For the domestic consumer, the Sira trademark has long been a guarantee of reliability and long service life. The secret of such popularity is simple - quality, adherence to technology and service. That is why Sira heating radiators are chosen to complete systems for maintaining a comfortable temperature: bimetallic and aluminum. What are their design and operational features?
The quality and reliability of Sira radiators
The history of the company began over 50 years ago. Initially, she specialized in the manufacture of cast aluminum structures. Then it was decided to start production of its own products - Sira heating batteries.
The specificity lies in strict adherence to the manufacturing technology. For this, technological schemes have been developed, which are checked at each stage of production. The result of this work is reviews of Sira heating radiators, in which their functionality and compliance with the declared parameters are noted.
Currently, the corporation can offer customers the following types of radiators:
- Bimetallic and hybrid;
- Aluminum - cast and extrusion;
- Steel electric batteries;
- Heated towel rails.
In addition, it should be noted that each model of the radiator, before going on sale, is tested for joint operation with all types of boilers - from solid fuel to modern condensing boilers. At the same time, the distinctive features of the Sira aluminum heating radiators and their bimetallic counterparts are taken into account. This is fully reflected in the company's product range.
It is best to use radiators of the same model to complete the heating system. Otherwise, a different heat transfer coefficient will affect the efficiency of the system.
Sira bimetal models
The flagship of sales is currently the Sira bimetal heating radiators. During the development of their design, the shortcomings and problems arising during operation were taken into account.
At first glance, their appearance is no different from similar products of other brands. The main feature of Sira bimetallic heating radiators is the absence of welding seams. Each section is made by casting at our own production facilities. This greatly reduces the likelihood of leakage when the maximum pressure is exceeded. It is the welding seams that are often the "weak point" - the cause of the leakage of the heating batteries.
In addition, the following features of Sira heating batteries should be noted:
- Small volume of coolant. It is distributed along the channels of the structure, providing quick heating of the battery;
- The configuration of the outer fins of the heating section facilitates optimal air convection. Lack of sharp corners;
- The coolant channel is made of a special stainless steel alloy. It is almost completely protected against corrosion. Sira rs 500 heating radiators have this characteristic.
An innovative solution was the appearance in the range of a unique battery model - RS Twin. Its design provides for the possibility of heating both from a standard heat carrier (water, antifreeze) and using a built-in heating element.
The performance data (power) is given by default for a thermal setting of 80/60. With low temperature heating, the battery rating will be less.
Sira rs bimetal
Bimetallic batteries are considered the most reliable and durable. These include models of heating radiators Sira rs 500, where the last digit indicates the center distance. The company markets them as premium batteries. To install, you should know some technical data:
- Connection diameter - 1 ”;
- Each section is 80 mm wide;
- The maximum allowable working pressure is 40 bar.
In reviews of Sira rs 500 heating radiators, the importance of installing the correct piping is often mentioned. Its main element is a thermostat.
The average cost of one section is 1155 rubles.
Sira Gladiator
To complete heating with more affordable batteries, the company offers a line of models of the Gladiator series. According to external data, they are almost completely identical to the RS Bimetal. The difference lies in slightly worse technical characteristics. In particular, the heat transfer coefficient is less than that of RS.
One section of the Sira Gladiator bimetallic heating radiator currently costs from 720 rubles.
Self-connection of battery sections is not recommended. For this, special equipment is used to ensure good pressure testing of mounting assemblies.
Sira aluminum radiators
Sira aluminum radiators are manufactured using welding technology. Water supply channels are formed after connecting 2 parts of the structure into one whole. This technique leads to a lower value of the maximum allowable pressure - up to 16 bar.
Unlike the Sira rs 500 series heating radiators, which are unpretentious in terms of operating conditions, it is recommended to install aluminum models in autonomous systems with pressure stabilization. Central heating is characterized by periodic surges in pressure, which often leads to a water hammer. Not always the aluminum structure can withstand such exploitation.
It is important for the consumer to take into account the following qualities of these radiators:
- Affordable cost. If we compare by this indicator, Sira heating radiators bimetallic and aluminum - the latter will be 15-20% more expensive;
- Increased heat transfer;
- Periodic flushing is required to prevent rust.
A novelty in the company's assortment is the Sira heating radiators made of aluminum from the Ali Princess and Ali Queen series. Their design features external fins for air convection. They are directed towards the room, which ensures an even distribution of heat throughout the room.
The maximum number of sections recommended for installation is 15. For optimal heat transfer, the manufacturer advises to mount radiators, which consist of at least 4 sections. The average cost of each of them is 550 rubles.
Sira kits are recommended for fixing radiators. They are designed for a specific type of battery.
All Sira radiators are powder coated white RAL 9010. Therefore, if you need to repaint the surface, you cannot remove the factory layer. For this, it is best to use special paints.
