The sizes of bimetallic heating radiators

Selecting the appropriate heating system is essential if you want to keep your house warm and comfortable throughout the winter. Bimetallic heating radiators are particularly noteworthy among the available options due to their high level of efficiency and dependability. Even on the coldest days, you can have a comfortable indoor environment thanks to the uniform heat distribution that these radiators are designed to provide throughout your house.

However, what are bimetallic heating radiators precisely, and why should you think about installing them in your house? In essence, two distinct metals that expand and contract differently when heated are used to construct these radiators. Your home will remain toasty and comfortable in every corner thanks to this innovative design, which enables exact temperature control and effective heat distribution.

The size of the bimetallic heating radiators you select for your house is an important consideration. The radiator’s effectiveness and heating capacity are largely dependent on its size. Making an informed choice that satisfies the heating requirements of your home requires an understanding of the various sizes that are available and how they affect heating performance.

A number of considerations must be made when choosing the appropriate size bimetallic heating radiator for your house. These include your desired level of comfort, the size of the room or space being heated, and the insulation levels in your house. You can make sure that the radiator size you select for your unique heating needs is both efficient and effective by giving these factors careful thought.

Type	Sizes
Panel radiators	Vary in height and length, typically ranging from 300mm to 900mm in height and from 400mm to 3000mm in length.
Compact radiators	Come in various sizes, usually from 300mm to 900mm in height and from 400mm to 3000mm in length.

The sizes of aluminum heating radiators of various brands and models

Many useful things are made nowadays from aluminum. Thus, the radiators made of this metal alloy have already become commonplace in our homes; they heat up beautifully, quickly, and with lightness. That being said, you must accurately determine the size of the aluminum heating radiators before selecting any of these heating devices. Let’s define sizes and learn how to choose them properly.

What you need to know about the size of the radiators and what they affect

The separation between the axes is the first significant dimension. The majority of aluminum radiators that are available for purchase have a 35 or 50 cm gap between the upper and lower collector.

This indicator is 80, 70, 60, 40, and 20 cm in certain models.

Aluminum radiators come in nearly infinite lengths. The radiator’s power increases with length. Take the required number of sections to reach the desired power level. The size, power, and needed power of the aluminum heating radiator section determine the radiator’s overall length.

Use the installation set to dock the radiator with the heating system’s pipes.

• 1. Brackets (2 or 4 pieces) for hanging the radiator on the wall.
• 2. A special crane for pulling excess air (Maevsky crane).
• 3. The key for the crane
• 4. Radiator passes having a diameter of 3/4 or 1/2. They can be left or right.
• 5. Radiator plugs (dull traffic jams).
• 6. Sometimes still dowels for mounting brackets.

Mounting kit for radiators made of aluminum.

An aluminum alloy radiator can be cast or extruded, depending on the manufacturing process.

1. Casting increases the device’s dependability and durability. In this instance, the sections are cast as complete, discrete pieces that are gathered into a single radiator. At the very end, the battery’s lower section is welded.

2. Using extrusion equipment, the heated aluminum alloy is forced through a metal plate that has holes in it, much like in a movie. This enables you to obtain the appropriate shape for an aluminum long profile. It needs to be cut into segments the same size as the radiator after it has cooled. Weld the top and bottom sections after that. In this instance, the radiator cannot be adjusted based on length; the section from it cannot be removed. They are still rare even though they aren’t sold often.

The sizes of aluminum radiators of various manufacturers and their models

The radiator assembly size and the aluminum radiator section size are shown below the tables.

ROVALL aluminum radiators

This company, which is a part of the Sira Group, produces aluminum batteries with 50, 20, and 35 centimeters between collectors. Adapters, plugs, nipples with gaskets (for joining sections), wall installation brackets, and the Mayevsky crane should all be included in the installation kit (separately purchased).

• Maximum working pressure – 20 bar.
• Pressure when testing the device – 37.5 bar.
• Water temperature limit – 110 ° C.

Features ROVALL ALX 200: 200 mm is the distance between the axes.

It is common knowledge that the dimensions of aluminum heating radiators have an impact on their properties. To select radiators for your space that will work best, give this some serious thought.

Dimensions of bimetallic heating radiators: Methods for calculating the number of sections

One significant factor that influences the heating quality of a building is the size of the bimetallic radiators.

Which battery sizes are produced for heating purposes?

Are they all the same, or are there differences between manufacturers?

The sizes of bimetallic heating radiators

The mounting height, depth, and width are the three fundamental parameters that characterize the dimensions of bimetallic radiators.

The width is determined by their number, and the height and depth are determined by the section’s size.

The vertical channel spacing determines the height of the batteries. It has the standard dimensions of 200, 350, and 500 mm for radiators made by all manufacturers.

A segment between the centers of the input and output holes is called the distance between vertical channels. There are differences in the final height, radiator depth, and radiator width (see table 1).

Distance between intercessors The model name includes information about the majority of manufacturers. However, the radiator’s specification indicates a different mounting height.

The radiator’s width based on how many sections there are. Thus, the parameter’s value is 640 mm for an 8-sectional radiator, 800 mm for a 10-sectional radiator, and 960 mm for a 12-sequentary radiator (values for batteries with a section of the section 80 mm).

Calculation of the number of radiator sections

The radiator section’s overall size determines its thermal power. The parameter varies in the range of 0.12-0.14 kW when the vertical axes are 350 mm apart, and in the range of 0.16-0.19 kW when they are 500 mm apart. Thermal power of at least 0.1 kW is needed for the middle lane per square meter of area, per SNiP requirements.

In view of this prerequisite, the formula is applied. To determine how many sections there are:

Where N is the necessary number of sections, Q is the first section’s thermal power, and s is the heated room’s area.

For example, radiators with 140 watt thermal power sections are intended to be installed in the 15 m 2 room. When we change the values in the formula, we obtain:

N is equal to 15.72 m^2 * 100/140 W.

Increased rounding is performed. It is required to install a bimetallic 12-sector radiator due to standard forms.

A more precise computation is obtained by calculating the volume of the room rather than its area in terms of sections. In accordance with SNiP specifications, 41 watts of thermal power are needed to heat one cubic meter of space. With these standards, they obtain:

Where n is the necessary number of sections, V is the heated room’s volume, and Q is the first section’s thermal power.

As an illustration, consider the computation for placing the identical 15 m 2 area and 2.4 m ceiling height. When we change the values in the formula, we obtain:

N is equal to 36 m * 41/140 W, or 10.54.

Once more, a more significant increase is required: a radiator with 12 sections is required.

A private home’s bimetallic radiator width selection is different from an apartment’s. When doing calculations, it is considered Every material used in the floor, walls, and roof construction has a thermal conductivity coefficient.

Selecting sizes It is important to consider the SNiP requirements for battery installation:

• the distance from the upper edge to the window sill should be at least 10 cm;
• The distance from the lower edge to the floor should be 8-12 cm.

Selecting the right size for bimetallic radiators is essential for providing the room with high-quality heating. Every manufacturer has slightly different battery dimensions, which are taken into consideration when making a purchase. Making the right calculations will help you avoid errors.

Bimetallic radiators – characteristics, choice, application

If you read our post about the features of aluminum radiators, you most likely recall that despite all of their advantages, these appliances have a number of serious disadvantages that prevent them from being used to their full potential in urban apartments. We will now discuss their bimetallic equivalents, which can assist in getting around any technical limitations when installing in residential multi-story buildings that are connected to communal heating networks.

The device of bimetallic radiators

The bimetallic radiator looks like aluminum. This is understandable: its external case is made of the same metal and painted with the same paint. It can only be distinguished by weight – here the internal structure of the device is already affected, inside which there are steel inserts that protect aluminum from direct contact with the coolant. It is thanks to them that the sections of the batteries are not exposed to the destructive effect of various impurities that are transferred along with the coolant in the communal network. In addition, steel is much more resistant to the action of acids and alkalis, which are also rich in city heating systems and does not interact with copper pipes and heat exchangers.

Bimetallic heating device utilizing the RIFAR product as an illustration

Other advantageous features of bimetallic radiators stem from the coolant’s passage through a steel core:

• Strength. The limiting pressure that can withstand the body of the bimetallic radiator is 30-40 atmospheres. No hydraulic boards are afraid of such a device;
• Economy. Narrowing of the heat carrier supply channels allows you to achieve an optimal combination of energy consumption for heating and thermal inertia of the radiator;
• Durability. The stability of steel internal cavities to corrosion and destruction allows manufacturers to set a long service life on their products – on average up to 20 years.

When you include in the benefits of aluminum models, like high heat transfer, a sophisticated look, and small size, we can state with certainty that bimetallic radiators are the best option available today for heating an apartment in a city.

The overall size of a bimetallic radiator is crucial when choosing one. Heating units are usually mounted beneath windows to produce a thermal curtain by allowing cold air to flow through the glazing. The radiator needs to match the existing niche and have the features required for heat transfer.

Standard values are used to determine the height of heating radiators. It is possible to produce devices with an interaceal distance of 200, 350, or 500 mm. These figures are usually found in the model’s name.

The radiator section’s measurements

It is important to remember that the center distance only measures the distance between the centers of the input and output collectors; it does not represent the entire height of the case. By extending the interface distance by 80 mm, one can determine the device’s actual height.

Thus, for instance, a radiator with a 350 marking will require about 430 mm, and a radiator with a 500th model, about 580 mm.

Remember that the technical standards stipulate that the device’s body must be at least 100 mm from the window sill and the case must be at least 60 mm from the floor.

The number of sections determines the width of the battery and is derived from the formula by. This will be covered in the section that follows.

Calculation of the radiator

For every type of radiator, the number of sections is determined in the same way.

The power required to heat a 1 m 2 area is approximately 1 kW, depending on the technical requirements for the houses in the middle lane.

The power value of one section is typically indicated by the manufacturer for each battery. This parameter is also sometimes referred to as the section’s heat transfer. Knowing power, the following formula can be used to determine the number of sections:

Where s is the room’s area, Q is the power of a single section, and n is the desired amount.

The majority of bimetallic radiator models have a standard width of 80 mm, and the typical 500 mm section has a heat transfer capacity of roughly 180 watts. As a result, a room the size of ours, for instance, 20 m 2 will require 12 sections for heating, with each section being roughly 1 m wide.

Constructive features

As previously stated, the steel tabs that are positioned on the inner surface of the bimetallic radiator shield the body material from corrosion, setting it apart from aluminum.

Steel tabs can be fitted in various radiator locations, including:

• Various sizes of bimetal radiators

A steel core can only be found in vertical channels in basic models. These are the so-called semi- or pseudo-intimallar radiators; despite their superior qualities over aluminum counterparts, the case’s strength and level of protection are still insufficient;

Section capacity and connecting sizes

The bimetallic radiator’s capacity is even lower than that of aluminum because of the steel inserts that are present inside. On the one hand, this is good, and we’ve already mentioned how the section’s small size is better: less coolant and thermal inertia are needed, which leads to more comfort in the management and energy savings. However, bear in mind that channels that are excessively small may become blocked by debris and mud, both of which are unavoidably present in contemporary heating systems.

The thickness of the steel tab’s walls determines the channel’s width. Better strength and durability characteristics of the radiator are associated with thicker walls, but there are already coolant channels.

The steel inserts in a high-quality bimetallic radiator are the same thickness as the water pipe wall. In this instance, the center distance determines the section’s capacity:

• For a battery with a distance of 200 mm-0.1-0.16 liters;
• For 350 mm batteries-0.15-0.2 l;
• For 500 mm-0.2-0.3 liters.

As can be seen, these radiators have very little coolant volume. For instance, a well-known 10-sequence Rifar heater that stands 350 mm tall can only accommodate 1.6 liters. In addition, he can heat an area that is 80 cm wide and up to 14 m 2. Yes, he is going to weigh 14 kg. This is exactly what a bimetallic radiator is; typically, they weigh 1.5–2 times as much as aluminum.

One section of bimetallic radiators is typically sold. It’s practical because you can purchase precisely the number of sections needed to supply the necessary power. Depending on the model, each section has two input and two output holes with an inner diameter of ¾ or 1 inch. Two of them have the left thread, and two have the right thread for ease of assembly.

Recommendations for choosing a bimetallic radiator

Installing a bimetallic radiator in an apartment located in a city makes sense. It is preferable to purchase an aluminum battery if you live in a private home with your own heating boiler.

It is advised to consider the following features when selecting a bimetallic radiator with the required heat transfer:

1. Operating pressure. It usually does not exceed 15 atmospheres. The radiator must withstand such a load;
2. Power. It is necessary to calculate the number of sections according to the above methodology;
3. Dimensions. The width of the radiator is determined by the number of sections, and the height is determined by the end -line distance. For standard window sills 80 cm high, the 500th model is suitable, if it does not fit-you need to take the 350th modification;
4. The thickness of steel tabs. Make sure she is not too small. The indirect indicator of the thickness of the tabs is the weight of the device;
5. Price. Typically, bimetallic radiators cost at least 15-20% more than aluminum.

Even in the worst of frosts, your home will have plenty of heat if you follow all the instructions and select a good radiator.

The significance of selecting the appropriate radiator size for home heating and insulation is discussed in our article on bimetallic heating radiators. Bimetallic radiators distribute heat effectively, but choosing the right size is essential for best results and energy economy. We go over things like the size of the room, the type of insulation, and the amount of heat needed, stressing the importance of doing accurate calculations to match radiator size to heating requirements. Homeowners can ensure comfortable and energy-efficient heating throughout their homes by making informed decisions by knowing the dimensions of bimetallic radiators and how they relate to heat output.

All about bimetallic radiators

Bimetallic radiator batteries have a unique place among various battery types. Excellent strength and heat transfer indicators can be achieved by combining the advantageous properties of two metals, steel and aluminum. Think about the gadget and its features, and familiarize yourself with the guidelines for selecting and attaching bimetallic batteries.

Device and properties of bimetallic radiator

Bimetallic radiators have a combined structure: the aluminum external part controls the heat transfer quality, while the steel inner part is in contact with the coolant. By distributing the materials in this way, the advantages of both metals can be fully utilized, offsetting their disadvantages.

Bimetallic heating radiators made of aluminum received:

• high heatinity;
• excellent heat transfer;
• A quick reaction to battery temperature.

The batteries’ steel core gave them the following qualities:

• resistance to pressure drops and hydraulic boards;
• resistance to electrochemical influences;
• undemanding to the quality of the coolant;
• Durability.

Bimetallic batteries can withstand the conditions of centralized heating systems perfectly, unlike aluminum radiators.

The following benefits of bimetall batteries can be listed in addition to these advantages:

• high threshold of maximum pressure – 30–40 atmospheres;
• high power with small dimensions;
• economy due to a small cross section of the channels;
• the convenience of the design that allows you to quickly remove the individual sections of the repair device;
• Easily calculated number of sections necessary for high -quality warming up.
• long service life – up to 25 years;
• modern and attractive appearance.

All of these benefits are available with Stout brand bidethal radiators. The largest Russian Rifar plant produces heating devices that are specially designed for use in our nation’s operating environment. At every stage of the production process, every product passes the most stringent inspection. High pressure is applied to the radiator twice: once prior to painting and once following. This ensures that every gadget is 100% reliable.

There are four to fourteen sections that can be used, and they can operate effectively with coolant temperatures up to 135 °C and pressures up to 100 atmospheres. Stout is the greatest option because of its carefully considered logistics system, collaboration with dependable partners and suppliers, and direct manufacturer guarantee and insurance.

Advice: You can determine which bimetallic sectional radiator is in front of you by first determining its weight, as they are nearly identical in appearance to aluminum. Compared to an aluminum analogue, a bimetallic device with a steel core weighs substantially more.

Possible problems during operation

Bimetallic devices offer numerous benefits. Which of their characteristics is responsible for the drawbacks?

1. Despite the possibility of using bimetallic batteries in a system with any coolant, the low quality of the latter negatively affects the duration of the service life.
2. A different expansion coefficient in metals present in the design of the battery can eventually lead to the instability of heat transfer, reduce the strength of the device.
3. The use of low -quality coolant in the coolant system can lead to clogging of the channels, the appearance of corrosion, and the deterioration of heat transfer.

Constructive features

There are two different types of structures for bimetallic batteries.

• Cheaper models differ in the presence of steel core only in vertical channels. Such radiators are sometimes called semicimetallic. Despite the fact that in their characteristics they significantly exceed aluminum devices, they still do not have sufficient strength inherent in full -fledged bimetallic batteries.
• Real bimetallic heating devices have a solid frame made of steel, in the production process, poured under the pressure of aluminum alloy.

Separately, copper-aluminum radiators should be mentioned because they surpass all current battery types in their characteristics. Despite their long service life, good heat transfer, and exceptional resistance to corrosion, their high cost prevented them from being widely used.

The dimensions of the batteries

The device’s dimensions are crucial because, given the required power parameters, it ought to be able to fit in a window niche. Which sizes are possible for bimetallic batteries?

Standard height sizes define bimetallic heating radiators. The center distance of the device—200, 350, or 500 mm—is indicated by a marking on it.

Crucial! It is important to keep in mind that the center distance—which does not equal the case’s height—is the space between the battery’s input and output holes when selecting a radiator. You must increase the center distance by 80 mm in order to determine the device’s actual height.

The device’s total height with various markings:

• Marking 200 – real height 280 mm;
• 350 – the height of the device is 430 mm;
• 500 – height 580 mm.

The number of sections, which is determined by the room’s specifications and each section’s power, will determine the heating device’s width.

Take note! Remember that the radiator must be installed at least 10 cm from the windowsill and 6 cm from the floor in order to comply with technical standards when selecting the radiator’s size.

Calculation of the number of bimetallic batteries

The bimetal radiator has how many sections that can heat the room completely? Bimetallic radiator calculations require an understanding of two parameters:

• how many square meters the area of the room occupies;
• Power of one section of the device.

Construction standards state that about 100 W is needed to heat one square meter of living space. The area value is multiplied by 100 to determine the total power required to heat the room. The power of the chosen radiator’s section is divided into the result.

We will ascertain the number of device sections required for a 25 square meter room. When using a bimetallic device with a 170 W power output in one section.

1. 25 x 100 = 2500 W – required power.
2. 2500: 170 = 14.7 – round to 15 – we get the required number of sections.

You can add 20% of the reserve because obstructions or equipment wear may cause the system parameters to change. Additional sections might be required to heat the apartment on the corner, rooms with lots of windows, and rooms with high ceilings. The necessary number of sections will be more than 1.5–2 times in areas with a harsh climate.

Crucial! Multiple radiators with fewer sections are recommended because batteries with more than ten sections are not sufficiently warmed up.

What to look for when choosing

Find out which features of the bimetallic radiator need to be considered before making a purchase.

1. Operating pressure. The bimetallic sectional radiator must withstand a constant load of 15 atmospheres, for a centralized heating system it is better to choose a device with the maximum value of the working pressure.
2. The nominal power of the section is needed to calculate their number.
3. Dimensions. For standard window sills of 80 cm high, a model with an interaceal distance of 500 mm is suitable.
4. The thickness of the steel tabs. The thicker the walls, the stronger the device and the longer it will last.
5. Price. Bimetallic radiators cost at least 20% more than aluminum. If the price is below, most likely, it is a "semi -bimet" of low quality.

Installation of radiators

Which pipes work best with batteries made of bimetallic materials? Skilled artisans recommend combining reinforced polypropylene pipes with bimetallic heating radiators. Steel and metal-plastic pipes may be used on the zange compounds; however, in this situation, leaks and blockages must be anticipated. The point welding method is the best way to connect because of its dependability.

The radiator under the window is typically positioned precisely in the center, according to tradition. This enables the gadget to produce a heat curtain, which obstructs the entry of cold air through the window.

Which connections are possible for a bimetallic radiator?

• The side or one -way connection has maximum efficiency, but only with a small number of sections (up to 12 pieces). With a larger number of sections, the site remote from the supply pipe will warm up poorly.

• Lower connection is less effective in terms of heat return, it is used only in the case of a specific system configuration.

• Diagonal connection is used for radiators with 12 or more sections and allows you to achieve uniform heating of the device.

Installing adapters for connecting to the pipes and a valve for lowering air or the Maevsky crane is necessary before connecting to each bimetallic battery.

The way the radiator is connected:

1. After dismantling the old equipment using the construction level, marking is made for the installation of a new device, holes for brackets are drilled.
2. The brackets are attached to the wall with dowels and cement mortar.
3. The battery is connected to the supply communications, a crane or thermostat is placed at the connection site.

Crucial! The bimetallic sectional radiator requires the installation of a coarse cleaning filter prior to each battery connection because its small internal channels are easily clogged with debris from the heating system.

The device, selection, and connection guidelines for bimetallic radiators. Both good and bad traits. The number of batteries is calculated.

Selecting the appropriate size for bimetallic heating radiators is essential to guarantee effective insulation and heating in your house. To suit a range of room sizes and heating requirements, these radiators are available in different sizes. It’s critical to take into account elements like the room’s size, the necessary heat output, and the configuration of your heating system.

It’s crucial to balance heating efficiency and visual appeal when choosing the size of bimetallic radiators. Choosing too-small radiators can lead to insufficient heating, which can be uncomfortable in the winter. On the other hand, selecting oversized radiators may result in energy waste and increased heating costs.

Heat output, expressed in British Thermal Units (BTUs) or watts, is a key factor to take into account when sizing bimetallic radiators. This measurement, which is dependent on the radiator’s size, material composition, and the temperature differential between the radiator and the room, shows how much heat a radiator can generate.

Furthermore, the general appearance and performance of your heating system may be impacted by the size of your bimetallic radiators. Oversized radiators could visually overwhelm the space, and undersized ones might not disperse heat efficiently. To guarantee the best possible heating performance, size and efficiency must be balanced.

In conclusion, one of the most important steps in maximizing your home’s insulation and heating is choosing the proper size for your bimetallic heating radiators. Radiators that provide efficient heating while improving the overall comfort and appeal of your living space can be chosen by taking into account various factors, including room size, desired level of heat output, and aesthetic preferences.
