Bimetallic radiators Sira: technical specifications, reviews, installation

Bimetallic radiators from a popular Italian manufacturer in the market of heating equipment appeared not long ago, but despite this, have already won the recognition of the majority of consumers. For example, to date, radiators bimetallic Sira enjoy incredible popularity, which is due to their many advantages.

Description

The sections of the heating devices consist of a pair of steel channels (tubes) for the passage of the coolant, located vertically and flooded with aluminum high-quality alloy. As a result, a symmetrical and unified modern structure is formed relative to the center of gravity. The minimum contact surface of the aluminum alloy with the heat carrier and the absence of "pockets" in the heads of sections - sludge and gas collectors - minimizes the risk of gas formation and corrosion.

The originality of the design of the ends of the section allows, during their connection, the nipples to clamp the ring gaskets made of heat-resistant rubber inside the grooves, which ensures good tightness.

Advantages and design features

• Sira bimetallic radiators are characterized by an unusual design. The complete absence of sharp corners is perfectly combined with a gracefully curved shape. It is not only convenient, but also beautiful at the same time, which is confirmed by numerous reviews of consumers.
• These heaters are resistant to high pressure.
• Sira bimetallic radiators are characterized by good heat transfer.

The undeniable advantage of these devices is the ability to dock any number of sections. Low cost, efficiency, reliability, durability and quality are just a small part of the reasons why you should buy a radiator of this brand.

Bimetal radiators of heating Sira, in comparison with other heating devices, differ:

• Quiet operation and rapid heating.
• High heat output, thanks to a special combination of metals.
• Absence of welding seams.
• A long operational period, which, if used correctly, can be more than 25 years.

Specifications

Choosing equipment for heating, you need to know about the main characteristics that you need to pay attention to pick up devices that fully meet the requirements.

• Operating pressure. This parameter can be indicated in MPa or atm. It should be noted that 1 MPa = 10 atm. The Sira concurrent bimetallic radiator is designed for operation at an operating pressure of 16 to 35 atm. In this case, the pressure in the centralized heating system is no more than 15 atm., The autonomous - no more than 12 atm.
• Heat transfer (W). This parameter depends on the capacity of the heater, so when choosing these devices it is very important to give maximum attention to this.
• The center-to-center distance (mm) is the length measured between the lower and upper collector, and is 200, 300, 350, 500 and 800 mm.

Tips for choosing

To select the Sira bimetal heating radiators, it is necessary to take a responsible approach to calculating the required number of sections. Acquisition of heating appliances should be based on the heated area.

One section can be up to 2.4 kW. If problems arise during the calculation, you can always ask for help from specialists who will select the required number of sections, taking into account all requirements. If you are confident in your own abilities, then these calculations can be made independently.

Calculation

• If one wall leaves the room, there is one window opening and the ceiling height is 2.7 m, then a full heating of 1 m ² will be provided by a 100-watt unit.
• If there are two walls facing the street, there is one window opening, then for heating 1 m ^2, a 120 W radiator is required.
• If two walls go out into the street, there are two window openings and a ceiling height of 3 m, then for a 1 m ² heating a 130 W device will be needed.

Also, when calculating, it is important to remember that the screens for the heating radiator reduce the heat transfer of the heaters.

Installation

Bimetal radiators can be installed in heating systems with copper, steel and polymer pipelines.

To achieve design heat transfer during installation, the following optimum distances should be adhered to:

• Not less than 100 mm to the window sill.
• Not less than 30 mm to the wall.
• At least 100 mm before the floor construction.

In order to protect the elements of the heating system from corrosion and the deposition of hardness salts (which is typical not only for boilers, pipelines, but also for radiators, irrespective of the material from which they are made, whether it is cast iron, steel or aluminum), it is recommended to add to the circulating liquid Special reagents based on aliphatic polyamines. The approximate consumption is: for 200 liters of water, 1 liter of reagent.

For each radiator the bimetallic Sira 500 or any other is recommended to install a manual or automatic vent valve. It is very important, when installing the valve, to make sure that the heater is disconnected from the common system.

It is strictly forbidden to disconnect the appliances from the heating system (to block both locking devices at the inlet and outlet), except for the cases of their dismantling and maintenance.

It is not allowed to draw water from the heating system.

Also, the work of heating devices on the water from the hot water supply system is strictly prohibited.

It is extremely undesirable to install radiators in heating systems, where the role of the coolant is a waste fluid from technological processes, which contains aggressive components in its composition.

It is forbidden to directly draw water into the heat network from the hot water supply without preliminary qualitative water treatment.

Cost

The approximate average cost of the heaters of this brand is indicated in the table below. At the same time, there are proposals where the bimetal radiators Sira RS cost from 379 to 813 rubles per section. It is also worth noting that the price is constantly changing depending on the market situation and season.

Customer Reviews

Radiators bimetallic Sira, despite the good heat dissipation, are of low cost. All models of this manufacturer are designed taking into account the peculiarities of our climate. During the operation of bimetallic radiators, the manufacturer guarantees that the radiators are able to withstand the working pressure in the heating system up to 40 atm. For this reason, we can say with confidence about the high reliability and excellent quality of this product.

Also it is worth paying attention to that, by studying the reviews about these radiators, you can find a lot of positive information about the fact that these heaters are distinguished by a modern and exquisite design. That allows them to be installed in residential premises regardless of their design. And thus it is absolutely not required in addition to get special screens for a radiator of heating.
