Heating equipment in modern designs allows you to provide heat for large-area buildings and industrial premises with high demands on the performance of the microclimate. But in the case of private houses and apartments, high power potential is not always the main selection criterion. For example, in providing a small small family, considerations of compactness come first, and when supplying a cottage or penthouse with communication units, aesthetics and compliance with design requests will be a prerequisite. Such requirements are met by Zehnder heating radiators, which are also famous for their stable performance of immediate heating tasks. The German manufacturer produces units in different configurations, which allows customers to purchase the most suitable models for specific applications.
General information about Zehnder radiators
The company focuses on the segment of equipment that is integrated into the water heating system. In essence, this is the concept of traditional radiators, but with a modern interpretation. The basis of the units is a metal structure formed by several sections.Developers are especially careful when it comes to technological protection of equipment surfaces. For all their strength, Zehnder steel tubular radiators can be subjected to destruction processes under intensive use. To prevent such phenomena, the manufacturer subjects the aggregates to several sessions of external processing. At the first stages, the surfaces are cleaned, and then the primer is followed by painting in an electrostatic field using powder enamel. The final step is anti-static and thermal finishing.
Characteristics of units
The Charleston line is considered the most popular, so the rest of the model range is guided by its technical parameters. The standard width of the elements is 4.6 cm, while the height of the sections reaches 180 cm. Each radiator panel also has a 1.5 mm thick metal head. The number of sections may vary depending on the modification - the standard range varies from 4 to 12 elements. Of course, from the user's point of view, the performance that Zehnder steel radiators provide under optimal working conditions is most important. As for power, it is 188 W for the basic configuration. This is not much, and modern boiler plants, of course, demonstrate a more impressive return, but this will be enough for the average needs of a city apartment. Temperature conditions are different, but the maximum is 120 ° C. The pressure in the circuits is 10 bar.
Models are offered in several shapes, the main one being the traditional panel design. Outwardly, such versions resemble a lattice of pipes, which, however, has a very attractive appearance. It is precisely due to the aesthetic appearance that German radiators can not be masked and used in the open - they will not spoil the style of the interior and even bring their own design shades. Especially for those users who want to focus on the design effect through an unusual design, the developers also offer modifications with an unusual shape. These are the radius and corner models of Zehnder. Radiators of the first type are characterized by a curved design with a rounded contour. Curvature parameters may vary, but the first three sections always remain linear. Corner models are usually used for installation in bay windows. Constructors form angles in the range of 90-179 degrees.
Against the background of the emergence of more and more productive boiler and furnace units with small sizes, the class of radiators as such is gradually dying off, unable to withstand competition. However, German experts strive to maintain interest in this niche by developing models in different directions. In particular, the design of modern units suggests the possibility of replacing individual Zehnder elements. Radiators with minimal effort can be upgraded, which extends their service life. The aforementioned protective coating of special enamel is alsooffers many advantages - for example, all surfaces are accessible for washing. Regardless of the temperature regime, the special solvent coating does not emit harmful substances, so the radiators can also be used in residential areas.
Methods for connecting radiators
This is another feature of German equipment. A variety of connection options expands the range of applications of the radiator and makes installation convenient. As the practice of use shows, the most popular is the lateral type of connection, which allows both connection with the central riser and with apartment piping. If possible, many use a less noticeable lower eyeliner, but in this case, you can not do without the use of a special Zehnder thermal valve. Radiators can also be connected from above. This option is considered less convenient and unattractive, but in some cases this configuration will be the most rational solution. Regardless of the connection method, the manufacturer suggests using an addition in the form of special thermostats. These are devices that allow not only to regulate, but to control the parameters of the operating modes of the equipment automatically.
Positive feedback about radiators
Radiators as such are appreciated by the consumer for their small size and pleasant appearance. It is on these characteristics that the manufacturer Zehnder relies. Radiators are offered in different stylistic designs, which, in fact, attracts considerablepart of the target audience. Also, the owners speak positively about the simple and efficient control system. All electronics and mechanical controls operate accurately and flawlessly. Here it is worth emphasizing reliability with safety. German equipment rarely raises doubts about the quality and the Zehnder brand confirms this with the example of its own products.
As well as the positive qualities of this equipment, the negative aspects of its operation come from the very concept of the device. The radiator as heating equipment was originally considered an auxiliary component, so it is not able to provide the necessary power for the full heating of large areas. Nevertheless, Zehnder Charleston radiators are quite suitable for use in apartments and small houses. As for other negative aspects, one can also note the high cost, which on average varies from 16 to 20 thousand rubles.
How to choose the optimal model?
First you need to determine the heating needs and compare them with the capabilities of the radiators. If, theoretically, the equipment is capable of providing the intended functions, then you can proceed to the selection. Actually, one should be guided by two main criteria - heat transfer and structural design. To some extent, these are interrelated characteristics, since their efficiency depends on the size of the installations. For example, Zehnder 14-section tubular radiators are capable of operating withmaximum temperature of 120 °C. In order to ensure maximum heat transfer, options should also be considered in terms of shape. In some cases, the traditional wall-mounted arrangement will be advantageous, and in small rooms, the corner version of the design will successfully cope with the assigned tasks.
Steel sectional structures of heating elements are still the best solution for use in residential premises. One of the best examples of such equipment is the Zehnder Charleston Completto radiator, which combines both design appeal and high thermal efficiency. Compared to alternative heating systems, such units are practically maintenance-free. They do not require maintenance work and require a minimum of requests in terms of sanitary and hygienic care. Again, the special anti-static coating saves housewives the hassle of dusting, and the ability to easily replace individual sections eliminates the need to go to service centers for repairs.
