more efficient appliance is profitable in a few years on the electricity bill, plus savings of water and soap.
Improvements for the sake of efficiency
Apart from European regulations, manufacturers of household appliances have for many years been innovating their products to make them more ecological, efficient and comfortable, in the sense that they consume less electricity and water, make less noise and vibrations and perform their primary function better, be it cooling a food, cooking it or washing and drying clothes or dishes.
Although a priori some improvements may seem imperceptible, the incorporation of a mechanical element or an electronic control may, however, cause its effectiveness to skyrocket. Electrolux has placed a spray arm in its RealLife dishwasher that sprays sprayed water from all sides and cleans the dishwasher better, even if it is placed in a more disorderly manner.
Bosch and Siemens have placed zeolite balls at the base of their dishwashers, which absorb moisture as it dries, leaving no traces of water jets. Zeolite is a moisture-absorbing material. It does not need to be replaced.
LG uses water vapour in its washing machines, which dissolves dirt better with less water and soap. Samsung has opted for bubbles in the Eco Bubble range, based on injecting air into the mixture of water and detergent before the washing cycle, which ensures that this system saves a lot of water, soap and electricity and clothes are cleaner.
Miele has added the steam function in some washing machines at the time of centrifugation, so that the clothes are less wrinkled. The side panels of some Bosch and Siemens washing machines are wave-shaped and so noise is absorbed.
Sometimes the changes are mechanical. LG rotates the drum with a directly coupled rotary motor, without the classic drive belt. The result is less noise and more usable space. Panasonic has slightly tilted the drum, which washes clothes with less effort.
Today’s refrigerators and freezers are much more efficient thanks to the rotary compressor that never stops and regulates its cooling power. Classic refrigerators are stopped and started with the characteristic noise and every time they are started up, they consume a lot of energy.
Fagor has put the icing on the cake with refrigerators that include vacuum-packed food. There has also been
In addition, it has memory and if you move the container is lit with the same power in the new location. It can be cooked with a single plate covering the entire surface or with 20 small saucepans. Bosch has developed a similar system. In electric ovens, the novelty lies in the incorporation of water
