How to choose and what to pay attention to?

  • Monolithic is better in terms of characteristics: even strong water shocks are not terrible for it, it can withstand the huge pressure of the coolant, there can be no unpleasant leaks between the blocks, and its service life — just imagine! — 100 years old. However, you will not be able to reduce or add sections at will, and the price tag for such models will be very high.
  • Sectional sections are cheaper and allow you to choose the number of sections yourself.
  • The standard distance between the lower and upper collector is from 200 to 800 mm.. Sizes starting from 800 mm need to be ordered individually, and 200 mm ones are rarely found on the market.
  • When choosing a company, it is important not to lose money. The most reliable ones are the following: Royal, Global, Rifar, Sira, and STOUT. It should be remembered that European brands are distinguished by high quality materials and Assembly, but they can not always be adapted to Russian heating networks.
  • For some models, the frame consists entirely of steel, for 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 second ones have higher heat transfer and lower cost.

Types of bimetallic radiators

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

Joints are sealed with gaskets made of heat-resistant rubber.

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

The heat exchange area is large. Monolithic, i.e. solid, structures can withstand much higher hydrostatic pressure and last longer (up to 50 years).

One section is capable of delivering 100-200 watts.

Cases in such models are cast entirely, then pressure treatment and applying a layer of aluminum to the steel frame. They are more expensive than sectional ones.

Advantages and disadvantages of bimetallic radiators

Dignities:

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

Disadvantages:

  • 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 slightly smaller than its analogues, which reduces heat exchange (but not much).
  • The hydraulic resistance is higher, which means that more power is required to pump water through the system.

Which company should I choose?

The most popular ones on the modern market are:

  • Italian: Fondital, Global, Sira, Royal Thermo. Italy is the birthplace of bimetallic radiators, and still stands out among competitors with the ability to create not just a high-quality, but also an aesthetically attractive product. The section costs about a thousand rubles, design developments are much more expensive, but you can also fit such a radiator into any, even the most “sophisticated”, interior.
  • Russian: Rifar, STOUT. A high place in the world ranking is occupied due to the applied method of contact-butt welding 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 companies. Excellent value for money.

Aluminum or bimetallic radiator – which is better?

Aluminum ones:

  • do not have a core;
  • they are made of the same metal;
  • heat transfer is 15-20% higher;
  • they have less weight and are easier to install;
  • serve for 20-25 years;
  • if the pH level in the water rises, corrosion occurs, but gradually
  • they thin out and start leaking;
  • they are unstable to high pressure;
  • they do not tolerate the lack of coolant at the time of its discharge.

Bimetallic:

  • dear ones;
  • operation is also possible at high humidity temperatures;
  • they can withstand pressure up to 24 atmospheres;
  • the quality of the heat carrier (pH fluctuations and unfavorable environment) is practically independent;
  • staunchly take a hammering;
  • resistant to corrosion;
  • if air gets into the pipe, rust will appear;
  • they are plastic.

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

Steel or bimetallic-what should I choose?

Steel batteries have quite a few fans. And this is not surprising: they look stylish, easy to install, and have above-average heat transfer.

The cost is also low. However, the parameters of the working pressure are so low that they cannot withstand water shocks, even of medium power (only the working pressure of the boiler room can “shoulder” them), 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.

Bimetallic units do not interfere with a barometric load of up to 40 ATM, so they are not afraid of pressure surges. They warm better than others, practically do not accumulate lime on the walls, they are light, they serve for a long time.

You can compose sections and select the desired number.

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

Construction companies also prioritize steel ones, as they are cheaper.

Cast iron or bimetallic – which one should I choose?

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

Bimetallic units are more modern in appearance, reliable and easy to install.

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

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