The radiator is bimetallic or aluminum. Features of choice

The best radiator manufacturers

It is worth noting! The most reliable brands that manufacture aluminum radiators are:

Rifar. A domestic manufacturer that produces high-quality equipment using Italian innovative technology. A special feature of the radiators is a long warranty period of 10 years.
Global. An Italian brand that produces radiators with reference quality. The equipment can be used both in apartments and private houses. The products are characterized by high working pressure.
Royal. This brand produces budget models of aluminum radiators. They can withstand high pressure thanks to a special casting technique. The original design makes the batteries very popular among consumers.
ROMMER. The equipment is produced using European technologies, is of high quality, and can cope with heavy loads. Affordable price complements all the advantages.

Aluminum battery device

When considering the design of an aluminum heating radiator, it should be noted that the design of the battery can be solid or sectional.

A sectional aluminum heater consists of 3-4 separate sections. As a rule, titanium, silicon, and zinc are added to aluminum. These metals make the product stronger and more resistant to tearing and corrosion. All sections are connected to each other using a threaded connecting element. Silicone gaskets are used to seal the connection. The radiators have a polymer coating inside to prevent the possibility of battery rupture.

Solid aluminum radiators consist of profiles. Profiles are made by extrusion.

No additional metals are added to aluminum radiators.

What gives plasticity to the material. The profiles are connected to each other by welding. This connection is highly durable and reliable. Like sectional ones, one-piece radiator models are coated inside with a polymer layer.

Depending on the production method, there are radiators made by casting, extrusion and anodized products (made from aluminum of a higher purity).

Technical characteristics of aluminum heating radiators

Due to its high technical characteristics, many people decide to buy an aluminum radiator for heating their apartment. The main technical parameters include:

operating pressure. It ranges from 10 to 15 atmospheres. In residential apartments, operating pressure can exceed the norm by 3-4 times. In this regard, such radiators are rarely installed in city houses. But for private homes, such a heater will be an ideal solution;
crimping pressure. Located in the range from 20 to 50 atmospheres;
heat transfer coefficient. For the standard section it is 82-212 W;
the maximum coolant temperature can reach +120 degrees;
one section can weigh from 1 to 1.5 kg;
capacity of each section is from 0.25 to 0.46 l;
the distance between the axes can be 20, 35, 50 cm. There are models in which this parameter can reach 80 cm.

The manufacturer indicates the parameters for each radiator model in the device passport. Considering the technical characteristics of aluminum heating radiators, the price for them is quite justified and depends on the type of battery, the number of sections and the manufacturer.

Advantages and disadvantages of aluminum radiators

Before you buy aluminum heating radiators, you need to consider what advantages and disadvantages this device has.

The main advantage of an aluminum battery is its compactness and much lighter weight than cast iron systems. You can read more about cast iron heating radiators here. The equipment warms up very quickly and transfers heat well to the room. The service life is quite long. Another advantage is the division into sections - it is possible to select the desired length of the battery. It should be noted that for aluminum radiators the price is indicated per section. This makes it easy to calculate the approximate cost of a sectional device.

Since the equipment is small and weighs little, it is easy to install. Installation can even be carried out on a plasterboard wall. Modern models look aesthetically pleasing and stylish. Aluminum is easy to process. This gives manufacturers the opportunity to experiment with battery design. You can choose an option for any interior. Aluminum radiators are most suitable for autonomous heating systems. Despite the high technical characteristics and a lot of advantages, the price of aluminum heating batteries is quite affordable.

The disadvantages of aluminum radiators include low resistance to corrosion. And this can greatly affect the overall condition of the battery. Aluminum is a fairly active metal by nature. If the oxide film covering the surface is damaged, the protective layer will be destroyed due to the release of hydrogen. To increase anti-corrosion properties, a polymer coating is used. If the battery does not have a polymer coating, then you cannot turn off the taps on the supply pipes. Otherwise, the battery may rupture under pressure.

What characteristics should you pay attention to when choosing aluminum radiators?

Important! Radiators differ from each other not only in their exterior. There are a number of parameters that need to be taken into account when purchasing:

Type. The devices are anodized - they can withstand high pressure, are resistant to corrosion, and have great heat transfer; extruded - produced using the technique of extruding individual parts, connected into a finished product by welding or gluing; cast - made by injection molding, using an alloy of aluminum and silicon. The latter are considered the most popular option.
Acid-base balance range. This indicator is especially important when purchasing a radiator for an apartment, since in a private house the owner can independently control the quality of the water.
Height . It is selected in accordance with the installation location and the location of the connection pipes.
Thermal power. Determined according to the area that needs to be heated. Manufacturers usually indicate the power of one section.

What are the types of aluminum radiators?

Aluminum is highly reactive and occurs in nature in the form of compounds.
Aluminum products, including heating radiators, are alloys.

Aluminum-silicon alloys (silumins) have good ductility and casting properties.

According to the production method, aluminum batteries are divided into:

Cast.
Extrusion.
Combined.

Casting method. Each section is cast in a separate mold under high pressure. In the future, the sections will be assembled on nipples. The silumin content in such radiators is about 12%. More metal comes out than with the second method. To reduce the cost, recyclable materials are used.

Extrusion method. The molten metal is “squeezed out” through the forming holes and then joined (joining methods: nipples, adhesives and boring, manufacturers try to keep secret). The battery sections are fastened together and can no longer be added or decreased. Although the extruded metal itself is more expensive, the cost of such a radiator is lower due to the economical consumption of materials. The composition includes alloying additives, and no recycled materials are used.

Combined method. Some parts of the radiator are cast (horizontal collectors), while others are made by extrusion (vertical channels). This achieves the best value for money.

The times when all radiators were the same are long gone. Nowadays the market offers a variety of design solutions and all kinds of materials. Bimetallic batteries: which ones are better? Comparative characteristics of radiators and features of choice.

Device Features

The models offered by modern manufacturers are distinguished by great reliability and high performance. They become most effective when they match the technical parameters of the heating system with which they work. Some models are suitable for heating large rooms, others for smaller spaces.

The design of a heating radiator covers such parameters as design design, material of manufacture, performance characteristics, and determines the following factors:

Operational capabilities of the model.
The type and quality of coolant that will be used in the system.
Operating pressure.
Connection option.
Various installation nuances.

The operating principle of heating radiators is incredibly simple. The heat-carrying medium (water, oil, steam), which has the required temperature, continuously moves through the pipeline. As a result, it ends up in a heating device, due to which the air temperature in the room increases.

When choosing a battery, imported or domestic, you need to remember the operating conditions in existing heating networks. The centralized heating system is characterized by fluctuations in temperature and pressure, and poor quality of the coolant.

Depending on the method of heat transfer, the units are classified as follows:

Convectors. Heat from the heating element is transferred to the room due to the exchange of air flows with different temperatures. This process is called convection. During this process, the air, which has become warm after contact with the heating element, tends upward and gives way to cold currents. Gas and electric convectors are used for heating.

Radiators. Heat is radiated from the heated surface, the temperature of which increases due to the movement of the coolant through the pipes. This is the operating principle of the equipment traditionally used in our homes.

Manufacturers also offer combined type heating units. In such convector-radiators, most of the heat is generated by energy radiation, and the rest is generated by convection. Thanks to this, the quality of room heating is significantly improved.

Classification by material

To understand how a heating battery works and decide on the choice of model, you need to study the various options for such devices. For example, the material of manufacture affects the performance, functionality and durability of the entire system.

Manufacturers offer radiators made of the following metals:

Cast iron

Such radiators are reliable in operation and resistant to corrosion, and have low thermal conductivity. Despite their heavy weight, they are still in demand due to their low price. In the system they usually have a one-way connection. Although this scheme is the simplest, it requires a large volume of coolant to maintain a constant temperature and significant circulation.

Steel

Such batteries are most often used by owners of private houses. They are distinguished by their aesthetic appeal, dissipate heat well, weigh little, and are easy to install yourself. Among the disadvantages are they are afraid of water hammer and react poorly to oxygen in pipes.

Aluminum and bimetal

These are lightweight and reliable devices, but corrosion is their bane. For private and apartment buildings, different options are offered depending on the pressure the device can withstand.

Equipment made of steel and aluminum (bimetal) can be connected in different ways. Its characteristics are better than those of cast iron counterparts. Bimetallic batteries can pass much less hot water through them, while their contact area with air is larger.

Varieties by shape

Equipment options can be divided into sectional, tubular, panel and plate. All of them are successfully used in residential construction. Some are optimal only for private houses, others – exclusively for multi-storey houses.

Sectional

They are formed by separate ribs connected to each other by nipples. Most often they are made of cast iron, aluminum and composite materials. They are most popular because they allow you to regulate the power yourself. To do this, it is enough to increase or reduce the number of sections.

Studying the structure of a cast-iron heating battery in cross-section, you can see the collectors at the top and bottom that form horizontal channels. They serve to move coolant. Debris and large impurities settle in the lower channel, which helps to avoid clogging of the entire unit.

The main disadvantage of sectional devices is the possibility of leaks at the points where the sections are connected. To avoid this problem, it is recommended to carry out installation taking into account the properties of the materials from which they are made.

Tubular

In them, the coolant moves through tubes. The main design details are the collectors located at the top and bottom. Vertical elements are used to connect them together. The thermal conductivity of such a sealed structure depends on the size, number, diameter and material of the tubes. On sale you can find models not only with a round, but also with an oval or rectangular cross-section. The dimensions of the equipment also vary significantly. This allows you to successfully fit it into the interior.
