Since ancient times, man has always strived to provide himself with the maximum comfortable conditions living, arranging your life. Actually, due to this kind of aspirations, conditions were created that helped him progress. Things and household items that surrounded a person, those with the help of which he prepared food, heated his home, etc., were subject to various kinds of changes.
Their shape and appearance changed, they became simpler and more practical to use. There is only one goal - to create the most comfortable living conditions for the one who invented and improved these things. Let's take home heating as an example. This is a mandatory measure necessary for survival.
It all started with ordinary fires in caves, which were “fed” with firewood. Then they began to cover the fires with stones, which greatly simplified the possibility of cooking food on them. Further - more: hearths are laid out from stones, chimneys are made. Here's practicality, here's convenience and comfort.
In the century modern technologies, when we mastered electricity, they replaced what already seemed inconvenient and very cumbersome steel radiators Kermi. And in addition to them, kermi panel steel radiators, characterized by compactness and high performance.
Kermi radiators: table of types and distinctive technical characteristics
So, what are Kermi steel heating radiators and which ones are better? What modifications are there for these radiators? How difficult is the installation of each of the presented models, and how is it carried out? Read about all this below, the details are there.
At the very beginning I would like to say that the Germans and quality are two interrelated things. I would like to proudly announce that kermi radiators are manufactured in Germany. German quality, and there is nothing more to add here.
Kermi radiators can be divided into several groups, of course conditionally:
— radiators made of aluminum;
— steel heating radiators Kermi;
— bimetallic radiators;
— heating radiators, which the designer worked on;
Kermi radiators, designed by the designer, will harmoniously fit into the interior of your country house or dacha, beautifully complementing it with your presence.
In addition to the above division, there is one more:
— monolithic radiators;
— sectional radiators;
A definite plus sectional radiators is their compactness; due to their small size, they can be placed even in the most unexpected places. It doesn’t seem difficult for sectional type batteries to fit into the interior.
But there are also disadvantages - rubber gaskets. When using, for example, antifreeze, the gasket quickly becomes unusable and needs to be replaced. Sectional radiators include bimetallic and aluminum radiators.
There are also varieties of Kermi radiators, and they differ by type. So there are:
- type radiators Kermi fko – radiators with side connection
- type radiators Kermi fkv – with bottom connection.
A very convenient solution, thanks to which you can install it anywhere you want.
Kermi steel radiators with side and bottom connections
The choice of radiators today is very, very large. Even the most fastidious and picky customer will be satisfied. But among this set, it is still possible to identify radiators that are the most popular compared to other models.
I would like to present to your attention Kermi steel heating radiators. These water radiators are used mainly in country houses or at dachas, this is due to the fact that they are not designed for high pressure. Thermal inertia panel radiators Kermi is low, but heat transfer is the opposite.
If there is a device that, the radiator’s response to its command will be immediate and prompt. The popularity of steel panel radiators is also explained by the fact that in their case there is an ideal price-quality ratio. If you have a question about what are the best steel heating radiators, then by choosing a German manufacturer, you will not be disappointed.

How to connect Kermi heating radiators
Installation of heating radiators is very important point, which should not be approached carelessly. Energy resources are now expensive, and therefore the heat that heating systems provide us must be used rationally.
Here some tips, which will help bring all of the above to life:
- no matter what your Kermi water heating radiator is made of, it should be located under the window. This can be explained very simply: cold air currents coming from the windows will be blocked by warm air currents released from the radiators.
- decorating radiators with panels will deprive the room of at least 15-20% of heat;
— place behind the radiator a couple of thin metal plates equipped with. Efficiency will increase significantly.
Give yourself comfort and convenience by heating Kermi by purchasing a sectional or monolithic water-type radiator with optimal technical characteristics. A huge selection of Kermi radiators, as well as everything for Kermi, is presented in online stores.
Among the brands producing steel heating devices, the undisputed leader is German brand Kermi. The products of this company are distinguished by high quality, reliability and the introduction of modern technologies aimed at maximizing energy consumption reduction. In this article we will review the types and technical characteristics that distinguish Kermi steel radiators.
Innovative Kermi radiator design
If the story about radiators is replete with cliches like: “made from sheet steel highest quality using the latest technology”, or “durable powder coating in any color”, then you will quickly get bored.
You say - this is written on the website of any battery manufacturer, everyone praises their products. And you’ll be right, they write everything well, but how everything is actually done is a question. Therefore, let’s move straight to the specific feature that distinguishes Kermi panel radiators from all others.
It would seem, what other solutions can be implemented in heating devices, when everything that is possible has already been invented? It turns out not all. The Germans added internal piping to the radiators. This allows you to heat only the front panel of the device in normal mode; no water circulation occurs in the rear part. But as soon as the room temperature drops, the built-in thermostat will open the way for coolant to the rear panel, leading the radiator to full power. Otherwise, these are ordinary steel batteries, only very reliable and made in compliance with the highest requirements to quality.
Note. In connection with the implementation new technology Alternating supply of coolant to the front and rear parts, the Kermi radiator received the prefix “therm X2” in its designation.
Types and characteristics of Kermi heating devices
At the moment, the brand offers the following types of traditional steel batteries:
- profile therm X2 profil K (compact) and Profil V (valve);
- smooth therm X2Plan K (compact), Plan V (valve), Verteo Plan (vertical);
- with horizontal profiling of the front panel therm X2 line K (compact), Line V (valve), Verteo Line (vertical).
As for the types of radiators offered, all standard types are produced under the Kermi brand, from 10th to 33rd. Let us recall that the first number in the designation indicates the number of heating panels, and the second – the number of convective fins. The most popular is type 22, where 2 panels and the same number of fins are used, as shown in the figure:
Are common specifications Kermi radiators are presented in the table below:
The listed 3 types of batteries differ in appearance by the type of profiling or lack thereof. While their heat transfer rates are somewhat different. It should be noted that the power of Kermi radiators is declared by the manufacturer in relation to the installation length. Therefore, first we present a table of the thermal power of 1 m of profiled devices (therm X2Profil) depending on the height, type and operating temperature curve of the coolant:
Note. Since Kermi therm X2 Verteo vertical steel batteries are used much less frequently than traditional ones, we will not present their characteristics here. The corresponding tables can be studied on the manufacturer’s Internet resource.
Connection diagrams
All three types of products provide side and bottom connections for Kermi radiators, and the pipes for connection from below can be located in three options to choose from: right, left and middle. Bottom method connection is provided in all valve devices (at the end of the designation there is a Latin V), and side connection is provided in compact ones (the letter K in the designation). Internal wiring clearly visible on batteries with bottom connection:
For reliable operation of its products and the full functioning of the X2 series connection effect, the manufacturer requires connection to be made in accordance with certain requirements.
A diagram of how radiators with side connections should and should not be connected is presented below:
Advice. After purchasing and installing the Kermi battery in its place, carefully read the instructions that came with it. It describes in detail how to correctly install the separating plug in the return line of the device when it will operate in one - or two-pipe system heating. This plug provides the X2 function (sequential switching of panels), so there is no mistake here.
It is also possible to connect a radiator from different sides from below, as is customary to do in the popular one-pipe heating system “Leningradka”. But in this case, the separation plug is not installed, the X2 effect does not work, and the heat transfer value of the battery is reduced by 8%.
Valve heating devices, in which the connecting pipes are located at the bottom, are not allowed to be connected from the side on any side, but only as required by the manufacturer. The following figure shows the installation diagram of a radiator with a bottom connection:
In a situation where, when replacing old heating devices with new ones, the center distances of Kermi batteries may differ from the previous ones, the situation can be corrected using special adapters. Their installation allows you to adjust the distance between pipelines without dismantling or altering them.
Conclusion
Kermi radiators are a high-quality product manufactured using high technology, and therefore a priori cannot be cheap. This is the only drawback of these devices that you will have to come to terms with if you want to have warmth and comfort in your home for many years.

The required thermal output of Kermi radiators depends on:
- room area;
- room volume;
- heat loss of the room;
- characteristics of the heating system.
Determining the power of radiators based on area
Building codes define average consumption heat per 1 m2 of room floor – 100 W. This is a very approximate indicator, so they often resort to using the formula Q= (2So+Sp+Sns)(0.54Dt+22), where:
- Q – the required total heat transfer from radiators;
- Dt – difference between outside and inside temperatures;
- So – window area;
- Sp – floor area;
- Sns – area of “street” walls.
When choosing a Kermi model (radiators), the power is calculated using this formula, but taking into account the heat loss characteristic of a particular room. Experts can determine the exact indicators.
Determining the power of radiators based on the volume of the room
According to building regulations, one cubic meter the room requires the following heat transfer:
- V panel buildings– 0.041 kW;
- in brick - 0.034 kW.
For example, let's take a room in brick building. Ceiling height – 2.7 m. Walls 3 and 5 m long. Room volume – 40.5 m3. To obtain the average power indicator, it is necessary to multiply the volume by a factor of 0.034 kW. The result of the product (40.5x0.034) is 1.377 kW (1377 W).
But this result is valid only for the average climate zone and without taking into account the correction depending on the number of external walls and windows. The illustration shows the dependence of the coefficients on the average winter temperature.
Some coefficients by which you need to multiply the average required heat transfer, depending on the number of external walls and windows, as well as taking into account the location of window openings:
- 1 outer wall – 1,1;
- 2 external walls and 1 window – 1.2;
- 2 external walls and 2 windows – 1.3;
- the windows “look” towards the north – 1.1.
If radiators are supposed to be installed in a niche, then for Kermi batteries the power calculation is adjusted taking into account a factor of 0.5. If the thermal structure is covered with a perforated panel, the average value should be multiplied by 1.15.
For example, in our conditional room with a volume of 40.5 there are two walls facing the street. At the same time, the average temperature in winter is -30. In this case, we multiply the resulting heat transfer by the required coefficients - 1377x1.2x1.5 = 2478.6 W. The rounded result is 2480 W.
This number is relatively accurate, but the matter is not limited to the mentioned coefficients. When making thermal calculations, specialists take into account what material the walls are made of, the characteristics of the surrounding rooms, etc. But, provided that the average indicators are averaged, this number can be used. To determine the type of batteries, the power table of Kermi radiators is used.
Selecting the type of Kermi radiator taking into account the required power
The table shows the power of various brand radiators. The values that apply to our case are highlighted in red. These batteries can be installed in a room with similar characteristics.
But for Kermi radiators, the power table only works if the average temperatures of the coolant and air in the room are observed:
- t coolant (supply) – 70 degrees;
- t coolant (return) – 65 degrees;
- t air - 20 degrees.
If the system characteristics differ from the average, the resulting power must be multiplied by another factor. The latter can be determined using a table.
Reliability - this is the quality that interests consumers when choosing heating radiators for a house or apartment.
German-made Kermi steel panel radiators are associated precisely with this concept, and, despite the fairly high cost compared to similar devices, they are in constant demand both in the domestic market and abroad.
About the brand
Kermi is a well-known manufacturer of steel radiators from the German city of Plattling. He has long established himself in this niche and continues to pay much attention to the development and implementation of the latest technologies.
Although there are completely contradictory opinions about most panel radiators, Kermi steel radiators are recognized as powerful and reliable.
This is because their production is monitored at all stages:
- Selection of material for the manufacture of panels.
- Manufacturing control.
- Checking each product for strength.
Kermi panel radiators (steel) are presented in a wide range model range products different color, size and design.
Steel panel radiator Kermi
At the heart of any panel radiator are steel plates connected by a rootstock. They are made using the stamping method, in which inside The panels have special channels for the coolant pressed out. Two of them are horizontal and located at the top and bottom of the steel stamping, and the rest are vertical.
Steel panels connected in pairs subsequently become the base of the batteries. Depending on the required level of heat transfer from the device, Kermi steel heating radiators consist of one, two or three rows of panels.
For more efficient work Convectors, which are corrugated sheets of thin steel, are built into them.
The entire structure is covered with side and top covers, giving the product a neat and stylish look. The difference in the structure of Kermi radiators is the supply of media, which does not reach all panels simultaneously, as in similar products from other manufacturers, but sequentially.
This means that the front panel heats up first, while the second and third (depending on the model) have a lower temperature. This allows you to maximize the efficiency of the radiator, heating the room 25% faster, and the heat is not wasted on heating the wall.
This technology is labeled Therm-X2, and it has proven itself even when operating in low-temperature conditions. This has significantly expanded their scope of application, and Kermi panel heating radiators are perfectly combined with solar collectors and pumps of any power.
Another design feature of Kermi products is balanced control devices, which have been tested by the manufacturer over many years of testing. They allow you to create any comfortable conditions and at the same time save fuel consumption.
The design of this company’s products includes models with both side and bottom connections, and in the latter, the wiring can be located not only on the left and right, as is usually the case, but also in the middle.
The lineup
Although the company adheres to the parameters characteristic of panel heating devices, it has products with a smooth front surface, called Plan, and with a profile, slightly wavy surface - Profi.
If Kermi steel heating radiators are marked Plan (Fko), then these are products with a smooth panel and a bottom connection made in 3 options: right, left and middle.
Models Plan FKV It has side connection and are presented not only in basic sizes, but also in those that are suitable for replacing old ones cast iron batteries. This will save time and money, since you won't have to redo the eyeliner.
Suitable for medical institutions and allergy sufferers, for whom dust accumulation is contraindicated. hygienic model Plan-V, in which a distance is maintained that allows you to easily remove dust from the surface of the radiator.
All Kermi steel panel heating radiators are made in standard types 10, 11, 21, 22, 33, where the first number indicates the number of panels, and the second – the convectors.
Read about the technical characteristics of Kermi steel radiators below.
Specifications
The technical passport for the product is the main document by which the consumer determines how much power he needs the device.
This does not bypass Kermi steel heating radiators, the technical characteristics of which have the following parameters:
- Basics operating pressure 10 Bar at test 13 Bar.
- Maximum permissible temperature water in the system is +110 degrees, and the working one is +95.
- The height of the products varies from 300 mm to 900 mm.
- Length – from 400 to 3000 mm.
- The depth of the product depends on its type. So for models 10 and 11 it is 61 mm, for 12 - 64 mm, for 22 - 100 mm, and for type 33 - 155 mm.
According to the connection method, all the lineup this brand is divided into side and bottom eyeliner, and the latter is provided in valve devices that are marked with the Latin letter V. The side connection, which is used in compact devices, has the letter K in the marking.
Features of installation and care
Each Kermi steel radiator (Fko or FKV, it doesn’t matter) is equipped by the manufacturer with a special separation plug, which must be installed correctly after installing the device. It is this that separates the coolant, ensuring the sequence of connecting the panels.
If the bottom connection is made according to the “Leningradka” principle, then the plug is not mounted, and the Therm-X2 effect will not work.
In the event that old heating devices are replaced with Kermi steel radiators, special adapters will be required that adjust the distance between the pipes.
Like other types of heating devices, Kermi brand radiators require regular cleaning. As a rule, they are equipped with lids that tightly cover the internal contents of the device. They can be removed using a “key”, which is the company logo made on a plastic plate. You need to pull it slightly so as not to scratch the paint and turn it counterclockwise until it comes off. After removing it, you can remove the sides and cover and start cleaning the radiator.

Recently, it has become popular to replace metal pipes with polypropylene ones. Tying a Kermi panel steel radiator with polypropylene is a good addition to a quality device.
These pipes can withstand pressures up to 25 Bar and have long term operation up to 40 years. If the piping is carried out using the soldering method using a special apparatus, the service life of the radiators can significantly increase.
To summarize, we can say that Kermi steel panel radiators are one of the highest quality, reliable and powerful heating devices made of this material on the domestic market. Their only drawback is high price, which is fully compensated by the long battery life.
Technical characteristics and connection
Radiators of the German brand Kermi (Kermi) have become one of the most popular on Russian market positions; Today many of our compatriots readily use them to heat their homes.
Kermi have truly become a recognized leader in their segment. Their steel panel radiators (and not only) have become widely known in the world, and popularity, as you know, is the second component of success. And quality. Today the company produces not only its traditional steel batteries, but also bimetallic ones. They have two types of connection - bottom and side. And three different thicknesses of metal.
Steel radiators are more suitable for country houses, in which the pressure is not as high as in the city. Steel radiators are at risk of water hammer; bimetallic batteries are capable of maintaining pressure up to 30 atmospheres.
In order not to waste your time by describing their external advantages, I suggest you look below short video about these devices, so you can form your own idea about them.
Consumers have an interest in different models, including decorative batteries with an unusual stylish design
The heating equipment of the Kermi series of radiators is mainly intended for individual houses and cottages, and have the appropriate appearance: refined, elegant, noble. This is not to say that they are cheap, but they say that the costs are justified high degree comfort.
In fact, the operation of any liquid radiator is based on one principle - coolant (in in this case This is water) enters the radiator tank and slows down, gradually cooling down and transferring heat into the room.
The main advantage of these devices is their high specific thermal power. So Kermi radiators are considered very powerful.
Batteries transfer heat by thermal radiation from the front surface and have very decent heat transfer. They are usually installed in autonomous systems heating, since they are designed for low operating pressure.
It’s hard to disagree with the fact that the appearance of Kermi brand radiators is quite aesthetic. Batteries have various sizes. Radiators are mainly produced white, they are covered with a special powder coating (according to the manufacturer, it is environmentally friendly! I have not yet seen any refutations, so it is quite possible that this is true), which seems to allow the temperature to be maintained longer. But there are decorative models that differ from the main line in both color and design.
About the manufacturer
German company Kermi founded back in 1960. Since 1967, the company has been closely involved in the production of steel panel radiators. (By the way, since 1976 it has also been closely involved in the production of shower cabins). And by 1975 Kermi has achieved a leading position in this segment. Of course, most of all Kermi known in Germany itself, but they are also well known in other European countries.
On the Russian market these heating batteries They showed themselves relatively recently, but they are trusted. And the 5-year warranty from the manufacturer is certainly captivating.
Characteristics
Each of the Kermi brand's snow-white products launched on the market is equipped with a side panel and a top grille. Each battery is tested at the factory at a pressure of 10-13 bar before entering the market.
Complete with the device itself, the manufacturer also supplies special air vent plugs and brackets.
The number of radiator panels is indicated on the marking:
- type 10 - one panel;
- type 11 - panel with fins;
- type 21 - a pair of panels and one fin;
- type 22 - a pair of panels and a pair of fins;
- type 33 - three panels and three rows of fins.
Thanks to the enviable variety of radiator sizes, they can be selected to suit any room and any location.
If a massive radiator with dimensions of 300 x 2000 mm requires a fairly spacious room, and sometimes it is possible to assemble it almost on the street under a window, then compact models of Kermi radiators (for example, 45 mm in depth) are not at all difficult to install at home.
Steel panel heating radiators of the Kermi brand are impeccable quality devices with high heat output and stylish design.
- Height in the range of 300-900 mm;
- Length in the range of 400-3000 mm;
- Kermi radiators are produced as single-layer, double-layer and three-layer.
Kermi steel panel radiators are designed as a pair of panels connected metal pipes where the heated coolant flows. The design of conventional radiators involves the circulation of coolant simultaneously through two panels, in this case the result is uniform heating of the radiator surface. Not so long ago, such a method of heating the coolant was considered the most rational.
But Kermi steel radiators, manufactured using special Therm X2 technology, are made differently. The coolant in radiators first passes through the front panel, and after that it is supplied through pipes to the rear panel.
Such coolant circulation contributes to faster heating of the front panel, which increases the power of the actual thermal radiation. A slightly cooled coolant circulates in the rear radiator panel, causing the panel to warm up a little longer.
Should I count? this nuance design flaw? Perhaps even the opposite. The fact is that the rear panel of the radiator plays a role in this case good screen, thanks to which unnecessary heat losses and there is almost no wasted energy wasted on heating the wall.
Power
When talking about the advantages of Kermi, it is considered necessary to remember such innovative technology, which is patented by a company like ThermX2. It is precisely due to the fact that the coolant in the battery first warms up outer panel, facing the room, and only after that it enters the rear panel, the device provides thermal energy savings of up to 11%.
Kermi Profil - Kompakt FKO panel radiators have a side or bottom connection. Kermi FKO devices, having a side connection, are intended for heating rooms as in standard heating systems with coolant temperatures up to 110 degrees. C, and in systems with lower temperature indicators.
Kermi batteries can be connected to the system from either side (right or left). Kermi devices function well in heating systems based on forced circulation coolant.
Radiators Kermi Profil - Ventil FKV, with a basic bottom connection, are designed to work in the most different systems heating at any coolant temperature. Special thermostatic valves are installed in Kermi radiators.
Nothing prevents radiators from working in heating systems with any type of coolant circulation.
