How to choose a convector for giving?
To date, the Russian convectors market is incredibly large: it presents both European and Asian manufacturers. With such a variety, a problem appears due to which convector is better to choose for the cottage. The main criteria when choosing this device are: security, efficiency, long service life, as well as its cost. All data Parameters (except for value) are determined by conventional features of convectors.
Main parameters when choosing a convector: safety, environmental friendliness, good operation, low cost.
Electric or gas convector?
It should be understood, what convectors exist today and does it make sense to say that the best is electric, and not any other. Such a device can operate in the following types of substances:
- with water;
- using electrical energy;
- With natural gas.
Due to the cost of natural gas, some consumers believe that the best gas convectors can be purchased in Russia. However, it is not all that it seems to be so simple with this type of equipment. Finding such batteries are quite difficult when electric units are sold everywhere.
What convector is better to choose for giving: Wall-mounted or floor?
Stages of installing a wall convector.
First of all, it is necessary to determine how the electrical convector is planned. Most often, electrical convectors are installed stationary on the wall, under the windows or on a special bracket that comes in the kit. If there is a desire to get a mobile heater, which can be moved around the room, you will need to additionally purchase a set of legs (in most cases for wall convectors sold separately) or buy a convector, which is intended specifically for floor installation. Such batteries that are initially intended for floor installation are equipped with legs-rollers and tipping sensors, which is a rather important factor for exploiting such an instrument. High-quality outdoor electric convectors can be found in the model range of some German manufacturers.
Outdoor electrical convectors are narrow, low (20 cm) and long. Those that are fixed to the walls have a height of about 40-50 cm. There is a difference in the supply of heat. The most effective are the heating devices that are located closer to the floor. This is due to the fact that the warm air will go up. Consequently, wall-mounted equipment is not too profitable to purchase.

In the process of choosing a similar battery, you need to pay attention to the quality of the manufacture of the convector body and the size it has. The appearance and design of the electrical convectors, which are presented on the Russian market, is not different. The case of this device externally is a metal box, which is made of stainless steel, the heating element and thermostat is installed inside it. Its main difference is the height of the convector hull, which to a greater extent determines its convective properties. That is, the speed of the air flow with which the cold air will pass through the heating element. Batteries 0.4-0.6 m high and more have a high air flow rate (thanks to the rift) and faster heating.

In the case of a convector height of 0.2-0.4 m, the heat unit from the heating element will be lower, because the length of such convectors relative to the previous ones is significantly larger. Plinth electrical devices that have a height of 0.15-0.2 m are characterized by low heat flux rates. In such models, the temperature of the heating element is lower than that of higher devices. To preserve performance, they have a large length (up to 2.5 m).
All modern electric convectors are manufactured according to the 2nd class of electrical protection (possess double insulation of the current-handing parts), which makes it possible to install them without performing grounding. The second parameter is the degree of protection. Basically, similar devices have the degree of protection IP 24 (splash-proof version can be installed even in wet rooms), IP 21 (protection against water droplets), IP 20 (design is not protected from moisture).
Heating element of convectors
Electrical convector device.
The most inexpensive convectors, which are presented in the Russian market, are manufactured in Ukraine and are supplied with a needle heater. A similar heating element is able to significantly reduce the maintenance. However, he limits their scope, because it has a lower security class (IP 21).
More modern electrical convectors are supplied with a heating tubular element. The tubular electric heater is the nichrome thread, which is installed in the steel tube with a ceramic, quartz or magnesium filling, on which aluminum fins are fixed. It serves as an effective heat exchanger. The temperature of such heaters is significantly lower than needles, in addition, they are more unpretentious and durable. Convectors with tubular heaters in most cases are performed in splash-proof version (IP24): they can be installed in wet rooms at a distance of at least 60 cm from open water (basin, bathtubs, and so on).
An indicator of the efficiency of the device is a large area of the finish of the heating element. The most optimal parameters are 0.5-0.7 m² / kW. The bigger the area of the heating element, the greater the contact with the air, therefore, is better performance. Not all manufacturers of convectors can boast optimal parameters.
Additional benefits are able to provide convectors who have the ability to switch power. Some of the similar devices are equipped, for example, a heating element with 3 power steps. A similar monolithic heating element with an enlarged area and rigidity makes it possible to maximize the speed of heating the room with full conservation of air ecology.

The presence of the thermostat in the convector
The thermostat device in the convector.
In modern electrical devices, both electromechanical and electronic thermostats are used (which have air temperature sensor). All convectors, regardless of the type of thermostat, are equipped with overheating protection.
Similar devices with mechanical thermostat have the following features:
- affordable price;
- accuracy in measuring air temperature (+ / 0.5-1 ° C);
- When the heating is turned off and on, a characteristic click is distributed;
- High reliability in the process of operation in the conditions of unstable supply voltage (cottage, village, and so on).
In electronic thermostators, a microcontroller thermostat is installed. Its temperature sensors regularly measure the temperature of the cold incoming air and the signal is fed to the control that is capable of maintaining the specified mode with an accuracy of +/- 0.1-0.3 ° C.
Features of similar devices with electronic thermostats:
- higher price;
- completely silent work;
- Good temperature measurement accuracy.
Due to the higher accuracy of temperature measurement, the use of convectors with an electronic regulator is capable of saving electricity in 3-5% compared with electromechanical structures. Models that have an electronic thermostat are most often maintained several modes of operation: economical, comfort, anti-massaging (regularly maintained the temperature + 5-6 ° C) and automatic.
Calculation of the power of this heating device
Table of calculating the power of a similar heating device.
To select the average power of devices for heating residential and service premises, the formula should be used: 1 kW of heat by 10-12 m² of room area (in case the height of the walls will be 2.7 m). If there is a large height of the walls, it is recommended to add 10% of the power for every 10 cm above the specified one. Each window opening should be overlapped with a heat flux. A convector must be installed below it, it is recommended to choose the design of the same length as the windows width. For practical use, the most optimal is the device, which in length is able to completely overlap the window opening. A wide heat flux with optimal speed will be a curtain and effectively hold the uniform balance of the room temperature.
In order to more accurately determine the power of the convector, which is necessary for the heating of the room, the calculation should be carried out in terms of the room, based on the calculation of 35-40 W / m³. It will also be necessary to take into account additional heat loss, which exist in connection with the external walls. If there is an angular room with a cold attic, the basement or it has a large glazing area, it is recommended to select equipment with some power reserve. It will greatly affect the speed of space warming up to the required temperature. If you take a model that has low power, it may happen that the device is simply not able to exit the necessary temperature and will continuously work.

Modern convectors in most cases consume only 30-40% of their total rated power.
In general, each convector model has its advantages and disadvantages. However, the advantages include the following characteristics:
- You should choose those devices that do not burn oxygen.
- You need to give preference to designs that can be used in a completely any room.
- Preferably, you choose batteries that are easy to install and operate.
- Batteries whose Summit are valued more than others.
It is worth noting that the best convector every owner of the apartment or at home chooses for itself.
The choice must be made on the basis of your own capabilities and needs, as well as the place where it is planned to be installed.
What company is best to choose a similar device for heating?
Scheme of the Besmer Converter.
In order to understand which company produces the best convectors, it is necessary to listen to customer reviews. For example, Delonghi most often produces cheap convector equipment that runs from electricity. In general, people's reviews about this manufacturer are good enough, especially if you take into account their democratic cost.
The well-known Gorenje organization produces convectors of different types. However, consumers are most in demand by the heating device of the gas type of this well-known brand. Reviews about the products they produce are in most cases good, but their units have a considerable cost, which must be taken into account when choosing a heating device of an apartment or a country house.
There are manufacturers of convectors who have a fairly large number of bad reviews. Such manufacturers should include Ballu, Selena, Timberk and others. All data firms are Chinese.
What should be aware of the cost of electrical convectors?
In general, similar devices for heating apartments or house are quite convenient and have a large number of advantages in comparison with other heating units. For many consumers, the main advantage is the cost of these structures, because they believe that even the best devices can cost cheaply. To some extent, people who want to save, right. Not always expensive equipment will justify its price.
Situations are often found when low cost is hiding a large number of positive parties. It should be known that the price is not the main criterion for choosing such heating equipment.
