How to choose and what to look for?

• Monolithic is better in performance: even strong water hammers are not afraid of him, he can withstand the enormous pressure of the coolant, there can be no unpleasant leaks between the blocks, and his service life - just imagine! - 100 years. However, you will not be able to reduce or add sections as you wish, and the price tag for such models will be very high.
• Sectional ones are cheaper and allow you to choose the number of sections yourself.
• The standard distance between the lower and upper manifold is from 200 to 800 mm. Sizes from 800 mm must be ordered individually, and 200 mm are rarely found on the market.
• When choosing a company, it is important not to miscalculate. The following are considered the most reliable: Royal, Global, Rifar, Sira, STOUT. It should be remembered that European brands are distinguished by high quality materials and workmanship, but they cannot always be adapted to Russian heating networks.
• In some models, the frame consists entirely of steel, in others, only the channels through which boiling water flows are reinforced with steel.. The first option is more reliable and better, such radiators do not leak and do not suffer from corrosion. But the latter have higher heat transfer and lower cost.

Types of bimetallic radiators

By design, radiators are divided into sectional and monolithic. Sectional give the buyer the opportunity to choose the number of sections.

Joints are sealed with heat-resistant rubber gaskets.

They require a special mode of use, since the joints of the components are destroyed over time.

Large heat transfer area. Monolithic, i.e. solid, the structures withstand much greater hydrostatic pressure and last longer (up to 50 years).

One section is capable of delivering 100-200 watts.

The cases in such models are cast as a whole, followed by pressure treatment and application of a layer of aluminum on a steel frame. They cost more than sections.

Advantages and disadvantages of bimetallic radiators

Advantages:

• Good heat dissipation and maximum working pressure.
• Reducing the quality of the coolant for them is not a problem.
• The service life of such units is several decades.
• Due to the steel core, even strong hydraulic shocks are not afraid of the system.
• Corrosive processes for bimetallic radiators are not terrible.
• The reaction of such a thermostat is very fast.
  They look very attractive in appearance: they are made not in boring white, but in multi-colored scales, and on top they are also covered with an additional protective layer.
• They are very easy to install, thanks to a well-thought-out connection system.

Flaws:

• You will have to pay a high price for such a radiator: much higher than for a device made of aluminum or cast iron.However, it will pay off quickly.
• The cross-sectional area of ​​a bimetallic radiator is somewhat smaller than that of analogues, due to which heat transfer is reduced (but not much).
• The hydraulic resistance is higher, which means that more power is required to pump water through the system.

Which firm to choose?

The most popular on the market today are:

• Italian: Fondital, Global, Sira, Royal Thermo. It is Italy that is the birthplace of bimetallic radiators, and still stands out among competitors with the ability to create not only a high-quality, but also an aesthetically attractive product. A section costs about a thousand rubles, design developments are much more expensive, but you can fit such a radiator into any, even the most “fancy”, interior.
• Russian: Rifar, STOUT. A high place in the world ranking is occupied due to the applied butt welding method and the ability to withstand extremely high temperatures.
• Polish: REGULUS-system. The price tag is low and the quality is excellent.
• South Korean and Chinese. Excellent value for money and quality.

Aluminum or bimetal radiator - which is better?

Aluminum:

• do not have a core;
• made of one metal;
• heat transfer is 15-20% higher;
• are lighter and easier to install;
• serve 20-25 years;
• if the pH level rises in the water, corrosion occurs, the walls gradually
• become thinner and a leak appears;
• they are unstable to high pressure;
• do not tolerate the absence of coolant at the time of its discharge.

Bimetallic:

• expensive;
• operation is also possible at high moisture temperatures;
• withstand pressure up to 24 atmospheres;
• practically do not depend on the quality of the coolant (fluctuations in pH and unfavorable environment);
• steadfastly accept water hammer;
• resistant to corrosion;
• if air gets into the pipe, rust will appear;
• plastic.

In a high-rise building, it is better to put bimetallic ones.

Steel or bimetallic - what to choose?

Steel batteries have a lot of fans. And this is not surprising: they look stylish, are easy to install, and have above average heat dissipation.

The cost is also low. However, the parameters of the working pressure are so low that they cannot withstand water hammers, even of medium power (only the working pressure of the boiler room is on their “shoulder”), and they are subject to corrosion.

In addition, they are not covered with a protective paint coating on the outside, which means that they do not have rust protection on the outside..

Barometric load up to 40 atm does not interfere with bimetallic units, therefore they are not afraid of pressure surges. They heat better than others, practically do not accumulate lime on the walls, they are light, they serve for a long time.

Sections can be arranged and selected as needed.

As you can see: both the first and the second merits are approximately equal. If the buyer has money, he will prefer to choose bimetallic radiators.

For construction organizations, steel ones are a priority, since they are cheaper.

Cast iron or bimetallic - which one to choose?

Cast iron is a classic, popular back in Soviet times. It cools for a long time (and transfers heat longer), is resistant to aggressive liquids and abrasive particles, it can be painted to your heart's content. But in order for the cast-iron battery to warm up properly, it will take a lot of time.

Bimetallic units are designed externally more modern, reliable and easy to install..

They need very little water to work well. But the service life of the radiator depends on its quality, and here it should be noted that carrying out repair work in the summer (specifically, draining the coolant) often leads to a decrease in the service life.

In this case, everything depends on the financial side of the issue: if there is money to repair the heating system, choose bimetallic.

Otherwise, cast iron ones are also suitable.
