It is known that it is impossible to achieve complete comfort in the room without high-quality heating. To obtain a good microclimate, it is necessary as a question of the status of the elements of the system.

Because with low temperature drops, the insulation of the walls and good windows still help to support the necessary level of comfort, but in severe frosts of the battery should be given maximum heat. Of course, an oil radiator can be used, but its ability to absorb electricity will issue an inspired account subsequently.

Criteria for selecting radiators

If we consider the selection of batteries for manufacturers, the market quite a lot of companies offering only high quality products. The cost of domestic radiators is not much different from the batteries, issued abroad. The price of the radiator is made depending on the characteristics and quality of the material. Guaranteed to provide long-term operation of the company products:

• KERMI (Germany);
• Zehnder (Germany);
• Radiatori 2000 S.p.A. (Italy);
• PURMO (Finland);
• Vogel & Noot (Austria);
• RIFAR (Russia);
• "KZTO" (Russia).

Existing types of radiators

Yield one - to provide a replacement of the old and existing inefficient heating elements. To this end, the construction market offers a variety of radiators:

• cast-iron;
• aluminum;
• steel;
• bimetallic.

Terrific cast iron radiators

In Soviet times, mainly installed iron batteries, they can now be found in many apartments. Due to the properties of the metal radiators data differ durability and efficiency. They have a great advantage - at the present as heating systems and water supply are resistant to corrosion. Thanks to the good performance of cast iron radiators continue to be installed in new buildings.
Among the disadvantages of the limitations of the design feature, but even a nuance correct because foreign manufacturers produce models of the original appearance, fit into any interior. If it is impossible to buy such products always come to the rescue decorative radiator grilles, which hide all the design flaws.

Aluminum radiators - available output

All aluminum radiators are separate heating sections collected in via nipples. After the appearance on the market of steel constructions in demand among a wide range of customers due to its compactness and functionality. But over time, the owners of systems with aluminum panels are faced with some problems. Significant disadvantages are the features:

• rapid wear of the gaskets in the system;
• the occurrence of permanent damage in the absence of air offtakes;
• intolerance effects of other metals;
• rapid cooling system.

The first point implies constant control over the quality of water in the system, which is almost impossible in modern conditions. At an elevated level of rigidity of water, the gasket simply come into disrepair. Also in the system there should be constantly water, when starting as a coolant antifreeze, rubber gaskets are instantly wear out.
The air vents should be designed in the system before the start of installation, they help to level the heating temperature of the radiator surface. It happens that when starting, air clusters arise, due to this battery, it can be heated unevenly, the circulation of the coolant is disturbed. The use of airlows allows you to function normally with the entire heating system.
Corrosion and destruction of individual system elements can begin when using pipes from another material due to metal activity. Therefore, any compounds must be performed only from aluminum components.
The last disadvantage has two sides, because the rapid cooling of the radiator is ensured due to high heat transfer. Accordingly, the material quickly heats the room and gives heat.

Steel batteries

The design of such radiators can be:

• panel;
• sectional.

Each consumer chooses the appropriate option depending on the application. Panel batteries are considered durable and reliable, they are resistant to various damage and have good characteristics. However, there are one nuance - if necessary, it is impossible to strengthen the heating of the room due to the standard sizes of the panels.
In this case, sectional batteries have an indisputable advantage - you can always increase or reduce the amount of heat released by adding items. Steel radiators resistant to pressure surges in the system due to welding connections. However, with external influences or hydraulic blows, such batteries fail due to the subtleties of the metal.

Bimetallic designs

The universal option for heating systems are bimetallic radiators, they combine the dignity of steel and aluminum. The design is a sectional, so if necessary, you can always change the number of heating elements. The battery case is made of steel, and from above the coating is performed from aluminum. This gives the improved characteristics of the coolant, durability and strength to various damage. A long service life is provided by resistance to the emergence of corrosion. Specialists recommend in many cases to use bimetallic structures, but not all consumers agree due to the financial point of the issue.

Calculation of the required number of sections

Before installing radiators, it is worth correctly designing the system, calculate all the necessary components. It is customary to install batteries directly under the window, then the thermal energy will block the flow of cold air outside. The number of sections required for heating is calculated by a special formula:
n \u003d s x100 / Δt, where s-location location;
Δt- Indicator of the heat transfer element.
This formula is suitable for housing with the height of the ceilings not more than 3m, with other indicators use 40xH instead of 100. The heat transfer indicator can be found in the passport to selected sections from the manufacturer.
The regulation of values \u200b\u200bin some cases is also supplied:

• for angular rooms with non-warmed walls, add an additional pair of sections;
• in areas with low temperature indicators, the calculation is carried out individually, the value obtained is increased by a third;
• when the heating radiators are located in places with limited air circulation, the number of sections should increase by 10-15%.

Installing a new radiator in the system

Before starting the installation or replacement of radiators, it is worth considering the project and coordinate it officially. For compiling you will need the relevant specialists who competently hold all measurements and calculations. Installing batteries requires such a set of items:

• radiators;
• fastenings;
• cranes of the ball and Maevsky;
• a set of keys;
• sealer;
• silicone sealant.

First, the radiator is collected, all threaded connections, plugs and cranes are installed. The joints compact pacles and sealant to prevent the appearance of flops. Next, water is descended from the system, old batteries from the riser are turned off. A place for new radiators is prepared, fasteners are installed. They hang out a new radiator and joins the pipes with ball valves.
It is important to install the battery correctly by level. It is worth considering the distance to the floor, walls and windowsill, which should be at least 50mm. At the end, it is better to check the tightness of the connections, after starting the system, they can be tightened. Maevsky's cranes will also come to the rescue, they will help achieve even heating of the entire radiator due to the removal of air traffic jams.
