Displacement of a cast-iron battery. Important technical characteristics and weight of cast iron radiators
Sectional cast iron radiators began to be produced more than a hundred years ago. They were first used in systems steam heating and then in central water heating systems. Classic Soviet-made cast-iron radiators MS-140 are installed in many old Russian houses.
Advantage cast iron radiators in their high reliability and long service life (more than fifty years). The radiator consists of sections made of high quality cast iron, which are connected by ductile iron nipples. The large diameter of the flow section makes cast iron radiators unpretentious in terms of the quality of the coolant and allows the use of polluted water typical for central heating systems in Russia, for the same reason they have a low hydraulic resistance. The thick walls and chemical properties of cast iron make the radiators resistant to corrosion, which is important in the summer, when the water from the heating system is drained and the radiator is left to rust "dry". Cast iron radiators are the cheapest of their counterparts, with the exception of highly artistic products with complex casting. Their price is much higher.
The disadvantages of cast iron radiators are their large mass. For this reason, installation is complicated and transportation costs increase. Cast iron radiators have a large thermal inertia (they heat up for a long time and cool down for a long time) , therefore, they cannot be used in heating systems with automatic temperature control, due to the long response.
Reliable and time-tested heating appliances. The design of MS 140 is ideal for Russian heating networks. They are completely insensitive to the quality of water used as a heat carrier. The most affordable heating radiators.

Cast iron radiator dimensions
Cast iron batteries, which have celebrated their centenary, continue to bring heat to residential buildings and are in no hurry to give way to aluminum counterparts and compact convectors. Cast iron has many undeniable advantages: resistance to corrosion, thermal efficiency, durability. Modern appliances have an attractive design, and the range of retro-style models looks simply luxurious. With all their advantages, they have one drawback - the weight of a cast-iron radiator is several tens of kilograms.
How much does a cast iron battery weigh
Knowing and taking into account the weight of the heating battery is especially important in cases where the devices are installed on thin walls and partitions made of fragile materials. If the load is higher than normal, you will have to abandon the wall mount and fix the radiator to the floor.
The weight of a cast-iron radiator section without coolant is from 7.1 to 7.5 kilograms - the exact values \u200b\u200bdepend on the height of the product and other features of the model. Among the new developments there are lightweight modifications with a section weight of 5.7 kg. Standard batteries consist of 4-10 sectional elements, but there are also "giants" that include 20 or more links.
Knowing how much a section of a cast-iron radiator weighs, it is easy to calculate the mass of a battery consisting of several tanks. For example, a device of 7 sections will weigh 48-52.5 kg, and a ten-section device will have a load of 70-75 kg. In order to facilitate installation, several devices from 5–7 sections are chosen, rather than bulky multi-section structures. If necessary, prefabricated devices are upgraded by adding or reducing the number of elements.
When calculating the total mass of the heater, it should be borne in mind that the volume of a cast-iron radiator section averages about one and a half liters of liquid. In new economical models, there are indicators from 1 liter, and in old-style radiators, the amount of coolant can reach 1.7 liters. Naturally, the weight of the device after starting the heating system will increase.
Technical characteristics of cast iron batteries
Other equally important specifications cast iron radiators. Their knowledge and ability to calculate desired parameters help to correctly determine the number of sections in the heat source.
Comparison of the characteristics of cast iron batteries and other types of devices |
Power is the main indicator of efficiency
Knowing the power of a cast-iron heating radiator, it is easy to calculate the number of devices. It is important to consider that in systems with central heating, where it is impossible to control the temperature of the coolant, an excess of heat sources is no less unpleasant than a lack. The result of an error is increased dryness of the air, an unpleasant smell of burnt dust, drafts from the need for frequent ventilation.
The thermal rated power of one section of the cast-iron radiator of the standard modification is 160 W. When calculating the dimensions of a heating unit, it is necessary to determine the value heat flow dwellings. This indicator depends on the wall material used for construction and the degree of thermal insulation of the building. In a panel house, the heat flow is 0.041 kW / m3, in a brick building - 0.034 kW / m3, and in the presence of high-quality thermal insulation - 0.02 kW / m3, regardless of what the walls are built from.
To calculate the number of links, a simple formula is used: the figure indicating the volume of the room is multiplied by the heat flow of the room, after which the resulting value is divided by the nominal heat flow of one section (0.160 kW). The result is rounded up to a whole number - this is the number of required elements. It is not necessary to combine them in one radiator - if there are several windows, it is better to install the device under each opening.
The heat transfer of cast iron radiators directly depends on the number of sections in the heater and their size. The dimensions of the battery are selected taking into account the area of \u200b\u200bthe room and the dimensions of the window opening. In order for the power declared by the manufacturer to “work”, the length of the battery must overlap the window by at least 70-75%, and the distance to the window sill should be from 8-12 cm.
Cast iron radiator dimensions
Manufacturers adhere to the generally accepted sizes of cast-iron heating radiators - this is a tribute to tradition and an important factor in ensuring the efficient operation and safety of equipment.
- The width of one section of the cast-iron "accordion" varies from 35 to 60 cm. Different values \u200b\u200bare found not only among competing manufacturers, but also in various model lines one manufacturer.
- The depth of typical products is: 92, 99 and 110 mm. In design modifications, other numbers are possible.
- The center distance in standard modifications is 35 and 50 cm, but there are other parameters.
- The height of the devices is always greater than the center distance and can be increased by the length of the legs, if we are talking about a floor model.
- The area of a cast-iron radiator section is on average 0.25 sq. meters.
Service life and other parameters
The service life of cast-iron heating radiators is estimated for decades. After installation is completed, you can not think about replacing batteries in the next 20-25 years. It is known that equipment cast more than 100 years ago is still working properly in pre-revolutionary buildings.
The working pressure of devices made of cast iron is 9 atmospheres, which allows them to be used in autonomous and central heating. Also, cast iron is not afraid of coolant drains in the summer season - it calmly waits heating period without losing their properties.
After studying the technical specifications and finding out how much a cast-iron heating radiator weighs, practical people trust system calculations and installation to specialists. It is always safer than trying to do an unfamiliar thing with your own hands.
It is unlikely that you have a dream to spend this winter in an ice apartment under ten blankets. Therefore, today we will talk about heating radiators, namely the cast-iron radiator MS-140.
We will review the characteristics, tell you how to choose the right number of sections and how to mount it all. But first things first.
Why cast iron
Cast iron radiators have a number of advantages, consider the main ones:
- High resistance to corrosion. This property is due to the fact that during operation the surface of the radiator is covered with “dry rust”, which prevents corrosion from developing. Also, cast iron is very wear-resistant; stones and various debris from heating pipes do not cause much harm to it;
- Good thermal inertia. The cast-iron heating radiator MC 140 retains 30% of the radiated heat even an hour after the boiler is turned off, while for steel radiators this figure is only 15%;
- Long service life. So for high-quality cast iron radiators, it can reach 100 years, although manufacturers talk about 10-30 years of confident operation;
- Large internal section of radiators. It is for this reason that cast-iron heating radiators MC 140 500 rarely require cleaning;
- Cast iron, due to its composition, under no circumstances can cause electrochemical corrosion. In other words, no conflicts with plastic (steel) pipes can arise.

But, knowing the advantages of devices and their characteristics, do not rush to run to the store. After all, before that you need to find out how many sections are needed for the heating to be really effective.
Section count
The number of sections directly depends on the configuration of the room. Of course, here the main parameter is the area, but there are other important factors, such as: zoning, floor, ceiling height, niche size, the presence of double-glazed windows, the number of windows.
Advice. For corner rooms, it is better to choose more powerful radiators and make several additional sections (1-2). This is explained by additional heat losses, which can affect the comfort of residents.
Consider the formula for calculating the required number of sections for a room with a ceiling height of not more than 3 meters and an area of 50 square meters:
Advice. If as a result of the calculation you received a fractional number, then it is better to round it up - provide a small margin of power.
Now that you know how many sections you need, you can proceed directly to the installation.
Mounting
The number of sections has been calculated, the radiators have been purchased, it remains to be installed. There are two options here - turn to specialists by spending money, or do it yourself. Let's consider the second option.
We select fasteners
The first step in the installation is choosing a mount for the radiator. In the photo you can see different types of mounts.
For example, pin and corner brackets are used for sectional radiators. The former are used to fix the battery on a brick or plaster wall, while the corner ones are used if the wall is wooden. It should also be remembered that for corner mounting it is necessary to stock up on self-tapping screws and dowels.
Types of fasteners. As you may have guessed, mounts No. 3 and No. 4 are applicable for our case.
Direct installation
At this stage, you need to choose a place to install the brackets. Remember that you need at least three brackets per radiator. After, using dowels and a drill, you need to fix the brackets.
The next step is to attach the radiator to the brackets.
Advice. You do not need to immediately peel off the protective film from the radiator, first install it on the brackets, and then, without fear of scratching the radiator, remove the film.
Carefully connect the supplied pipes to the radiator. Fasten carefully and carefully, but do not damage the threads, otherwise water will leak from the system. Before viewing, check out the installation video in our gallery.
During installation, it is important to observe certain distances. For example, the installation height above the floor should be approximately 10 centimeters. The distance between the wall and the battery should be from 2 to 5 cm.
Results
Cast iron appliances can be safely installed in your heating systems, of course, they are inferior in performance to new models, but their price is also low. In addition, they proved their suitability for a whole century, both in the USSR and in Europe. A big advantage is their long service life.
The radiator is an integral part of any apartment. This equipment provides home heating during the cold season. However, not every apartment can install one or another battery. After all, the requirements for this device directly depend on the area of \u200b\u200bthe room in which it is located. First of all, it concerns power. The quality of heating your home depends on this indicator. Therefore, today we will teach you how to correctly calculate the power of batteries.
We calculate the power of the heating radiator
Heating radiators provide heating to the apartment. Without this device, it is impossible to imagine any modern dwelling. It is thanks to him that we can spend cold winter evenings with comfort.
The power of a heating radiator is of great importance in heating a house. It is this device that gives most heat to the room. Without it, you would live in a cold and damp room.
Heating radiators can be made from different material. It can be aluminum, cast iron or steel. Also, such devices differ in their structure. They can be made from separate sections or be a panel.
When calculating the power, the material from which the radiator is made does not really matter. But the structure of such a device plays an important role in the calculation.
The radiator, consisting of sections, can be independently assembled to the required length. Thus, in this option, you will calculate the number of sections at which the radiator will have the required power.
How to calculate the required number of radiator sections:
- The first thing you need to know is the area of the room. To do this, you need to multiply the height of the room by the length of its two adjacent walls separately, and then add the two resulting numbers.
- You also need to find out the power of a single section of the radiator.
- Further, the area of \u200b\u200bthe room is multiplied by the power of a single section of the radiator and divided by 100.
As a result, you will learn a number that will equal the required number of radiator sections. It needs to be rounded up.
If you would like to purchase panel radiator. That calculation will be different. In this case, you will calculate the power of the device.
- First you need to calculate the volume of the room. To do this, you need to multiply the height of the room with the number obtained by multiplying the length of two adjacent walls.
- The resulting number is multiplied by 41. This figure is the required power to heat one cubic meter.
The resulting figure will be equal to the power of the radiator. It needs to be rounded up. With this, you can split the value into two heatsinks.
What is the power of one section of a cast-iron radiator
Cast iron radiators are the very first batteries. However, despite the newly-made models, such devices still occupy the first place in popularity.
Cast iron radiators MS-140-500 do not differ in their original design. However, such harmonicas have reliability and high efficiency.
At the moment, the appearance of the cast-iron radiator has reached a new level. You can see the models of different color. Moreover, some batteries of this type have a beautiful relief and even cast iron.
Heat dissipation from cast iron radiators is high. The power of a single section of such a device is 160 watts. However, it is believed that on average this figure can decrease to 140 watts. There is a table comparing different types of radiators. And in it, the cast-iron battery takes first place. Let's look at the advantages of such devices.
Advantages of cast iron radiators:
- Cast iron has a very high heat capacity. Due to this, radiators made of such material retain heat for a long time and give off heat in large quantities.
- Cast iron batteries, provided that they are welded correctly, calmly endure water hammer and temperature changes.
- The walls of such batteries are not susceptible to corrosion and wear. Therefore, absolutely any coolant is suitable for them.
If you have chosen this radiator, then you can be sure that you will not have any problems during its operation. However, many people are not satisfied with the appearance of such devices.
Average power of aluminum radiator section
Aluminum radiators are the most popular. This is due to their modern appearance and ease of maintenance. You can buy such models at a very affordable price in specialized stores.
In addition to the aluminum and cast iron radiator, there are steel batteries. The dimensions and weight of such devices are significantly inferior to models made of other materials. This is the advantage of steel radiators.
Aluminum radiators can withstand up to 15 atmospheres. Also they are not afraid high temperatures. That is why they are so loved by our population. The design of aluminum batteries is quite concise. Of course, such designs do not differ in special originality, but they are able to fit into any interior. The question of the power of a single section of such batteries is still on edge. It is impossible to answer this precisely, since different models can have from 180 to 200 watts. Sections of aluminum batteries are very easy to connect. Usually such services are provided by sellers in the store, but if necessary, you can assemble it yourself.
With all the advantages of aluminum radiators, they also have some disadvantages. In order not to regret what you did later, you need to familiarize yourself not only with the “for” reviews, but also with the “against” positions.
Disadvantages of aluminum convectors:
- Aluminum is the material most susceptible to corrosion. Moreover, during the rusting process, it can release gases. Therefore, such devices are most applicable in individual systems heating, where water quality is higher.
- If the sections are connected incorrectly, aluminum radiators may leak. And in this case, it will be impossible to fix them.
Aluminum radiators are very popular due to their high efficiency and low weight. However, they have serious drawbacks that must be taken into account.
The volume of water in one section of the cast-iron battery
Many are interested in the volume of water in one section. Since some people claim that the large size of such radiators indicates that one section contains more than three liters.
In fact, most of the volume of such a device is occupied by cast iron itself. It has a thick layer, and therefore the product seems so overall. Let's see how much water can be in one section of a cast iron battery.
How household water go into one section cast iron battery:
- The radiator model MC 140/500 holds 1.45 liters of water per section;
- The battery model MC 140/400 can fit 1.28 liters of water in one section;
- For the structures of the MS 140/300 model, 1.11 liters of water are needed.
As you can see, not as much water is placed in cast iron batteries as it might seem. Therefore, you can not worry about the economy of this resource.
