How to choose a heating radiator
To forget the cold winter about warm woolen socks and terry bathrobes of the house, you can install not only the warm floor, but also change the batteries. We will tell you what radiators are better to choose for an apartment, and which for a private house.
For installation in stone houses it is better to buy panel instruments. They are worse thancing pressure jumps, designed for systems up to 10 bar, are not suitable for central heating, but ideal for low-rise homes, where the autonomous system is installed. These models are characterized by economical flow rate of the coolant, good heat transfer, in small sizes, are inexpensive.
For apartments, experts recommend choosing sectional or tubular models. These devices are characterized by good heat transfer, high anti-corrosion properties, withstand hydrowoods up to 35-60 bar. The inner surface of sections is usually covered with a special layer that protects the metal from destruction due to the effects of acids, chemical additives, which are often added to the central heating system.
What is better: steel, cast iron or bimetallic radiators? The speed of air heating, service life and reliability depends on the type and density of the metal.
Faster the air is heated Panel, tubular batteries made of steel . Minus - covered from within rust with air in contact when water is drained for the summer.
Cast iron models Heat, retain heat longer, they are not terrible hot water with increased acidity. When choosing, we should consider the weight and pay attention to the maximum pressure.
Bimetallic models - Universal solution for any system. In the manufacture of manufacturers usually combine steel with aluminum or copper with aluminum. Due to the design, they hold high pressure, well give warm, cooled longer than steel, but faster cast-iron batteries.
Manufacturers rating leaders usually consider Rifar, Raded, Sira, Royal Thermo . RADENA radiators are produced in Italy, are known for their quality, reliability.

Before starting to install a private home heating system, it is necessary to determine the type of radiators that will be installed to transmit heat energy. There are several varieties of such devices that differ in many parameters. When choosing radiators for heating, which is better for a private house, you can find out by comparing the main characteristics of the devices, and based on the information you received the right choice.
Choice for a private house
For the heating of a private house, you should not choose the cheapest models. In such devices, poor-quality materials may be used or their manufacturing was carried out with a violation of technological standards. Too expensive batteries for home heating also do not necessarily acquire, because in this case you can overpaid for the product more than 2 times.
If you navigate the price, then the most optimal option will be the acquisition of medium price level radiators in each category. The main separation of such products is carried out according to the material, of which they are made, and the type of transmission of thermal energy.
Heating radiators for a private house are made of metal. This material withstands significant loads and has good thermal conductivity. There are several alloys that can be used for the manufacture of heating sections.
Attention ! To select heating radiators, which will be ideal to approach specific operating conditions, it is necessary to familiarize themselves with the technical characteristics of each of them.
Heating elements made of aluminum have very good heat transfer rates. Such products are ideal for exploitation under conditions when significant fluctuations in the temperature of the coolant occur during the day. The efficiency of such devices is associated with the possibility of heat recovery of both convection method and in the form of infrared radiation. The undoubted advantages of aluminum batteries are also high aesthetics and low weight, in terms of cost such products are quite affordable.
The disadvantages of this type of products may be high demands on the quality of the coolant. Owners who are interested in which better establish heating radiators for a private house with a non-sufficiently prepared liquid for circulation in the heating system should be paid to more resistant to the negative effects of the device.
Cast iron elements have a very long period of heating, so such products are completely not suitable for installation in rooms, where the heating equipment is often disconnected. This disadvantage has a positive effect, because after stopping the boiler, such products will keep warm enough for a long time.
The disadvantages of such products include not too aesthetic appearance and high weight. The probability of destruction at high temperature differences can also be found to the merits. The main advantages of such products are relatively low cost and mechanical strength.
Bimetallic batteries combine the dignity of steel and aluminum products. In such products, the inner part is made of a black metal, which is relatively resistant to high pressure, increased acidity and the abrasiveness of the coolant. The outer shell is an aluminum shirt that perfectly removes heat from the fluid circulating over the inner tube.
Bimetallic heating elements are heavier than aluminum, but in comparison with cast iron products have a significantly smaller weight effect on the walls. Thanks to the advantage of the material of the outer shell, it is possible to make products of such forms that have high aesthetic characteristics.
Attention ! The disadvantages of bimetallic radiators are relatively big cost and the need to carry out installation work is very careful not to damage the aluminum shirt.
The advantage of steel radiators is primarily in high reliability. Such products are very simple in the manufacture. In compliance with all rules and rules of production, as well as if exploitation was carried out under appropriate conditions, steel elements can be used for decades. The cost of radiators of this type is small, which makes them very popular among domestic buyers.
Attention ! The disadvantage of steel structures is weak corrosion resistance, so the coolant must necessarily be properly prepared before the heating system.
Radiator heating devices can be made of various shapes and size, and also differ in the type of heat recoil.
The advantage of sectional products is that it is possible to accurately choose a product for power. In modern devices, such elements are connected by thread, so you can easily not only disassemble standard factory products into smaller, but also combine several separate elements into one heating device.
Due to the presence of a large number of compounds sectional radiators are able to withstand less pressure, but due to their versatility such products occupy the highest positions in the ratings of the best-selling devices for heating systems.
Tubular radiators are unsolved structures, but this deficiency is compensated by a variety of forms and sizes of such products presented in the market. There are such installations from a large number of pipe segments connected to the input and output manifiers. As a rule, tubular elements are made of steel, so they have the same technical and operational characteristics, as well as products made of ferrous metal.
The advantage of tubular radiators is the possibility of making products of very large sizes that can be installed in rooms with high ceilings.
By purchasing panel radiators, you should calculate the possibility of installing such products in advance. Such products do not have sections, therefore, to install the device, you need to know in advance the dimensions of the free space for mounting.
Panel heating products have modern design, high degree of heat transfer and easy to use. An important advantage of such structures is also a low cost, because the products are usually made from steel sheets.
Among the main drawbacks of panel radiators can be called instability to hydrowood and increased acidity of the coolant.
Plastic radiators are very efficient heating devices. In heaters of such a design, the heat transfer surface is increased due to the welding to the pipe, according to which the coolant is circulated, a large amount of thin steel plates. Due to the low inertia of heaters of this type, they can be used as the main sources of heat in the country or indoors, where the heating is not carried out in 24-hour mode.
Plate radiators have a very simple design, so during operation any breakdowns in the heating system are extremely rare. The cost of such products is small, because the production process is maximally automated and does not take much time.
Attention ! The disadvantage of lamellar radiators is a greater complexity during cleaning, because a large amount of dust is assembled between the subtlety metal plates.
Radiators for a wooden house
It is better to put a gas or electrocotel in the wooden house instead of stove heating, from which the heated coolant will be directed towards radiators. Restrictions on the type of radiator for housing from this material does not exist, but before putting heating, it is necessary to carefully calculate the number of sections.
Calculation of the number of sections
Knowing the area of heated premises and thermal power of the radiator section is easy to calculate the required number of sections. With proper insulation of the room for heating each m 2It is necessary about 100 watts. To obtain the total power value, the area in square meters is multiplied by 100, and the resulting value is divided into power indicators of 1 section.
Recommendations for choosing
The dignity of the private heating system is the absence of hydrowards, so products of any type can be used for mounting. It should only be remembered that aluminum products are very sensitive to increased acidity of the coolant, so if it is impossible to reduce this indicator, you will need to use devices in which the liquid does not directly contact with this metal or its alloys.
Heating radiators are modern and effective elements and, despite the relatively high cost, are able to give heat much more efficiently different homemade. In addition, such products have a presentable view, which allows them to use them even in a very expensive interior.
Heating Radiators: Select the appropriate option for a private house, installation technology
The radiator is the necessary link of the heating mechanism of a private dwelling or apartment. He is responsible for the room to be comfortable and warm. Therefore, when it is elected, it is necessary to take into account not only the cost and external execution, but also the specifications of a particular product. After all, if the characteristics declared the creator of the radiator will not be the same in fact, then the rapid wear of the device and its breakdown is simply inevitable.
In a private house, in contrast to high-rise buildings, an autonomous heating mechanism is installed, that is, a system that does not depend on the conventional boiler room in any way. For this reason, the temperature of the coolant, as well as the network pressure will be completely different.
When you choose the heating batteries that will be installed in a private house, a number of factors should be taken into account:
- In the buildings of this type, the pressure on the coolant, tanks and radiator pipes will be significantly smaller. In fact, the radiator batteries will not experience such loads, due to which any models can be selected, even with thin walls.
- In the construction of the type of pipes under consideration, the length of the pipes from the heat source to the radiator is small, if compared with multi-storey buildings. For this reason, thermal losses are practically zero, and the heat carrier will be stronger. That is, in a private house, you should install models that will withstand such temperatures.
- It is necessary to quite a little liquid to fill such a heating system. If you wish, you can add ethyl alcohol and antifreeze. So you can make protection for radiators and pipes if the boiler will not be turned on for a long time.
- Even the slightest possibility of the occurrence of so-called hydrowards is excluded. True, a problem, expressed in the freezing of water in the pipes, may appear in the houses of a private type. It will be the reason that the batteries can simply burst if a person before leaving forgot to drain the water from there.
In the choice of heating radiators for a private house, it should be repeated from the main parameter - the area you are going to sculpt. In the same cottages, the space requiring warmth will be greater, energy consumption will be the same. It is best to install such batteries that will allow high-quality warming at a minimum of thermal costs.
It should be said that the heating batteries are of different species. And here it is not so much about their form and sizes, how much about the material from which they are made. After all, it is no secret that various metals have different heat transfer indicators, due to which the efficiency of the batteries can vary significantly.
If we say specifically about the types, then there are radiators:
- from cast iron;
- from aluminum;
- of steel;
Now let's say about each type in more detail.
The models under consideration are installed in our homes over a hundred years. Today they are very in demand due to ensuring high-quality room heating. They were also among the most popular in the USSR.
If we talk about their advantages, then you should call:
- long operational period;
- Excellent thermal returns;
- High strength, as the batteries can easily withstand high pressure inside and easily transfer the mechanical impact;
- They work even with the poor quality of the coolant;
- have resistance to corrosion formation.
At the same time, cast iron models have a number of minuses:
- large sizes, which significantly complicates transportation, maintenance and installation;
- a small thermal conductivity due to the massiveness of the metal and the fact that its surface of the porridge;
- Batteries need systematic and constant care - painting and maintenance;
- The walls should be good attachments for their installation;
- occupy a large area.
In addition, cast-iron models are not too attractive appearance, which almost always distinguishes them from the interior not the best. Therefore, it is often necessary to put additional jewelry on such radiators.
If we talk about this type of radiators, they are divided into three categories:
- from sections;
- from pipes.
Steel panel batteries are also called convectors, because heat supply is carried out using the convection process. They usually form a rectangle form, which forms two welded panels. The coolant moves between them on special channels. A similar radiator has a small weight, small sizes, which makes it possible to heat up in a short time and maintain a good temperature.
If we talk about disadvantages, then the main problem is a bad resistance of mechanical damage and not too good pressure indicators. In addition, such models are very susceptible to corrosion.
According to the characteristics, steel batteries from sections are something similar to cast-iron, although it has a number of serious differences:
- Pressure inside here is at the level of 16 atmospheres;
- Due to the presence of welded connections, radiators have increased strength;
- Large operational period - up to 50 years.
This type of radiators is not very common, because their significant disadvantage is the high cost. Tubular steel batteries in their functionality are similar to sectional and panel radiators, but their price will be even higher. The main reason for this is that they have a rather pleasant appearance, which allows you to find a model under the interior. Yes, and on such batteries, it is extremely convenient to dry things that will be important for families where there are small children.
Aluminum refers to the category of metals, which are perfectly carried out. For this reason, such radiators can provide full-fledged heating of almost any room.
Their benefits are:
- Excellent characteristics of thermal returns;
- small dimensions;
- Good working type pressure, which fluctuates in the borders of 12-18 atmospheres;
- Small mass.
The coolant in the radiators of this type circulates very well, which allows to provide excellent heat transfer. Such circulation here is possible due to the presence of free tubes of the intercoletory type. In the market, such models are pretty wide.
The cost of aluminum batteries will depend on the manufacturer But in general, it is quite accessible due to the low price of aluminum itself. In addition, such models have an attractive appearance, which makes it possible to consider them not only as a heating device, but also as part of the interior of the room. Thanks to its strict and neat geometric forms, such a battery can easily fit into any interior.
But aluminum models have their own minuses:
- they are extremely sensitive to the quality of the coolant, due to which the installation of water filtering is required;
- Very susceptible to serious pressure drops, so it is necessary to constantly control its level;
- It is quite bad to oppose the formation of corrosion, even despite the presence of a protective coating on a polymer basis;
- have a small service life - no more than 15 years.
In addition, the positive return of such batteries is not always an advantage. Good work of such a battery drives warm air up, which accumulates at the ceiling, which can cause a sharp drop temperature. Therefore, before buying such batteries, the amount of heat required for the room should be calculated.
Aluminum batteries are divided into three categories that will differ from each other by device and opportunities:
- Sectionable condated. Their device makes it possible to replace the plates that have broken.
- Whole. Have a solid design and differ plasticity.
- Combined. They combine all the best of the two categories mentioned above. They are considered one of the best solutions for owners of their own homes. If you fully comply with the operating conditions, then such radiators will be able to stop 10-15 years and will really effectively warm the house when it's cold on the street.
As a rule, the inner part of such radiators is made of steel or copper, which makes it possible to ensure their good work and enhances safety. And the outer side is usually equipped with aluminum ribs. To date, bimetallic batteries are considered the best solution in this area. According to manufacturers, their batteries will be able to serve about 40 years. At the same time, they have a greater value, but still their characteristics provided them with excellent positions in the market. It is advisable to buy similar solutions in case the price of the price is not the main one. But they will definitely pay off the money and will work quite a long time.
Recently, the vacuum type of batteries has started to gain popularity. If you compare them with other types, they have a number of advantages. For example, they require a smaller amount of coolant, which will contact through the wall with a lithium-based specialist and boron having a boiling point of +35 degrees. Also, such radiators have excellent safety characteristics.
If you call other advantages, it should be noted:
- Reducing the coolant level for 80 percent mechanism;
- Reducing the use of coolant from the centralized heat supply mechanism tripled;
- If induction boilers are used, you can save up to 40 percent of electrical energy;
- carry out the installation of such batteries is quite simple even independently;
- In radiators, absolutely no corrosion, as well as air traffic jams;
- No need to use a powerful circulation pump unit due to low local resistance;
- High thermal returns.
Heating devices made of quartz - novelty in this segment. This type of batteries cannot be called high-tech, because it is an extremely simple option. Using the batteries of this type, it is possible to make an efficient, reliable and economical heating mechanism, which will maintain heat in winter. Quartz radiator will fit into any interior of the house.
Its design is simple and represents a monolithic slab, inside which the heating element is embedded, made of alloy chromium-leather alloy. The stove is made from a special system based on a quartz sand. The use of such sand is not accidental, because it can give a warmly warm, which has previously accumulated. Even if you turn off such a radiator from the heat network, it will long be warm, which will significantly reduce the consumption of electricity.
If we talk about the benefits of this type of batteries, then you should call:
- Efficiency. The small consumption of electrical energy is the main advantage of heating devices from quartz, because other solutions consume a significantly more electrical energy and the rest of their advantages are simply going to no, because the price of electricity is quite large.
- Substantial heat capacity. The quartz plate has quite serious thermal inertia. She heats up for a long time and slowly cools, as mentioned above.
- Durability. The heating element in this case does not contact the environment, which does not allow it to oxidize and significantly increases the service life.
- You can connect the thermostat, which allows you to obtain automatic control of the heating system.
- Pretty low cost, if compared with electric type water heaters or other heating devices.
- Fire safety. The temperature of this battery will not be more than 95 degrees, due to which the ignition of materials that are located next to the heater are completely excluded. This allows the installation of the device to be installed on almost any surface, including wood, plastic and plasterboard.
- Electrical safety. Such a battery does not create serious electrical accessories and can work smoothly almost throughout the season.
- Just installed. Quartz battery is attached to the wall using brackets.
- Do not need maintenance and do not require serious care. The only thing to do with such a battery is to wipe dust from it.
Popular manufacturers and reviews
In the segment of cast-iron models, the most famous manufacturers are Chinese Tokio and Konner companies. A good domestic model of such batteries will be MS-140.
If we talk about steel panel solutions, the products of Korado, Buderus and "Liday" are considered the highest quality. But tubular steel solutions are usually issued by foreign companies. Among them, Zehnder, Arbonia and Delonghi are allocated.
Aluminum batteries are issued both foreign and domestic companies. Among them are such well-known manufacturers like Global, Ferroli and Riffar.
Bimetallic models are produced by both foreign and domestic firms. If we talk about domestic, then the brand "heat transfer," and if there are products of the brands of Polywarm, Sira, Royal Thermo Vittoria and the German company Kermi. When choosing ceramic batteries, it is worth paying attention to the products of the brand "Teplako".
Now let's talk about the experience of using various types of batteries by users and their reviews. It is logical, because manufacturers often declare one, and in practice we get completely different. If we talk about cast iron radiators, then users note that even beautiful solutions are not easy to install and they have a rather serious mass. In addition, it is often necessary to install additional brackets.
We will say a few aluminum radiators in more detail by reading the reviews of user batteries of various brands. If we talk about Sira aluminum batteries, then users note that they warmly warm and have an excellent appearance. Users also celebrate good heat transfer models. But many are not very satisfied with a considerable value of solutions from this company. Also, users are praising such batteries from Global and note that they warmly warm in combination with the boiler and have an excellent appearance. The same applies to solutions from Rifar.
Bimetallic batteries users also do not bypassed attention and in general respond about them very flattering. For example, Rifar batteries look great in different interiors, quite durable and can withstand large pressure, as well as high heat carrier temperature. In general, it is impossible to make some clear rating of radiators, because they all have a number of their positive and negative parties. You can clearly note one thing - in any case, it should be individually determined which batteries in a particular private building will be the best solution.
What better to choose?
If there is a desire to choose an economical option for a country wooden private structure, it is best to install high-quality aluminum radiators. Such solutions have everything you need: modern design, ease, affordable price, and their negative sides are not so serious in the conditions of the autonomous heating mechanism of the private house.
If money is not such a serious question, then it will be an excellent solution to the installation of cross-type bimetallic batteries, especially if we are talking about a copper-aluminum combination. And if there are small children in the house, then to protect them and other households, you can stop your choice on convection options, completed with certain protection options. If you need to hide radiators, then you can use outdoor convection solutions.
If the house has a stove with water contour, the easiest fuel boiler or your home is equipped with gas heating, you can use cast-iron batteries tested by time. Despite the fact that their choice entails difficulties with the installation and mass, they at the same time allow you to significantly smooth out temperature fluctuations and to store heat for a longer. Yes, and now you can easily choose options with a pleasant design, if they are on your pocket.
Heating of radiator type in his own home - the key to comfort and coziness in the fall and winter. Well, when such a mechanism has already been connected to the heating mechanism of centralized type. If there is no such thing, there is a need to apply an autonomous heating. If we are talking about making the installation of the heating system with your own hands correctly, it should be said that the most important element will be the choice of options for connecting radiators in the house of your own construction.
A number of people and are not suspected that it plays a very significant role in the heat transfer device, circulation inside the heat carrier and the speed of hot water movement. The above as a whole will have a significant impact on the efficiency of the entire mechanism.
The first thing you need to figure it out, this is a pipe layout. This can be called an important point, because the tenants of their own houses at the stage of their construction rarely when they can clearly and correctly calculate the costs that will be made on the formation of the heating system, because it is necessary to make savings on various kinds of materials. Typically, the method of connecting pipes can be either one or two-pipe. The first option is economical, in which a pipe is carried out from the heating boiler on the floor, which comes through all the walls and rooms and which returns to the boiler. Radiators should be installed on top of it, and the connection will be carried out using nozzles from the bottom. At the same time, hot water goes in the pipes, completely filling the batteries. Then the water is lowered and through another nozzle enters the pipe. In fact, there is a serial connection of the radiators due to the lower connection. But there is a minus, because at the end of such a connection in all subsequent radiators the temperature of the thermal carrier will be lower.
You can solve this moment in two ways:
- Connect to the entire mechanism a special circulation pump, allowing uniformly in all heating devices to distribute hot water;
- Connect additional batteries in the latest rooms, which will increase the heat transfer area to the maximum.
If we talk about a two-pipe layout, then for your own house, a similar connection system will be more efficient. But at the same time, expenses will be significant due to the fact that it is necessary to carry out the divorce of two pipes. One must be put to supply hot water, and the second to connect to its removal.
When it all became clear with this question, it should be focused on the joining the heating batteries. The most common side will be. To make it, you should display pipes on the side of the wall and connect to two batteries - on top and bottom. From above, a pipe feeding the heat carrier is usually connected, and from the bottom - output. Effective will also connect a diagonal type. To perform it, it follows to start to the pipe at the top to connect the pipe feeding the heat carrier, and to the bottom located on the other side - the return. It turns out that the thermal carrier will be transported diagonally inside the radiator. The effectiveness of such a mechanism will depend on how the fluid is distributed in the radiator. Rarely when several battery sections can be cold. This happens only in cases where the ability of the skipping or the head is weak.
Note that the connection of the radiator from below can be not only in one-tube, but also two-pipe versions. But such a system is considered extremely ineffective. In this case, it will still be necessary to establish the circulation pump, which will significantly increase the cost of creating a heating mechanism and will create electricity costs that are needed for the pump operation. If we talk about what you do not need to do, then this is not to replace the flow of water in the return. As a rule, the presence of this problem shows debugging.
When installing decorative screens, the visibility of the thermostat is overlap, which is not necessary. Batteries will be basked for a long time. At the same time, it is impossible to mount the head of the thermostat in a vertical position, because it will lead to its unstable work.
Installation of heating radiators with their own hands in its own house is associated with a number of moments who do not say that this is an easy process. His complexity consists also in the fact that in each individual case it is necessary to selection batteries for one or another structure, as well as to know how in a private house, which is already built, pass pipes. Also an equally important fact will be an understanding of the needs for heating and carrying out all necessary calculations.
In addition, we should not forget that there are various connection schemes and something that may be inefficient in one house, in another will be an excellent solution. If you have decided to make the installation of heating radiators yourself, then it is necessary to thoroughly examine theoretical moments, as well as if possible, at least consult with a specialist who will prompt that during the installation of radiators and the heating system as a whole should be paid particularly close attention.
On how to choose the right heating radiator, see the next video.
The choice of heating devices for the water system always remains the prerogative of the homeowner, even when the installation is performed by the wage masters. But choose the batteries on the advice of sellers or the reviews of Internet users are not easy - the first often do not understand the topic and repeat the advertising slogans, the second "praise their swamp", which is quite explained. To find out which heating radiators are better to choose for an apartment or a private house, we offer to use a simple and understandable algorithm.
Instructions for the choice of batteries - a simplified approach
Before buying or ordering new heating radiators, it is necessary to explore the catalogs of large online stores. This will determine the order of prices and see the existing types of batteries. All water heating convection devices are divided into 4 groups:
- aluminum sectional;
- bimetallic - sectional and monolithic;
- Steel - panel and tubular.
Lyrical digression. You can read reviews and articles on resources that publish ratings of products of various brands. But the good use does not bring information - endless disputes are on the forums and fake feeds are written, and ratings are often compiled on top 10 manufacturers from the first search pages.
To select the power of heating radiators, it is necessary to pre-calculate the amount of heat consumed on the heating of each room. Methods for calculating - in the area, volume or thermal loss of the building - published by a separate article. How to choose the batteries:
- Fuck the cost of a future purchase, let's follow more expensive and too cheap heater options.
- Select models that have liked in appearance, form and color, well fit into the home interior. Pay attention to the height of the batteries so that they are placed in the niche.
- If you live in the apartment of a high-rise home (9 floors or more), open the page with the technical characteristics of the selected radiators and find out the maximum working pressure of the water - the device must withstand at least 12 bar.
- For the hosts of private cottages, the pressure parameter is not of interest - models are suitable with any characteristics. If the house is heated with a wood or coal boiler, it is worth checking the maximum coolant temperature - the indicator above, the better.
- Ask, what connectivity methods are provided by manufacturers of selected batteries. The lower eyeliner allows you to better hide the heating highway, with a lateral version of the pipe you will have to be muted in the wall or leave in front.
- Find out the weight of the product and the installation method - outdoor or wall. Find out whether the radiator is equipped with installation brackets and huts, otherwise additional costs will occur. Radiator valves and crane Maevsky is usually purchased separately.
- Make the final selection of the model and determine the size of the radiators by power. How the actual heat transfer is calculated 1 sections (panels), we will talk at the end of this instruction.
Please note - we did not mention the materials of the manufacture and types of instruments. In fact, this factor does not play a big role. Modern radiators differ little by technical parameters, it is important only the heat transfer indicator. The lower threshold of working pressure is only in high-rise buildings.
Next, we consider the device and characteristics of various batteries, compare their advantages and disadvantages. But first dispel the popular myths invented by advertisers.
Myths about heating radiators
In order to promote one or another products, three common non-residents were invented about the heating devices made from various materials:
- Heatthilling of aluminum radiators is significantly higher than steel and cast-iron;
- Radiators made of cast iron are massive, so it is warm and cooled for a long time, allegedly store heat;
- In the central heating network, hydroudars and pressure occur, which only bimetallic heaters are withstanding.
Note. The main well-established myths are listed here, we will tell about the other in the process of describing radiators.
Compared to ferrous metals - steel and cast iron - aluminum carries out heat much better. I confirm the numbers: the coefficient of thermal conductivity λ aluminum products - 209 W / (M • ° C), steel - 47 W / (M • ° C), pig-iron - only 42 W / (M • ° C). In what snag: heating devices are manufactured not made of pure aluminum, but the alloy of the AK12 group - silumin, where 11-13% of silicon and other impurities listed above are present in the table.
The purpose of the additive of silicon is to increase the strength and corrosion resistance of the alloy. The physical properties of silumin others, thermal conductivity noticeably below - 168 W / (M • ° C). Given the thickness of the walls of the batteries of 4-5 mm, the difference in the heat transfer of aluminum and iron devices in practice is invisible. Put in the room 2 of such radiator the same power - you will not be able to determine which it works more efficiently.
The best heat conductor is copper. It makes lamellar plinth heaters and copper-aluminum water convectors.
Stumbling stone - copper prices. The right photo shows the heat heater worth 70 y. e., Dimensions - 400 x 400 x 90 mm, thermal stream - only 430 W.
The following factors strongly affect the transfer of heat energy from any metal battery:
- temperature and coolant temperature;
- The surface area of the device;
- Delta temperature between air air and water in the pipes.
Reference. The difference between the average temperature of the coolant and the heated air is called the temperature pressure (DT). The value is subsequently useful when calculating the power of the instruments.
The remaining myths will dispel the items:
- When heating / cooling, the massiveness of the cast iron does not play roles, since its heat capacity is 9 times lower than being inside the water (0.54 kJ / kg • ° C against 4.18 kJ / kg • ° C). Therefore, the cast-iron battery will cool at the same time with the coolant, no longer. Silumin and steel are faster, since they can accommodate a much smaller volume of water.
- Hydraulic blows inside centralized heat supply networks simply does not happen. Maximum pressure in working mode - 10 bar, test - 12 bar. Modern aluminum devices calmly withstand such a pressure.
Construction and advantages of aluminum devices
The radiators of this type are manufactured by molding under pressure or extrusion. The finished product is a vertical single section or a whole unintellular battery (both varieties produces a well-known company Rifar). Of the individual sections, the heater of the required power is gaining, the method of compound is a threaded nipple with a gasket.
Inside the silicon radiator section, shown in the section in the photo, 2 horizontal collectors are pretended, between them - a vertical connecting channel of oval cross section. The outer heat exchange part is convection ribs covered with heat-resistant powder paint. The form of fins and the number of plates determines the manufacturer.
Reference. The height of the battery is considered to be between the centers of horizontal collectors. Aluminum products are offered in 3 standard versions - 35, 50 and 80 cm. The allowable pressure in radiators - 14 ... 16 bar, heat transfer sections with an inter-axis distance of 500 mm - about 190 W according to the Italian brand Global.
Advantages of aluminum alloy batteries:
- low weight;
- attractive appearance;
- Effective heat transfer contributes to a large surface area;
- Small capacity for water - 0.2 ... 1 l, depending on the size;
- The relatively low price is 7 ... 10 y. e. For a section, Chinese models - from 5 y. e.
Low corrosion resistance is considered a lack of aluminum, although in practice heaters serve in central heating apartments for 20 years. Approval should be attributed to private homes, where too rigid water is used as a coolant, saturated with magnesium and calcium salts.
The second minus is inherent in any sectional batteries - when pouring the non-freezing coolant at the joints, leaks arise. One-piece modifications, for example, "Riffar Monolith", do not have such problems.
Pros and Cons Bimetal
How easy it is to guess the name, heating devices are made of 2 metals - silumin and steel. Externally batteries are indistinguishable from aluminum sections, but inside collectors and vertical channels iron tubes, welded with each other, are embedded. Steel frame is designed to solve 2 tasks:
- protection of the synthetic part from the chemical effects of the coolant in old centralized systems;
- Improving the reliability of the radiator by increasing the operating pressure threshold to 20 ... 30 atm.
For reference. There are bimetallic models with double vertical channels made for the improvement of water duct and heat exchange. An example is a line of unsolved batteries Rifar Supremo shown below in the photo.
For the remaining technical characteristics, the bimetall differs little from aluminum - the power of 1 section, weight and capacity is almost the same. The operational advantages of radiators are also preserved, but a couple of flaws appear:
- The price of the batteries is higher by 30-50%, for example, the original bimetallic section of the company Global Style Plus with an inter-axle interval of 500 mm costs about 15 y. e. (970 rubles);
- Because of the different coefficients of thermal expansion of silumin and steel tube core can burst on welded joints, repair and close the leakage - unreal.
An important addition. In the sale sometimes there are defective bimetallic radiators with steel tubes, sealed only inside collectors. The vertical section of the section remains unprotected.
Features of cast iron "accordion"
The device of batteries made by casting from gray cast iron, familiar to most homeowners. Like an aluminum "fellow", the heater is recruited from individual sections twisted by nipples through the gaskets (a long end key is needed).
The cast iron batteries present in the market are conventionally divided into 2 groups:
- Products of the Soviet MC-140 brand, the inter-axis interval standard - 300 and 500 mm.
- Designer models, cast in modern style, retro and so on. Distance between traffic jams - arbitrary.
The inexpensive "accordions" of the MS series is significantly losing with any radiators in appearance, are used mainly in industrial premises. The heat transfer section 50 cm is 160 W, the operating pressure is up to 9 bar, the contained volume of water is 1.45 liters. Cost - from 6 y. e. (420 rubles).
Beautiful designer batteries from different brands are very different in dimensions, power and other parameters. The table shows the characteristics and prices of decorative heaters from Czech, Turkish and Russian brands (excluding the value of decorative shut-off valves).
Note. The numbers after the names of the products denote the mid-scene distance and the thickness of the heater in millimeters.
Cast-iron "accordions" are reliable in work, durable and completely not afraid of corrosion. In appearance, retroradiators confidently occupy the first position among all heating devices. Now reveal the negative points:
- The transient price of design sections is noticeable on the table;
- cast iron fragile, splits from shock loads;
- solid product weight;
- The battery accommodates 2-4 times more coolant than other types of radiators.
The so-called inertness of cast-iron sections is explained just an increased capacity. Two liters of water cools significantly longer than 0.2-0.6 l in the aluminum section. Especially severe modifications, for example, Retro Style Anerli, are produced in the outdoor version and are equipped with legs.
Advantages of steel radiators
Manufacturers offer 2 versions of iron batteries:
- panel - flat and profile;
- Vertical tubular (sectional).
Comment. Both species are produced in the design vertical version (see above in the photo). Known in the post-Soviet space brands: Kermi, Korado, Purmo, Arbonia and others.
Warning panels are welded from stamped steel plates with a thickness of 1.2 ... 1.5 mm. Side or bottom of the radiator are installed fittings for attachment. A convective ebony is fastened between the panels. Batteries are divided into types depending on the number of heating panels and profile finments, as shown in the table.
Operational indicators of panel heaters (taken according to the German radiator "Kermi" Type 22, installation size 100 x 50 cm):
- permissible pressure - up to 10 bar;
- Thermal capacity of 1550 W at water temperature at 75 ° C, the return - 65 ° C;
- The volume of the coolant is 5.4 l;
- The mass of units is 28 kg, the price is 95 y. e. (6300 rubles.).
The characteristics of tubular radiators are not too different from the panel. If you take the Arbonia 3050/22 two-row device, comparable to the size with the "Kermi" option (500 x 1014 mm), we obtain the power of 1481 W with the same working pressure and weight of 25.9 kg. Only the price of the product is another - 430 y. e.
As we consider the options affordable options, we list the pluses of panel batteries:
- Steel panels are the most fiscal option among all radiators;
- resistance to chemical corrosion;
- acceptable design and appearance;
- One-piece design allows you to pour antifreeze to the system and not be afraid of leaks;
- The ability to pick up power without resizing - by adding heating panels and ribs (from 1 to type 10 to 3 pcs. Type 33).
The disadvantage of radiators is considered a low operational pressure threshold - 6 ... 10 bar. We will not refute this, but we will offer to watch the video of our expert, where the inexpensive steel panel is pumped up with the crimping pump to break the weld (pressure over 20 bar):
How to find out real heat transfer
Selecting the heating devices in the online store, it is difficult to find real parameters of the panel power or one section. Sellers are more profitable to declare the maximum heat transfer, which is practically unattainable when heating a country cottage or apartment. According to the passport, the water temperature in the supply pipe must reach 90 degrees, reverse - 70 ° C, room air - 20 ° C.
Reference. In modern household heat generators, the heating temperature is limited at 80 ... 85 degrees.
Selection sections on heat transfer We recommend doing this:
- Open the official site of the manufacturer of your favorite batteries and download instructions instructions. It is precisely indicated in it, with what the temperature pressure of the DT radiator gives the nominal amount of heat. Focus on 70/50 ° C mode.
- If the instruction is missing, take the manufacturer data for the truth and multiply the heat transfer to the boost rate 1.5-1.8. Having made a one-hour stock, you definitely do not lose.
- The last paranolars of a single-tube system are chosen with a double reserve, as they get the smallest amount of thermal energy.
The most accurate method of selection is the calculation of heat transfer according to the specified temperature presumpture. The calculation algorithm is described in detail in the appropriate material.
Conclusions and recommendations
We hope the preceding description helped you to figure out which heating batteries are better for apartments for the price and technical indicators. Finally, we will give several practical advice:
- Use the instructions given at the beginning of this publication. Choose radiators that are more suitable for design and budget.
- The working pressure head of the coolant matters only for apartments of high-rise houses, the pressure of over 10 bar will withstand only bimetallic and aluminum batteries. For cottages and private cottages, any water heating devices are suitable.
- With a limited budget, boldly buy steel panels - they do not inferior to other heaters or convectors.
- Under the sampling system you need to take radiators with a large cross section of internal channels. Steel stamped heaters are better not to put, only tubular.
- By the price - quality and set of operating parameters, the first place occupies sectional batteries from lightweight aluminum alloy.
- Behind the bimetal is worth paying when there is no confidence in the parameters of the coolant - the pressure is unknown, rigid water is used.
- Try not to acquire frankly cheap radiators, blinded from an unknown material in the PRC. They will warm them, but for sure not long.
Conclusion regarding cast iron. The heating radiators of the old type MS-90 and MS-140 are cheap, but look non-zero. Beautifully designed models are incredibly road, and therefore inaccessible to ordinary homeowners. The cast iron becomes a rarity, and the outdated "accordions" of the MS series go into the past.
If the budget allows you to put design heaters, choose every battery in dimensions. In a narrow wall niche, it is better to place a vertical steel heating radiator, under the windows - stylish cast iron products. Heavy floor versions are desirable additionally to mount to the wall with a pair of brackets.
When developing a project of an autonomous system for the heating of a private house, you must decide on the choice of batteries. The efficiency and efficiency of the heating system depends on their parameters, the level of comfort in the residential premises of the country house or country cottage. To determine which heating radiators are best suitable for a private house, it is necessary to compare their operational qualities, reliability and cost.
Radiator heating in a private house
When choosing a heating system for cottages or at home, you need to take into account the cost of installation, ease of operation and efficiency. For a brick, block, frame and wooden house, water heating is equally well suited. This option is cheaper to use compared to the installation of heating electrical equipment and more efficiently a conventional stove fuel for which coal or firewood serve.
The radiator heating system for a country house or giving has an advantage over water outdoor heating, since the installation of the pipeline and radiators is easier and faster than to lay the outline and equip the screed.
From central heating, autonomous is different:
- low operating pressure;
- lack of risk of hydrowarders;
- the ability to adjust the temperature of the coolant, to establish a maximum allowable;
- the ability to adjust the acid balance of the coolant;
At the design stage of the autonomous system, determine which heating batteries and pipes are used for installation. It depends on its functionality, efficiency and durability.
Varieties of heating batteries
To choose to heating a private house radiators with best operational qualities, it is necessary to understand the virtues and disadvantages of heating batteries that the market offers. Consider each type of heating instruments follows from the properties of material and design features.
Radiators differ :
- by manufacturing material (steel, aluminum, cast iron, bimetallic);
- By design (sectional and solid):
- According to the principle of heat transfer (radiating thermal energy, convection and combined).
Among the heating radiators for a private house, steel models made of steady demand. The list of advantages includes:
- relatively low weight, which simplifies installation;
- Quick heating and cooling - allows you to flexibly adjust the temperature in the room when using the thermostat, saving fuel;
- rather long operational period;
- A wide selection of models with different functionality and appearance.
The disadvantages of heat heating devices include:
- The tendency to corrosion - such batteries are calculated on the installation in the heating system of the closed type as the free penetration of air into the coolant accelerates the process of metal destruction;
- The tendency to the upstream due to the rough inner surface - the regular flushing of the system is required;
- Restrictions on the characteristics of the coolant - adding alkaline reagents should be avoided.
To understand what steel heating device to choose, consider in detail every variety. Manufacturers offer sectional, tubular, panel and convect steel heating appliances.
The battery consists of individual units, the number of which can be changed. This is a serious advantage of heating devices of this type. If the thermal calculation is incorrect and the radiator power is not enough, additional sections are added. If the house has been insulated and the need for powerful radiators disappeared, it is enough to remove unnecessary sections to reduce the energy consumption. The advantages of sectional models also include a stylish design that will fit into any interior. The disadvantage is considered a large number of joints, due to which the risk of depressurization of the battery increases.
They are distinguished by the original appearance, convenient for drying things. Reliable and durable due to the absence of joints - the radiator is a one-piece design. At the same time, it is important to choose the proper heating device by power, as it will not be possible to correct this parameter.
Panel-type heating radiators are characterized by a stylish concise design. Unlike tubular and sectional batteries, panel models, equipped with convective fins, heat the air indoors faster - the formation of a flow of heated air is added to thermal radiation. The possibility of creating a thermal curtain makes panel radiators in demand for installation in rooms with a large glazing area. Panel radiators, like tubular, are solid. Models of this type can not only be mounted on the wall, but also installed on the floor.
Water convectors consist of steel pipes on which numerous metal plates set by the edge are mounted. From above, the heating device is closed with a stylish metal casing. There are models embedded in the floor. The gaps between the plates contribute to the formation of the flow of heated air. Convector radiators are recommended to put along panoramic glazing, in the winter garden, indoors with high ceilings. Due to the natural convection, the room warms up faster than thermal radiation. Solving which radiators are better, it should be noted that for a system with water convectors, a smaller coolant is required compared to the use of other types of radiators. The disadvantages of convectable radiators include high cost. In addition, during the operation of such a battery, the air flows constantly raise dust, which falls into human respiratory organs.
Considering different types of radiators, it is impossible to bypass the classic option - the cast iron batteries. Until now, working specimens installed before the revolution have been preserved in old houses. In the houses of the Soviet buildings are massively used cast iron radiators of the serial sample.
Benefits include durability and resistance to corrosion, high heat transfer, the ability to install additional sections. The list of disadvantages includes a tendency to the upstream - with the heat transfer of such batteries, it falls, since the free space is narrowed inside the case. Unlike modern heating devices, cast-iron batteries are required to regularly paint. Also, the disadvantages include a lot of weight gaining transportation and installation.
Before choosing a cast-iron battery for a private house, you need to pay attention to its high thermal inertia. It slowly heats up and cools, which makes it impossible to quickly adjust the microclimate in the room.
Today in private houses, radiators from cast iron are installed if they want to emphasize the individual image. Manufacturers offer original outdoor models, decorated with an artistic casting that perfectly complement the interior in the classic style.
Solving which heating devices are better to choose for a private home, pay attention to aluminum models. Such radiators enjoy the growing demand in private developers due to the low weight and ease of installation, attractive appearance, the ability to add and remove the sections. The cost of the product depends on the manufacturer. Domestic products are maximally available for the price, this is a budgetary dacha option. In a country house, put imported products, it is more reliable, but it is more expensive.
- may leak due to the presence of threaded connections;
- Aluminum is demanding for the acidity of the coolant - the use of liquid with unsuitable parameters displays the heating devices;
- Due to the increased heat transfer, it can be bad to warm up the lower part of the room - the heated air quickly goes up and the floor remains cold.
But despite this, it is reasonable to choose a radiator from aluminum for a private house - the metal is quickly heated and cools, allowing to quickly change the level of heating of the room in accordance with weather conditions and microclimate requirements. In this regard, the battery from aluminum is the most practical.
Such heating devices combine the benefits of steel and aluminum models. The inner surface of a durable iron alloy is undemanding to the characteristics of the coolant and ensures the structural strength of the battery. For external aluminum casing, good heat transfer is characterized, due to which the radiator effectively warms the room.
The bimetallic radiator is designed for high working and crimping pressure, which makes it an optimal choice for installation in an apartment connected to the central heat supply network.
Given the high cost of high-quality bimetallic models, in private heating houses it is better to use a budget option designed to work in the autonomous system.
Battery Power Calculation Principles
To select heating radiators for a country or private home, it is required to perform calculations based on the fact that for heating of one kV. The living area requires approximately 95-125 kW. To warm up the room with averaged parameters (one window, one door, the ceiling height is up to 3 meters) It is necessary to heat the coolant to 70 ° C.
If the real parameters differ from the specified, it is necessary to make amendments. For example, with ceiling heights, more than 3 meters need to increase the calculated battery power at as many times as the actual height is exceeding conditional. With low ceilings, recalculation is conducted in the opposite direction.
Reducing the temperature of the coolant for every 10 ° C relative to the specified averaged mark forces it to increase the calculated power of heating devices by 15-20%. If the room is an angular and two windows in it, the average calculation capacity of the batteries is 1.5 times.
The heat transfer of radiators largely depends on the circuit of their connection. The averaged calculation is based on the fact that the heated coolant is fed to the upper side input, and the reverse is connected to the bottom input diagonally. Other connection options are less efficient and reduced by the heat transfer of batteries by 5-10%.
Note! The number of sections in the radiator models of this type should not exceed 10 pieces - further extension will not help increase power, as the coolant will not be able to fully warm the battery.
Calculate the parameters of the radiator
Particularly closely close to the selection of panel and tubular batteries. Manufacturers include in the product line of the model of the same power, but with different geometric parameters. When choosing, the features of the installation site are taken into account - the height from the floor to the windowsill, the length of the wall in the elongated room, etc.
Homeowners choosing heating devices and wishing to acquire the best options for a spent price, stop their choice on steel or aluminum models. The cost of the most reliable, imported bimetallic radiator is exormably high, and cast-iron batteries have a lot of serious minuses. According to statistics, those who think about which radiators to choose into a private house or in the country, stop on aluminum sectional or steel panel models based on the price and practical ratio.
