What Bimetallic radiators better - sectional or monolithic, true or bimetallic polubimetallicheskie
Bimetallic radiators - are placed without any problems, give plenty of heat, and can boast of beautiful design.The stores sell different in design and specifications Bimetallic radiators, but which ones are best to buy, find out in this article, analyzing their key parameters and design features.

What is the difference and polubimetallicheskie Bimetallic radiators?
In these bimetallic radiators made of aluminum only the outer part.Radiators are manufactured as follows: pipe welded steel core, and then they pour aluminum under pressure.As a result, the coolant contacts only with the steel, without touch
do and radiators, the core of which is not made of steel and copper.It is a real salvation for the autonomous heating systems, where water is added to antifreeze.After all steel pipes a coolant quickly ruin.
have polubimetallicheskogo radiator core consists of two metals.Vertical channels it reinforced steel elements, but the horizontal - aluminum.By increasing the amount of aluminum in the product increases the heat transfer of a radiator.However, hot water with a high alkali content (in the central heating), contacting this aluminum corrodes.And again, a different thermal expansion of aluminum and steel parts of the core may cause their displacement, leading to an unstable radiator.
Usually bimetallic radiators are installed in homes with central heating system.In such systems, there are two big problems - a high pressure with occasional irregular and low-quality coolant.Both will have a sufficiently large negative impact on the radiators polubimetallicheskogo type.
So once you have decided to install reliable heating devices, it is better to give preference to true bimetallic radiators.Polubimetallicheskie models of radiators can be found at companies such as: Sira, Rifar, Gordi.They differ substantially from the price of bimetallic, but they are worth.
Sectional Bimetallic radiators or monolithic
At first bimetal products have always been collected from several sections.However, any sectional radiators can suffer from heat-carrier, damaging the joints and reduces the life of the instrument.In addition, the joints are always potentially dangerous place, which is the most exposed to leakage due to high pressure in the system.So we come up with a new technology, which is made of solid steel or copper collector, and on top of it "wears a shirt" made of aluminum.These radiators are called monolithic.
device bimetallic radiator section.
Now let's try to figure out what is best bimetallic radiators - sectional or monolithic.The technical characteristics of the advantage of the latter is obvious.
- Shelf life - up to 50 years (from section - up to 20-25 years).
- Operating pressure - up to 100 bar (at the section - up to 20-35 bar).
- Thermal output per section - 100-200 watt (on par with the sectional models).
But the price of monolithic devices is slightly higher than the sectional.The difference can be up to one-fifth.And one more thing: a model with a solid core can not be modified by removing unnecessary or add additional sections, but they are available in various sizes in height and length.Therefore, choose the required radiator power is not difficult.
If the apartment is in a high-rise building, whose height exceeds 16 floors, it can be assumed that the pressure of the coolant will be significant, so in this case there is a need to give preference to a monolithic model.
What better company Bimetallic radiators
begin with Italian manufacturers.First of all, a company Sira, whose specialists have been invented and bimetal radiators.You can also mention the brand and Global Style Radena.All these products have a price for the section from 700 to 1500 rubles.The elegant and high-quality finish, interesting design, compact and easy - that's what the radiators from Italy.Modern technology allows them to work no less than 20 years.Specifications:
- Sectional heat capacity - from 120 to 185 watts;
- limit hot water temperature - 110 degrees;
- operating pressure - 35 bar.
Do not forget about the domestic manufacturers.One of the most famous is Rifar.Et company from the Orenburg region produces thermal devices with price from 500 to 900 rubles per section.Specifications:
- Sectional heat capacity - from 100 to 200 watts;
- limit hot water temperature - 135 degrees;
- operating pressure - 20 bar.
note patented radiator RIFAR MONOLIT, which is often called one of the best home appliances.He tested at a pressure of 150 bar.Specifications:
- Sectional heat capacity - from 134 to 196 watts;
- limit hot water temperature - 135 degrees;
- working pressure - up to 100 bar.
It may be noted radiator South Korean company MARS.The core does not have steel and copper.Price - from 400 rubles per section.Performance Claims:
- limit hot water temperature - 130 degrees;
- operating pressure - 20 bar;
- sectional heat - 167 watts.
Polish company «REGULUS-system» also manufactures bimetallic radiators with a copper core.The manufacturer guarantees 25 years.Specifications:
- Operating pressure - 15 bar;
- limit hot water temperature - 110 degrees.
Well, a few words should be said about the Chinese producers.These radiators are significantly less well-known brands, because they do not shine careful finish and beautiful design.In principle, the presence of a very modest budget, you can take and "Chinese", given that it could withstand less pressure.
