Specifications steel radiators
To select a heat sink for the heating system, it is highly desirable to know the main technical parameters.Otherwise, you can not get the result that we would like.An important indicator of the radiators have not so much, so easily understand them, and lay people.Take, for example, steel radiators, the technical characteristics of which we discuss in this article.

design features and a variety of steel radiators
High technology does not require proof steel.This plastic, durable, flexible and malleable material lends itself well to welding, as well as a wonderful conductor of heat.So it is suitable for steel radiators in many ways.
Available steel radiators of two types:
panel type radiators
In the middle of this device are one, two or three panels.Each of them consists of two flat steel profiles welded together along the contour of the connection.The plates are stamped, and then they are formed oval vertical channels - paths for coolant.The production of these radiators is simple - seam welding connects the workpiece past stamping.Thereafter, the finished parts are held together by two pieces via nozzles.
device steel convector radiator.
To improve heat dissipation, manufacturers often equipped with panels from the inside edges of the U-shaped form.For their production are taken thinner sheet steel than for panels.The ribs contribute to the convection.If multiple series connected panels on both sides of the cover with their covers.Depending on the amount of heating and convector panels inside the radiator, there exist the following types.
Type 10 - is single-row radiator and convector without without facing.
Type 11 - single-row radiator with one convector without top grille.
Type 20 - double row without convector radiator with an air discharge grille.
Type 21 - double-row radiator with one convector fins, enclosed housing.
Type 22 - double-row radiator with two convector fins closed casing.
Type 30 - three-row, without convector fins, top closing.
Type 33 - three-row radiator with three convector fins closed casing.
How do you understand the type of sink will depend on its heat transfer.Type radiators 10 and 11 are not capable of convection and dissipate heat by only air heating.
Ready radiator obtained fairly narrow, which is very convenient for installation.The price of such articles is very democratic, so homeowners prefer to place them exactly.
radiators tubular type
steel tubes welded together, make up the core of the heater.However, he also serves as a housing.To produce such a heat sink is not as easy as the previous one, but the variations in the models he is undoubtedly much higher.The most common option is the classic radiator similar to iron, but with much more channels for coolant flow.
number of channels that can be tubular radiator.
worth such a device quite expensive, and it can not be called a budget option.It's more of an option for the designer is not constrained in the media.
all possible colors of pipe radiators.
his imagination, coupled with bright colors, original forms and the full range of sizes allows you to make such radiators real "highlight" of the stylish and beautiful interior.
And the price: any bimetal radiator known European brands cheaper than the tube, even produced in Russia.
most important characteristics of steel radiators
With heat output fared quite well - the heat transfer rate varies from 1200 to 1800 watts or more.Depends on the size of this parameter is the radiator, its brand and type of the model.Note that the biggest advantage of these devices is a low inertia.They heat up very quickly and begin to give a warm room.
The process of heat dissipation they occur in two ways - it is the direct heat radiation and heat transfer by convection.
operating pressure Maximum operating pressure in this type of radiator ranges from 6 to 10 atmospheres for plate radiators.This parameter is limited due to such steel properties as plasticity.However, the tubular type radiators can withstand more pressure - from 8 to 15 atmospheres.All this means that the steel radiators can not be used in district heating systems.They can not withstand the pressure of the central heating systems.
important detail is how "gentle" is about the quality of the coolant radiator.In order to become a real stumbling block - in fact it is so easy to rust in contact with water, air.However, the manufacturers do not give up - they are trying to overcome this problem.Apply a special internal coating for protection.Unfortunately, this often results in the fight corrosion victory.Therefore, radiators made of steel is better not put in an apartment high-rise building.In summer, the water will merge, and the rust will start to have radiators.
maximum hot water temperature that can withstand the steel battery - from 110 to 120 degrees.
Steel radiators may have both lateral and bottom connection.Wheelbase is important for radiators with lateral connection.It defines at what distance from the upper reservoir is low.This must be considered when mounting a radiator.Steel panel radiators depending on the model, type and manufacturer may have a spacing equal to the height of the radiator minus 50 - 70 cm. Tubular steel radiators spacing ranges n ranging from 120 mm to 2930 mm.
Now a few words can be said about the external parameters, in particular, about the size.Along the length of the panel type radiators may reach 3 meters, height of - 20 to 90 centimeters.Tubular radiators can be done almost any length, but its depth is limited by the size of 22.5 centimeters.The height varies from 19 to 300 centimeters.
thickness of steel.
At this rate, few people pay attention, but manufacturers for the manufacture of steel radiators used steel of varying thickness.This index may vary from 1.15 to 1.25 mm.It is understood that the thicker the steel the better.
Durability Due to the material manufacturing - durable and reliable steel - these radiators are able to live a long life, not to let their owners.Especially good are the high quality products with thick walls (0.12-0.15 cm), manufactured by reliable and responsible for its own brand products.
Ease of installation
Mounting data heaters is not very complicated.And it is very convenient that you can choose the type of radiator panel connecting both the side and bottom.In the latter case the tube may be hidden under the floor, and a temperature sensor is connected directly to the radiator.A panel of the radiator can be connected in series or in parallel - a sale can be seen both types of models.
Radiator panel type from the bottom system connection.
pluses and minuses of steel radiators
first about the merits
- have good heat transfer, which takes place not only by heating the air, but in the case of the panel-type radiators by convection.
- Because of the complexity of the design of these radiators are not, then break them nothing special.Thanks to this battery life is great.
- These radiators are lightweight, so they are convenient to mount.And always there are several mounting options - in fact produced a model with a variety of connection.
- standing radiators are cheaper than similar models of aluminum.
- Exterior steel radiators is very attractive, so they can become even interior decoration.
Now the drawbacks
- The biggest drawback - the inability to resist corrosion.Once the water stops flowing through the steel battery, she immediately begins to rust.Therefore, these radiators are absolutely not suitable for district heating systems, which are usually in the summer the water is drained for maintenance and repair.
- examining the characteristics of steel radiators, we can see that they can not withstand hammering.After all, they have welded parts, the joints are not maintained well and the increased pressure of pressing.The radiator can then lose shape and even to burst at the seams.Therefore, steel radiators can be used only in self-contained heating period.
- Unfortunately, sometimes the paint on steel radiators are not very high quality keeps bad.So after a few heating seasons occur peeling of the coating.
Manufacturers of steel radiators Radiators
In Russia, these radiators are not produced - it is very profitable for the buyer is the price of foreign-made products.It may be noted manufacturing companies from Germany - Buderus and Kermi, from the Czech Republic - Korado, from Finland - PURMO, from Italy - DeLonghi.Each firm has quite an arsenal radiators are different in height, length, depth, and thus the power.Therefore, these data need to look directly into the passport of a particular model of a radiator.Models huge quantities and to submit all their specifications in the framework of this material is very problematic.Therefore, for comparison, we take a radiator type 22 (has 2 panel convector fins, and 2) the size of 500/500 mm of some manufacturers.
Comparative characteristics of radiators type 22, 500 mm wide, 500 mm long popular manufacturers:
