How to correctly calculate the required number of sections for a cast iron radiator MS-140-500 according to their characteristics

Innovative technologies and the use of the latest materials have radically changed the approach to home heating in winter. But along with modern equipment, designs that have served humanity for many years still remain relevant. We are talking about a heating radiator made of cast iron. Let's look at what the MC 140 500 is, a cast iron radiator whose characteristics have changed little over many years of operation.

A little history

Let's start with an interesting fact. The fact is that one of the first cast-iron radiators still successfully heats one of the halls of the Imperial Court Chapel in St. Petersburg. It was made in 1857 in the workshop of Franz Karlovich San Galli.

Of course, the device was restored over a period of more than a century and a half. But the very fact that it still works great says a lot. And, of course, the design features were not changed. They are the same as the inventor came up with them.

San Galli developed its “hot box” for 4 years. The result was a horizontal structure made of a thick cast-iron pipe, densely covered with flat vertical disks. The design consisted of several levels. And the size of cast iron radiators of that time was impressive.

The inventor arrived in Russia from Poland. Having learned iron casting skills at the St. Petersburg Machine-Building Plant, he decided to open his own workshop. But sinks, fireplaces and beds were of little interest to residents on the Neva. And in order not to end up on the street, the Polish German had to come up with something original.

At that time, a heating system using hot water had already been developed. But it used steel pipes in the form of a coil, which the insidious heat carrier dealt with in a short time. A material was needed that could resist water aggression for a long time. And it became cast iron.

Long-lasting heating batteries quickly gained popularity in the cold northern capital. Orders poured in, and the developer set up widespread production. Franz Karlovich did not make a secret of the discovery and cordially shared the manufacturing technology with everyone.

Europe immediately paid attention to the new product. And specialists from neighboring northern countries flocked to the inventor. It must be said that they not only successfully applied the innovation in their homeland, but also improved it. As early as 1872, Nelson Bundy adopted a vertical design that is still reflected in modern radiators today.

And in 1895, a well-known American company launched the production of the first cast billets. The power of one section of a cast-iron radiator compared to a steel pipe was so great that batteries of the required size were assembled from individual elements. American Radiators was also the first to use cast iron construction for steam heating. Because the material turned out to be super strong and could easily withstand high pressure.

Advantages and disadvantages of cast iron structures

It is believed that cast iron began to be smelted in China as early as the fifth century BC. The properties of the material turned out to be so unique that it has found wide application in all spheres of life. And in order to take a place in heating our homes, cast iron had to wait several thousand years. The corresponding technologies have not yet appeared.

Advantages

The advantages of a cast iron heating radiator are more than enough:

• The material is highly durable. Manufacturers provide a guarantee for their products for a period of 25 to 50 years. But it is often positioned that a cast iron battery can last at least a century.

• The radiator walls can withstand very high pressure - up to 12 units.
• Coolant heated to +130 °C can be used.
• The power of the cast iron radiator section is higher than that of its steel counterparts.
• Cast iron has very good rust resistance. This parameter can be explained by one circumstance. Rust is still growing in the structure. But it is considered “dry”. This layer further protects the material from the effects of normal corrosion.
• Cast iron is not afraid of dirt inside the structure. And wide channels cannot be clogged with any debris.
• The heat capacity of cast iron is high enough to retain heat long after the hot water supply to the system is turned off. After an hour, the battery will still retain 30% of the original heat. Steel can only hold 15%.
• In addition to the convective method of heating air, cast iron can radiate heat using the infrared method.
• Modern designs are collapsible. Therefore, you can select the required number of segments purely individually. And replacing a broken unit is much easier.

Increasing battery segments Source 1-teplodom.ru

• The dimensions of cast iron heating radiators produced today are quite compact. They easily fit into any room design.
• The cost of structures remains affordable for all segments of the population for many years.
• If you properly sort out and thoroughly rinse a previously used product, you can give a cast-iron battery a second life.

But some advantages can also play a negative role. For example, wide channels in a section require a lot of coolant to fill. True, this can hardly be called a serious drawback.

Disadvantages of a cast iron battery

Many people note that at the very beginning the boiler needs to work under serious load and without pauses. The high heat capacity of cast iron is to blame for this. And the system needs to overcome the inertia of heat. And this requires a lot of energy. But this begins to be compensated already at the stage of switching on the automation. Since the material retains heat longer, the pauses between turning on the boiler increase.

There are also very serious disadvantages. Despite its high hardness and strength, cast iron remains a brittle and non-plastic material. An accurate and strong blow is enough to split the product. It is also afraid of sudden temperature changes.

This is considered unlikely, but there were precedents. If you immediately run cold water into a battery heated to maximum, the walls of the product will crack. This can also happen if the coolant inside the battery freezes.

The second serious drawback is the significant mass. Even 1 section of the MC 140 radiator reaches 7.5 kg. Only two physically healthy men can lift a ten-segment battery. And if the coolant remains inside the system, then dismantling becomes very difficult.

Therefore, installation requires reinforced fastenings in the form of powerful hooks, or better yet, brackets. But they may also be powerless if the partition turns out to be flimsy. Therefore, before attaching the structure to the wall, the strength of the latter is checked.

Mounting brackets Source prom.st

There are often cases when, due to the impossibility of installation on a weak partition, cast iron radiators MS-140-500, the technical characteristics of which do not play a role in this case, have to be installed directly on the floor. In this case, special stands are used. But there are structures (of considerable length) in which legs are already provided on the outer elements.

Radiators are generally sold only with a primer outer coating. Therefore, fine-tuning to the aesthetic component is carried out independently. There are consumers for whom such an operation is considered difficult. In addition, it needs to be updated regularly. Preferably once every five years.

But even here manufacturers meet even such wishes halfway. And today’s market provides cast iron products with multi-layer painting. Naturally, their price is much higher. They also produce castings with antique decorative patterns. Such things are even considered exclusive.

Imported designs

Special mention should be made about Western-made cast iron radiators. They have one peculiarity. Heater sections are smelted much smaller than domestic ones. But they generate just as much heat as our larger cells.

European cast iron construction Source prom.st

The cast iron used for production is almost the same. But the technologies are strikingly different. Over the hill they require large investments. But the inner surface of the battery is smooth. Therefore, the coolant literally slides along it without experiencing resistance. This allows more water to pass through the radiator. And increased circulation means absorbing excess heat and increasing the power of the battery.

A striking example is Czech-made cast iron radiators. With compact dimensions, the power of one segment reaches 0.14 kW. But it only holds 0.8 liters of coolant. Even the best domestically produced samples with the same volume cannot generate more heat than 0.102 kW.

New generation radiators

Cast iron batteries of the new generation look much more attractive in appearance than old-style devices. They have a modern look and visually resemble radiators made of aluminum or steel. They have a flat front panel and a smooth surface. Some products already have factory enamel applied, other models are sold without it, and you will have to paint them yourself.

More recently, new generation cast iron batteries were imported only from Europe (Czech Republic, Italy) and China. Now they are already produced in Russia, Belarus and Ukraine.

Cast iron radiators CONNER HIT, Modern - European design

What are the advantages of modern radiators from European manufacturers? Their advantages include:

• high quality coating, they are marketed painted, while domestic models are only primed;
• smoother shape (both outside and inside);
• sections of smaller volume;
• higher level of heat transfer;
• less weight and dimensions.

Thus, imported models have more advantages than domestic ones, but they also cost significantly more.

Features of MS-140 brand batteries

Today, cast iron heaters with four, seven and ten sections are produced for sale in specialized stores. But since the design is collapsible, it is possible to assemble a radiator with any number of segments.

MS 140 Source prom.st

Let's look at the markings that MS-140-500 cast iron radiators have: technical characteristics of the last two digits and letter designations. The number 140 shows the depth of the segment in millimeters. And the number 500 (mm) indicates the distance between the axles. Another value found is 0.9. It indicates the allowed water pressure. And at the very end of the marking you can find a number indicating the number of cells in the battery. And most often the documents contain the following marking: MS-140-500-0.9-7.

There have been disputes over the letters MC for years. There are several decryption options. Someone is talking about cities. For example, that the first products were produced at one of the factories in Moscow. But there are only two acceptable versions. "Modified Standard" and "Multi-Sectional". The latter is more plausible.

In addition to sections with a depth of 140 mm, segments with smaller dimensions are also produced - 110 and 90 millimeters. There are also models with different heights between the axles. Just 300 mm. Such designs are more compact, but they have much less heat transfer.

You can also find such an article - MS 140 108 or 98. The last numbers indicate the gap between the nipples of the cells in millimeters.

MS-140-500 Source prom.st

The following companies produce cast iron batteries of the MC 140 series:

• Boiler and radiator plant in Nizhny Tagil (Russia).
• Heating equipment plant in Minsk (Belarus).
• Foundry and mechanical plant in Lugansk in Ukraine.
• Enterprises of OJSC Santekhlit, covering the Bryansk region of Russia.
• in Novosibirsk (Russia).

All enterprises operate in accordance with the regulations of their countries, and their products are certified ISO 9001:2008.

Technical standards for a cast iron heater

The performance of the entire heating system largely depends on the quality of the coolant. Water in the post-Soviet space leaves much to be desired. The concentration of aggressive chemical elements in it is so high that sometimes it can even corrode metals.

Therefore, consumers choose the cast iron radiator MC 140, the technical characteristics of which allow them to ignore this problem. And all because the battery material is not susceptible to chemical reagents. It is also not afraid of corrosion and is extremely resistant to abrasion.

MS-140-300 Source prom.st

The power of cast iron heating radiators and their technical characteristics are indicated in the table:

Radiator segments are cast from so-called gray cast iron. Moreover, there are a couple of channels for coolant inside. And for the latter they use water. But it can be heated up to +130 degrees Celsius. Almost turning into steam. And no design made of other materials can afford this. The maximum possible liquid temperature in stainless steel batteries rises only to +110 °C.

The MC 140 radiator segments are fastened to each other with nipples. They are also made from cast iron. But sometimes steel is used in accordance with GOST 1050. For sealing, rubber is used that can withstand heating up to +150 °C. The nipple hole is made with a G11/4 thread.

Among the additional technical characteristics of the cast iron heating radiator MC 140, it should be noted that the chemical activity of the metal is quite low. This allows you not to worry about the quality of the coolant. And normal water circulation cannot be prevented by hydraulic resistance. Because it's small.

Since, in addition to standard models, manufacturers also produce decorative (antique) ones, the height of the cast-iron battery differs somewhat, both up and down. Naturally, the size will affect the heat in the room. After all, the heating area of ​​the standard section is 0.19 m2. If the parameters are higher, then the heat transfer increases.

Main characteristics

MS-140M-500 is a cast iron radiator, the characteristics of which must be carefully studied before purchasing the product. This equipment is a convection-type device that has elliptical or round sections. The radiator releases approximately 25% of the heat flow transmitted by the coolant into the room. The remaining 75% is transmitted by convection.

On sale today you can find sectional cast iron radiators, the construction depth of which is 90 and 140 mm. If we are talking about the MS-140M brand, then we can say about it that the distance between sections is 300 or 500 mm. One section has a heat transfer surface of 0.208 m2. One section holds 1.45 liters and weighs 6.7 kg.

MS-140M-500 - a cast iron radiator, the characteristics of which may be useful to you, is equipment whose specific metal consumption is 42 kg/kW. Experts are sometimes also interested in the linear heat density of the flow; it is 1.48 kW/m. One section has a power of 160 W. For Russia, such devices are traditional today. Their main advantage is their ability to be used in open systems.

Calculation of the power of a cast iron battery

There is a misconception that the greater the power of 1 section of a cast iron radiator, the better. In fact, it is necessary to take into account the comfort of staying in the room. After all, few people know that when air is heated, oxygen is burned from it.

This will lead to the fact that over time a person’s breathing will begin to become difficult. In addition, the atmosphere is constantly drying out. Losing normal humidity will also not lead to anything good. The mucous membranes will dry out and no longer retain harmful microbes.

Multi-section cast iron heaters Source simpalsmedia.com

Excessive heat will actually cause large temperature fluctuations in the room. Because you will have to ventilate it more often. And after the body warms up under the influence of excess heat, the effect of drafts on it can be detrimental.

Therefore, it is especially important to correctly calculate the required power of a cast iron radiator for each individual room. There are various ways to do this. Let's look at each of them, from simple to complex.

The simplest calculation

General recommendations state that for every square meter in a room there should be an average of 100 W of heat. Therefore, measure the length and width of the walls of the room. Then the indicators are multiplied. And the found size of the room is again multiplied by 100.

For example, the area of ​​the room turned out to be 12 m2. This means that 1200 W of heat is needed to heat it. If you plan to purchase a standard model MS-140-500, then you need to find out the power of one section. Its parameter is 160 W. Now it remains to find out how many segments the battery should have. To do this, divide 1200 by 160. And the resulting result is always rounded up. And since the final figure is 7.5, for such a room you need to purchase a radiator with eight segments.

Battery with eight sections Source cast-radiators.ru

More accurate calculations

But it is better to look not for the area of ​​the room, but for its volume. Therefore, you need to multiply three parameters - length, width and height. Since standard ceilings in apartments are 2.5 meters, we get a room volume of 30 cubic meters.

Next you need to know a special coefficient depending on the type of structure:

• for a brick building – 0.034 kW/m;
• in panel houses - 0.041 kW/m.

The volume is multiplied by a coefficient. And if the room is located in a panel high-rise building, then 1.23 kW will be needed to warm it up. Dividing by the power of the standard battery section and rounding up, we get a radiator with eight segments. In a brick house you will need a battery with only six sections.

Difficult, but the most accurate way

In this case, many factors must be taken into account:

• square;
• volume;
• ceiling height;
• presence and number of windows;
• location of the room relative to the building;
• way to connect a battery to a heating system.

First you need to find how much heat is needed to heat the room. It is best to use the more accurate previous method. Next, the final figure is adjusted according to all the conditions in which the premises are located.

Corner apartment in the house Source repair161.ru

And each has its own coefficient:

• corner room - 1.8;
• the presence of a large window or a pair of small ones – 1.8;
• presence of double glazing – 0.8;
• bottom battery connection – 1.1;
• For the ceiling coefficient, you need to divide the height of the room by three.

Let's assume that the dimensions of the room are the same, and the listed factors are all present. The ceiling coefficient for a room 2.5 meters high will be 0.8. If the house is panel, then the required heat when adjusted will be within 2.8 kW. To meet this need, you will need a battery with eighteen segments. You can place two radiators in the room, each with 9 sections. For a brick house you will need 14 segments.

We remind you that for the calculations we took a room with an area of ​​12 m2 with ceilings of 2.5 meters. The room has a corner location and has two standard windows equipped with European double-glazed windows. And the power of one segment was taken from the MS-140-500 battery.

Indicators influencing the calculation of the number of sections

When choosing a radiator for a particular room, you need to take into account technical features. For example, the calculation will be different for a corner and non-corner room, for a room with different ceiling heights and different window sizes, etc. The most important parameters that are taken into account when determining the required radiator power are:

• the area of ​​your premises;
• floor;
• ceiling height (above or below three meters);
• location (corner or non-corner room, room in a private house);.
• will the radiator be the main heating device;
• There is a fireplace and air conditioning in the room.

There are other important features that need to be taken into account. How many windows are there in the room? What size are they, and what kind of windows are they (wooden; double-glazed windows for 1, 2 or 3 glasses)? Was additional insulation of the walls done and what kind of insulation (internal, external)? In a private house, what matters is the presence of an attic and how insulated it is - and so on.

Cast iron radiators Conner (China)

According to SNIP, 41 W of thermal energy is required per 1 cubic meter of space. You can take into account not the volume, but the area of ​​the room. For a 10 sq.m standard room with one door and one window, one door and an outer wall, the following heat output of the radiator will be required:

• 1 kW for a room with one window and an outer wall;
• 1.2 kW if it has one window and two external walls (corner room);
• 1.3 kW for corner rooms with two windows.

In reality, one kilowatt of thermal energy heats:

• In houses made of brick with a wall thickness of one and a half to two bricks, or made of timber and log houses (window and door area up to 15%; insulation of walls, roof and attic) - 20-25 sq. m
• In corner rooms with walls made of timber or brick of at least one brick (area of ​​windows and doors up to 25%; insulation) - 14-18 sq. m
• In the premises of panel houses with internal cladding and a thermally insulated roof (as well as in the rooms of an insulated dacha) - 8-12 sq. m
• In a “living trailer” (wooden or panel house with minimal insulation) – 5-7 sq. m.

Connection options for cast iron batteries

There are four ways to connect radiators to the heating system:

1. Diagonal. Suitable for batteries with a large number of sections. The upper fitting is connected to the supply on one side of the radiator, and the lower one is mounted on the return on the other. The sequential connection principle implies that the coolant will circulate only due to the pressure in the system. And to remove airiness, Mayevsky taps are installed.
2. Lower. Used when the system is located below floor level. The most aesthetic method, since communications are not visually visible.
3. One-sided. Both supply and return are connected from the side, on one side of the battery. This method guarantees very high heat transfer. Even if the pipe connections are confused. In this case, the power may decrease by only 10%.
4. Parallel. In this case, the supply and return pipes are connected by a separate jumper, with a shut-off valve installed between them. The battery is connected to the pipes on one side. If you install shut-off valves at each inlet, the radiator can be easily dismantled for repairs, and the system continues to operate.

When connecting by any of the methods, it is necessary to provide a place for carrying out maintenance work. This will allow servicing the system without dismantling and temporary shutdowns.

terms of Use

The radiator is used in water/steam heating systems with any type of boiler, in which the coolant is ordinary water, without specific requirements for its quality.

Installation should only be carried out in a heating network that is designed, installed and operated in accordance with regulatory documentation adopted by government industry organizations.

For Russia, such a regulatory act is the rules SP 60.13330.2012 or 73.13330.2012.

Features of installation of cast iron structures

There are certain rules that will ensure better system performance if they are strictly followed. It is also necessary to adhere to the established sequence of work. By following the recommendations of specialists, you can increase the guarantee that your heating equipment will last for many years.

Help for selecting battery sizes

Experts say that to provide the most effective protection from the cold, the radiator should occupy at least 70% of the width of the window opening. In this case, you can avoid cold areas on the sides of the battery. And this will eliminate condensation on the window and the appearance of dampness.

Rules for the location of the radiator, relative to the floor, walls and window sill:

• It is necessary to mark the middle of the window opening with extreme accuracy. From this point, segments are laid to the right and left. They are taken knowing the size of the cast iron battery in order to accurately position the fastening elements.
• To reduce the lower cold zone, the radiator should be located from the floor at a distance of 8 to 14 cm.
• The convention will not be violated if you leave 10 to 12 cm from the radiator to the windowsill.
• The heater's thermal output will increase if it is placed 3-5 cm from the wall.

Mounting the battery on the wall Source ytimg.com
Knowing these parameters, it will be much easier to choose a cast-iron structure of the optimal size. But you should know that literally every manufacturer has its own recommendations for installing products. Therefore, it is a good idea to read the instructions supplied with the radiator.

Preparatory work

Before installing the device, you must carefully examine the walls. The method of fastening them will depend on what material they are made of. Since it is not possible to properly strengthen a weak wall, you will have to think about a system of stands on the floor in order to install a heavy radiator on them.

This step will be necessary if the partition is wooden and made of plasterboard. If the surface is monolithic, then you just need to prepare it. If possible, it is leveled and a heat-reflecting shield is glued on top. This will increase the heating power.

The future location of the radiator should be with a minimum slope towards the return line. This will ensure free and proper circulation of coolant. If you mix up the slope, air pockets will form, which will not allow hot water to move through the system.

Controlling the correct slope Source remont-system.ru

Installation of brackets

Correct installation of fasteners is the key to good performance. It would be a good idea to try on the radiator in place before installing the fasteners. This will help you maintain the correct slope. And since the weight of the structure is considerable, you need to prepare a layout. A lightweight cardboard imitation will allow you to accurately mark the locations for fastenings.

Sequential steps for installing brackets:

• Using a radiator model, points on the wall are marked.
• Holes of the required diameter are drilled.
• Plastic dowels or wooden plugs are installed.
• Brackets are driven into the prepared holes.
• The fastenings are fixed with concrete mortar.
• After complete hardening, the strength must be checked.

To install a cast iron radiator, four brackets are enough. Two are located at the top of the structure and two at the bottom. When building up sections, fasteners are added.

Step-by-step installation steps

To connect the battery to the heating system, you must do the following:

• Hang the radiator on the brackets.
• The upper battery collector must be equipped with an adapter with an installed air vent.
• Free collectors are provided with plugs. If they do not fit in diameter, then they are installed through adapters.
• Shut-off valves are installed at the inlet and outlet of the battery. It will help quickly eliminate coolant leaks in the event of an accident. And it will provide convenient repairs without dismantling the system.
• Adjustable fittings in the form of manual or automatic thermostats are installed at the request of the homeowner.
• By choosing one of four connection schemes, inlet and outlet pipes are connected to the battery. The connection can be threaded, crimped or welded.
• After this, the radiator is pressurized.

To avoid water hammer, it is necessary to fill the system with coolant as slowly as possible, gradually opening the taps to full speed. At this stage, it is better not to remove the protective film from the product. This operation is left for later, when painting of the battery is completed.

Decoration

The easiest way to complete the heating system is to paint the radiator. To do this, select a durable palette of colors that will look harmonious in the overall interior. If desired, you can apply patterns or ornaments to the surface.

For those who think that cast iron radiators look too barracks-like, it is recommended to hide them behind decorative screens. Just don't use a blind shield. Otherwise, the circulation of heated air will be disrupted. It is best to install a wooden grate. Or use a screen with many holes.

I still disagree a little, of course this radiator is good, but nowadays there are other radiators of a more modern type that are lighter, more comfortable and visually pleasing. In addition, the heat transfer of cast iron is lower than that of aluminum; by the way, for me, the best ones are bimetallic.

Andrey, there is nothing better than cast iron. Excellent price/quality ratio, and the most important thing is durability, painted and like new. About aluminum ones, I can say that not everything is so good, yes, they are light and beautiful, but with our water quality, the radiator is very susceptible to corrosion and heat transfer is significantly reduced. And bimetallic ones are very expensive. So the best choice is cast iron. Just because they are heavy, it’s not a big deal if you hang them up and forget them, and then when they start leaking you can turn them into metal.

I agree that cast iron radiators are a thing of the past, and no one has installed them for a long time, they are heavy and do not look aesthetically pleasing, although they keep the heat longer.

Answer

User reviews and recommendations

Aluminum or bimetallic batteries for home heating cope with their functions much more efficiently. But their service life is not long. And many users do not want to spend large sums for a short period of time. Therefore, cast iron radiators with good power of 1 section still remain relevant.

People are mistaken when they talk about the negative side of using large amounts of coolant. The opinion that this will cause severe heat loss is erroneous. In fact, a larger mass of hot water will provide even better heat transfer.

This factor remains decisive when the heating system boiler turns off for any reason. A large amount of coolant in the battery allows it to remain hot for a long time. Whereas other systems immediately begin to cool down. And after a short time the radiators in them become cold.

Pressure testing of a cast iron battery Source 1c-bitrix-cdn.ru

Experience shows that the material of the battery also contributes to heat retention. Cast iron in this case is at the highest altitude. Leaks are very rare in such products. And if they happen, then there is a high probability that, due to “dry” rust, the microcracks themselves will become slagged.

Users recommend not leaving any window without batteries. It is in this area that the largest heat leaks from the room occur. A radiator under the window sill compensates for heat loss. It will also be a guarantee that no matter what the winter, your home will remain warm.

Briefly about the main thing

When installing a heating system at home, many owners think about saving money. But at the same time, none of them wants to stay in a cold apartment when the frost outside the window increases. Therefore, the choice of heating radiator is of utmost importance.

A large number of people whose home heating system uses hot water focus on the classic cast iron radiator MS-140-500 (or 300). Over many years of operation in different conditions, the design has proven itself only on the positive side.

Due to its good flow capacity, the heater segment has excellent thermal output. And the material has special properties that allow it to retain and release heat for a long time, when the boiler no longer heats the water. At the same time, the design is not at all afraid of corrosion.

Despite its excellent advantages over radiators made from other materials, a cast iron battery has one significant disadvantage. Its mass is very large. Therefore, installation is only possible on a sufficiently strong wall. But if there is none, then you can always use special stands or legs and install the radiator directly on the floor. System performance will not be affected by this.

Installation Rules

The number of sections has been calculated, the radiators have been purchased, and all that remains is to install them. There are two options here - seek help from specialists or do everything yourself. If financial possibilities are limited, then we carry out the installation process ourselves.

For fastening cast iron radiators, the following are used:

• Pin brackets - when the wall is made of gypsum concrete blocks or bricks.
• Corner brackets - when the wall is wooden.

1 sectional radiator requires 3 brackets, which are secured using a drill and dowels. The next step is to remove the film from the cast iron structure and connect the supplied pipes to the battery so as not to damage the threads and avoid water leakage from the heating system. The distance from the floor to the bottom edge of the radiator is at least 10 centimeters, and between the wall and sections - up to 5 centimeters.

Radiators can be connected either in series or in parallel. Regardless of the method chosen, you first need to turn off the coolant supply through your riser. To do this, you will have to contact a service organization - a housing office or a housing department. After the riser is closed, you need to drain the remaining coolant from the old radiators and pipes. After dismantling the old heating devices, you can connect new cast iron sections.

Assortment in the store

You should work carefully so as not to strip the thread, otherwise you won't have any problems. Having opened the Mayevsky tap, it is necessary to release the air accumulated in the heating system and supply coolant by opening the riser

Installation of radiators with parallel connection is carried out similarly to the first method and differs only in that if there are shut-off valves, you will not have to block the central riser. If desired, modern temperature sensors and thermostats are inserted into the radiators, which allow you to regulate the heating temperature of the radiators.
