Like any other device, aluminum radiators have their pros and cons. They differ from their analogues in high heat transfer, low weight and attractive appearance. However, their Achilles heel is corrosion. You should carefully choose the manufacturer and device so that it will serve you long enough.
First, let's figure out what aluminum radiators are. Today there are three types of aluminum radiators: extruded, cast and anodized. The first type is extruded in an extruder at high pressure and pressed with the remaining parts. The second type is made using injection molding technology. An alloy of aluminum and silicon is used for production. The third type is the most expensive and is made from highly purified aluminum with anodic oxidation of the entire surface. All of the above devices are capable of responding to changes in coolant temperature in a short period of time. However, these are not all the features. KP has compiled a rating of the top 10 best aluminum heating radiators.

I selected a radiator based on power to replace a steel one from the developer. I was choosing between Rifar and Stout. The Russian radiator turned out to be more expensive than 12.5 thousand versus 9.5 thousand. Moreover, it was captivating that it was made in Italy. The radiator is connected and heats up to full capacity. The plumber assured me that the outer sections would not warm up, but I didn’t notice this from the feel. The color is not crystal white, but a little yellowish, but this is not critical. Very light compared to steel. The metal feels quite thick - the ribs do not bend or press under the pressure of your fingers, like in Chinese ones. Overall I'm happy with it so far.
Global VOX EXTRA 500
Heating devices are designed to heat rooms with an area of 18.4 square meters. m. Despite their small size, the batteries are distinguished by high heat transfer and long service life, which is due to the thermal conductivity of aluminum, and look organic in any room.

We have had this radiator installed for several years now. We are very pleased. First of all, it makes your home very warm during the winter months. When it gets warmer outside, we simply adjust the heat. Temperature changes occur very quickly. Secondly, the radiator looks much nicer than the old cast iron ones and takes up much less space. The model is very light compared to cast iron radiators.
Rifar Alum Ventil 500
The main difference between Rifar Alum Ventil 500 and well-known aluminum radiators is the design of the vertical channel of the section. The technological hole in the lower part of each radiator section is closed without welding using a special plug and sealing gasket.
This ensures the tightness of the radiator when using not only water as a coolant, but also oil and all types of non-freezing liquids (antifreeze). The high fluidity of such liquids does not allow their use in conventional welded aluminum radiators due to leaks in the weld area caused by the high porosity of aluminum in this place.
Models of this type are convenient and functional to use as an attractive option for replacing the main heating system. Radiators of this type can fit into traditional modern heating systems used in typical urban and private suburban construction.

I also like the radiator when cleaning, it does not cause any problems, you can easily clean both behind it and under it. Another advantage is that there is no need to paint, unlike cast iron.
Advantages and disadvantages of aluminum radiators
One of the advantages that brought aluminum radiators to the top of sales was their quite affordable price. In addition, these heating systems differ:
- small dimensions and light weight;
- attractive appearance, allowing them to be used to decorate premises in any style;
- ease of installation work and the ability to regulate the temperature using special regulators;
- short heating and cooling time of heating devices;
- the presence of large diameter pipes, which does not allow them to quickly become clogged;
- the ability to adjust power by reducing or increasing the number of vertical sections;
- long service life - from 10 to 25 years.
During the heating process, the aluminum alloy from which the system is made does not emit substances harmful to health, and the powder enamel with which the radiators are coated does not emit a specific odor and does not require regular painting.
A few disadvantages of aluminum radiators should also be listed:
- sensitivity to changes in pressure in the heating system;
- the possibility of corrosion processes occurring as a result of increased acidity of the coolant;
- the need to regularly remove air that inevitably accumulates in the collectors;
- the occurrence of leaks in the area of sectional joints;
- poor compatibility of aluminum batteries with steel or copper pipes, and the occurrence of electrochemical corrosion at the junction.
However, most modern manufacturers use special aluminum alloys and carry out additional anti-corrosion treatment, which reduces the list of disadvantages of aluminum radiators.

Methods of stylistic decoration
The simplest option for disguising an unsightly radiator that does not fit with the stylistic decision in the design of the room is considered to be a screen. This is most often a ready-made panel with holes that is used to cover the battery. It can be suspended or built into a special box, that is, it can completely hide the radiator. Screens are made of glass, MDF, metal. There are also wooden panels that look like “wicker”. The color of their surface is selected to match the furnishings of the room. Glass is ideal for modern “high-tech” styles. Metal screens are often made with forging elements. Floral motifs will fit in an original way into country or classic style. Radiators can be decorated not only with the help of screens. The simplest, budget-friendly methods include painting. Colored radiators are combined with the shade of curtains, walls, or make the radiator an accent of the interior. Sometimes the unit is covered with strips of wallpaper, thereby completely masking the surface. Black, gray, white radiators are combined with loft, minimalism, high-tech, futurism and avant-garde. Sometimes fabric curtains are used, which are attached to the windowsill. A similar cozy solution in the style of Provence, eclecticism, ethnicity or classic looks appropriate. Using putty, the drawing is given additional volume. Copper radiators are decorated with artificial patina, aging the surface.
In some cases, radiators are skillfully decorated to look like a “fireplace”. On the sides of the battery there are shelves for books and decorations. It’s worth remembering: the deeper the battery is hidden, the more it will affect its performance.
How to choose an aluminum radiator
Heating devices made of aluminum have a decent appearance, are not very expensive, and in terms of heat transfer they have become leaders among all heating devices. They are produced by a large number of companies and they all have their own design features that you need to know. Therefore, we suggest studying the criteria for choosing this equipment.
- Molded. Molded-type radiators have a higher cost. During their manufacture, each section is cast under pressure from an aluminum alloy - silumin. This alloy contains up to 12 percent silicon (for strength). All connections of individual elements are made by welding in an inert gas environment. The manufacturability makes the radiators durable. Radiators of the required thermal power are formed from separate sections.
- Extrusion. To reduce the cost of producing aluminum radiators, the extrusion method was used to manufacture the central part. The part is not cast, but extruded in an extruder at high pressure. Then it is pressed into place with the upper and lower manifolds (they are cast). Often, a composite adhesive is used to join the battery parts together, which makes the finished product even cheaper. The extrusion radiator cannot be disassembled.
- Manufacturer. The best companies in this segment are Global, Sira, Ferroli. Can also be called Calidor and Faral. Radiator models produced by Italian manufacturers are distinguished by style, elegance of shape and excellent finish.
- pH indicator. When buying these heating devices, remember that any aluminum radiator, even the most “promoted” manufacturer, is afraid of water with a high pH level. In no case should it exceed 7.5 units. Therefore, it makes sense to install heating devices made of aluminum only if the coolant in the system meets these requirements.
Cast radiators
With the casting method, an alloy is poured into molds, then silicon is added for strength. Thanks to this, the radiator sections are sealed and can withstand pressures of up to 16 bar. During testing, the batteries are subjected to pressure testing at 25 bar.
In addition, the vast majority of radiators have fins in the shape of petals, which play the role of convectors to position the direction of the warm air flow into the heated room. Depending on the number of such channels, heat transfer and heat transfer will increase.
Cast aluminum radiators are divided into collapsible sections, so the number of sections can be reduced or increased to increase or decrease the thermal power. Thus, a failed section can be easily replaced with a new one.
How to connect
Aluminum radiators are suitable for both two-pipe and single-pipe wiring. In the first case, the connection of the supply pipe and the outlet pipe occurs in parallel; they are independent of each other and are connected through the final device of the heating system.
With single-pipe wiring, the coolant passes through one pipe sequentially through all radiators, gradually cooling down.
There are several schemes for connecting aluminum devices:
- diagonal;
- lateral;
- lower.
All schemes differ from each other not only in the installation method, but also in the quality of heat transfer.
- Diagonal. The most effective and common installation method is a diagonal connection (heat loss is no more than 2%). The method is well suited for radiators with a large number of sections. The supply pipeline is connected to one of the upper pipes. The outlet pipe is connected to the bottom one from the opposite side. This piping method is used mainly for two-pipe heating systems, because with a one-pipe system the coolant noticeably loses heat as it passes through each radiator. The disadvantage of such a connection lies in its aesthetic unattractiveness, since the pipes run along the upper edge of the heating devices.
- Lateral (unilateral). The scheme is similar to a diagonal connection: the hot water supply pipe is on top, the outlet pipe is on the bottom, but the installation is made to pipes located on one side. It is important not to mix up the pipes or swap them. This method is more often used in multi-storey buildings with small radiators. It is not suitable for devices with more than 15 sections, since with a larger number, the far (opposite to the connection point) side of the unit does not heat up well.
- Lower. This connection is made to the pipes located at the bottom of the heating device. This installation scheme allows you to hide the heating system pipes under the floor, which is beneficial from a design point of view. But the heat transfer with such an installation is much lower (about 15% less than the rated power of the radiator).
Convectors
Convector heating is the most modern way to maintain the desired temperature in an apartment.
The operating principle of convectors is that these systems use natural circulation of warm air to heat the space.
There are 2 main types of convector:
- Water;
- Electric.
Water convectors allow you to control the microclimate literally in manual mode, which is very convenient. But such systems are quite difficult to install; their installation requires a pipeline with hot water.
Electric models are much simpler in terms of installation; they are considered the most modern and easy to use. All they need is a connection to the mains via an outlet.
Convectors can even be installed on the floor - an ideal solution for those who want to free up space to the maximum and remove all unnecessary (and not entirely unnecessary) items from the interior.
Which is better, aluminum or bimetallic?
If you find it difficult to choose which heating radiator is better - aluminum or bimetallic - just compare the main criteria:
- Heat dissipation. In terms of this parameter, the devices practically do not differ; the heat transfer of one section in both cases is about 200 W.
- Resistant to high pressure. Aluminum models can withstand 16 Bar, and bimetallic models can withstand 35 Bar. This criterion is of key importance if operation is planned as part of a central heating system.
- Sensitivity to the composition of the coolant. Aluminum reacts with many chemical compounds present in the coolant from the central heating system. In addition, it is susceptible to oxygen oxidation.
- Maximum permissible coolant temperature. For aluminum models, this parameter corresponds to 110 degrees Celsius, and for bimetallic models – up to 130 degrees Celsius.
- Price. On average, the price for bimetallic models is 20-30% more than for aluminum ones.
Batteries as an element of furniture
The principle of multifunctionality is now in trend. And if you manage to turn the battery into a piece of furniture, it will be a very convenient and stylish solution.
Now there are radiators that can be shelves, tables and even benches. Thanks to this approach, the necessary heating device acquires an additional role in the interior, which is no less important than creating a comfortable microclimate. When the radiators are turned on, it is especially pleasant to use such furniture - it is always very warm and cozy here.
Important: such solutions must be well thought out, ideally ready for use. An ordinary battery cannot be converted into a piece of furniture at will, as this will be too dangerous - if the structure cannot withstand the load, it will lead to an accident. The safest and most aesthetic option is to replace outdated batteries with modern models that not only provide heat, but also make your home more beautiful and comfortable.
Calculation
For sectional
If the required room is of non-standard size, then it is better to choose a sectional heating device. The number of segments must be correctly calculated so that there are no unnecessary costs or lack of heat.
By volume. It is produced in the following sequence:
- Determination of heat requirements according to standards. According to building codes, the amount of heat required for a room is 41 watts per cubic meter, but these calculations apply to insulated buildings. If the building is poorly insulated, then the indicator should be increased to 50 W/m3. If there is a layer of insulation on the walls of the room, and plastic windows are also installed, the figure is reduced to 30 - 34 W/m3.
- Calculate the required number of sections. The first step is to calculate the volume of the room that needs heaters.
- We will calculate using the example of a room 4 m wide, 5 m long and 3 m high ceiling. We multiply the values and get a volume of 60 m3.
- Determining the heat requirement for an apartment. The apartment has average insulation without an additional layer. The value for it is close to 41 W/m3. We multiply the indicator with the volume of the room, the result is 2460 W. This amount of energy is needed to provide heat to your room.
- Pay attention to the amount of heat generated by one section of the battery you choose. Modern samples produce power in the following range - 80-212 W. We take the average value of 170 W for calculation. The amount of heat required is divided by this value, and then the resulting amount is rounded up. We get 15. This is exactly the number of sections needed to heat the given room.
There is also a simpler method; it is used for rooms with ceilings of 2.6 meters.
Calculation by area. With this calculation, you only need to know the length of the walls of the room. Let's look at the example of a room similar to the previous one, but the ceilings there will be less than 2.6 meters. With this calculation, a requirement of 100 W/m3 is taken, regardless of the conditions.
- We calculate the area of the room. It is 20 m2.
- Determination of the amount of heat required for heating. We multiply the need by the area, the result is 2000 W.
- Now you need to find out how much heat transfer one section of the battery has. As in the previous calculation, we take a value of 170 W. The need for the premises is divided by it, and the result is rounded up. According to calculations, we found that for the room given in the example, 12 sections are needed.
For whole
Calculation of heat for solid batteries does not differ from sectional ones until the stage of calculating the amount of heat required by the room. If in the previous examples you divided the resulting value by the heat transfer of the section, then here you compare the heat indicators. Necessary for the room and the one to which the heating device you choose corresponds.
If the number of watts generated by the battery is lower, it is necessary to install an additional climate control device that will cover the lack of necessary heat.
Both types of calculations assume that the height of the ceilings in the room does not exceed 3 meters, so they will not be suitable for higher heights. In such rooms, the number of sections is determined by heating engineers.
