In a harsh climate, people live in a heated room for almost half a year. For many, the heating system in an apartment or house is a heavy radiator based on cast iron. Such batteries do not emit enough heat and can spoil the design of any interior. All consumers who decide to change the heating radiator are more careful when choosing. This is facilitated by the fact that in modern stores the range of such systems is quite diverse. It is worth noting that bimetallic heating batteries have become more and more popular lately, but it is important to decide which ones are the best.
Why choose a bimetal radiator
The best models of bimetallic batteries have higher strength, they are able to withstand pressure up to 35 atmospheres. If we consider the advantages, then it is worth highlighting a fairly long service life, a high level of strength, aesthetic appearance and moderndesign, as well as high heat dissipation. Bimetallic heating batteries are also highly resistant to corrosion. This is due to the fact that steel, which is in contact with the coolant, acts as one of the materials. The second material is aluminum.
Differences in bimetallic radiators by manufacturing method
Bimetallic batteries also differ in production technology. The first method involves applying aluminum protection to the steel frame, while the second manufacturing option involves strengthening the channels with special tubes that are made of steel. The first technique eliminates the contact of aluminum with the coolant, which makes the oxidation process impossible. For the second method, an important parameter is the reliable fastening of steel tabs, which can block the lower manifold by shear. This is possible with different degrees of expansion of materials due to the effect of temperature.
Varieties of bimetallic batteries by size
Bimetallic heating batteries can have different heights. Low products, which have an interaxal distance of eyeliners ranging from 200 to 250 millimeters, do not have vertical intra-sectional channels. But the batteries, which are called vertical or high, can have dimensions of 2.6 meters. The most popular are those designs whose center distance is 500millimeters. The reason for this prevalence is simple, it lies in the absence of the need to adapt the eyeliner after replacing cast-iron radiators. Among other things, if you exclude vertical radiators, which are not consistent with every design, then sections of this size have the maximum heat transfer.
Differences in connection method
Bimetallic heating batteries may also differ from each other in the way they are connected. The most commonly used plugs and lock nuts, which allow you to connect a heater to the supply. But, if you choose a battery with a bottom connection, the insert will be almost invisible, since the two threads are oriented vertically and located at the bottom, under the battery itself.
Description of bimetallic radiators with different heat outputs
Recently, modern consumers are increasingly choosing bimetallic radiators. Heating batteries of this type can also differ among themselves in terms of thermal power. This information can be found in the accompanying documentation, however, there are average values.
If the center distance is 500 millimeters, then the power is 200 watts per section. When the first value is reduced to 350 millimeters, the power becomes 150 watts. If you have radiators in front of you with a center distance of 250 millimeters, then the allocation per section is 120 watts.
Reviews on the quality of bimetallic radiators from different manufacturers
If you want to choose the best bimetallic radiators, then you should pay attention to the manufacturer Royal Thermo. As users mention, he manufactures products that are distinguished by non-standard design, as well as high technical characteristics. These batteries are based on high-alloy steel, which ensures a long service life. One of the best batteries is made by Thermo Biliner. They are distinguished by a stainless steel collector, which allowed the manufacturer to obtain almost eternal batteries.
All of the above manufacturers are located in Italy, but if you are attracted to German factories, then you can find Oasis radiators on sale. However, do not rush to purchase them, because, according to buyers, they have a low cost, and also do not have an online presence, which looks very strange for Germany. However, as practice shows, these products are capable of undergoing pressure up to 30 atmospheres during operation.
If you are interested in the question of which bimetallic heating battery is better, then you should turn your attention to the Russian manufacturer. The Bilux company manufactures high-quality devices, for which a factory warranty is given for 10 years. The standard heat dissipation of a section is 182 watts. Such equipment will cost less compared to foreign ones, and therefore modernthe consumer often prefers this product.
The Ukrainian company Elegance also provides a ten-year warranty for its products, the working pressure remains the same as in the above case, which is very nicely combined with an affordable price. As buyers emphasize, it varies within 320 rubles. for one section.
Description of alternative Russian proposals
If you also decide to choose a bimetallic heating radiator, which batteries are best, you should decide even before visiting the store. There you may be faced with a difficult choice. For example, Konner offers products that are manufactured in China. The characteristics are very good, the pressure still remains at the level of 30 atmospheres, when tested, the products withstand 45 atmospheres. In this case, the temperature can reach 130 degrees. All this is complemented by a democratic cost, which is equal to 380 rubles. for one section.
For comparison, you can consider the goods of the Rifar brand, which are completely Russian products. For them, the operating temperature is declared within 135 degrees, and the test pressure is 100 atmospheres. More modest characteristics are characteristic of Breeze radiators, which are manufactured in the Moscow region. Their working pressure is 25 atmospheres.
Cost
Based on the above factors, it can be noted that bimetallic heating batteries have been very common lately. Leroy Merlin offers them in a wide rangeassortment. For example, a 4-section Rifar Forza brand battery can be purchased for 2500 rubles, its weight is 5.44 kilograms. As for the 6-cell battery from the manufacturer Celcia, it can be purchased for 2700 rubles. It is worth considering that such a product will weigh 9.19 kilograms. For comparison, a 4-section Extreme battery, which weighs 7.64 kilograms, will cost 2,700 rubles.
Feedback on installation features
The master must install a valve on each battery, which can be automatic or manual. It is designed to release accumulated air from the radiator. You can correct its position using a multi-start thread. In order to prevent contamination of the valve area, special filters must be installed on the supply racks of the system.
A properly installed serviceable valve must be closed after bleeding, and the battery cavity must be filled with coolant. Before installing the radiator, markup should be carried out, the brackets should be strengthened, which is done with dowels or mortar, then you can proceed to install the device. Using a thermostatic valve or tap, the battery should be connected to suitable communications. A relief valve is installed at the top of the product.
Conclusion
Bimetallic heating batteries, the prices of which should interest you, are presented today in a wide range. To understand which radiator to choose, you should become more familiar with the quality characteristics of the products, the base materials and the reputation.manufacturer.
