Power of the cast-iron radiator depends on the area of its external surface and consists in ability to give the heat energy at the highest temperature of the heat-carrier. In general, this value ranges from 80 to 200 watts per section. To calculate the required power, the following formula is used: per 25-30 cubic meters. м. Battery power should be 1 kW. In case there are several external walls, the power indicator increases.
In the majority on the market of Russia the domestic models are presented. This is due to the fact that the cost of transporting cast iron batteries account for a large part of its final cost. Of the main manufacturers we can distinguish:
- ChAZ. Cheboksary Aggregate Plant (Russia)
- Minsk Heating Equipment Works (Belarus)
- Kiran (Ukraine)
- Viadrus (Czech Republic)
The structure of cast iron radiators
Almost all cast iron products. complete set, consisting of individual sections connected by nipple sleeves. In their manufacture gray cast iron is used. Between the individual sections are installed gaskets of paronite. Horizontally, the water flow is always in the same direction. Vertically, the current flows through the channels, of which there are one or more. Depending on the number of vertical channels increases the area and capacity of the battery.
Because of the need to preserve the strength and surface area, manufacturers can not change the mass to power ratio much. Great weight of the battery means reinforced mounts.
Dimensions of one section
The weight of one section of an old-style cast iron radiator of Soviet production is almost seven kilograms, unlike the Czech model, one section of which weighs about four to five kilograms. Batteries MS. 140 are the most relevant and most often used for heating large rooms.
In this video, let’s look at the of cast iron batteries:
- distance between axes. 19.69 inches (500 mm);
- height. 23.15 inches (588 mm);
- depth. 5.51 inches (140 mm);
- length. 4.25 inches (108 mm);
- thread diameter. 1 inch with a quarter;
- weight. 14.77 pounds (6.7 kg);
- water capacity ≈ 1.5 liters;
- rated heat input at ΔT 70 0 C. 160 W;
- working pressure. up to 9 Atm.
These devices are manufactured in Minsk and Lugansk from cast iron. MS. 90 batteries are manufactured in Russia and are also very popular among the population.
Technical characteristics of MS. 90:
- thermal power. 130 W;
- fin spacing. almost 90 mm
- height. 600 mm;
- depth. 100 mm
- volume. 1,5 l;
- axial spacing. 550-600 mm;
- heating degree. 125 0 C;
- Operating pressure value. 9-12 Atm.
They are intended both for production and for living rooms. Batteries are assembled together with the help of clamps and rubber seals. Differences of devices from each other consist only in a color scale: Minsk heaters are red, and Lugansk ones are gray.
Russian and foreign manufacturers additionally coat the surface of their heating systems with an anti-corrosion coating, so they have a higher resistance to destruction and a glossier surface, which reduces the hydraulic resistance.
Types of devices by weight
It is customary to divide radiators into standard and nonstandard. Weight range of 1 rib at the former, with their characteristic interaxial distance of 300 mm and 500 mm, is 4-5.7 kg and 5.5-7.2 kg respectively. For non-standard, 1 section can weigh from 3.7 to 14.5 kg on average.
Another classification can also be applied. The currently manufactured and popular with consumers cast iron models can be divided into three main types
Classic radiators are easy to recognize by their name. They are always marked with the letters “MS”, followed by two numbers. the section depth and the center distance. One of the most common standard models
The weight of 1 section of the first is usually 7.1 kg, and the weight of 1 rib of the second is 5.7 kg.
Representatives of vintage type are now at the peak of popularity, despite the fact that they are the heaviest radiators of all. Weight of 1 fin can be 12 kg. Because of their heavy weight, vintage devices refer to appliances with floor standing. These radiators look very attractive. They are made by the technology of artistic casting, which makes them not just heating equipment, but a real decoration of the interior of the room.
Influence of the weight of the equipment
As already noted, the weight of the cast iron radiator section and the battery as a whole predetermines the principles of installation and the complexity of installation. Only starting from this parameter, you can determine the necessary carrying capacity of transport for delivery and a sufficient number of loaders and workers.
The heavy weight of the radiator makes installation and assembly a bit of a hassle
The equipment should not be moved alone. only by two people and with the utmost care and caution. Despite its weight and apparent strength, cast iron is quite fragile
Even a slight impact may cause microcracks on it. Subsequently, under the influence of the coolant these micro damages will increase, resulting in depressurization of the heating equipment.
But if the base of the wall is made of light porous blocks, it is practically impossible to do that. Under such circumstances it will be necessary to install the heating device on the floor.
The weight of a cast-iron battery, depending on the number of sections, is from 7.1 kg to 71 kg.
The cast-iron battery. one of the iconic inventions of the Soviet era. An ordinary heating device became the hero of jokes, the character of films Though what, one would think, could be so special about an ordinary heating device?
Since the invention of the water heating system in Ancient Rome, mankind has not advanced much in the quality of the heating of their own dwelling. The heating devices resembled the usual coils, but they did not retain heat for long and the houses of both ordinary citizens and the palace nobility were still cold and damp.

In 1857 in St. Petersburg in the workshop of Franz Karlovich San Galli the first example of a cast-iron battery was made, which is the ancestor of modern heating devices.
Depending on the number of sections, a cast-iron radiator weighs from 7.1 kg to 71 kg.
In form, it was not like those radiators that residents are accustomed to seeing in the apartments of apartment buildings. It was a pipe of large diameter, at the ends of which were installed disc-shaped protrusions, which were not part of the heating system. As a casting material, cast iron was not chosen by chance. In the 19th century the steel and iron-making industry was actively developing, so foundry workers and engineers knew a lot about their business: they valued the material for its resistance to external factors, for its “long life” and good thermal insulation qualities.
Thanks to these parameters, the cast-iron radiator has “caught on” in Russia. Changing shape, size and weight, it acquired today unchanged appearance and proven production technology.
Advantages of cast iron heating radiators
Cast iron radiators are very resistant to the aggressive environment of the heat-carrier. This is due to the physical parameters of this metal. Cast iron radiators can for a very long time not be affected by corrosion, even at high temperatures. In addition to this almost no harm is done to cast iron and various chemicals added to the coolant.
In the case of a clogged or leaking appliance, they are fairly easy to repair. Clogging occurring in the radiator can be caused by the properties of the coolant with large amounts of Ca and Mg salts. As a result of deposits on the inner wall of the device, it is narrowed, which leads to a deterioration in the rate of heating and normal heat transfer. Leaks in a cast iron radiator can result from worn gaskets between the sections. All the above problems are best solved during the summer preventive shutdown of the water supply.
Cast iron heaters can be used at high temperature and pressure ratings due to their low thermal expansion coefficient.
The heat output of the heater is high enough. To achieve the greatest effect from this property it is necessary to place special reflectors behind the cast-iron radiator.
Installation of cast iron radiator is easy, thanks to the fact that the radiator sections are connected by means of threaded joints and gaskets made of paronite. In the same way, the battery is connected to the pipe ends. A special wrench is used for the threads, with which it is possible to disconnect any section without removing the side.
Very long service life of the product, which is more than 50 years. The only thing is that during this time it is necessary to regularly remove deposits and replace gaskets.
How much does one cast iron radiator section weigh??
Despite the continuous development of technology in heating systems, cast iron radiators are still a common heating device.
Cast iron radiators have a lot of advantages over their more modern steel and aluminum competitors, which is why they have remained popular for almost two hundred years.
Weight of cast iron radiator sections from different manufacturers
To understand how much a cast iron radiator section weighs from different companies, it is necessary to get acquainted with their manufactured assortment:
- Nizhny Tagil boiler and radiator plant. This manufacturer provides a passport for each of its products, which specifies the number of sections. The company offers 4 cast iron models. At the same time, the exact weight of the section is: for radiators MC-140-M-300. 5.4 kg; MC-140-M2-500. 6.65 kg, MC-90 and T-90M models. 5.475 and 4.575 kg respectively.
- Belarusian Barelief. Mainly produces single-channel sectional radiators with a modern design. This manufacturer manufactures 9 models of cast iron batteries, whose accurate fin weight ranges from 3.7 kg (products 2K60P-300) to 6.7 kg (MC-140M).
- Russian Santekhilit. Now the enterprise is shut down, but its products are still sold in the distribution network. Exact weight of the fins of batteries ranges from 4,45 kg (models MS-85 and MS-110-300) to 7,1 kg (MS-140M).
It follows from this
To choose the right mounting principle, you need to know how much weight a section of cast-iron battery filled with coolant. For cast iron heating devices it is important to select the right number of brackets for wall mounting. If the walls are made of porous blocks or the house is built of CIP panels, the number of fixing points is increased in order to distribute the load more evenly.
Correct calculation of radiators and reliable installation is a guarantee of uninterrupted functioning of the heating system.
Can the brackets hold such a heavyweight: how much does an old cast iron battery section weigh?
Radiators are assembled like a construction set, they are made of a certain number of sections of the same size.
Sections are cast at the factory. Grey cast iron is used for production.
