Flat radiators: steel, old model, construction, installation

Cast iron sectional radiators

The first development of cast iron batteries was carried out almost 150 years ago by our compatriot. A few years later, the Americans received a patent and finalized the design. Radiators gained popularity after the appearance of the central heating system, and their mass production was established during the industrial revolution.

The batteries, which were used in the USSR and now remain in many houses, have the MC 140 brand. The value "140" is the power delivered by one section. The working and test pressures of the battery are 9 and 18 atmospheres, respectively. The number of sections is from 4 to 10.

Today, cast iron radiators are gaining popularity again, thanks to the improvement of their construction and design.

The advantages and disadvantages of this type of batteries are approximately the same.

Long service life (over 50 years);
Affordable price;
Resistance to mechanical damage;
Corrosion resistance;
High abrasive wear. Pebbles and sand in the water do not do much harm to the battery from the inside;
Heating efficiency with the maximum number of sections.

Large weight and bulkiness;
Possibility of depressurization of joints;
Accumulation of rust inside during long-term use;
Unpresentable appearance;
Difficulty in integrating radiators into autonomous heating systems, the impossibility of saving on the coolant;
Difficulty cleaning.

Convection radiators

Convector type radiators are connected to a conventional heating system. The hallmark is a completely different way of functioning.

Panel, sectional or tubular radiators give off heat to the environment from their hot surface, which allows you to heat the room.

Convectors work differently. Their design provides for the presence of many thin air channels located between the ribs of the plates.

The air in the room passes through them, at the same time heats up, becomes lighter and rises upward, which ensures continuous movement and mixing of air, i.e. constant heating

This allows you to evenly warm up the room, which is not an important hindrance even the presence of many interior items and partitions

They are lightweight, compact and reliable because made of copper, steel and aluminum - corrosion-resistant materials
A relatively small volume of water is required in the system.
They heat up quite quickly and also cool down quickly
Such radiators allow heating rooms with high ceilings.
A heating system with convector radiators allows you to make savings when purchasing equipment. Those. in such a system, pipes of a small diameter are used, a sufficiently low power of the circulation pump and the coolant itself has a small volume.
Very simple installation, which can be carried out without special skills.
There is a huge selection of appearance options for the convector body. What can be a beautiful addition to your interior. Replacing the housing is very simple and only takes a few minutes.
Increased security, i.e. the heat exchanger is completely closed by the casing.

All batteries have functional drawbacks. The convector radiator is durable, economical, safe and beautiful enough. The only drawback is the high price, because they are made from high-quality and expensive materials.

To correctly give preference to one or another type of radiator will help such a characteristic as power. It is easy to calculate it: in a room with a ceiling height of 300 cm and one window, 100 watts will be needed to heat one square meter. When the room has two outer walls, add another 20%. If there are two outer walls and two windows, add 30%. When the window exits to the north side - you should throw 10%. An important factor will be the installation of radiators, because no matter how good you buy the batteries, if they are installed incorrectly, there is still zero sense from this.

There are certain rules for installing radiators:

batteries are always placed under windows
their length must correspond to the length of the window, or at least half the length
in the corner room, an additional pair of radiators can be installed along the outer wall
it is better to mount heating risers in the corners. This will ensure that they warm up and prevent blackening of the wall and the formation of mold.
they must be available at all times.

When choosing heating radiators, you should rely on the technical characteristics of the radiators and the heating system itself, as well as the budget. With proper study, you can always find a middle ground for yourself.

Let's summarize

In conclusion, we can say that focusing on the varieties, materials and the process of work of one type or another, you are guaranteed to select heating radiators that are most suitable for your expectations and the heat supply system. Follow these simple rules to help you take your time choosing a decent option at no extra cost:

1. Determine the characteristics of your home: area, ceiling height, number of window and door openings. Also consider the heater and heating medium. An important criterion is an individual or trunk system. 2. Having studied the properties of the types of radiators, choose the one that, in your opinion, will complete the task without the occurrence of negative accidents and damage. Do not be tempted by the low price, pay attention to the brand and reputation of the manufacturer. 3. Look for real user reviews of a specific brand on the Internet. It is better to do this on specialized forums. It will not be superfluous to see photo and video reviews. 4. For installation of the purchased radiator, contact a specialist. Do not try to do it without experience in this area. This is fraught with disruption of the functionality of the entire system and sad consequences, up to and including a battery breakthrough. 5. When choosing a design, do not forget about the direction of the style of the rest of the room furnishings. Do not expose the radiator to a foreign object.

Choosing the right attractive and functional heating element is not an easy task, but a persistent search will surely provide a positive result.

Steel panel radiators

These radiators are rectangular panels:

The panel radiator is made of two steel sheets welded together. Vertical grooves are extruded in the sheets through which the coolant circulates.

Steel panel radiators are made of one, two or three panels. Vertical pipes are welded to the rear sides of these panels to enhance convection:

Pipes to enhance convection at panel radiators

Panel radiators are manufactured with a height of 300 ... 900 mm, a length of up to 3 m, and a depth of 60 ... 165 mm.

The plus of panel radiators is a low weight, so they can be mounted alone, powerful brackets are not needed, and the wall material can be not only concrete or brick, but also wood and some kind of frame sheathing (as you probably guessed, the comparison carried out with cast iron radiators).

In panel radiators, it is easy to control the temperature of the coolant, due to the low thermal inertia of these heating devices.

Cons of steel panel radiators:

panel heating batteries are designed for low pressure (6-8 atm. - working and up to 13 atm.test), hence their sensitivity to water hammer;
the inner surface of the panels is subject to corrosion;
poor hygiene, since dust and cobwebs accumulate between the panels, and it is very difficult to get to this muck.

From all of the above, we draw conclusions: it is more correct to install panel radiators in private houses and take care of the quality of the coolant.

Design features and variety of steel heating radiators

The high manufacturability of steel does not require proof. This pliable, strong, flexible and malleable material lends itself well to welding and also conducts heat remarkably. So steel is suitable for radiators in many ways.

Steel radiators are available in two types:

panel;
tubular.

Panel type radiators

In the middle of this device are one, two or three panels. Each of them consists of two steel flat sections welded along the contour for connection. The plates are stamped, after which oval vertical channels are formed on them - paths for the coolant. The production of these radiators is simple - roller welding joins the stamped workpieces. After that, the finished parts are fastened together in two pieces with the help of pipes.

The device is a steel convector radiator.

To increase heat transfer, manufacturers often equip panels from the inside with U-shaped ribs. For their manufacture, thinner sheets of steel are taken than for panels. The ribs help increase convection. If several panels are connected in a row, then they are covered with covers on both sides. Depending on the number of heating and convector panels located inside the radiators, there are the following types of them.

Type 10 Is a single-row radiator without convector and without cladding.

Type 11 - single-row radiator with one convector, without upper grille.

Type 20 - double-row radiator without convector, with air outlet grille.

Type 21 - double-row radiator with one convector fins, closed by a casing.

Type 22 - double-row radiator with two convector fins, closed by a casing.

Type 30 - three-row, without convector fins, covered with a grill on top.

Type 33 - a three-row radiator with three convector fins, covered with a casing.

As you understand, its heat transfer will depend on the type of radiator. Radiators of type 10 and 11 do not have convection and are able to give off heat only by heating the air.

The finished radiator turns out to be quite narrow, which is very convenient for installation. The price of such products is very affordable, so the owners of their own houses prefer to install them.

Tubular radiators

Steel pipes welded together make up the core of this heater. However, it also serves as a body. Making such a radiator is not as easy as the previous one, but it undoubtedly has much more model variations. The most common classic option is a radiator similar to cast iron, but with many more channels for the movement of the coolant.

The number of channels that a pipe radiator can have.

Such a device is quite expensive, and it cannot be called a budget option. Rather, it is an option for a designer who is not constrained in funds.

All possible colors of pipe radiators.

His imagination, coupled with bright colors, original shapes and the entire range of sizes, makes such radiators a real highlight of a stylish and beautiful interior.

And more about the price: any bimetallic radiator of a well-known European brand is cheaper than a tubular radiator, even made in Russia.

The common minus of steel heating batteries

The “weak link” common to all steel radiators is oxygen susceptibility. Well, that is, they rust, as everyone knows.Moreover, they rust not so much from the outside as from the inside, when the coolant is drained from them.

This does not mean that steel batteries should be completely disowned. You just need to understand in which heating systems they should be installed. Steel batteries are suitable for closed systems. As a rule, this is in private houses.

That's all about steel radiators, I hope now you can decide exactly which heating radiator to choose.

When arranging a home with a heating system, special attention should be paid to heating devices, in particular, radiators. It is on them that the level of warming up the room largely depends.

Among the variety of such elements, I would like to note thin heating batteries. They are much lighter in weight than cast iron heat exchangers, which makes their installation easier and more convenient.

Criterias of choice

Flat steel heating radiators are not placed in systems with natural circulation of the coolant, since a large amount of working fluid is needed here. Such batteries work well in forced circulation schemes, but here it is necessary to correctly calculate the volume of the expansion tank and the capacity of the circulation pump.

When choosing a model, it is necessary to take into account the height and heat output. Low radiators are relevant for the characteristic height of the window sill (when it is not possible to install higher equipment). The lower the heater, the more evenly the heat is distributed, and a dense curtain is created.

Single-pipe wiring allows you to reduce installation costs, but here it is imperative to equip a bypass line. The shut-off valve will become a barrier for the coolant, it is necessary to ensure the rational return of the device. With a one-pipe scheme, the most advantageous is a diagonal connection, when the coolant is supplied from the top left, and the outlet is organized from the bottom right.

The width of the radiator is selected so that it covers 50-75% of the same parameter of the window opening. Narrow models are not able to create a dense heat curtain.

Heating radiator classes

There are 4 classes of heating devices:

Sectional type radiators are known to everyone. They are made of cast iron, aluminum, steel. There are models for the production of which two materials are used (usually steel and aluminum). Such batteries are called bimetallic. Sectional radiators are assembled from separate sections (sections), receiving at the output a heating device with the required power, given to them in the external environment during operation.

Sectional radiators are assembled from separate sections (sections)

Plate heaters are so named because they are made of several plates that are mounted on curved or straight pipes. The pipes, in turn, circulate a coolant (water). Another name for plate heating devices is convectors. They can be electrical and non-electrical.

Photo: tubular radiator in the interior

Tubular radiators are made of several tubes connected by collectors. They look pretty original. Such radiators are often found in apartments where the interior is made by professional designers. Pipes can be made of any size and shape, for example, in the form of a specific shape.

Photo: panel radiators of different sizes

Panel heating radiators consist of panels that receive heat from a heat carrier circulating in the space between them through channels formed by stamping. There are models with one, two and three panels.

Let's consider in more detail each of the types of heating radiators.

Plate radiators

Along with sectional, tubular and panel heating devices, plate heating batteries are also widely used.In terms of the level of heat transfer, they are second only to panel-type heating devices. But compared to them, they have a much lower price, they can operate at a pressure in the system of more than 10 atm (up to 17-20 atm) and allow hidden installation in floor niches.

Obsolete finned heater.

A significant difference between plate heating batteries and other types is in the way the room is heated. In all other structures, up to 70-80% of the power is spent on heat radiation and heating walls and objects in the room, from which the air is then heated. In the plate type, this power is used to heat the air directly and equip it with convection (mixing) in the middle of the room. Hence the second name for these heating systems - convector heaters.

Air heating is at the same time a positive quality and a minus, which predetermine the area of use of these devices. And the thing is that heating rooms to the required temperature with the help of heat radiation, although it takes more time, but the effect of it lasts longer, and for finding people, the conditions created are better suited from the point of view of comfort.

There is a heat-reflecting aluminum plate behind the heating device.

Ribbed ones, on the contrary, can in a short time warm up large air volumes to the required temperature, but at the same time they make significant air flows, which make discomfort for people present in a motionless position. Actually, this is the reason for their use in the corridors of public buildings, staircases, gyms, warehouses, etc. In other words, where there are large volumes of premises and there is a constant movement of people (or does not happen, as in warehouses).

Obsolete plate heater in the entrance of a house for housing

Design and types

The design of a plate heating radiator is based on one or several straight, U or W-shaped tubes, to which a lot of metal heat exchange plates are perpendicularly welded or otherwise fixed. The heat carrier moving through the tubes heats these plates, and they then transfer the received heat to the space of the room.

In most cases, the finished device is placed in the middle of a thin-walled body, which serves to protect it from burns and cuts against the sharp edges of the plates. The housing or casing also protects the fins of the heater from dust and damage from mechanical factors. However, there are models, mainly radiators made of steel with increased thickness of fins and trimmed edges, which are intended for operation without a casing, "as is."

Old ribbed battery.

Along with the shape and size, the following main types of plate heating batteries are distinguished.

By the material of the device: steel; copper; bimetallic in combinations: steel - copper, steel - aluminum, less often copper - aluminum.
By the number of pipes: single-pipe and multi-pipe with a manifold.
By the method of connecting to the backbone: with side and bottom connections.
According to the installation option, there are pendant heaters and built-in type in the floor niche. The latter are placed either specifically on the floor or on the insulation material.

Obsolete plate heating radiator.

If we talk about the pros and cons, then the obvious positive qualities include cheapness, high heat output and the speed of heating the air. And also reliability due to the small number of connectors. The most serious disadvantages: uneven temperature distribution across room levels and high requirements for cleanliness. Although, the latter is more correct to call the secret positive quality of steel plate heating radiators.

Finned heater, behind which there is an aluminum heat-reflecting plate.

Summarizing.The overwhelming majority of manufactured heating devices operate on the principle of convective air circulation. However, there are models with a built-in fan. Based on this, this raises the price and the overall energy consumption of the device, but by increasing the intensity of air mixing, it partly solves the problem of a sharp difference in temperature along the height of the room.

The most important characteristics of steel radiators

Heat dissipation

With heat dissipation, things are not bad at all - the heat transfer rate varies from 1200 to 1800 watts and even more. This parameter depends on the dimensions of the radiator, its brand and the type of a specific model. Note that a big advantage of these devices is their low inertia. They heat up very quickly and begin to give off heat to the room.

Operating pressure

The maximum working pressure for this type of radiator ranges from 6 to 10 atmospheres for plate radiators. This parameter is limited due to the ductility property of steel. However, tubular-type radiators can withstand higher pressure - from 8 to 15 atmospheres. All this means that steel radiators cannot be used in district heating systems. They will not be able to withstand the pressure of the central heating system.

Coolant quality

An important detail is how "gentle" the radiator will be in relation to the quality of the coolant. For steel, this is a real stumbling block - after all, it rusts so easily when air comes into contact with water. However, manufacturers are not giving up - they are trying to overcome this problem. Special inner coatings are applied for protection. But, unfortunately, this struggle often ends with the victory of corrosion. Therefore, it is better not to install steel radiators in an apartment of a multi-storey building. In the summer, the water will be drained, and rust will begin to eat the radiators.

Heat carrier temperature

The maximum hot water temperature that steel batteries can withstand is from 110 to 120 degrees.

Center distance.

Steel radiators can have both side and bottom connections. The center distance is important for radiators with a side connection. It determines how far the upper collector is from the lower one. This must be taken into account when installing the radiator. Steel panel radiators, depending on the model, type and manufacturer, can have a center-to-center distance equal to the height of the radiator minus 50 - 70 cm. For tubular steel radiators, the center-to-center distance ranges from 120 mm to 2930 mm.

dimensions

Now a few words can be said about external parameters, in particular, about dimensions. In length, panel-type radiators can reach 3 meters, their height is from 20 to 90 centimeters. A tubular radiator can be made in almost any length, and its depth is limited to 22.5 centimeters. Height varies from 19 to 300 centimeters.

Steel thickness.

Few people pay attention to this indicator, but manufacturers use steel of various thicknesses for the manufacture of steel radiators. This indicator can vary from 1.15 to 1.25 mm. It is clear that the thicker the steel, the better.

Durability

Thanks to the material of manufacture - strong and reliable steel - these radiators are able to live a long life without letting down their owners. Quality products with thick walls (0.12-0.15 centimeters) produced by reliable and responsible brands serve especially well.

Ease of installation

The installation of these heating devices is not very difficult. Moreover, it is very convenient that it is possible to choose a panel-type radiator with connection both from the side and from the bottom. In the latter case, the pipes can be hidden under the floor, and the temperature sensor is connected directly to the radiator.And the panels of the radiator itself can be connected in series or in parallel - both types of models can be found on sale.

Panel type radiator with bottom connection system.

Aluminum radiator

It is widely used to design a heating system in a private house. They became popular due to their design and high heat output. The cost of such radiators depends on the manufacturer.
Radiators of domestic manufacturers will cost less, but after getting acquainted with consumer reviews, it is worth giving preference to foreign counterparts, but their price is much higher.

When choosing an aluminum radiator for a localized system of your own home, you must adhere to a list of very significant conditions for selection and operation:

An aluminum radiator is the most susceptible to circulated fluid. It is required to strictly observe the required level of acidity of the water, otherwise such radiators will become unusable within several years;
Aluminum radiators have a threaded connection. which increases the risk of leakage;
The high heat output of aluminum radiators has a downside. When the radiators are heated, the warm air flow rises very quickly, which leads to a temperature difference between the floor and the ceiling.

Sectional aluminum radiator

This means that when choosing aluminum radiators, there is a need to make accurate calculations for the area of the room, since the floor can remain cold.

But aluminum radiators also have undoubted advantages:

Relatively low weight, which makes it possible to mount on drywall walls;
Sufficiently aesthetic appearance
The presence of special taps that allow you to regulate the temperature.

The relatively low price, good design and instant heat dissipation are the secret of the popularity of aluminum radiators.

These are quite acceptable radiators for a heating system in a private house. Observing strictly the norms of selection and use, such radiators will heat your cozy home for a long time.

Which heating battery to choose for your home

Shopping list? Don't like the look of the batteries in your home? Do you think their sharp corners and elevated surface temperatures are dangerous for your little child? Buy a screen for a radiator and install it - it will not take much time and will not require serious financial investments. Meanwhile, such a product is able to provide:

Plate radiators for heating: characteristics, photos. Heating radiators Plate heating radiator: features of the old ones.

With the onset of the warm season, it's time to think about the efficiency of the heating system. If it needs to be replaced, summer is the best time for installation work. At the height of the heating season, it will not be possible to replace the radiators.

Thin metal plates are set on the tubes. They are designed to increase the level of heat transfer between the heating element and the room air. Plate batteries are used in public premises and industrial buildings, industrial workshops. In frequency housing construction, they have not received proper distribution for a number of reasons. However, they are widely used for heating multi-apartment buildings, where centralized heat supply dominates. With good insulation of the building, a plate heater is able to maintain the air temperature at the proper level with a minimum consumption of thermal energy.

Important: there is an opinion that now a cast-iron radiator is worse than Soviet times.

Radiators are an integral part of heating systems if heated floors are not used instead. It is not always easy to combine their appearance with the interior. This can be made easier by using radiator shields. The screens are attractive in design and shape, so there is always something to choose from. What materials are the screens made of and which one is better to choose? This will be discussed in the article.A screen for a heating radiator has several purposes.

Modern heating radiators are of several types. Depending on the material from which they are made, these devices have different characteristics. That is why problems often arise with how to choose the right heating battery.

To decide which heating battery to choose, you need to pay attention not only to the size and appearance of the radiators, but also to their features.

Design and purpose of plate radiators

You can choose, buy and install any radiator, but it will be useless if the room or building is not insulated - only when paired with thermal insulation works will a plate radiator show itself most effectively. In addition, the efficiency of a radiator is not a high temperature of the coolant, which is released into the air through pipes and plates, but maintaining a constant and comfortable temperature in the room throughout the entire time. Therefore, with the correct solution to the issue of the surface of such heating batteries, it is impossible to burn yourself - firstly, the temperature will not be critical, and secondly, the plates are covered with a metal casing.

If we approach the issue in principle, then plate heating radiators are a constructive version of convectors with a difference in the number of tubes and plates (there are fewer tubes, more plates).

The internal structure of the plate radiator

Similar to panel-type radiators, in plate devices there is a classification by the number of heat-exchange tubes and panels (plates), which are made by hot stamping and spot welding. Due to the tight connection, heat is given off not only from the surface of the plates, but also from the rest of the areas of the device - from pipes and even connecting seams and joints. The devices are marked in this way: if the radiator has one panel (plate on the body) and one heat exchanger, then it is marked as class "11". Three plates and two tubes - "32" class, etc.

If you want to buy and install a new radiator in a store or replace an old one, you will receive a mounting kit and instructions for assembly and fastening with the new model. Depending on the design of the device, its connection can be threaded or welded, depending on the input-output device of the coolant. In addition, you will need to connect a Mayevsky tap and a thermostat or two separate devices - the Mayevsky tap itself and a separate thermostat. It is not at all necessary to insert a thermostatic valve, but it will automatically regulate the temperature in a separate room by limiting the flow of coolant into the radiator coil. Recent models of plate batteries are often equipped with built-in thermostats and taps.

Plate heaters

Introduction

A plate heater is a bent or straight pipe for a water supply, with steel plates strung on it. A heat carrier moves through the pipe, and the plates significantly increase air convection. Structural simplicity determines their low cost. For aesthetics, the convector heater is closed with beautiful boxes made of thin white painted steel.

Steel plate radiators - general information

Steel plate heating devices in simple speech are called "" accordions ". The appearance of an accordion is made by plates strung on a pipe for a heat carrier.

A characteristic feature of this type of radiator is its high reliability. The plate radiator has no connections other than the inlet and outlet of the coolant. As a consequence, the heating device itself simply cannot flow, there is nowhere to push the heat carrier.

Due to the huge number of plates, and the direct movement of the heat carrier, the design heats up the radiator to a high temperature.To save it from touching, the key frame of the heater is covered with a decorative cover. Convection holes are provided in the upper cover of the casing.

Convector heaters have low thermal inertia, which means they can be controlled automatically, in other words, thermostats can be installed in systems with plate heaters.

Plate heaters form a rather powerful curtain of heat. This property of convector heaters makes it possible to use them in floor heating systems. True, the design of floor convection heaters differs from wall convector heaters, but the principle of heating is the same.

Cons of plate heating devices (convector heaters)

The convective type of heating devices does not make it possible to equally warm the room. The batteries are warmer than the opposite wall of the room.
Convector heater plates are a wonderful dust collector. It is difficult to clean them. Over a period of time, dust reduces their heat transfer.
The appearance of the plate heaters is not pleasing, although there are nice models.

Variations of plate heaters

As options, plate heating devices are used for floor heating (duct convectors) and plinth heating of the room.

Connecting convector heaters

There are two types of convector heaters for connection. This must be looked at at the time of purchase. The first type is a convector heater with side connection. The second type is a convector heater with bottom connection0. It is completed with a valve insert.

Heating capacity of plate heaters

The heat output of convector heaters depends on their length and the number of rows with plates. The height of all convector heaters is 200 mm.

Thus, the heat output of a convector heater in a "one line" 600 mm long is 347 W. It is also 3000m long and gives a heat output of 1730 W. A heater in 4 "strings" 3000 mm long gives a heat output of 4179 W, and it will give off 1393 W of heat with a length of 1000 mm.

The calculation of the heating device is carried out according to the standard calculation scheme for the sections of heating devices, taking into account all correction factors. Let me remind you how this is done. (read the publication: The simplest calculation of the heating system)

For 1 sq. meter of area with a ceiling of 3 meters, you need 100 watts of heat.
For a room of 16 sq. meters, a heating device of 1600 watts is required. This is under good conditions: one window, ceiling 3 meters, the room is not angular. If this is not the case at all, we use the correction factors:
Two windows k = 1.8: 1600 × 1.8 = 2880W;
Corner room k = 1.8: 2880 × 1.8 = 5184W;
Ceiling 2.65, k = 2.65 / 3.0 = 0.88: 5148W? 0.88 = 4547 W;
PVC window k = 0.8: 4547W x 3637 W.

A standard window has a width of 1400 mm, which means that under each window it is necessary to install 4-section plate heaters with a length of 1400 mm, with a heat output of 1950 W. The data are taken from the passport of Purmo heaters. That's all!

Specifically for Obotoplenii.ru

Determination of the thermal power of plate heating devices

The formula for determining the thermal power that a steel plate heating radiator can give, and a real example of calculating this parameter, are given below. To calculate the power of the device, it is enough to know the heat loss coefficient of the heated room, the area of the room and its total volume. The passport of any radiator indicates its design power at a hot water temperature in the system of 60 0 C. Also, the attached documentation contains recommendations on the heated area for a specific radiator model.

The heat output (power) of heating devices depends on the length of the body and the number of plates. The standard height of radiators is 200 mm, the number of plates varies.For example, the heat transfer for a radiator with one tube and a body length of 600 mm will be equal to ≈ 347 W. With an increase in length to 3000 mm, heat transfer will increase to 1730 W. But with the same body length (3000 mm) and an increase in tubes to 4 heat transfer there will already be 4179 W, and a pir with a body length of 1000 mm, four tubes with a coolant will give 1393 W of power. Therefore, which radiator is better to buy for a particular room is determined based on the following requirements:

For heating 1 m 2 of a room with a ceiling height of 3 m, you need to spend 100 W;
For a room with an area of 16 m 2, the radiator must have a thermal power of 1600 W, despite the fact that no more than one window is equipped in the room, the room is not corner and the ceiling has a height of no more than 3 m. For other initial conditions, correction factors Kp are introduced:
For two windows Kp = 1.8 / 1600 x 1.8 = 2880 W;
For a corner room Kp = 1.8 / 2880 x 1.8 = 5184 W;
For a ceiling with a height of 2.65 meters Kp = 2.65 / 3.0 = 0.88 / 5148 W x 0.88 = 4547 W;
For PVC windows Kp = 0.8 / 4547 W x 3637 W.

Choosing heating radiators for a private house which is better

When the construction work on the house is completed, the question arises of how to arrange the heating system so that the house is warm. The main component of the heating system is, of course, heating radiators. Their choice must be approached with particular seriousness, because the strength, durability and reliability of your heating system depends on it.
Consider the main advantages of the heating system of a private house:

Its work is carried out at low pressure, which favorably affects the operation;
In this system, there are no large hydro-shocks, this provides a wide range of radiator selection;
Observing the necessary technical conditions for the acid balance of water, the choice of radiators is very wide.

Taking into account the above, the choice of radiators should be carried out taking into account the maximum heat transfer coefficient and a good price-quality ratio. If you do not go into details, any type of radiator can be used in a private house. But knowing the benefits of one or the other still does not hurt.

For the manufacture of radiators, the following types of materials are used: cast iron, aluminum, metal (steel), bimetal.

Panel radiators

To get a panel radiator, you need to take two steel sheets, make them fins and weld them together. Connect the structure to the pipes of the heating system, start up the coolant and enjoy life.

There can be from one to three panels. They all come in various sizes. The design is lightweight. Such radiators can be controlled by automatics.
