Comparison Tefal IXEO Power QT 2022 vs Rowenta QR 2020

System that prevents the formation of scale inside the steamer boiler.

Scale – insoluble limescale – produces several undesirable effects at once. Firstly, it reduces the efficiency of the heating element, and over time it can completely disable it. Secondly, particles of scale can peel off the surface of the boiler and contaminate the pipelines, hoses and nozzles of the device. Thirdly, when they get on the surface to be washed or on the clothes to be steamed, such particles can form new contaminants, that are sometimes very difficult to remove. Scale is formed especially quickly when using "hard" water, with a high content of calcium salts; however, even "soft" water is not insurance from this phenomenon.

To avoid all this, modern models provide limescale protection. This feature is usually performed by a special filter that removes calcium salts from the water used; in other words, scale still settles in the apparatus, however, not on critical structural elements, but on a part specially designed for this purpose. It should be borne in mind that filters have a limited resource and require periodic replacement (and the harder the water, the more often such a replacement will have to be done).

The length of the cable with which the device is connected to the mains. The longer the power cord — the farther from the socket the device can operate, the more freedom of movement the user has. On the other hand, an unnecessarily long cord can create difficulties both during operation and in storage/transportation; and when working away from the socket, you can use an extension cord.
