Bimetallic radiators: What is better to choose?

An important part of creating the heating system is radiator selection. Their efficiency and effectiveness depend on the speed and quality of the heating area. In contrast to the Soviet era, when there was no analogue iron batteriesIn modern times, it offers a huge range of different radiators. Bimetallic radiators are considered one of the functional variants. What is better to choose depends on the specific firms and the characteristics of the material.

design Features

Bimetallic model are consistent with all rules and restrictions that accompany the installation of the apartment. By type of bimetallic products like aluminum, but their internal content differs.

What is better to choose Bimetallic radiators prompt study of the production device. The bimetallic element is different parts of stainless steel, which protect the aluminum from hazardous components in water. With these details, the equipment is not in contact with the body coolant. The steel is characterized by resistance to the effects of acidic or alkaline medium, which is central in Schemes heating.

In addition, such products have all the qualities of instruments made of aluminum. This presentable appearance, small size and the increased rate of heat transfer. radiators They represent heating devices which consist of the same sections. Each element - a frame made of pipes welded together by means of welding. The surface of the roads have a 3-4 mm thick, making the products more resistant to the jumps pressure and waterhammer. Frame processed-coated aluminum alloy, which has a higher emissivity.

Helpful information! All bimetallic embodiments have the same height, and the gaps between the vertical elements vary depending on the design of nuances and have the value 200, 350 or 500 mm.

Monolithic and sectional model of bimetallic radiators

Traditional assembly bimetallic articles is an option of a number of sections. Sectional products can be damaged by the heat carrier, which influences the place of the device connection. Moreover area exposed joints water leakage because of high pressure in the structure. Therefore, upgraded technology has been developed, which is performed by the cast manifold, and is mounted on top of the aluminum casing. These products are called monolithic.

Many people wonder what the best bimetallic radiators - section type or monolithic.

Monolithic have the following advantages:

• Longer service life of 40 years.
• The pressure in the apparatus can be up to 100 bar.
• Power rating of 100-200 watts.

Models with molded core can not change, add or remove. But they are produced in different sizes and height and width. Thus the cost of the monolithic production will be higher. Such models should opt for the apartment, which is located in a block structure where the circuit presence felt pressure coolant.

Bimetallic radiators and polubimetallicheskie

Depending on the design features of such devices are divided into two types: polubimetallicheskie and bimetallic.

The bimetallic aggregates shell of steel - is a frame made of tubular horizontal and vertical type, which are fixed by welding. Welded system is filled with aluminum. The liquid is contacted with the steel part. In polubimetallicheskih radiators vertical steel reinforced parts.

How to choose Bimetallic radiators: which is better?

Determine what Bimetallic radiators for better apartments, it is recommended to consider the products of individual producers. One of the most popular companies producing products of this type, is a Global Style. The company's products fully adapted to Russian conditions. Company Radiators can be installed with Metal, steel, copper or plastic pipes.

In addition to "Global" in our market, there is another Italian manufacturer of Sira, which offers three products, mainly polubimetallicheskie. In this case, devices are known excellent emissivity. In order to maintain the desired temperature need less number of sections than other companies of similar products.

Of domestic manufacturers is to provide the company "Rifar". Polubimetallicheskaya products of this company is characterized by reliability and a long service life. Use model demand special anti-corrosion coating Rifar-zin, which makes such resistant aluminum.

In the table it can be seen significant characteristics of radiators of several known firms in example models with center distance of 500 mm.

Italian production is focused on the durability and reliability of products even at the expense of thermal power indicator.

Helpful information! Rifar company offers a model that operates at a pressure of 100 bar. This is possible thanks to the monolithic installation, where there are no threaded parts.

Pros and cons of heating devices

The structure of bimetallic products helps to improve quality indicators of this type of equipment. Steel rod in the device is characterized by a long service life and extraordinary resistance to corrosion. The shell is created from aluminum, which provides a rapid transfer of thermal energy.

These products have the following parameters:

• Long service life. Steel elements within the housing are resistant to corrosion and damage, so the life of the device can reach 20 years of age;
• strength. The housing can withstand considerable pressure and is not afraid of water hammer;
• a variety of types of products, stylish look and a combination of any interior style;
• an excellent indicator of heat, little inertia and resistance to corrosion;
• compactness, ease of installation and low weight;
• economy. Water feeders create an optimum combination of thermal inertia and energy costs.

The disadvantages of such designs can be attributed significant value and a small measure of bandwidth.

What better heating radiator: aluminum or bi-metal version

Determine what the best heating radiators, aluminum or bimetal, should carefully examine the features and characteristics of these options.

Aluminum patterns are made from the molten aluminum, which is poured into molds. In this case, the radiator becomes completely sealed, which prevents leaks. Aluminum has a greater thermal conductivityThan bimetal or cast iron. In addition, the material differs excellent resistance to corrosion.

By cons models include the fragility of the material, the product can be easily damaged. Also, such devices are designed for low pressure in the pipes. The main advantage of the bimetallic radiator as compared with the aluminum analogue is a high resistance to high pressure. Similar designs can be installed both in apartments and private houses.

Helpful information! Aluminum device is a pressure indicator 16 bar, but in apartment buildings, even in a season setting pressure parameter does not exceed 15 bar. But in private households should be careful, because the pressure is often injected with additional devices.

Rules for the calculation of sections of bimetallic radiators

Before we come to the connection of bimetallic radiators, should be calculated. One section of this device is designed to warm the two square meters of space. To choose the right number of sections we calculate:

• produced area count premises;
• the obtained result is multiplied by 100 watts. If the ceiling area larger than the standard value, the correction factor is applied which is equal to 1.1;
• number, which has turned out, divided by the value of one heat transfer section.

Owners of private housing should carefully perform the calculation. Thus it is necessary to take into account the thermal conductivity of elements such as windows, roofs, walls and floors.

Rating bimetallic radiators

To choose the best option you should use rating bimetallic radiators.

Popular Products evaluated using the following criteria:

• heat transfer rate;
• complaints about operation of the device;
• effect on the surface of the coolant;
• resistance to temperature spikes;
• workmanship, coatings and parts;
• design solutions.

Rating based on the analysis of products with interaxle spacing of 500 mm.
