How much does one section of the battery weigh

The advantages of cast iron are

Cast-iron batteries are the most profitable heating devices. If you do not take into account how much a cast iron battery rib weighs, then you can safely highlight a whole range of positive qualities of cast iron:

  • high heat output;
  • reliability;
  • durability;
  • durability;
  • durability;
  • the period of operation is more than 50 years.

The appearance of typical cast iron radiators is usually a bit complicated. But now there is a mass of heaters, made in the form of vintage products.

The advantage of these forms is the elegance and decency of their appearance.

Calculation of the required number of sections

After determining how much a cast-iron radiator weighs, you must calculate the required number of links in the radiator or the number of units to be installed in a single room. The figure, which denotes the volume of the room, multiplied by the value of the heat flux of the room, the resulting figure is divided by the heat flux of one section. Its value is 0.160 kW.

The figure obtained as a result of calculations need to be rounded to a whole this will be the number of required sections. There is no need to connect all the sections into one radiator. It is better to distribute them in several devices, installing one under each window opening. Let’s calculate how much the battery weighs. Cast-iron weighs much more, we have already figured that out. It remains to decide on the place to install the radiator.

The size of the window opening also affects the number of sections to be installed in the radiator. To use all the power of the heater its length should be wider than the window by at least 70-75%. And the radiator itself must be located at a distance of 8 to 12 cm from the window sill.

The dimensions of the cast iron radiator.

In the Soviet Union, the dimensions of cast iron radiators had a certain standard. In one section, the distance between the centers of the supply and return pipes ranged from 30 to 50 cm. The width of the section was not standardized and varied from manufacturer to manufacturer. Almost all modern batteries also have these standards. The most popular model among cast iron products is MS-140. (installed in many “Khrushchev” and 9 floors of 60-80s). Distance between the centers of the tubes is 50 cm; battery height 58.8 cm; width 9.3 cm; depth. 14 cm. The variety of dimensions of the batteries is due to the needs of customers.

How much do cast iron standard

What they have in common is the material used, namely cast iron. When mentioning cast iron batteries, the classic cast-iron radiators come to mind at once, which were installed and still properly serve in

  • Pre-school and school educational institutions;
  • Medical institutions (hospitals and clinics);
  • In all living quarters (dormitories, apartments, private houses and summer cottages);
  • Government and public organizations.

A classic example of a harmonica battery can be found everywhere.

In the vast majority of them is the model MS-140 or MS-90. Other models of mass production in the past period was not observed.

To be fair I will note that in past years in small series produced models Minsk-110, NM-140, NM-150, R-90, RCS and others. At present they are not produced, and the scope of their application was limited to the regions close to the manufacturer.

Famous movie characters had to wear radiators MS-140-500 series.

So what is the weight of one section of the cast iron battery of the old model? What is the value contained in the factory manual? And here the answer is not given by one figure, because the dimensions of the section play a role.

For example, cast iron battery series MS-140 has 2 varieties (interaxial distance):

Accordingly, if we are talking about the MC-140-300, the average weight of a cast-iron radiator rib is 5.7 kg. And if we are talking about MS-140-500, then one such section will show on the scales 7.1 kg.

Also quite often there is a series of MS-90. In comparison with the 140 series, the weight of the cast iron battery section of the old model is 6.5 kg at 500 mm.

The difference between the MC-90 and MC-140 models is the smaller depth of the section.

Do Batteries Weigh When They Are Charged? Crazy Battery Life-Hack (They Bounce!)

Let’s summarize the intermediate result: we have determined 3 different weights of the most common series (MS-90 and MS-140). 6.5 kg, 5.7 kg and 7.1 kg respectively. Can these values be considered final?

Normative document, regulating the order of cast iron radiators production

The existing standard (GOST 8690-94) describes main parameters and dimensions of radiators produced. Regarding the weight of the sections, this standard contains the value of specific weight equal to 49,5 kg/kW.

The standard specifies block and cast iron heating radiators, designed for operation in heating systems with a temperature of the coolant up to 150 ° C (423 K) and an overpressure of up to 0.9 MPa (9 kgf/cm2).

To dismantle such a monster, it must first be sawed.

In fact, the manufacturer must comply with the specified values, but the weight of an individual section is not regulated by GOST. In practice, it is expressed by the fact that products of different enterprises differ in weight.

As of the beginning of 2017, I know the products of several companies producing MS-140 radiators, their modifications and products of their own design:

  • Foundry and Mechanical Plant (Ukraine, Lugansk);
  • Heating equipment plant (Republic of Belarus, Minsk);
  • Boiler and radiator plant (Nizhny Tagil, Russia);
  • “Deckart” (Russia, Novosibirsk);
  • “Santekhilit” (Russia, Bryansk).

Let’s look at the range of products, and determine how much cast iron batteries from different manufacturers weigh.

Description of cast iron radiators

Cast iron radiators have been popular and in demand for two centuries. With the advent of more modern products made of steel, cast iron radiators were called old-style radiators. However, the status of obsolete devices does not prevent these models from occupying a significant share of the market of devices for heating.

Novelties that flooded this niche did not manage to fully displace the variety of batteries made of cast iron. The latter is a worthy competitor to modern models. Features, which they have, give them many advantages.

Production and construction

For the manufacture of 1 section, or, in other words, 1 rib of the radiator of the old type, cast iron is used as the material. Regardless of the size of the future battery, all sections are made separately.

Then the required number of finished sections by means of nipples are assembled into a single structure. Joints are necessarily sealed by means of paronite or rubber gaskets.

The advantages of cast iron

If you do not take into account how much a cast-iron radiator weighs, you can note a whole range of advantages of heating devices of this type

  • corrosion resistance;
  • resistance to chemically aggressive environments. the material is undemanding to the characteristics of the coolant;
  • durability;
  • High indicators of thermal radiation. the greater the number of sections, the higher the heat output of the heating device.

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

Different variants of radiators

Technical Specifications

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

An ordinary standard cast iron radiator has a power of 1 link is 170 watts. Cast-iron batteries can withstand heating over 100 ° C and operate successfully at an operating pressure of 9 atm. This allows the use of products of this type in central and autonomous heating networks.

Modern models

Manufacturers offer lighter versions of radiators made of gray cast iron. If 1 section of the Soviet radiator MS140 weighs 7.12 kg, 1 section of the model Viadrus STYL 500 of Czech production weighs 3.8 kg, and its inner volume is 0.8 l. This means that a Czech 10-link radiator filled with heat transfer fluid will have a mass of (3.8 0.8) × 10 = 46 kg. This is 40% less than the weight of a filled MC 140 battery, consisting of the same number of cells.

In Russia, cast-iron radiators of lightweight design are also produced. Under EXEMET brand there are produced MODERN radiators, 1 section of which weighs 3.3, and its inner volume is 0.6 litres. These tubular cast iron radiators are characterized by a relatively low heat output, which requires an increased number of links. The radiators are designed for floor installation.

Cast iron vintage radiators are growing in popularity. These are floor models, manufactured by the technology of artistic casting. Because of the voluminous complex patterns, the weight of the cast iron radiator section is significantly increased, it reaches 12 kilograms or more.

Service Life

In houses built before the revolution, cast-iron radiators installed more than 100 years ago still work. Modern heating devices made of this material are also designed for dozens of years of unrepaired operation.

Longevity is due to the strength of cast iron, resistance to heat and pressure. cast iron radiators do not rust during the period when the heating medium is drained from the network and the inside surface of the radiator is in contact with the air.


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

Manufacturers offer models with different characteristics

  • Battery depth is from 70 to 140 mm in the standard version;
  • The width of the section varies from 35 to 93 mm;
  • section volume. from 0,45 to 1,5 l depending on the dimensions;
  • The height of the heater in the standard version. 370-588 mm;
  • axle spacing is 350 or 500 mm.

Disadvantages of cast iron radiators

Cast iron products have many positive aspects, but as with everything they have their disadvantages:

Cast iron models are difficult to install auto system. room temperature control. This is due to the fact that even after the radiator is completely turned off, it will continue to heat the air, thanks to its inertness of heat transfer.

Due to the large volume of coolant, after turning on the battery, it will take more than 30 minutes to heat up. And the room itself will not get warm during this period of time.

Very high weight in comparison with counterparts from other materials. Weight of one section is 7.5 kg. And such sections come in 6 or more pieces. Therefore, when carrying and installing the cast-iron radiator you need help

All cast iron radiators are represented by products of the same appearance. This is due to the peculiarities of casting cast iron parts. In order to somehow diversify the models, some manufacturers put a picture on the outer surface of the radiator. At the same time the cost of the product increases more than 10 times.

Cast iron poorly withstands water hammer. According to the requirements of GOST 8690-94 a cast iron radiator must withstand a short pressure of 1,5 MPa.

Only 20 years ago cast iron water heating radiators could be found in almost every apartment, except for high-rise buildings of 9 16 floors. Now they have ceded the primacy to the aluminum devices, modified and became a luxury item “thanks” to the exorbitant price. Although there are inexpensive variants of heaters on the heating equipment market. Familiarized with the types and characteristics of modern cast iron batteries, let us list their real advantages and disadvantages.

Possess information about how much a cast-iron heating radiator weighs, it is necessary for many reasons. For example, if the radiators are bought for installation in an entire private home, you need to calculate the lifting capacity of the car transporting the radiators, and also need to be formed with the number of movers who will carry them into the house.

For clarity, you can compare the weight of radiators made of cast iron outdated models and modern substitutes made of other materials:

  • one section of typical cast iron radiators with a 500 millimeter center distance weighs 5.5 to 7.2 kilograms, and with a 300 millimeter center distance it weighs from 4.0 to 5.4 kilograms;
  • The weight of the original cast iron radiators can weigh from 3.7 to 14.5 kilograms;
  • A section of an aluminum battery weighs 1.45 kilograms with a 500 millimeter center distance and 1.2 kilograms with a 350 millimeter center distance;
  • bimetal devices with interaxial distance of 500 millimeters weigh 1.92 kg / section, and at 350 millimeters. 1.36 kg / section.

When repairing and replacing heating equipment in the house, its owners need to remember how much an old cast iron radiator weighs, in order to decide whether to take the outdated multisectional heating device to the street with their own forces, because you need to calculate their strength. But there is no such data.

The problem is that there are different models in operation. At the same time they have the same purpose, but different weight. Plus, the market in our country sells devices that stand out for their size and variety of shapes.

At this time, for example, the names of classic radiators made of cast iron are more than a few dozen, and models made in the style of design, and counting is difficult. At the same time, this parameter, as the weight of one part of the radiator made of cast iron, differs dramatically.

The answer for the impatient

For those who do not like to read for a long time, I will immediately indicate in the table the weight of the cast-iron battery section of the old model, as well as write how much the modern aluminum and bimetal analogues weigh:

Non-standard. from 3.7 to 14.5 kg/section

Anticipate your question about weight. why is there no exact data on cast iron? After all, you need this value to determine whether you can with their own hands remove the old 10-section radiator from the apartment or house?

The thing is that in operation there are models of different series, identical in purpose, but different in weight. In addition, the market sells a lot of models that differ in size and shape from each other. Only traditional cast iron radiators today more than two dozen titles, and design floor models and do not count.
