Sira heating radiators are manufactured by the world famous Italian manufacturer Sira Group and rightfully occupy a leading position in many countries of the world. High recognition was obtained due to the high quality of the equipment manufactured in combination with an acceptable cost. The company was founded in 1959. She became the creator of bimetallic radiators.
Characteristics of heating radiators Syrah
Sira radiators have a modern design solution, due to which the level of heat transfer is increased and various operational characteristics are improved. The structure of the heat exchangers is ribbed and sectional, which allows you to choose the most suitable models for the heated room.
Heating equipment is produced in different color and design solutions, which will allow you to fit as well as possible into the design of the room. The consumer can purchase one of two types of batteries produced by an Italian company:
- bimetallic;
- aluminum.
Thanks to the unique production technology, it was possible to combine incompatible metals in each bimetallic radiator. Inside each section contains steel, which directly comes into contact with the coolant, the generated heat is supplied to the aluminum housing. The owner of such equipment will not face the problems of corrosion and alkali. The resistance of the working pressure reaches 40 atmospheres, the designs are easy to install, quickly and evenly heat the room. The manufacturer claims the durability of the batteries, the minimum warranty from them is 20 years.
Aluminum batteries are produced by extrusion technology, which involves the use of plastic alloys in each section and two collectors brazed together under high pressure. Such design features allow the equipment to withstand pressure up to 25 atmospheres.
Aluminum radiators are easy to install and economical to use, an additional advantage is that you can purchase equipment up to two meters high.
Models of bimetal radiators Sira
Sira gladiator
This type of heating equipment is considered the most budgetary in comparison with analogues.
Specifications:
- power is 92 W;
- dimensions: center distance - 200 mm, depth - 80 mm, height - 275 mm;
- the most admissible working pressure - 30 atmospheres.
Externally, this model has an interesting design. The minimum cost of each section is 530 rubles.
Sira R.S. Bimetall
Battery sections Sira R.S. Bimetall have the following dimensions: height - 372 mm, depth - 95 mm, width - 80 mm. The compactness of the radiators allows them to be installed in rooms with a small area. Sectional assembly is carried out only in an even amount. If desired, the distribution company will be able to fulfill an individual order. The maximum number of sections should not exceed 20 pieces.
Specifications:
- center distance reaches 300 mm;
- heat transfer - 142 W;
- the ability to connect batteries to any heating system, the acidity of the coolant which ranges from 6.5 to 9 pH;
- the most admissible working pressure - 40 atmospheres.
The surface is painted with powder enamel of the highest quality. The price of the section is approximately 750 rubles.
Sira concurent
This is the latest and newest radiator model from Syrah. This line is presented only by one model - Syrah Competitor 500.She absorbed all the best qualities of her predecessors.
Specifications:
- dimensions: center distance - 500 mm, width - 80 mm, and height - 565 mm;
- thermal return of each section - 190 watts.
An interesting design allows you to harmonize with the interior of the room and provides additional thermal return. The cost does not exceed 630 rubles in the domestic market.
Aluminum Battery Models
Sira nik
These radiators are designed to heat apartments and country houses. Thanks to innovative technical development, sections can be connected to various heating systems. They are able to withstand up to 25 atmospheres.
All models have a width and height of 80 * 80 mm, the number of sections ranges from 4 to 12 units. The surface is painted with the highest quality paint using polymer segments. The minimum warranty from the manufacturer is 15 years.
Radiators can be connected to heating equipment, the maximum heat of which does not exceed 110 degrees, and the acidity ranges from 7-7 pH.
The cost of Sira NIK is very democratic on average is 320 rubles.
Sira alux
A characteristic feature of this series is a large heat transfer, due to which Syrah Alyuks is able to heat rooms with a large area. The price of one section division in the domestic market is approximately 420 rubles. They are released in three variations:
- Sira Alux 200 - heat transfer 97 W;
- Sira Alux 350 - maximum power is 150 watts;
- Sira Alux 500 - 190 W thermal output.
All other technical parameters are identical to Sira NIK.
Advantages and disadvantages of the manufacturer
The main advantage of Syrah is the high quality of its products. In the manufacture of modern technological equipment and the latest developments are involved. Other advantages of radiators from the Italian manufacturer:
- attractive appearance;
- green production;
- high quality processing without burrs and sharp cuts;
- long service life - up to 50 years;
- surface painting with epoxy enamel;
- profitability;
- in the manufacture of materials with high thermal conductivity, which provides quick heating;
- resistance to corrosion;
- prefabricated sectional device.
The disadvantages include the relatively high cost of equipment, as well as an inconvenient size range. The width of most models is not more than half a meter.
Power calculation
Many people have difficulty calculating the power of batteries for heating their living space. For this, the general rule of heat production of radiators should be used, taking into account the region of residence and the area of the room.
On average, for every 10 sq.m. necessary:
- for the southern regions - 900 W;
- for the middle band - 1000-1500 W;
- for the north - 2000 watts.
To calculate the required number of sections, the area of the room is divided by the heat transfer coefficient of each unit and the resulting number is multiplied by 100.
For heating private apartments, it is preferable to use bimetallic radiators, and it is better to install aluminum batteries in country cottages.
