Heat output of cast iron radiators ms 140

The kind of heating system you have is essential to keeping your house warm and comfortable during the winter. For many years, cast iron radiators have been a mainstay in homes due to their dependability and effectiveness in evenly dispersing heat throughout an area. The ms 140 model stands out from the others due to its special features and capacity for heat output.

The ms 140 cast iron radiator is well known for its extended heat retention capabilities when compared to other radiator types. This means that even after the heating system has been turned off, the radiator will continue to radiate heat once it has reached a certain temperature. Because of this feature, they’re a great option for homeowners who want to reduce their energy expenses without sacrificing comfort levels inside.

In order to achieve ideal heat distribution, the MS 140 radiator’s design maximizes the surface area in contact with the surrounding air. This design element not only speeds up the heating process but also ensures a more even temperature throughout the area, doing away with the cold spots that are frequently caused by other heating techniques.

The longevity of the MS 140 cast iron radiator is one of its main benefits. These radiators are made of durable cast iron and require little upkeep over many decades of use. Investing in MS 140 radiators provides homeowners with long-term reliability and peace of mind, in contrast to other heating systems that may require frequent repairs or replacements.

Selecting the appropriate heating system is crucial for guaranteeing comfort and energy efficiency, regardless of whether you’re building a new home or remodeling an existing one. The MS 140 cast iron radiator is a superior option for insulation and heating because it blends traditional style with contemporary efficiency. We’ll go into further detail about the features and advantages of the MS 140 radiator in the sections that follow in order to assist you in making an informed choice for the heating needs of your house.

Characteristics and features

Their simple yet effective coolant, which even dissolves or removes metals, is the key to their widespread appeal in our nation’s centralized heating networks. 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 in there in addition to a massive amount of dissolved chemical elements. Cast iron is the only alloy that is unable to endure all of this. Stainless steel and this work well together as well, but we have no idea how much such a battery will cost.

MC-140: an enduring classic

The low cost of the MS-140 is also a secret to its appeal. Although the price of a single section varies significantly between manufacturers, it is roughly $5 (retail).

Advantages and disadvantages of cast iron radiators

It is evident that a product with several decades of market experience has certain special qualities. Cast-iron batteries have several benefits, such as:

• Low chemical activity, which ensures a long service life in our networks. Officially, the warranty period is from 10 to 30 years, and the service life is 50 years and more.
• Low hydraulic resistance. Only radiators of this type can stand in systems with natural circulation (in some still put aluminum and steel tubular).
• High temperature of the working medium. 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 in MS-140 and MS-90 the heat capacity of one section is comparable to aluminum and bimetallic ones. For MC-140 the heat output is 160-185 W (depends on the manufacturer), for MC 90 – 130 W.
• Do not corrode when the coolant is discharged.

• High thermal inertia. It can take an hour or more for the MS-140 section to warm up. And all this time the room does not get warm. But on the other hand, it is good if the heating is switched off, or a conventional solid fuel boiler is used in the system: the heat accumulated by the walls and water maintains the temperature in the room for a long time.
• Large cross-section of channels and collectors. On the one hand, even bad and dirty coolant will not be able to clog them for several years. So cleaning and flushing can be done periodically. But because of the large cross-section in one section "fits" more than a liter of coolant. And it needs to be "driven" through the system and heated, and this is an unnecessary cost of equipment (more powerful pump and boiler) and fuel.

Drawbacks that are "pure" also exist:

• Heavy weight. Weight of one section with a center distance of 500 mm from 6 kg to 7.12 kg. And since you need usually from 6 to 14 pieces per room, you can calculate what will be the mass. And it will have to be carried, and also hung on the wall. That"s another disadvantage: complicated installation. And all because of the same weight.
• Fragility 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 brittleness leads to not the highest working pressure: 9 atm. Pressurizing – 15-16 atm.
• Necessity of regular painting. All sections come only primed. You will need to paint them often: once a year or two.

Scope of application

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

Technical details of the Lugansk plant’s radiators

A radiator with a flat face plate, model number RD – 100 500 – 1,2, is available at the Lugansk plant. The table below lists its technical specs.

Calculation of the number of sections

Precise determination of the number of sections in a heating battery is a long time business. It is necessary to take into account the region, material of walls, what windows-doors, how many windows in the room, what is their area, warm downstairs room or cold, etc.д. If you need a methodology for exact calculation, look here, and approximately calculate can be based on the area of the room. It is believed that on average to heat 1m 2 area requires 100 W of heat. Knowing the area of your room, you determine how much heat will be needed: multiply the area by 100W. Then divide by the heat output of the selected radiator model.

For instance, we will place the Bryansk factory MS-140M-500-0.9 in a 12 m 2 room. The section’s thermal capacity is 160 W. Compute:

• Total heat needed 12m 2 * 100 W = 1200 W
• How many sections 1200 W / 160 W = 7,5 pcs. We round up (always in the big side – it is better to let it be warmer) and we get 8 pcs.

The radiators have distinct technical features even though they share the same name, MS-140. The truth is that they are produced according to industry standards in several nations. But this is good for the user because it allows you to select the option that best fits your needs. Additionally, there is a noticeable difference in a few metrics.

Knowing how much heat cast iron radiators like the MS 140 model can produce is important information when it comes to insulation and heating your home. These radiators are essential for effectively and efficiently distributing heat throughout your room. The MS 140 is a dependable option for heating your home because of its distinctive design and material composition, which maximize heat emission. Homeowners can ensure comfort and energy efficiency in their living spaces by making informed decisions about their heating systems by understanding the specific heat output capabilities of this radiator.

Technical characteristics of cast iron radiators MS 140

Cast iron radiators MS 140 are still in use in heating systems decades after they were first introduced. Given the consistent market demand for these devices, it makes sense to provide information about their specifications and installation, both of which will be covered in this material. Let’s schedule a time to get it done. When you find it most convenient?

Technical characteristics of batteries MC 140

At the time, a comprehensive GOST 8690-94 was developed to regulate all product parameters for the manufacture of this type of radiator. It states that batteries were made in five standard sizes, with center-to-center measurements of 300, 400, 500, 600, and 800 mm. The cast-iron heating radiators with dimensions that comply with GOST 8690 are displayed in the table below.

In the past, apartments as well as office or commercial buildings have been observed to have these devices in all possible sizes. Examining the features of the two most "popular" sizes—500 and 300 mm—that are still in demand is reasonable. These days, other changes are extremely uncommon and are only produced upon request.

The following table displays the primary technical specifications of the cast iron radiator MS 140 with center distances of 300 and 500 mm.

After examining every feature, conclusions regarding the benefits and drawbacks of the heating devices under consideration can be made. The following are their benefits:

1. Durability. It is not less than 30 years.
2. Heat output. Despite the outdated design, the cast-iron radiator MS 140 shows good values of thermal power.
3. Unpretentiousness. Gray cast iron, from which the devices are made, is not subject to corrosion and calmly tolerates poor coolant with a high oxygen content.
4. Undemanding maintenance. It is not superfluous to flush the channels of the product once every 2 years, but if this is not done, the MC 140 will safely work further on. Only the heat transfer rate will begin to decrease.
5. Inertness. It is both a plus of batteries and their disadvantage. The plus is that after the heating is turned off, the device still gives heat to the room for a long time.
6. Affordable price.

Let’s talk about the drawbacks, which are numerous as well. The devices’ prolonged heating is caused by their inertness, which also precludes the use of thermal heads for regulation. Other people exist:

1. Large capacity of the coolant. This affects the speed of heating and cooling of the system, and also forces to spend a lot of thermal energy to heat a large volume of water.
2. Heavy weight The installation of the radiators is influenced by the size of the products. It is not easy to fix them on walls made of porous lightweight materials, which are very popular nowadays.
3. Low working pressure threshold. This makes it impossible to install it in the systems of high-rise buildings.
4. Fragility. Wall-mounted cast iron radiator MS 140 500 is afraid of shocks, as it has thin walls. Cracks at the slightest freezing of water from the frost.
5. Unprofitable appearance compared to more modern analogs of cast iron batteries.

Recommendations for selection and installation

The choice of this kind of radiator essentially comes down to figuring out how many sections and what size are needed to heat a given space. The necessary heat output should be known to you or roughly calculated using the square footage, and you should account for some wiggle room when using the heating radiators. Based on the assumption that one square meter requires 100 watts of thermal energy, a room measuring 10 square meters will require 1 kW of heat. The device’s sections, MS 140 500 – 1000 / 160 = 6.25, require 7 pieces.

An increasing coefficient from 1.5 to 2 should be applied to the thermal capacity value for northern regions, and a decreasing index equal to 0.7 should be applied for southern regions.

Radiator mounting is done in line with the plan on the exterior wall.

Steel and cast iron brackets are the two varieties of brackets used to mount MS 140 batteries.

The brackets come in pairs that are welded with a strip; these work best when mounted on porous walls. They are able to be fastened to the surface in multiple places.

Conclusion

Because of their advantages and longevity, cast iron radiators MS 140 are commonly used in residential buildings with minimal interior design requirements, but they are also frequently found in commercial and industrial settings. They can be installed in utility rooms, different technical rooms, and outbuildings for heating purposes in private homes.

How the heat output of a cast-iron radiator is calculated?

One of the main parameters of the device for space heating is its heat output. But no less important in the installation of the heating system and such indicators as heat capacity and thermal inertness of the material from which the radiators are made. Cast iron radiators, which are used mainly in centralized heating systems of multi-storey buildings, have a high thermal capacity, but they are compact enough, withstand high pressure of the coolant and are not afraid of rust. Massiveness of cast iron and large volume of heat carrier in each section (section MS 140 weighing 7.5 kg contains 4.2 liters of water) provides cast iron radiators with greater heat capacity than heating batteries made of other materials, so the temperature in the room rises and falls gradually. For example, the heat output of a cast iron radiator MS 140 is much lower than that of a modern aluminum or bimetallic radiator, but it keeps the heat much longer.

How to choose a cast iron radiator

When selecting radiators, which performance attributes ought to be taken into consideration? Above all, these are:

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

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

The form of the radiator that was purchased needs to be given special consideration. It is no secret that the stigma associated with cast iron radiators stems from the fact that many people associate them with the "cast iron harmonica" that was played under the window in their early years. In fact, the well-known "ribbed radiators" have a tiny and ineffective heating surface area (heat output); thus, this indicator is 0.23 square meters for a portion 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 for such systems massive supply pipes are used. In addition, to heat the water to the calculated temperature of 90 degrees Celsius, the heating system must be operated in a lower temperature mode. Only high capacity steam boilers are suitable. Therefore, in private houses, the heating system sometimes operates 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 batteries, it is deprived of many of their disadvantages. So, the radiator of Minsk production 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 radiators, a radiator constructed from them is actually a heating panel that provides a broad directional heat flux. Other producers also offer a large selection of these radiators.

The benefit of contemporary cast iron radiators is that many models let you gather batteries in the right amount from different sections.

Engineers’ calculations of the necessary heat capacity per square meter of the room are used to form the number of sections of radiators sold in assemblies (e.g., Conner, STI Breeze, and some others).

For instance, you can purchase two radiators with four (6, 8) sections each or one radiator with 4-6, 8–12 sections.

Real heat output of the radiator section

As was previously mentioned, radiators’ capacities, or heat output, must be specified in their technical passports. However, why does it appear that the boiler is heating the house as it should and the radiators are installed in compliance with all regulations, but the house is still cold a few weeks after the installation of the heating system—or even earlier? Radiators’ actual heat transfer may be decreasing for a number of reasons.

Viadrus cast iron radiator (Czech Republic)

These are the stated heat transfer and heating surface area indicators for the most popular cast iron radiator models. These numbers will be necessary in the future for instances where we need to determine the actual power of a radiator section.

As previously mentioned, a cast-iron radiator’s heat output will be lower than what is indicated in the passport when used for medium- or low-temperature heating systems (such as 55/45 or 70/55). Consequently, its actual capacity needs to be recalculated using the following formula to avoid making a mistake with the number of sections:

Coefficient of heat transfer, or K.

F is the surface area heated;

°Ρ (0,5 x ( t inh. + tout. ) – tin.); ∆ t – temperature head

Tinh is the water’s temperature when it enters the radiator.

Toutlet, the temperature of the water at the radiator’s output;

Tin: the typical temperature of a room.

At 90 g of incoming coolant temperature, 70 g of output coolant temperature, and 20 g of room temperature.

20 – 60 = ∆ t = 0,5 x (90 + 70)

The following is the coefficient K for the most popular cast iron radiators:

Even one section of an average cast iron radiator (M-140-AO) with an area of 0.299 square feet and an incoming water temperature of 90 grams and an outgoing water temperature of 70 grams will produce less heat than what is stated. This is caused by heat losses in the supply pipes as well as other factors (like decreased pressure) that are unpredictable in a lab setting.

Thus, at a temperature of 90/70, the heat output of the section with an area of 0,299 sq. sq. m. м. will be:

Since most cast iron radiators have a coefficient of 1.3, multiplying this number by it results in 163, 254 W, as opposed to the declared 175 W. This is because the heat output is always specified with a reserve.

If the water entering the radiator is not heated above 70 degrees (and the outgoing coolant, respectively, cools down to 60-50 degrees), the difference in figures will be even greater. For this reason, it is advisable to ascertain the true thermal parameters of your heating system before making any purchases of new radiators.

How to save money on heating?

The first rule of reasonable economy is to remember what you should never save money on! Radiators should always be taken with a reserve, because it is possible to reduce the room temperature by reducing the water temperature in the system or by using shut-off valves. And if the real heat output will be lower than the manufacturer"s statement – the rooms will be cool at best. By the way, cast iron radiators Conner, which are not bad by most parameters, in real operation have heat output 20-25 percent lower than it is stated in the passport

1K60P-500 Radiator (Minsk)

As previously mentioned, the heat output may vary from what is stated because the water temperature in the heating system is significantly lower than the "standard," or the temperature at which factory tests were carried out, and the stated radiation power is only achievable in a laboratory. Assume that a radiator MS-140 section (power 160 W specified) will generate a maximum power of 50 W at a water temperature of 60/50 degrees (and more, "the boiler does not pull"!). Furthermore, if you follow the technical passport and choose to install five heating sections, you will only receive 250 W rather than 800 W (160 x 5).

But it is possible to anticipate this circumstance and even capitalize on it! The radiator’s radiating surface should be larger the lower ∆ t (i.e., the temperature of the water-heating medium), according to the calculations above. As a result, a radiator measuring 0.5 m x 0.520 m in height at ∆ t 60 and 0.5 m x 1.32 m at ∆ t 30 is adequate to radiate 1 kW.

MS-140M2 is a "classic" cast iron radiator.

Heating costs can be decreased, though, specifically by lowering the carrier temperature and expanding the radiator’s radiating area or number of sections.

Indicators influencing the calculation of the number of sections

It is important to consider the technical aspects when choosing a radiator for a specific space. The computation will vary, for instance, between a room with a corner and one without one, as well as between rooms with various window sizes and ceiling heights. The computation for a room that is not a corner and a corner will differ. The following factors are the most crucial ones considered when calculating the radiator’s required power:

• the area of your room;
• floor;
• ceiling height (above or below three meters);
• location (corner or not corner room, room in a private house);.
• whether the radiator will be the main heating device;
• there is a fireplace in the room, air conditioning.

There are more significant aspects to take into account. How many windows does the room have? What kind of windows are they—wooden, double-glazed with one, two, or three panes—and how big are they? Has extra wall insulation been installed, and if so, what kind—internal or external—has been installed? It matters if a private home has an attic, how well-insulated it is, and other factors.

Conner cast iron radiators (China)

For every cubic meter of space, 41 W of heat energy are required, according to SNIP. It is possible to consider the room’s area rather than its volume. One door, one window, and one exterior wall in a standard room measuring 10 square meters will require the radiator to have the following heat output:

• 1 kW for a room with one window and an external wall;
• 1.2 kW if it has one window and two exterior walls (corner room);
• 1.3 kW for corner rooms with two windows.

Actually, heating uses one kilowatt of heat energy:

• In the rooms of houses made of brick with wall thickness of one and a half or two bricks, or of timber and log houses (area of windows and doors up to 15%; insulation of walls, roof and attic) – 20-25 sq. m. м
• In corner rooms with walls made of timber or brick not less than one brick (area of windows, doors up to 25% ; insulation) – 14-18 square meters. м
• In the rooms of panel houses with internal cladding and insulated roof (as well as in the rooms of an insulated dacha) – 8-12 sq. м
• In a "dwelling car" (wooden or panel house with minimal insulation) – 5-7 sq. km. м.
