Sira brand radiators are produced in an Italian company using the latest generation European equipment. The interest of domestic consumers is due to the fact that the batteries are suitable for all types of heating systems and are adapted to work in different climatic conditions. Manufacturing technologies are based on the principles of low energy consumption and ensure high performance characteristics of the devices. Due to the design features, Sira products have high heat transfer and, if installed correctly, do not require replacement or major repairs for a long time.
Description of models
The manufacturer offers extruded and cast aluminum batteries, electric and bimetallic radiators. The devices are equipped with two steel channels through which the coolant moves. The absence of voids eliminates the accumulation of debris and gas deposits, leading to corrosion. In total, the company presents more than 30 models:

Heavy
Disadvantages:
Poor quality painting
Comment:
While I was installing it, everything was peeling off. Moreover, the old battery with which this one was spliced was not damaged, but on this one the paint is falling off in flakes. Buy at a discount

Step-by-step instruction
- First of all, it is necessary to make markings for the subsequent installation of brackets.
- Then the brackets are fixed to the wall.
- Mayevsky taps are installed on the radiators.
- After that, heat supply regulators, plugs, valves and taps are installed.
- Horizontal alignment of heating devices placed on brackets is carried out.
- Using transition fittings, radiators are connected to the pipeline system.
- Finally, the heating system is pressure tested and the coolant is pre-started.
In practice, the efficiency of even a high-quality heating system decreases over time. In this regard, the owner often faces the problem of replacing its individual components.
To change or install radiators, you do not need to have any special skills; you just need to follow the step-by-step instructions, have the appropriate tools and at least have a little understanding of the specifics of this area.

Sergey Sh. ★
Advantages:
I liked the appearance after reading the reviews, looking at the pictures on the Internet, and even when they delivered everything was fine.
Disadvantages:
When they installed the heating, it was turned off, but when it was turned on, the radiator began to leak and flowed so that a puddle formed.
No guarantee promised works, I contacted the manufacturer and they sent me to the seller. The seller gave me a warranty card and a stamp on it, but there is no guarantee signature. The warranty conditions were stated as follows: dismantle the radiator at your own expense, take it across Moscow for repairs at your own expense. I do not advise you to contact this manufacturer, it is not clear who sells their radiators and how, there is no guarantee, then you will suffer with dismantling and transportation to the repair site, and it is not a fact that after a while it will not leak again. Before this, domestic radiators were installed in another apartment and there were no such problems Alexander ★★★★★ Advantages:
Experienced plumbers recommended these batteries. 8 sections in the 15th room of a panel house at -12 heat very well.
You have to turn off the battery. They look very good. Disadvantages:

Sectional bimetallic radiator Sira Ali Metal 500 reviews
Dmitry B. ★★★★★ Advantages:
Price.
Full bimetal, 190 watts per section, 95mm section depth, 5 wide and thick ribs, well painted, smooth joints between sections. Mine is made in Italy (it says on every section). Comment:
It looks like this is the most affordable full-bimetallic European radiator at a price slightly more expensive than the worst one in China. It’s strange that it’s only on the website for Russia, apparently specifically for our bad water. Buy at a discount
Global
The Global brand was founded in 1971 by the Fardelli brothers.
At the beginning of its activity, the company produced only aluminum radiators. In 1994, the company successfully began to conquer the Russian market and then they had to start producing bimetallic batteries. The equipment produced by Global meets Russian GOST standards. Modern radiators produced by a company from Italy are made of high quality materials. There are steel vertical and horizontal tubes inside. The outer part of the radiator is aluminum, which indicates high strength.

Innovation and Design
Onice design and technology are the result of many years of research and innovation, searching for new solutions for living spaces. The exterior characteristics of Onice set a benchmark for the entire industry, representing one of the most modern examples of Italian style in industrial design. Its exclusive lines, smooth and dynamic, make it suitable for any space, making it the ideal piece of furniture for the most modern and prestigious spaces.
The new ergonomic concept electronic display has been designed to provide the best intuitive user experience, together with comprehensive temperature control and usage scheduling. Its locking system provides additional safety for the elderly and children, who are thus protected from the possible consequences of incorrectly set parameters.
Installation
The installation of a bimetallic radiator is carried out by two people, strictly horizontally. Distortions in the installation lead to uneven heating of the sections.
The work is performed in the following order:
- Installation of fasteners. Standard brackets are used, which are secured to dowels. To do this, holes are drilled in the wall using a hammer drill.
- The radiator is suspended on brackets, with hooks running through the space between the sections. The horizontal position is carefully checked using a building level.
- Ball valves and a Mayevsky valve (air valve) are installed.
- Connection to the central heating main. The joints are carefully sealed.
- System testing. The return valve opens no more than 2/3 to prevent water hammer. The system is filled with liquid and the tightness of all elements is checked.
Installation rules:
- The lower part of the battery is raised above the floor to a height of 6-7 to 10-12 cm to optimize convection flows.
- The upper cut should not be closer to the window sill than 5-6 cm.
- Install the battery in the middle of the window.
- Radiators in different rooms are mounted at the same height.
Important! Painting a bimetallic radiator impairs heat transfer. When cleaning the panels, do not use abrasives, which can scratch the aluminum.
Life time
The most important indicator of any household equipment is service life or durability. This parameter largely depends on the materials used and build quality. Trusted manufacturers guarantee that their products will last at least 20 years. Adaptation of devices to Russian conditions, characterized by instability of parameters and pressure surges, becomes important. Adapted Russian-made batteries can operate reliably for 30-35 years
Bimetallic radiators for central heating in apartments are a step in the right direction. With the right choice of a high-quality device and proper installation, they can provide comfortable conditions in a living space. It is important to realistically assess the required heat transfer power. Only trusted domestic and foreign companies can guarantee the proper quality of radiators.
How they work
The difference between bimetallic radiators and other types of batteries is the combination of steel pipes with aluminum panels. The steel pipe ensures the movement of coolant under pressure due to its strength, and aluminum, which has high thermal conductivity, increases the transfer of thermal energy to the environment.
The following bimetallic batteries are currently produced:
- Fully bimetallic construction. All of her steel pipes are surrounded by aluminum. Only steel has direct contact with the coolant, through which heat is transferred to the aluminum panels. This type is durable and reliable.
- Semi-bimetallic construction. In such radiators, only the vertical, most mechanically loaded, pipes are made of steel. Part of the line is made of aluminum; in these areas the coolant is in direct contact with it. The cost of such batteries is noticeably lower and has more efficient heat dissipation, but they are less durable.
According to the design, there are 2 types:
- Sectional radiators. This is the most popular type. First, non-separable sections are made, which are connected to each other with nipples in production conditions. You can disconnect and, conversely, add sections.
- Solid batteries. They have a monolithic design, and therefore have their own dimensions and power. Due to the lack of joints, the batteries are very durable. The choice depends on conditions and finances. Often you have to choose between durability, cost, and appearance.
