During the cold months, your heating system’s efficiency is vital to keeping your house warm and comfortable. Radiators are typically the most important part of your heating system since they are in charge of evenly distributing heat throughout your room. A thorough understanding of the power and capabilities of each radiator section—especially bimetallic radiators—is crucial to maximizing the efficiency of your heating system.

Bimetallic radiators are a common option in many homes because of their longevity and capacity to hold heat. Bimetallic radiators are built using two distinct metals that expand and contract at different rates when heated, producing effective heat distribution, in contrast to traditional radiators, which are usually made of cast iron. A bimetallic radiator’s individual sections each have a power output that directly affects the radiator’s overall heating capacity.

It’s important to understand the power of a single bimetallic radiator section for a number of reasons. First of all, it assists homeowners in precisely determining how much heat is needed in each room or space of their home, guaranteeing maximum warmth and comfort all around. Homeowners can maximize energy efficiency and reduce heating costs by positioning and sizing radiators strategically by knowing the power output of each radiator section.

Furthermore, homeowners can troubleshoot heating issues more effectively if they are aware of the power of one section of a bimetallic radiator. Knowing the power output of each radiator section can help identify potential issues, such as blockages or malfunctions, if some parts of the house are consistently colder than others. This will enable prompt repairs and maintenance.

We’ll go into more detail about the importance of comprehending the power of a single bimetallic radiator section in this article. We’ll look at how having this information enables homeowners to choose their heating systems wisely, which eventually results in increased comfort, cost savings, and efficiency.

## Power of 1 section of bimetallic heating radiators

Any heating radiator’s primary function is to provide room temperature. For these reasons, the most important factor to take into account when purchasing a radiator is heat output. The heat transfer coefficients for each radiator model, including bimetal, vary. The number of sections and volume have an impact on this parameter.

What is the power of one bimetallic heating radiator section, then? You can accurately determine the required size of the device by knowing the value.

## What is heat output

Heating radiator made of two metals

It only takes two simple words to define heat output: it is the total amount of heat that the radiator emits over a predetermined amount of time. Heat flux, thermal power, and radiator power are names for the same concept, and they are all expressed in Watts. This figure equates to 200 W for a single bimetallic radiator section.

Heat output table for heating radiators

Certain documents contain heat output values that are expressed in calories per hour. Calories can be simply converted to Watts using the formula 1 W = 859.8 cal/hour to avoid confusion.

Three processes result in a room being heated by heat from a radiator:

The act of warming a space

All forms of heating are used by each heater model, albeit in varying amounts. Radiators, for instance, are thought of as those batteries that radiate 25% of their heat energy into the surrounding area. However, these days, the word "radiator" has come to mean any type of heating device, independent of the primary heating mechanism.

Knowing the power of a single section of a bimetallic radiator is essential when it comes to heating and insulating your home. These radiators are long-lasting and provide effective heat distribution because they are made of two distinct metals. Such a radiator’s capacity to efficiently heat a particular space is directly impacted by the power of one of its sections. This power is influenced by elements like size, material, and design, which affects how well heat is distributed throughout your house. Understanding the strength of each radiator section enables homeowners to make well-informed decisions regarding their heating systems, guaranteeing energy efficiency and comfort in every area of their homes.

## Sizes and capacity of sections

Steel inserts allow bimetal radiators to be more compact than their aluminum, cast iron, and steel counterparts. This is somewhat of a good thing because the smaller the section, the less coolant is needed to heat it, making the battery operate more efficiently in terms of heat output. But excessively thin pipes clog more easily with debris and junk, which are an unavoidable part of contemporary heating networks.

Remains and grime within the warming radiator

The inner steel cores of high-quality bimetal radiators are as thick as an average water pipe. The capacity of the sections determines the battery’s heat output, and the capacity parameters are directly impacted by the center-to-center distance:

Based on the information provided above, bimetal radiators need a minimal quantity of coolant. A heater with ten sections, for instance, that are each 35 cm high and 80 cm wide, can only hold 1.6 l. In spite of this, there is sufficient heat flux to warm the air in a 14 square meter room. It is important to keep in mind that a battery of this size weighs 14 kg, nearly twice as much as its equivalent in aluminum.

Most bimetal radiators can be assembled to precisely the right size for the room by buying them in specialty stores, section by section. While there are one-piece models with a fixed number of sections (usually no more than 14 pieces), this is still convenient. There are two inlet and two outlet holes on each component. Depending on the heater model, their sizes may differ. Two holes are made with right-hand threads and two with left-hand threads to facilitate the assembly of bimetal radiators.

## How to correctly select the right number of sections

The data sheet for bimetallic heating devices contains information on their heat output. Do all the necessary computations based on these data. If the heat transfer value is not stated in the documentation, you can view the data on the manufacturer’s official website or use the average value in your calculations. A separate computation needs to be made for every distinct room.

You must consider a number of factors when determining the necessary number of bimetal sections. Given identical operating conditions, bimetal’s heat transfer parameters are marginally higher than those of cast iron. For instance, if the coolant is 90 °C, one section of bimetal will have a power of 200 W, and one section of cast iron will have a power of 180 W.

Table for figuring out the radiator’s heating capacity

If you decide to replace the cast-iron radiator with a bimetallic radiator, the new radiator will warm slightly more efficiently than the old one given the same dimensions. And it’s a positive thing. It is important to remember that as blockages develop inside the pipes, the heat output will gradually decrease. Deposits that form when metals come into contact with water clog batteries.

It is therefore safe to take the same number of sections if you do decide to replace. Batteries with a tiny reserve of one or two sections are occasionally installed. This is done to prevent clogging from reducing heat output. However, you cannot purchase batteries for a new room without first performing calculations.

## Calculation by dimensions

The volume of the room that has to be heated determines how much heat a radiator can produce. More sections will be needed in larger spaces. As a result, figuring out the room’s area is the easiest method.

Plumbing fixtures are subject to specific standards that are tightly governed by SNiP. This also applies to batteries. The typical heating power for buildings in the strip with moderate temperatures is one hundred watts per square meter of space. After calculating the room’s area by dividing the width by the length, the resultant number still needs to be multiplied by 100. This represents the radiator’s overall heat output. All that is left to do is divide it by the bimetal’s heat transfer parameters.

A formula to determine how many sections based on the room’s dimensions

For a 3 by 4 meter space. This is how the calculation will appear: 3x4x100/200 = 6 pieces is K. Although the formula is very basic, it can only be used to approximate the number of bimetal sections. These computations do not account for crucial factors like:

- ceiling height (the formula is more or less accurate for ceilings no higher than 3 m).);
- room location (north side, corner of the house);
- number of window and door openings;
- degree of insulation of external walls.

The recommended temperature of the battery

## Calculation by volume

It is a bit more difficult to determine a radiator’s heat output by room volume. You will need to know the room’s length, width, and height in addition to the heating standards set for one m 3 – 41 watts in order to accomplish this.

For a 3 by 4 m room, what heat output should bimetallic radiators have?.. Considering the 2.7 m ceiling height, we get V = 3x4x2.7 = 32.4 m 3. Once the volume is known, figuring out the radiator’s heat output is simple: 1328,4W = 32,4×41 = P.

Thus, K = 1328,4/200 = 6,64 pieces will be the number of sections (accounting for the battery’s 200 W thermal capacity in the high-temperature mode). In the event that the resultant number is not an integer, it is always rounded upward. More precise computations indicate that you will require 7 sections, not 6.

## Correction factors

Even though the data sheet shows the same values, the actual heat output of radiators can vary based on the circumstances under which they operate. It should be noted that the aforementioned formulas are only reliable for homes with average insulation values and for regions with mild climates; under other circumstances, adjustments to the calculations are required.

Correction coefficients for figuring out how many heating battery sections there are

To achieve this, a coefficient is added to the value that was calculated during the process:

- corner and northern rooms – 1,3;
- regions with extreme frosts (Far North) – 1.6;
- screen or box – add another 25%, niche – 7%;
- for each window in the room the total heat output for the room is increased by 100 W, for each door – 200 W;
- cottage – 1.5;

Crucial! Due to their high cost, bimetallic radiators are rarely installed in private homes, hence the final coefficient in the calculation is rarely used.

Batteries with bimetallic heating

## Effective heat transfer

Values of heat output for radiators are given in the data sheet or on the manufacturers" websites. They are suitable for specific parameters of heating systems. The heat head of the system is an important characteristic that should not be ignored when making the necessary calculations. Usually the heat output value of 1 section is given for a heat head of 60° C, which corresponds to a high-temperature regime of the heating system with a water temperature of 90° C. Such parameters are now found in older houses. For new buildings, more modern technologies are already used, where a high thermal head is no longer required. Its value for the heating system is equal to 30 and 50 ° C.

Schedule of temperatures for the heating system

The power of the sections needs to be recalculated because the technical passport and actual values for the heat head differ. It usually turns out to be less than claimed. The heat output value is divided by the amount stated in the documents and multiplied by the heat head’s actual value.

The way that heating batteries are installed and connected affects how much heat they can produce.

A bimetallic heating radiator’s size and capacity to heat a space are directly influenced by the specifications of its output in one section. Make precise calculations; it is impossible to determine the bimetal’s heat output without knowing its value.

## Power of bimetallic radiators: features of heating and calculation of batteries for one room

This information is primarily meant for people who have made the decision to manually heat their homes. In such cases, they will need to determine the capacity of heaters for each room while also accounting for the ambient temperature.

Naturally, these computations will vary depending on the climate zone, the building’s level of insulation, and the thickness of the double-glazed windows, but all of this is too complex, so we’ll try to break it down into something understandable so you can do these calculations on your own.

Distinctive dimensions of bimetallic batteries

Bimetallic radiators, which are the most widely used for autonomous heating systems, will be the focus of our calculations; among other things, we’ll show you a video in this post.

## Thermal capacity of radiators

### Some features of heating

Heating system with one pipe and two pipes

- When installing autonomous heating, the instruction allows you to install both a single-pipe and two-pipe circuit. But this will change the connection scheme, and this may affect the power of the heater, so let"s find out what both of these options are.
- Let"s start with a one-pipe system and here we see that the coolant moves through a thick pipe, from which there are thinner ones, through which water under pressure enters the heater and returns back.

The price of such a device is less, because you have to heat less water, but there is a serious problem – with each radiator coolant becomes colder and colder, so in such cases it is recommended to do with three or four radiators and no more than that, because they lose their power in the order of distance. - Things are quite different with a two-pipe system – Here, of course, you will have to heat much more water, but it does not lose its temperature when it enters the radiators through the supply pipe, because the cooled coolant is discharged into the return pipe. On such circuits, calculations of the capacity of radiators of different types will be the most accurate.

The area beneath the window is the most efficient location for the radiator.

Note: There should be no warm air leaks in the room in order to maintain the most consistent microclimate possible. This will also help determine how powerful the heaters will need to be. As a result, radiators should be positioned beneath windows, as seen in the image above, where hot air flows will rise and form a "curtain" to prevent cold air from passing through the glass.

### How many radiators are needed for one room

Bimetallic radiator installation

Power table for bimetallic radiators based on brand

Note: When determining the heating appliance capacity for a given room, the type of metal used to construct the radiator is completely irrelevant. In reality, if the device is panelized, the manufacturer will always list the nominal power of each panel or the total device power in the accompanying documentation.

A bimetallic radiator’s section’s power is determined by the manufacturer.

Let us now attempt to compute the power of the radiators based on the area of the room. To illustrate, we will use a 4,55 x 6,5 m room and the formula S*100/P. It should be noted right away that these calculations are only accurate if the ceiling height is not higher than 2,7 m.

The area of the room S is therefore 4,5 * 6,5 = 29.25 m^2. The power required for one section of the bimetallic radiator (P) is GLOBAL STYLE 500 185 W, and the number 100 represents the watts required per m^2 for Moscow and the Moscow region.

We will need to know the number of sections (K) because our room is quite large. Kcount of sections=S*100/P=29,25*100/185=15,81 or 16 sections, which translates to one large or two medium-sized radiators.

Let’s now compute the necessary number of sections from the same manufacturer using the same power in a room with the same area but higher ceilings than 2.7 meters. A height of 3 meters can be used as the calculation unit.

As a result, we must first determine the room’s cubic capacity, or V=4,5*6,5*3=88,5 m3. One cubic meter of space in Moscow and the surrounding areas requires the production of 41 W of heat energy.

Thus, Rob total=V*41=88,5*41=3628,5 W will be the total power required for the room. Therefore, 3628,5/185=19,6 or 20 sections of the bimetallic radiator Global Style 500 if one section has a power of 185 W. This means that there are already two radiators because one would be too large.

However, the accuracy of these calculations depends on the building’s insulation and the absence of drafts in the affected area.

For effective insulation and heating in your house, selecting the proper size and kind of radiator is essential. Because of their reputation for longevity and heat conductivity, homeowners frequently choose for bimetallic radiators. However, to maximize the performance of your heating system, you must comprehend the power of one section of a bimetallic radiator.

A bimetallic radiator’s capacity to emit heat when filled with hot water is referred to as its one section’s power. Numerous elements, such as the radiator’s size, design, and material composition, affect this power. Larger radiators with more sections typically have higher power output, which enables them to heat larger spaces more efficiently.

Finding a balance between power and efficiency is crucial, though. While undersized radiators might find it difficult to heat a room sufficiently, oversized radiators can cause overheating and energy waste. You can find the right radiator section size and number for maximum comfort by calculating the heating requirements of each room in your house.

Furthermore, optimizing the power of your bimetallic radiator is largely dependent on proper installation and maintenance. Proper placement and clearance of obstacles around the radiator facilitate effective heat distribution in the entire space. Furthermore, routine cleaning and inspection help avoid problems like corrosion or obstructions that can lower the radiator’s efficiency.

In conclusion, effective insulation and heating in your home depend on your ability to comprehend the power of one section of a bimetallic radiator. You can create a comfortable living space while reducing energy consumption and costs by choosing the correct size and type of radiator and following the right installation and maintenance procedures.
