Power of steel heating radiators table

Selecting an appropriate heating system for your house is essential for both energy efficiency and comfort. Steel radiators are a common heating option because of their longevity and capacity to evenly distribute heat throughout a space. Making an informed choice for your home’s heating requirements can be aided by knowing the capabilities of steel heating radiators.

Steel radiators are available in a variety of sizes and forms, but their capacity to produce and hold heat effectively is what makes them unique. Steel radiators heat up quickly in contrast to conventional cast iron radiators, enabling you to heat your house more quickly. Steel radiators are also more space-efficient because of their increased lightweight and compactness.

A number of factors need to be taken into account when selecting the appropriate size and power of steel radiators for your home. The amount of power your radiators need to produce depends on a number of factors, including the size of the room, the amount of insulation, and the desired temperature. You can guarantee energy efficiency and effective heating in your home by choosing the right size and power output.

In addition to being effective at heating your house, steel radiators are strong and long-lasting. These radiators are made of premium steel and are meant to last a lifetime. Steel radiators are an affordable heating option for your house because they can last for many years with proper maintenance.

This post will discuss the benefits of steel heating radiators and how you can use them to save energy costs while creating a cozy and warm living area. The advantages of steel radiators can help you make the best decision for your house, whether you’re remodeling or trying to replace your heating system.

How to find out the power of steel heating radiators: their features

What could be more annoying in the winter than pricy, chilly batteries?

When replacing an outdated heating system, people occasionally wonder which heaters to install rather than figuring out how to measure the panel radiator’s power and confirm it using the system’s coolant and pressure levels.

You can only select the appropriate radiators for the space if you have a clear understanding of heat transfer and the factors that affect its intensity.

The property of heat transfer

The fundamental idea behind how steel heating radiators and all other heaters function is what gives them their power:

  1. The coolant, falling into the battery, circulates through the tank (in steel panel models – these are channels), while in hot condition it is directed upward, while when cooling it goes down. In an autonomous or centralized heating system, a boiler is engaged in heating the carrier.
  2. During the time that hot water is in contact with the radiator, she gives him her warmth, heating his walls. This moment is very important, since the size of the heater depends on how long its path will be, and the longer it is, the hotter the radiator.
  3. Heated wall walls give their temperature to the air, which spreads through the room under the influence of heat flows.
  4. To increase the level of heat transfer, manufacturers “supply” the heating device with heat exchangers, as can be seen from steel radiators like 11, 22 and 33.

Heat exchangers, which use two heating principles—a radiator that uses the heat from the device’s walls and convectors that create the movement of heated air—significantly increase the power of steel radiators when they are present.

The power indicators are typically indicated by the manufacturer in the technical passport, which you can use to navigate it. However, it is best to independently calculate the numbers while accounting for the room’s area, air temperature, and number of heat loss.

The following are the effects of choosing the wrong heater:

  1. The so -called flooding, when the room is so hot that you have to keep the window open. This creates a microclimate that is harmful to the body, forces to pay more for energy consumption or install thermostats to reduce the load on the system.
  2. If the power of panel steel heating radiators below the required level, then the room is cold even with their maximum load.
  3. Strong pressure drops in the heating system equipped with weak batteries will lead to an accident, since they will not withstand such “stress”.

If you understand precisely what influences the heat transfer of heating batteries and how to increase their effectiveness, you can prevent all of these issues.

What affects heat transfer

When selecting a heater model, you will require a steel radiator power table, which should be supplied to customers by the manufacturer or sales consultant.

There are a few subtleties that are part of them that you should also consider:

  1. Before buying new heating batteries, you should ask what temperature of the coolant in the system. The hotter it is, the higher the radiator will be heated, which means that the heat transfer will be greater. Having learned the exact temperature, you need to compare it with the indicators of the selected model, which are indicated in the technical passport. For safe and efficient work, they must match.
  2. The size of the radiator matters. The larger it is, the longer the carrier is in it, and from this its walls become hot.
  3. Thermal conductivity of the material is also important. In this case, we are talking about sheet steel no more than 1.5 mm thickness, which indicates the ability to quickly heat up.

These subtleties make up the power of panel radiators, so all of their parameters should be considered when computing.

We examine the effectiveness and heat output of steel radiators, which are frequently used to heat homes, in our article on the "Power of Steel Heating Radiators Table." An extensive summary of the various steel radiator models, their power output, and their suitability for different room sizes is given in this table. To ensure maximum heating efficiency and comfort in your home, it is essential to understand the power of steel heating radiators. This will help you choose the best radiator for your needs.

Features of steel batteries

Panel radiators are constructed from two stamped steel sheets joined together; within, there are three vertical canals for every 10 centimeters of length and two horizontal canals at the top and bottom.

The narrowness of these channels is the weak "link" in these heaters, which is why pure coolant is crucial. This is not feasible with a centralized heating system; instead, you must install the filter at the coolant input to the apartment supply when you choose steel radiators.

Generally speaking, the kW of steel radiators varies according to type and averages 0.1-014 to the following section:

  1. For type 11. which consists of one section and convector at a depth of 63 mm, the power is 1.1 kW.
  2. For type 22. consisting of two sections with two convectors at a depth of 100 mm – this is 1.9 kW.
  3. 33rd type recognized as the most effective, as it consists of three sections with three convectors at a depth of 150 mm. The power of the panel steel radiator of this type is 2.7 kW.

Convector-equipped buildings, for instance, were chosen because steel panels are useless without them and work well with tiny self-sufficient heating systems.

Before making a purchase, familiarize yourself with the following parameters to help you make the best decision:

  1. How many kW in 1 section of a steel radiator.
  2. How does the height and length of the product affect its power.
  3. How many sections and convectors in it.

You can only select the ideal heater option for each room independently after you have the answers to these questions.

Calculation of the power of steel heating radiators

There are numerous models of heating devices with varying dimensions and power indicators available in the consumer market today. Steel radiators should be highlighted among them. These gadgets have good heat transfer, a sleek design, and are fairly light. The power of steel heating radiators must be determined using the table prior to selecting a model.

Varieties

Steel heating radiator types

Think about the steel panel-style radiators, which vary in size and power output. The devices may have one, two, or three panels. Nuting, or corrugated metal plates, is another crucial design element. The devices are designed using multiple combinations of panels and nuts to obtain specific thermal return indicators. You need to become familiar with each type of heater before deciding which one is best for providing the room with high-quality heating.

Steel radiator types that are most common

The following types of steel panel batteries are represented by them:

  • Type 10. Here the device is equipped with only one panel. Such radiators have light weight and the lowest power.

Type 10 steel heating radiators

  • Type 11. Consist of one panel and laying plate. Batteries have a slightly large weight and dimensions than the previous type, differ in increased parameters of thermal power.

Type 11 steel panel radiator

  • Type 21. The radiator design has two panels, between which there is a corrugated metal plate.
  • Type 22. The battery consists of two panels, as well as two wallets. In size, the device is similar to radiators of the 21st type, however, compared to them, have a greater thermal power.

Type 22 steel panel radiator

  • Type 33. The design consists of three panels. This class is the most powerful in thermal giving and the largest in size. In its design, 3 laying plates are attached to three panels (hence the digital designation of type – 33).

Type 33 steel panel radiator

The device’s height and length can differ for each of the types that are being shown. The device’s thermal power is determined by these indications. You cannot compute this parameter on your own. Nonetheless, every panel radiator model passes the relevant manufacturer tests, and the outcomes are all recorded in unique tables. Selecting the right battery for different kinds of rooms is very convenient.

Power determination

Building on the room’s thermal loss indicators is required for an accurate thermal power calculation. This is where the devices will be installed.

A table to determine the quantity of radiators per square meter

The SNiP (construction standards and rules) can serve as a guide for standard apartments. It includes information on heat volumes per unit area, measured in meters squared.

  • In panel buildings, 1m3 requires 41W.
  • In brick houses, 34 watts are consumed for 1m3.

You can determine the power of steel panel heating radiators using these standards.

Consider a room in a typical panel house that is 3.2 by 3.5 meters in size and has ceiling heights of 3 meters. First, we calculate the room’s volume, which comes out to be 3.2 * 3.5 * 3 = 33.6 m^3. Next, look up the numerical value that matches our example in the NNUP norms: 1377.6W is equal to 33.6*41. We consequently got the necessary heat to heat the space.

Extra options

The middle climate zone’s conditions are taken into account when compiling SNiP regulations.

Microclimate characteristics in the SNiP-installed premises

You must use coefficients to modify the indicators in order to compute in regions with colder winter temperatures:

The number of exterior walls must be considered when calculating thermal losses. The indicators of the room’s heat loss increase with their number. For instance, we use a coefficient of 1.1 if the room has a single outer wall. The coefficient will be 1.2 or 1.3 if there are two or three external walls, respectively.

How much warmth is appropriate for the battery

Think of an illustration. Assume that the area experiences an average temperature of -25 °C throughout the winter and that the room has two exterior walls. The results of the computations are: 1378 W * 1.3 * 1.2 = 2149.68 W. 2150 watts is the final result, rounded. It’s also important to take into account which rooms are on the upper and lower floors, the materials used to construct the roof, and the insulation used in the walls.

Calculation of Kermi radiators

You should choose the manufacturer of the device that will be installed in the room before calculating the thermal power. It goes without saying that the industry leaders have earned the best recommendations. Now let’s look at the table from renowned German manufacturer Kermi, which will serve as the foundation for all the necessary computations.

Consider the Thermx2plan, one of the newest models. You can see from the table that each Kermi model’s power parameters are listed, so all you have to do is choose the appropriate device from the list. It is preferable to take a slightly more calculated value in the field of heating since it is not necessary for the indicators to line up perfectly. in order for you to have the stock needed during times of severe cooling.

Kermi Thermi X2 Plan-K Radiator

Red squares in the table indicate the presence of each appropriate indicator. Assume that the radiator height that works best for us is 505 mm, as indicated in the table’s upper section. A 1005 mm-long type 33 device is the most desirable choice. If you need a shorter device, focus on models that are 605 mm tall.

Recalculation of power based on the temperature regime

However, the data in this table are registered for indicators of 75/65/20, where 75 ° C is the temperature of the wire, 65 ° C – the temperature of the drive, and 20 ° C – the temperature that is maintained in the room. Based on these values, the calculation is made (75+65)/2-20 = 50 ° C, as a result of which we get a temperature delta. In the event that you have other system parameters, you will need to recalculate. For this purpose, Kermi prepared a special table, which contains the coefficients for adjustment. With its help, you can make a more accurate calculation of the power of steel heating radiators according to the table, which will allow you to choose the most optimal device for heating a particular room.

Imagine a low-temperature system with the indicators 60/50/22, where the wire temperature is 60 °C, the drive temperature is 50 °C, and the room temperature is 22 °C. The temperature delta is computed using the well-established formula: (60+50)/2-22 = 33 °C. Next, we locate the conducted/diverted water’s temperature indicators by looking at the table. We discover the required coefficient of 1.73 in a cage with a supported room temperature (it is indicated in green in the tables).

Next, multiply the room’s total thermal losses by the coefficient (2150 W * 1.73 = 3719.5 W). Next, we go back to the power table to look at appropriate choices. In this instance, a more modest option will be made because much more potent radiators will be needed to provide high-quality heating.

Conclusion

As you can see, without knowledge of specific indicators, it is impossible to calculate power for steel panel radiators correctly. It is essential to ascertain the room’s heat loss, identify the battery’s manufacturer, and know the room’s maintained temperature in addition to the temperature of the conducted and diverted water. These indicators make it simple to choose the right batteries.

Steel panel radiators: types and power determination

Steel panel radiators are a rival to the typical sectional heating units. Their greater heat transfer coefficient makes them more appealing than all sectional models with smaller dimensions. consist of panels where the formed strokes allow the coolant to flow. One, two, or three panels are possible. The second part consists of the corrugated metal plates, also known as the nut. A high degree of heat transfer of these devices is achieved at the expense of these plates.

Steel panel radiators come in various power and size ranges.

Multiple versions of the panel and nuting are combined to achieve varying thermal powers. Every choice has a distinct power. You must be aware of each of them in order to select the appropriate size and power. The following types of steel panel batteries are used in structures:

  • Type 33 – three -panel. The most powerful class, but also the most dimensional. It has three panels, to which three laying plates are connected (therefore 33 is indicated).
  • Type 22 – two -panel with two laying plates.
  • Type 21. Two panels and between them one plate with corrugated metal. These heating devices with equal dimensions have lower power compared to type 22.
  • Type 11. One -panel steel radiators with one layer of nuting. Have even lower thermal power, but also less weight and dimensions.
  • Type 10. In this type there is only one panel with the coolant. These are the smallest and lightest models.

Each of these varieties may vary in length and height. It goes without saying that panel radiator power varies depending on type and dimensions. Each manufacturer creates the tables in which the test results are entered because it is impossible to calculate this parameter independently. Each room’s radiators are chosen for these tables.

Steel panel radiator types

Determine the power

The heat loss of the room where steel panel radiators will be installed must be taken into consideration when calculating the radiators’ power. You can start with the SNiP norms, which standardize the amount of heat needed for a 1 m 3 heated area, for apartments housed in typical houses:

  • Premises in brick buildings require 34W per 1m 3 .
  • For panel houses for 1m 3, 41W goes.

Calculate the amount of heat needed to heat each room based on these norms.

For instance, the ceiling height in a 3.2 m by 3.5 m panel house room is 3 m. Find the volume: 3.2 * 3.5 * 3 = 33.6 m. 3. 33.6*41 = 1377.6W is the result of multiplying by the NRP norm for panel houses.

The average climate zone’s SNiP norms are shown. There are suitable coefficients for the remaining ones based on the typical winter temperature:

It is evident that the more external walls there are, the more heat escapes, so we must address heat loss based on their number. As a result, we consider the following: a coefficient of 1.1 for a single wall, 1.2 for two, and 1.3 for three walls.

You must compute the room’s heat loss in order to accurately calculate the panel radiator’s power.

Let’s modify for the sake of our example. There are two external walls, and the average winter temperature is around -25 o C. As it happens, 1378W * 1.3 * 1.2 = 2149.68W, or 2150W rounded.

It is also necessary to consider the kind of material, roofs, and which rooms are above or below, among other things. See the article "How to calculate the number of radiator sections" to find out the coefficients for this.

And we’ll use this figure as an example. As long as the house and windows have average insulation, the figure discovered is fairly accurate.

Calculation of Kermi radiators

Prior to calculating power, you must select the steel panel battery brand. Leaders are, of course, trustworthy. German steel radiators Kermi are nearly unbeatable today. As a result, we compute the power using the manufacturer’s tables.

Let you decide to install one of the new Kermi Thermi X2 Plan models. According to the table in which the capacities of all existing models are indicated, we find suitable values. You should not look for an accurate coincidence, look for a value that is slightly more than calculated (in heat engineering it is better to have at least a small reserve “just in case”). In the table suitable for our case, options are marked with red squares. Let the height of 505mm (indicated at the top of the table) is more acceptable for us). More than others are attracted by less long (1005mm) panel radiators 33. If you need even shorter, you can pay attention to models with a height of 605mm.
