Zehnder (radiators): overview, description, types, characteristics and reviews

Heating equipment in modern designs allows to provide heat to a large building and production premises with high demands for operating microclimate parameters. But in the case of private houses and apartments, high power potential is not always the main criterion of choice. For example, in providing a small small family, considerations of compactness come to the forefront, and when providing communication units for a cottage or penthouse, a prerequisite will be aesthetics and compliance with design requirements. Such requirements are met by Zehnder heating radiators, which are also famous for the stable performance of direct heating tasks. The German manufacturer produces units in different configurations, which enables customers to purchase the most suitable models for specific application conditions.

General information about Zehnder radiators

The company is focused on a segment of equipment that integrates into the system of water heating. In essence, this is the concept of traditional radiators, but in a modern interpretation. The basis of the aggregates is a metal structure, formed by several sections. Developers are especially careful when it comes to technological protection of equipment surfaces. For all the strength of steel tubular radiators Zehnder in conditions of intensive operation can be subjected to destruction processes. To prevent such phenomena, the manufacturer exposes the units to several external processing sessions. At the first stages, the surfaces are cleaned, followed by a primer with electrostatic painting using powder enamel. At the final stage, antistatic and thermal final treatment is performed.

Unit Characteristics

The most popular is the Charleston line, so the rest of the range is oriented to its technical parameters. The standard width of the elements is 4.6 cm, with the height of the sections reaching 180 cm. Each radiator panel also has a metal head 1.5 mm thick. The number of sections can be different depending on the modification - the standard range varies from 4 to 12 elements. Of course, from the user's point of view, the most important performance indicators are provided by Zehnder steel radiators under optimal operating conditions. With regard to power, it is 188 watts for the basic configuration. This is not enough, and modern boiler plants, of course, demonstrate a more impressive return, but for the average needs of a city apartment this will be enough. The temperature regimes are different, but the maximum is 120 ° C. The pressure in the circuits is 10 bar.

Types of structures

The models are offered in several forms, the main of which is the traditional panel construction. Outwardly such versions resemble a lattice of pipes, which, however, has a very attractive appearance. It is at the expense of an aesthetic look that German radiators can not be masked and operated in an open form - they will not spoil the style of the interior and even bring their own designer 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 form. These are radial and angular 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. Angle models are usually used for installation in bay windows. Designers form angles in the range of 90-179 degrees.

Technological features

Against the backdrop of the emergence of ever more productive boiler and furnace units with small dimensions, the class of radiators as a whole is gradually dying out, unable to withstand competition. However, German experts are trying to maintain interest in this niche through the development of models in different directions. In particular, the design of modern units implies the possibility of replacing individual elements of Zehnder. Radiators with minimal effort are renewable, which extends their service life. This protective coating of special enamel also gives many advantages - for example, all surfaces are available for washing. Regardless of the temperature regime, the coating from a special solvent does not emit harmful substances, so radiators can also be used in residential areas.

Ways to connect radiators

This is another feature of the German equipment. A variety of connection options extends the range of application of the radiator and makes installation convenient. As practice shows, the most popular is the lateral type of connection, which allows both a bunch with the central riser, and with room wiring of pipes. If possible, many use a less noticeable lower eyeliner, but in this case, you can not do without the use of a special thermal valve Zehnder. Radiators can be connected from above. This option is considered less convenient and less attractive, but in some cases this is the most rational solution. Regardless of the method of connection, the manufacturer suggests using and addition in the form of special thermostats. These are devices that allow you not just to adjust, but to control the parameters of the operating modes of the equipment automatically.

Positive feedback about radiators

Radiators, as such, are valued by the consumer for their small size and pleasant appearance. It is on these characteristics and the manufacturer Zehnder makes a bet. Radiators are offered in different stylistic designs, which, in fact, attracts a large part of the target audience. The owners also respond positively to a simple and effective management system. All electronics and mechanical controls function accurately and reliably. Here it is worth emphasizing and reliability with security. German equipment rarely raises doubts about quality and the Zehnder brand confirms this by the example of its own products.

Negative feedback

Like the positive qualities of this equipment, the negative aspects of its operation come from the very concept of the device. Radiator as heating equipment was originally considered an auxiliary component, so it is not able to provide the proper 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, we can note a high cost, which on average varies from 16 to 20 thousand rubles.

How to choose the best model?

First, you need to determine the heating needs and compare them with the capabilities of the radiators. If, in theory, the equipment is capable of ensuring the performance of the intended functions, then it is possible to proceed with the selection. Actually, it is necessary to focus on two main criteria - heat output and design performance. To some extent, these are interrelated characteristics, since the effectiveness of the dimensions that the plants have is dependent on them. For example, 14-section tubular radiators Zehnder are capable of operating at a maximum temperature of 120 ° C. In order to ensure the maximum heat transfer, it is also necessary to consider the options in terms of shape. In some cases, the traditional wall layout will be advantageous, and in small rooms and the angular version of the design will successfully cope with the tasks assigned.

Conclusion

Steel sectional designs of heating elements are still the best solution for use in residential areas. As one of the best examples of such equipment it is possible to consider the radiator Zehnder Charleston Completto, which combines both design appeal and high heat output. In comparison with alternative heating systems, such units practically do not bring hassle in the content. They do not require the performance of maintenance work and present a minimum of requests for sanitary and hygienic care. Again, the treatment with a special anti-static coating has saved housewives from unnecessary trouble in the form of dust cleaning, and the ability to easily replace individual sections eliminates the need to contact service centers for repairs.
