Kermi steel radiators technical specifications. Radiators "Kermi" - excellent quality and characteristics. Steel panel radiator Kermi

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, technical 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—corrugated steel sheets of small thickness—can be welded to them. They are located behind the front panel and do not spoil appearance, and 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 feeding method works very well at high network temperatures. 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 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 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: only the required amount of fuel is spent on heating.

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 wiring without being tied to the availability 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. Large quantity ribs contribute to the accumulation of dust, and small distances between the plates complicate cleaning. The hygienic option does not have this drawback.

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 output depends on the 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. In addition, in 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 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.

Kermi is a German sales representative belonging to the renowned AFG Arbonia-Forester-Holding AG. This structural division deals with radiators. Due to decent quality and excellent performance indicators, the demand for products remains stable. It is worth taking a closer look at the characteristics and subtleties of installing the units.

Peculiarities

The German company Kermi was founded in 1960. The main type of products produced are steel panel radiators, although the manufacturer is also known for shower cabins. However, it is German radiators that have gained wide popularity not only in Germany, but throughout the world. Russian buyers also liked the appearance of German batteries. An important component of success was the quality of the products.

The features of the radiators include two types of connection, as well as three different metal thicknesses. In addition to steel products, bimetallic options are available to customers. Russian consumers especially liked products designed for installation in individual houses and cottages. The appearance of the devices is refined, noble and elegant. The units are not cheap, but consumers note the return on costs, as well as a high degree of comfort.

The operating principle of any radiators is based on the coolant circulating inside the device. The liquid entering the radiator tends to slow down its movement from device to device and also cool down. As a result, less heat is transferred into the room. The main feature of German radiators is their increased heat output characteristics. The heat transfer from the front surface of the installed batteries is quite decent. Therefore, Kermi radiators are ideal for autonomous heating systems with low operating pressure.

The company offers batteries in various sizes. The main models on sale are white. According to the manufacturer, the powder coating of products is environmentally friendly. It is also claimed that this special coating allows for better temperature retention of devices. Decorative models found on sale differ from the main line in color and design features.

The main type of products manufactured by Kermi are panel radiators, consisting of steel plates connected in pairs. The coolant in such radiators moves through channels extruded by stamping. Usually there are several channels for circulating fluid. One of them is located at the top, and the other is at the bottom. There are several paired plates assembled in a steel product.

To increase efficiency, some models contain convective fins - these are corrugated steel sheets that are small in thickness and are usually welded behind the front panel. Externally, this usually does not change anything, but the sides and top of the product are decorated. Some Kermi batteries have a different media supply method. The Therm-X2 technology is considered consistent and renowned. In practice, hot liquid is supplied first to the front part, then to the subsequent ones. As a result, the hottest part is the part facing the rooms.

Greater heat consumption occurs in the room. There is much less other heat consumption with this connection. In practice, Kermi series-type batteries heat the room faster than other types of devices. The devices showed a special heating quality when pumps and collectors were connected to the system. The company installs control valves on its devices. The new product allows you to optimally balance a stable temperature in all rooms. Basically, steel radiators from other manufacturers are supplied with thermostats, but the thermal head must be purchased separately. Kermi radiators add comfort to individual heating systems. The system consumes only a adjusted amount of fuel, which significantly reduces costs.

In addition to the sequential version, Kermi batteries have the possibility of a side and bottom version. The lower supply can be either left or right, or it can also be in the center. Therefore, the installation of heating pipes can be done as conveniently as possible, without taking into account the features of the heating device. Installation of devices can be carried out after finishing is completed, it is only advisable to secure the brackets on the wall in advance. It is worth considering in more detail the technical characteristics of the main types of radiators produced by the company.

Species

Kermi radiator buyers face difficult task choice. The large range of indicators forces us to study the technical characteristics in more detail. The designs and size range of devices are different. Specific data is also related to the design of the units. For example, heating radiators on sale range from 40 cm to 3 meters in length, the height of the radiator is from 30 to 90 cm.

Tubular, panel, and finned options are common. Panel steel appliances from this company come with one, two and three panels. The three-layer design is considered the most powerful. Devices are also divided into types, which are related to the number of panels. The table includes 10 to 33 product types. For example, the first is the 10th type, which includes one such part, the 11th type includes an addition in the form of ribbing, the 12th type - thin batteries 6.5 cm wide, the 22nd type - two panels and double ribbing. Type 30 and above include batteries with three rows and triple fins.

Batteries with a corrugated surface belong to the Profil category, and smooth radiators with a flat front panel are called Plan. In the group of smooth devices there are also various options, differing in characteristics and markings.

Plan-V options are designated FKO - these are radiators with a lower supply option, known to customers in the following three types:

left-handed;
right-sided;
centered.

Plan-K models marked FKV are distinguished by lateral inlet. The association includes suitable options for replacing old cast iron radiators with a distance between the axes from 50 to 90 cm. If the pipes are in normal condition, replacing them with these devices does not require their digestion.

In the group of smooth devices of the V series there are hygienic models without additional ribs and covers. These options are good for medical institutions, as well as where there are allergy sufferers.

Another unusual option is Verteo Plan. This product vertical type necessary in cases where installing a horizontal version of the required power is impossible. FTV radiators are newer models that replaced the FKV variants. The models are equipped with a bottom connection option and allow the installation of a hidden pipe system. Communications for these products can be placed under the floor base. The radiators are distinguished by a two-layer varnish coating. Treatment inside and outside protects products from corrosive destruction.

Line radiators from Kermi have an excellent external design. Included in the line wide range installation dimensions. Radiators of this type are easy to install. These radiators successfully combine excellent design and functionality of the devices. Models differ high performance. The heat transfer of steel radiators mounted in the wall is comparable to bimetallic options. Replacing energy-consuming options with cost-effective batteries is easy and simple. It is enough to make the necessary calculations.

Calculation

To make the correct calculation, you can compare the dimensions of a classic cast-iron 12-section battery with a heat output of 1444 W. The internal volume of the unit is 13 liters. Technical standards Kermi batteries assume a heat transfer efficiency of 2100 W, while the working volume of the unit is 6.3 liters. The indicated heat dissipation refers to a single-section battery. These data are indicated in the passport of type 10 products.

It is known that if the system contains a large volume of coolant, this usually leads to large heat losses. This is inevitable, since the system has many elements. Even carefully isolated systems with large volumes of media are not 100% efficient. The technical characteristics of Kermi radiators are advantageous due to the fact that a smaller volume of media can be passed through the pipes. To pass the same amount of heat in a cast iron system, a very large volume of media must be passed through the pipes. With this volume pumping equipment will receive a very high load.

Other technical characteristics that are useful when creating a connection diagram are as follows:

working pressure – 10 bar;
test pressure – 13 bar;
maximum temperature readings – +110 degrees;
outlet openings – ¾ and ½;
Thermal output is usually related to the type, height and length of the radiator.

It is more convenient to calculate this parameter using a table usually provided by the manufacturer, for example, if you decide to install one of the models from the popular Kermi Therm X2 Plan line. All models produced by the manufacturer are available in the table, so in the selection process all that remains is to find the appropriate values. Experts allow slightly higher values than calculated for a specific system. In the table, it remains to indicate radiators of acceptable height and length. To calculate the exact power, you need the heat loss values of the room, the temperature of the supplied medium, and the desired room temperature. This data will help more accurately determine models that will fully satisfy the system conditions. All should be noted in the table possible options, suitable for power, then decide on the appropriate parameters of the product.

You can make an approximate calculation for a system with an initial temperature of +60 degrees, a return temperature of +50 degrees. Inside it should be about +22 degrees. Delta will be calculated as follows: (60+50) /2-22=33. In the table with coefficients for the indicator in the room +22 degrees, the applied coefficient is 1.75. Heat loss for the room will be: 2150*1.75=3719.5. Suitable options radiators by power can be determined from the power table.

For example, you can choose models of the following dimensions:

with a length of 3005 mm, the permissible height of the product will be 305 mm;
with a length of 2305, 2605 mm, the height of the product can be 405 mm;
with a length of 1805, 2005 mm, the permissible height of the product is 505 mm;
with a length of 1605 mm, the permissible height of the product is 605 mm;
with a length of 1405 mm, the permissible height of the product is 905 mm.

From the range of products that are suitable for this system, it is worth noting the following models:

Kermi Therm-x2 FKV – the radiators presented in the line have a height from 300 to 900 mm, a length from 400 to 3000 mm;
Kermi Therm-x2 FKO have identical overall dimensions. The difference lies in the connecting thread of the pipe - 4x1/2. The connecting thread of the first option is 2x3/4.

Installation

Installation of Kermi radiators is not difficult, but each job has its own nuances. For example, when there is no need to replace pipes, adapters will help solve the problem with different diameters of communications and radiator outlets. The instructions will help with more competent installation. It is convenient to study the connection nuances using the diagram supplied with the product. For example, it states important point with the connection of a separation plug, which ensures the functioning of Therm-x2 technology.

The installation process also involves two types of connections, which means the installation schemes can be bottom and side.

It is important to choose the optimal location depending on the type of installation; the manufacturer’s recommendations are as follows:

100–120 mm from the floor covering;
80–100 mm from the window sill.

In both cases, this distance will provide the most efficient heat transfer. If the radiator is located 20–50 mm from the vertical, then there will be no energy loss for gentle heating of this area.

Distinctive feature company is that the batteries are supplied in stores with all the necessary components for installation. The heating device is presented in a branded box. The packaging may not be removed during installation, thereby leaving the device intact.

The standard Kermi kit includes the following items:

loops;
corner clamps, console;
grill top;
covers and damping sides;
Mayevsky crane;
thermostatic tap;
instructions for installation and use.

The stages of attaching radiators can be presented in the following order:

choosing a location for the device taking into account optimal heat transfer;
marking under hooks;
fastening of auxiliary fittings;
fixing the radiator on hooks;
device alignment;
connecting the device according to the diagram to the pipes;
pressure testing - testing a system that can be hydraulic (water) or pneumatic (air);
commissioning work, during which it is important to check the tightness.

As you can see, heating devices German manufacturer very detailed and thoughtful installation diagram. That's why self installation It is unlikely to seem difficult even to a non-professional.

A note for buyers about Kermi Type 22 radiators, characteristics, reviews, questions. Differences between Kermi FTV and Kermi FKV 22. Features of battery coating. 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 heating radiators for more than half a century. Despite their compactness, they have excellent heat transfer performance. 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 fin. Distinctive feature– 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 connections had the abbreviation FKV, but they have already been discontinued.

Specifications Kermi type 22:

The maximum coolant temperature is 110 degrees Celsius.
Power depends on size. At a temperature of 90/70/20 and dimensions of 500x500 power radiators Kermi 22is 965 W.
Working pressure – 10 atmospheres.
The maximum testing pressure is 13 atmospheres.
Thickness – 100 mm.
Height – from 200 to 900 mm.
Width – from 400 to 3,000 mm.
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 – white Kermi RAL 9016

Depending on the type of connection, there are two options.

1. RadiatorsKermi FKO 22. These are models with side connections, pipes are connected to 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 baseboard. Due to the increased complexity of manufacturing these devices, as well as their high aesthetic qualities, the cost of Kermi FTV is higher.

Regardless of connection type, 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.

The purchase package of the device includes a plug, a Mayevsky valve - a valve for bleeding air, and a set of wall mountings. IN Kermi radiators type 22 with bottom connection A thermostatic valve is built-in, which allows you to install equipment to regulate the air temperature in the room.

Kermi panel radiators have an advantage over their analogues - they are coated with iron phosphate and two layers of varnish. This treatment significantly increases the service life!

Externally, the radiator looks modern and stylish. It will not only warm your home, but will also become a stylish part of the interior. A perfectly white surface is a varnish coating that, when heated, does not release toxic substances into the air. The radiator is covered with solid panels on the sides and a grille on top.

Among the brands producing steel heating devices, the undisputed leader is the German brand Kermi. The products of this company are distinguished by high quality, reliability and implementation modern technologies aimed at maximizing energy consumption reduction. In this article we will review the types and technical characteristics that distinguish Kermi steel radiators.

Innovative Kermi radiator design

If the story about radiators is replete with cliches like: “made of the highest quality sheet steel using the latest technology,” or “durable powder coating in any color,” then you will quickly become bored.

You say - this is written on the website of any battery manufacturer, everyone praises their products. And you’ll be right, they write everything well, but how everything is actually done is a question. Therefore, let’s move straight to the specific feature that distinguishes Kermi panel radiators from all others.

It would seem, what other solutions can be implemented in heating devices, when everything that is possible has already been invented? It turns out not all. The Germans added internal piping to the radiators. This allows you to heat only the front panel of the device in normal mode; no water circulation occurs in the rear part. But as soon as the room temperature drops, the built-in thermostat will open the way for coolant to the rear panel, bringing the radiator to full power. Otherwise, these are ordinary steel batteries, only very reliable and made in compliance with the highest quality requirements.

Note. In connection with the implementation new technology Alternating supply of coolant to the front and rear parts, the Kermi radiator received the prefix “therm X2” in its designation.

Types and characteristics of Kermi heating devices

At the moment, the brand offers the following types of traditional steel batteries:

profile therm X2 profil K (compact) and Profil V (valve);
smooth therm X2Plan K (compact), Plan V (valve), Verteo Plan (vertical);
with horizontal profiling of the front panel therm X2 line K (compact), Line V (valve), Verteo Line (vertical).

As for the types of radiators offered, all standard types are produced under the Kermi brand, from 10th to 33rd. Let us recall that the first digit in the designation indicates the quantity heating panels, and the second – on the number of convective fins. The most popular is type 22, where 2 panels and the same number of fins are used, as shown in the figure:

General technical characteristics of Kermi radiators are presented in the table below:

The listed 3 types of batteries differ in appearance by the type of profiling or lack thereof. While their heat transfer rates are somewhat different. It should be noted that the power of Kermi radiators is declared by the manufacturer in relation to the installation length. Therefore, first we present a table of the thermal power of 1 m of profiled devices (therm X2Profil) depending on the height, type and operating temperature curve of the coolant:

Note. Since steel batteries vertical type Kermi therm X2 Verteo are used much less often than traditional ones, we will not give their characteristics here. The corresponding tables can be studied on the manufacturer’s Internet resource.

Connection diagrams

All three types of products provide side and bottom connections for Kermi radiators, and the pipes for connection from below can be located in three options to choose from: right, left and middle. The bottom connection method is provided in all valve devices (at the end of the designation there is a Latin V), and the side connection method is provided in compact ones (the letter K in the designation). The internal wiring is clearly visible on bottom-connected batteries:

For reliable operation of its products and the full functioning of the X2 series connection effect, the manufacturer requires connection to be made in accordance with certain requirements.

A diagram of how radiators with side connections should and should not be connected is presented below:

Advice. After purchasing and installing the Kermi battery in its place, carefully read the instructions that came with it. It describes in detail how to correctly install the separation plug in the return line of the device when it is operating in a one- or two-pipe heating system. This plug provides the X2 function (sequential switching of panels), so there is no mistake here.

It is also possible to connect a radiator from different sides from below, as is customary to do in the popular one-pipe heating system “Leningradka”. But in this case, the separation plug is not installed, the X2 effect does not work, and the heat transfer value of the battery is reduced by 8%.

Valve heating devices, in which the connecting pipes are located at the bottom, are not allowed to be connected from the side on any side, but only as required by the manufacturer. The following figure shows the installation diagram of a radiator with a bottom connection:

In a situation where, when replacing old heating devices with new ones, the center distances of Kermi batteries may differ from the previous ones, the situation can be corrected using special adapters. Their installation allows you to adjust the distance between pipelines without dismantling or altering them.

Conclusion

Kermi radiators are a high-quality product manufactured using high technology, and therefore a priori cannot be cheap. This is the only drawback of these devices that you will have to come to terms with if you want to have warmth and comfort in your home for many years.

Technical characteristics and connection

Radiators of the German brand Kermi (Kermi) have become one of the most popular positions on the Russian market; Today many of our compatriots readily use them to heat their homes.

Kermi have truly become a recognized leader in their segment. Their steel panel radiators (and not only) have become widely known in the world, and popularity, as you know, is the second component of success. And quality. Today the company produces not only its traditional steel batteries, but also bimetallic ones. They have two types of connection - bottom and side. And three different thicknesses 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 propose below to watch a short video about these devices, thanks to which you can form your own idea about them.

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

The heating equipment of the Kermi series of radiators is mainly intended for individual houses and cottages, and have a corresponding 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 in white color, they are coated 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 you to maintain 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 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.

These heating batteries have appeared on the Russian market relatively recently, but they are trusted. And the 5-year warranty from the manufacturer is certainly captivating.

Characteristics

Each of the Kermi brand's snow-white products launched on the market is equipped with a side panel and a top grille. Each battery is tested at the factory at a pressure of 10-13 bar before entering the market.

Complete with the device itself, the manufacturer also supplies special air vent plugs and brackets.

The number of radiator panels is indicated on the marking:

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

Thanks to the enviable variety of radiator sizes, they can be selected to suit any room and any location.

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

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

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

Kermi steel panel radiators are designed as a pair of panels connected metal pipes where the heated coolant flows. The design of conventional radiators involves the circulation of coolant simultaneously through two panels, in this case the result is uniform heating of the radiator surface. Not so long ago, such a method of heating the coolant was considered the most rational.

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

Such coolant circulation contributes to faster heating of the front panel, which increases the power of the actual thermal radiation. A slightly cooled coolant circulates in the rear radiator panel, causing the panel to warm up a little longer.

Should 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 advantages of Kermi, it is considered necessary to remember such innovative technology, which is patented by a company like ThermX2. It is precisely due to the fact that the coolant in the battery first warms up the outer panel facing the room, and only after that it enters the rear panel, the device provides thermal energy savings of up to 11%.

Kermi Profil - Kompakt FKO panel radiators have a side or bottom connection. Kermi FKO devices, having a side connection, are intended for heating rooms as in standard heating systems with coolant temperatures up to 110 degrees. C, and in systems with lower temperature indicators.

Kermi batteries can be connected to the system from either side (right or left). Kermi devices function well in heating systems based on forced circulation of 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.
