Heating issues are relevant in our country due to the fact that it is cold in most of its territory. It is for this reason that heating a living space periodically occupies the thoughts of Russians. This means that we should consider this topic and tell you more about bimetallic heating radiators. Their technical characteristics are excellent, so they are in demand among buyers. Consider them and compare with competitors.
General information
Bimetal heating radiators are very distinguished by their characteristics and therefore are currently one of the leaders in their product group. In terms of mass production, they lose only to the old classic cast-iron radiators. It can be assumed that this happens because the cast-iron version was extremely common at one time. Until now suchbatteries are reluctant to change, although the deadline has already come. This is due to the peculiarities of people's thinking and their difficult financial situation, but we will not go away from the topic and talk about it.
Radiator device
Bimetallic batteries consist of two metals. The inner part is made of stainless steel and the outer part (heat exchanger) is made of aluminium. Vertical channels made of steel are pipes. They are connected by welding in their lower and upper parts with horizontal pipes of larger diameter, which, after the assembly of the battery, form collectors. A coolant circulates in this tubular steel structure.
Battery sections can be equipped with a thread (coupling) for interconnection, or can be factory welded (rare). Hence the division into two types:
- sectional collapsible radiator;
- one-piece one-piece version.
It must be said that non-separability is rather relative, because you can always add several separate sections to a non-separable battery or simply connect several blocks together that are considered non-separable.
Features
Excellent characteristics of bimetallic heating radiators force people to choose them. They are bought for both private houses and city apartments. The peculiarity of the bimetallic battery is that it, when compared with aluminum andsteel counterparts, has a noticeable pronounced resistance to high pressure and high temperatures.
But it is worth saying that the above applies only to quality products. This means that it is worth giving preference to manufacturing companies that have been on the market for a long time and have been able to prove themselves perfectly during this time. It is necessary to responsibly approach the choice of bimetallic heating radiators. The technical specification is an important aspect, but other points also matter (manufacturer, etc.).
Steel channels are characterized by incredibly high resistance to various aggressive components of the system coolant. This is especially noticeable in comparison with all-aluminum counterparts. Bimetal has an acid-base index (pH) of 5-11 units, and this is many times higher than that of aluminum batteries. This also makes bimetal heating radiators more popular with buyers. The characteristics of such products can be considered close to ideal. This should always be considered when choosing batteries for the home.
Bimetallic heating radiators: characteristics
It must be said that bimetal has the best performance when compared with aluminum radiators and steel batteries. This is because aluminum is better in terms of heat transfer, and steel is better in terms of heating. Thus, the bimetallic option is the pluses of both metals and the exclusion of the minuses of each of them individually. Now we can talk about specificmanufacturers to learn a little about the situation on the market and the main players on it.
Characteristics of Rifar bimetallic heating radiators
Rifar is our Russian manufacturer from the Orenburg region (Gai city). The production is modern, the line is fully automated. The batteries are an internal monolithic stainless steel collector, which is placed in an aluminum case.
High quality products are confirmed by compliance with European quality, as well as Russian main regulatory documents (GOST 31311-2005, TU 4935-004-41807387-10).
Very often you can find bimetallic heating radiators "Rifar Monolith 500" in multi-storey residential buildings and office premises. The characteristics of these batteries are such that they are optimally suited for these purposes (high strength and full compliance with all parameters for use in domestic heating systems).
It must be said that the Rifar Monolit has two dimensions. The difference lies in the distance between the axles. The 500 mm option was just mentioned above, now it's time to talk about 350 mm. Very often you can find bimetallic heating radiators "Rifar Monolith 350" in country and private houses. The characteristics and dimensions of the radiator are such that it can be used where a 500 mm high battery does not fit. This is an important feature that needs to be mentioned when talking about heating radiators.

STI
Sanitaria Technica Italiana has been on the market for about 30 years. The brand's products meet absolutely all international quality standards and customer requirements. At the same time, it should be noted that the price of brand products is very affordable.
Italian STI radiators appeared in Russia only in 2013. But, despite this, they quickly conquered a significant part of the market in this niche. The company has not only its own modern production equipment, but also its own technology department, in which all products undergo a three-stage strict quality control.
Let's take a closer look at the STI bimetallic heating radiator. Reviews, characteristics - this is the most important point in this case, it was then that welet's touch on. Consider the parameters on the STI Grand model:
- The working pressure of the coolant is 2.4 MPa.
- Maximum coolant temperature - 110 0С.
- Heat dissipation of one section - 195 W.
- Capacity of 1 section - 0.2 liters.
- The weight of one section is 1.8 kg.
Let's pay attention to the main parameter of bimetallic heating radiators - the heat transfer characteristic. It is worth pointing out that the Italian version has a heat transfer of one section of 195 W, while our domestic version considered above has a similar parameter of 196 W. Does this mean that these are the same indicators? To find the answer to this question, you need to turn to the reviews.
Reviews say that STI radiators heat the premises better. The difference is not so noticeable in small areas, but if we are talking about large houses, then this little thing already becomes something significant.
WARMA
WARMA is a large Russian-Chinese company. The production is located in China, but only high-quality European equipment is used in automated lines, and quality control is carried out by Russian specialists.
Products comply with GOST 31311-2005 and other standards in the field of central heating system. WARMA bimetallic batteries are suitable for installation both in private houses and in apartments with centralized heating plants.
Consider the WB350 model to compare with the above bimetallic heating radiator350 mm. Specifications WB350:
- Working pressure - 25 atm.
- The heat output of one section is 130 W.
- Maximum coolant temperature - 110 0С.
- H2 is 6-10.5 pH.
- Section volume - 0.17 liters.
- Weight section - 1.45 kg.
- Inlet diameter - 1 inch.
- Radiator color - white.
- Guarantee - 10 years.
If you analyze the WB350 and Rifar Monolit 350, you can see the similar parameters of these bimetallic heating radiators. Dimensions, specifications are almost the same, but there are some nuances that you should pay attention to.
Rifar's operating pressure is noticeably higher, which means that the quality control pressure was also higher. The weight of the Rifar section is also greater than that of the Russian-Chinese competitor. From all this, we can conclude that WARMA products are at least somewhat inferior in terms of quality to similar products from the Russian manufacturer Rifar.
