Cast iron batteries ms. Which is better to choose cast iron radiators

classic battery

Harmonicas known to all have been used for a long time. Modern technologies made it possible to change the approach to solving effective system heat transfer using latest materials and designs. But, oddly enough, accordions did not leave the shelves of hardware stores. Consumers do not want to part with them, especially since manufacturers have begun to change both production technologies and equipment on which batteries are produced. That is, the approach to their manufacture in Lately changed a lot. That is why we chose the appropriate topic for our article - “Cast-iron heating radiators MS 140 500 - specifications».

Why is this version of heating batteries today never left the assembly line and was not forgotten. Because:

• Firstly, cast iron is a metal that practically does not interact with water. That is, the processes of corrosion of metals do not occur inside the device.
• Secondly, this material practically does not react to low quality coolant. And in our domestic heating networks this happens quite often.
• Thirdly, good inertial thermal conductivity. For example, MS 140 is still warm one hour after the coolant supply is turned off and gives off thermal energy, by volume equal to 30% of the face value. In such a situation, for example, the steel radiator has almost cooled down.
• Fourthly, a huge service life. Installed many decades ago, they are still in operation, regardless of conditions and loads. Although manufacturers guarantee only a thirty-year milestone. And this maximum term. But practice confirms 100 years of service.
• Fifthly, it is a fairly large internal volume. This is the very reason why MC 140 500 radiators do not require constant cleaning and purging. Scale and various debris simply do not have time to fill the space of the cavities.
• Sixth, the complete absence of electrochemical corrosion of the material. That is, a cast-iron radiator can be combined with any materials. Be it plastic, steel, copper or another option.

Specifications

So, we have come to the main topic of our article are the technical characteristics of the cast-iron battery brand MS 140 500.

1. First of all, it should be noted that this is a purely sectional model. heating appliances. Therefore, many specifications carry the criteria of one section.
2. Radiators of this brand can withstand coolant temperatures up to +130 C.
3. Pressure up to 9 atmospheres.
4. At the same time, the pressing pressure is up to 15 atm.
5. Each section has two channels.
6. The volume of one section is 1.35 liters.
7. Its heat dissipation is 175 W (not the highest figure).
8. The width of one section is 98 mm, the height is 500 mm (this is indicated in the brand of the model).

For the production of batteries, gray cast iron is used, but for the production of nipples, malleable. Gaskets made of heat-resistant rubber are installed between the sections.

Knowing the technical characteristics of the MC 140 500 radiator, you can choose it for a specific room. And, more precisely, you can choose the number of sections to provide the normal required temperature regime inside the room. For this, the following ratio of two indicators is usually used: one kilowatt of thermal energy is required per ten square meters of heated area. This ratio is valid under one condition - the height of the ceilings in the house should not exceed 2.8 m.

Let's use this ratio to calculate the number of sections in a cast-iron radiator, which will be installed in a room of 20 m². It turns out that this will require 2 kW of thermal energy. Since the heat transfer of one section is 0.175 kW, we can carry out a calculation that shows that for this room you will need a radiator with 11.4 sections. Round up and get 12 sections.

Of course, this is an approximate calculation, because we have neglected various additional factors that relate to the design of the building itself. For example, the number of windows and doorways, the quality of the thermal insulation, especially the thickness of the heaters used, the number of storeys of the building, the climatic conditions of the region, and so on. But as an approximate calculation, this ratio can be used.

Definition of technical parameters

Heating cast iron radiators, including the MS 140 500 brand, did not give up their positions. Someone may say that these heaters are much inferior to other models in their external design. We will not argue, but we note that manufacturers are trying to change them appearance. Modern cast iron heaters are ready to compete with other analogues in terms of a presentable appearance. Moreover, they are made using the technology of casting iron, they can be modified beyond recognition. Go to building stores, visit manufacturers' websites, and you will simply be surprised at the variety of forms where you can find just works of art.

So, cast-iron radiators MS 140 500 will still serve us.

A cast-iron radiator is a classic heating device that, over many years of use in houses and apartments, has established itself as a reliable and durable device. Heating appliances from this resistant material there are several types. So which cast iron radiators are better?

To answer this question, it is necessary to consider the pros and cons of each type.

What are the advantages of cast iron batteries?

Today cast iron batteries are considered obsolete devices. A lot of modern heating radiators made of steel, aluminum or two of these metals at the same time (bimetallic) have appeared on the market. However, cast iron batteries are still in great demand. Especially often they are installed in apartment buildings from centralized system heating. This is because in such houses as a coolant is used process water, the cleaning of which no one is strongly concerned about. As hot water flows through pipelines, it picks up various contaminants. The coolant enters the batteries of apartments from big amount alkalis and grains of sand, acting as abrasive substances. All this can clog and destroy radiators from the inside. No other type of battery, except for cast iron, can properly serve for more than 50 years in such difficult conditions.

The advantages of cast iron radiators include:

1. Corrosion resistance.
2. High level of thermal inertia. Cast iron takes longer to cool than other materials. The radiator retains up to 30% of heat an hour after the heating system is turned off. Batteries of other types in such cases retain only 15% of heat.
3. Durability. Although the developers talk only about 10-30 years of serviceable service, in practice this device can work up to 100 years. For such long work device, it is better to periodically clean it and replace the intersection gaskets.
4. Large internal cross-section, due to which the need for cleaning rarely occurs.
5. Cannot cause electrochemical corrosion. That is, cast-iron batteries can be safely attached to both steel pipes and plastic ones.
6. High working pressure (from 9 atmospheres). Cast iron radiators tolerate water hammer well.

The disadvantages of cast iron batteries are their considerable weight (one section weighs about 5-6 kg) and long time heating (but they cool down for a long time).

If an old cast-iron radiator cracked from frost, then ice accumulated inside, which further increased the already heavy mass. It is not possible for one person to carry such a burden out of the house. The walls of cast iron batteries are specially made so thick that they do not break, since cast iron is a brittle alloy. When installing the battery, it is better to use reliable and strong fasteners.

Types of cast iron radiators

To decide on the question, “Which radiators are better?”, It is necessary to consider their types.

In appearance, radiators are divided into:

• old-style batteries;
• new generation devices;
• design retro models.

By the number of channels in one section thermal devices from cast iron there are single-channel and two-channel.

By structure, cast iron batteries are divided into:

1. Sectional.
2. Solid cast.

Solid radiators are rare. Usually these are designer models or devices. custom sizes. These radiators have undeniable advantage — high level reliability. A leak can only occur if the cast iron begins to break down.

Most batteries are made up of sections. Such a structure is very convenient, as it allows you to choose a radiator with just such a number of sections that would provide the most comfortable temperature conditions in the room.

The selection of battery power is carried out depending on the location of the room and the number of window openings. Indoors with one outer wall and one window of 10 sq. m. area to create a comfortable microclimate requires a battery with a capacity of 1 kW. For a room with one window opening and two outer walls, this figure is 1.2 kW., and for a room in which there are two windows and two outer walls, 1.3 kW is needed. Such data is often used in independent calculations. Professionals calculate more and more difficult, but more accurate.

Old style radiators

Old-style cast iron batteries do not have the most attractive appearance. However, this does not mean that their installation will spoil the interior of the room. Today it is fashionable to cover radiators decorative grilles, boxes and screens. Their level of heat transfer is reduced, but outwardly everything looks much more aesthetically pleasing.

Compared to radiators manufactured in Soviet times, modern batteries have reduced spacing between sections, making them neater.

The main advantage of old-style radiators is affordable price. The cheapest devices are made in Russia. Batteries made in other countries (for example, Belarus) are slightly more expensive, but in addition to the price, they differ in size.

Cast iron batteries of the old model are unpretentious in operation. If the owner of the apartment does not dislike their appearance, then he can simply paint them to match the color of the walls.

Cast iron radiators of the old type are called "MS". The name is followed by a dash followed by a number. The first number indicates the depth of the sections, and the second - the distance between them (for example, MS-140M-500, MS-110-500).

When choosing a cast-iron radiator, it is imperative to take into account the depth of its section. First you need to measure the depth of the window sill. After all, if the battery is located in a niche under the window opening, then it should not stick out from under the windowsill. Firstly, this way you can spoil the whole appearance, and secondly, the radiator will interfere with approaching the window. For example, the MS-110 model manufactured by the Santekhlit plant has a small section depth, only 11 cm. Such a battery can easily fit under any modern plastic window sill.

Which radiators are better - domestic or imported? IN Western countries heating systems are of better quality and cleaner, therefore, cast-iron batteries manufactured by Western developers, when working with domestic coolants, can quickly fail. Dirt (rust, various chemical elements) accumulates inside the batteries, narrowing the opening for the passage hot water. As a result, their thermal efficiency decreases and they may stop heating the room.

The MS-140M-500 radiator is a domestic old-style cast-iron battery with a section depth of 140 mm and a center distance of 500 mm. It is actively used in houses, apartments and industrial premises with a water heating system. Maximum temperature coolant should not exceed 120 degrees Celsius. These batteries have been produced since Soviet times.

The MS-140M-500 radiator is sectional and two-channel. The number of sections can be from 4 to 7. The capacity of one section is 1.45 liters. Rated heat flow - 0.16 kW. The battery is completed with 2 through and 2 deaf plugs, 4 gaskets made of heat-resistant rubber are installed inside.

The power of one section of the MS-140M-500 cast-iron radiator is 160 watts. The operating pressure of the battery is 9 atmospheres, and the pressure test is 15 atmospheres.

How much does the MS-140M-500 cast-iron radiator weigh? Its weight depends on the number of sections. So the mass of one section is 6.7 kg. A four-section battery weighs 28.2 kg with dimensions of 388 * 588 * 140 (D * W * T), and a cast-iron radiator with 7 sections - 48.9 with dimensions of 853 * 588 * 140.

Cast iron batteries MS-140M-500 meet all the requirements of GOST and TU. They are made of cast iron grade SCH 10.

The Russian company JSC "Santekhlit" produces more models MS-140-300, MS-110-500, MS-110-300 and MS-85-500. They have similar technical characteristics.

New generation radiators

Cast iron batteries of the new generation look much more attractive than older devices. They have modern look and visually resemble aluminum or steel radiators. They have a flat front and Smooth surface. Some products already have factory enamel applied, other models are sold without it, 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 being produced in Russia, Belarus and Ukraine.

Cast iron radiators KONNER HIT, Modern - eurodesign

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

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

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

designer batteries

These radiators are made in "Retro" style. They are not hidden, but flaunted as a stylish element of decor. But such models are not suitable for every interior. They fit elegantly into classic style, Venetian, Gothic. Externally, designer radiators look like products of past centuries. Various drawings and bas-reliefs are depicted on their surface. Often they are mounted on legs. These retro batteries are featured in a wide range: Guratec (Germany), Viadrus (Czech Republic), Demir Dokum (Turkey), Roca (Spain), Rococo (England). The release of designer batteries is also carried out by Russian companies, such as Exemet and RetroStyle.

For retro radiators big size row. The distance between the axes can be from 30 to 90 cm, the depth of the batteries is from 10 to 23.5 cm, and the width of the sections is 4-8.1 cm.

Turkish products are in great demand. Popular among the population designer radiator Alpine Air History 600 with a power of 143 watts. It can be applied indoors for various purposes. Additional sections can be easily attached to it, increasing the heating power. At the factory, it is covered with a layer of primer and high-quality varnish, tested with a hydraulic pressure of 15 bar. All sections of the radiator are heated evenly. Due to the thickness of the material, the sound of water circulation inside the heater is practically inaudible. The heater is decorated with an unobtrusive ornament of water plants in french style"Art Nouveau". If desired, you can find models with a center distance of 350, 500,600 and 800 mm.

The Demir Dokum Retro 600 battery impresses with its design. The surface of each section is made in palace style end of the 18th century. All adjustment and shut-off valves(faucets, valves) is also made in retro style. The heater looks powerful, but elegant. It is used for connection to water or steam system heating. Design feature this appliance– the increased diameter of internal through openings thanks to what it is not afraid of blockages and water hammers. How much does this design weigh? The mass of the battery is 76.4 kg, and the heated area is 14.4 square meters. m. The production uses high-quality cast iron, which is not afraid of mechanical damage, corrosion and aggressive environments. Demir Dokum Retro radiators are also available with center distances of 500 and 800 mm.

Another stylish Turkish-made radiator is the DEMRAD Retro 600. The cast-iron forging with intricate ornaments evokes the rich mansions of the 18th century. With their help, you can create a mysterious atmosphere in the room with a hint of wealth. This radiator is painted in rich colors of blackened silver or antique gold. What are the technical characteristics of this heater? The weight of one section is 11.4 kg, the volume is 2.6 liters, the heat output is 126 W., test pressure- 13 atmospheres. The surface of the battery is painted quality paint, which keeps long years. Can be connected to heating systems different types. If only part of the structure fails, then you won’t have to change the entire radiator, it will be enough to replace the damaged sections.

The domestic company Retro Style is also engaged in the production of vintage-style radiators. They resemble products of the 18th and 19th centuries. The choice of the buyer is offered several collections, each of which is different exclusive design and matches one of luxury styles: baroque, empire, classicism, rococo, etc. At the request of the customer, the battery can be painted in desired color(chocolate, gzhel, red with gold, etc.).

Methods for installing a cast iron radiator

Since cast-iron radiators have considerable weight, when choosing a model, it is better to think over the installation method in advance. The battery can simply be put on its feet. Many designer radiators are already available with legs. If we are talking about other models, then you can also select and purchase legs for them separately.

If the battery is planned to be attached to the wall, then it is recommended to do this on a load-bearing wall. You can mount the heater on the partition, but first it must be further strengthened. For this, the fasteners must be as reliable as possible. It is better to use hooks or brackets.

Summarizing

There is no single answer to the question "Which heating radiators are better?". It all depends on the conditions under which the batteries will be operated, and the budget. For a new private house with individual system heating, you can purchase a foreign-made battery of a new sample. She will fit into modern interior and will last a long time. For houses with classic interior, if there is an opportunity not to save, you can choose a designer model that will successfully fit into the interior and emphasize the taste of the owners. For apartments with central heating it is recommended to install old-style domestic radiators. The best way- cast-iron radiator MS-140M-500, the technical characteristics of which speak for themselves. Such a heater is inexpensive and will last for many years even in difficult conditions.

After decades from the moment of its appearance, cast-iron heating radiators MC 140 continue to serve in heating systems to this day. Since these devices are in steady demand in the market, it makes sense to talk about their parameters and installation, which will be done in this material. Let's set a day when we can finish everything. Whenever it's convenient for you?

Specifications for MC 140 batteries

For the manufacture of this type of radiators, at one time, a whole GOST 8690-94 was developed, which regulates all the parameters of the product. In accordance with it, 5 standard sizes of batteries were produced with center distances of 300, 400, 500, 600 and 800 mm. The table below shows cast-iron heating radiators with technical dimensions in accordance with GOST 8690.

Previously, all standard sizes of these devices could be seen not only in apartments, but also in production or administrative buildings. It is advisable to review the characteristics of the two most "running" sizes of 300 and 500 mm, which are still in demand. Other modifications are now very rare, and they are made only to order.

The main technical characteristics of the MC 140 cast iron radiator with a center distance of 300 and 500 mm are shown in the following table.

Having studied all the characteristics, we can draw conclusions about the advantages and disadvantages of the considered heating devices. Their advantages are as follows:

1. Durability. It is at least 30 years old.
2. Heat dissipation. Despite the outdated design, the MC 140 cast iron radiator shows good thermal output.
3. Unpretentiousness. Gray cast iron, from which the devices are made, is not subject to corrosion and calmly tolerates a bad coolant with a high oxygen content.
4. Maintenance undemanding. It is not superfluous to flush the channels of the product once every 2 years, but if this is not done, then the MC 140 will continue to work safely. Only the heat transfer coefficient will begin to decrease.
5. Inertia. It is both a plus of batteries and their minus. The advantage is that after turning off the heating, the device gives off heat to the room for a long time.
6. Affordable cost.

Now about the shortcomings, of which there are also many. The same inertia of the devices causes their prolonged heating and excludes the possibility of regulation with the help of thermal heads. There are others:

1. Large capacity of the coolant. This affects the rate of heating and cooling of the system, and also makes it necessary to spend a lot of thermal energy on heating a large volume of water.
2. Considerable weight products affect the installation of radiators. They are very difficult to fix on walls made of porous lightweight materials, which are very popular in our time.
3. Low working pressure threshold. This makes it impossible to install it in high-rise building systems.
4. Fragility. The wall-mounted cast-iron radiator MC 140 500 is shock-resistant because it has thin walls. Cracks at the slightest freezing of water from frost.
5. Unpresentable appearance compared to more modern analogues of cast iron batteries.

Selection of this type batteries comes down to determining the required number of sections for heating a particular room and a suitable size. To do this, you need to know the thermal power or approximately calculate it by quadrature, and take heating radiators with some margin. If we take as a basis that 100 W of thermal energy is needed for each m2 of area, then 1 kW of heat will be needed for a room of 10 m2, and sections of the MS 140 500 - 1000 / 160 = 6.25 device, 7 pieces are taken.

For the northern regions, an increasing coefficient from 1.5 to 2 must be applied to the value of the thermal power, and for the southern regions, a decreasing index equal to 0.7.

Installation of radiators is carried out to outer wall in accordance with the diagram.

For fastening batteries MS 140, 2 types of brackets are used: steel and cast iron.

There are paired strip-welded brackets that are best used when mounting on a wall made of porous materials. They can be attached to the surface at several points.

Conclusion

Considered cast-iron batteries MS 140, due to their merits and time-tested reliability, are used in residential buildings with low requirements for the interior, more often in industrial and domestic premises. In private houses, they can be placed in utility rooms and various technical rooms or for heating outbuildings.

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.

Let's talk about features

Now, it's time to bring to your attention the technical characteristics of cast iron radiators.

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 calculation formula required amount 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 round it up better - 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. On the photo you can see different types fasteners.

For example, pin and corner brackets are used for sectional radiators. The first ones 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 mount you need 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. No need to rip off right away 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 low. In addition, they proved their suitability for a whole century, both in the USSR and in Europe. Big Advantage- this long term their operation.

Cast iron radiators are radiators that have come down to our time from the distant 70s of the last millennium. Today they are more modern, it is almost impossible to distinguish them from bimetallic or aluminum radiators covered with enamel. Cast iron radiators are capable of operating with coolant temperatures up to 110 0 C.

A rather large size and impressive weight is offset by inertia, which allows you to adjust the temperature. They are ideal for any room, reliable and durable, can be used with any boilers and heat carriers. Many are interested in the question - how many kilowatts are in one section of a cast-iron radiator? You will find the answer to this question below.

Cast iron heating radiator

Pig-iron radiators M-140

M-140 type radiators have quite simple design and easy to maintain. The material used in their manufacture is cast iron. It has a high resistance to corrosive processes and can be used with any coolant. The low level of hydraulic pressure allows the use of radiators for both gravity and forced coolant circulation systems. The high threshold of resistance to hydraulic shocks allows them to be used both in two-story and nine-story buildings. The advantages of the M-140 are ease of maintenance, reliability, long service life and low cost.

Cast iron radiators MS-140-500

Widely used for heating buildings with coolant t in the range of 130 0 C and a pressure of 0.9 MPa. The capacity of one cavity is 1.45 l, the volume of the heated area is 0.244 square meters. The material used for the manufacture of sections is SCH-10 (gray cast iron).

Important! When choosing a radiator for housing, be sure to pay attention to its characteristics and make all kinds of calculations in advance, since it will be almost impossible to exchange the purchased goods.

Pros and cons of using cast iron radiators

Stylized cast iron radiator

Any heating system that exists today has both pluses and minuses, consider them.

The nominal value of the thermal power of each section is 160W. Approximately 65% ​​of the released heat flow heats the air that accumulates in the upper part of the room, and the remaining 35% warms lower part rooms.

1. Long period of use, ranging from 15-50 years.
2. High level of resistance to corrosion processes.
3. Possibility of use in heating systems with gravitational circulation of the coolant.

1. Low efficiency of heat transfer index correction;
2. High level of labor intensity during installation;

Important! In order not to run into a problem during installation, be sure to consider the above pros and cons of cast iron radiators. Their installation is not cheap, but repeated installation work will require a lot of funding.

Calculation of sections (cavities) of radiators

And so, how many kW are in 1 section of a cast-iron radiator? To calculate the number of sections and their power, it is necessary to determine the V of the room, which will later appear in the calculations. Next, select the value of thermal energy. Its meanings are as follows:

1. heating 1 m 3 of a house from panels - 0.041 kW.
2. heating 1 m 3 of a brick house with double-glazed windows and insulated walls - 0.034 kW.
3. heating 1 m 3 of premises built according to modern building codes- 0.034 kW.

The heat flux of one cavity MS 140-500 is 0.160 kW.

Next, carry out the following mathematical operations: the volume of the room is multiplied by the heat flow. The resulting value is divided by the amount of heat released by one cavity. The result is rounded up and we get the desired number of sections.

How many kilowatts cast iron section? Each type of radiator has different meaning, which the manufacturer calculates during their manufacture and indicates it in the accompanying documentation.

Let's make an approximate calculation according to the available data.

The room has the following data: room type - panel house, length - height - width - 5x6x2.7 m, respectively.

1. We calculate the volume of the room V:

V \u003d 5 x 6 x 2.7 \u003d 81 m 3

1. The amount of heat needed:

Q=81*0.041=3.321 kW

1. Based on this, the number of radiator sections is as follows:

n= 3.321/0.16=20.76

where 0.16 is the thermal power of one section. Specified by the manufacturer.

1. We round the value up, based on which the number of required sections is 21 pieces.
