In harsh climates, people live in a heated room for almost six months. 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 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 recently become increasingly popular, however, it is important to decide which ones are the best.
Why you should choose a bimetallic radiator
The best models of bimetallic batteries have higher strength, they are able to endure pressure up to 35 atmospheres. If we consider the advantages, then it is worth highlighting a sufficiently long service life, a high level of strength, aesthetic appearance and modern design, as well as high heat transfer. Bimetal heating batteries are also distinguished by high resistance to corrosion. This is due to the fact that one of the materials is steel, which is in contact with the coolant. 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 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 are able to block the lower collector by shearing. This is possible with varying degrees of expansion of materials due to temperature exposure.
Varieties of bimetallic batteries in size
Bimetal heating batteries can have different heights. Low products, which have an interaxial distance of eyeliner in the range from 200 to 250 millimeters, do not have vertical intra-section channels. But the batteries, which are called vertical or tall, can have a size of 2.6 meters. The most popular are those designs with a center distance of 500 millimeters. The reason for this prevalence is simple, it lies in the absence of the need to adapt the liner after replacing the cast-iron radiators. Among other things, if we exclude vertical radiators, which are not compatible with any design, then sections of this size have maximum heat transfer.
Differences in connection method
Bimetal heating batteries may differ from each other in the connection method. Most often, plugs and locknuts are used that allow you to connect a heater to the wiring. But, if you choose a battery with a lower connection, the inset will be almost invisible, since the two threads are oriented vertically and are located below, under the battery itself.
Description of bimetallic radiators with different heat output
Recently, modern consumers have increasingly begun to choose bimetal radiators. Heating batteries of this type may differ from each other in terms of heat output. You can find this information in the accompanying documentation, but 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 equal to 150 watts. If you see radiators with a center distance of 250 millimeters, the allocation to one section is 120 watts.
Reviews about the quality of bimetallic radiators from different manufacturers
If you want to choose the best bimetal heating radiators, then you should pay attention to the manufacturer Royal Thermo. As users mention, he makes products that differ in non-standard design, as well as high technical characteristics. These batteries are based on high alloy steel, which ensures a long service life. Some of the best are batteries that Thermo Biliner makes. They are distinguished by a collector made of stainless steel, which allowed the manufacturer to get almost perpetual 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 customers, 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 pay your attention to the Russian manufacturer. The Bilyuks company makes high-quality devices for which the factory guarantee is given for 10 years. The section's standard heat dissipation is 182 watts. Such equipment will cost less in comparison with foreign ones, which is why the modern consumer quite often prefers these products.
The Ukrainian company Elegance also provides a ten-year guarantee for its products, the working pressure remains the same as in the case described above, which is very pleasantly combined with an affordable cost. As buyers emphasize, it varies within 320 rubles. in one section.
Description of alternative Russian offers
If you also decide to choose a bimetal heating radiator, which batteries are best , you should decide before you visit the store. There you may encounter a difficult choice. For example, Konner offers products based in China. The characteristics are very good, the pressure still remains at the level of 30 atmospheres, while testing the product can withstand 45 atmospheres. In this case, the temperature can reach 130 degrees. All this is complemented by the affordable cost, which is equal to 380 rubles. in one section.
For comparison, you can consider the products of the brand "Rifar", which are completely Russian products. For them, the declared operating temperature is 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 are very common lately. Leroy Merlin offers them in a wide range. For example, a 4-cell battery brand Rifar Forza 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, the 4-cell “Extreme” battery, which weighs 7.64 kilograms, will cost 2700 rubles.
Installation Features Reviews
The master must install a valve on each battery, which can be automatic or manual. It is intended for the exit of accumulated air from the radiator. Correct its position using multi-thread. In order to avoid 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 air 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 carried out using dowels or mortar, then you can proceed to the installation of the device. Using a thermostatic valve or faucet, the battery must be connected to suitable communications. A relief valve is installed at the top of the product.
Conclusion
Bimetal heating batteries , the prices of which should interest you, are presented today in a wide assortment. To understand which radiator to choose, you should familiarize yourself with the quality characteristics of the products, the materials at the base and the reputation of the manufacturer in more detail.
