Steel heating radiator (flat): design features of thin panel batteries, advantages and disadvantages of vertical wall types, as well as steel plate models. Metal heating radiators - a variety of options and their description

Cast iron batteries subtly reminiscent of the Soviet era and the typical design of almost every apartment. However, on modern market heating appliances, there is a pleasant alternative to the "accordions" familiar from childhood - flat old-style ones that weigh much less and look attractive thanks to special design. Due to the special fittings in such equipment, the joints between the structure itself and are invisible.

To create steel flat batteries for heating, two plates are taken interconnected by welding, made by conventional stamping. Between them there is a certain space called the "channel", where it subsequently falls. The design is also equipped with special pipes, to which heating elements are connected during installation.

Optional element The appearance of flat batteries can be ribs that increase the convection ability and heat transfer by about 60%. However, due to the extra space, these types of flat radiators will collect dust, which is why it is preferable to install them in rooms with strict sanitary conditions.

Flat battery device

In the classification of the flat type of the old sample, numbers are used that have their own meanings. The first digit in the description corresponds to the number of plates available, and the second to the number of elements with convection fins.

If 10 is indicated, then this is one plate that does not have ribs; 11 is one plate with a rib; 21 - two plates, moreover, one of them has a rib; 33 - three plates, all three are reinforced with a special rib. On the side of the flat radiators for heating there are details barred on top, everything is painted in White color.

Radiator Type Classification Table

In the most common delivery set of products, there should be fasteners designed for installation on brick walls. For other types of mounting surfaces, you will need to search separately in hardware stores. Also at steel heating there are usually four pipes designed to be connected to the system. The battery plates are connected either directly to the riser, or they are fixed with the participation of special fittings.

There are also flat-plate batteries in specialized stores with a built-in kit for connecting a thermostatic valve. This insert with a thermostatic head is used to control the rate of water movement inside the battery.

The default location for this add-on is Right side, however, when a special order is received, the manufacturer is able to “unfold” the part in a mirror image for the convenience of the client.

To make rooms more aesthetically pleasing attractive appearance, you can opt for narrow horizontal radiators manufactured by many manufacturers. They are equipped with connections to the heating system in the middle and may have a valve insert. If there is a built-in kit, such things can be connected to the heating system through lower part, after hiding the pipes in the wall.

One of the most important criteria choice of flat heating radiators for decoration and space heating are room design, type heating system houses and value complete set for mounting the device.

The most common and trivial is such a design in which the pipes either go along the wall or are carefully hidden in it. For it, flat radiators were created, equipped with a side connection design. flat batteries may be different. If the heating pipes run in the floor, then it is necessary to choose a battery with a connection from below.

Floor and wall connection

How to install the heating element correctly

For heating systems operating on the principle of a heat carrier through pipes with the participation of pumps, thin batteries made of steel are taken. In systems based on the principle of gravity, component thin products are used.

Connection to the heating system

For thin, flat plate radiators, closed heating systems equipped with a special one will be the best habitat. The connection of the structures under consideration to open systems is categorically not recommended due to the high probability of damage to the radiator and a decrease in its service life.

In addition, it is contraindicated to drain the water from the system too often, replacing it with fresh water. This recommendation is due to the increased oxygen content in fresh water, which leads to an increased corrosive effect on radiators and other elements of the heating structure. Also, it should be avoided in rooms where it is predicted increased content moisture in the air - for example, in the bathroom - due to the same risk of rusting.

Flat radiators are installed in systems equipped or metal. Therefore, you should definitely attend to the installation of an anti-diffusion barrier. It will help save the system from unwanted and destructive oxygen.

Before you buy and install flat batteries, you should very carefully and thoughtfully examine the performance of the heating system laid in the house. If available, equipped with a special protective valve, required pressure water can be kept at a level of no more than 2.5 - 3.0 bar.

The best option in case of changing old heaters to new ones is to invite specialists who will calculate all the characteristics, taking into account the features of new modern radiators.

Today, the consumer may be at a dead end when choosing equipment home heating, all because manufacturers provide this market with a huge variety. It is then when "eyes run wide" and the question arises, which one is the best? In this article, we want to consider flat heating radiators as the most popular and optimal in terms of cost and quality.

What is a flat radiator

Let's start the description, of course, with positive qualities this appliance:

• The flat shape allows you to significantly increase the free space in the house.
• Due to its shape, the window sill can also be set to a much smaller size (if necessary).
• Smaller area to collect dust and dirt.
• Facilitation of cleaning from contaminants (in relation to batteries with sections).
• Attractive and unusual appearance which is easier to fit into the interior.

The next question is how well does a flat single-row heating radiator handle heat supply?

We all know that the amount of heat directly depends on the size of the battery. The first conclusion that can be drawn on the basis of visual perception is that the radiator area is decreasing, which means that heat transfer is also decreasing. But this is only a first look at the situation, there are some tricks that allow such a device to lead the market.

Let's start studying flat thin heating radiators from their depth. There is no clear indicator that indicates the subtlety of the device, it can be determined “by eye”. At the same time, we take for the standard. A flat, or as it is also called, a panel radiator, will be about two times thinner.

Having made an overview of all models of heating devices existing on the market, we conclude that only a steel flat heating radiator is suitable for the standards of panel radiators, and we will consider it in more detail.

Interesting!
With its small thickness and stylish appearance, the panel radiator owes special technology which is used in its manufacture.

• The radiator is made of stamped steel sheet.
• A solid sheet with a good recess area is taken as the basis.
• Due to the small area of ​​\u200b\u200bthe product, heat transfer will be small.
• Due to the fact that the design is not sectional, but flat over the entire area of ​​the device, a large heat output is achieved.
• The two previous points give their plus - much less energy is spent on heating the radiator.

Important!
Manufacturers have taken care of those who simply need increased heat transfer by developing an addition to the design itself - a finning system (convection fins).
Such ribs are welded using spot welding over the entire area of ​​\u200b\u200bthe radiator.
The main shape of such ribs is considered to be trapezoidal.

Types of panel radiators

All industries use the same classification of panel radiators.

There are five varieties in total:

• Type No. 10. Ordinary panel (stamped) without any frills. This option is one of the most common types of the “flattest panel radiator for heating” category - the depth of this battery is 46 millimeters. The best-selling model of this series is Kermi.

• Type No. 11. Panels of this type have one layer of convection fins, the depth of such a radiator grows to 59 millimeters.
• Type No. 12. This is a complicated design, which consists of two flat panels separated by a finning system. The thickness of this design is 64 mm.
• Type No. 22. This is an even more complex design, which consists of two panels and two finning systems that are located between the planes. The depth of this device is 102 millimeters.

• Type No. 33. This is the most complex of structures, consisting of three planes. Between the first two panels, two sections of ribs are installed at once, and one more between the second and third panels. The depth is complex design will reach 157 millimeters.

Note!
The designation "flat steel radiator" does not fit the last two options.

Some manufacturers allow varying the depth in both directions, but not more than 10 millimeters.

Important!
All models of panel radiators (with the exception of type 10) are equipped with an upper grille and side walls for protection.
This greatly improves the aesthetic appearance of the battery, but also increases its price.

• If you have chosen a flat oil cooler for yourself, do not try to install it yourself even if you have detailed instructions necessary actions. The heating system is a rather serious thing, so leave this work to specialists.
• Due to the fact that panel batteries for heating do not have a very large area of ​​\u200b\u200bthe coolant, experts do not recommend installing them in a system with natural circulation hot water. Most best option for such radiators - a system with forced circulation using a pump.
• If you are using a forced water circulation system, do not forget that it must be closed. To do this, you must install an expansion membrane tank.
• Frequent draining of fluid from the heating system is not recommended.. Together with the pouring of clean and fresh water, oxygen will certainly enter the system, which can adversely affect the steel product. Despite the fact that manufacturers are taking some precautionary measures, it's still not worth the risk.
• Also, experts do not recommend installing in rooms with high humidity , since this makes it more likely that metal structure corrosion may occur.
• It must be remembered that each layer of the finning system on the panels is an additional, hard-to-reach place for dust and dirt accumulation during cleaning.

Conclusion

The convenience and practicality of the models we have described are undeniable in many cases, but it is up to you to decide whether to use such heating devices in your homes or not. The best option is the recommendations of a specialist who will be able to assess the situation locally and make his verdict (in most cases this applies to private suburban buildings).

In the presented video in this article you will find Additional information on this topic.

When a consumer opts for steel radiators when replacing old ones, this is a completely reasonable and profitable decision in many respects.

Panel, as well as steel lamellar heating radiators, have a number of advantages that make them very popular not only in the domestic market, but also in the world, and this is primarily due to the technology of their production.

Steel heating radiator (flat): design features

As you know, steel perfectly transmits heat, and this is the first and most important sign of good heating devices. Steel (flat) heating radiator is made of sheet steel highest quality not less than 1.2 mm thick.

The reputation of this metal is not too high when it comes to its poor resistance to corrosion, and hence to a particularly reverent "relationship" with the carrier. It used to be so, but, unfortunately, this stereotype is still alive in the minds of consumers.

Modern manufacturers have learned to bypass weak sides steel, processing products with special anti-corrosion compounds.

Thin panel radiators also look no less interesting, since the principle of their manufacture has changed slightly for the better:

Choosing a flat steel radiator as a heater in an apartment, Special attention should be given to the method of its coloring. This information is indicated in the data sheet of each product. It is on what technology was used, and how well it was produced, that the durability of the structure depends. The best method is considered to be cathodic electrophoresis, which not only gives the product a beautiful presentation, but also protects against corrosion and mechanical damage.

In addition to the method of painting, the product data sheet indicates the pressure under which it was tested. This is another important factor, since a steel flat heating battery that has withstood a load of 13 atmospheres is guaranteed to last 10-15 years.

Battery classification

As even non-specialists know, than more area heater, the more powerful it is, which means it heats the room faster. A stamped steel heating radiator can be effective not only because of its size.

For greater heat transfer, convectors are connected to some models of panel batteries, the task of which is to distribute heated air throughout the room.

Thus, these heaters are divided into the following types:

1. Single panel, consisting only of the main element and mounting fittings. Such a radiator is good where the window does not cause heat loss. This product is issued under the number 10.
2. Single panel with heat exchanger- this model is more powerful, as it has ribs. It is number 11 in the classification table. As a rule, the first and second options are the most inexpensive types of products.
3. Two panel radiators can also consist either only of the main elements ( type 20), or 1 or 2 fins are added to them ( 21 and 22 respectively). The latter are the best option in terms of price and performance.
4. Three panel models are equipped with three elements and convectors ( type 33). These are the most powerful, heavier and more expensive products.

Each of the listed types of batteries is good, the main thing is that the heating system and the area of ​​\u200b\u200bthe room correspond to their technical characteristics. It is common for class 21, 22 and 33 radiators to have side and top shrouds that give them a more stylish look.

Size to power ratio

How correctly, all types of steel radiators are divided not only by their type, but also by their dimensions - height and length, on which their power depends.

For example, products of types 10 and 11 with a height of 300 mm and a length of 400 mm have the lowest heat transfer - only 265 W, while with the same dimensions for a model of type 21, it is 370 W, and for the 22nd - 476, respectively.

The height of steel panel radiators varies from 300 mm (the smallest) to 600 mm, and the length from 400 mm to 3000 mm.

Thus, it is possible to calculate what size and type of radiator to purchase for each individual room, taking into account the heat loss in it and its area.

Vertical Models

In addition to the usual batteries, usually mounted under the window, there are such interesting design options as vertical panel heating radiators. They are characterized by a large height - from 1000 mm and above.

Such batteries are most often used as an addition or decoration to the interior of a room with the possibility of quality heating(please do not confuse them with tall panel radiators up to 900 mm high).

As a rule, a vertical panel radiator with a bottom connection type is more popular, as it can be installed in any free corner or near a wall, in a niche or partition.

This allows you to save living space and give the room a more aesthetic appearance by removing all pipes into the floor. In addition, air heating at human height is considered more efficient. Such models can stand on beautiful decorative legs or hang on the wall, be a mirror decoration and be useful as a hanger or towel holder.

A wall-mounted panel radiator can be made to order and have either a strict classic monochromatic look, or contain images or various colors on its surface.

Not all manufacturers produce similar designs, so you should immediately be prepared that they have a high cost.

The disadvantages of vertical radiators include the fact that they can create air cushion in the room, especially for wall models. They are quite difficult to mount, so you can’t do without specialists, especially when you consider that with the slightest mistake they will heat up unevenly, thereby reducing their efficiency.

The heat in the apartment should prevail over the beauty of the interior, so you should weigh all the pros and cons of vertical heating radiators and find the most compromise solution.

Pros and cons of the device

If we consider steel batteries as heating devices in an apartment with a centralized heating system, then it is better to study their shortcomings well so as not to regret the consequences:

1. Panel radiators can withstand atmospheric pressure from 6 to 10 bar, while differences in the system can reach 15 bar. A leak or a breakthrough may not immediately occur, but if such jumps are frequent, which can be found out from the managing organization, then it is worth refusing to install them.
2. The quality of the coolant is also important. AT centralized system heating, adapted for cast-iron sectional batteries, its cleanliness does not matter, although many owners of such structures know that over time even they become clogged. Inside the panels are the channels through which the media moves, and they are small enough to allow suspension and debris to pass through. Such a battery will clog faster and fail, and since it is one-piece, the entire panel will have to be changed.
3. If she stays on long time without carrier, for example, on summer season, then steel will corrode. That is why manufacturers recommend these batteries for autonomous systems heating.

There is some good news about these radiators:

1. They are easy to mount.
2. They have high level heat transfer, especially for models with convectors, for example, steel panel radiators (RVS 21 or any other type). How larger size panels, the warmer the room will be, provided that the calculations have been made correctly.
3. A small amount of media inside the system saves a lot of money because it is easier and faster to heat up.
4. They are safe because they do not have sharp edges.
5. They have a stylish look.

Panel radiators are the best heater option for autonomous heating systems according to affordable price and in a stylish way.

Steel plate radiators

Panels are far from the only battery option. Also in Soviet years cast-iron "accordions" were replaced by a plate steel radiator. Most often it could be found in state institutions and entrances of apartment buildings.

At the heart of lamellar steel radiators from pipes, a tube on which plates for heat exchange are “strung”. Modern models little like those that were in the days of the USSR, and their efficiency is an order of magnitude higher.

A clear advantage of such batteries is their ability to withstand pressure in the system up to 20 atmospheres. Hot water under such strong pressure moves through the pipes, they heat up and give part of their heat to the plates. Since they are in contact with air with their surface, they heat it up quickly enough.

These types of steel radiators are of low cost. Among their shortcomings are unpresentable appearance, and if the heat exchanger plates are open, then also rapid pollution , which is probably why they are still installed in state institutions, and not in private homes.

In conclusion, we can say that the advantages of steel panel radiators are much greater than the disadvantages, and even for district heating you can choose a model that matches its parameters. To really know that the selected type is suitable, it is better to let a specialist make all the calculations for its power and efficiency, and correctly integrate it into the system.

Preparing for the winter cold, the owners of their own homes are worried about the health and good operation of the heating system. Flat radiators are devices with an extraordinary body, somewhat reminiscent of cast iron, but much lighter in weight, and the owners of country houses pay the most attention to them.

Design

They make flat radiators from steel, equipping them inside with special fins that hold high temperature power. Joints and connections with pipes are practically invisible due to the use of special fittings.

Flat batteries are not standard, are available various shapes, height and depth. Heat is transferred through radiation.

Forms of designs of batteries and radiators:

• single row or multi-row,
• flat compact,
• front side is smooth
• the surface is profiled on all sides or only on one side,
• with or without a rib element,
• with thermostatic valve.

For heating, they are represented by two plates fastened by welding. They are made by stamping. The heat carrier is placed between them; there is a special channel for it inside. Radiators are connected to the heating system with special pipes.

Variety of designs of flat radiators

If you use a special connection, then flat heating radiators can be formed from several plates. The presence of convector fins on each of them increases the heat transfer. The power parameters of a flat radiator equipped with a ribbed surface inside will be half as much. There will be much more dust on these devices, so they are installed in buildings with high sanitary standards. As you can see, the design flat shape batteries is not complicated.

Classification

When classifying batteries for heating, numbers are used, the first of which indicates the number of plate sheets, the second - the number of ribs:

• The figure shows that the plate is one and the complete absence of ribs.
• One lamellar sheet, supplemented with a rib structure.
• Two lamellar sheets, one equipped with convection fins.
• Three laminar sheets, all connected with ribs.

Classification of flat radiators

An additional part of flat batteries is the upper grill, which has side cases on both sides. As a rule, she white color. The battery packaging kit is supplemented with fasteners. Wall partitions made of different material, need different means mounts. If the packaging kit is supplemented with the wrong fasteners that are needed in a particular case, you will have to purchase others on your own.

Flat ones are equipped with four connection pipes. This makes it possible to connect the device to the entire heating system from any side. As a rule, they are connected directly to or using specially designed fittings.

There are flat steel radiators equipped with a thermostatic valve. It adjusts the fluid inside the product. Its connection is right-handed, in order to connect on the left, you need to make a special order.

Some manufacturers of flat batteries and radiators for heating create horizontal models connecting to the wall surface in the middle. A valve insert is not required. In order to make a connection from below, hiding in the floor, the packaging set must be integrated. There are connecting parts that are hidden in the walls.

When choosing, consider the price of the product, the design of the room, the building, the type or type of heating in general. Standard systems heaters require a side connection, if the pipes run under the floor, use the bottom connections.

Mounting

A flat radiator is used for rooms with forced circulation of the heat carrier, that is, where circulation pumps are used.

The heating system using a flat battery is closed structure and contains a membrane expansion tank. She looks about in the following way: the heat carrier under the influence of the pump goes through the direct pipeline, passes through the valve and then goes to the heat consumer, then passing through the vent, goes through the return pipeline to . And from there the process is repeated again.

Scheme closed system heating with flat radiators

If the installation of flat batteries applies open system, battery life will be significantly reduced. There is often no need to drain the water. Freshly poured liquid always has a high oxygen content, which will lead to corrosion on the radiator. It is not recommended to install thin devices in rooms with high air humidity, such as a bathroom. If you follow all the requirements and recommendations, the risk of corrosion is minimal.

It is possible to install flat radiators with your own hands one after another, in which case the heat output will decrease by forty percent per meter, since heat transfer through radiation after the second row will decrease. If you install them in rows and equip them with plates on top, you get a design that looks like one apparatus.

The flat battery is closed device flat type, along which the heat carrier moves.

When a battery device is used for a system with pipes made of plastic or metal, an anti-diffusion barrier must be installed. It will protect against exposure to oxygen masses.

Before you buy flat batteries, read the technical specifications flat device batteries, whether they are suitable for this building. So, for example, when used in a building with a safety valve, the liquid pressure should be maximum 3.0 bar.

Pay attention to the temperature of the water in the pipes.

The one who decides to change the radiators, throw out the obsolete ones and install new ones, argues incorrectly. Before buying new radiators for heating, you need to make accurate calculations, take into account the characteristics of the building, the design of the installed or already existing system, technical specification devices, entrust the installation to specialists.

A huge variety of heating devices that are present on the modern market for heating equipment often confuses consumers. After all, the question of which is better torments precisely when the eyes run wide. This article will deal with heating radiators - “flat”. Why is this topic so interesting now? Judge for yourself.

• First of all, flat design heater is an increase in free space in the room. Accordingly, it becomes possible to install a window sill of a smaller width.
• Secondly, it is a reduction in the dust collection plane.
• Thirdly, it is an unusual and attractive appearance.

But here the question arises: what about heat transfer? After all, it is no secret that this indicator largely depends on the size of the heating battery. That's right, the heat transfer rate is decreasing, but it is not in vain that manufacturers produce these devices, which means that there is some kind of trick that maintains the radiator power in required amount. All these questions will be dealt with here.

What are flat radiators

start talking about flat batteries heating is necessary with their depth size. There is no exact indicator that would indicate the subtlety of the device. It is mostly determined by eye. For example, a cast-iron radiator can be taken as a standard - this is a common design. Anything that is less than half its depth can be attributed to flat heating radiators.

If we make an overview of all existing models, then only steel panel batteries are suitable for this standard. We will consider them. Why does it happen that panel structures have a small thickness? It's all about the technology of their manufacture.

These are devices made of steel stamped sheets. The form is based on a single sheet with enough large area deepening. That is, it is not sectional construction, and flat in the entire area of ​​​​the heater itself. This is what is achieved by increasing the heat output. But at the same time, the depth of each panel is not very large, and, accordingly, the volume of coolant used in the heating system in the flattest radiator will be small. This ratio has a definite plus - a small fuel consumption for heating the coolant. That is, these two quantities are directly proportional.

flat battery

Manufacturers have gone further. They did not go in cycles in devices with a purely panel form, because, as mentioned above, this form has a reduced power. To increase this indicator, additions were made to the structure itself in the form of a finning system, the so-called convection fins. They are welded over the entire area of ​​​​the battery by the method spot welding. The main shape of the ribs is trapezoidal.

Types of flat radiators

The classification of flat radiators for all manufacturers is the same. There are five types in total: 10, 11, 12, 22 and 33. How do they differ from each other?

• Type 10 is just a stamped panel with no frills. If we talk about the category "the thinnest heating radiators", then this type is the basis of this category. You won't find thinner on the market. Let's look at the type using the example of Kermi radiators. So type 10 has a depth of 46 mm.
• Type 11 is one panel with one layer of finning system. The depth of this model is 59 mm. Calmly and it can be classified as "flat".
• Type 12 - these are two panels, between which convection ribs are installed. Its thickness is 64 mm.
• Type 22 is a design consisting of two panels and two fin systems that are located between the planes of the panel. Depth - 102 mm.
• Type 33 is three panels. Two layers of ribs are installed between the first two, and one layer between the second and third. Depth 157 mm.

For other manufacturers, the depth size may vary in the same range with slight deviations in one direction or another. The deviations are insignificant, so the dimensions of the Kermi heating radiators can be taken as the basis for our analysis.

Attention! All types of steel panel radiators, except type 10, are supplied with protective side walls and a top grate. This improves the appearance of the device, but increases its cost. And one more thing, the convection fins are a real dust collector, which is very difficult to clean.

And now let's choose from this type those heating appliances, which can be included in the category of "flat". Let's start with the depth cast iron radiator ChM-140 - 140 mm. This is what we will deviate from.

You can immediately determine that the first three types, and these are 10, 11 and 12, are thin. But 22 and 33 are not included in this category. That is, it turns out that not all steel panel heating radiators can be considered flat.

Type 12

• Due to the fact that flat heating radiators contain a small amount of coolant, install them in systems with natural circulation hot water is not recommended. For them, the best option is heating with forced circulation, where the pump is installed.
• And since this system forced, which means it must be closed, where the membrane expansion tank is installed.
• Often it is not recommended to drain the coolant from the heating system. With new filling pure water along with it, oxygen enters the network, which negatively affects steel products. And although protective measures manufacturers carried out, anyway negative impact oxygen provides.
• Install the thinnest radiators in wet rooms not worth it. This is an increase in the risk of corrosion of metals.
