To date, there are manyvarieties of heating radiators, among which metal structures occupy a leading position. From a technical point of view radiators are called hollow inside heating appliances, consisting of several sections. The design is filled with hot water and due to the thermal conductivity of the material, cold air in the room heats up. In order for the metal radiators to fully perform their functions, it is necessary to choose the correct design.
The main parameter for selecting a metal radiator is the compatibility with the heating system of the house. There are two types of systems:
Compatibility with the type of heating system is determined by compliance with such parameters as:
These indicators are indicated in the technicalcharacteristics to any metal radiators. The central heating system requires a more careful selection of the radiator, since it must calmly tolerate pressure and temperature changes, low water quality. The non-compliance of the technical characteristics with the requirements may cause a failure in the heating system or the failure of the radiator itself.
By type of material radiators are divided into the following varieties:
The cost of heating equipment is divided into the following classes:
By type of construction, the following types are distinguished:
The characteristics of metal radiators are the main criteria for choosing a design for use.
Aluminum radiators can be divided into two types:
Heating radiators made of aluminum are popular for use in multi-family houses with an open type of heating system.
Steel radiators can also be divided into several varieties, which have their own characteristics:
Steel metal heating radiators are often used in private homes with an individual heating system.
Appearance of classic cast iron radiatorsheating is familiar to everyone, because they were installed in all houses built in the USSR. They are distinguished by their durability and capable of serving for several decades.
Cast iron for the production of heating devicesresistant to corrosion and poor water quality. Calmly tolerates temperature and pressure changes. The heat transfer rate reaches 70%, the remaining 30% go to convection and contribute to the heating of the lower zones of the heated room.
The disadvantages are a lot of weight thatsignificantly complicates the installation, as well as a rough inner surface, which contributes to a gradual clogging of the structure and poor conductivity of the water. However, this defect is eliminated by periodic flushing of the system with high pressure water. The cost of such radiators is relatively small, and the service life reaches 50 years.
This type of heating structure is consideredthe most optimal, although the most expensive. It combines the best properties of aluminum and tubular products. They are characterized by high thermal conductivity and an optimum service life of 25 years. A light weight contributes to ease of installation work.
The design combines an aluminum frame andInternal steel elements that are resistant to corrosion. Also, due to some features, bimetallic radiators are resistant to pressure, temperature and presence of impurities and additives.
Heat transfer characteristics affect the level andthe speed of heating the air in the room, so it is it is considered the main criterion for choosing a radiator for the house. This parameter depends on the material from which the radiator is made. The best characteristics are observed in copper and cast iron structures.
The choice of a heating product depends not only on the heat transfer, but also on the set of other parameters, such as:
For high-quality heating of the room plays a rolenot only the heat transfer of the heating structure, but also the correspondence of its size to the area of the room. For large rooms, a large surface of the heating element is required.
The optimum width of the radiator should be at least 60% of the window size. In this case, it should be located under the windowsill at a distance of 6 cm from the floor and 10 from the window.
Screen for metal radiatorsUsed to decorate the latter under the general interior of the room. With its help you can not only add coziness to the house, but also hide the external defects of old cast-iron structures. In addition, it is often used to protect children from accidental contact with a heated structure.
Screens are produced from such materials as:
Often screens do not have functional characteristics and are installed only as a decorative element.
Reviews about metal radiatorsnote the good quality characteristics of products, thanks to which there is a rapid heating of the room and maintaining the desired temperature. Their choice depends on the financial possibilities, personal wishes and requirements for the design.
