For domestic consumers, the Sira brand has long been a guarantee of reliability and a long service life. The secret of such popularity is simple - quality, adherence to technology and after-sales service. That is why, to complete systems for maintaining a comfortable temperature, Sira heating radiators are chosen: bimetallic and aluminum. What are their design and operational features?
Quality and reliability of Sira radiators
The history of the company began more than 50 years ago. Initially, she specialized in the manufacture of cast aluminum structures. Then it was decided to start production of our own products - Sira heating radiators.
Specificity lies in strict adherence to manufacturing technology. For this, technological schemes have been developed that are tested at each stage of production. The result of this work are 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;
- Towel dryers.
In addition, it should be noted that each radiator model is tested for joint work with all types of boilers before it goes on sale, from solid fuel boilers to modern condensing boilers. At the same time, the distinctive features that Sira aluminum radiators and their bimetal analogues have are taken into account. This is fully reflected in the product range of the company.
To complete the heating system, it is best to use radiators of the same model. Otherwise, a different heat transfer coefficient will affect the efficiency of the system.
Bimetal models Sira
The flagship of sales at present are Sira bimetal heating radiators. During the development of their design, the disadvantages and problems encountered 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 bimetal heating radiators is the lack of welds. Each section is made by pouring at its own production facilities. This significantly reduces the likelihood of leakage when exceeding the maximum pressure. It is the welds that are often the "weak" place - the cause of the leakage of the heating batteries.
In addition, it should be noted such features of Sira heating batteries:
- A small amount of coolant. It is distributed along the channels of the structure, providing fast heating of the battery;
- The configuration of the outer fins of the heating section contributes to optimal air convection. Lack of sharp corners;
- The coolant channel is made of a special stainless steel alloy. It is almost completely protected from corrosion. This characteristic has Sira rs 500 heating radiators.
An innovative solution was the appearance in the assortment of a unique battery model - RS Twin. In its design, it is possible to heat both from a standard coolant (water, antifreeze) and using the built-in heating element.
Performance specifications (power) are given by default for 80/60 thermal conditions. With low temperature heating, the rated battery power will be less.
Sira rs bimetal
Bimetallic batteries are considered the most reliable and durable. These include models of Sira rs 500 heating radiators, where the last digit indicates the center distance.The company positions them as premium batteries. For installation, you should know some technical data:
- Connection diameter - 1 ”;
- Each section has a width of 80 mm;
- Maximum allowable working pressure is 40 bar.
Sira rs 500 heating radiator reviews often mention the importance of installing the right piping. Its main element is a temperature regulator.
The average cost of one section is 1155 rubles.
Sira gladiator
To complete the heating with more affordable batteries, the company offers a range of models of the Gladiator series. According to external data, they are almost completely identical to RS Bimetal. The difference lies in slightly worse technical specifications. In particular, the heat transfer coefficient is less than that of RS.
One section of the Sira Gladiator bimetal heating radiator currently costs from 720 rubles.
Independent connection of battery sections is not recommended. For this, special equipment is used to ensure good crimping of the assembly units.
Sira Aluminum Radiators
Welding technology is used to make Sira aluminum radiators. Water channels are formed after connecting 2 parts of the structure into a single unit. This technique leads to a lower value of the maximum allowable pressure - up to 16 bar.
Unlike unpretentious to the operating conditions of heating radiators Sira rs 500 series, aluminum models are recommended to be installed in stand-alone systems with pressure stabilization. For central heating, periodic pressure surges are characteristic, which often leads to water hammer. Not always aluminum construction can withstand such an operation.
It is important for the consumer to consider the following qualities of these radiators:
- Affordable cost. If we compare Sira bimetal and aluminum heating radiators by this indicator, the latter will be 15-20% more expensive;
- Increased heat dissipation;
- The need for periodic flushing to prevent rust.
A novelty in the company's assortment is Sira aluminum radiators from the Ali Princess and Ali Queen series. A feature of their design is the external fins for convection of air. They are directed towards the room, which provides an even distribution of heat throughout the room.
The maximum number of sections recommended for installation is 15. For optimal heat dissipation, the manufacturer advises mounting radiators that consist of a minimum of 4 sections. The average cost of each of them is 550 rubles.
For mounting radiators, it is recommended to use kits from Sira. They are designed for a specific type of battery.
All Sira heating radiators are RAL 9010 white powder coated. Therefore, if you need to repaint the surface - you can not remove the factory layer. For this, it is best to use special paints.
