Man, 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 to help him progress. Things and household items that surrounded a person, those with which he cooked food, heated a dwelling, etc., underwent various kinds of changes.

Their shape and appearance changed, they became easier and more practical to use. The goal is the same - to create the maximum comfortable conditions for the life of the one who invented and perfected these things. Let's take home heating as an example. This is a mandatory measure necessary for survival.

It all started with ordinary fires in caves, which were “fed” with firewood. Then the fires began to be covered with stones, which greatly simplified the possibility of cooking food on them. Further - more: hearths are laid out of stones, chimneys are made. Here is practicality for you, here is convenience and comfort for you.

In the age of modern technology, when we have mastered electricity, Kermi steel radiators have replaced the seemingly inconvenient and very bulky ones. And besides them, 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 do these radiators have? How difficult is the installation of each of the presented models, and how is it carried out? Read about all this below, the details are there.

At the very beginning, I would like to say that the Germans and quality are two interrelated things. We would like to proudly announce that Germany is the manufacturer of kermi radiators. German quality, and there is nothing more to add.

Kermi radiators can be divided into several groups, of course conditionally:

— aluminum radiators;
— steel heating radiators Kermi;
— bimetallic radiators;
– heating radiators, on which the designer worked;

Kermi radiators, designed by the designer, will harmoniously blend into the interior of your country house or cottages, beautifully complementing it with their presence.

In addition to the above division, there is one more:

— monolithic radiators;
— sectional radiators;

The undoubted advantage of sectional radiators is their compactness, due to small sizes they can be placed even in the most unexpected places. Fitting into the interior for sectional-type batteries is not difficult.

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

There are also varieties of Kermi radiators, moreover, they already differ in types. So there are:

- type radiators Kermi fko - side connection radiators

- type radiators Kermi fkv - with bottom connection.

A very convenient solution, thanks to which you can install it anywhere you want.

Steel radiators Kermi with side and bottom connection

The choice of radiators today is very, very large. Even the most fastidious and captious buyer will be satisfied. But among this set, it is still possible to single out radiators that are most popular compared to other models.

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

If there is a device that, the reaction of the radiator to its command will be immediate and prompt. The popularity of steel panel radiators is also explained by the fact that in their case there is an ideal price-quality ratio. If the question arises before you - which steel heating radiators are better, then choosing a German manufacturer, you will not be disappointed.

How to connect Kermi heating radiators

Installation of heating radiators is very important point, which should not be approached through the sleeves. Energy resources are now expensive, and therefore the heat that heating systems give us must be used rationally.

Here a few tips, which will help to realize all of the above:

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

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

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

Treat yourself to comfort and convenience, conduct Kermi heating by purchasing a sectional or monolithic water-type radiator with optimal technical characteristics. A huge selection of Kermi radiators, as well as everything for Kermi, is presented in online stores.

Required thermal power Kermi radiators depend on:

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

Determining the power of radiators based on the area

Building codes determine the average heat consumption per 1 m2 of the floor of the room - 100 W. This is a very approximate indicator, so they often resort to using the formula Q \u003d (2So + Sp + Sns) (0.54Dt + 22), where:

Q is the desired total heat transfer of radiators;
Dt is the difference between outdoor and indoor temperature;
So is the window area;
Sp - floor area;
Sns is the area of "street" walls.

When choosing the Kermi model (radiators), the power is calculated according to this formula, but taking into account the heat losses inherent in a particular room. Experts can determine the exact indicators.

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

According to building codes, one cubic meter rooms require the following heat transfer:

in panel buildings - 0.041 kW;
in brick - 0.034 kW.

For example, let's take a room in a brick building. Ceiling height - 2.7 m. Walls 3 and 5 m long. Room volume - 40.5 m3. To obtain an average power indicator, it is necessary to multiply the volume by a factor of 0.034 kW. The result of the product (40.5x0.034) is 1.377 kW (1377 W).

But this result is valid only for the middle climatic zone and without taking into account the correction, which depends on the number of external walls and windows. The illustration shows the dependence of the coefficients on the average winter temperature.

Some coefficients by which you need to multiply the average required heat transfer, depending on the number of external walls and windows, as well as taking into account the location of window openings:

1 outer wall – 1,1;
2 external walls and 1 window - 1.2;
2 external walls and 2 windows - 1.3;
windows "look" towards the north - 1.1.

If radiators are supposed to be installed in a niche, then for Kermi batteries, the power calculation is adjusted taking into account a factor of 0.5. If the thermal structure will be covered with a perforated panel, the average value should be multiplied by 1.15.

For example, in our conditional room with a volume of 40.5 there are two walls facing the street. At the same time, the average temperature in winter is -30. In this case, we multiply the obtained heat transfer by the required coefficients - 1377x1.2x1.5 = 2478.6 W. The rounded result is 2480 watts.

This number is relatively accurate, but the matter is not limited to the mentioned coefficients. Specialists in thermal calculations take into account what material the walls are made of, the characteristics of the rooms located around, etc. But, subject to average indicators, this number can be used. To determine the type of batteries, the Kermi radiator power table is used.

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

The table shows the power various radiators brand. Red highlighted values suitable for our case. These batteries can be installed indoors with similar characteristics.

But for Kermi radiators, the power table only works if the average values \u200b\u200bof the temperature of the coolant and air in the room are observed:

coolant t (supply) - 70 degrees;
coolant t (return) - 65 degrees;
t air - 20 degrees.

If the system characteristics differ from the average, it is required to multiply the received power by another factor. The latter can be determined using a table.

To create warmth and comfort in their home, many choose Kermi brand radiators. This is a German company that produces different models steel panel radiators for more than half a century. Despite their compactness, they have excellent heat transfer performance. And attractive appearance allows you to fit batteries into any modern interior.

The most popular model is Kermi 22 500 500 . The device consists of two steel panels, between them there are two convectors, which are made in the form of U-shaped fins. Distinctive feature- application in the manufacture of batteries of the unique Kermi Therm x2 technology. Due to the special design, the coolant first enters the front panel, so that the air in the room is heated first. The back panel heats up later and works like a screen.

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

Specifications Kermi 22 type:

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 closed heating systems. In this case, the circulation can be natural or forced, the system is one- or two-pipe.

Upon purchase, the device package includes a plug, a Mayevsky valve - a valve for bleeding air, a set wall mounts. IN radiators Kermi 22 type with bottom connection built-in thermostatic valve, which allows you to install equipment to control the air temperature in the room.

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

Externally, the radiator looks modern and stylish. It will not only heat your home, but also become stylish part interior. The ideally white surface is a lacquer coating that, when heated, does not release toxic substances into the air. On the sides, the radiator is closed with solid panels, and on top - with a grille.

By favorable price!

Models with a bottom connection to a hidden pipeline, Kermi FTV 22 are primarily in demand in private housing construction, as they are suitable for work in autonomous system with forced circulation.

It is the most popular model of panel radiators due to its optimal performance at minimum cost.

By its design, the Kermi FTV 22 type steel radiator is a system of two flat panels, between which two convectors are installed in the form of U-shaped fins. The installation depth is 100 mm. All elements that make up Kermi radiators are made of high-quality steel with a reliable anti-corrosion coating.

Special processing inner surface, prevents sedimentation of contaminants. The outer decorative and protective layer is subjected to high-temperature heating to gain strength. Before you buy Kermi FTV 22 type radiators with a bottom connection, you need to decide on the dimensions of the heater in order to ensure the optimal level of heating of a room of a certain volume.

Radiators Kermi FKV 22 type bottom connection

When assembling the panel from profiled steel sheets, as well as fastening between the channels is carried out by the method spot welding. A continuous or roller seam is performed around the perimeter. This technology guarantees high strength and tightness of radiator panels. To check the quality of seams ready product Kermi FKV 22 type, like Kermi 11 type, is subjected to a corresponding load - the liquid is supplied to the radiator at a pressure of 13 bar, as during pressure testing of the installed heating system.

To place an order, contact the managers of our company by phone or place an order on the website.

The package of panel radiators includes brackets for fixing the device to the wall.

FKV batteries withstand heating of the coolant up to high temperatures(up to 110°C), functions properly at operating pressure up to 10 bar and is able to withstand peak loads up to 13 bar. To avoid corrosion under the influence of oxygen dissolved in the coolant, steel panel radiators are recommended to be used as part of closed-type heating systems with any organization of the coolant movement.

When planning to buy Kermi with a bottom connection, it is necessary to perform a thermal calculation of the room and take into account the features of the placement of the heating device. The product line includes KERMI FKV radiators of various capacities with a height of 300-900 mm and a length of 400-3000 mm. The installation depth of the battery depends on its type - the models differ in the number of panels and rows of convective fins.

The material for the manufacture of heating devices is cold-rolled sheet steel, the thickness of which is 1.26 mm. Panels with a corrugated surface are welded from two stamped sheets with a continuous roller seam. The tightness of finished radiators is tested at the factory under peak pressure.

Hollow panels, through which the coolant circulates, radiate thermal energy. U-shaped finning promotes intense convection, due to which the volume of air in the room warms up faster. Powerful panel radiators with fins are suitable for installation in rooms with a large glass area.
