Plate heating radiator: features of old steel appliances, video instructions and photos

In apartments of the housing stock created several decades ago, and in many private houses, there are batteries manufactured in the same years. Over such a period of operation, their characteristics have deteriorated and one should not expect complete heat transfer from them. While it is easy to update the appearance of radiators, restoring normal operation is sometimes impossible. When planning repairs, it is worth understanding whether the old heating batteries will continue to serve or whether it is better to replace them.

What are plate heating radiators?

What parts does a plate heating battery consist of?

Plate radiators are a type of convector heating equipment. They are characterized by a large area of ​​the heat exchange part and a minimum number of pipes through which the coolant circulates.

The operating diagram of the device is very simple:

• the coolant under increased pressure is driven through thin pipes of the heating element, giving them its thermal energy;
• the temperature of the metal plates strung on the pipes increases from the heated pipes in a short period of time;
• the air temperature rises quickly between the heated plates;
• light heated air rises up to the ceiling of the room, displacing cold air;
• cold air descends to the convector, where between its plates it increases its temperature.

Unlike other heating devices, plate radiators do not heat the room due to thermal radiation (IR waves), since their surface temperature does not rise to the desired level. Such batteries raise the air temperature in the room only due to air convection.

To maintain the air temperature in the room using a plate convector, you need to remember the feature of the device. Since the pipes of the heating device have a small diameter, the amount of coolant that passes through them per unit time will be insufficient to quickly increase the temperature of the plates. That is why in the heating system where the above equipment is installed, the coolant must circulate under high pressure and be at a high temperature. This will quickly increase the temperature of the plates, and therefore ensure good air convection.

How to increase the efficiency of a heating device? A metal corrugation attached like a protective panel will help increase the power of a plate radiator. This corrugation increases the useful area of ​​the heating element, which is involved in heat exchange. This is why the volume of air that can pass through the convector increases and increases its temperature.

Old plate heating radiators warmed the room due to natural air circulation. As a result, a sharp temperature difference was observed in a large room. It was always warmer at the top than at the floor. The built-in fan helped solve this problem. Modern plate batteries are now classified as volatile equipment (the fan runs on electricity). But in this case, the efficiency of the device increases due to artificial air circulation.

Types of equipment. As can be seen from the photo, plate heating radiators primarily differ from each other in their construction materials.

Today you can buy the following radiators:

• steel - plates and pipes are made of steel. The device is characterized by increased strength and is resistant to water hammer. However, it has a low heat transfer rate;
• copper - if all parts are made of copper, then the battery will have high power and
  Made of copper.

  high heat transfer rate. But its cost will also be high. Therefore, plates made of cheap metals (steel) are most often hung on copper tubes;

• aluminum - they are inexpensive, can quickly raise the air temperature to the desired level, but are not durable. It is not recommended to use them in a central heating circuit. Most often, aluminum pipes are replaced with copper ones, which increases the strength of the device and its cost.

New and old plate heating radiators may differ in the number of workers

Made of aluminum.

contours and convection panels. So, if devices have one circuit and one set of plates, it is designated as device 11. Accordingly, class 22 indicates 2 coils and 2 sets of plates. There is class 21, where there is 1 coil for 2 rows of plates.

In the photo, plate heating radiators can be of various sizes. It is thanks to the variety of sizes that the buyer can choose a product that best suits the parameters of the room and interior design.

Washing cast iron radiators

Despite their reliability and durability, cast iron heating radiators are recommended to be washed and cleaned periodically.

Important! To avoid emergency situations, flushing is carried out only after the end of the heating season.

18-section radiator.

• The flushing process begins with draining the coolant from the heating system.
• Each radiator has an end cap that is unscrewed, and in its place a radiator cap with an ordinary ball valve is screwed in.

Advice! When flushing the heating device, it is also recommended to replace the old tap on the radiator supply. There is a high probability that over time the passage channel of the faucet has narrowed significantly or is completely clogged.

• Next, a compressor comes into play, which is connected to the battery, while it is shut off from the rest of the heating system by a ball valve. A special gun with a piston is installed between the compressor and the battery.
• The compressor pumps up a pressure of 15 atmospheres to the piston, after which the trigger is pulled on the gun and the pressure “goes” into the radiator. The pressure removes the layer of sediment and turns it into dust, which is sent down the drain through a rubber hose (also connected to the gun).

Important! When you pull the trigger of the gun, the ball valve on the rubber hose must be closed, in which case all the pressure will go to the radiator. A few seconds after pressing the trigger, you need to open the tap on the rubber hose.

• The process is repeated several times until more or less clean water flows out.

Design features of plate radiators

Modern plate convectors are designed with the same simplicity of design as the previous “Soviet” models.

Such radiators consist of the following structural elements:

• A curved - most often U-shaped - piece of pipe, at the ends of which two ball valves are installed.
• A set of plates “strung” on a pipe. Moreover, in most cases, the plates are made of the same material as the pipes.
• Protective casing - a metal box with an open top and bottom. Moreover, inside the casing you can accommodate not just one piece of pipe (thread), but several such “packages” at once.

Sectional and plate batteries arranged in a similar way operate according to the following scheme:

• The coolant moves through the pipe under high pressure, practically without cooling.
• Thin plates heat up to high temperatures in just a matter of seconds.
• The temperature of the air inside the case instantly rises by several degrees.
• Warm air rises up through the perforations in the casing cover, and cold air is “sucked” into the housing through holes in the bottom.

As a result, plate heating radiators provide a high rate of thermal convection of air masses, warming up a small room in literally a matter of minutes. However, when heating really large rooms, naturally convection will not be enough. In this case, a tangential fan is installed on the bottom side of the plate convector housing, providing forced convection .

Design and principle of operation of the radiator

Moreover, the intake of air masses is carried out not from the bottom, but through the perforations in the lower part of the side edges of the casing, which makes it possible to “drown” the plate battery in the floor slab, leaving only the upper grid at the level of the floor covering.

Advantages and disadvantages of plate batteries

The undoubted advantage of such heating devices is their high structural strength.

Through such a radiator, coolant can be pumped under a pressure of 20 atmospheres or more - the strength of the structure depends only on the annular rigidity of the pipe, which can withstand pressures of up to 40 bar.

In addition, such a radiator will not leak - it has no internal joints. Other advantages include low cost and good compatibility with cheap thermostats, the operating principle of which is based on dosing the flow of coolant into the heating device.

The obvious “disadvantages” of such heating devices include, firstly, the uniformity of the exterior, the shape of which is determined by the contours of the box-shaped casing, and, secondly, the loss of thermal power due to contact with dust - a significantly smaller volume of air passes through the “clogged” plates.

However, both drawbacks can be easily eliminated - the box-shaped body can be “recessed” into the floor covering or designed as a baseboard, and dust can be easily cleaned with a regular vacuum cleaner.

Types of plate radiators

The classification of the range of plate batteries in most cases is organized according to the following design features:

• By type of pipe and plate material.
• According to the number of “threads” in the casing body.
• According to the diagram for connecting the radiator to the wiring.
• According to the scheme of fastening the casing to the supporting surface.

Based on the first method of classification - Based on the type of material of the pipe and plates - we can distinguish the following types of batteries:

• Steel plate radiators, the main elements of which are made of the same metal. Such heating devices are relatively cheap, but their thermal output leaves much to be desired. Therefore, in combination with high-strength steel tubes, it is customary to use plates made of metals with higher thermal conductivity.
• Copper plate batteries, the elements of which are made of this non-ferrous metal. This radiator provides maximum thermal output. However, not all homeowners can afford such products. Therefore, to reduce the cost of construction, only internal pipes are made from copper, onto which plates of cheaper metal are strung.

Copper plate radiator

The second method of classification - according to the number of “threads” in the body - distinguishes the following types from the assortment:

• Radiators with one heating element - a “package” of one pipe and one set of plates.
• Batteries with two or more heating elements , the design of which includes a pressure manifold that distributes the coolant flow over several “packages”, and a return manifold that collects the “outgoing” coolant for subsequent transfer to the distribution system.

The first type of radiator is cheaper and more compact than the second type. However, the latter option will provide higher thermal power, explained by the larger area of ​​​​the heating elements (plates and pipes).

The third classification option - according to the wiring diagram - distinguishes the following types of batteries:

• Radiators with side connection . In this case, the battery connections are located on the side surface of the casing. Because of this, the buyer of the battery will have to install special fittings - corners that ensure the pairing of the horizontal heating element (pipe) and the vertical section of the fittings extending from the horizontal pressure or return branch of the wiring. However, if the distribution pipes are laid vertically, then corners are not needed.
• Radiators with bottom connection . In this case, the battery fittings are located in the lower part of the casing, on the bottom side, which makes it easier to connect the radiator to horizontal wiring, while at the same time making installation to a vertical riser difficult.

As a result, owners of heating systems with horizontal wiring are recommended to use batteries with a bottom connection, and owners of systems with vertical risers are recommended to use batteries with a side connection. Although the latter option can be adapted to horizontal wiring using a cheap fitting - an angle.

The fourth classification option - according to the method of attachment to the supporting surface - distinguishes the following types of radiators:

• Mounted batteries , the housing of which is attached to the wall using special brackets.
• Built-in batteries , the housing of which is “recessed” into the floor, resting on the floor slab at the bottom.

Moreover, it is the mounted radiators that are most widespread. After all, the installation of batteries “recessed” into the floor requires a lot of effort aimed at arranging a niche and hidden wiring.

Advantages and disadvantages of stainless steel radiators

When comparing the performance characteristics of steel batteries with devices made of other materials, heating radiators made of stainless steel have advantages in a number of indicators:

• Due to the simplicity of the design, they have a long service life. High-quality heating devices are made of thick steel (1.2 - 1.5 millimeters), which has a positive effect on their strength;
• The presence of different options makes it much easier to install steel radiators yourself. On the website of well-known manufacturers there are always instructions that clearly and in detail explain how the device should be connected for different heating design schemes;
• The design of steel radiators makes them one of the worthy components of an apartment’s interior.

Steel plate radiators - general information

Steel plate radiators are commonly called “accordions”. The appearance of an accordion is created by plates strung on a coolant pipe.

A distinctive feature of such radiators is their high reliability. There are no connections in a plate radiator except for the coolant inlet and outlet. As a result, the radiator itself simply cannot leak; there is nowhere for the coolant to break through.

Thanks to the large number of plates and the direct movement of the coolant, the convector heats up to a high temperature. To protect against touches, the main frame of the radiator is covered with a decorative casing. Convection holes are made in the top cover of the casing.

Convectors have low thermal inertia, which means they can be controlled automatically, that is, thermostats can be installed in systems with plate radiators.

Technical characteristics of steel batteries

Battery specifications include:

• heat transfer;
• inertia;
• operating pressure.

Each type of heating structure has its own technical features. Heat transfer depends on several factors:

• sizes ;
• presence of a protective casing;
• functions ;
• masses.

The protective casing reduces heat transfer, and the presence of a convector increases it.

Inertia - the property of steel to quickly heat up and cool down, depending on the temperature of the carrier.

The weight of each radiator is determined by the model and dimensions. But, in comparison with their cast iron counterparts, steel batteries are much lighter.

The operating pressure that steel heating devices can withstand depends on the specific model and the wall thickness of the pipes and sections. Thus, panel batteries can withstand pressure up to 40 atmospheres , while tubular models will not withstand pressure above 13 atmospheres.

Connection options for heating elements

Connecting a plate battery.

Any factory-made plate heating element is equipped with a kit with a built-in valve insert. It, together with the thermostat, participates in the process of adjusting the temperature of the radiator. In addition, there are batteries with an integrated complex through which they are connected to the heating circuit pipes located under the floor or mounted in the wall.

Convectors in most cases can have either a side or bottom connection. In the case of the lateral connection method, the fittings of the heating element are brought out to the side of its casing. With horizontal heating wiring, the owner of the battery will have to buy a special fitting. It will help adapt a horizontally located device and a vertically rising section of reinforcement from a horizontal contour. Things are better if the heating circuit runs vertically through the room. Then the fitting is not needed.

With a bottom connection, the radiator pipes exit to the surface of the casing from below. This simplifies the connection of the heating element to a horizontal circuit, but complicates the installation process in the case of vertical wiring.

A steel plate heating radiator should only be connected to a system with forced coolant circulation. Otherwise, water will move at a low speed through the system, which will degrade the performance of the heating element.

It is not recommended to install steel plate convectors in a heating system with an open expansion tank. In this case, the coolant is regularly enriched with oxygen due to direct contact with air. As a result, the acidity of the coolant increases, which leads to corrosion of the inner surface of the radiator tubes. Their service life is reduced.

If water convectors are nevertheless installed in an open heating system, then the circuit must be equipped with an anti-diffusion barrier. It prevents oxygen from entering the heating circuit.

Features of installation of cast iron batteries

Like all heating radiators, cast iron heating radiators are mounted under the window, this is done to “block” the cold air coming from the window. The heating device must be installed at a distance of at least 5 cm from the floor and window sill, and the distance to the wall should not be less than 4 cm. This is done for ease of repair and maintenance of the device.

Important! In private wooden houses it is not recommended to install cast iron radiators on the walls. Mounts installed in wooden walls may simply not support the weight of the radiator. In such cases, it is recommended to use additional supporting legs of the stand, or use other types of heating radiators.

6-section radiator.

The heavy weight of cast iron heating devices requires the installation of powerful fasteners. For them, 4 holes 12-13 cm deep are drilled, into which fasteners are mounted using cement. After the cement has dried, the radiator itself is installed on the fasteners. Marking of drilling locations is carried out using a plywood or cardboard template, on which the radiator itself and its mounting locations are indicated.

Determination of thermal power of plate heating devices

The formula for determining the thermal power that a steel plate heating radiator can produce, and a real example of calculating this parameter, are given below. To calculate the power of the device, it is enough to know the heat loss coefficient of the heated room, the area of ​​the room and its total volume. The passport of any radiator indicates its calculated power at a hot water temperature in the system of 600C. The attached documentation also contains recommendations for the heated area for a specific radiator model.

The thermal output (power) of heating devices depends on the length of the body and the number of plates. The standard height of radiators is 200 mm, the number of plates varies. For example, heat transfer for a radiator with one tube and a body length of 600 mm will be equal to ≈ 347 W. When the length is increased to 3000 mm, the heat transfer will increase to 1730 W. But with the same body length (3000 mm) and an increase in pipes to 4, heat transfer there will already be 4179 W, and with a body length of 1000 mm, four tubes with coolant will give 1393 W of power. Therefore, which radiator is best to buy for a specific room is determined based on the following requirements:

1. To heat 1 m2 of a room with a ceiling height of 3 m, you need to spend 100 W;
2. For a room with an area of ​​16 m2, the radiator must have a thermal power of 1600 W, provided that the room has no more than one window, the room is not corner and the ceiling has a height of no more than 3 m. For other initial conditions, correction factors Kp are introduced:
3. For two windows Kp = 1.8 / 1600 x 1.8 = 2880 W;
4. For a corner room Kp = 1.8 / 2880 x 1.8 = 5184 W;
5. For a ceiling 2.65 meters high Kp = 2.65 / 3.0 = 0.88 / 5148 W x 0.88 = 4547 W;
6. For PVC windows Kp = 0.8 / 4547 W x 3637 W.

A standard metal-plastic window is 1400 mm wide, so to fully block cold air flows, a radiator of four sections 1400 mm long, with a power of 1950 W, is installed underneath it.

Power table

The heating radiator works like this:

1. Under pressure or gravity, the coolant moves through the battery tubes, heating them;
2. The tubes heat the plates welded to them, and together the structure heats the air between the radiator elements, which rises up to the ceiling of the room;
3. Cold air masses, under the pressure of warm air, fall down to the radiator, where they heat up;
4. Then the cycle repeats.

That is, in any radiators, the room is heated with coolant due to air convection.

Plate radiators have one distinctive feature: due to the small diameter of the coil, an insufficient amount of coolant passes through them per unit time to heat the room, so it is necessary either to keep the temperature in the boiler constantly high, or to install radiators with a large number of plates (sections).

High power radiators

To increase the efficiency of a plate heating battery, a metal corrugation is placed on its body, which at the same time serves as a protective casing. The corrugated surface increases the heat transfer area, which leads to an increase in the volume of warm air.

In older models of plate radiators, convection (movement) of air occurred naturally - due to the movement of warm and cold air flows. New models have built-in electric fans, and therefore you only need to increase the coolant temperature without increasing the radiator area in order to achieve the maximum possible heat transfer from the device. That is, in modern models artificial (forced) convection occurs.

Plate radiator with fan

Today, manufacturers offer to buy radiators made from the following materials and different designs:

1. The steel radiator has both tubes and steel plates. Although its strength is high, heat transfer is characterized by inertia;
2. The copper radiator has increased power and heat transfer. All this is accompanied by the high cost of the device, but if you decide to buy it, choose a copper coil and steel plates: it will be cheaper and will not affect the quality and durability of the radiator;
3. An aluminum radiator is the cheapest model with minimal heat transfer inertia, but it cools down as quickly as it heats up. The body is not as durable as the first two models, and the metal itself is susceptible to corrosion due to poor-quality coolant. Therefore, it is better not to install such devices in central heating.

Radiators made of different alloys

History of cast iron radiators

Franz Karlovich San Galli - inventor of the cast iron battery

The first cast iron battery was cast in 1855 in St. Petersburg at the factory of the Russian industrialist and entrepreneur of Prussian-German origin, Franz Karlovich San Galli. His factory specialized in the production of heating and water supply equipment.

The new heating device was given the name “heizkörper”, which translated from German means “hot box”. It consisted of large diameter pipes and vertical disks.

The 150th anniversary of the invention of the cast iron battery was marked by a significant event. On October 19, 2005, a bronze monument to a heating radiator was installed on the wall of the entrance to the Samara State District Power Plant, which consisted of the heating device itself, a cat sitting on the windowsill, a window and curtains. The prototype of the battery was the still functioning old radiators in the building of the Samara Art Museum, which were made about 100 years ago (approximately 1914-1915).

The monument was made by sculptor from Samara Nikolai Kuklev. The author of the image itself is the residents of Samara, who, after the announcement of the competition, sent photographs of their pets sitting on the windowsills to the editors of local newspapers. Based on these photographs, the sculpture was created. Many Russian and foreign publications wrote about the opening of the monument, including NBC, BBC and others.

Procedure for calculating thermal power

Knowing the thermal power of one section will allow you to find out the required number, but how to calculate this parameter.

This article will look at several options on how to make the necessary calculations depending on different variables:

Power calculation by area

It is based on sanitary standards, according to which 1 kilowatt of thermal energy (100 watts per m²) should be available per 10 “squares” of space. When making calculations, it is necessary to take into account the correction factor corresponding to a certain region of Russia. For example, for Yakutia and Chukotka it is 2, for the Far East it is 1.6, and for the southern regions and republics it ranges from 0.7 to 0.9 (about

Connecting radiators

1. As is already known, before sale, a plate radiator is equipped with a tap and a valve insert with a thermostat for automatically adjusting the temperature of the coolant and air in the room;
2. Some models are equipped with mechanisms for connecting the radiator to the heating circuit under the floor or built into the walls of the room;
3. The main radiator connection diagrams are side or bottom: With side connection, the connections of the radiator fitting are on the sides, which does not interfere with connecting them to a vertical riser. With a horizontal connection, the radiator is connected through a fitting.
4. With a bottom connection, the radiator fittings are brought out from below, so a horizontal connection does not pose a problem, but for a vertical circuit, the radiator is connected through fittings.

Bottom radiator connection

Lateral radiator connection

Practical and organizational implications

The principle of operation of plate devices is the same as that of water ones - they increase and maintain the temperature in the room due to the flow of warm air.

1. The reliability and strength of steel radiators is much higher than that of devices made of other alloys and metals, therefore they are recommended for use in a central heating system.
2. Copper radiators are not destroyed by corrosion, but it is better not to install them in high-pressure systems. Another drawback is the high price.
3. Aluminum radiators are the cheapest of all, have excellent heat dissipation, but have a mechanically weak body, which also quickly corrodes in an acidic environment.

Since the connection of plate heating devices is carried out through the lower or side fittings, they can be mounted directly on the floor, built into the floor surface or hung on the wall of the room. For each individual case, you can choose your own design and technical equipment of the device.

Certain types of cast iron radiators

In the Soviet Union, quite a few enterprises were engaged in the production of cast iron batteries. It is enough to recall only some of the main models NM-140, NM-150, Minsk-110, R-90, RKSh. Most of them have already been discontinued, with the exception of one proven classic variety, the MS-140. New developments of domestic cast iron heating radiators are characterized by greater aesthetics. For example, the Ms-110 model from the manufacturer Santhlit has a depth of only 11 cm, which allows you to easily install it under a narrow plastic window sill.

Cheboksary World Cup products can have 1, 2 or 3 channels. Thanks to the flat outer side, greater aesthetics and ease of cleaning are achieved. Minsk two-channel products are also distinguished by their external beauty: in total, about 10 models are produced. As for imported cast iron sectional batteries, they are characterized by the presence of a double-sided smooth surface: due to this, a higher heat transfer coefficient is achieved. Among the inexpensive samples, it is worth noting the Chinese manufacturer Konner and its models “Hit”, “Modern” and “Fort”.

More expensive, but also higher quality products are represented by the Czech company Viadrus, the Turkish company DemirDöküm and the Spanish concern Roca. European models are characterized by special grace and the use of artistic casting. Moreover, the price for such patterned heating devices is an order of magnitude higher than steel ones.

As a conclusion, we can say that it is too early to write off cast iron radiators. This is confirmed by the fact that leading European manufacturers continue to produce them. Despite their heavy weight and some slowness in heating, cast iron batteries have no equal in terms of accumulation and retention of heat.

What parameters should you use to choose radiators for an apartment?

Now, knowing the weak points of central heating, you can already imagine what requirements good batteries must meet. Let's list them.

1. For radiators, the pressure declared by the manufacturer must exceed the pressure (both the working pressure and one and a half times the test pressure) in the heating system. Let's look at the numbers as an example. In five-story buildings with an old layout, this parameter is no more than 5 - 8 atmospheres. Modern multi-storey buildings are heated under pressure of up to 12 - 15 atmospheres.

2. Separately, we note the ability to resist water hammer. Because when living in an apartment, it is difficult to protect yourself from pressure surges in the heating; it is better to prevent trouble in advance. By the way, if you often hear humming and clicking noises from your batteries, contact your utility service. The pressure seems to be playing tricks in the system.

3. The quality of water in the domestic heating system is unimportant, so the batteries must withstand its “chemical attack” with honor without collapsing. It is necessary to use radiators with a special coating on the inside or chemically neutral material for the walls

And their thickness must be such that particles of sand and small pebbles do not rub it, acting like emery.

4. When deciding which radiators are best for an apartment, let’s not forget about their main function - to heat. That is, it is preferable to choose devices that have greater heat transfer.

5. Let’s not ignore the design of radiators - few people are satisfied with the ugly, poorly shaped cast-iron monsters that stood everywhere in Soviet times. I would like the radiators to harmoniously complement the decoration of the rooms - today this is quite possible

6. The last parameter is the duration of service. No comments are needed here. The less often you have to bother with installing these bulky and rather expensive devices, the more profitable it is for the owners.

What threats does centralized heating pose?

On the one hand, supplying heat from outside is more convenient than autonomous heating - you don’t have to bother with installing the boiler and setting it up. Autumn will come, and hot water will happily run through your radiators, warming your apartment.

But not everything is so smooth in the centralized heating system:

• Water that has traveled a long way contains many chemically active impurities that can cause corrosion of pipes and radiators.
• And small particles of sludge, which inevitably fall into the coolant, scratch the batteries from the inside, wiping them to holes after a few years.
• And the water temperature is not always stable - sometimes the batteries are at room temperature, or sometimes it’s impossible to touch them.
• And the most important danger is a sudden huge surge in pressure in the heating system, the so-called water hammer. It happens, for example, for the reason that the mechanic closed the tap of the pumping station too abruptly.

How to turn a radiator into a shelf

www.shelterness.com

The radiator can be made a functional device, and not be content with it only as a heat source. If you place a thin slab of marble, stone or quartz on top of it, you will get a beautiful shelf.

This option is best used in warm months when the radiator is not filled with water and does not heat up. In cold months, completely remove the stove from the radiator and the heating device is back in action. Or remove decorative elements from the shelf, if any, and leave it for drying gloves and socks in the winter. You can also install a year-round shelf, but you need to secure it a couple of centimeters above the radiator.
