Bimetallic radiators : choose the best model

What requirements must meet the heating radiator

When it comes to buying and installing a new heating equipment in the apartment or a country house, the first selection criteria that come to mind are simple and clear.Feedback from consumers they can be reduced in five main groups.

We did not withdraw the rating of consumer preferences, so the most common requests arranged in random order.The ideal heater must:

• provide a comfortable temperature at any fluctuations and failures in the heating networks;
• be resistant to mechanical deformation and seal failure during hydraulic tests;in other words, do not occur when thermal networks put on the verification seasonal;
• work flawlessly indefinitely, or at least fifty years;
• have a modern and stylish design that fits easily into any interior urban apartments and country houses;
• sold at a reasonable (preferably low) price, which can be chosen in a wide model range.

In our opinion, these needs are most able to meet the bimetallic radiator, but it's better to choose it in the vast market deliberately and prudently.

design and advantages of bimetallic radiator

Bimetallic radiators have already confirmed their best performance, it is necessary to understand, due to what they have achieved and how to use them correctly.Structurally, this battery is a hybrid of the radiator and convector.

The coolant is supplied to the battery for steel tubes (horizontal manifolds and vertical jumpers) and gives off heat to the convective zone and aluminum casing of bimetallic radiator.High mechanical strength of steel welded joints, in contrast to the pure aluminum radiators ensures the reliability of the device under test pressure up to 35-40 atmospheres, the excess thermal conductivity of aluminum allows you to remove up to 80% of the supplied heat.A little more positive:

• aggressive chemically unstable heat transfer fluid is not in contact with aluminum surfaces, so the lifetime of bimetallic radiator heating system depends on the quality of welding inner tubes;
• relatively small weight (only 50% greater than that of pure aluminum) ensures easy transportation and installation;
• low thermal inertia allows a good automation quickly adjust the room temperature mode;alas, it is here and found the lack of a bimetallic radiator: fast jet heating, cooling of the battery and, as a consequence, the short life of thermostatic equipment;
• high heat and the housing area of ​​bimetallic radiator, which provides for equal parameters of the working fluid heating a larger area of ​​residential premises.

Rating bimetallic radiators

note that the objective of the evaluation is not high, because bimetallic radiators evaluate what is best on the basis of customer reviews, blog and Internet data - sales is not entirely correct.However, the five most popular models invariably includes the following heating devices in its class.

• RIFAR Monolit (Russia): the working and test pressure 40/60 bar (very high figure);section sizes 577h80h100 mm heat - 196 kW, price per section - 610 rub .;the main advantage - the lack of intersectional junctions and reliability.
• Global Style Extra 500 (Italy): -50 cm spacing, pressure - 35 atmospheres, coolant temperature - up to 110 degrees, the price for the section of the radiator - 740 rubles..This great design and quality of the surface treatment.
• RoyalThermoBiLinerInox (Italy) - with an average price (570-590) in the bimetallic heating radiators from this manufacturer, pipe anti-corrosion properties in contact with the cooled zone can be considered the best.
