The Kermi brand 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 you to use not only in individual systems, but also district heating(with some restrictions).

Design features

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

Kermi batteries are made in the same way. Their order of supplying the coolant differs. All have it parallel. This means that liquid of the same temperature is supplied to all panels in the radiator. This feeding method works very well with high temperature online. But as soon as the temperature drops (warming, for example), the radiators become almost cold.

In panel radiators "Kermi" the supply of the heat carrier is sequential and this technology is called Therm-X2. This means that the hottest flow 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 colder and colder. In this case, most of the heat goes into the room, and the non-production costs for heating the wall behind the radiator are much lower. Therefore, at the same temperature of the coolant and the same size, Kermi batteries heat up the room 25% faster.

The new Therm-X2 technology makes it possible to warm the room well even in low temperature conditions 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,.

Another novelty is used in these radiators. The firm sets up balanced. The balancing parameters were determined as a result of research. All steel radiators with bottom connection supplied from the factory with balanced and preset thermostats (thermal head must be purchased separately). By installing such a heating device, you get a stable temperature in the room: the amount of heat carrier is supplied to the collector, which is required to maintain the temperature. You need to change the setting if you are not satisfied with the set mode. Using a thermostat is more than just comfort, for individual systems it is also an opportunity to save money: it is spent on heating only the right amount fuel.

There are some other features in the connection of 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 do 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).

Panel radiator models Kermi

There are two main types: smooth and profiled. Smooth ones have an absolutely flat front panel - called Plan, profile ones - 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 bottom connection, and in three versions: left, right, or in the center.

Plan-K models are a side-connected version (FKV marking). In this group there is an option for replacing old ones cast iron radiators- with a center distance of 500 mm and 900 mm. In this case, it will not be necessary to digest the liner (if the pipes are in good condition).

Radiators FKO and FKV 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 ribs and covers. Such models are required for medical institutions or for those with allergies. A large number of the ribs contribute to the accumulation of dust, and the small distances between the plates make cleaning difficult. The hygienic option is free from this disadvantage.

There is an unusual Kermi Verteo Plan. It is a vertical, sleek panel radiator. It will come in handy in cases where it is not possible to find a place for installing a wide radiator. But it must be borne 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 bottom (V) and side (K) connections. There is also a modification of the vertical radiators Verteo Profil. The types of these panel batteries are the same, with a slightly shallower depth (2-3mm).

Radiators "Kermi": characteristics

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

• Working pressure up to 10 Bar;
• Testing up to 13 bar;
• Maximum coolant temperature +110 o C;
• Inlet connections 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, how to connect - side and bottom, how to connect different types pipes and what is needed for this.

Features of operation

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

There is only a plastic Kermi logo on the side panel. So he serves as a key. Pull the left edge of the logo towards you, turn it down a little. The hole opens. But the logo still needs to be rotated counterclockwise until it unscrews (it is screwed 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 a ridge-fixer, which can scratch the paint. After removing the logo, you can pull the side plate down to release it from the clips. If there is a valve in the model, first remove the left panel, there is a valve on the right and interferes. After the sides have been removed, the lid does not hold anything. Can be cleaned.

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

A person, since ancient times, has always strived to provide himself with the most comfortable living conditions, equipping his life. Actually, due to this kind of aspirations, conditions were created that help him progress. The things and household items that surrounded a person, those with which he prepared food, heated his home, etc., were subjected to various kinds of changes.

Their shape and appearance changed, they became simpler and more practical to use. The goal is one - to create the maximum comfortable conditions for the life of the one who invented and improved these things. Take home heating as an example. This is a must-have measure for survival.

It all started with ordinary fires in caves, which were "fed" with wood. Then they began to lay stones around the fires, 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.

In the age of modern technologies, when we mastered electricity, steel radiators of Kermi replaced the seemingly inconvenient and very bulky ones. And besides them, kermi panel steel radiators, distinguished by their compactness and high performance.

Kermi radiators: table of types and distinctive technical characteristics

So, what are Kermi steel 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, details 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 the producer 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:

- aluminum radiators;
- steel radiators for heating Kermi;
- bimetallic radiators;
— heating radiators that the designer has worked on;

Radiators Kermi developed by the designer will harmoniously blend into the interior of your country house or summer 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 their small size they can be placed even in the most unexpected places. It is not difficult to fit into the interior for sectional batteries.

But there are also disadvantages - rubber gaskets. When using, for example, antifreeze, the gasket quickly deteriorates and needs to be replaced. Sectional type radiators include bimetallic and aluminum radiators.

There are also varieties of Kermi radiators, moreover, they differ in 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 carry out installation anywhere you want.

Steel radiators Kermi with side and bottom connections

The choice of radiators today is very, very large. Even the most fastidious and picky buyer will be satisfied. But among this set, one can still distinguish the radiators that are most popular in comparison with other models.

I would like to present to your attention steel radiators Kermi... These water radiators are used mainly in country houses or at dachas, this is due to the fact that they are not designed for great pressure... Thermal inertia of Kermi panel radiators is low, but heat transfer, on the contrary.

If there is a device that is available, the response 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 a question arises before you - what are the best steel heating radiators, 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 carelessly. Energy resources are now expensive, and therefore the heat that heating systems give us must be used rationally.

Here some tips that will help bring all of the above to life:

- no matter what your Kermi water heating radiator is made of, it should be placed under the window. This can be explained very simply: the cold air currents coming from the windows will be blocked by the warm currents emitted from the batteries.

- decorating radiators with panels will deprive the room of at least 15-20% of the heat;

- place behind the radiator a couple of thin metal plates equipped with. The efficiency will increase significantly.

Give yourself comfort and convenience, heat 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 the online stores.

Required thermal power Kermi radiators depend on:

• room area;
• the volume of the room;
• heat loss of the room;
• characteristics of the heating system.

Determination of the power of radiators, based on the area

Building codes define average consumption heat per 1 m2 of the floor of the room - 100 W. This is a very approximate indicator, therefore, they often resort to using the formula Q = (2So + Sp + Sns) (0.54Dt + 22), where:

• Q is the required total heat transfer from the radiators;
• Dt is the difference between outdoor and indoor temperatures;
• So is the area of ​​the windows;
• Sp is the floor area;
• Sns - the area of ​​the "street" walls.

Choosing the Kermi model (radiators), the power is calculated using this formula, but taking into account the heat loss inherent in a particular room. The exact indicators can be determined by specialists.

Determination of the power of radiators based on the volume of the room

According to building codes, one cubic meter premises require such 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 an average power indicator, the volume must be multiplied 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 outer 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 corrected taking into account a factor of 0.5. If the heating 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. Wherein average temperature in winter - -30. In this case, the resulting heat transfer is multiplied by the necessary coefficients - 1377x1.2x1.5 = 2478.6 W. The rounded result is 2480 watts.

This number is relatively accurate, but the factors mentioned are not limited. In thermal calculations, specialists take into account what material the walls are made of, the characteristics of the premises located around, etc. But, provided that the average indicators are used, this number can be used. To determine the type of batteries, the Kermi radiator capacity table is used.

Choosing the type of Kermi radiator taking into account the required power

The table shows the power of various radiators of the brand. Values ​​suitable for our case are highlighted in red. These batteries can be installed in a room with similar characteristics.

But for Kermi radiators, the power table works only if the average temperatures 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 one more 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 on Russian market positions; many of our compatriots willingly use them today in heating their homes.

Kermi has truly 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 the traditional for it 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. Water hammer is dangerous for radiators made of steel; bimetallic batteries are capable of holding pressure up to 30 atmospheres.

In order not to waste your time, describing their external advantages, I suggest watching a short video about these devices below, so that you can form your own idea of ​​them.

Consumers have an interest in different models, including decorative batteries with unusual stylish designs.

The heating equipment of the Kermi series of radiators is mainly intended for individual houses and cottages, and has a corresponding appearance: refined, elegant, noble. This is not to say that they are cheap, but, they say, the costs are justified by the high degree of comfort.

In general, the work 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 to the room.

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

Batteries transfer heat by radiation from front surface and have a very decent heat dissipation. They are usually installed in autonomous systems heating, since 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. The batteries have different sizes... Produced mainly radiators white, they are covered with a special powder coating (as the manufacturer claims, environmentally friendly! I have not yet met refutations, 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 engaged in the production of shower cabins). And by 1975 Kermi achieved a leading position in this segment. Of course most of all Kermi know 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. And the 5-year manufacturer's warranty certainly captivates.

Specifications

Each of the white Kermi products on the market is equipped with a side panel and a top grill. Each battery is tested at the factory at a pressure of 10-13 bar before being placed on the market.

In the kit with the device itself, the manufacturer also supplies special air vent plugs and attaches brackets.

The number of panels at the radiator is indicated on the marking:

• type 10 - one panel;
• type 11 - ribbed panel;
• type 21 - a pair of panels and one ribbing;
• type 22 - a pair of panels and a pair of fins;
• type 33 - three panels and three rows of ribbing.

Thanks 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 difficult to mount at home.

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

• Height in the range of 300-900 mm;
• Length in the range of 400-3000 mm;
• Kermi radiators are manufactured in single-layer, double-layer and three-layer.

Steel panel radiators Kermi are constructed as a pair of panels connected metal pipes where the heated coolant flows. The design of conventional radiators implies the circulation of the coolant simultaneously over 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 the 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 piped to the rear panel.

Such a circulation of the coolant contributes to a 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, due to which the panel warms 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 waste of energy to warm up the wall.

Capacities

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

Panel radiators Kermi Profil- Kompakt FKO is provided for lateral 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 appliances function well in heating systems based on forced circulation coolant.
Radiators Kermi Profil - Ventil FKV, with a base bottom connection, are designed to work in a variety of heating systems at any temperature of the heating medium. Special thermostatic valves are installed in Kermi radiators.

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

Installation of Kermi radiators

Note for buyers about Kermi Type 22 radiators, characteristics, reviews, questions. Differences between Kermi FTV and Kermi FKV 22. Features of battery coverage. An example of calculating the center distance for Kermi radiators.

To create warmth and comfort in their home, many choose Kermi brand radiators. it German company issuing different models steel panel radiators for more than half a century. Despite their compactness, they have excellent heat transfer rates. And the attractive appearance allows the batteries to fit 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 a U-shaped ribbing. Distinctive feature- the use of the unique Kermi Therm x2 technology in the manufacture of batteries. Thanks 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 acts as a screen.

By the way, before the introduction of the Therm x2 innovation, Kermi radiators with bottom connection had the abbreviation FKV, but they have already been discontinued.

Specifications Kermi 22 type:

• The maximum temperature of the coolant is 110 degrees Celsius.
• The power depends on the size. With a temperature regime of 90/70/20 and dimensions of 500x500 power radiators Kermi 22is 965 W.
• Working pressure - 10 atmospheres.
• The maximum pressure test is 13 atmospheres.
• Thickness - 100 mm.
• Height - from 200 to 900 mm.
• Width - from 400 to 3,000 mm.
• Center-to-center distance - for FKO, you need to subtract 54 mm 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 Kermi white RAL 9016

There are two versions depending on the type of connection.

1. RadiatorsKermi FKO 22... These are side-connected models with piping 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 the manufacture of these devices, as well as due to their high aesthetic qualities, the cost of Kermi FTV is higher.

Regardless of the type of connection, steel radiator Kermi Type 22 recommended for installation in heating systems closed type... In this case, circulation can be natural or forced, the system is one- or two-pipe.

A plug, a Mayevsky valve - a valve for bleeding air, a set of wall mounts are included in the package of the device upon purchase. V radiators Kermi 22 type with bottom connection built-in thermostatic valve, which allows you to install equipment for regulating the room temperature.

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 perfectly white surface is a varnish coating that, when heated, does not emit toxic substances into the air. On the sides, the radiator is covered with solid panels, and on top - with a grill.
