Now residents of the multi-storey sector are massively replacing worn-out heating radiators with new and more advanced devices, which the domestic market is full of. heating equipment... Since 1994, in our country, they are in great demand bimetallic radiators from the well-known Italian company"GLOBAL DI FARDELLI OTTORINO and C". They receive positive reviews from Russian consumers due to the high mechanical strength, resistance to water hammer, temperature surges, corrosion. To based on preliminary calculation choose a suitable model from the Global series, it is advisable to study specifications battery you like, find out the average cost, find reviews on the forums.

Externally, the bimetal practically does not differ from the long-known aluminum analogs. At the same time, bimetallic radiators weigh much more due to the use of a strong inner steel shell, which is filled with an aluminum alloy on top, which provides good heat transfer. High reliability of Global radiators is achieved due to the fact that horizontal and vertical pipe collectors are welded together and form a single whole. Here are the advantages of this technical solution:

• bimetallic radiators withstand an operating pressure of 30-40 atmospheres (this is also facilitated by hermetic gaskets);
• it is possible to use antifreeze (acid-base index 6.5-9.5);
• heat transfer of a section with a center-to-center distance of 500 mm - from 170 to 190 W.

The models have two standard sizes, differing in the level of the upper and lower collectors. The difference between the levels is called the center distance: it is 350 or 500 mm.

The Global line includes bimetallic radiators belonging to four main series:

1. Global Style - flat top, universal in use, suitable for any window sill;

2. Global Style Plus - have increased dimensions and power;

3. Global Sfera - the upper part of the spherical shape;

4. Global Style Extra - an improved modification of the Style series, which has classic design and designed for a pressure of 52 atm.

The table shows the main characteristics of the popular models of bimetallic radiators from Global (the dimensions of one section are indicated):

Model	Center distance, mm	Dimensions, mm	Coolant volume, dm3	Power, W	Weight, kg
Global Style 350	350	80x80x425	0,18	125	1,6
Global Style Plus 500	500	80x95x575	0,2	185	2,1
Global Style Extra 500	500	80x80x566	0,2	166	1,85
Global Sfera 500	500	80x80x568	0,16	165	1,77

What should the buyer take into account?

In an effort to buy more profitable bimetallic heating batteries, you should know that according to the combination of materials, they are of two types

• "Full bimetal" - it has made of steel inlet and outlet collectors, as well as a vertical connecting tube. The coolant comes into contact only with the steel shell.
• Semi-metallic - in them only vertical intra-section pipes are steel. Wherein aluminum tubes collectors in contact with water can be destroyed due to electrogalvanic corrosion.

All Global bimetallic radiators are based on a steel frame that completely occupies the entire inner space... The upper aluminum body does not come into contact with the coolant, thus increasing durability (and price) heater... After the issue has been resolved in favor of bimetallic radiators, the choice should be continued according to other criteria and the characteristics of different models should be compared.

1. Heat transfer. Thanks to the specially designed ribbed surface, the aluminum shell of the radiators gives off heat well and distributes it, significantly outperforming aluminum models. The greater the center-to-center distance, the higher the heat transfer of the battery. A review of the Global series shows that Style Plus are the most powerful: heat transfer is 10% higher than that of their Global Style counterparts with the same center distance.

2. Number of sections. Owners country cottages first, you need to perform a thorough calculation of heat loss through all external structures (walls, ceilings, floors, doors, windows). For housing in standard high-rise buildings, you can carry out a simplified heat engineering calculation or use an online calculator. If a large-panel house is located in middle lane, then the number of sections for each room is calculated according to the following scheme:

• determine the area of ​​the room;
• the result is multiplied by 100 W (average specific heat transfer rate);
• the product is divided by the nameplate value of the thermal power of one section.

If you decide to choose a Global Style radiator model with a center distance of 500 mm, the number of sections is found by dividing the area of ​​the room by two. For example, a 10-section battery is sufficient to heat a room with an area of ​​20 m. To provide a power reserve, during the calculation, refinement coefficients are used, depending on the number and orientation of windows, the presence of 2 external walls.

3. Design and dimensions. If the niche in the wall is deep and the window sills are large, it is better to buy a model from the Plus line: its depth is 15 mm deeper than that of Style, there are additional ribs on the sides, higher heat transfer. Sfera modular elements are elegantly rounded and shallow. Flat batteries blend in with any décor and save space.

The characteristics are selected in such a way that Global (full bimetal) are ideal option for installation in houses with central heating. However, there are reviews that for the normal performance of functions before buying, you should find out the parameters of the coolant in the network: if the acidity is higher than 9.5, then you will have to set cast iron batteries or look for models with a stainless steel frame.

User opinions

“Almost 6 years ago, during the renovation of the apartment, we decided to change the batteries. Our acquaintance plumber prompted us to buy the Global Style plus 500 model. They have not been disappointed in the choice so far - the stylish pleases appearance, compact dimensions. But, of course, the main advantage of Global is its excellent thermal performance. At full power, sometimes we turn on the radiator that heats the room with the loggia. The rest of the devices work half-heartedly, with the help of thermostats we reduce the heat. "

Ekaterina Guryeva, Moscow.

“I have heard for a long time about Italian radiators manufactured by Global good feedback, but fully appreciated the bimetal only after installation in own apartment(before that we had Chinese batteries). The difference is tangible: Global heats up instantly, quickly distributes heat throughout the room, and dries less air. This winter in our corner apartment This is the first time we did not turn on the electric radiator: Global Style coped with the heating perfectly. "

Andrey, Moscow region.

“As a plumber, I will say a few words about heating radiators manufactured by Global. These batteries do not cause problems during installation: they mounted them on the wall, screwed them on by the Americans - and that's it. The mounting kit always contains a special nipple that allows you to quickly connect batteries to the system. Clients do not complain about full bimetal: usually such radiators work reliably. And the manufacturer gives a 5-year warranty. The only drawback is the heavy weight due to the steel frame. "

Eugene, Yekaterinburg.

“To keep the apartment warm, you need to choose the right number of sections for bimetallic radiators. The model you named Global thermal power one section 120 W at average temperature water in the central system + 75 °. Based on this, a 14-section heating radiator is needed for a 17 m2 room. I advise you to put taps at the inlet and outlet: one - to reduce the flow rate of the coolant (and the temperature in the room), the other - to service the batteries (flush them once every 3-4 years). "

Peter, Magnitogorsk.

“We decided to choose the Global Style Extra 300 radiator model, but after their installation it became + 22 ° in the apartment (cast-iron batteries heated the air up to + 22 °). Why is it so cold if there are as many as 10 sections in a room (17 squares)? I'm disappointed".

Maria Streltsova, St. Petersburg.

Price

How more sections turned out when calculating, the more expensive heating radiators will cost. But in this situation, it is undesirable to save: if there is an excess of heat, you can screw on the tap, and if there is a shortage, you will have to buy additional sections, pay again for delivery and installation. The table shows the average price for 1 section, as well as the cost of 12-section batteries with different heat dissipation.

Radiator brand Global	Thermal power of the section	Price for 1 section / cost, rubles
Style 350	125	1100/13 200
Style 500	168	1125/13 500
Plus 350	140	1650/19 800
Plus 500	185	1700/20 400
Extra 350	120	11008/13 200
Extra 500	166	1150/13 800

Technical characteristics of radiators "Global"

The Global brand and its products were introduced in 1971. Thanks to extensive experience and continuous improvement of assembly technologies, the radiators of this Italian brand have become known all over the world. Today this brand is one of the leaders in the heating market. In 1994, the manufacturer entered Russian market and is rapidly mastering it. Since then, Global radiators have become even more reliable and sophisticated.

In our country, central heating does not differ in the quality of the coolant and the stability of the pressure, for which, of course, the Global batteries are prepared.

Development and modernization technological processes the production of high-strength radiators was facilitated by the purely Russian operating conditions of heating equipment. It's no secret that domestic centralized heating systems are distinguished by pressure instability and disgusting coolant quality. It is this and allowed to create equipment that can work in the most adverse conditions.

Subsequently, bimetallic radiators "Global" appeared on the market, which are distinguished by resistance to water hammer, high pressure, high temperatures and aggressive coolant. Thanks to this, the products of the Italian brand have earned positive assessments from Russian consumers - today, Global devices are installed in tens of thousands of houses and apartments.

Model lines

The following series of radiators are presented on the heating equipment market:

• bimetallic radiators Global Style Extra;
• bimetallic radiators Global Style Plus;
• aluminum radiators ISEO;
• aluminum radiators VOX.

Let's consider these lineups in more detail.

Bimetallic radiators Global

The Global Style Extra series differs from the Global Style Plus series in dimensions. One section of Style Extra radiators has dimensions of 415x81x80 mm for models with a center distance of 350 mm and 565x81x80 mm for models with a center distance of 500 mm. As for the Style Plus section of radiators, it has dimensions of 425x80x95 mm for models with a center distance of 350 mm and 575x80x95 mm for models with a center distance of 500 mm.

Technical characteristics of both model series - operating pressure 35 atm, pressure test 52.5 atm, maximum coolant temperature +110 degrees, connection diameter ½ or ¾ inch. Heat dissipation of Style Extra radiators is 171 W for models with a center distance of 500 mm and 120 W for models with a center distance of 350 mm. The heat dissipation of Style Plus is 185 W for models with a center distance of 500 mm and 140 W for models with a center distance of 350 mm.

If a shallow depth of radiators is important to you, choose the lineup Style Extra. Want to get the most out of your heat output? Then take a look at the Style Plus range. The price per section varies between 1000-1100 rubles.

Global bimetallic radiators are made of high strength steel and aluminum. Their sections are interconnected with paronite gaskets - this ensures that there are no leaks. The aluminum "jacket" is created by high pressure die casting, which provides excellent heat transfer from steel to aluminum. The aluminum itself is coated with a double layer of paint - thereby increasing the strength of the coating.

Aluminum radiators Global

Aluminum batteries from the Italian brand Global are distinguished by their resistance to poor coolant. For this they have a special fluorine-zirconium coating... It provides alkali and acid resistance, protecting Global batteries from penetrating corrosion. The maximum pressure in the heating system should not exceed 16 atm (test pressure is 24 atm). The maximum temperature of the coolant is +110 degrees. The permissible pH value of the heating medium ranges from 6.5 to 8.5.

As in the case of bimetallic models, the painting of aluminum radiators "Global" during production is carried out in two stages. The center distance is from 300 to 800 mm. Due to its technical characteristics, aluminum batteries quickly warm up the premises and no less quickly respond to changes in the temperature of the coolant.

Aluminum radiators "Global" will be a reliable solution for heating private households. V multi-storey buildings it is best to use bimetallic batteries.

The Aluminum ISEO range includes basic models with a center distance of 350 and 500 mm. Radiators with a center distance of 350 mm have dimensions of 432x80x80 mm, their heat transfer is 134 W per section. Models with a center distance of 500 mm have dimensions of 582x80x80 mm, heat transfer is 181 W. Devices from the Aluminum VOX model range are thicker - models with a center distance of 350 mm have dimensions of 440x80x95 mm, heat transfer is 145 W. Batteries with a center distance of 500 mm have dimensions of 590x80x95 mm and a heat transfer of 195 W.

All parameters are specified for one section. The connection diameter for Global aluminum radiators is ½ "or ¾". The price per section varies between 770-800 rubles.

Pros and cons of Global batteries

Italian radiators have a number of important advantages:

The inner metal pipes of the Global devices resist high pressure, and the aluminum jacket gives off heat excellently.

• high quality of metals used for their development;
• resistance to low quality of the coolant;
• high heat dissipation - up to 195 W, depending on the center distance;
• high-quality two-stage painting;
• reliable protection against leaks;
• high pressure resistance;
• compliance with all Russian and European norms and standards.

Not without some disadvantages:

• despite being protected against corrosion, Global aluminum radiators cannot be used in centralized systems heating ah;
• high price - on sale you can find cheaper models that are in no way inferior in quality.

Despite this, Global radiators continue to hold the leading position in the heating market.

Going to the official website of "Global", you can find information about the places where their products are sold. All licenses and certificates for manufactured products are also presented there.

Popular models of radiators "Global"

Global ISEO 500 is the most popular product of the Global brand.

Among the most popular models, we can highlight the Global ISEO 500 radiators made of aluminum...

In the Russian market, radiators from the Italian company Global Radiatori are very popular due to their high quality and wide range. The products of this manufacturer are designed taking into account the specifics of domestic heating systems. The most popular are the Global Vox aluminum sections and the Global-Style bimetallic sections (these radiators are very popular today).

Types of radiators

Heating radiators "Global" are produced in three varieties:

• bimetallic;
• aluminum;
• extrusion.

All types of products have their own characteristics, specifications, advantages and disadvantages, which will be discussed in more detail in the article.

Bimetallic radiators

Reliable, high-quality bimetallic radiators "Global" are the standard of quality. They are made of strong and durable materials. Products of the Style lineup are best radiators heating. In them, the part in direct contact with water is made of steel, and the outer part is made of aluminum.

Bimetallic radiators "Global" are intended for work in systems with high working pressure (up to 35 atmospheres) and can be installed both in central and autonomous systems heating ah. The most important advantage of this series is the thermostat, which is installed in the structure. It contributes to almost instantaneous provision of a comfortable air temperature for staying in the room. Bimetallic radiators, the price of which is about 850-900 rubles per section, are resistant to aggressive environments and corrosion, and also have high thermal conductivity. They are double-colored with heat-resistant compounds, which ensures their resistance to mechanical damage.

Features of bimetallic radiators "Style 500" and "Style Plus"

Bimetallic radiator 500 "Global" ("Style" series) is made in. It has a flat top, its height is 57.5 cm, depth - 8 cm, center distance - 50 cm, weight - 1.97 kg. The heat transfer of such a section is 168 W. This heating element can be used with different kinds pipes (metal-plastic, copper, polypropylene). The radiator "Global-Style" 500 consists of separate parts. The sectional assembly system using nipples allows you to increase the number of sections or reduce it.

Radiator "Global-Style Plus" has collectors of simple shapes without pockets, in which the formation of air congestion... Tubes are installed between them large sizes, which makes it possible to work with contaminated coolants. The design of the model allows you to increase the heat output due to the upper air chamber. Heating elements of the "Style Plus" brand are manufactured with the parameters of the center distance of 350 and 500 mm. For these bimetallic radiators, the price is approximately 10,100-10,200 rubles for 12 sections.

Advantages of bimetallic radiators

Bimetallic radiators from the Global manufacturer have a lot of advantages.

1. Ease of installation. Sections during installation can be removed or added.
2. Excellent thermal conductivity. Due to aluminum, which has good heat transfer properties, radiators have a high heat transfer rate. The coolant temperature can reach 120-135 ºС.
3. Strength. All products in production are tested by pressure testing in 52.5 atmospheres.
4. Long service life. This indicator is provided thanks to quality materials used in production.
5. Resistance to mechanical damage. The outer surface of the radiators is covered with powder enamel, which protects it from scratches and abrasions.
6. Resistant to aggressive environments. The interior of the radiators is made of high-strength steel, which is acid-resistant.
7. Attractive design. The white color, which is resistant to fading, is well suited to various interiors.

Extrusion radiators

Extrusion heating radiators "Global" Oskar are designed for vertical installation. This type of product is distinguished by the originality of the design, which consists of individual parts connected by Teflon sealing rings and adhesive sealant. Radiators have a light weight and exclusive design.

The manufacturer produces types of sections with different center distances - 100, 1200, 1400, 1600, 1800 and 2000 mm. This type of radiator requires certain characteristics of the water, which is the heat carrier. The hydrogen index should be at least 7-8 units, and water filtration from heavy elements is also necessary. This model has high heat dissipation, but inferior to strength, which does not allow it to be used in harsh operating conditions.

Differences between bimetallic sections and aluminum radiators

Radiators differ in production technology and material of manufacture. In addition, they have different operating and maximum pressures. This indicator is important when installing sections in multi-storey buildings with central heating, where there is an increased pressure in the system piping. In aluminum radiators, one metal is completely used, and in bimetallic, high-quality steel is used inside, and aluminum on the outside. It is very important to consider that an aluminum radiator is not suitable for installation if the heating system consists of copper pipes or the boiler has a copper heat exchanger.

Features of installation and operation of aluminum radiators

Since the operating pressure of the coolant in autonomous heating is low, reliable and inexpensive aluminum radiators "Global" are well suited here. Their installation does not differ from installation bimetallic sections, but there are some recommendations from the manufacturer that should be followed.

1. Radiators consisting of ten sections or more must be connected diagonally to the system, which makes it possible to increase their efficiency by 10%.
2. It is not recommended to install decorative elements on the front of the heating equipment. This helps to reduce the level of heat transfer from the radiators.
3. Heating devices with ten or more sections should be attached to additional brackets.
4. The service life of the equipment also depends on the quality of its care. To do this, before and during the season, you should systematically clean the surface of the sections from dust and dirt.
5. Do not install humidifiers made of porous materials on radiators. This can lead to water leakage, which will eventually damage the paintwork on the sections.
6. If the system will not be used in winter, then it is necessary to drain the water from it. V summer time it is desirable that the sections are completely filled.
7. It is not recommended to paint the surfaces of aluminum sections on your own, as this reduces their effectiveness.
8. You should not use various chemical additives or impurities that artificially increase the temperature of the coolant.

The efficiency and durability of Global radiators primarily depends on the performance of the heating system. Each type of section is designed for certain parameters of working conditions, and their installation must comply with all the manufacturer's requirements specified in the technical passport.

The Italian factory Global di Fardelli Ottorino & C, founded in 1971, is the world leader in the production of aluminum and bimetallic radiators. Wide application found Global products in Russia, the assortment allows you to purchase the best option for our homes. However, choosing a model is not the easiest process, for this you need to correctly assess the operating conditions and the possibility of installation in a particular room in advance.

Peculiarities

Among the advantages of Global radiators, it is worth noting durability, reliability, environmental friendliness, but most of all the Russian buyer is attracted by the focus specifically on our harsh conditions. Sectional batteries effectively cope with their task in conditions of unstable pressure and dubious quality of the coolant. The products fully comply with European and Russian standards.

Durability due to the use of special protection technology internal surfaces using a fluorozirconium coating.

It is worth highlighting a number of other advantages:

• high heat transfer - up to 195 W, depending on the center distance;
• reliable two-stage painting;

• effective protection from leaks;
• high quality of the metals used for the manufacture.

Among the disadvantages of the products, one can single out the high cost, however, this disadvantage is fully justified: without saving on the purchase of a heating system, the buyer receives high-quality radiators that will warm his house for more than one generation.

It should be noted that the manufacturer also produces mounting kits, including all accessories for installing batteries. The kits provide any option for connecting the device, regardless of thread size and installation method.

Views

Global offers the following types of heating radiators:

• bimetallic;
• aluminum;
• extrusion.

Radiator models have several variations that differ in size, center distance and heat dissipation. They can be identified by their name. For example, in the Iseo 350 the center distance is 350 mm, and in the Style Plus 500 version, the same figure is, respectively, 500 mm.

Bimetallic

Bimetallic devices are designed to operate in systems with high working pressure (up to 35 atmospheres).

Battery Benefits:

• the presence of a thermostat that contributes to the rapid achievement of a comfortable temperature;
• resistance to aggressive environment and corrosion;
• double painting provides resistance to mechanical damage.

The batteries are assembled from welded steel tubes around which aluminum fins are cast. Steel is used in the manufacture of the supply and return manifold and the vertical pipe connecting them. The welded single structure gains the advantages of both metals - the strength and stability of steel and good heat transfer from aluminum. Radiators assembled according to the "full bimetal" system are suitable for use in multi-storey buildings with centralized heating.

Aluminum

A special fluorozirconium coating provides resistance to alkalis and acids.

The pluses also include:

• coloring in production in two stages;
• fast warming up of premises;
• prompt response to changes in the temperature of the coolant;
• can be used in regions with very cold climates.

Global aluminum radiators withstand an operating pressure of 16 atmospheres, and are tested at 24, so they have long term service. The models differ in the depth of the sections, the number of duct ribs and their shape. Heat transfer depends on these indicators.

When choosing aluminum batteries, you need to take into account that they are not suitable for contact with low-quality water in urban central systems heating. They contain alkaline additives to reduce blockage in sebaceous pipelines. These impurities interact with aluminum, which provokes the occurrence of corrosion and the subsequent failure of the heating device.

Extrusion

These radiators are made using a different technology. The part with the plates is produced by the extrusion method: it is squeezed out, giving the desired shape, then the panels are pressed or glued to the cast manifolds.

The benefits include:

• low price;
• a light weight.

Extrusion batteries have thin walls, lower heat transfer and operating pressure, so they can be used only in individual heating... For Russian conditions, these radiators are not suitable; it is better to consider aluminum and bimetallic options for installation.

It was already noted above that interior bimetallic radiators are made of steel, and the outer one is made of aluminum. Steel is excellent as a coating in close contact with hot water and aluminum provides maximum heat dissipation.

The joints between the sections in the production are sealed with silicone gaskets, cover the equipment quality paint... The prestresses created in the process of crimping steel pipes under high pressure provide resistance to bursting water pressure and compensate for the difference in temperature deformation between steel and aluminum, thereby maintaining a constant heat transfer. The absence of pockets avoids the formation of air pockets.

Style Extra

The batteries are offered for use in any type of building with a central or autonomous heating system.

Specifications:

• pressing pressure - 3.5 MPa;
• coolant temperature - 110 ° С;
• dimensions - 415 x 81 x 80, 565 x 81 x 80;

The model immerses the inhabitants of the house in a European atmosphere with its unified, austere design. It is considered the most common bimetallic radiator in Russia. Among the advantages is a quick response to thermostat commands, which allows you to maintain comfortable heating in the room.

Installation and operating instructions for Global heating radiators are quite standard.

There are some rules to follow:

• For radiators with a length of 10 sections more suitable diagonal connection... According to the manufacturer, with lateral heat transfer will decrease by 10%.
• The use of decorative screens, gratings and boxes is not desirable. They can also reduce heat dissipation.
• When installing batteries up to 10 cells, three brackets must be purchased: two upper and lower. Longer radiators are mounted on three upper and two lower elements.
• Before installation, a project approved by the operating company is required.
• Assembly and disassembly of sections should be carried out gradually, without distortions.
• The adhesion of the nipple-nut and the manifold thread should be no more than 4 turns.

• It is better to use a torque wrench when screwing in the fittings. The process should not be done with effort.
• When using linen winding, it should not be wound too much in order to avoid the subsequent formation of microcracks. In general, in this process, a sealant is still preferable.

A common set for connecting a bimetallic radiator includes the following fittings:

• stubs;
• manual air vent (Mayevsky crane) and a key to it;
• two adapters with right and left threads.

Sami assembly work are not particularly difficult, but still, if you are an amateur in this matter, it is better to seek help from specialists. Heating radiators are not the kind of equipment, the installation of which is permissible for "and so it will do".

Operating rules

• Before using in heating season it is necessary to periodically clean the surface from accumulated dust and dirt.
• It is undesirable to install humidifiers made of porous materials, this can lead to water leakage and damage to the coating.
• If the equipment is not needed in winter, it is recommended to drain the water; in summer, on the contrary, it is necessary to fill the sections with water.
• It is better not to carry out independent painting works, this reduces the efficiency of aluminum sections.
• The use of chemical additives or impurities when caring for the battery is not recommended, as this can artificially increase the temperature of the unit.

• Pipes and radiators of heating networks cannot be used as elements of electrical circuits.
• Children should be supervised to ensure that they do not play with the air vents and air valves on the radiators.

How to choose?

For an apartment with central heating, it is better to choose bimetallic radiators; in the conditions of autonomous systems, aluminum batteries are suitable. Nevertheless, there are reviews that Global bimetallic batteries were not suitable for a home with central heating. To avoid such a situation, before buying, you need to find out the parameters of the coolant in the network: if the acidity is higher than 9.5, then you will have to install cast-iron batteries or look for models with a stainless steel frame.

If a shallow depth of radiators is important, you should pay attention to the Style Extra range. If you need maximum heat dissipation, you need to take a closer look at the Style Plus model.

Number of sections

To determine the number of sections in country house you need to calculate heat loss through all external structures - walls, ceiling, floor, doors, windows. In an apartment, it is enough to carry out a heat engineering calculation or use an online calculator. Scheme for counting the number of sections: the number of sections = S x 100 W / P, where S is the area of ​​the room, 100 W is the average specific heat transfer rate, P is the power of one section.

If the choice fell on the Global Style 500 model, then the number of links is determined by dividing the area of ​​the room by two. For example, a radiator of 10 sections is sufficient to heat a room with an area of ​​20 meters.

Price

Prices depend on the number of sections. You should not save on the purchase - if there is an excess of heat, it is possible to screw on the tap, and if there is a shortage, you will have to buy additional links, which threatens with new costs for delivery and installation.

Approximate prices for aluminum versions of Iseo and Klass start at 540 rubles per section. The Vox model costs a little higher - from 565 rubles per section. The purchase of Global Style Plus bimetallic batteries will cost at least 850 rubles, and the cost of one Style Extra and Style section is 810 rubles.

Design

If there is a deep niche in the wall, and the window sills are large, then a model from the Plus line is suitable for installation: its depth is 15 mm more than that of Style, there are additional ribs on the sides, heat transfer is higher. The design of Global radiators is in many ways superior to competitors, so they will neatly fit into any interior.

Thus, choosing a heating radiator manufactured by Global must be carefully selected., the comfortable temperature in the room directly depends on this. The main thing is to do correct calculations and make sure that the model you like is suitable for heating your home. Study the operating conditions of the premises and determine the model.

In the next video you will find more information about Global radiators.

The Italian company Global has been producing heating radiators since 1971. For almost half a century of history, a small workshop has grown into a large enterprise with its own plant and laboratories. It also supplies aluminum radiators to the Russian market.

Global aluminum radiators are presented in a wide range. These are Vox and Vox Extra, Iseo and Klass, VIP, GL and Oscar, all models are able to withstand serious water hammer in the centralized heating system.

The main advantage of Italian aluminum heating radiators is high heat transfer. Aluminum is an excellent conductor of heat, thanks to which one battery can heat a large room. These radiators have other features:

• Aesthetics. The batteries will perfectly fit into the interior of a private house or a luxurious city apartment; they do not require the installation of screens.
• Sophisticated design. All models are suitable for installation under windowsills and in niches: thanks to the numerous ribs, air flows freely between the sections and heats up quickly.
• Versatility. You can use radiators with pipes made of steel, metal-plastic or polymer pipelines. Leaks and other problems are excluded.
• Sectional structure. Each element is attached to each other with nipples using special three-layer gaskets. The radiator can be reduced or enlarged by adding several sections, making the heating system as efficient and economical as possible.

Italian aluminum radiators are an excellent choice for stand-alone heating systems... They are suitable for almost any heating medium. Thanks to their reinforced construction, they will last over 10 years in a city apartment with centralized heating.
