Features of operation of panel heating radiators
Features of operation of panel heating radiators
Steel has low corrosion resistance. Therefore, experts prohibit draining the coolant until the end of the heating period. It is permissible to do such a procedure for short periods of time, for example, to repair or make changes to the network. Short-term emptying and filling of the radiator have a negative effect. Therefore, it is recommended that all necessary repairs be carried out at one time.
It is also not recommended to turn off steel batteries with taps. The interaction of a metal with a liquid gives a chemical reaction with the release of gases. Therefore, when installing radiators, an air vent (the so-called Mayevsky crane) is required.
An air vent is a special manual valve for venting air. If you do not bleed air in time, the radiator will cease to function normally. There are also valves with an automatic mechanism that allow you not to monitor the air level in the radiator. Check Availability air chambers in the system can be on the top of the radiator - it remains cold.
Panel heating radiators
No matter how banal the paradox may seem, but in summer it is worth thinking about a warm winter. If you need to install a new heating system or upgrade an old one, this issue must be resolved while it is warm and the heating season has not begun. Otherwise, you will have to do a lot of expensive and dreary work in order to replace the batteries during the heating season.
Today there are many types of batteries. They differ not only in the material of manufacture, but also in many other factors, including the design. It would seem that something complex or new can be invented in a battery, but, by no means, manufacturers of heating elements will easily challenge this assumption.
Panel radiators
This type is not very common, now there is more and more demand for sectional battery options, as they are easy to supplement and adjust to individual requirements for the location of the heating element in different places in the room, because standard square rooms have long become relics of the past.
Panel heating radiators are made from steel sheets, which is why they are also called steel panel radiators. Such batteries are also called convectors, because of the special convector fins. The efficiency of such a heater does not exceed 75%.
The design itself is quite intricate: convector fins are located inside, and one or more steel heating panels are located outside, their number depends on the brand of the radiator. Inside the panels, the coolant moves through special channels. A protective grille is placed on top of the radiator, through which most of the heated air escapes due to convector fins.

Panel heating radiators are produced mainly by European countries:
- Germany - Buderus, Kermi;
- Czech Republic - Korado;
- Italy - DeLonghi;
- Finland - PURMO.
Prices for steel panel radiators are quite high, which is why Russian manufacturers are practically not interested in their manufacture.
But, despite this, metal panel radiators are the most budget option for autonomous heating systems of private houses.
Depending on the number of heating panels and convection fins, metal panel radiators are classified according to the types of ratio:
- Type 10 - single panel, but without convector fins;
- Type 11 - single panel with convector fins;
- Type 20 - two-panel, without convector;
- Type 21 - two-panel with one convector;
- Type 22 - two-panel with two convector fins;
- Type 30 - three-panel and without convector;
- Type 33 - three-panel with three convector fins.
Advantages and disadvantages of panel radiators
The benefits include:
- due to low inertia - high heat transfer;
- due to the small volume of channels, less coolant is used, as a result of which little energy is consumed;
- there are models with a low price, but, as a rule, the type is single-panel;
- environmentally friendly and harmless, which allows them to be used in hospitals, schools and childcare facilities;
- after purchase, the panel radiator is completely ready for installation, thanks to the integrity of the structure, which will require the owner only to hang the battery on special fasteners in the wall and connect it to the pipes of the heating system;
- have fairly high technical characteristics;
- steel has very good thermal conductivity, which increases heat transfer.
The disadvantages are:
- a very rapid process of corrosion formation begins if water is completely pumped out of the system and air is let in in its place;
- in multi-storey buildings of apartment complexes, you should not install such batteries, since they do not tolerate water hammer very well, with which each heating season begins in centralized heating systems;
- the integral design of the radiator can also be regarded as a disadvantage, because if there is a leak or other mechanical failure of the heating element, you will have to change the entire battery, and not just replace the section, as in options with other batteries;
- due to convection, dust will not accumulate in the radiators, but dust will soar in the air due to flows for sure.
Specifications
Many models of these heating elements have on average the following technical characteristics:
- withstand pressure - up to 106 bar;
- test pressure - 13 bar;
- coolant temperature - up to 110оС.
Properly selected batteries will last a long time and correctly, without forcing the owner to spend money on new radiators soon due to the failure of the old ones.

Advantages
Numerous positive aspects of panel steel radiators are the key to their wide distribution. Among the most significant advantages are the following:
- Multifunctionality - modern panel batteries combine a convector and a radiator. They fully heat the room, while there is no need to purchase additional heating devices.
- Profitability - if we compare a panel radiator and a battery with fins, a smaller volume of coolant circulates inside the first, but it will not be inferior in power
- Functional temperature control - a panel heating radiator can be equipped with a different set of additional devices that allow you to adjust the temperature in automatic or manual modes
High heat transfer rate - a larger area of \u200b\u200bthe panel radiator is in contact with the environment than with finned models. Working on the principle of convection, the efficiency of the units reaches 90%, thanks to which even the largest rooms are quickly heated
A large selection of models and an acceptable, affordable cost for each potential buyer. For steel products, the price is much lower than for copper, aluminum or bimetallic, but higher than for cast iron
One of the positive aspects of panel steel radiators is their original and stylish design. The use of modern equipment in the production process made it possible to give products any shape and diversify style options: from classic to minimalism.
Interior features are a very important selection criterion. By installing a suitable model, it will be possible to recreate a beautiful composition under the window and achieve maximum harmony.
Flaws
All the positive aspects of heating panel radiators discussed above are very significant. However, the products offered by the market have several disadvantages:
- Do not leave the radiator without coolant for a long time, otherwise the inner surface will quickly begin to corrode
It is not recommended to use a coolant with high or low acidity. The optimal indicator is considered to be in the range from 8 to 9.5 pH, otherwise the surface will begin to rust inside
Water hammer adversely affects the reliability of panel batteries. Their installation in a central heating system with increased pressure is undesirable.
Recommendations when choosing a radiator
Recommendations when choosing a radiator
The market for panel heating devices is quite diverse.Manufacturers offer different colors of panels. White radiators are the most common and their prices are significantly lower than for colored ones. If the desired color scheme is still not found, you can install a special decorative grille.
Immediately before purchasing the device, it is necessary to study the attached documentation and product certificates. Compliance with warranty requirements will protect the panel radiator from leaks and further costs for dismantling equipment and installing a new one.
Installation of panel systems is recommended to be carried out in networks with forced circulation of the thermal carrier, completing additionally with more powerful pumping equipment. This will allow more efficient use of the heating device.
It is important during installation to connect the radiator correctly, without confusing the direction of the pipes, install taps, make sure that the pump is powerful enough. In houses with a small number of floors, it is preferable to use heating systems with an operating pressure of 8 bar.
This choice will increase the reliability and efficiency of the system.

In order to avoid damage and loss of presentation, the panels are mounted in their original packaging, after which it is removed.
It is also worth focusing on the gap from the battery to the window sill and the floor, which should be at least 10 centimeters to create conditions for optimal air circulation. Incorrect calculation of the length of the radiator can lead to excessive dryness of the air in the room, which can adversely affect your well-being in the future.

What are the types of panel steel radiators
All types of panel radiators differ in the number of panels, as well as the presence or absence of fins (convectors). All of these affect heat transfer. Convectors are U-shaped steel ribs welded to the panels from the inside. Radiators are produced open and closed with grilles from the sides and from the top. For cleaning, an open radiator is easier, and a closed one looks more aesthetically pleasing. And it has better heat dissipation.
Type 10
Radiators of this type have neither a convector nor a grate, but only one heating panel. The number "1" means that there is only one row of panels, and "0" means that there is no finning. There is no convection - there is no dust, which certainly accompanies it. Therefore, for a hospital or kindergarten, they are a great option. The absence of side walls and grating makes cleaning as simple as possible.
Type 11
Here, too, there is one row of panels, on the back of which there is ribbing. There is no top grille. Thanks to the presence of fins, heating is faster than type 10. Cleaning is more thorough (convection attracts dust).
Type 20
There are two rows of panels, but there is no convector (fins). There is an air outlet. Power is higher than that of single-row models.
Type 21
Again two rows of panels, but with convector fins mounted between the panels. From above the radiator is closed by a casing.
Type 33
Convective ribbing (three rows) is made between three rows of panels. There is a casing. This type of radiator is the most powerful, giving off the most heat and heating up quickly. But it also collects the most dust.

More about the features of panel radiators
Panel heaters in terms of efficiency may be slightly inferior to the best representatives of conventional radiators (for example, bimetallic ones). But it fully pays off with an excellent appearance, and the difference is not so significant.In addition, there are a number of other features, the knowledge of which will definitely not be superfluous.
Advantages and disadvantages of steel panel radiators
Panel radiators have an impressive list of advantages:
- due to the combination of direct heat transfer and convection, the efficiency of the devices exceeds 75%, and the heat is distributed more evenly throughout the room;
- such devices are characterized by a reduced need for a coolant, compared with a heating system that uses cast-iron batteries, the need for water is more than halved;
There are, of course, a couple of disadvantages, you can highlight:
steel is subject to corrosion and, in general, increased requirements are imposed on the quality of the coolant. In particular, it is necessary to maintain acidity at a normal level (pH should not exceed 9.5);
pH should not exceed 9.5
- It is recommended not to leave panel radiators without water for a long time. The fact is that steel will rust when exposed to air;
- such heating devices are suitable only for systems with normal pressure and coolant temperature not higher than 110ᵒС;
- they do not tolerate water hammer.
Installing a panel radiator
The process itself is slightly different from installing a conventional battery.
The instruction consists of the following items:
first you need to check if the window sill is too close to the upper convection grate. If the distance is less than 7 cm, then the radiator will heat the room worse;
Convection will be disturbed when close to the windowsill
- then brackets are placed on the wall, they come with a radiator;
- further, the radiator is placed on brackets fixed in the wall. At the same time, the packaging from the heater has not yet been completely removed, but only in places where the supply and discharge pipelines will be connected;
- if the connection is done by hand, then the next step is to install a Mayevsky crane at the top of the screen and a thermostat (also comes with a radiator);
Installing a thermostat
plugs are installed.
Finally, the packaging from the heating device is removed only after the finishing work in the room is finally completed. Thanks to this, you do not have to clean it from dust, and the risk of scratching the steel surface is lower.
The most common installation errors are:
- deviation from the horizontal during installation. As a result, the thermal power of the device becomes lower than declared by the manufacturer;
- if the gap between the floor and the bottom of the panel radiator is too large, there will be too cool air in the lower part of the room, this will create discomfort;
- it is strictly forbidden to paint the heater with metal-like paints (this will worsen the heat transfer of the device), and the outlet of the device for air release is also quite often painted over.
As for the selection of thermal power, you can simply calculate the volume of the room in cubic meters and multiply by 41. The resulting number will indicate the required power in watts to heat the room. The technical characteristics of panel heating radiators necessarily include this parameter, so it can be taken from the documentation for the heater.
