Modern heating radiators meet all the requirements of the consumer: they, due to the design and materials used, have good heat dissipation and appearance. No designer will call this heater an attractive piece of furniture. This problem can be solved by applying screens to the heating battery. The types, design features of these elements will be discussed in this publication.
Types of screens and their purpose
All screens for radiators can be divided into three large groups:
The function of the former is to protect a person (pets) from injuries associated with burns on the heated surface of the battery. In addition, the use of protective screens significantly reduces the risk of injury from the protruding parts of the batteries, which is especially important in families with small children.
From the author: Initially, radiator shields were used solely to prevent damage to fragile cast iron batteries.
Decorative elements are designed to give an attractive appearance to old batteries, which cannot be replaced at the moment for any reason. Today, the widest choice of decorative screens for heating radiators is presented on the domestic market. Due to this, the consumer can easily pick up this element and harmoniously fit it into almost any interior.
The third type of screens is used to reflect IR radiation from the wall into the room. As a rule, these elements are made of polished metal and are installed behind the battery.
A few words about the principles of heat distribution
As you know, a heating radiator is used to heat a room. The principle of operation of any battery is to create convection air currents. In other words: cold air enters the radiator from below. Rising along the surface of the heating device, the air masses heat up and rise to the upper part of the room.
Based on this principle of operation, any grating or screen (except for elements of a reflective type) will interfere with the convective circulation of air masses, and as a result, reduce the efficiency of heating devices.
Important! To save the maximum amount of thermal energy transferred from the radiator to the room, it is necessary to use screens without a top cover and free air access to the bottom of the battery. Most of the screens for heating radiators, the photos of which are presented below, significantly reduce the operation of the heating system.
Screen material and shape selection
So, how to close the radiators? All screens for radiators differ in shape, appearance and material from which they are made.
According to the shape and method of fastening, these elements are of four types:
- Mounted, without top cover. This design is used for radiators located in a niche. They do not require special installation and do not interfere with the heat exchange process.
- Mounted, with lid. Most often, such elements are used as a screen for cast-iron heating radiators that protrude from under the windowsill.
- Flat, wall-mounted, cover only the front side of the battery, leaving the top, bottom and sides open.
- Screens in the form of a box are used in cases where it is necessary to completely hide the battery. These structures are floor-mounted or wall-mounted.
As for the material, screens, regardless of purpose, can be made from:
- Wood or wood products.
Metal screens for heating radiators are in the greatest demand due to their low cost, durability and almost no effect on the efficiency of heating devices.
Advice! The service life of metal elements depends entirely on the quality of their color. Choose designs that are powder coated.
There are also more expensive (exclusive) metal products made using artistic forging.
Tip: If a forged product is supposed to use a background, then the best option would be to make it from perforated material.
Plastic screens for heating radiators are environmentally friendly, hygienic and perfectly tolerate the processes of repeated washing with the use of detergents.
That is why they are most often used in bathrooms and rooms with a high level of humidity. These elements are made of plastic, resistant to temperature effects.
Tip: if your choice fell on a plastic screen, then experts recommend paying attention to the design of the lamellas (transverse bars of the lattice). The efficiency of the heating devices will not be impaired if the lamellas are located at an angle with respect to the vertical plane.
Wooden decorative screens for heating radiators are considered elements of the premium segment.
Such products look expensive, which allows them to be used even in the most sophisticated interiors. It should be understood that the external beauty hides the low heat transfer efficiency of batteries closed on all sides. There are also simpler, and most importantly, effective options for decorative elements for heating equipment. As a rule, they are a wooden frame with a lattice on the front side, made of rattan, bamboo, etc.
Today, on the domestic market, decorative panels for heating radiators made of their MDF are quite well represented. These are products made from pressed wood fiber, in which lignin acts as a binder, which is released by the wood itself during the manufacturing process. This material is environmentally friendly and with a minimum thickness (3–4 mm) perfectly keeps its shape, despite the abundance of perforation.
Glass products are not ideal from the point of view of heat engineering and are subject to destruction under mechanical stress. However, due to their attractive appearance, these elements are quite in demand among the European consumer.
