Modern canons of interior and comfort dictate rather harsh conditions for the installation of all life support systems in homes and offices. A special problem in this case is the room heating system, because you can’t hide it inside the wall or behind partitions, you can’t just give up, take it to the utility rooms, the heat should flow constantly and as efficiently as possible. To solve these issues, there are vertical radiators.
What is the difference of vertical radiators?
Most of the model range of heating radiators can be described as vertical - this only indicates the location of the heating sections. However, models of small width and considerable height are distinguished into a separate class. A clear definition does not exist, so the vertical radiator can be distinguished from the others primarily visually.
Due to the physical characteristics of the distribution of warm air, some requirements apply to the placement of radiators. Traditionally, they are installed under the windows, below the window opening, to block the flow of cold air from the window and retain heat in the room. What to do if the windows are panoramic, or part of the wall from the floor to the window sill is too small to install the battery?
Main types of radiators
Based on the material of manufacture and design, vertical radiators are divided into several main types:
Cast Iron Radiators
Classically verified and traditional for a long time, the material is not always used for the production of unpresentable accordions. Modern options can have a stylish look, grooved or smooth surfaces, various colors, be decorated with casting and blackening, and correspond not only to rooms in the "retro" or "Soviet" style.
Today, they are produced by art casting technology, complemented by suitable taps, plugs, stands and holders. These are rather high radiators than vertical ones, because cast iron retains heat well and there is no need for a large surface area. Their disadvantages are the instability of cast iron to directional strong point impacts and heavy weight, so the sections are quite difficult to securely fasten to walls or partitions, they are provided with legs and stand on the floor in addition to wall fixings.
Steel radiators have high heat dissipation, they heat up very quickly, are lightweight and are easy to install, regardless of the size and number of sections. However, due to the design, they do not tolerate hydraulic shocks, and can become a source of leakage when connected to a central heating system. Rapid cooling makes them energy-consuming and unsuitable for autonomous heating systems. They are divided into three types: panel, tubular and sectional.
Vertical panel radiator
Vertical panel radiator - the most popular model. A neat appearance, a smooth surface, a multitude of shades and the ability to hold self-applied drawings make it possible to harmoniously fit them into any interior in the form of decorative panels.
Models with convectors create an excellent thermal curtain when placed under windows. Vertical radiators of this type are often placed under Alpine vents, skylights or with the expectation of heating stairs and interfloor passages in private homes. If the apartment has only one floor, then the convector is not needed, as the heat curtain will be created under the ceiling, and the cost of models without it is much less.
Tubular Vertical Batteries
Tubular vertical batteries look very original and allow you to create designs up to three meters in height, which is perfectly used for rooms with high ceilings. They can have any color, shape (up to twisted ornaments and crossed nodes) and bends, as they are made of separate sections-pipes and connected by welded headers, which allows to satisfy the most captious designers. Such designs rarely have sharp corners and are safer for children's rooms. The presence of welds also makes them vulnerable to hydraulic shocks, so the probability of leakage in centralized heating systems is high.
Sectional batteries made of steel do not have very high operating parameters, but they are captivating for their low price and detachable design. The ability to change the section, to increase or vice versa, to reduce the surface is sometimes crucial when buying. Sections are not issued above two meters and look very neat in appearance, and they are often given the appearance of artistically decorated panels. A very small weight allows connection and installation on walls and partitions of low-strength materials.
Vertical bimetallic radiators
Vertical bimetallic radiators are considered the most efficient and reliable. They are made of internal pipes of stainless alloy or copper, which are in direct contact with the coolant and the external heat exchange casing of aluminum with enamel coating. Outwardly, they are no different from aluminum radiators, but significantly outperform them in performance, which is especially valuable at the height of the heating season, and justifies their higher cost. Installed in an apartment with a central heating system, they can prevent leaks due to pressure drops in the pipes.
Structurally, there are also collapsible and non-collapsible versions, each of which is designed for a certain thermal power, and most models are equipped with thermostats. Many examples of vertical radiators, including designer models, can be seen on the KWTO website.
Advantages and disadvantages
The positive sides of the vertical radiator include both practical and aesthetic features of the structures:
- Rational use of space in the room. Greater heat output can be inserted into a rather narrow wall space by increasing the heat exchange area vertically.
- The spread of thermal radiation over the entire height of the battery. The location and height of the heating radiator itself can deliver quite a few pleasant minutes to a person, especially when entering a room from frost.
- The maximum range of models that will allow to realize any design decision.
- Additional features allow you to turn heating radiators into vertical mirrors, clothes dryers, decorative partitions and panels.
- Due to the smaller movement of warm air from the lower layers to the upper rooms, the movement of dust is also limited.
New models in the form of a frame for a mirror, a solid or lattice wall panel, a matte or painted wall are increasingly finding their fans among designers of the premises, and variations in size from very narrow to very wide allow you to not only intelligently adjust the temperature in the room, but also to give directionally heat.
Of course, such extraordinary solutions also have disadvantages:
- Heat transfer is built inefficiently. That is, at the top of the room is warmer than at the bottom, due to the accumulation of warm air under the ceiling. However, many people find some advantages in this in the form of warm staircases and interfloor passages that perfectly heat the installed radiators of the lower floor.
- High probability of air traffic jams.
- The complexity of the connection. It is necessary to carefully hide all supply pipes, fixtures to maintain an aesthetically pleasing look. Also vertical and horizontal deviations are unacceptable. It is necessary to use the bottom connection, which is rarely optimal for heat transfer.
- Requirements for high strength walls come from the massiveness of the structure. The size of the radiators is quite large, and although they seem rather light without filling, their weight with water is quite large. This imposes some restrictions on the location on the walls.
- The cost of vertical models often greatly exceeds the price of traditional options.
Today's wealth of forms, layouts and variations of interiors can be heated by far from every horizontal heating element, so the installation of vertical radiators in many cases serves as a salvation. Many models and structures provide an excellent opportunity to competently combine rationalism and creativity, because such unusual and attractive designs will regularly serve for many years.
