Advantages of cast iron radiators

It is possible to use cast-iron radiators of the MS-140-500 brand in buildings of any story and with any heating system, including gravity heating systems, due to their high corrosion resistance and lack of demand on the quality of the heat carrier.

This is further made possible by the radiators’ exceptional strength, which enables them to tolerate the hydraulic shocks that come with central heating with ease. Gray cast iron is very brittle, so the products need to be carefully shielded from any potential knocks and falls.

Large internal section volumes and broad channel cross-sections make the heating device easier to clean and contribute to low hydraulic resistance and clog prevention.

The radiator’s set design makes it possible to put together a heating appliance that is specifically made to heat a given space. For cast iron radiators, manufacturers typically offer a limited warranty of three to five years. Nevertheless, they have a 40–50 year service life on average.

The radiators from various manufacturers have slightly different technical characteristics. All of their parameters, despite various deviations, fall within the bounds of GOST 31311-2005 and technical specifications 4935-005-00288372-05. Consequently, the purchaser has the option to select a heater that better meets their unique needs than others.

Pros and cons of cast iron radiators MC-140

The primary benefit of these batteries is their dependable and long-lasting construction. Manufacturers typically specify a service life of roughly 50 years, but in reality, this is frequently longer.

  • The possibility of installation in any heating system is an undoubted plus of the device, which is characterized by its unpretentiousness, for example:
  • Cast iron radiator can withstand a large baric load of 10-12 atmospheres;
  • possibility of operation at high temperature of the heat carrier and high pressure in the system;
  • Thanks to wide internal cavities and channels, the possibility of clogging is reduced and the resistance to water hammer is increased;

It’s also important to discuss this product’s drawbacks:

  • Brittleness, non-plasticity and hardness of the material contribute to the possibility of damage to the radiator, which can not withstand mechanical loads.
  • The design is very massive and has a large mass, the total weight of a small number of sections can exceed 60 kg.
  • Often radiators from the factory are delivered only with a layer of primer, which means that you will have to paint the product yourself, which is not quite easy.
  • And one more disadvantage – unsightly appearance.

Main characteristics of radiators MS-140

– The device’s "MC" name’s letter designation is still unclear, and the numbers "140" stand for the depth of each section, which is 140 mm. For instance, the designation MS-140-500 designates a section with a depth of 140 mm and a center-to-center distance of 500 mm. One of the most popular types of radiators installed in apartments is this one.

– The less common models MC-140-300, whose center-to-center distance differs from that of the earlier model. They are less effective at dissipating heat and are utilized when window sills are low.

While ductile iron or steel (08KP or 08PS) is used to make sockets and naples, gray cast iron is used to cast sections. The tightness of the product is preserved by the ring gaskets.

Cast iron radiators are produced in Russia and its surrounding nations, and they essentially share the same technical specifications.

Cast-iron radiators are made at the OOO "Dekart" plant in Novosibirsk, the Nizhne-Tagil Boiler and Radiator Plant, and the Bryansk-based OAO "Santechlit" company. Products from the Lugansk foundry-mechanical and heating equipment plant in Minsk have also received positive reviews.

Advantages and negative sides of cast-iron radiators

Cast iron products have their advantages and disadvantages, just like any other heating appliance. According to experts, these products’ primary benefits include the following features:

  • Reliability – manufacturers for such devices give a 50-year warranty.
  • The products themselves, especially with proper care for them, are able to last much longer.
  • Versatility – cast iron radiators can be installed in different variants of heating systems: central, autonomous.
  • Small hydraulic resistance makes it possible to use them for systems with central circulation.
  • Low probability of corrosion processes.
  • Affordable price.
  • Resistance to aggressive heat transfer medium.
  • Resistance to high temperatures – they can withstand even 130 degrees Celsius.
  • Radiant heating – a cast-iron radiator is better than a steel one at heating objects located nearby.

Regarding the drawbacks of the MS models product, some experts hold the following opinions:

  • Large mass – one product with the center distance weighs about 6-7.5 kg, the whole radiator in this case will weigh from 36 to 75 kilograms.
  • The need for maintenance – cast iron, even after priming, must be painted every 2-3 years.
  • Mechanical shocks can cause cracking of the structure.

Certain characteristics of cast iron batteries can work to the product’s benefit or detriment. Broad channels: this characteristic increases the amount of water required but also helps to prevent system blockages.

Features of radiator MS-140-500

Cast iron MS-140 radiators are intended for use in heating buildings of all kinds, from private homes to commercial and industrial structures, with an interaxial distance of 500 mm. They are resistant to aggressive heat transfer fluids and have a good heat output. Thought to be the most humble kind of radiator, cast iron "accordions" are determined to stay in the heating equipment market.

Among the strongest radiators are those made of cast iron. The metal’s chemical and physical properties are to blame for this.

The extended lifespan of cast iron radiators is their primary benefit. Cast iron resists corrosion well because it reacts reluctantly with water and aggressive substances. It also does not affect the top layer that is shielded from it by paint and primer. For the most part, cast iron is resistant to thinning and deterioration even when not sealed. In certain instances, the service life of these radiators can surpass that of the building itself.

Cast iron radiators MC-140 with center-to-center spacing have a heat output per section ranging from 140 to 185 W. This is a fairly good indicator that lets cast iron heat batteries successfully compete with other kinds. Many domestic factories currently produce cast-iron batteries, which are here to stay and will never go off the shelves of plumbing supply stores.

Owing to advancements in cast iron molding techniques, the final goods exhibit exceptional durability and low maintenance requirements.

Distinctions between cast-iron heating batteries and other widely used battery types in terms of technical attributes.

What benefits are offered by MC-140-500 cast iron radiators?

  • Resistance to aggressive coolant – centralized heating systems do not spare even the most robust modern radiators. Cast iron practically does not react with corrosive and aggressive compounds;
  • Large internal capacity – thanks to this radiators practically never get clogged or clogged. Also the internal volume contributes to the reduction of hydraulic resistance;
  • Long service life – warranty from manufacturers reaches 10-20 years. As for the actual service life, it is up to 50 years and even more, it is only necessary to competently care for the radiators and in time to paint them;
  • Long heat retention – if the heating is switched off, cast iron will retain and give out heat for a long time, heating the premises and rooms;
  • Affordable cost – The price for cast-iron radiators MC-140-500 starts from the mark of 350-400 rubles for one section (depending on the manufacturer).

Let’s enumerate a few drawbacks:

A primary drawback of cast iron radiators is their susceptibility to water hammer, wherein they fall short of their bimetallic equivalents.

  • High weight – perhaps, this is one of the most important disadvantages. One section weighs more than 7 kg, so the weight of a battery of 10 sections is more than 70 kg;
  • Difficulty in installation – if aluminum or steel radiators can be mounted independently, the cast iron radiator will have to be worked on by two or three people. In addition, for fixing to the wall you need a good sturdy fastener (and the walls themselves should not crumble under the weight of batteries);
  • Lack of resistance to high pressure – cast iron batteries are oriented for operation in autonomous heating systems (installation in low-rise houses connected to centralized systems is allowed).

Additionally, we should draw attention to the high inertia of cast-iron batteries MS-140, which means that it takes a while for the coolant supply to warm up the system.

Although there are certain drawbacks, consumers are still drawn to cast-iron batteries because they offer the best value in terms of cost, performance, and features.

Cast-iron radiators MC-140 with a coolant pressure maximum of 9–10 atmospheres can be utilized in both independent and centralized heating systems. The coolant can reach +120 to +130 degrees; cast iron is not affected by temperature overloads of this kind. It is important to avoid giving it strong shocks as this could cause it to break.

Systems with both forced and natural coolant circulation can utilize MC-140 radiators. Cast iron can function in any situation and can operate in an open or closed system. What matters most is that the heating parameters don’t go above the amounts listed in the passport information. The only thing that makes operations difficult is the requirement for routine maintenance; keep an eye on the paint coating’s condition and prevent pockets of corrosion from forming.

Installation instructions

The radiator MS-140-500 is a heating device that you can choose from; installation instructions are provided below. Connecting the device to the common house system will be the most challenging part of the project. As a result, you ought to get in touch with the house’s maintenance office.

The area where the radiator will be installed must be ready in advance. The mounts that serve this purpose are installed at the same level as the cast-iron radiator that will be hung. Paint the radiator only after it has been installed and connected; otherwise, you will need to do the work twice. Nipples, which are cylindrical couplings with threaded sections oriented in the opposite directions, should be used to connect sections to sections. Installed in between the sections are gaskets. Special grooves on the inner surface of the nipple are necessary for the coupling with the splines.

Materials and technical characteristics of cast iron radiators MC-140-500

Gray cast iron CH 10 GOST 1412-85 is used to mold the radiator sections. In accordance with GOST 6357-81, radiator sections are connected via radiator nipples, which are fitted with pipe thread.

To tighten the radiator’s sections Left and right threads are located on opposing ends of the nipple. The ductile iron of KCh30-6-F grade of GOST 1215-79 and steel 08 KP or 08 PS of GOST 1050-2013 are the materials used to make the nipples.

Installed in between the sections is the nipple. A straight-tipped wrench is used to rotate it. The nipple’s sections are tightened together because its threads run in different directions. It is accessed through the radiator’s exposed hole.

With the aid of a ring gasket, the resultant connection is sealed. Heat-resistant rubber ITP or ITC, matching TU 38 105376-82, or ring 9833-73 / 18829-73, is the material used for the gasket.

In the event that installing a rubber gasket is not feasible, using soot to seal the joints is acceptable. Either olive oil or dried wax is used to impregnate soap. A plug made of gray cast iron casting СЧ 10 GOST 1412-85 closes the radiator end.

Formulas for calculating heater power for different rooms

The height of the ceiling affects the formula used to determine the heater’s power. When a room’s ceiling height is less than three meters, this dependency appears like this:

  • S – area of the room;
  • ∆T – heat output of the heater section.

When calculating for rooms with ceiling heights greater than three meters, the formula is used.

  • S is the total area of the room;
  • ∆T – heat output of a single battery section;
  • h – ceiling height.

These easy formulas will make it fairly accurate to determine how many heater sections are needed. Use the previously provided formulas to ascertain the section’s actual heat output before inputting data! This computation works well with incoming coolant that is 70˚ C on average. A correction factor needs to be considered for other indicators.

  • 3 x 4 x 2.7 = 32.4 cubic meters.

Let’s now determine the heat capacity needed for heating: The room’s volume multiplied by the amount needed to heat one cubic meter of air is:

Determine the necessary number of radiator sections by rounding the value upward and taking into account each section’s actual capacity. Consequently, 5, 3 is rounded to 6, and 7, 8 to 8 parts. The areas of the rooms are added together to determine the heating of adjacent rooms that are not divided by a door (such as a kitchen that is divided from the living room by an archway without a door). You can round down in a room with double-glazed or insulated walls (double-glazed windows and insulation reduce heat loss by 15-20%), but add one or two sections "in reserve" in a corner room or high-floor room.

Why the radiator does not heat?

But sometimes the capacity of sections is recalculated on the basis of the actual temperature of the coolant, and their number is calculated taking into account the peculiarities of the room and set with the necessary reserve … and the house is cold! Why this happens? What are the reasons for this? Can this situation be corrected? The reason for the decrease in temperature may be a reduction in the water pressure from the boiler room or repairs at the neighbors! If during the renovation your neighbor has narrowed the riser with hot water, installed a "warm floor" system, started heating a loggia or a glazed balcony with a winter garden – the pressure of hot water entering your radiators will, of course, decrease.

How to choose a cast iron radiator

When selecting radiators, which performance attributes ought to be taken into consideration? To begin with, it is:

  • working pressure;
  • the operating temperature in the heating system for which the heat output is calculated;
  • heat output;
  • the heat emitting surface area;

The first of these indicators determines the pressure of the coolant (water) that the radiator can withstand. The higher the storey of the building, the stronger it should be. The second indicates the temperature at which the coolant is supplied to the radiator and at which it leaves it for subsequent heating. So 90/70 means that the water entering the first section of the radiator has a temperature of 90 degrees Celsius. and the one coming out of the last section of the heating system is 70 deg. Heat output is an indicator of how much heat a section of the radiator gives off while the water in it cools down from the inlet temperature (e.g. 90 degrees Celsius).) to the outlet temperature (e.g. 70 degrees Celsius).)

Paying close attention to the radiator’s shape is important. It’s no secret that the stigma associated with cast iron radiators stems from the fact that many people associate them with the "cast iron accordion" they played with as kids under the window. Undoubtedly, the typical "ribbed batteries" possess a diminutive and ineffective heating surface area (heat output); for instance, this amount amounts to 0.23 square meters for a segment of the well-known radiator MS 140. м.

Part of the heat of the incoming coolant is lost "on the way" from the heating boiler to the water heating radiator, because massive supply pipes are used for such systems. In addition, to heat water to the calculated temperature of 90 degrees Celsius, it is necessary to heat water to a temperature of 90 degrees Celsius. Only high capacity steam boilers are suitable. That is why in private houses the heating system sometimes works in a lower temperature mode.However, modern cast iron radiators and in appearance and, accordingly, in parameters can differ significantly from their predecessors-"accordion". Retaining all the advantages of traditional cast iron radiators, it is deprived of many of their disadvantages. For example, the Minsk-made radiator 1K60P-500 is assembled from flat plates, each of which has a small heating area (0.116 m) and low power (70 W).

In contrast to ribbed batteries, a radiator constructed from them is actually a heating panel that provides a broad, directed heat flow. Some manufacturers also offer a large selection of these radiators.

One benefit of contemporary cast iron radiators is that a lot of them allow batteries with the necessary capacity to be assembled from separate sections.

Conner, STI Breeze, and other assembled radiators, for instance, are made up of several sections that are intended for rooms of varying sizes. These sections are created by engineers using the necessary heat capacity per square meter of the room as a basis for their design.

One radiator with 4-6-8-12 sections, for instance, or two radiators with 4 (6, 8) sections each are both available for purchase.

Section counting

The arrangement of the space determines how many sections there should be. The floor area is the primary factor, but there are other significant factors as well, like zoning, floor, niche dimensions, ceiling height, and the quantity and presence of double-glazed windows.

Experts advise installing heating radiators beneath each window in a room with multiple windows. The installation will cut down on heat loss significantly. The formula for determining how many heating radiator sections are needed is shown below.

Crucial! Additional heat losses can have an impact on corner apartment owners’ comfort. As a result, these rooms require stronger cast iron radiators.

They are supplemented with one or two sections.

Although there are numerous technical methods available, a straightforward yet reasonably accurate formula is used to determine the number of sections needed for standard rooms.

Thus, to perform a calculation, multiply 100 W by the room’s area and divide the result by the radiator’s single section’s heat output.

Crucial! The easiest way to solve a fractional number is to round it up. There will be a tiny power reserve as a result.

You can start installing the cast-iron battery right away if the computation is accurate.

Characteristics and features

Their simple secret to popularity is that they are such a coolant in our nation’s centralized heating networks that even metals dissolve or are erased. It contains sand, rust fragments that have fallen off pipes and radiators, "tears" from welding, bolts that were forgotten during repair, and a ton of other things that are unknown how they got inside in addition to a massive amount of dissolved chemical elements. Cast iron is the only alloy that is unable to endure all of this. Additionally, stainless steel and this work well together, but we have no idea how much such a battery will cost.

The MC-140 is an enduring classic.

Another factor contributing to MC-140’s appeal is its affordable price. Although the price varies greatly between manufacturers, one section typically costs roughly $5 (retail).

Advantages and disadvantages of cast-iron radiators

It is evident that the product possesses some special qualities because it has been off the market for many decades. Among the benefits of cast iron batteries are:

  • Low chemical activity, which provides a long service life in our networks. Officially the warranty period from 10 to 30 years, and the service life – 50 years and more.
  • Low hydraulic resistance. Only radiators of this type can stand in systems with natural circulation (some still put aluminum and steel tubular ones).
  • High temperature of the working environment. No other radiator can withstand temperatures above +130 o C. Most of them have the highest limit – +110 o C.
  • Low price.
  • High heat output. All other cast iron radiators have this characteristic in the "disadvantages" section. Only at MS-140 and MS-90 the heat capacity of one section is comparable with aluminum and bimetallic ones. For MS-140 the heat output is 160-185 W (depends on the manufacturer), for MS 90 – 130 W.
  • Do not corrode when the coolant is drained.

Section depth differences between MS-90 and MS-140

Certain attributes are advantageous in certain situations and disadvantageous in others:

  • Large thermal inertia. It can take an hour or more to warm up a section of MC-140. And all this time the room is not heated. But on the other hand, it is good if the heating is switched off, or if a conventional solid fuel boiler is used in the system: the heat accumulated by the walls and water maintains the room temperature for a long time.
  • Large cross-section of channels and collectors. On the one hand, even a bad and dirty heating medium cannot clog them even in a few years. Therefore, cleaning and flushing can be carried out periodically. But because of the large cross-section in one section "fits" more than a liter of coolant. And it must be "driven" through the system and heated, and this – extra costs for equipment (more powerful pump and boiler) and fuel.

Drawbacks that are "pure" also exist:

  • High weight. Weight of one section with a center distance of 500 mm from 6 kg to 7.12 kg. And since you usually need from 6 to 14 pieces per room, you can calculate how much weight it will be. And this will have to be carried and also hung on the wall. This is another disadvantage: complicated installation. And all because of the same weight.
  • Brittleness and low working pressure. Not the most pleasant characteristics. With all the massiveness of cast iron products must be handled with care: they can burst on impact. The same fragility leads to not the highest working pressure: 9 atm. Pressurizing – 15-16 atm.
  • Necessity of regular painting. All sections come only primed. Paint them will need to paint them often: once a year or two.

There are times when thermal inertia is advantageous.

Field of application

As you can see, there are drawbacks in addition to the very real benefits. Once everything is summed up, you can identify the field in which they are used:

  • Networks with very low quality of the heating medium (Ph above 9) and a large amount of abrasive particles (without strainers and filters).
  • In individual heating when using solid fuel boilers without automatics.
  • In networks with natural circulation.
