Bimetal radiators are a new trend in residential heating. Such heaters are increasingly found in apartments and private homes. And in this article we will help you figure out which bimetallic heating radiators are better and how they are superior to aluminum and semi-bimetallic appliances. You can also find important tips on choosing a heating radiator and interesting videos on this topic.

Bimetal radiators are rapidly gaining momentum Source kvartirnyj-remont.com

Bimetal or semi-bimetal radiators

Bimetal heaters are steel pipes connected by cold welding, which are covered with a layer of aluminum. Due to this, hot water does not interact with the outer shell of the radiator, which helps to avoid corrosion. Moreover, aluminum is applied in the form of figured plates, and this significantly increases the heat transfer area.

There are also copper cores of bimetallic radiators. They are suitable if the coolant is water with antifreeze. Such a composition can quickly destroy steel, but copper is resistant to it.

For semi-bimetallic radiators, the core is made of two metals. All vertical channels are steel, and horizontal channels are aluminum. The disadvantage of such devices is that they are not suitable for water with a high content of alkalis. They necessarily require a coolant purified from impurities.

Now about which heating radiators are better. For heating systems of the central type, it is bimetallic devices that are more suitable, because they are resistant to pressure drops and poor-quality contaminated coolant.

Semi-metal radiators are more efficient, but ideal conditions are needed for their normal operation. They are more suitable for private houses, and are much more expensive than bimetallic devices.

Bimetal or aluminum radiators

A little about which radiators are better, aluminum or bimetallic. In relation to the coolant, the advantage is clearly on the side of the latter. Aluminum does not withstand prolonged contact with water with a large amount of impurities.

Also, bimetallic radiators are more resistant to high pressure than aluminum ones. After all, the core is made of alloy steel, which has increased fracture and tensile strength.

However, in some moments, bimetallic heaters lose to aluminum ones. They are more bulky and heavy, cost much more, and the steel core reduces energy efficiency and reduces heat exchange with the room.

Externally, aluminum and bimetallic radiators are very similar. Source zamenabatareymoskva.ru

Definitely bimetallic heaters require increased heating costs. But they are more durable and more adapted to urban heating networks. At the same time, aluminum radiators are ideal for private homes, where owners can control the pressure and change the water in the system.

Types of bimetallic radiators

There are two main types - sectional and monolithic. Below we will tell you more about them and help you figure out which one is best for you.

Sectional radiators

They are assembled from several sections. Often performed in the form of a "layer cake" of heating plates. This discovery allows to significantly increase the area of ​​heat exchange with the environment. But there is a big drawback: any coolant destroys the joints of the components. The result is a relatively short service life.

Sectional heaters consist of several parts Source forum.usolie.info

Monolithic radiators

They also have a large heat exchange area, so they are in no way inferior to sectional heaters. Gives out one section of about 100-200 watts. Monolithic radiators are manufactured using a fundamentally new technology: the body is cast as a whole, and then processed by pressure. A layer of aluminum is applied over the steel frame under pressure.

Monolithic heaters are one piece Source www.teplodvor.by

The advantage of monolithic radiators is obvious. The service life is twice as high and is not 25 years, like sectional ones, but 50. But at the same time, they are more expensive by about a fifth. Their disadvantage is that they do not make it possible to add additional sections and thereby adjust the power.

If you think about the question of which heating battery is better for apartments in high-rise buildings, then the answer is unequivocal - monolithic. The point is a large pressure drop due to altitude.

Rating of bimetallic heaters

Below we will help you figure out which batteries are better to choose for your house or apartment. Consider the operating conditions, workmanship and some of the nuances.

Global Style Plus 500

Suitable for central heating systems. Well adapted to high pressure and strong acidity of the coolant. The sections are connected by branch pipes with a silicone gasket that protects against leaks. The steel contour is crimped under high pressure, which allows it to withstand strong water pressure. Another advantage of this model is the high quality of coloring.

But the downside is the rather high cost. On average, in the market it is 9,500 rubles. However, it is believed that the model is worth the money.

On our site you can find contacts of construction companies that offer services of any complexity. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".

A Russian-made monolithic heater that is rapidly gaining popularity. It is made in the form of a single steel block, which eliminates the possibility of leaks. The radiator does not require a constant coolant temperature. Withstands pressure on the internal circuit up to 100 atmospheres. Rifar Monolit 500 provides high heat dissipation with minimal energy loss.

But there is one caveat: the dimensions of the Rifar Monolit 500 heating radiator are fixed, like any monolithic device. Therefore, if it turns out that it is not enough or, on the contrary, too much, simply adding or subtracting sections will not work.

Sira RS Bimetal

One of the quietest heating radiators. Can be installed even in bedrooms. One block can include up to 12 sections, the number of which can be adjusted depending on the area of ​​the room. The inner shell is made of special steel, which is not subject to corrosion and can be used in combination with a low-quality coolant. Sira RS Bimetal provides a high level of heat transfer and is designed for a maximum pressure of 40 atmospheres, and the radiator is adapted to the water hammer inherent in a central heating system.

The Sira RS Bimetal heating radiator can often be found in apartments Source on-lineclimat.ru

But this model has one drawback: the quality of painting leaves much to be desired. Despite this and the rather high cost, many experts will answer the question of which bimetallic radiators are better - Sira RS Bimetal.

The fourth place in our ranking of bimetallic radiators is occupied by the Royal Thermo Revolution Bimetall 500. A very popular model from a domestic manufacturer. The device is adapted to rather harsh operating conditions and provides good performance. The design is wall-mounted, sectional, with an adjustable number of segments, the maximum number of which is 14 pieces. The Royal Thermo Revolution Bimetall 500 has a lateral connection. The heater is designed for operating pressure up to 30 atmospheres.

The main factor that makes the model one of the most common in Russia is the price. You can buy a heater for an average of 4,100 rubles. However, it is worth remembering that with sharp increases in the temperature of the coolant, the efficiency of the device is significantly reduced.

How to choose a bimetallic heater

When buying a device, it is important to consider a number of nuances. Going to the store, you need to know exactly how much power the radiator should give out, what dimensions it should have, and to what conditions it should be adapted. Therefore, we will help you figure out which bimetallic radiator is best for your home.

Calculation of the number of sections

Such a calculation is made based on the area of ​​\u200b\u200bthe room and the energy efficiency of the section of a particular device. It is believed that for every 10 m 2 of the room, ideally, there should be 1 kW of power. To calculate, you need to divide the area of ​​\u200b\u200bthe entire room by 10, and then divide the result by the power of one section. Then the whole value must be increased by 10% and rounded up to a whole number. This is how heat losses associated with external factors are taken into account. The result is the optimal number of radiator segments for a particular room.

Sectional bimetallic radiator can be adapted to a specific room Source c-o-k.ru

If, due to some features of the area or the house, the sectional heater does not provide the required temperature level, additional segments can be added to it. With a monolithic radiator, this will not work.

What to Consider

There are several points that you should pay attention to in order to understand which heating radiator is better in a particular case:

It's better when heater size maximum, because in this case the energy efficiency of the device is the highest. But it is important that the distance to the floor is at least 12 cm, and to the windowsill - at least 10 cm.

Ideally positioned bimetal heating radiator Source tengrinews.kz

Capacity is one of the most important parameters. The larger it is, the better the radiator heats. Therefore, for devices with a small volume of sections, the highest quality coolant without impurities is required.

More suitable for apartments monolithic radiators, because they are able to withstand sudden pressure surges, while at the same time, cheaper sectional models can be used for autonomous heating systems.

An interesting video clip on how to choose a bimetallic radiator for an apartment:

Briefly about the main

Bimetallic radiators are superior to semi-bimetallic models in terms of durability and unpretentiousness, and they are also more affordable.

Bimetal radiators are more durable than aluminum ones, but they are more expensive and take up more space.

According to the structure, there are two types of bimetal radiators: sectional and monolithic.

The most popular models of bimetallic radiators are Global Style Plus 500, Rifar Monolit 500, Sira RS Bimetal and Royal Thermo Revolution Bimetall 500.

In order to choose the right bimetallic radiator, it is worth considering its capacity, dimensions, and it is also necessary to calculate the number of sections for a particular room.

A little more attention!

Do you think bimetallic radiators are the best option for value for money or can they be classified as expensive and appliances? Write in the comments which heaters you prefer.

Let's start with what bimetallic radiators are, I will try to be as short as possible about this, “Bi” (from Latin - twice), the beginning of many Latin and Greek terms; means doubling. And as you may have guessed, radiators consisting of two metals, an alloy of aluminum and steel, are called bimetallic. These are the most reliable and, as a result, popular radiators installed in apartments for the last 10 years.

We will not single out any of the presented bimetallic radiators saying that they are better than all the others, since the reliability coefficient for any of the radiators presented by us is not lower than 99.99%, which is less than 1 piece. leaks per 1000 installed radiators, the price is not a decisive characteristic for everyone, and the choice depends more on the country and the design ambitions of the manufacturer.

We will start talking about the individual advantages of bimetallic radiators and start with the most popular and best-selling bimetallic heating radiators on the market today (the rating is based on statistics from 26,725 bimetallic radiators) and at the end of our article, we think you can easily choose for yourself the model that suits you to you.

And so meet the best-selling.

1 . Bimetal radiatorsRifar Monolit(manufactured in Russia) release since 2002. Estimated cost is 4337 ₽ for 1 kW of heated power (10 meters of area).

At the time of writing, 31% sold radiators.

To understand the features and advantages of this heater, it would be worth starting with the design of the radiator and the way it is assembled. A bimetallic radiator is the only radiator not only with fully steel interiors, but also with a fully welded structure (there are no gaskets that could potentially leak, although leakage of gaskets in a high-quality bimetallic radiator is extremely rare) hence its name "Monolit" and its very high working pressure among competing and non-competing heating devices of all types. And that's not all, Rifar produces Bimetallic radiators with a bottom connection and a built-in thermostatic valve, by the way, to our professional surprise, no manufacturer of bimetallic radiators does this, Rifar Monolit Ventil radiators deserve a separate place in the rating of bimetallic radiators, but for now we have decided do not complicate the rating with an identical model.

Note that the level of reliability of this radiator is so much overestimated from the real needs of thermal systems that, according to some opinions, its reliability is more of a marketing meaning than a practical one.

Very decent and modern design.

This radiator is bought by people with medium and high incomes, who do not seek compromises when it comes to reliability. We repeat that this line of radiators is an absolute hit on the Russian market. The only question that may arise for the Rifar Monolith radiator is do you need a radiator that will last longer than your home? ;-)

2 . Bimetal radiatorsRifar Base(manufactured in Russia) release in 2002 cost 3284 ₽ per 1 kW.

26%

The second best-selling bimetallic radiator today is Bimetal radiators, which are of excellent quality, like all Rifar products.

Its insides are not fully reinforced with steel, as in some other bimetallic radiators, the horizontal collector remains aluminum, but this is enough to withstand a working pressure of 20 atmospheres and last at least 25 years in any Moscow apartment. This model, like the Monolit, has a modification with a bottom connection and a built-in thermal control valve.

The bimetallic radiator Rifar Base has an already established classic design for sectional radiators and is perfect for modern apartment renovations that meet all modern requirements. This is an ideal choice for those buyers who do not want to overpay for an imported brand and not always justified excessive reliability.

3 . Bimetal radiatorSira RS Bimetal(made in Italy) release since 2004, cost 3869 ₽ per 1 kW.

14% sold radiators during the analysis period.

The 4th place in sales and again with a small margin is occupied by the Bimetal radiator, its competitive advantage is its individual design and, as always, impeccable Italian quality. For this, he can be forgiven for his not completely steel insides, since the horizontal manifold remains aluminum, but this will not prevent him from working in high-pressure systems up to 40 atmospheres for at least 30 years.

Its price is slightly more expensive than the leaders of our rating, but strangely enough, this fact did not greatly affect the ratio in the sales race. The bimetal radiator Sira RS Bimetal is the absolutely right choice if not only reliability and modern design are at stake, but also Italian individuality.

4 . Bimetal radiatorsGlobal Style Plus(made in Italy) release since 2007, 4811 ₽ per 1 kW.

13% sold radiators during the analysis period.

The third place in sales, although with a very small margin, is occupied by a bimetallic radiator from a well-known Italian brand with a very good reputation on the Russian market,. We’ll immediately tell you about the pluses of the Plus radiator, these are all-steel insides and a working pressure of 35 atmospheres, as well as an individual white color with a barely noticeable shade of ivory, which is positioned as a more advantageous color for a home interior radiator, unlike bright white competitors.

The design, which has become classic for a bimetallic radiator, will fit perfectly into almost any interior, and the device itself will last at least 35 years, and for some it will become not only a reliable radiator, but also an Italian piece of decor.

5 . Bimetal radiatorsRoyal Thermo Piano Forte(made in Italy) release since 2015, 4718 ₽ per 1 kW.

9% sold radiators during the analysis period.

Particular attention in our rating is occupied by a bimetallic radiator, a radiator with not completely steel insides, a horizontal collector is made of aluminum, the operating pressure reaches 30 atmospheres, and the service life is at least 30 years.

Once you look at this radiator live, you will not be interested in comparing its characteristics with other bimetallic radiators, since this is the most advanced, modern and bold design, reminiscent of piano keys. The radiator is available in three colors. If you are used to being modern and trendy, and a small overpayment rarely scares you, be sure your choice is Royal Thermo PianoForte.

6 . Bimetal radiatorsGlobal Style Extra(made in Italy) release since 2008, 4854 ₽ per 1 kW.

6% sold radiators during the analysis period.

In fifth place is bimetallic radiators, another model of the Global company, which has all the advantages of the Style line of the same name, including fully steel interiors, a working pressure of 35 atmospheres, and an individual white color with a touch of ivory. The main difference between this radiator and the Global Style Plus is only a slightly modified design and a smaller depth, which makes the radiator less bulky. Otherwise, it is still the same classic design, Italian quality and the right choice for a person who wants to take something more individual.

7 . Bimetal radiatorsglobal style(made in Italy) release since 1994, 4940 ₽ per 1 kW.

1% sold radiators during the analysis period.

And again Global, the bimetallic radiator has been produced since 1994 and is a classic model of the Italian brand Global. The working pressure of this device is 35 atmospheres, and the color scheme has the same individual white color with a hint of ivory.

Classic, individual, brutal and very recognizable design. Global radiators are always the right choice, and Global Style has been the right choice for 24 years in a row.

They are the most modern radiators among those currently existing. They are mounted without problems, allow you to get a lot of heat, and look attractive, in addition, they are not able to spoil the interior design. However, different radiators are sold in stores today, which differ in technical and design characteristics. Which of them is better to choose, you can find out if you read the rating by manufacturers and features.

The difference between semi-bimetal and bimetal

Russian bimetallic radiators

Almost every modern house or apartment has a heating system. One of the key roles in it is played by the radiator. It is this heater that is responsible for the heat exchange in the premises. Today, the market offers a wide range of radiators, which differ in the material of manufacture, shape, efficiency and price. The most popular in the domestic market are steel, aluminum and bimetallic products. Each of them has its own strengths and weaknesses. To choose the most suitable steel option, you should listen to the recommendations of experts.

How to choose a steel heating radiator

1. Heating appliances made of steel are of two types: panel and tubular.
2. Panel-type radiators stand out for their simplicity, efficiency and affordable price. They are suitable for owners of private houses, in which the heating system does not create high pressure (up to 10 bar) and heats the coolant to a temperature above 70 ° C. Single-panel models win in price, but two-panel counterparts are considered more powerful. The advantages of this type include ease of installation, cost-effectiveness, elegant appearance, a wide choice. Panel radiators also have disadvantages, the main of which is the low resistance of welds to water hammer. Therefore, in central heating systems, such devices are used very rarely.
3. Tubular radiators have a traditional appearance. They are a set of vertical sections that communicate with each other through the upper and lower collectors. These devices are more expensive, but they can withstand pressure up to 15 atmospheres, they are able to work with a hot coolant (up to 130 ° C), and have a high heat transfer. It is important for the consumer to be aware of some of the shortcomings. This is a low resistance to corrosion (especially with poor water treatment) and mechanical damage.
4. Having decided on the type of steel radiator, you should correctly calculate the optimal dimensions of sections or panels. It is roughly accepted that for heating 1 sq. m requires about 100 W of thermal energy. As for the shape of the radiator, a simple ratio should be followed. The length of the device should be at the level of 60-70% of the window width.
5. When buying a steel radiator, it will not be superfluous to pay attention to the package. The most practical will be models equipped with a thermostat. To quickly shut off the battery in case of leakage, it is necessary to install a ball valve. And the Mayevsky crane allows you to remove air from the heating system in a timely manner.

Our review includes 9 of the best steel heating radiators. All of them have been approved by the expert community and Russian consumers.
