Sira heating radiators are produced 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 produced, combined with an acceptable cost. The company was founded in 1959. She became the creator of bimetallic radiators.
Characteristics of Syrah heating radiators
Sira radiators have a modern design solution, due to which the level of heat transfer is increased and various performance 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 colors and designs, which will allow you to fit into the design of the room as well as possible. The consumer can purchase one of two types of batteries produced by the Italian company:
- bimetallic;
- aluminum.
Thanks to the unique production technology, it was possible to combine incompatible metals in each bimetallic radiator. Inside each section, steel is contained, which directly comes into contact with the coolant, the heat generated is fed into the aluminum housing. The owner of such equipment will not face the problems of corrosion and alkali formation. Working pressure resistance reaches 40 atmospheres, structures 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 using extrusion technology, which implies the use of ductile alloys in each section and two collectors welded together under high pressure. Such design features allow the equipment to withstand pressures up to 25 atmospheres.
Aluminum radiators are easy to install and economical to use, with the added benefit of being able to purchase equipment up to two meters high.
Sira bimetallic radiator models
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 maximum allowable working pressure is 30 atmospheres.
Externally, this model has an interesting design. The minimum cost of each section is 530 rubles.
Sira R.S. Bimetall
Sira R.S. battery sections Bimetalls 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 number. If desired, the distributor will be able to fulfill an individual order. The maximum number of sections should not exceed 20 pieces.
Specifications:
- the center distance reaches 300 mm;
- heat transfer - 142 W;
- the ability to connect batteries to any heating system, the acidity of the coolant of which ranges from 6.5-9 pH;
- the maximum allowable working pressure is 40 atmospheres.
The surface is painted with the highest quality powder enamel. The section price is approximately 750 rubles.
Sira concurent
This is the latest and newest model of radiators from the manufacturer Syrah. This line is represented by only one model - Syrah Competitor 500. It has incorporated all the best qualities of its predecessors.
Specifications:
- dimensions: center distance - 500 mm, width - 80 mm, and height - 565 mm;
- heat output of each section - 190 W.
The interesting design allows it to be in harmony with the interior of the room and provides additional heat output. 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, the sections can be connected to various heating systems. They are capable of withstanding 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 manufacturer's warranty is 15 years.
Radiators can be connected to heating equipment, the maximum heating of which does not exceed 110 degrees, and the acidity ranges from 7-7 pH.
The cost of Sira NIK is very affordable, on average 320 rubles.
Sira Alux
A characteristic feature of this series is high heat transfer, thanks to which Syrah Alux is able to heat rooms with a large area. The price of one sectional division in the domestic market is approximately 420 rubles. They are released in three variations:
- Sira Alux 200 - heat dissipation 97 W;
- Sira Alux 350 - maximum power is 150 W;
- Sira Alux 500 - 190 W heat output.
All other technical parameters are identical to the Sira NIK.
Manufacturer's advantages and disadvantages
- attractive appearance;
- environmentally friendly 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 are used, which ensures rapid heating;
- corrosion resistance;
- 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 no more than half a meter.
Power calculation
On average, for every 10 sq. it is necessary:
- for southern regions - 900 W;
- for the middle band - 1000-1500 W;
- for the north - 2000 W.
To calculate the required number of sections, the area of the room is divided by the heat transfer rate of each unit and the resulting number is multiplied by 100.
For heating private apartments, it is preferable to use bimetallic radiators, and in country cottages it is better to install aluminum batteries.
