Which Global radiator to choose?

The Italian factory Global di Fardelli Ottorino & C, founded in 1971, is the world leader in the production of aluminum and bimetal radiators. Global products found wide use in Russia as well, the range allows you to purchase the best option for our homes. However, the choice of model is not the easiest process, for this you need to properly assess in advance the operating conditions and the ability to install in a given room.

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 orientation specifically for our tough conditions.Sectional batteries effectively cope with their task in conditions of unstable pressure and dubious quality of the coolant. Products fully meets European and Russian standards.

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

It is worth highlighting a number of advantages:

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

• effective leakage protection;
• high quality metals used for manufacturing.

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

Global offers the following types of radiators:

• bimetallic;
• aluminum;
• extrusion

Models of radiators have several variations, which differ in size, center distance and heat emission. They can be identified by name. For example, the Iseo 350 has a center distance of 350 mm, while in the Style Plus 500 version, the same figure is, respectively, 500 mm.

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

Battery Benefits:

• the presence of a thermostat conducive to the rapid achievement of a comfortable temperature;
• resistance to aggressive environment and corrosion;
• double coloring 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 tube connecting them. The welded single construction receives the advantages of both metals - the strength and stability of steel and the good heat transfer of aluminum. Radiators assembled on the “full bimetal” system are suitable for use in high-rise buildings with centralized heating.

Special fluorozirconium coating provides resistance to alkalis and acids.

The advantages should also include:

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

Global aluminum radiators withstand a working pressure of 16 atmospheres, and are tested at 24, so they have a long service life. The models differ in the depth of the sections, the number of edges of the air ducts and their shape. The heat emission depends on these indicators.

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

The benefits include:

• low price;
• a light weight.

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

The aluminum model is perfect for heating residential and office buildings with an independent connection to the heating system, in cottages and other premises with independent heating, such a radiator would be appropriate.

• coolant temperature - 110 ° C;
• working pressure - 1.6 MPa.

A special feature of the model is high-quality processing using a two-step dyeing technology - complete immersion of the structure in a paint bath and subsequent spraying with epoxy material based on polyester. Due to this, the battery has a neat appearance. Model type Klass is one of the newest from the manufacturer. Variable series begins with the serial number 500-01 and ends with the model Klass 500-14.

Typically, the bimetallic Style Plus model is used in buildings with central or autonomous heating systems.

Specifications:

• pressure - pressing 5.25 MPa;
• coolant temperature - 110 ° C;
• dimensions - 575 x 80 x 95, 425 x 80 x 95;

The model immerses the inhabitants of the house in the European atmosphere with its unified strict 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 operation instructions for Global heating radiators are quite standard.

You must follow some rules:

• For radiators with a length of 10 sections, a diagonal connection is more suitable.As stated by the manufacturer, with side heat transfer will be reduced by 10%.
• It is not desirable to use decorative screens, grids and boxes. They can also reduce heat output.
• At installation of batteries to 10 sections it is necessary to get three arms: two top and lower. Longer radiators are mounted on the top three and two bottom elements.
• Before installation, a project is required that is agreed with the operating company.
• Assembly and disassembly of sections should be carried out gradually, without distortions.
• The coupling of the nipple-nut and the thread of the collector should be no more than 4 turns.

• When screwing reinforcement it is better to use a torque wrench. The process should not be carried out with effort.
• When using flax, it should not be wound a lot to avoid the subsequent formation of microcracks. In general, in this process, sealant is still preferable.

The usual set for connecting a bimetallic radiator includes the following fittings:

• caps;
• manual air vent (crane Mayevsky) and the key to it;
• two adapters with right and left thread.

• Before using during the heating season, periodically clean the surface from accumulated dust and dirt.
• It is undesirable to install humidifiers made of porous materials, it threatens with water leakage and damage to the coating.
• If the equipment is not needed in winter, it is recommended to drain the water, while in summer, on the contrary, it is necessary to fill the sections with water.
• It is better not to carry out independent painting work, it reduces the effectiveness of aluminum sections.
• The use of chemical additives or impurities in the care of the battery is not recommended, it can artificially increase the temperature of the installation.

• Do not use pipes and radiators of heating networks as elements of electrical circuits.
• Ensure that children do not play with valves and an air vent installed on radiators.

For an apartment with central heating it is better to choose bimetallic radiators, in conditions of autonomous systems aluminum batteries will be suitable. Nevertheless, there are reviews that Global bimetallic batteries are not suitable for a house 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 above 9.5, you will have to install cast iron batteries or look for models with a stainless steel frame.

To determine the number of sections in a country house you need to calculate the heat loss through all external structures - walls, ceiling, floor, doors, windows. The apartment is enough to conduct a thermal calculation, or use an online calculator. The 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 standard heat transfer rate, P is the power of one section.

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

Prices depend on the number of sections. You should not save on the purchase - with an excess of heat it is possible to fasten a crane, and with a shortage it will be necessary to buy additional links, which threatens with new costs for delivery and installation.

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

If there is a deep niche in the wall, and the window sills are large, then the model from the Plus range will be suitable for installation: its depth is 15 mm greater than that of the Style, there are additional fins 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 Global heating radiator must be carefully considered., the comfortable temperature in the room directly depends on it. The main thing is to make the right calculations and make sure that the model you like is suitable for heating your home. Examine the conditions of use of the premises and determine the model.
