How to choose and what to pay attention to?

• Monolithic is better in characteristicsEven strong water hammer it is not afraid of, it withstands a huge pressure of the coolant, there can be no unpleasant leaks between the blocks, and its service life - just imagine! - 100 years. However, you will not be able to add or decrease sections at your will, and the price tag of such models will be very high.
• Sectional is cheaper and allows you to choose the number of sections.
• The standard distance between the lower and upper collector - from 200 to 800 mm. The size of 800 mm and more must be ordered individually, and the 200-millimeter are rarely found on the market.
• When choosing a company, it is important not to miscalculate. The most reliable are considered the following: Royal, Global, Rifar, Sira, STOUT. It should be remembered that European brands are of high quality of materials and assembly, but can not always be adapted to the Russian heating systems.
• Some models have a frame made entirely of steel, while others only have steel reinforcements for the channels through which the boiling water flows.. The first option is more reliable and of higher quality, such radiators do not leak and do not suffer from corrosion. But the latter have a higher heat output and less cost.

Types of bimetallic radiators

According to the design of radiators are divided into sectional and monolithic. The sectional ones allow the customer to choose the number of sections by himself.

The joints are sealed with rubber gaskets of heat-resistant rubber.

Require a special mode of operation, because the joints of the components are destroyed over time.

The area of heat transfer is large. Monolithic, i.e. one-piece, structures withstand much more hydrostatic pressure and last longer (up to 50 years).

One section is able to produce 100-200 W..

Bodies in such models are cast as a whole, then comes the processing of pressure and the application of a layer of aluminum on a steel frame. Are more expensive than the sectional.

Advantages and disadvantages of bimetallic radiators

Advantages:

• Good heat transfer and the maximum working pressure.
• Reducing the quality of the coolant is not a problem for them.
• The service life of such units - several decades.
• Due to the steel core, the system is not affected even by strong hydraulic shock.
• Corrosion processes for bimetallic radiators are not afraid.
• The response of such a thermostat is very fast.
  They look very attractive externally: they are not made in the boring white color, but in a colorful range, and on top are also covered with an additional protective layer.
• It is very easy to install them, thanks to the well-thought-out system of connections.

Disadvantages:

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

What company to choose?

The most popular in the modern market are:

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

Aluminum or bimetallic radiator - what is better?

Aluminum:

• Do not have a core;
• are made of one metal;
• Heat output is 15-20% higher;
• They weigh less and are easier to install;
• lasts 20-25 years;
• If the pH level in the water rises - corrosion occurs, the walls gradually
• they become thinner and leak;
• They are unstable to high pressure;
• they do not tolerate the absence of coolant at the moment of its drainage.

Bimetallic:

• expensive;
• operation is possible even at high temperature of humidity;
• they withstand pressure up to 24 atm;
• practically do not depend on the quality of the heat-carrier (pH fluctuations and unfavorable environment);
• are resistant to water hammer;
• resistant to corrosion;
• If air gets into the pipe - there will be rust;
• plastic.

In a multi-storey building it is better to put bimetallic.

Steel or bimetallic - what to choose?

Steel radiators have many fans. And no wonder: they look stylish, easy to install, have a heat output above average.

The cost is also low. However, the parameters of the working pressure is so low that they do not withstand water hammer, even of average power (only the working pressure of the boiler room they "can do"), and corrosion is exposed.

In addition, they are not covered with protective paint coating outside, which means - no protection against rust on the outside they have.

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

Sections can be assembled and choose the right quantity..

As can be seen, the first and second sections have the same advantages. If a buyer has money, he would prefer to choose bimetallic radiators.

For construction companies, steel radiators are a priority, because they are cheaper.

Cast iron or bimetallic - which one to choose?

Cast iron - a classic, popular back in Soviet times. It cools down for a long time (and transfers heat longer), it is resistant to aggressive liquids and abrasive particles, it can be painted as you like. But it will take a long time for the cast-iron radiator to warm up properly.

Bimetal units have a more modern appearance, are reliable and easy to install.

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

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

In the rest - cast iron will also do.
