Review of Kermi heating radiators. Kermi radiators - heating devices of German quality Thermal power of kermi radiators

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. They have two types of connection - bottom and side. And three different thicknesses 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 to 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 by the high degree of comfort.

In fact, the operation of any liquid radiator is based on one principle - the coolant (in this case it 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 come in different 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 plugs for air release and attaches 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.

Panel steel radiators Kermi by design is 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 this nuance be considered a 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 merits of Kermi, it is considered necessary to remember this innovative technology, which is patented by the company as 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 with 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.

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 determine the average heat consumption per 1 m2 of floor space - 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 of room requires the following heat transfer:

  • in 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 heating structure is closed 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. Wherein average temperature in winter – -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.

Kermi radiators are found in approximately 80-90% of stores selling heating equipment. It’s easy to verify 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 durability, and their diversity allows you to heat any type of room. Therefore, we decided to devote a separate review to Kermi. In it we will tell you:

  • About the technologies used in production;
  • About the technical characteristics of radiators;
  • About the advantages and disadvantages of Kermi products;
  • About the most popular 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 activities in 1967, Kermi has achieved excellent results and has become one of the leaders in the heating market. As of 2016, it produces the following lines of radiators:

  • Profile;
  • Smooth;
  • Line series radiators.

Types and sizes of panel radiators from the German heating appliance manufacturer Kermi

Technical characteristics of Kermi radiators include following parameters– height, length, depth, number of rows and number of rows of convective fins. The following types of radiators are available on the market, designated by numerical indices.

  • Type 10 are single-row devices without convective fins.
  • Type 11 – single-row radiators with one row of fins.
  • Type 12 - double-row Kermi batteries with one row of fins.
  • Type 22 – double-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, single-row therm-x2 Profil-V models have a depth of 61 mm, double-row 100 mm, and three-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 an excellent appearance and are quite tall.

The list of important technical characteristics should include the type of connection. Index V refers to batteries with a bottom connection, index K refers to batteries with a side connection.

Kermi profile heating radiators are a line that includes compact models with a height of 200 mm. These include the therm-x2 Profil-V, therm-x2 Profil-K and Verteo Profil model series. The segment of smooth radiators includes the model ranges therm-x2 Plan-V, therm-x2 Plan-K, Verteo Plan, therm-x2 Plan-K for replacement (designed for quick and painless replacement of old batteries without reworking the heating system) and therm- x2 Plan-V hygienic (for use in areas subject to harsh hygienic requirements). All of these lines feature a sleek design.

Kermi Line series radiators are different attractive design. They can fit into any interior.

Kermi Line Series batteries have an attractive front panel design - they can fit into any interior. The series includes therm-x2 Line-K, therm-x2 Line-V, therm-x2 Line-Hygiene, Verteo-Line and therm-x2 Line-K replacement lines (for repairs and modernization of old heating systems).

What does therm-x2 mean in the names of the lines? This is an energy-saving technology used in the development of Kermi heating radiators. Thanks to this technology, 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 ensures rapid 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 products made in Germany. First, let's describe the key advantages:

Kermi Therm-x2 technology will help save your money thanks to the special circulation of coolant in the radiator.

  • High efficiency due to the therm-x2 technology used – ensures reduced heating costs;
  • High-quality steel base – ensures long service life;
  • Resistance to pressure up to 10 atmospheres - test pressure for many models is 13-14 atmospheres;
  • An abundance of models - for any interior;
  • Availability of built-in thermostats (typical for some models);
  • Fast heating of rooms is ensured by therm-x2 technology.

As for the disadvantages, there are very few of them:

  • Lack of resistance to water hammer– 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 heating residential premises.

Reviews of Kermi batteries

Most reviews about Kermi heating batteries are positive. And this was to be expected - it affects high quality assembly and use of high-quality raw materials. Adding here the German desire to do the right and durable things, we get excellent radiators for private houses and apartments. Read reviews of Kermi products in our review.

My apartment has been in need of renovation for a long time. Therefore, upon retirement, I immediately tore down the floors, tore off the wallpaper, threw old furniture and chandeliers. Since such a dance began, I decided to change the batteries. I had not heard anything about modern batteries, so I succumbed to the persuasion of the sellers - they recommended German-made Kermi radiators. I readily believe the Fritz, they know how to make things of high quality and durability. So I didn’t have to think long; I chose Kermi. For 3 years now they have been pleasing my wife and me with their warmth and good appearance. There were no leaks, so we and our neighbors sleep peacefully.

Since ancient times, man has always strived to provide himself with the most comfortable living conditions by arranging his 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 easier 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, Kermi steel radiators replaced what already seemed inconvenient and very bulky. 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 the manufacturer of kermi radiators is 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 small sizes 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.

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. The thermal inertia of Kermi panel radiators 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 they give us heating systems, 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 a couple of thin ones behind the radiator metal plates, equipped . 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.

The Kermi trademark belongs to the German holding AFG Arbonia-Forster-Holding AG. Steel panel radiators are produced under this brand. At a considerable price, the demand for them is stable - the quality is high, specifications allow use not only in individual heating systems, but also in centralized heating systems (with some restrictions).

Design Features

Any panel radiator consists of steel plates connected in pairs. The plates are stamped with channels through which the coolant moves. There are two horizontal channels - one at the top, the other at the bottom, and a large number of vertical ones. The plates connected in pairs are assembled into radiators one, two or three pieces at a time. To increase heat transfer, convective fins can be welded to them - corrugated steel sheets small thickness. They are located behind the front panel and do not spoil the appearance, but are covered with lids on the sides and top.

Kermi batteries are made the same way. The order in which the coolant is supplied differs. It's parallel for everyone. This means that the liquid at the same temperature is supplied to all panels in the radiator. This delivery method works very well when high temperature online. But as soon as the temperature decreases (warming, for example), the radiators become almost cold.

In Kermi panel radiators, the coolant supply is sequential and this technology is called Therm-X2. This means that the hottest flow is supplied to the first panel, and then to the second and third. Thus, the heated part is the part that faces the room. And the second and third are increasingly colder. In this case, most of the heat goes into the room, and non-production costs for heating the wall behind the radiator become much lower. Therefore, at the same coolant temperature and the same size, Kermi batteries heat the room 25% faster.

The new Therm-X2 technology makes it possible to warm up the room well even in low-temperature operating modes. This feature makes it possible to use Kermi flat panel radiators not only with traditional heat sources. They work very effectively with low-potential sources: from any type, .

Another new feature has been used in these radiators. The company establishes balanced . Balancing parameters were determined as a result of research. All bottom-connected steel radiators are supplied from the factory with balanced and adjusted thermostats (the thermal head must be purchased separately). By installing such a heating device, you get a stable temperature in the room: the amount of coolant required to maintain the temperature is supplied to the collector. You need to change the setting if you are not satisfied with the selected mode. Using a thermostat is not only comfort; for individual systems it is also an opportunity to save money: it is only spent on heating required quantity fuel.

There are some other features in connecting Kermi radiators. There are options for side and bottom pipe supply. Moreover, the bottom one can be not only right or left, but can also be located in the center. This allows you to make the wiring without being tied to the presence of heating devices. They can generally be installed after completion finishing works(you just need to first secure the brackets to the wall).

Models of Kermi panel radiators

There are two main types: smooth and profile. The smooth ones have an absolutely flat front panel - they are called Plan, the profile ones are called Profil - and have the usual slightly corrugated surface.

In the group of smooth radiators there are Plan-V models, which are labeled as FKO. These are the same “Kermi” radiators with a bottom connection, and in three options: left, right, or in the center.

Plan-K models are a side connection option (marked FKV). This group has an option for replacing old ones cast iron radiators- with center distances of 500 mm and 900 mm. In this case, there will be no need to digest the liner (if the pipes are in good condition).

FKO and FKV radiators are available in types 10, 11, 21, 22, 33. The first number is the number of panels through which the coolant flows, the second is the number of additional convective plates.

In the group of smooth panel batteries there is Plan-V hygienic - without additional fins and covers. Such models are required for medical institutions or for those who suffer from allergies. A large number of ribs contribute to the accumulation of dust, and small distances between the plates complicate cleaning. Hygienic option devoid of this disadvantage.

There is an unusual Kermi Verteo Plan. This is a vertical smooth panel radiator. It is useful in cases where it is not possible to find a place to install a wide radiator. But you need to keep in mind that its operating pressure is lower than all other models - 6 bar.

Kermi profile radiators are available in two modifications - Profil -V and Profil -K - lines with bottom (V) and side (K) connections. There is also a modification of vertical radiators Verteo Profil. The types of these panel batteries are the same, the depth is slightly smaller (2-3 mm).

Radiators "Kermi": characteristics

Smooth and profile models with side and bottom connections have the following technical characteristics:

  • Working pressure up to 10 Bar;
  • Test up to 13 Bar;
  • Maximum coolant temperature +110 o C;
  • Inlet pipes G 3/4” or G 1/2”;
  • Height from 300 mm to 900 mm;
  • Length from 400 mm to 3000 mm.
  • Thermal power depends on type, height and length.

The video describes in detail the types of Kermi batteries, the connection methods - side and bottom, how to connect different types pipes and what is needed for this.

Features of operation

Any radiators require cleaning from dust two to three times a season: dust greatly reduces heat transfer. Moreover, in the streams warm air it rises to the top and can cause allergy attacks. But some models (except type 10 and hygienic) panel radiators are closed on all sides: there are side covers and a grille at the top. There are no latches or other devices visible from the outside.

There is only a plastic “Kermi” logo on the side panel. So he serves as the key. Pull the left edge of the logo towards you and turn it down a little. A hole opens. But the logo still needs to be turned counterclockwise until it comes off (it screws onto a plastic threaded pin, so don’t pull too hard). But the left edge needs to be pulled back all the time - there is a locking edge there that can scratch the paint. After you remove the logo, you can pull the side plate down so that it is removed from the latches. If the model has a valve, remove the left panel first; there is a valve on the right and is in the way. After removing the sides, nothing holds the lid. Can be cleaned.

Assembly proceeds in the reverse order: install the top grille, then the side panels (first right, then left), and then the logos.
