Induction boiler - cost-effective alternative or disappointments?

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.

What is induction boiler

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.

Features induction heating method

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.

Case « for »

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:

  • The complete absence of deposits and other deposits. Due to the magnetic field created by high-frequency vibration, displacing induction energy to the interior surface of the walls of the boiler, where the interaction with the coolant. Thus, the heat transfer rate remains stable, independently from the operation period.
  • The efficiency of the induction of the boiler is stable throughout the operational period and is about 98-99%.
  • Induction pot belongs to the class of energy saving equipment. Cost is ensured high power factor, which is characterized by the frequency of the current used. As a result, operating costs are reduced by 30%.
  • Heating devices induction type are not sensitive to voltage indicator and can fully operate as a network of permanent and AC.
  • The design of the induction of the boiler is a fully sealed enclosure, making it impossible for the probability of any leaks.
  • The device does not provide for moving the boiler and heating elements in contact with the coolant, thus, eliminating the need for maintenance work or in the off-season or during the heating season, which are so expensive for holders of other types of heating devices.
  • Degree   fire   and the induction of electrical equipment is classified as corresponding to the second class. This is a very high figure, allowing the installation of equipment in any room.
  • Operational Opportunities induction boilers producers themselves determined in a period of 25 years and above.
  • As the coolant for induction boilers can be used almost any liquid, that is, not only water but also the oil, or antifreeze, and therefore, operation of induction equipment is possible at any temperature conditions. At the same time,   the liquid does not require preliminary preparation, and its replacement is sufficient to carry out every ten years.
  • The connection with other boilers induction heating systems is not restricted.
  • Absolutely silent operation.
  • A high level of environmental safety.
  • Installation and operation of the induction of the boiler is simple, requires no special skills or conversion.   the existing heating system and provide absolutely. autonomous getting both heat and hot water.

Arguments « against »

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.

What is more important – choice of induction boiler or incorrect installation?

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:

  •   induction type boilers are intended for closed heating systems, equipped with a pump for forced circulation.
  • Grounding – the mandatory installation of the induction phase of the boiler.
  • Attaching to the wall should be strictly vertical.

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.
