Bimetallic heating radiators Technical characteristics

Heating systems are essential to maintaining a warm and comfortable environment in our homes. Radiators are among the many parts of a heating system that are frequently used to evenly distribute heat throughout a home. Bimetallic heating radiators have become more and more popular in recent years because of their superior performance and creative design. For homeowners who want to increase the efficiency of their heating system, it is imperative that they comprehend the technical specifications of these radiators.

Bimetallic heating radiators are a particular kind of radiator made of two distinct metals, most commonly aluminum and steel. This special design offers longevity and durability in addition to effective heat distribution. Your home’s heating system will operate more efficiently because the aluminum promotes heat transfer and the steel offers strength and structural integrity.

Thermal conductivity is one of the main technical features of bimetallic heating radiators. The term "thermal conductivity" describes a material’s capacity to transfer heat. Bimetallic radiators facilitate faster heat transfer from the radiator to the surrounding air because the aluminum component usually has a higher thermal conductivity than the steel component. As a result, rooms can achieve the ideal temperature faster, which will make people more comfortable.

The radiator’s surface area is another crucial factor to take into account. In order to enhance heat dissipation, bimetallic radiators are made with as much surface area as possible in contact with the ambient air. Even in large spaces, this design element ensures effective heat distribution throughout the space, removing cold spots and offering constant warmth.

When selecting heating systems for your house, efficiency is a key consideration, and bimetallic radiators perform exceptionally well in this area. Their creative design lowers energy consumption while improving heat distribution. Bimetallic radiators provide maximum comfort while reducing energy costs for homeowners by heating up rapidly and keeping temperatures constant.

The parameters and technical characteristics of bimetallic heating radiators

In a contemporary home, batteries are an essential component of the heating system. But the correct radiator selection is essential for efficient heating. Bimetallic heating radiators are highly popular due to their positive technical characteristics. The two-layer walls of this kind of radiator, which are made of two distinct metals, gave rise to its name. However, the market is seeing an increasing number of new bimetallic radiator models with increasingly sophisticated features.

When considering bimetallic heating radiators, it"s essential to understand their technical characteristics to make informed choices for your home"s heating and insulation needs. Bimetallic radiators consist of two different metals combined to optimize heating efficiency and durability. Typically, these radiators are constructed using steel and aluminum layers, offering a balance of strength and heat conductivity. The steel core provides robustness, while the aluminum exterior ensures quick and efficient heat distribution. This combination results in radiators that heat up rapidly, providing warmth to your space efficiently. Additionally, bimetallic radiators are often more resistant to corrosion, prolonging their lifespan and reducing maintenance needs. Understanding these technical aspects can help homeowners make informed decisions when selecting heating systems for their homes, ensuring comfort, efficiency, and durability.

Specifications

It is important to recognize the primary attributes of bimetallic heating devices, which can be differentiated in multiple ways:

• The heat transfer of this radiator is quite large, namely about 100-190 watts. Aluminum shell has good heat transfer.
• Radiator pressure indicator. The working pressure of bimetallic radiators can be up to 40 atm. This is explained by a strong design, that is, a steel core. In order for the rupture of this core, the pressure should be at the level of 90 atm. It can be concluded that the radiator of heating is bimetallic, the pressure characteristics of which are large enough can work in extreme situations, namely with hydraulic houses.
• Temperature regime. This indicator can reach up to 1000C or more.
• The bimetallic battery has high resistance to corrosion processes. According to this parameter, the most effective are the devices with the core of stainless steel.
• An important characteristic of bimetallic radiators is their aesthetic appearance. In its form, and the front panel, radiators are approaching any interior.

Bimetallic devices are primarily characterized by their effectiveness and reliability.

However, it is important to remember that these characteristics are completely built into the goods made by reputable companies that have made a name for themselves in the industry. As an illustration, consider the Italian brands Global Style, Sira, Rifar, and Royal Thermo. These manufacturers typically offer a 10–15 year guarantee on heating devices. Renowned manufacturers produce high-quality radiators with elegant designs and compact specifications.

Device

The bimetallic heating radiator has two layers of equipment:

• The inner layer is a steel core consisting of the upper and lower manifolds, which has an N-shaped shape (rice. 2). The collectors are connected by the pipe by the heat power supply – it is along this pipe that the coolant goes. The internal metal structure is ideal for the heating system, that is, it holds pressure well.
• The outer layer is a decorative shell that is made of several plates (in the form of sections) or in the form of a continuous panel (rice. 2).

Rice. 2 radiators with a bimetallic design

Hermetic fasteners are located inside the bimetallic heating device’s sectional structure. One big benefit of this design is that the radiator can be made larger or smaller.

The bimetallic device’s thermal properties are also present in the manufacturing materials. Two categories exist:

• Copper and aluminum. This type of radiator has quite good characteristics. Copper has high thermal conductivity, does not lend itself to corrosion processes. This device also has great power.
• Steel and aluminum. This option of manufacturing radiators can be without a core in the form of pipes, but simply with steel channels reinforced. This option has greater heat transfer. And there are no cloths in this design.

The channels in bimetallic heating batteries have a tiny pattern diameter. This implies that only a tiny quantity of coolant is needed. This is a big benefit for the heating system’s effective operation because it will make using the thermostat’s features simple. The bimetal-type heating devices work on a rather complex technology. This is casting that is being affected by intense pressure. Spot welding is also used in the construction of some models.

Bimetallic heating batteries are formed by welding in addition to threaded nipples connecting the sections. Greater temperature and pressure in the heating system are tolerated by the welding connection. The temperature can reach up to 1350C in welding models and 1100C in nipple models.

Disadvantages of equipment

There are certain drawbacks to the properties of bimetallic radiators. Specifically:

• The main drawback is the high price of this product. Bimetallic type batteries are much more expensive than cast -iron.
• Often bimetallic models are lended in corrosion processes in the presence of air in the system, for example, when in multi -storey buildings they lower water from the system in a non -feeding season or during accidents and repairs. As well as corrosion progresses if antifreeze is used as a coolant.
• The disadvantages include a small passage of inter -collection pipes.

A few considerations must be made in order to select the best bimetal radiator, the technical attributes of which will be appropriate for a particular heating system. The pipeline’s diameter, which connects to the battery, needs to be known.

Making a calculation and figuring out how much power (heat transfer) is required is also crucial. The size of the room must be considered in this situation. Prior to purchasing such a costly heating system component, you should thoroughly research and ascertain the material that radiators are constructed of. that is, the device’s design and the material’s strength. The system’s pressure indicators are to blame for this.

It is also crucial for the aesthetic species. You can select the hue and design that best fit the interior of the home or apartments. When selecting a bimetal heating radiator, the parameters’ features need to adhere to fire safety regulations. Therefore, there should be a 15 cm indentation from the floor to the window.

The radiator’s size is determined by measuring the intersexis distance (rice.3), which is the distance between the upper and lower collector. There is a 20–80 cm range in the center distance. Large values are only appropriate for interior or size-appropriate rooms.

Other computations include those for the battery section’s height, width, and depth (rice, 3). The value of height is typically 8–10 cm greater than the center distance. Although the width of the device’s section varies depending on the manufacturer, it typically measures about 8 cm. The section’s depth typically ranges from 8 to 10 cm. However, if the device is taller, it might be lower.

The choice of thermal power

The bimetallic radiator’s technical specs, specifically its center distance and thermal power (W), match one another.

• 100 W – 20 cm;
• 100-145 W-30 cm;
• 120-140 W-35 cm;
• 179-200 W-50 cm.

This technical feature allows you to determine the number of sections that must be purchased for a specific radiator model.

Rice. Four bimetallic radiators with varying sizes

Given the high cost of these heating devices, it is important to accurately determine the number of sections required in order to avoid overspending.

To perform this computation, the subsequent details will be required:

• The area of the room (m2) – s;
• Power of one section of a particular radiator model – N;

The formula therefore reads as follows: (s* 100)/n = the number of sections (pieces).

For instance, the room is 15 m2, and one battery section has a power of 160 watts. (15*100)/160 = 9.3 is the calculation.

It turns out that you need 10 sections of the bimetal heating device in these parameters, so you must round the resultant number to a larger value. However, the amount of windows in the space should also be considered; if there are more than one, then one or two more sections should be added. It is best to get in touch with knowledgeable experts who can perform the accurate calculation while accounting for all the technical details and the house’s heat loss.

Which are the best bimetallic heating radiators?

Bimetallic heating radiators: technical specifications, advantages and disadvantages

A modern interior design, cozy furniture, eye-pleasing color combinations and textures, and a comfortable room temperature are all important components of a cozy home. Russia’s climate dictates its conditions; buildings must be heated for nearly half the year, so selecting a heating method is not a frivolous but rather a strictly practical one.

The traditional cast-iron heating battery has been replaced by a bimetallic radiator, a more contemporary design.

The name "bi" (which means "two" in Latin) refers to the combination of two metals that give the device its high characteristics. Radiator sections are made of copper aluminum or steel aluminum. The structure may have reinforced steel channels or be supported by a steel frame.

Which should I select? Does the cost of a steel and copper radiator differ from one another? Are they appropriate for use in home heating networks given their erratic pressure? We aim to address these queries as well as others.

The pros and cons of the bimetallic heating batteries

Bimetall radiators are different from common aluminum ones in that they have steel interior components and don’t have certain drawbacks.

Two-metal battery

• high heat transfer;
• mechanical strength, resistance to hydraulic boards and high pressure;
• the immunity of metal elements to corrosion;
• a small amount of the coolant used;
• The sectional structure used in many models allows you to easily add or remove sections;
• Modern design that allows the device to harmoniously fit into the interior of any room;
• light weight;
• long service life.

To pay in cash and in kind for effectiveness and superior quality:

• Firstly, this is the most expensive type of radiators in the market.
• Secondly, they have one feature: from time to time they make a characteristic sound similar to a click. This is due to the difference between the temperature expansion of steel and aluminum.

It is possible to compare bimetallic batteries with models made of different materials in the article "The Best Heating Radiators."

Design features

Inside the aluminum corps are steel channels.

The bimetallic battery has an extremely straightforward and efficient structure.

The interior, composed of copper or steel, allows the coolant to flow freely. Butter, antifreeze, and, most of the time, regular water can serve as a coolant.

The layout separates two categories of radiators:

These batteries only use steel tubes to reinforce the vertical channels; it is not possible to completely exclude aluminum and water contact.

Coolant does not come into contact with aluminum as it passes through steel tubes.

The radiator weighs less because of the aluminum tubes, but the metal is prone to corrosion. The second type of models is less prone to corrosion and is more robust.

Properties of compositional material

The advantages of using two different types of metal at the same time can be combined, which improves the device’s heating capabilities.

The device’s external aluminum component has exceptional thermal conductivity (236 W/(M • K)). The water capacity is between 250 and 460 ml. Aluminum serves an aesthetic purpose in addition to transferring heat.

47 W/(m • K) is a comparable steel parameter, for comparison.

The tasks placed before the steel account for its low coefficient of thermal conductivity: it must withstand pressure, guarantee resistance to corrosion and hydraulic boards, and function as a rigid internal frame for the entire structure.

Some models use copper instead of steel.

A robust oxide layer that forms on a copper tube’s surface guards against exposure to chemicals found in coolant and corrosion.

Another benefit of copper is that it has a low coefficient of roughness inside the tubes, which keeps precipitation from depositing. The internal section is lowered by precipitation, which lowers the tubes’ throughput.

Copper has an extremely high thermal power of 401 W/(m • K). These radiators have better heating capabilities.

Specifications

We provide the technical specs of bimetallic heating radiators from various Russian and international manufacturers as an example. The models that are being presented have a center distance of 500 mm.

Table of comparisons for well-liked models

All rates are approximate and valid as of the end of 2014.

The table indicates that, except for the working pressure parameters in the Rifar Monolit, the characteristics of steel and aluminum batteries are similar. Because the number of sections cannot be independently changed in a monolithic structure, a high pressure indicator is produced.

Since the heating system pressure in apartments can be extremely high, monolithic frame radiators are the best option for high-rise buildings.

Comparing the Italian manufacturer Sira’s model to its Russian counterpart, it is slightly lighter.

Mars-500, which uses copper instead of steel, is slightly more expensive. The smaller weight and more compact size are apparent right away.

A product’s service life can be determined using dozens of factors. The flow of sections in joint locations will probably malfunction first, but this won’t happen before five to ten years have passed. Put another way, the radiator will grow weary of you before its service life ends.

Whichever option you select, the battery from Bimetal will delight you for many years with its contemporary design and cozy warmth throughout the house.

Accurately calculating the number of heating radiator sections is essential to achieving the ideal temperature regime within the rooms. Calculation options and formulas are presented in the article.

Characteristics of modern bimetallic radiators

Design features and varieties of bimetallic radiators

When discussing this type of radiator’s design, we choose two primary components: aluminum panels and steel pipes. These products’ designs are composed of them. This guarantees heat transfer’s efficacy. When hot water flows through the aluminum shell of a bimetallic radiator, the core, whose properties are crucial to any consumer, heats the aluminum shell. Heat is transferred from them to the surrounding air.

In addition to adding to the attractive design of bimetallic radiators, the aluminum shell facilitates efficient heat transfer. Additionally, because aluminum is a lightweight metal in and of itself, the battery has a slight weight. This adds even more comfort to the installation of these products. The intricate shape of the bimetallic battery’s body contributes to its excellent heat transfer properties and is positively reflected in the product’s appearance.

Simply consult the product passport to become familiar with the bimetallic radiator’s technical specifications. They might differ from one another. Everything is based on the model. Another significant element influencing the product’s qualities is the manufacturer.

Stores currently carry two varieties of bimetallic radiators:

• radiators that are 100% bimetallic. How should this be understood? Such products have a steel core of pipes. which surrounds the aluminum shell. Their main technical characteristic is increased strength. In the process of their operation, the occurrence of leaks is excluded. Such radiators are produced mainly by Italian companies: Global Style and Royal Thermo Biliner. Domestic companies are also engaged in the production of bimetallic batteries, for example, Plantekhprom BM;
• semi -bimetal radiators – products that are only half bimetallic. Steel in their manufacture is used only for pipes. They enhance the vertical channels of these batteries. In this case, aluminum partially contacts water. Their main advantage is that They are 10% better. Compared to bimetallic ones, they give heat. Their other plus is lower by 20% price.

The following businesses are involved in the distribution of these radiators:

Even after comparing the technical specs of these two product types, experts are divided on which is the better choice for an autonomous system in a private home and which is more appropriate for a centralized heating system.

He is not afraid of chemistry, which is one of the key qualities of a bimetallic radiator that makes it an excellent choice for a centralized heating system. which is included in the city’s water services. But at very high pressures, aluminum clearly outperforms steel. The experts all agree on one thing: making bimetallic batteries is the better option when replacing the radiator in a home with older heating pipes.

Sectional or whole?

Bimetallic radiators typically have a specific number of sections. Put differently, during the course of producing the product Initially, a completely new section is created. and after that the necessary number of sections are linked together. Nipples serve as a means of anchoring.

Take note that complete metal batteries are available in addition to sectional radiators. The desired sized core is made right out of the steel. After that, an aluminum figure shell is placed over it. The completed bimetal battery exhibits superior qualities. Even at 100 atm of pressure, there is no chance that it will explode while in use.

In detail about the characteristics of bimetallic heating radiators

Once you’ve found the right radiator model at the store, take your time paying for it. Request from the vendor Battery technical passport Additionally, carefully read the heating radiator’s technical specifications. We will discuss the parameters mentioned there in more detail.

Heat transfer

Heat transfer is the bimetallic radiator’s most significant technical feature. Watts are the unit of measurement for the heat the radiator produces at 70C coolant temperature. When discussing this parameter’s average value, it typically ranges from 170-190 watts.

Spended pressure during operation

Depending on the model, it ranges from 16 to 32 atm for these kinds of heating devices. Another crucial factor is the product’s maker. The maximum working pressure in an autonomous heating system is 10 atm, and it is limited to 14 atm in centralized heating systems. To prevent radiators from rupturing due to elevated pressure This parameter is indicated by the manufacturer who has a margin. in radiators made of two metals.

Intercessor distance

Knowing the distance between the radiator’s upper and lower collectors is customary. The following millimeter values—800, 500, 350, 300, and 200—are considered standard. It is possible to select a battery model that precisely fits into the apartment’s pipe wiring thanks to the various values for this parameter.

The maximum temperature of the coolant

The coolant in bimetallic radiators can withstand temperatures as high as 90C. Certain manufacturers claim that their products can function properly even when there is water circulating within them that is 95 degrees Celsius or higher. However, one should not take such claims seriously. Particular consideration should be given to this parameter when selecting a heating device. because the heat transfer coefficient is impacted.

Reliability and life span

We can declare with confidence that you can use bimetallic radiators in your apartment for 20 years, given their characteristics. They don’t need to be maintained in this situation.

The ease of installation

The bimetallic battery is composed of exactly the same sections. This allows them to be installed even to the left of the heating battery, or at the very least to the right of it. There are locations where pipe pipe is joined to pipe. Proceeding from the opposite end, install the plug. The Maevsky crane, which is mounted on the side, completes it. There’s an additional plug on the bottom.

A lot of people are familiar with Mayevsky’s crane. It’s a pretty handy invention. The system might happen during the first few weeks of the heating season. The air pipes stay cold because of the batteries inside of them. The Maevsky crane can be used to remove extra air from the radiator. It is not necessary to turn off the riser completely in this instance. This device’s primary benefit is that bullying in pipes can be eliminated without the assistance of masters.

Not only do heating radiators with Maevsky cranes appear in stores, but items with pipes on the underside are also available. A thermostat and valve are connected to them during the battery installation process. The latter regulates the room’s air temperature.

Keep in mind that every bimetallic radiator comes with Maevsky’s crane, plugs, and nozzles. Besides them, it has brackets that let you guarantee a sturdy battery fastening on the wall.

Bimetall radiators disadvantages

Bimetallic batteries have drawbacks just like other kinds of radiators. We highlight the following as some of the most noteworthy:

• The price is the main minus of bimetall products. The cost of their acquisition in comparison with cast -iron heating devices are very high. But they have a more pleasant appearance. These heating devices Easily embed in a modern interior. And in terms of the duration of the operation period, all other types of heating products are ahead of the period;
• The other minus of these products is weakly resistant to corrosion of the core of these radiators, which is made of steel. This happens under the influence of water and air. Rust on bimetallic radiators may also appear under the influence of antifreeze, which, as a coolant in autonomous heating systems, is used by owners of private houses. If the choice was made in favor of such a coolant, then the best solution is aluminum batteries.

For homeowners looking for reliable and long-lasting heating systems, bimetallic heating radiators present an appealing option. Compared to conventional radiators, their special design—which combines steel and aluminum—offers a number of advantages. Bimetallic radiators provide uniform warmth throughout your house thanks to their rapid heat transfer speed and corrosion resistance.

The outstanding thermal conductivity of bimetallic radiators is one of their main advantages. These radiators heat up quickly thanks to the steel and aluminum combination, which evenly distributes warmth throughout rooms. This implies that you won’t have to wait a long time for your heating system to reach the ideal temperature to enjoy a comfortable living space.

Bimetallic radiators also have exceptional longevity. Strength and structural integrity are provided by the steel core, and corrosion resistance is provided by the aluminum coating. This implies that you won’t need to replace or repair your bimetallic radiators as often because they will be able to endure regular use and maintain their functionality over time.

Apart from their longevity and effectiveness, bimetallic radiators also provide flexibility in terms of installation. These radiators, which come in a variety of sizes and styles, fit in well with a wide range of home decor styles and heating systems. Whether you’re building a new home or remodeling an existing one, bimetallic radiators offer flexibility to meet your unique heating needs.

In general, homeowners wishing to improve the comfort and effectiveness of their heating systems will find that bimetallic heating radiators are a compelling option. These radiators promote a warm and inviting home atmosphere over time with their quick heat transfer, robustness, and adaptability.
