The people are called radiators heaters, since the principle of operation in the oil battery is the same as that of their relatives, bolted to the wall and connected to the central heating system.Inside the device is a hot fluid (in this case oil, and a household radiator - water) that heats the metal wall in turn transfers heat to the air in the room.The closer to the heater, the warmer, because the air is heated unevenly.To turn this disadvantage into advantage, manufacturers of most of the models equipped with special wheels for easy transport around the apartment.However, cheaper models wheels inhumane with respect to the parquet.
second drawback oil heaters is that they are slow (but true!) Heated air.This problem manufacturers are trying to solve in two ways.First, the device is inserted into a special timer that automatically turns the heater at a certain time, say, an hour before the arrival of the owner.And secondly, is mounted in the housing small fans that accelerate the heat
Nevertheless, this type of heater is the most fireproof.Although them still remain mandatory requirements: their inclusion should not be placed horizontally installed instruments designed for large areas in very small (auxiliary) areas is also not recommended.
name these devices was due to natural air circulation (convection), which is based on their work - hot air rises, gradually filling the space of the room, while the cold goes down - to the heating element, andwithin a circle.
at the bottom of the device are holes - "input", and on top - a lattice through which hot air comes out.Inside the device the air is heated by a hot spiral tube inside (the so-called "Ten" - a tubular electric heater).
One of the main advantages of the device - a nice appearance, which allows it to easily fit into the interior apartments.Moreover, the relatively low temperature of the housing allows to hang the device on the wall, but the higher its location, the lower the efficiency.
It is best to install the convector next to the window, then the warm air wall is a good barrier to winter cold.One of the major drawbacks - slow air heating.
This device could be called high-power hair dryer as well as the principle of his work is the same - the electric coil heats the air and sends it to the fan as far as possible.The main advantage of the device - low price.
In addition, the small size make it easy to carry the device, in other words, to carry heat with them.Some models can be hung on the wall.
Sometimes the fan rotates in the housing of the heater to ensure even heat distribution, and in some models the angle of airflow reaches 1800.
But these heaters have more disadvantages than all the others.Firstly, they have the worst evaluation in terms of fire safety.
Second, the red-hot spiral burn oxygen, dust particles and small insects, causing an unpleasant odor.There is no problem with the fan heaters, which use ceramic heating element, but the price more expensive oil cooler.In addition, any pattern fan heater is another problem - the high level of noise.
infrared heaters (infrared radiators)
They serve as a home mini-sun, just as warm as - sent warm (IR) rays.
distinctive feature is that they do not warm the air, like the rest of heaters, and people and objects that are sent warm light, that is, the energy is not wasted where it is not necessary.
a result of such "targeted" heating, saving up to 40% energy.Such devices are well suited for large rooms, when you need to "warm" only a certain part of the territory.It is also a great way to stay warm in the cold season, staying on the terrace, where there is simply no sense to put the traditional heaters.
"This type of heater does not burn oxygen and prevents the appearance of dampness," - says product manager for network home appliances "SamoByt" Andrei Kravchuk.Add that they are irreplaceable in high spaces - especially in country houses, as almost instantaneously heated floors and other surfaces.And "radiant" heaters - unlike other systems - provide a relatively uniform heating of the height of the room.
install infrared heaters are recommended as high as possible - to increase the coverage area.If the ceiling is suspended, it is possible to hide the wire, to prevent him from hanging on the wall.Perhaps the main drawback of such devices - the high price.
What else to pay attention?
choosing a heater, it is necessary to take into consideration the size of the heated area.As a rule, per 1 m2 requires about 100 watts of power, although much depends on the quality of insulation of the apartment.
heater can provide more comfort, if it is equipped with additional means of control, for example, a sensor for temperature monitoring.This sensor determines when to turn on the device and in which mode to install it.The owner is to supply the desired temperature.Very convenient, if the heater kit includes a remote control.
should also focus on security.Heating devices should be fitted with a security system when faults and dangerous situations.For example, fan heaters incandescent filament cools the supply air.If the product is dropped on the floor and continue to work, spiral heated up to such a degree that just melt the body - this can result in fire.Therefore, the heater should stand sensor, stopping his work rollover.
to country houses, which are often left unattended, it is important that the pipes do not freeze water heaters.Therefore, for such facilities are convenient devices that can continuously maintain the low above-zero temperature (usually around 50C), this feature is sometimes referred to as "anti-freeze"
