Heating in every room is one of the major systems that are laid during the design. If it is a private home is likely to be self-heating. In recent years increasingly used induction electric boiler. The great popularity of the device has been achieved thanks to the high efficiency, which makes it possible to consume less energy source than other types of units.
Operating principle
The work is based on the principle of electromagnetic induction. This approach is considered a relatively new in the field of heating. If we talk about the structure of any such boiler is a metal core, a maze made of the form of small tubes. Above it is covered with an inductor, which forms the tension. Such a construction in some way can be called a transformer, wherein coil acts as a primary winding, a core, within which the liquid passes - the secondary.
As a result, under the action of the electromagnetic field is internal heating elements that heat transfer fluid to the heating system.
Thus microvibration core allow the device to protect against sludge, which usually occurs in TENovyh aggregates.
Important! Even a 0.5 mm coating on the heating element capable of reducing the efficiency of 10%.
One of the main differences of induction of boilers from other kinds of devices is the possibility of using any kind of coolant, whether it is water or antifreeze used oil. This can be called one of the major advantages over the electrode assemblies, or heaters, where it is necessary to select a special water.
All manufacturers that offer induction electric boilers, claim that their equipment can save up to 30% of energy consumption. This effect can be achieved due to the fact that the coil acts simultaneously reactive power generator. It is due to this additional power is obtained and the flow rate is reduced.
It should be noted that this effect will be achieved only if the unit and the heating circuit are connected to each other correctly. In addition, the setting must conduct equipment specialists. Otherwise, not only can not achieve the desired results, but even to pay at the time of operation.
Design
In most cases, electrical induction heating boiler consists of elements:
- Coil.
- Core and housing - heat exchangers.
- The control cabinet, which is all the equipment.
- Various conductors.
- Box with terminals.
- Inlet and outlet pipes.
If additional design elements are provided - they are designed for ease of use or even for external aesthetics.
It should also be noted that there is even a simple model in which the core protrudes from the metal tube. Typically, this device, made with his own hands.
dignity
Induction electric heating boiler has a mass of the positive aspects, including:
- protection from scale, which allows to deal with a reduction in the efficiency and significantly increases the service life;
- the use of different heat transfer fluids which possess different characteristics;
- You do not need time to change the heating elements of the time;
- long service life, which is limited by the quality of seams on the machine or an induction coil;
- usually provided releasable connections, which eliminates the possibility of leakage in use;
- it is not necessary every year to carry out diagnostics and maintenance;
- quiet operation, enabling installation in any part of the premises;
- small size - no need to create a separate room;
- no harmful substance for the human body or the environment;
- no need to install additional ventilation or chimney;
- heating of the liquid takes place in 5 minutes;
- when compared with induction heating boilers of electric heaters - the former have an economical energy consumption.
disadvantages
Like any other system, they also have their drawbacks:
- used exclusively in closed systems with positive pressure (some manufacturers offer a pump with automatic unit);
- high weight - average 35 kg;
- complete dependence on electricity;
- price is higher than models with heating elements.
Kinds
Such boilers for heating homes today are of two types: SAV and VIN. Each of them has its own characteristics.
SAV
On the inductor in such units electricity is supplied at a frequency of 50 Hz. The secondary winding acts as a closed tube, which is located inside the coolant. The latter also is a heat exchanger, in which heating is carried fluid heating system. induction process can quickly raise the temperature of the labyrinth tube, which considerably increases the productivity of the machine. Such devices connected to the networks 220 and 380 - all depending on the power.
The boiler of this type is 2.5 kW able to allocate energy 2100 kcal / h, which makes it possible to heat the room comfortable, the area up to 30 square meters. m. The average price of the market, together with automatic hovering around $ 500.
WINES
Electric boilers VIN or vortex induction precursors differ from that supplied to the primary winding of the current transformer is first passed. This process allows you to make it a high frequency. Due to such a mechanism can achieve higher overall electromagnetic field voltage. And this in turn makes it possible to strengthen the eddy currents.
The body and the inside of the unit created specifically made of a ferromagnetic alloy. As a result, certain processes there is a strong heating. In connection with this heat exchanger in the boiler is not only the design of the tubes, but also the individual components of the housing.
Such units with a capacity of 3 kW is isolated to 2500 kcal / h. This makes it possible to heat the premises with an area up to 40 square meters. m. In most cases, such equipment sold with automatic, valves and pump. Their average market price is about 580 dollars.
As can be seen, boilers, which are based on the phenomenon of electromagnetic induction, has all the advantages of other electrical equipment. In addition, they also have an additional. If properly set up and configure the system, it can save up to 30% energy source compared with the same TENovye.
