The current market for appliances designed for space heating is very saturated. You are invited to just a huge number of different devices that have different qualities, perform a different set of functions. In this article you will learn what panel steel radiators are, how they work, what is good. You will also have the opportunity to understand how to connect such equipment to your heating system.
What is a product?
Panel steel radiators are special heating devices that have an average degree of thermal conductivity compared to units made of other materials.
These devices are made of very high-quality steel, which is previously protected by special means against corrosion. Such radiators may have fins or be manufactured without them. Such devices are used in closed and autonomous heating systems, in which a reduced oxygen content in the coolant is noted.
Design and principle of operation of the apparatus
Panel steel radiators have a fairly simple device. The first layer is stamped steel sheets. They have a small thickness, are quite durable, resistant to corrosion even in the event of contact with the liquid. In these sheets, small channels are made through which the coolant circulates.
Next is the crate, which is designed to increase heat transfer. These panels have a certain relief in the form of the letter "P". The very last layer is represented by decorative panels that ennoble the appearance of the unit.
Inside the radiator there is a coolant that circulates through channels interconnected. It should be said that the coolant is represented in a relatively small amount. This principle of operation allows you to quickly heat the room.
Device benefits
Panel steel radiators have the following advantages:
1. Attractive appearance. Modern designers offer a lot of solutions that will help organically fit these devices into your interior.
2. High degree of heat transfer. The fact is that steel conducts heat very well.
3. Integrity. It should be noted that after buying the device in the store, it should not be additionally collected. It is already fully ready for installation.
4. Profitability. The fact is that the radiator does not require a large amount of coolant, therefore it heats up much faster than other devices. In addition, the device is equipped with a temperature controller.
5. Light weight. Thanks to this wall, the heating system does not experience too much stress.
6. Availability.
7. Great variety.
Panel steel heating radiators are quite effective devices that can provide good work in autonomous systems.
disadvantages
Unfortunately, these products have certain disadvantages:
- Low degree of corrosion resistance, especially if the steel is scratched.
- Since the pipes that have been installed for a long time inside contain certain debris and dirt, the channels inside the radiator can quickly become clogged.
- Do not install such equipment on central heating systems, where the water pressure is very high. It can simply “tear” the device.
- Panel steel radiators must be transported very carefully.
- Low resistance to water hammer.
Damaged steel radiators will be thrown away entirely. You will not succeed in replacing anything in them.
Specifications
Consideration should be given to the quality of the device as claimed by the manufacturers.
So, these devices have such technical characteristics:
1. Dimensions : height - 30-90 cm, width - 40-300 cm.
2. The temperature of the coolant is up to 110 degrees.
3. Working pressure - no more than 10 bar.
4. Testing pressure - about 13 bar.
Device classification
If you need steel panel radiators (you already know the characteristics), then you must also understand their types.
A type | Characteristic |
10 | They consist only of a heating panel. There are no ribs or gratings in this type of device. There is no convection in the apparatus, and, therefore, dust. Such an apparatus is used where cleanliness is very important (hospitals, child care facilities). The radiator is also very easy to clean. |
eleven | Such a product is characterized by one row of panels. However, it has ribs on the back. The upper grill is completely missing. The advantage of such a device is its quick heating. However, its purity must be monitored more carefully. |
20 | This unit has two panels. There are no ribs on it. A grill is provided for air outlet. Double-row models have more power, so they work more efficiently. |
21 | In this case, there are two panels between which there is convector fins. A distinctive feature of such an apparatus is the presence of a casing with which the radiator closes from above. |
22 | Such a product is characterized by two panels, a convector is welded to each of them. This type of radiator is considered the most popular. |
thirty | There are three panels without convectors. Such a radiator is closed from above using a grill. |
33 | Such steel panel radiators PCB2 1 are the most powerful. There are 3 rows of panels, as well as three convectors. The device is covered by a casing at the top. Naturally, the device is very demanding in maintenance and cleaning. |
These types of steel panel radiators are the most common.
Features of the choice of unit
The presented products will work efficiently if you choose them correctly. First of all, you should pay attention to the power that must be correctly calculated. For example, steel panel single-row radiators should be used in small rooms. The fact is that they have minimal power.
Naturally, it is also necessary to take into account the quality of the product. To do this, focus on the reputation of the manufacturer and reviews of other customers. Today, Kermi steel panel radiators are considered very popular. In addition, there are such manufacturers: "Corado", "Demrad". Here's what to consider when choosing a steel panel radiator. Russia produces such devices is not yet sufficiently active.
Pay attention to the size of the device. It all depends on the capabilities and dimensions of your premises. Naturally, the type of connection is an important selection criterion. Here it is already necessary to take into account the structural features of your heating system.
And the last: do not buy heaters in those stores that refuse to provide you with a quality certificate and other supporting documents. Otherwise, you just wasting your money.
Ways to connect the device
There are only two of them. There is a side connection of steel panel radiators or lower. It all depends on your heating system, as well as the model of the heater itself. If you have a device with a side connection, then you will connect it to the pipe on the left or on the right. Such an installation can be done independently, since it does not cause any difficulties.
As for the lower connection method, it is more preferable if it is necessary to adjust the heating of the room manually. In addition, this type of connection makes it possible to hide the supply pipes. Naturally, the price of a device with a lower connection is higher.
Connection Instructions
It consists of several stages:
1. Unpack the steel panel radiator, but do not remove the protective film from it.
2. Make sure that the fasteners are installed at a distance specified by the manufacturers from the floor (10 cm), wall (4 cm), window sill (minimum 6 cm). Only in this case can maximum efficiency be achieved.
3. Install the device by screwing it to the supply pipes. To do this, use dowels, nuts with washers, fasteners, a plug and keys to tighten the lock and to bleed air.
4. Open the central radiator tap.
5. Turn on the heating system and check if the product is warming. If it remains cold, then you need to let all the air out of it so that the radiator is filled with coolant.
Device manufacturing technology
The production of steel panel radiators consists of several stages:
- Pressing sheet steel and further stamping panels. Their thickness should not exceed 1.25 mm.
- Production of convectors in the shape of the letter "P". Steel is also used for this.
- Joining sheets in the panel using roller welding.
- Fixation of convectors.
- Application of paints and varnishes (first the surface is primed and then painted). And here it is necessary to use such substances that will be safe for humans and will not respond to temperature changes.
Features of the operation of the device
It should be noted that panel steel heating radiators are distinguished by relative fragility and tenderness. Therefore, there are some operating rules that must be followed in order for the product to be effective and last as long as possible. So, follow these requirements:
1. Do not allow the presented devices to hit with something, especially during transportation.
2. Do not unpack the brought device before you finish painting the room.
3. Avoid draining fluid from the radiator. To do this, do not open the taps on the product. This will help you avoid quick metal corrosion.
4. The operating temperature of the device should not fall below 0 degrees.
5. Do not also cover the apparatus, as this makes it less effective. The fact is that in this case, air circulation worsens.
6. Do not use hard sponges to clean the panels. Use soft wipes and detergent best. Cleaning powders can damage the paint and contribute to metal rusting.
In principle, following this instruction will help you not to worry about the integrity and safety of your heater. Naturally, you should also read the instructions for use, which is included with the unit. That's all the features of panel steel radiators. Good luck
