The modern heating equipment market is characterized by the ever-increasing popularity of electric heating. This fact cannot be called surprising at all, since not all owners of private and country houses have the opportunity to use gas, but liquid boilers have not been able to gain popularity among consumers.
Why choose electric heating
Solar panels are still not able to get out of the experiment stage. Looking at the situation with heating in apartments, it can be noted that the central system quite often just does not cope with the tasks assigned to it. That is why the purchase of electrical appliances for heating for many families becomes the only right decision so as not to freeze on winter evenings. Those are electric convectors "Nobo". However, here you can encounter certain difficulties, since, considering the assortment of described devices, you can simply get lost without deciding which device is safer, more efficient, practical, and unpretentious in work.
Principle of operation
From the school physics course, you know that heated air tends to rise. Expanding, it acquires a lower density. Cold streams displace heated ones, and the Nobo electric convector works exactly on this principle.
All such devices have a fairly simple design. They are composed of parts, including a heating element and the body itself. To draw in cold air from below, holes are located, the same, but for the exit of heated, are from above. Inside the case, most often in the lower part, there is a heating element. It is designed to process air, which is at a certain point in time between the walls of the structure.
Design Features
The convector "Nobo" distributes air throughout the entire volume of the room, making it completely silent and as even as possible. A number of models are equipped with a fan, which allows to significantly accelerate the process described above. However, if you choose just this kind of device, then you can forget about noiselessness. A certain role in the popularity of convectors is played by the temperature of the walls of the body, which does not rise more than 60 degrees. This fact very favorably distinguishes such devices from oil analogues, which are considered dangerous today in terms of the possibility of burns. This is especially true for animals and children. That is why the owners of those houses where such representatives are present are trying to refuse to purchase convectors.
Characteristics of convectors for a heating element
The convector "Nobo" can have one of three varieties of heating elements. This component may be monolithic, tubular or needle. Tubular heating elements have aluminum fins. Examining the needle elements, you can see a thin plate made of a dielectric, a heating thread made of chrome-nickel is installed on it. It is covered with an insulating varnish during the manufacturing process. Among the positive features of this heater, you can select an almost instant temperature set, however, you need to take into account that this element will cool down as soon. When purchasing Nobo convectors, you should remember that varnished elements do not have any protection against water, so you can not use such devices in wet rooms. As the main advantage of such an aggregate, you can highlight the cost, but we are not talking about durability. In practice, needle-type heating elements are rarely used, but if you still find such an assembly, then it is best to refuse to purchase it.
Characteristics of the tubular heating element
Nobo convectors can also have a tubular heating element, which looks like a metal tube, a nichrome thread is installed in it and is filled with a heat-conducting special backfill. Compared with the above, such a heating element has a less impressive temperature, therefore, it is more durable. If there is a need to use a convector in a room whose conditions are characterized by high humidity, it is best to choose heating elements in a spray-proof design. You should be prepared for the fact that in the process of work the difference in thermal expansion between the tubes and ribs will be accompanied by the appearance of sounds that resemble crackles.
Reviews about appliances with a monolithic heating element
If you decide to purchase a Nobo electric convector, it is best to prefer a device with a monolithic heating element. According to users, such units are completely silent during operation, since the heater body is monolithic, or rather, solid. Devices of this type work with the smallest heat loss, and their effectiveness is at altitude.
Reviews about the power of devices
Looking at the Nobo electric convectors at the point of sale, you will notice that the appliances can have different capacities. If you use the average, then for every 10 square meters 1 kilowatt of power will be needed. At the same time, the height of the ceilings in the room should not exceed 2.7 meters. If this figure turns out to be more impressive, then for an additional 10 centimeters of height, you need to add 10% of the power. All users who have been operating Nobo electric convectors for several years, note: in order to achieve high-quality heating, there are only as many devices that need to be purchased as there are windows in the room. Quite often, we are talking about corner rooms, as well as rooms that are built over a cold basement. Users are advised in this case to purchase a device with a power reserve. This also applies to rooms, which are characterized by an impressive area of glazing.
Reviews of thermostats
Electric convectors "Nobo" may have the ability to maintain the required temperature, for this the device must have a thermostat, and it, in turn, can be controlled by an electronic device or mechanically. Experts advise choosing a mechanical thermostat if you are aiming to save. However, you should be prepared for a number of inconveniences. Consumers mention a rather poor exposure to a certain temperature. Among other things, you will encounter the consumption of more electricity. Buyers note the characteristic clicks that accompany the operation of the device when turning it off and on. If this is not an annoying factor for you, then you should not pay attention to this characteristic. The convector "Nobo", reviews of which it will be interesting to find out before purchasing the device, may also have an electronic thermostat. According to users, it is completely silent, reduces power consumption within the capabilities, and also show the ability to withstand certain temperature values, the error in this case is minimal and can be 1/10 degrees. Such is the Viking-Nobo convector.
