Radiators "Kermi" - excellent quality and performance. Kermi Radiators: Overview, Specifications Kermi Radiator Specifications Dimensions

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 to use not only in systems of individual, but also centralized heating (with some restrictions).

Design features

Any panel radiator consists of steel plates connected in pairs. In the plates, the channels through which the coolant moves are squeezed out by stamping. There are two horizontal channels - one above, one below, and a large number of vertical ones. Plates connected in pairs are assembled into radiators one, two or three pieces each. To increase heat transfer, convective fins can be welded to them - corrugated steel sheets of small thickness. They are located behind the front panel and do not spoil appearance, and covered with lids on the side and top.

Kermi batteries are made in exactly the same way. They differ in the order of supply of the coolant. All of them are parallel. This means that liquid of the same temperature is supplied to all panels in the radiator. This method of feeding works very well at high temperatures in the network. 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 stream is fed to the first panel, and then to the second and third. Thus, the part that faces the room turns out to be the most heated. And the second and third are all 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 less. 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 heat the room well even in low temperature regime work. 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, .

One more novelty is applied in these radiators. The firm establishes balanced Balancing parameters were determined as a result of research. Everything steel radiators with bottom connection from the factory are supplied with balanced and adjusted thermostats (thermal head must be purchased separately). By installing such a heater, you get a stable temperature in the room: the amount of coolant that is required to maintain the temperature is supplied to the collector. You need to change the setting if you are not satisfied with the set mode. Using a thermostat is not only comfort, for individual systems it is also an opportunity to save money: only the right amount of fuel is spent on heating.

There are some more features in connecting Kermi radiators. Side and bottom piping options are available. Moreover, the bottom can be not only right or left, but can also be located in the center. This allows you to make wiring without being tied to the presence heating appliances, They can generally be installed after the end finishing works(only you will need to pre-fix the brackets on the wall).

Models of Kermi panel radiators

There are two main types: smooth and profiled. Smooth ones have an absolutely flat front panel - they are called Plan, 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 marked as FKO. These are the same Kermi radiators with a bottom connection, and in three versions: left, right, or in the center.

The Plan-K models are the side connection option (FKV marking). This group has an option for replacing old cast iron radiators- with center distance of 500 mm and 900 mm. In this case, it will not be necessary to digest the eyeliner (if the pipes are in good condition).

FKO and FKV radiators are available in types 10, 11, 21, 22, 33. The first digit 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 ribs 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. The hygienic version is devoid of this drawback.

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

Kermi profile radiators are available in two versions - Profil -V and Profil -K - lines with a lower (V) and side (K) connection. There is also a modification of vertical radiators Verteo Profil. The types of these panel batteries are the same, slightly less deep (by 2-3 mm).

Radiators "Kermi": characteristics

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

Operating 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.
The heat output depends on the type, height and length.

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

Operation features

Any radiators require cleaning from dust two or three times a season: dust greatly reduces heat transfer. In addition, in the currents of 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 grill at the top. From the outside, no latches or other fixtures are visible.

There is only a plastic Kermi logo on the side panel. Here he is the key. Pull the left edge of the logo towards you, turn it down a little. A hole opens. But the logo still needs to be turned counter-clockwise until it unscrews (it screws onto a threaded plastic pin, so don't pull too hard). But the left edge needs to be pulled back all the time - there is an influx-lock that can scratch the paint. After you remove the logo, you can pull the side plate down to release it from the latches. If there is a valve in the model, first remove the left panel, there is a valve on the right and interferes. After removing the sides, the lid does not hold anything. Can be cleaned.

The assembly is in the reverse order: install the upper grille, then the sidewalls (first the right, then the left), and then the logos.

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 an excellent appearance and a fairly large height.

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 lineups therm-x2 Profil-V, therm-x2 Profil-K and Verteo Profil. 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 be an excellent solution for heating residential premises.

Kermi battery reviews

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

My apartment is in need of renovation. Therefore, when I retired, I immediately ripped off the floors, tore off the wallpaper, threw old furniture and chandeliers. Since such a dance has gone, I decided to change the batteries. I didn’t hear anything about modern batteries, so I succumbed to the persuasion of the sellers - they advised German-made Kermi radiators. I readily believe the Fritz, they know how to make things of high quality and durable. Therefore, I didn’t have to think long, I chose Kermi. For 3 years now they have been pleasing me and my wife with warmth and good appearance. There were no leaks, so we and our neighbors sleep peacefully.

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 has been producing various models of 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. With a temperature regime of 90/70/20 and dimensions of 500x500, the 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 of wall mounts. V 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 warm your home, but also become a stylish part of the 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.

The required heat output of Kermi radiators depends 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 of various brand radiators. 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.

Specifications and connection

Radiators of the German brand Kermi (Kermi) have become one of the most popular positions on the Russian market; they are willingly used today by many of our compatriots in heating their homes.

Kermi has indeed become a recognized leader in its 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 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 where the pressure is not as high as in the city. Steel radiators are dangerous water hammer; bimetallic batteries are capable of holding pressure up to 30 atmospheres.

In order not to take up your time describing their external advantages, I suggest watching a short video about these devices below, so you can get your own idea about them.

Consumers are interested 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 has an appropriate appearance: refined, elegant, noble. It cannot be said that they are cheap, but, they say, the costs are justified by a high degree of comfort.

In fact, the operation of any liquid radiator is built on the same principle - the coolant (in this case, it is water) enters the radiator tank and slows down, gradually cooling down and transferring heat to the room.

The main advantage of these devices is the high specific thermal power. So Kermi radiators are considered very powerful.

Batteries transfer heat by thermal radiation from the front surface and have a very decent heat dissipation. They are usually installed in autonomous systems heating, as they are designed for low operating pressure.

It is difficult to disagree with the fact that the appearance of Kermi brand radiators is quite aesthetic. Batteries come in various sizes. Mainly produced radiators white color, they are covered with a special powder coating (according to the manufacturer, environmentally friendly! I have not yet seen rebuttals, so it is quite possible, this is true), which seems to allow you to keep the temperature 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 engaged in the production of steel panel radiators. (By the way, since 1976, she has also been closely involved in the production of shower cabins). And by 1975. Kermi 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.

In the Russian market, these heating batteries proved themselves relatively recently, but they are trusted. Yes, and a 5-year warranty from the manufacturer, of course, captivates.

Specifications

Each of the pure white products of the Kermi brand 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 panels on the radiator is indicated on the marking:

type 10 - one panel;
type 11 - panel with fins;
type 21st - a pair of panels and one finning;
type 22 - a pair of panels and a pair of fins;
type 33 - three panels and three rows of fins.

Due to the enviable variety of standard sizes of radiators, they can be matched to any room and any place.

If for a massive radiator with dimensions of 300 x 2000 mm you need a fairly spacious room, and sometimes it is possible to assemble it almost on the street under the window, then compact models of Kermi radiators (for example, 45 mm in depth) are not at all difficult to mount at home.

Steel panel heating radiators of the Kermi brand are devices of impeccable quality, with high heat dissipation and stylish design.

Height in the range of 300-900 mm;
Length in the range of 400-3000 mm;
Kermi radiators are produced in single-layer, two-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 implies the circulation of the coolant simultaneously through two panels, in this case, uniform heating of the radiator surface is obtained. Not so long ago, a similar method of heating the coolant was considered the most rational.

But Kermi steel radiators, manufactured using the special Therm X2 technology, are made differently. The coolant in the radiators first passes through the front panel, and then it is fed through the pipes to the rear panel.

Such circulation of the coolant 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, which makes the panel 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 in this case plays the role of a good screen, thanks to which unnecessary heat losses are prevented and there is almost no useless energy consumption for heating the wall.

Power

When talking about the merits of Kermi, it is considered necessary to recall such an innovative technology that is patented by the company as ThermX2. It is due to the fact that the coolant in the battery first warms up the outer panel facing the room, and only after that it enters the rear panel, the device saves up to 11% of thermal energy.

Kermi Profil - Kompakt FKO panel radiators have a side or bottom connection. Kermi FKO devices with lateral connection are designed for space heating 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 any side (right or left). Kermi devices function well in heating systems based on forced circulation of the 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. Kermi radiators are equipped with special thermostatic valves.

Nothing prevents radiators from working in heating systems with any type of coolant circulation.
