A note for buyers about Kermi Type 22 radiators, specifications, reviews, questions. Differences between Kermi FTV and Kermi FKV 22. Battery coating features. An example of calculating the center distance for Kermi radiators.
To create warmth and comfort in their home, many choose Kermi brand radiators. This is a German company that produces different models steel panel radiators for more than half a century. Despite their compactness, they have excellent heat transfer performance. And attractive appearance allows you to fit batteries into any modern interior.
The most popular model is Kermi 22 500 500 . The device consists of two steel panels, between them there are two convectors, which are made in the form of U-shaped fins. Distinctive feature- application in the manufacture of batteries of the unique Kermi Therm x2 technology. Due to the special design, the coolant first enters the front panel, so that the air in the room is heated first. The back panel heats up later and works like a screen.
By the way, before the introduction of the Therm x2 innovation, Kermi radiators with a bottom connection had the abbreviation FKV, but they have already been discontinued.
Specifications Kermi 22 type:
- The maximum coolant temperature is 110 degrees Celsius.
- Power depends on size. At temperature regime 90/70/20 and dimensions 500x500 power Kermi 22 radiatorsis 965 watts.
- Working pressure - 10 atmospheres.
- The maximum crimping pressure is 13 atmospheres.
- Thickness - 100 mm.
- Height - from 200 to 900 mm.
- Width - from 400 to 3,000 mm.
- Center distance - for FKO, 54 mm must be subtracted from the height, for example, for the Kermi 22 500 500 Radiator, this value will be 500 mm - 54 mm = 446 mm; for FTV, the distance between the tubes is 50 mm.
- Standard color is white Kermi RAL 9016
There are two versions depending on the type of connection.
1. RadiatorsKermi FKO 22. These are models with lateral connection, piping is carried out on the left or right.
2. Radiators Kermi FTV 22. Batteries with bottom connection. The advantage over FKO 22 is the ability to hide pipes in the floor or under the skirting board. Due to the increased complexity of manufacturing these devices, and also because of their high aesthetic qualities, the cost of Kermi FTV is higher.
Regardless of the type of connection, the steel Radiator Kermi Type 22 recommended for installation in heating systems closed type. In this case, the circulation can be natural or forced, the system is one- or two-pipe.
Upon purchase, the device package includes a plug, a Mayevsky valve - a valve for bleeding air, a set wall mounts. IN radiators Kermi 22 type with bottom connection built-in thermostatic valve, which allows you to install equipment to control the air temperature in the room.
Kermi panel radiators have an advantage over their counterparts - they are coated with iron phosphate and two layers of varnish. Such processing significantly increases the service life!
Externally, the radiator looks modern and stylish. It will not only heat your home, but also become stylish part interior. The ideally white surface is a lacquer coating that, when heated, does not release toxic substances into the air. On the sides, the radiator is closed with solid panels, and on top - with a grille.
Since ancient times, man has always striven to provide himself with the maximum comfortable conditions living, equipping your life. Actually, due to this kind of aspirations, conditions were created to help him progress. Things and household items that surrounded a person, those with which he cooked food, heated a dwelling, etc., underwent various kinds of changes.
Their shape and appearance changed, they became easier and more practical to use. There is only one goal - to create the most comfortable conditions for the life of 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 the fires began to be covered with stones, which greatly simplified the possibility of cooking food on them. Further - more: hearths are laid out of stones, chimneys are made. Here is practicality for you, here is convenience and comfort for you.
per century modern technologies When we mastered electricity, Kermi's steel radiators replaced the seemingly inconvenient and very bulky ones. And besides them, kermi steel panel 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 do these radiators have? 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. We would like to proudly announce that Germany is the manufacturer of kermi radiators. German quality, and there is nothing more to add.
Kermi radiators can be divided into several groups, of course conditionally:
— aluminum radiators;
— steel heating radiators Kermi;
— bimetallic radiators;
– heating radiators, on which the designer worked;
Kermi radiators, designed by the designer, will harmoniously blend into the interior of your country house or cottages, beautifully complementing it with their presence.
In addition to the above division, there is one more:
— monolithic radiators;
— sectional radiators;
The undoubted advantage of sectional radiators is their compactness, due to small size they can be placed even in the most unexpected places. Fitting into the interior for sectional-type batteries is not difficult.
But there are also disadvantages - rubber gaskets. When using, for example, antifreeze, the gasket quickly becomes unusable and needs to be replaced. Sectional type radiators include bimetallic and aluminum radiators.
There are also varieties of Kermi radiators, moreover, they already differ in types. So there are:
- type radiators Kermi fko - side connection radiators
- 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 connection
The choice of radiators today is very, very large. Even the most fastidious and captious buyer will be satisfied. But among this set, it is still possible to single out radiators that are most popular compared to other models.
I would like to bring to your attention Kermi steel radiators. These water radiators are used mainly in country houses or in dachas, this is due to the fact that they are not designed for great pressure. The thermal inertia of Kermi panel radiators is low, but the heat transfer, on the contrary.
If there is a device that, the reaction of the radiator 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 the question arises before you - which steel heating radiators are better, then 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 through the sleeves. Energy resources are now expensive, and therefore the heat that heating systems give us must be used rationally.
Here a few tips, which will help to realize all of the above:
- no matter what your Kermi water heating radiator is made of, it should be placed under the window. This is explained very simply: cold air currents coming from the windows will be blocked by warm streams released from the batteries.
- decorating radiators with panels will deprive the room of at least 15-20% of heat;
- place a couple of thin metal plates equipped with . The efficiency will increase significantly.
Treat yourself to comfort and convenience, conduct Kermi heating 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.
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 rather high cost compared to similar devices, are in constant demand, both for domestic market, and abroad.
About the brand
Kermi is a well-known manufacturer of steel radiators from Plattling, Germany. He has long established himself in this niche and still pays a lot of attention to the development and implementation of the latest technologies.
Although opinions are completely contradictory about most panel radiators, Kermi steel radiators are recognized as powerful and reliable.
This is due to the fact that their production is monitored at all stages:
- Selection of material for the manufacture of panels.
- Manufacturing control.
- Checking each product for durability.
Panel radiators Kermi (steel) are represented by a wide range of products of different colors, sizes and designs.
Kermi steel panel radiator
At the heart of any panel radiator are steel plates connected by a stock. They are made by stamping, in which inside panels are squeezed out special channels for the coolant. 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 effective work convectors are built into them, which are corrugated sheets of thin steel.
The whole structure is covered with side and top lids giving the product a neat and stylish look. The difference in the structure of Kermi radiators is the supply of the carrier, which does not fall simultaneously on all panels, 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 has proven itself even when operating in low temperature conditions. This has significantly expanded their scope, and Kermi panel heating radiators are perfectly combined with solar collectors and pumps of any capacity.
Another design feature of Kermi products are balanced control devices., which have been tested by the manufacturer for many years of testing. They allow you to create any comfortable conditions and at the same time save fuel consumption.
In the design of the products of this company, there are models with both side and bottom connections, and the latter can have wiring not only on the left and right, as is customary, but also in the middle.
The lineup
Although the company adheres to the parameters inherent in panel heaters, it has products with a smooth front surface, which are called Plan, and with a profile, slightly wavy - Profi.
If Kermi steel heating radiators are marked Plan (Fko), then these are products with a smooth panel and bottom connection, made in 3 versions: right, left and middle.
Plan FKV Models has a lateral connection and is represented not only by the main dimensions, but also by what is suitable for replacing old ones cast iron batteries. This saves time and money as you don't have to re-do the liner.
For medical institutions and allergy sufferers who are contraindicated in the accumulation of dust, suitable hygienic model Plan-V, in which a distance is observed that makes it easy to remove dust from the surface of the radiator.
All Kermi steel panel radiators are made in standard types 10, 11, 21, 22, 33, where the first number indicates the number of panels, and the second - about 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 what power he needs the device.
This does not bypass the Kermi steel heating radiators, specifications which have the following parameters:
- The main working pressure is 10 bar with a test pressure of 13 bar.
- Maximum allowable 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, the entire model range of this brand is divided into side and bottom connections, the latter being provided in valve devices that have the Latin letter V in the marking. 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 does not matter) is equipped by the manufacturer with a special separating plug, which must be correctly installed after the installation of the device. It is she who separates the coolant, ensuring the sequence of connecting the panels.
If the bottom connection is made according to the "Leningrad" principle, then the plug is not mounted, and the Therm-X2 effect will not work.
In the event that old heaters 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 need regular cleaning. As a rule, they are equipped with lids that tightly close the internal contents of the device. You can remove them using the "key", which is the company logo, made on a plastic plate. It needs to be pulled back slightly so as not to scratch the paint and rotated counterclockwise until it detaches. After removing it, you can remove the sides and cover and start cleaning the radiator.

IN Lately it became popular to change metal pipes for polypropylene. Panel piping steel radiator Kermy polypropylene is a good addition to a quality device.
These pipes are capable of withstanding pressures up to 25 bar and have long term operation up to 40 years. If you make the strapping by soldering using a special apparatus, then the service life of the radiators can be significantly increased.
Summing up, 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 the high price, which is fully compensated. long term battery operation.

Required thermal power Kermi radiators depend on:
- area of the premises;
- the volume of the room;
- room heat loss;
- characteristics of the heating system.
Determining the power of radiators based on the area
Building codes determine the average heat consumption per 1 m2 of the floor of the room - 100 W. This is a very approximate indicator, so they often resort to using the formula Q \u003d (2So + Sp + Sns) (0.54Dt + 22), where:
- Q is the desired total heat transfer of radiators;
- Dt is the difference between outdoor and indoor temperature;
- So is the window area;
- Sp - floor area;
- Sns is the area of "street" walls.
When choosing the Kermi model (radiators), the power is calculated according to this formula, but taking into account the heat losses inherent in a particular room. Experts can determine the exact indicators.
Determining the power of radiators based on the volume of the room
According to building codes, one cubic meter rooms require the following heat transfer:
- in panel buildings - 0.041 kW;
- in brick - 0.034 kW.
For example, let's take a room in a brick building. Ceiling height - 2.7 m. Walls 3 and 5 m long. Room volume - 40.5 m3. To obtain an 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 middle climatic zone and without taking into account the correction, which depends 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;
- 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 will be 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 obtained heat transfer by the required coefficients - 1377x1.2x1.5 = 2478.6 W. The rounded result is 2480 watts.
This number is relatively accurate, but the matter is not limited to the mentioned coefficients. Specialists in thermal calculations take into account what material the walls are made of, the characteristics of the rooms located around, etc. But, subject to average indicators, this number can be used. To determine the type of batteries, the Kermi radiator power table is used.
Choosing the type of Kermi radiator, taking into account the required power
The table shows the power various radiators brand. Red highlighted values suitable for our case. These batteries can be installed indoors with similar characteristics.
But for Kermi radiators, the power table only works if the average values \u200b\u200bof the temperature of the coolant and air in the room are observed:
- coolant t (supply) - 70 degrees;
- coolant t (return) - 65 degrees;
- t air - 20 degrees.
If the system characteristics differ from the average, it is required to multiply the received power by another factor. The latter can be determined using a table.
Kermi radiators are found in approximately 80-90% of stores selling heating equipment. It is easy to make sure of this - go to any store and check their availability, in the vast majority of cases the answer will be positive. Radiators from this German manufacturer are famous for their quality and endurance, and their variety allows you to heat rooms of any type. Therefore, we decided to dedicate a separate review to Kermi. In it we will tell:
- About the technologies used in production;
- On the technical characteristics of radiators;
- About the advantages and disadvantages of Kermi products;
- About the most demanded models.
Finally, we will publish user reviews.
Technical characteristics of Kermi radiators
Kermi heating radiators are manufactured in Germany. It immediately becomes clear that we are dealing with high-quality German products - they simply do not have anything else. Having started its activity in 1967, Kermi achieved brilliant results and became one of the leaders in the heating market. As of 2016, it produces the following lines of radiators:
- Profile;
- smooth;
- Radiators of the Line series.
Types and dimensions of panel radiators of the German manufacturer of heating appliances Kermi
Technical characteristics of Kermi radiators include the following parameters - height, length, depth, number of rows and number of rows of convective fins. The following types of radiators are on the market, indicated by numerical indices.
- Type 10 are single row devices without convective fins.
- Type 11 - single row radiators with one row of fins.
- Type 12 - two-row Kermi batteries with one row of fins.
- Type 22 - two-row radiators with two rows of fins.
- Type 33 - three-row batteries with three rows of fins.
The depth of the radiators varies depending on the type. For example, therm-x2 Profil-V single row models are 61 mm deep, double row 100 mm and triple row 155 mm. If you need low batteries, you should pay attention to profile models with a height of 200 mm. Also on sale are vertical radiator panels Verteo Profil, which have excellent appearance and quite high.
The list of important technical characteristics should include the type of connection. The V index is bottom-connected batteries, the K index is side-connected batteries.
Kermi profile heating radiators is a line that includes compact models with a height of 200 mm or more. These include the therm-x2 Profil-V, therm-x2 Profil-K and Verteo Profil product lines. The segment of smooth radiators includes the therm-x2 Plan-V, therm-x2 Plan-K, Verteo Plan, therm-x2 Plan-K replacement series (designed for quick and painless replacement of old batteries without altering the heating system) and therm- x2 Plan-V hygienic (for use in environments with strict hygiene requirements). All of these lines are characterized by a sleek design.
Radiators of Kermi of the Line series differ in attractive design. They are able to fit into any interior.
Kermi Line series batteries have an attractive front panel design – they are able to fit into any interiors. The series includes the therm-x2 Line-K, therm-x2 Line-V, therm-x2 Line-Hygiene, Verteo-Line and therm-x2 Line-K replacement lines (for the repair and modernization of old heating systems).
What does therm-x2 mean in the name of the rulers? This is an energy-saving technology used in the development of Kermi heating radiators. Thanks to this technology, the heating time is reduced and the efficiency of the heating system is increased. The water entering the batteries passes first through the front panel, and only then goes to the rear. This design provides a quick supply of heat to the premises. Today, therm-x2 technology is used in all Kermi batteries.
Advantages and disadvantages of Kermi batteries
German Kermi heating radiators have a lot of advantages and a minimum of disadvantages - this is typical for many types of goods made in Germany. Let's start with the key benefits:
Kermi Therm-x2 technology will save you money thanks to the special circulation of the coolant in the radiator.
- High efficiency due to the applied therm-x2 technology - provides a reduction in heating costs;
- High-quality steel base - ensures a long service life;
- Pressure resistance up to 10 atmospheres - test pressure for many models is 13-14 atmospheres;
- An abundance of models - for any interiors;
- The presence of built-in thermostats (typical for some models);
- Rapid heating of rooms - provided by therm-x2 technology.
As for the shortcomings, there are very few of them:
- Lack of water hammer resistance- steel does not withstand strong overloads;
- Somewhat high prices - you have to pay for the quality of German products.
Thus, Kermi heating batteries will become great solution for residential heating.
