Sectional bimetallic radiator Sira: reviews. Sira heat sink connection

Sira heating radiators from a well-known Italian manufacturer are suitable for installation in various types of premises - both public and residential. The manufacturer is engaged in the production of aluminum and bimetallic heating appliances.

In the manufacturing process, technologies are used that ensure efficient work on heating the premises with fairly low energy costs.

According to consumers' feedback, the design features of the devices contribute to resistance to pressure jumps, high heat transfer, which ensures the reliability of the radiator and the heating system as a whole.

Strength

In the production of bimetallic radiators Sira technology is used, implying the filling of steel channels to move the coolant with a high-quality aluminum alloy.

The designers have developed a special configuration of channels made of a special steel alloy. Thanks to this, a record-breaking mechanical strength of the heating devices, resistance to aggressive media and high heat transfer are ensured.

The Sira radiator is designed to withstand the sudden changes in temperature and pressure that occur so often in the heat network.

Reliability and tightness

The use of O-ring rubber heat-resistant gaskets during the assembly of sections into a single heating device allowed to achieve absolute reliability and tightness of the structure, unlike other systems with gaskets made of paronite. Due to the absence of "pockets" in the lower part of the sections (sludge collectors), the possibility of forming gases (including hydrogen) is minimized.

Heat dissipation

The technology of production of these devices has been improved by Italian specialists and allowed to develop bimetallic radiators Sira with excellent heat output. The maximum temperature regime of the heat carrier is 110 ° C.

Coating

The Sira radiator is coated with a Class A powder enamel using innovative tribo technology. This is an incredibly smooth coating, reminiscent of ceramics.

Guarantee

The manufacturer guarantees that the Sira heating radiators will operate uninterruptedly for 20 years, but only with the use of original components, as well as compliance with the installation requirements.

• Pressure of crimping - 60 atm.
• The maximum possible temperature of the coolant is 110 ° C.
• Working pressure - up to 40 atm.

Basic views

To date, the manufacturer can offer its customers the following types of heating appliances:

• Hybrid and bimetallic radiators.
• Aluminum - extrusive and cast.
• Towel dryers.
• Steel electric batteries.

In addition, it should be noted that any Sira radiator before going on sale is tested for joint work with all types of boilers - from solid fuel equipment to modern condensing devices. This takes into account the characteristic differences that are inherent in aluminum and bimetallic radiators.

Bimetal radiators Sira: reviews

Currently, the leader in sales are bimetallic instruments Sira. When developing their design, all the problems and shortcomings that may arise during the operation were taken into account.

At first glance, the sectional bimetallic radiator Sira is not much different from similar equipment of other brands. The main distinguishing feature of Sira heaters is the absence of welding seams. Each section is made by molding on its own production facilities. This significantly reduces the likelihood of leaks with increasing pressure. After all, very often the cause of the breach of the tightness of the radiators is the welding seams.

According to consumers' reviews, this equipment has the following features:

• A small amount of coolant, which is distributed through the channels of the device and thus provides rapid heating.
• Due to the special configuration of the outer edges of the device section, optimum convection of the air flow is ensured.
• The coolant channel is made of a special stainless steel alloy. It completely protects against corrosion.

All Sira heating equipment is painted white RAL 9010 by powder processing technology. Therefore, if there is a need to change the color, the factory layer should not be removed. For this purpose it is best to use special paints.

Sira RS Bimetal

Bimetal radiators Sira (reviews confirm this) are considered the most durable and reliable. These include the model Sira RS 500, where the last figure indicates the distance between the axes. The company positions such radiators as equipment of the advantage class. For the installation it is necessary to know the following technical data:

• The maximum allowable pressure is 40 bar.
• The width of the section is 80 mm.
• The diameter of the joint is 25 mm.

In the reviews of these radiators, the importance of proper tying is often mentioned. The thermostat is its main element.

On average, the radiator Sira RS Bimetal costs about 1200 rubles.

Sira Gladiator

To complete the heating system with more affordable heaters, the company offers its customers a line of models of the Gladiator series. Outwardly, they practically do not differ from the previous version. The difference is only in a few of the worst technical characteristics.

One section of the Sira Gladiator radiator can be purchased for 750 rubles.

Connection of radiators Sira

Any of the connection schemes listed below can be implemented in a heating system with forced movement of the coolant, in other words, with pumping equipment. Connection types:

• One-way connection. The supply pipeline is located on top, and the return pipeline is on the bottom. This method of connection ensures uniform heating of each section of the heater. This is an ideal option for owners of single-story mansions and villas.
• Lower connection. A good solution for heating systems in which the location of pipelines in the construction of the floor is provided. The supply and return piping is fed to the lower branch pipes, which are located on opposite sections. The disadvantage of this scheme is the uneven heating of the upper part of the radiator.
• Diagonal connection. This option involves the use of a cap and a Maevsky crane, as well as a large number of sections. The supply pipeline is on top, the return pipeline is on the bottom. With this method of connection, the coolant evenly fills the radiator, which contributes to maximum heat transfer. The efficiency of the system is increased - the heat losses are reduced to 2%.

Step-by-step instruction

• First of all, you need to make a markup for the subsequent installation of brackets.
• Then the brackets are fixed to the wall.
• The radiators are fitted with Mayevsky cranes.
• After that, heat regulators, plugs, valves and valves are mounted.
• Horizontal leveling of the heaters placed on the brackets is performed.
• With the help of transient strings, the radiators are connected to the piping system.
• At the end, the heating system is pressurized and the coolant is pre-started.

In practice, the efficiency of even a qualitative heating system decreases with time. In this regard, the owner often faces the problem of replacing certain of its components.

To change or install radiators, you do not need to have special skills, just follow the step-by-step instructions, have the appropriate tool and at least have a little understanding of the specifics of this field.
