Steel radiator: characteristics, advantages, types

At arrangement of the house all the people think about it heating. Some are inclined to self-heating system, with radiator in each room.

From the choice depends on the quality of housing warm in the cold season over the next decades.

Features and advantages

• The temperature of the coolant, which withstands the battery reaches 120 degrees.
• Heat dissipation is improved, it varies from 1,200 to 1,800 watts, and some models it is the higher. Such an indicator is present in the convection heaters working method.
• Thermal inertia is low, which means that the radiator heats up and begins to transfer heat faster.
• Spacing in a lateral radiators compound may be of various sizes.
• Length up to 3 meters, and if the tube-type design, something more.
• The width of the steel used. Standard, it ranges from 1.15 to 2 mm.
• Appearance of modern steel radiatorova attractive. They do not require additional costs for the laths to disguise flaws.
• Weight is small, making it easy to assemble and install.
• Long service life.

How does a steel radiator

Water, heated to the desired temperature, is supplied to the working pressure of the boiler room, through the heating system. Radiator suitable for operating and test pressure. The second is higher than the first.

Then the water enters the radiator, which increases the temperature in the room.

Radiators are 2 connection type - unilateral and bilateral. When unilateral device connected to the pipes of the heating system on one side (hot water outlet and cooled). Such a scheme is realized in blocks of flats.

When the battery is connected to a bilateral construction of the heating system, a compound is cross or lower (feed from one side of the radiator, with water cooled withdrawal another). Diagonal (cross-sectional) embodiment involves connecting the inlet pipe at the top, and outlet coolant - bottom. This scheme is suitable for multiple-radiators.

The heating medium is distributed evenly over the area of ​​the battery, so the heat is increased. At lower joining two pipes, inlet and outlet, connected to the lower two nozzles. This provides an increase in heat output by 15-20%.

Types of steel radiators

Steel batteries exist 2 types, depending on their design - sectional and solid, which are divided into panels and tubular.

sectional

Not popular with consumers. Small demand generated low resistance to internal pressure. Such stand only 6 atmospheres.

solid tubular

They are more expensive and are used more for design solutions, rather than for practical use. They consist of pipes and resemble old cast iron radiators. No fins between the tubes, which facilitates cleaning, but will reduce heat transfer.

For the benefit of designers and spoke a variety of colors, in which color of this type of battery. Due to the rounded shape, such radiators are used in children's institutions, because they are the least traumatic.

Withstand higher pressure which is up to 22.5 atmTherefore resistance to pressure differentials higher than that of aluminum radiators. This is achieved by walls, whose width - 2 mm. Unique laser seam battery - provides insulation and is virtually invisible.

Collected in the form of vertical tubes, connected by the upper and lower headers. Them flowing coolant, which gives off heat radiator. He heats the surrounding air.

The cross-section allows to increase the length to almost any size. Maximum depth - 22.5 mm.

Minuses:

• Low heat dissipation are used only in small rooms or install long sections, which affects the price.
• Cost.

panel

Panel heating devices consist of one or more panels with channels for a coolant. In some models, there is ribbing. Sometimes they set the upper grille to hide the edges, which increases the appeal.
Design:

• 2 sheets of steel with the grooves made for the circulation of coolant.
• Several steel sheets with a U-shaped stamped in, which circulates the coolant.
• The back side comprises ribs which increase the heat transfer.
• The depth and location of the radiator mounting space heating uniformity depends.
• In the presence of a crane on the device, it is possible to pit the excess air from the heating system.
• Steel climato more practical if equipped with a thermostat.

The limit of the coolant temperature - 110 degrees. The height they are from 200 to 900 mm, and their length is 3 meters.

Ways to connect the panel heater: the side, universal, underwear.

Devices of this type are divided into types depending on the number of panels and ribs or convectors (U - shaped elements welded to the inner side of the radiator). Each of them is different heat settings.

• Type 10.

The simplest in design. It does not convectors. Handy when cleaning, there is little dust.

• Type 11.

10 is similar to the type, however, on the reverse side - ribbing that enhances the heat transfer. But the presence of the convector complicates cleaning.

• Type 20.

2 consists of panels without convector. It has grille air outlet.

• Type 21.

As in the 20 present two panels. Convector located therebetween. In the present design the upper casing covering the fins.

• Type 22.

2 consists of panels, between them has 2 convector. It has a top cover. Thanks to the compact design and good heat transfer common type of panel steel radiators.

• Type 3.

It contains 3 panels, but is not provided with the convector, not equipped with the upper case, which simplifies cleaning.

• Type 33.

Remember types of radiators can be according to the rule:

The first digit of a two digit number represents the number of panels, and the second - the presence of edges. Type 20 where "2" - the two plates, and "0" means no convector.

As tubular heaters panel type look aesthetically fit into any interior. Especially it relates to a compact and energy-intensive type 22.

Pros:

Advantage - integrity. Batteries require no preparation, pre-compound the parts together. They only need to hang. The advantages include improved heat transfer, because steel conducts heat well, and heaters that are installed between the plates, this parameter is increased significantly.

Cost of such a climate equipment reaches 40%. With a smaller amount of coolant in the embodiment heating occurs faster.

Minuses:

• Low resistance to frequent waterhammer, as the seams are welded panels which are not always kept them.
• Integrity. Despite the ease of installation, it is necessary to carefully carry such a device, as it requires maximum accuracy. When transporting the slightest damage leads to the fact that the radiator will be damaged before the target date.

disadvantages

Material

The steel is subject to corrosion, especially when the water is in contact with air. Manufacturers are struggling with this disease, an anti-corrosion layer covering radiators inside and outside the special powder paint. However, even the slightest defect coatings leads to early failure of the device.

Considering the water that flows through the pipes, it is - the problem. If you can live without water, the Gulf of other water - it is better to do it, then the likelihood of early failure will be reduced to a minimum.

Painting

It must protect the unit against corrosion. Not always manufacturers use the right materials for painting of steel radiators. Some of the types of paint can not withstand high temperatures, and the paint oblazit over time.

Manufacturers sometimes skimp on paint materials to the total cost of the heater was lower, and sales have increased. If the inner layer departs, then eventually the battery begins to "nibble" corrosion.

This manifests itself in the non-heating season, when the water pressure is not present, and in the design of the air bubbles are formed. Installation of such heaters do not need to comply with specific parameters.

Precautionary measures

• With self-assembly of steel panels, the valve opens gradually to prevent water hammer.
• The air valve is desired mounted in the upper opening.
• In spring and summer - fall period in the heating pipes a small amount of coolant. Heater without water should not be delayed more than 15 days per year.
• To transport, install, be stored carefully to avoid mechanical damage or chipping paint. Safeguard against moist environment and exposure to acidic and alkaline media.
• Take into account the recommended manufacturer of radiator coolant.
