Rating of the best bimetallic heating radiators for 2022

Bimetallic heating radiators - how does the novelty differ from traditional options? Massive cast-iron batteries looked aesthetically pleasing, while aluminum counterparts quickly lost their original gloss. In addition, the first type had a high heat transfer, unlike aluminum counterparts. Bimetal is a compromise between lightweight aluminum and massive cast iron batteries, which were in great demand 50 years ago. Modern designs are more technologically advanced, have their own characteristics and disadvantages. They differ from each other in size and cost.

Feature of the material used

First of all, you need to pay attention to the fact that the radiator is reliable. An excellent solution would be a product made of stainless steel. However, such material belongs to the category of expensive, heavy and extremely difficult to process. When a battery is made of this type of corrosive material, there will be no variety of shapes. It also implies excessive reliability, which is extremely unprofitable for the manufacturer.

The addition of aluminum will help make the machining process less costly and labor intensive. Such a material is easy to cast and is considered not only immune to corrosion, but also to electrochemical degradation. Such an alloy belongs to the category of light. In addition, it is not able to withstand regular dynamic impacts.

However, over time, a solution was found. It was decided to fix the steel collector inside the mold. The chosen form was simple, which allowed assembly even for a person who is not distinguished by professionalism.At the end of the aluminum alloy mold pressing, the embedded element remained inside the structure and became a second skin. Thus, heat transfer was carried out without obstacles. And the body of the bimetallic device itself was reliably protected from the effects of the coolant.

The modern buyer needs to pay attention to such factors that will help to find a high-quality bimetallic radiator. Products must meet the following parameters:

1. Gaskets and nipple connections must be reliable. Even after years of operation, they must maintain tightness at times of sudden temperature fluctuations.
2. Injection molding is considered the key to the formation of a quality product. It is extremely important not only the preparatory work, but also the observance of the established proportions.
3. To withstand abrasion, a steel liner of normal thickness is required.
4. High manufacturability, welding and molding, which are carried out exclusively on modern equipment. This reduces the risk of internal stress. For heating systems, this aspect is extremely important.
5. There are a number of welding rules that apply to each of the key structural elements.
6. Placing threaded bushings on the manifolds, and not just tubular inserts that were placed in the section channel. In fact, the principle of using a mortgage element has changed.

When such costs become justified

The use of modern technologies makes it possible to achieve the manufacture of both durable bimetallic and aluminum radiators. We are not talking about price. However, the question is still urgent today, because such expenses must be justified.First of all, we are talking about technical necessity. It makes sense to install bimetallic structures only when the embedded element, which is located inside the heating system, will perform at least several tasks from the general list of possible ones.

In particular, we are talking about such heating systems that do not use a water treatment unit. It is also possible to use an unusual type of coolant, which is characterized by the presence of a more aggressive environment. In this case, the purchase of bimetallic batteries will be more than justified, because there will be no need to purchase expensive equipment that is used to regulate the acidity of the environment. In addition, such auxiliary equipment allows both mechanical cleaning and cation filtration.

Mechanical impact is also considered an important factor. This can result in pressure surges during operational switching, pressure testing and system replenishment. Similar phenomena are observed in centralized heating systems, which belong to the category of communal facilities. What should you also pay attention to? It's about safety margin. For bimetallic radiators, it is high.

The only limitation is considered to be the requirement regarding the high inertia of the system used. This will be of particular importance if the coolant of the building structure is small, and the thermal insulation is of high quality. Thus, cast iron will help smooth out daily temperature fluctuations. However, its flexibility in zonal adjustment falls short of expectations.

It should also be remembered about the temporary losses during heating of batteries of this type. Steel has a higher heat capacity.However, one should not forget about the specific layer between the housing and the heat exchanger. If high-quality Italian and Russian-made products are used, then this indicator can be leveled in several ways. The response time required to recognize a change in heat head is reduced by 2-5% compared to the same aluminum units. Chinese-made equipment is not designed for such tricks.

Selection Guide

In order to decide on the place where to buy radiators, you need to scroll through the catalogs of several online stores. Thus, you can get an idea about each of the types of products presented on the modern market. It will also help to identify the average price for the sample you like. However, one should not give preference to little-known manufacturers and expensive new products. Perhaps the sample you need is produced by a domestic concern.

There are only four materials from which water convectors are made:

1. Bimetal (monolithic and units consisting of a certain number of sections).
2. Cast iron.
3. Aluminum.
4. Steel.

When choosing a unit, you should choose its power correctly. To do this, you will need to independently calculate the required amount of heat and the available supply standards. There are several ways to accomplish what you want to do. It is possible to use data regarding the volume of the room and the heat loss of the building.

Step-by-step instructions on how to choose a water convector

1. Popular models can be suitable for all characteristics, but their cost will be appropriate. It is necessary to stop at the "golden mean". You should not buy too cheap equipment, and even the most expensive may not be a necessity.
2. Just an attractive appearance may not be enough. The selected model should be suitable in terms of functionality, color, size (height) and connection method. The battery should look organic not only in the room itself, but also fit in the niche intended for it.
3. Before you buy, and then install a battery in a high-rise, you need to make sure that the heating section is suitable for the declared characteristics. In this case, the operating pressure of the unit must be less than 12 atmospheres. Such information is contained in the product description and its passport.

It should be noted that in most cases, the installation of radiators is carried out independently at home. In this case, you need to make sure that you can install it yourself. Also, the kit should contain the necessary jumpers and auxiliary components that the master will need.

4. But for private houses, this aspect is not considered so important. Such characteristics during the construction and subsequent installation of the heating system are not taken into account. The exception is coal or wood boilers, which are responsible for heating.In this case, it is necessary to buy a sample that can function in the presence of a high temperature coolant. The higher the value, the longer the batteries will last.
5. The popularity of the models is important, but not as much as the way the radiator itself is connected. It is much more convenient for subsequent repairs and connection of the lower eyeliner. In this way, existing pipes will be easier to hide. The lateral type of connection implies that the pipes will be walled up in the walls (it is not possible to fix the breakdown without subsequent repair) or remain in sight.
6. There are several options for mounting the device. Not only wall models are in demand, but also no less high-quality floor models. The equipment will play an important role and it is worth paying special attention to this. It is somewhat easier to have a jumper from the same manufacturer on hand, compared to one that was bought at random in a nearby store. The last option may not fit at all in size. The base kit should include fittings and brackets. Otherwise, you will have to buy everything yourself.

It is worth noting that Mayevsky's valves and faucet are often bought separately. You should not look for such attributes in the kit. After choosing a model, you can proceed to the selection of equipment of the appropriate power.

Conclusion

First of all, when buying new heating radiators, you should pay attention to the main material from which they are made. It is not recommended to use aluminum and steel, since the first option suffers from accelerated corrosion, while the second one suffers from the slightest pressure drops. Bimetallic structures are significantly more expensive than similar types of products. However, if first of all you pay attention to indicators such as durability, quality and reliability, then you won’t find better bimetallic radiators. It is advisable to pay once and not face breakdowns for 10-25 years than to buy a less reliable device and call the master before the next heating season.
