How much does 1 tooth of a cast iron battery weigh? Weight of cast iron battery section

Batteries have been made from cast iron for over 80 years. Based on this, a quality assessment can be made.

IN modern production heating batteries they use aluminum, steel, or both metals, but cast iron does not lose its relevance and is still in demand. Radiators made of cast iron have an optimal modification, low price and excellent technical parameters.

Advantages and disadvantages

Let's consider the main advantages:

Cast iron systems are durable and have a service life of 50 years, but with proper care they will last much longer. This is known to everyone and proven by time.
They can withstand pressure of 9–12 atmospheres, which reliably protects the batteries from water hammer. That is why they are installed in multi-storey buildings with central heating.
They can easily withstand temperatures from 100 to 130°C.
One section can produce thermal power up to 160 kW.
Cast iron radiators, unlike all others, are the most resistant to aggressive environments that cause corrosion.
They have wide channels, which also protects the batteries from water hammer and does not require frequent cleaning.
Infrared radiation, which only cast iron batteries possess, is capable of transferring heat to other objects. This allows the room to remain warm longer after heating.
Easily modified to allow installation of a battery required power. If necessary, it can be removed and enlarged, or reduced. For example: an old-style cast iron radiator usually consists of 8-10 parts. The larger the area that needs to be heated, the more prefabricated heating parts are needed. Yes, for the right thermal effect and comfort, in a room of 14 sq.m., you will need only 4 sections, which can be made ordinary and simple division sections.
Affordable price.

But the disadvantages of using cast iron heating radiators have also been noted:

Most main drawback– very heavy. Thus, the weight of one section without water reaches 7.5 kg. On average, from 6 to 10 ribs are installed, and this design weighs 50–58 kg.
Labor-intensive installation requiring special skills.
Low heat transfer due to high heat capacity. But at the same time, after a complete shutdown, this helps to retain heat for a longer time.

Decorative pattern

To calculate a heating system, it is necessary to take into account many different parameters. One of them is the heaviness of heating appliances. Let’s say you plan to install classic cast iron radiators consisting of 4–10 elements. In order to calculate the mass of the entire system, you need to know how much the cast iron battery weighs - this will ensure the reliability of its installation.

A little about cast iron radiators

The cast iron radiator is a classic of the genre. It has been installed for more than 100 years, and not a single modern novelty was never able to completely oust such a battery from the market. The popularity enjoyed by these radiators is determined by the characteristics of the cast iron itself.

Among the most important advantages it is necessary to note:

Corrosion resistance.
Long service life.
Undemanding to the quality of the coolant.
Excellent heat transfer.
Undemanding in operation.

A drop of tar in this barrel of ointment is a significant weight of the structure. One element cast iron battery weighs 7.5 kg. It’s easy to calculate that a standard radiator of 7 sections will weigh 50 kg. To ensure normal thermal regime One is not always enough in a room heating element. Because of this, you have to think about the reliability of fastening the system elements to the walls.

In addition, it should be remembered that cast iron is a brittle material. Therefore, when moving products made from it and installing them, special care should be taken to ensure that microcracks invisible to the eye do not appear in the cast iron from an accidental impact. During operation, when the pressure in the heating network increases, these cracks will begin to increase, which will inevitably lead to leaks.

Main characteristics

A standard heating device consists of 4–10 individual elements. The size of the battery is determined based on the thermal conditions that need to be provided in the room, as well as depending on architectural features the last one.

Classic version

Despite the large mass of the cast-iron heating device and the difficulties arising in connection with this, the weight of the battery is not a problem when installing it. The most important thing is to install it correctly. To ensure the correct installation of radiators, it is not enough to know only their mass. Other characteristics need to be taken into account:

Center distance. For standard models it can be 350 or 500 mm. Radiators with greater height, as a rule, are produced with a large distance between the axes.
Depth. Standard figures are 92, 99 and 110 mm.
Section width. There is a small spread here - 35–60 mm.
Section volume is the amount of coolant required to completely fill it. On average, the volume is 1–4 liters and depends on the size of the element.

Modern radiators are made of high-quality cast iron, which allowed manufacturers to ensure stability technical characteristics of its products. This also applies to the weight of one section - the most important parameter when calculating the load on bearing structures premises.

Important! Cast iron batteries are characterized by their modular design. This means that sections can be added or removed if necessary.

Varying the number of sections - the simplest way regulate the room temperature. As a rule, it is recommended to choose devices with a large number of sections relative to the calculated number. This will help solve the problem of strong temperature changes characteristic of the cold periods of the year in middle lane Russia.

Load calculation

Calculation of thermal power

Calculating the load on supporting structures, knowing the weight of one section of a cast iron battery, is quite simple. For example, let’s calculate how much a radiator consisting of 7 sections will weigh. The weight of one section without water is 7.5 kg. Multiplying this figure by the number of elements, we get the weight of an empty battery - 50 kg. This means that the brackets and fastenings used when installing the system must withstand such weight. This is theoretical. In practice, everything is a little more complicated.

After installation is completed, the system is filled with water, which will inevitably lead to an increase in weight and load on the fasteners. The weight gain may vary depending on the volume of the section. On average, the weight of the entire battery after filling the system with coolant will increase by 10–30 kg. Brackets selected based on 50 kg simply cannot cope with the increased load.

To the factors influencing Negative influence The fastening elements of the system also include movement caused by physical processes occurring during heating and cooling of the coolant.

Conclusion

In order for the heating system to serve for many years, parameters such as the weight and volume of the radiator section cannot be ignored. Only by correctly calculating the load on the fastening elements can you guarantee reliable installation, as well as uninterrupted operation of the entire heating network.

To calculate a heating system, you need to take into account many different parameters. One of them is the weight of heating appliances. For example, you need to install a classic cast iron radiator, which consists of 4-10 sections. To calculate the mass of the entire heating system, you must first make a calculation regarding one cast-iron battery, which will ensure its installation reliability.

Weight of one section of cast iron battery

About cast iron batteries

The cast iron radiator belongs to the classics of the genre. It has been used for more than 100 years and no one has yet been able to completely oust it from the market. modern model. Cast iron radiators are in demand due to the characteristics of the material itself.

Important advantages of cast iron are:

Corrosion resistance,
Long service life,
Undemanding to the quality of the coolant,
Excellent heat transfer,
Undemanding in use.

It can't all be that smooth, and two drawbacks are still there.

One lies in the mass. How much does a cast iron battery section weigh? Weight of 1 section cast iron radiator is approximately 7.5 kg. Thanks to simple conclusions, we can come to the conclusion that a standard 7-section battery will weigh 52.5 kg. To provide comfortable temperature In a room, one section of the heating element is usually not enough. Based on these circumstances, in order to ensure the reliability of the design, it is necessary to think through ways to attach the radiator elements to the wall. Let's do the calculation using an example. The Soviet model MC 140, which is still on the market, has a considerable mass - 7.12 kg. The volume of one section is 1.5 liters of water, the total weight is 8.62 kg. The thermal power is approximately 170 W. How many sections are needed to heat a room of 20 m2? If it is necessary to heat a room of 20 m2, then 12 sections will be required, then the mass will be 85.4 kg, plus water - 103.4 kg.
The second negative point of cast iron is its fragility. Therefore, in order to carry out the transfer of a product with a large mass and its fastening, it is necessary to carry out all manipulations with it as carefully as possible, preventing the slightest impacts in order to avoid microcracks invisible to the eye. Since during work with an inevitable increase in pressure in the heating network, the resulting cracks will begin to increase, which will end in radiator leaks.

Basic characteristics of a classic radiator

A standard cast iron battery consists of 4-10 separate sections. Its size depends on the choice of thermal conditions in the room and the architectural features of the house.

Despite the difficulties that arise when installing a heavy cast iron heating radiator, this is not considered the main problem. The main task is to perform correct installation batteries. To implement it, it is not enough to know only the mass of the product; it is necessary consider the following points:

Distance between axles. Standard models can have 350 or 500 mm. Batteries with a large height are characterized by proportional dimensions between the axes.
Depth. Standard sizes 92, 99, 110 mm.
Section width. The sizes are in a slightly larger range - 35 - 60 mm.
Section volume. This is the amount of coolant that is necessary to completely fill the radiator element. The volume depends on the size of the section. Average values range from 1 to 4 liters.

An important problem with installing a classic cast-iron battery is that it is only intended for wall mounting. At the same time, most modern houses made from porous materials, such as aerated concrete, foam concrete, as well as SIP panels with foam filling. These walls require special fastening complex design with multi-point fixation, which is unlikely to be to your liking.

Modern models of heating radiators

For wall mounting various manufacturers New models made of gray cast iron have been developed, their weight is much less than the old classic models. For example, let's describe the Czech heating radiator Viadrus STYL 500. How much does 1 section of this heating radiator weigh? And how much will the mass of the entire structure be?

The weight of 1 section is 3.8 kg, water holds 0.8 liters, so the mass of one radiator section with water will be 4.6 kg. With a heat flux of 140 W, to heat a room of 20 m2, 14 sections will be required, and the weight will be 64.4 kg with water. Thus, this indicator differs by 40% less than that of the classic MS 140 sample. If this value is divided into two parts (32 kg each), then we can conclude that installation on walls made of modern materials, including porous concrete, is quite possible without additional fasteners.

Even more lightweight design developed Russian manufacturers. Their heating devices are offered under the EXEMET brand, the MODERN model has the following weight characteristics:

One section from this manufacturer weighs 3.2 kg, heat output is 93 W. To heat a room of 20 m2 you will need 22 sections, then the total weight will be 70.4 kg. These parameters are not bad, especially considering that the company produces models with possible installation on the floor.

Vintage model

A few words about the vintage cast iron battery. Its weight exceeds the Soviet model, which can reach 14 kg. These heating devices look very much like the old ones that were installed in residences and estates back in the 19th century.

The EXEMET FIDELIA model weighs 12 kg, heat dissipation is 156 W, the total mass of the device for our example is simply monstrous - 154 kg. The complex issue of installation is irrelevant here, since the first and last sections equipped with legs to place the device on the floor.

So, in order to ensure uninterrupted service for the heating system, you cannot ignore such important indicators as the weight and volume of the battery section. Thanks to the correct calculation of the load on the fastening elements, you can count on reliable installation and long-term operation of the device.

Despite the fact that modern industry offers radiators steam heating from various materials(for example, aluminum and bimetallic radiators), many people prefer to install traditional cast iron batteries in their home. How justified is this? After all, cast iron radiators have a small heat transfer surface, and since this is a metal with a fairly low thermal conductivity, at least 8-12 sections will be needed to heat one room. The weight of a cast iron battery of 12 sections without water is 70-90 kilograms. Thus, after filling heating system water its total weight in big house can amount to several tons!

Advantages and disadvantages of cast iron radiators

However, all these shortcomings relate primarily to the Soviet-style, heavy, non-separable “accordion” radiators (MS-140M), familiar from childhood. Today, such batteries are found mainly in homes. old building. Of course, cast iron batteries are much heavier than aluminum and bimetallic ones.

12 section cast iron

For example, the weight of a section of a cast iron battery of the MS-140-300 brand is 5.7 kg, and the heavier MS-140-500 is 7.1 kg, which approximately corresponds to the weight of the sections of “Soviet” radiators (7.5 kg). But modern cast iron radiators can be assembled from the required number of sections, and design features and design allow you to take advantage of the advantages of cast iron batteries while reducing their inherent disadvantages. The advantages of cast iron radiators over batteries made of other materials are undeniable. In particular:

they are durable;
they are resistant to corrosion and can use process water;
they withstand better than radiators made from other materials high pressure, which means they can be used in multi-storey and high-rise buildings;
due to large diameter pipes and low hydraulic resistance. they can be used in systems with natural water circulation;
Thanks to the large volume of water in the sections and thick walls, they warm the room well and retain heat for a long time. Modern cast iron radiators are much lighter than their predecessors.

Choose the radiator correctly!

Heat capacity modern radiators does not always depend on its weight and dimensions. Thus, the weight of one section of a cast iron battery assembled from 2K60P radiators (Minsk) is 5.7 kilograms, however, due to the flat, rather than ribbed heat transfer surface and increased thermal power, it is enough to maintain heat in the room 8-10 sections. Assembled from 10 battery sections Czech production Termo is even lighter: the minimum section weight is from 4.45 kg (maximum - 6.8 kg).

These radiators are manufactured in various modifications(height - 560-673 mm, thermal power 146-290 W/section), which makes it easy to calculate required dimensions for any room. Könner radiators (China/Germany) are also light in weight: a section with a height of 365 mm weighs slightly more than three kilogram, while its heat output is 120 W. For comparison: the thermal power of the MS-140-500 radiator with a height of 588 mm and a weight of 7.1 kg is 160 W/section, and the weight of a section with a heat transfer of 120 W (radiator MS-140-300) is 5.7 kg with a height of 388 mm.

Cast iron radiator in retro style

In counting heating radiator you need to take into account not only how much a section of a cast-iron battery weighs and whether it is dismountable or non-dismountable, but also whether you can independently assemble it from sections, or whether the radiator is sold assembled. For example, the weight of one section of Könner radiators (China/Germany) is approximately 4 kg, however, these radiators are produced in complete form (4-12 sections).

Keep in mind that regardless of whether these are ready-made radiators or prefabricated radiators, the number of sections must be selected with some margin.

If the calculation shows that to maintain the required temperature regime In the room you need to install a battery of 10 sections, it is better to choose a 12-section radiator, and regulate the air temperature by lowering the temperature of the coolant water, shut-off valves, etc.

For a classic sectional radiator, the weight of 1 element is 7.5 kg, that is, standard design of 7 elements will weigh more than 50 kg.

Classic cast iron radiator

This raises two problems:

It is difficult to install a reliable wall mount if the walls are made of porous lightweight blocks or are frame structure- you will need to install the heating device on the floor;
It is necessary to carry the battery together and very carefully, since the impact causes microcracks to appear in the fragile cast iron, which expand under the influence of the heated coolant - over time, this provokes depressurization of the heating device.

Advantages of cast iron

If you don’t take into account how much a cast iron battery weighs, we can note a whole range of advantages of heating devices of this type , which include:

corrosion resistance;
resistance to chemically aggressive environments - the material is undemanding to the characteristics of the coolant;
durability;
high rates of thermal radiation - than more quantity sections, the higher the heat output of the heating device.

The appearance of standard cast iron batteries is simple and laconic, but today manufacturers also offer antique-style radiators. The advantages of such models include stylish and respectable appearance.

Various options radiators

Specifications

The power of a heating device is an indicator of its thermal efficiency. When calculating the heating system, the heating needs of the house are taken into account. It is important to know the power of 1 section of a cast iron radiator in order to determine the size of the batteries for each heated room. Incorrect calculations lead to the fact that the room will not warm up properly, or vice versa - you will have to ventilate it often, removing excess heat.

For an ordinary standard radiator made of cast iron, the power of 1 section is 170 W. Cast iron batteries can withstand heating above 100°C and operate successfully at an operating pressure of 9 atm. This allows the use of products of this type as part of central and autonomous heating networks.

Modern models

Manufacturers offer lightweight battery options made of gray cast iron. If the weight of 1 section of the Soviet MC140 radiator is 7.12 kg, then 1 section of the Czech-made Viadrus STYL 500 model weighs 3.8 kg, and its internal volume is 0.8 liters. This means that a Czech radiator of 10 sections filled with coolant will have a mass of (3.8 + 0.8) × 10 = 46 kg. This is 40% less than the mass of a filled MC 140 battery, consisting of a similar number of elements.

Lightweight cast iron heating appliances are also produced in Russia. MODERN batteries are produced under the EXEMET brand, 1 section of which weighs 3.3, and its internal volume is 0.6 liters. These tubular cast iron radiators are characterized by relatively low heat transfer, which requires an increase in the number of links. Heating devices are designed for floor installation.

Vintage cast iron radiators are becoming increasingly popular. These are floor models made using artistic casting technology. Due to the volumetric complex patterns, the weight of the cast iron radiator section is significantly increased, reaching 12 kilograms or more.

Vintage floor radiator made of cast iron

Life time

Houses built before the revolution still have cast iron radiators installed more than 100 years ago. Modern heating devices made from this material are also designed for decades of maintenance-free operation.

Durability is explained by the strength of cast iron, resistance to heat and pressure. Heating appliances made of cast iron do not rust during the period when the coolant is drained from the network and inner surface batteries come into contact with air.

Dimensions

The weight of a cast iron radiator section depends on its height, configuration and wall thickness.

Manufacturers offer models with different characteristics:

battery depth ranges from 70 to 140 mm in the standard version;
link width varies from 35 to 93 mm;
section volume – from 0.45 to 1.5 l depending on the dimensions;
height of the heating device in the standard version is 370-588 mm;
center distance – 350 or 500 mm.

Classic batteries: basic parameters

The Soviet MC140 battery with the following parameters is considered classic:

height 388/588 mm;
depth 140 mm;
width 93 mm;
the volume of one link with a height of 588 mm is 1.5 l;
the weight of one link with a height of 588 mm is 7.12 kg.

Knowing how much one radiator section weighs and its volume, you can calculate the mass of the MC140 heating device filled with coolant. total weight a filled section will weigh 8.62 kg, a battery of 10 links will weigh about 86 kg.

Wide selection of different battery styles

Basic calculations

When designing a heating system, it is necessary to calculate the weight of the radiator and required amount sections in batteries. Calculations are made based on the power of one section of the heating device (for a classic cast iron product this is 170 W) and the thermal calculation of the room.

To calculate the required number of sections and the final weight of a cast iron radiator, you should take into account the area and heat loss of the room, which depend on the characteristics of the materials from which the walls are built and the presence of insulation. You also need to pay attention to the number of windows and the type of window systems.

For panel house the optimal heat flow value is 0.041 kW/m 3 , for brick – 0.034 kW/m 3 , for buildings with insulated walls (regardless of the material from which they are built) – 0.02 kW/m 3 .

Considering the considerable weight of one section of a cast iron battery, the number of links in a standard radiator varies from 4 to 10. In a large room, it is more convenient to install two or three heating devices of 4-5 sections instead of installing one extremely heavy radiator with the number of links more than 10 .

Therefore

To choose the correct fastening principle, you need to find out how much a section of a cast iron battery filled with coolant weighs. For heating appliances made of cast iron, it is important to select the appropriate number of brackets for wall mounting. If the walls are made of porous blocks or the house is built from SIP panels, the number of fastening points is increased in order to more evenly distribute the load.

Correct calculation of radiators and reliable installation– guarantee of uninterrupted functioning of the heating system.
