Heating /
The search for additional sources of heat for a long time remained one of the most pressing problems in home heating. The use of natural resources as energy sources is not only always available, but are often not economically profitable. However, with the creation of energy-efficient induction heating boilers consumers have a chance to take a new look at the possibility of heating equipment, both in functional and in an operational sense.
As the name implies, the work of the induction of the boiler is based on the principle of electromagnetic induction. The role of the generator performs the inductance of the coil, and the intensity of heat transfer is enhanced through a maze of pipes and multi-layer construction of the boiler.
The outer part of the induction equipment is made of metal casing, whose walls are lined inside with two layers: thermal insulation and electrically. Inside the housing is in the form of two core inserted into each other, ferromagnetic steel pipes with very thick walls. The space between the tubes is filled with water flowing through the pipe at the bottom of the boiler.
The inner tube is provided with a toroidal coil, which generates a high-frequency magnetic field under the influence of an electric current. The eddy currents resulting from the growth of resistance, contribute to heating the surface of the casing pipe and washed by its waters. Thus, the outer pipe acts as a heating element and water – coolant.
The first induction type heaters came on the market heating equipment at the end of the last century. Although since it was still not much time, the popularity of induction boilers steadily gaining momentum, significantly surpassing the alternative electric heating.
This love of consumers induction heaters are required, above all, a special effect, which allows the use of magnetic induction. And not only in the almost instantaneous heating of the coolant, but also high efficiency induction boilers. Indeed, thanks to the extra power generated in the resonant circuit, the amount of energy consumed is reduced several times as compared with other modern methods of heating premises.
Therefore, induction heaters are recommended for use in dwellings and buildings, industrial and administrative facilities on the territory of objects with high requirements for environmental safety, as well as in technological systems, including the use of an intermediate heat transfer fluid.
Given that the modern market of heating equipment offers an incredible number of species and types of devices for heating, will not be superfluous to analyze the characteristics of induction of boilers, from a practical, that is, the consumer point of view. Let us first consider the arguments in favor of the acquisition and use of induction units. And they, as it turned out, a lot of:
Despite the uniqueness and versatility, it would be wrong to consider induction boilers perfect equipment, – some shortcomings still exist, and they have.
One of the main disadvantages of induction boilers is their considerable weight and large size. Indeed, many different models of devices ranges from 20 to 80 kg.
On the other hand, after installation, it is unlikely someone will excite consumers of its mass – operation of induction boilers does not require them to move. Moreover, the use of modern technologies will lead to the release of models of compact size, providing the possibility of mounting on the wall, and thus contributing to significant savings in installation space.
Second, and quite a serious lack of induction of boilers, – high price. It is a fact – among alternative current devices electric heating, induction equipment is in the list of most expensive.
However, there is another side to the coin. While the purchase is fraught with induction boiler let high, but edinorazovymfinansovym investment, the acquisition of certain other types of heating devices requires a lot of effort and expenses. For example, such as obtaining the relevant permits for installation and laying of communications, as well as installation and annual sales service.
Furthermore, the list of disadvantages induction boilers including their ability to create a wave interference. Although the range of such interference is only a few meters, but this factor may be important to preserve the well-being of people who are inclined to perceive magnetic waves. In such cases, the problem is solved if the induction equipment installed in a separate room.
There are two types of boilers induction type: single-phase power which 2.5-7 kW and three-phase power which is from 7 to 60 kW. The index required capacity is determined by the principle: for every square meter of heated area should account for sixty-watt boiler. This option must be considered when choosing an induction equipment.
Along with this, it is important to know some rules for its installation:
Due to the induction heater, heating any premises was a simple, affordable and reliable. And their minor shortcomings are more than compensated for by high consumer characteristics: efficiency, ease of maintenance, maximum safety and minimal material costs.
