Autonomous heating in a private home is a very complex and important task that can be solved by using electric boilers. Currently, there are not only models with heating elements, but also more economical products - electrode and induction. An induction electric boiler is very popular due to its high efficiency and, accordingly, less energy consumed to heat the room. Let's take a closer look at the capabilities of induction boiler equipment, its advantages and disadvantages.

Induction is physical phenomenon, based on eddy currents, which was discovered and studied by the French physicist J. B. L. Foucault. Induction boiler equipment uses Foucault currents in its operation, operating on the principle of electromagnetic induction.

An alternating voltage is supplied to the coil, an electromagnetic field is formed, which provokes the appearance of eddy currents that heat the metal. Water is heated in a heat exchanger and, circulating through the system, heats the premises in a private house.

Modern heating units based on induction, consist of the following elements:

• heat exchanger or core;
• terminal box;
• inductor;
• control cabinet;
• conductors;
• inlet and outlet pipes.

For ease of operation of the equipment, its design may include additional elements. Essentially, this type of boiler is an inductor, which is placed in a small but very heavy iron alloy housing.

In this case, instead of a core, in some devices a regular metal tube with coolant is mounted. However, the presence of a core increases the heat transfer area.

Such a system has a high degree of reliability, since the induction coil is firmly sealed in a sealed housing without direct contact with the coolant. The occurrence of holes in the coils is almost impossible, since they are not wound too tightly, and in addition they are filled with a special insulating compound.

All this is enclosed in a thick-walled, massive body, which guarantees a long service life. Manufacturers provide a guarantee of 5-10 years, but sellers of boiler equipment claim that an induction electric boiler can last about 30 years without Maintenance.

Design features of two types of boilers

Before purchasing an induction electric boiler for autonomous heating At home, you need to decide which type of equipment is most suitable in your case.

There are two types of electric boilers based on eddy currents used to heat the coolant - SAV and VIN (eddy), which have characteristic differences.

• The SAV electric boiler does not require an inverter to operate. In this case, a voltage from the network of 50 hertz is supplied directly to the winding (coil). As a result, the secondary winding, which is a system metal pipes heat exchanger, is heated by Foucault currents, quickly heating the water. The coolant is forced to move along the heating system circuit using a circulation pump.

Induction boilers type SAV are produced for voltages of 220V and 380V. Equipment with a power of 2.5 kW is capable of heating a room up to 30 m2. You can purchase this electric boiler unit SAV together with automation and control unit for 27,000 - 32,000 rubles.

• Induction electric boilers type VIN (vortex). These are new generation models, the operation of which requires a special inverter that converts the frequency electrical network. Given technical solution makes it possible to make structures smaller and lighter than SAV-type equipment. In this case, the heat exchanger is made of a ferromagnetic alloy, and not only the heat exchanger, but also the body of the unit acts as the magnetic core and secondary winding.

An induction boiler type VIN with a power of 3 kW will easily heat a room with an area of ​​40 m2. The VIN electric boiler, fully equipped with an automation unit, a pump and a circulation pump, costs a little more - from 37,000 to 40,000 rubles.

Advantages of electric induction boilers for heating

Sellers of boiler equipment are full of praise, talking about the exceptional characteristics of induction units. Some of the words are really true, the other part is fiction. For example, consultants state that induction devices save up to 30% electricity compared to electric boilers using heating elements. However, the statement is somewhat exaggerated.

The fact is that both types of boiler equipment consume approximately the same amount of electricity. But induction boilers heat the coolant faster than heating elements, including due to the lower inertia of the system. Therefore, if you turn off the unit in time, when the room is warm enough, then your electricity bills will actually be lower. In this case, it is better to equip the heating system with an automatic control unit.

The efficiency of an induction boiler is indeed very high and is close to ±98%, as with heating elements or electrode devices. However, induction electric boilers for heating a private home they cost more than conventional heating elements. The control unit and automation, special housing alloy and winding increase the cost of the equipment. At the same time, like other technical devices, induction heating boilers have advantages and disadvantages.

We list the main advantages of electric induction boilers:

• high reliability, but it must not be allowed that there is no liquid in the system;
• any type of coolant can be used;
• there is no need to replace any elements of the device;
• scale does not form due to constant high-frequency vibration;
• long boiler service life up to 30-35 years;
• resource savings of up to 25% due to heating speed;
• monolithic ferroalloy body eliminates the possibility of leakage;
• do not require a separate room and ventilation;
• small size - a pipe section from 40 cm to 1 m in length;
• silent during operation;
• does not require servicing;
• the coolant heats up very quickly - in 5-7 minutes;
• autonomous operation system;
• easy installation.

The disadvantages of these units can be called heavy weight with small dimensions - from 30 to 40 kilograms, as well as the high cost of equipment. In addition, for cottages with 2-3 floors, the installation of an additional high-power circulation pump will be required.

Features of installation of induction heaters

Current induction electric boilers for heating should be installed only with a closed circuit with a membrane expansion tank and a circulation pump. Forced circulation needed primarily due to the fact that intense heating and the small volume of the heat exchanger prevent the creation natural circulation the water will boil before the conditions for gravitational circulation are created.

In the event that an induction heating electric boiler is used as a heat generator, then it is necessary to use plastic pipelines in the circuit or to isolate metal pipes from the boiler by installation plastic fittings. The boiler must be provided with mandatory and high-quality grounding.

Installation requirements, as for all electric boilers: from the floor or ceiling surface - 80 cm, from the wall - 30 cm Installation of a safety unit, which includes a pressure gauge, air and safety valves, is mandatory as for all closed heating systems. In private homes, usually used standard system connections.

Installation of induction boilers must be carried out in accordance with the instructions or requirements specified in technical passport. The device must be located strictly in a vertical position, the lower inlet pipe is connected to the return, and the upper, respectively, to the supply. For this, only metal or metal-plastic pipes should be used.

If you decide to install an electric boiler yourself, you must remember about grounding. It is necessary to install a safety control cabinet in the immediate vicinity, and filters and a flow sensor at the inlet.

When purchasing, you need to carefully look at the power of the equipment, which does not decrease during use. The optimal ratio is 60 W per 1 m2. In order to calculate this characteristic, it is necessary to take into account the dimensions of all rooms.

If thermal insulation is not enough, you need to take a more powerful heating boiler. Today's induction units can maintain low temperatures in rarely used areas. Accordingly, a 6 kW electric boiler is quite suitable for a home.

Thus, the simplest and optimal solution for heating is the installation of an electric boiler. They are truly more economical due to lower system inertia, reliability (if you use well-thought-out technology and quality materials) and good operation of the automation, which only includes a system for maintaining the temperature. This equipment is installed as backup in private homes and for heating offices and trade pavilions.

An electric boiler is, without any doubt, an excellent alternative to gas or solid fuel equipment. But it has a significant drawback - high energy consumption. In the process of searching for ways to reduce electricity consumption, the induction boiler was invented.

In fairness, it is worth noting that the principle induction furnace was invented quite a long time ago, back in 1887, and they were used only in industry. The development of the technological process made it possible to create compact models new generation, suitable for household use, for example, heating a private house.

Device and principle of operation

The main element of an induction boiler is a transformer with a toroidal winding. The device of such a boiler itself consists of the following elements:

• The body of the unit, which is made of metal.
• A layer of electrical protection and thermal insulation.
• The core is a ferrimagnetic tube.

The core winding acts as the primary winding, and the secondary winding is the boiler body. Also included in the package:

Not only ordinary water and antifreeze, but also oil can act as a coolant in such a system.

Operating principle

The name induction electric boiler contains the principle of its operation - electromagnetic induction. When voltage is applied, the following processes occur:

• An electromagnetic field is created.
• The core heats up to a temperature of 750 °C.
• The coolant enters through special pipes and, passing through the core, heats up, then transferring the heat to the heating radiators of the house.

This heating method allows you to heat a large volume of coolant in a short period of time. At the same time, the convection currents created make it possible to do without a circulation pump.

Advice! The absence of a circulation pump is justified in small heating systems. When heating with an induction boiler two-story house, its presence is mandatory.

Advantages and disadvantages of induction boilers

Let's first consider positive characteristics induction boilers:

• High and constant efficiency: up to 99%.
• Such a boiler does not require a chimney.
• Lack of mobile and heating elements contributes to high reliability and durability of new generation systems.
• Quiet operation.
• Low inertia of the system allows you to save energy.
• To install an induction boiler, a separate room is not required.
• High-frequency vibration of the core prevents scale formation.
• Easy installation does not require special knowledge or skills.
• High level of fire safety due to the absence of open fire and heating elements.

Like all equipment, an induction heating boiler has not only advantages, but also disadvantages, which include:

• In the first place, of course, is the high cost of such boilers. The more common electric heating element boiler costs 1.5 times less.
• Connection is made only to a closed heating system of the house. At the same time, the pressure in it must be controlled and kept below 0.3 MPa.
• Significant weight with small size. This fact should be taken into account when mounting the boiler on the wall.
• Generation of interference in the entire radio range within a radius of several meters (depending on the boiler power). Such interference is absolutely safe for humans.

Advice! The main advantage of induction-type devices is the fast and economical heating of a large volume of coolant, for which other types of boilers would require much more time. It is this quality that has found its application in induction instantaneous water heaters.

Help in choosing a boiler

Due to the novelty of such equipment, only two brands are represented on the domestic market:

1. VIN - manufacturer LLC " alternative energy" This vortex heater(this is what the abbreviation stands for) consumes converted high-frequency voltage. At the exit from the coil this gives sharp jump EMF tension and increased Foucault surface currents. This allows the body and everyone internal details, which are specially made from a special ferrimagnetic alloy, almost instantly heat up and transmit thermal energy coolant. We can say that all the structural components of the unit act as one heat exchanger, this explains its high efficiency.
2. SAV is produced by JSC NPK INERA. This induction boiler consists of a short-circuited labyrinth of coolant pipes, which acts as a secondary winding. Alternating current, generated in this winding, makes it possible to quickly heat the surface of the heat exchanger. Thanks to the branched labyrinth of pipes in the heat exchanger, the coolant passing through it quickly heats up, which explains the high efficiency of this type of boiler. Thanks to the law of self-induction, the new generation device allows the coil to independently induce the necessary reactive power. This allows the use of this type of induction boilers in power networks with reduced voltage, which gives tangible results when operating in rural areas with weak electrical substations.

All induction electric boilers differ in power and number of connection phases:

• Single-phase: power 2.5–7 kW.
• Three-phase: power 7–60 kW.

In addition to standard automation (automatic circuit breakers), the induction boiler can be equipped with an electronic programmer. This device allows you to set the boiler operating mode for the whole week, and, if necessary, carry out adjustments remotely via a GSM channel.

Boiler power calculation

To calculate the system power as accurately as possible, it is necessary to invite specialists. But you can easily make an approximate calculation, which will be quite sufficient. To do this, for every square meter of heated area there must be 60 W of boiler power.

This power is quite enough, because the efficiency is very high and does not decrease during operation.

Advice! When choosing an induction boiler, it is necessary to clarify the thickness of the core walls. Optimal thickness– 10 mm. This core guarantees long and uninterrupted operation home heating systems.

Installation and connection

Installation of boilers of this type is quite simple, but requires adherence to certain technology:

• Installation is carried out only in a closed heating system.
• It is mandatory to equip such a system with an expanzomat type expansion tank.
• The feasibility of having a circulation pump depends on the system of inclination of the heating pipes of the house. In some cases, subject to correct slope, you can get by with natural circulation.
• The induction boiler must be positioned vertically. In this case, fastening to the wall occurs through special “ears” or ordinary clamps, depending on the model.
• In this case, it is important to maintain a free distance between the boiler and the walls: at least 30 cm on the sides, at least 80 cm at the top and bottom.
• When securing the unit, you should take into account its considerable weight and choose a reliable load-bearing wall for installation.

Connecting the boiler to the heating system

A special feature of the induction boiler is the fact that there is no need to piping metal pipes. You can connect directly with metal-plastic or plastic pipes:

• The pipe located in the upper part of the housing is connected to the supply of hot coolant to the heating system of the house.
• Then the return heating pipe is connected to the pipe located at the bottom of the boiler.
• At a distance of no more than 80 cm from the outlet pipe, it is necessary to install a unit safety group. The set of instruments present in this group is standard for all types of boilers: automatic safety valve, pressure gauge and air vent.
• After the safety group, it is possible, but not necessary, to close the circuit (connecting the hot supply to the return). In some emergency cases, the presence of a small circuit protects the induction electric boiler from overheating.
• In any case, the installation of shut-off valves occurs after the installed safety group.

Next, we move on to installing auxiliary devices on the return pipe. On a small contour or in front shut-off valves The following devices are sequentially mounted on the return line:

1. Expansion tank.
2. Settling filter.
3. Bronze coarse filter.
4. Circulation pump.
5. Flow sensor. The presence of this sensor in the system allows you to control the circulation of the coolant and turn off the boiler if it stops.

More detailed diagram connection is contained in the instructions supplied by the manufacturer, which must be studied before starting installation work.

Electrical connection

Carrying out electrical connections, you must use wires of the cross-section specified in the instructions. Electronic systems controls are connected using special connectors supplied with the equipment.

Advice! An important point installation of the induction apparatus is the ground connection. It must be done with a separate wire (optimally a bus) and connected to the existing grounding of the house.

Induction boiler maintenance

The induction boiler does not require any maintenance as such. The only thing that can be recommended in this matter is to periodically check the reliability of grounding and electrical connections.

In conclusion, it is worth noting that new generation induction boilers are ideal for heating a house where the owners are absent for a long time or are visiting. Cost-effectiveness, autonomy and safety of this type heating equipment fully justify its rather high cost. And if you use antifreeze as a coolant in such a system, then it is definitely not in danger of freezing.

Nowadays, people are accustomed to comfort and coziness. In our country in winter period time, it is possible to ensure warmth in the house only with the help of heating devices. The induction boiler is widely popular among consumers. Its high efficiency results in significant savings on electricity bills. The operation of the boiler is based on electromagnetic induction.

What does an induction electric boiler consist of?

When an alternating voltage is applied to the input of the coil, an alternating electromagnetic field is formed on it. The field itself is closed through the device body and the core. The core itself is located inside the coil and is responsible for inducing low-voltage voltage.

The core is not mandatory element, but thanks to it the heat transfer area increases.

The metal of the core and body is affected by an alternating induced electromagnetic field, which leads to the occurrence of eddy currents. Eddy currents are responsible for heating the metal. The water is charged with heat from the body and core, and then helps distribute thermal energy throughout the room.

• Inductor;
• The core and body acting as heat exchangers;
• Control cabinet equipped with automatic and automated systems;
• Conductors;
• Terminal box;
• Inlet and outlet pipe.

The remaining design details act as decorative elements. It is possible to make induction boilers yourself, then they will have a simpler design. IN homemade boiler the core is made from an ordinary metal tube filled with coolant.

Induction electric boilers and heating elements

The main task of both heating element boilers and induction boilers is the conversion of electrical energy into thermal energy. The devices have the same efficiency, so in this regard they can be called equivalent. Induction boilers are more expensive, but they last for a long period of time.

Practice has shown that after five to seven years of use, heating element boilers are subject to frequent replacement, which leads to significant material costs.

Both devices heat water at almost the same speed, considering the power they consume. An induction boiler differs from a heating element boiler in that it has much large area heat transfer to water. It is worth noting that practically no scale forms in an induction boiler.

Differences between an induction boiler and a heating boiler:

• Heating of the heating element boiler occurs due to the fact that current with increased resistance flows through the conductor of the device. That is why the boiler is heated only to the specified level. temperature regime– up to 750 degrees. The coolant always boils on the surface of the boiler, which inevitably leads to the formation of scale.
• An induction boiler allows the use of different coolants. You can even pour petroleum products into it, but you need to make sure that they do not overheat above 70 degrees.

It is important to know that the heating element is safe to use if its burnout occurs due to depressurization of the housing. If the housing has not been depressurized, the boiler itself becomes dangerous to humans, as it is energized. The heating element boiler differs from the induction boiler in its small dimensions, which can be attributed to its advantages.

Diode heating boiler: advantages

Electric heating boilers are characterized by high efficiency, efficiency and ease of adjustment, which makes them popular among apartment owners and country houses. There is a huge selection of boilers on the market that can be confusing. When purchasing, you should pay attention to performance characteristics boiler, and not on its appearance.

When purchasing a boiler, it is important to pay attention Special attention on how it connects to the network, how its power is regulated, what internal design it has.

Based on the connection method, boilers can be divided into single-phase and two-phase. Boilers with high power are three-phase. The choice of boiler is influenced by the specifics of the electrical network to which it will be connected. The boiler operates on the principle of current flowing through the electrical network, during which the coolant is heated.

Boiler advantages:

• It has an automatic control sensor that regulates the temperature of the coolant.
• High level of efficiency, which is almost 100 percent.
• The heating system starts quickly due to low inertia.
• In the event of voltage fluctuations, the boiler continues to operate, only the power of the heating installation changes.
• The boiler quickly heats the coolant, which contributes to significant energy savings.

If scale or other hard deposits form in the boiler, the device does not stop operating. But it should be noted that the boiler should be cleaned from time to time, as scale reduces its efficiency. If the polarity of the electrodes in the boiler changes, the boiler does not turn off.

Reliable induction boilers SAV: features

To organize efficient water supply, many use SAV induction boilers. They are distinguished by quality and reliability. The boiler control system consists of a start relay, electronic thermostat, coolant temperature sensor, contact group for connecting pumping equipment, air remover.

The coolant in the induction boiler is heated due to the action of the electromagnetic field, which completely eliminates the possibility of damage electric shock. In the manufacturing process of the boiler, the most modern high-tech materials are used. At proper care and use, the boiler will last more than 30 years.

Boiler featuresSAV:

• It is the most economical boiler among all the brands presented.
• Induction heating allows you to use any type of coolant: water, antifreeze, oil.

After purchasing a cat, it is important to carefully study the instructions, which will help ensure proper use and care of the boiler. It is important that a specific boiler model meets all the requirements for its use. You should not install the boiler yourself; for help, it is better to contact a specialist in the installation of such equipment.

Vortex induction boiler working principle

Every inhabitant makes sure that the premises in which he lives have an efficient and reliable system heating. Even at the stage of building construction, you should decide which device will be used to provide the house with heat. Today, the most common types of heating appliances are induction boilers.

An induction boiler can be equipped with a special pump, which will make it possible to provide heating in a house with two or even three floors.

To use an induction boiler in a room with a large area, it is necessary to insulate the walls well so that heat does not escape through them. To purchase an effective model of a vortex induction boiler, you need to know the area of ​​the room, the ventilation of the walls and the level of thermal insulation in the building. It is also important to first determine the installation location and dimensions of the boiler.

What does an induction boiler consist of:

• Outer metal layer;
• Insulating middle layer;
• Inner layer or core.

For the boiler to work, it must be filled with liquid (coolant): water or antifreeze. The liquid moves through the system and enters the device. While in the core, the coolant bursts and releases heat. The advantages of the boiler include the fact that for efficient operation of the device there is no need to install additional generators and reinforce the wiring.

Induction boiler 3 kW: advantages

This type of boiler is used to ensure uninterrupted operation of the heating system. Since the operation of the boiler is not associated with direct heating, it operates much longer than other types of heating devices. Induction heaters are characterized by durability, ease of installation and use, electrical and fire safety, high efficiency and power factor.

An induction boiler of 3 kW assumes the possibility of using any coolant: water, antifreeze, oil, etc.

The warranty period of the device is 2 years, but correct use the boiler will last at least 30 years. Since the operation of the boiler is based on the action of an electromagnetic field, the device is not susceptible to the formation of scale and other heavy formations. Induction boiler can work as additional device if there is another heating system.

Advantages:

• Heating boilers are less practical than induction devices.
• The induction boiler is characterized by silent operation and high fire safety: they can be installed in any convenient location, which may not even be isolated.

But only water should be poured into heating boilers, and it is better that it be distilled. Possibility of choice different types boilers allows you to provide effective work heating systems in any home. Installation of such a boiler does not require the use of additional components.

How an induction boiler works (video)

An induction boiler has many advantages over other types of heating devices. Boilers operate using eddy currents. The discoverer of these currents was Foucault, after whom they are now called. This is absolutely new principle which not everyone uses technical devices. Induction and inductive boilers are a new heating type devices characterized by efficient and long service life.

The operating principle of an induction heating heating boiler is based on the use of eddy currents, discovered and studied by the French physicist Foucault. A modern electric induction boiler used for heating water in heating circuits can be represented as a transformer consisting of an induction coil, a core, a primary and secondary winding, which is inner tube, through which the heated coolant passes.

There are two types of boilers that use eddy currents to heat the coolant. If for the first type a network voltage of 220 V 50 hertz is supplied to the primary winding, then for the other type the voltage is supplied through an inverter that converts the network voltage into currents high frequency, on the order of tens of kilohertz. There is a difference in the material used. For example, if the SAV induction boiler has a heat exchanger from a closed system steel pipes, then for vortex induction boilers a heat exchanger made of ferromagnetic material is used.

Why do you need an inverter?

Many people still remember color tube televisions, which weighed up to 60 kilograms. It was possible to reduce their dimensions and weight thanks to the use of inverters in power supplies. The inverter converted the network voltage with a frequency of 50 hertz into a high frequency voltage of several tens of kilohertz. This voltage was supplied to the transformer, distinctive feature which was a core made of a special ferromagnetic alloy. Physical properties The ferromagnetic material used made it possible to significantly reduce the dimensions and weight of the power transformer. The conversion of the mains voltage of 50 hertz to high frequency is used in vortex induction boilers - these are new generation induction boilers for heating homes.

The voltage is supplied to them from the inverter, the transformer coil is the winding on central pipe made of a ferromagnetic alloy, and the secondary short-circuited winding is the pipe and body of the induction boiler. This technical solution made it possible to make the boiler compact, reliable and economical. But on the other hand, the use of expensive copper for winding and special alloys for heat exchangers, the automation unit and the inverter made the cost of the product high. Therefore, the price for any induction boiler will be significantly higher than for an electric heating element boiler.

Features of installing induction boilers

Modern induction electric boilers for home heating are designed for installation only in closed circuits, with a circulation pump. Forced circulation is necessary, first of all, because the small volume of the heat exchanger and intense heating prevent the creation of natural circulation. The water will boil before the conditions for gravitational circulation are created.

If an induction electric boiler for heating is used as a heat generator, then it is recommended to use plastic pipelines in the circuit or isolate it from the boiler by installing plastic fittings. The boiler requires mandatory and high-quality grounding. Installation requirements are usual for electric boilers: from the floor or ceiling - 0.8 m, from the wall - 0.3 m. Installation of a safety unit, which consists of a pressure gauge, air and safety valves, is required as for any closed system heating.

Advantages of electric induction boilers for heating

The efficiency of an induction boiler is very high and close to 98%, as is the case with heating element boilers or electrode boilers. It is no secret that the price of induction electric boilers for heating a private home is higher than that of conventional heating element boilers. The costs of materials, automation unit and inverter increase the cost of the unit. Like any technical devices Induction heating boilers have advantages and disadvantages.

Advantages of induction boilers:

The disadvantage is considered to be large weight - from 30 to 40 kilograms and the fact that prices for electric boilers for induction are much higher than for heating element boilers.

Main types of induction boilers

Before buying an induction electric heating boiler for your home, you need to choose which type is most suitable.

There are two varieties on sale - induction boilers SAV and vortex boilers (VIN), which have characteristic differences.

Induction heating boilers SAV

Boilers of this type do not require the use of an inverter. A network voltage of 50 hertz is supplied to the winding (inductor). The secondary winding in the form of a system of metal pipes of the heat exchanger is very quickly heated by Foucault currents. The heated coolant moves in the circuit forcibly with the help of. Boilers are produced for voltages of 220V and 380V. A 2.5 kW boiler heats a room up to 30 m2, and you can buy an induction electric heating boiler complete with a control and automation unit for about 30 thousand rubles.

Induction boilers VIN (vortex)

These are new generation induction boilers; their operation requires an inverter - a frequency converter for the electrical network. This technical solution made it possible to make the device compact and lighter than SAV-type boilers. The heat exchanger is made of ferromagnetic material, and the magnetic core and secondary winding are not only the heat exchanger, but also the boiler body.

A VIN type boiler with a power of 3 kW can provide heat to 40 m2.

The kit includes an automation unit, pump and circulation pump, therefore, the highest price for an electric induction heating boiler is about 38 thousand rubles.

Induction boiler - the best heat source

From any point of view, there is nothing simpler, more reliable and better for heating than an electric boiler. Reviews found online about induction boilers for heating a private home highlight only one drawback - the price of electricity, if it were comparable to the price of gas, 99% of the population would forever refuse to use gas boilers. In addition, many are afraid of the possibility of a sudden power outage. But the modern induction electric heating boiler finds its buyer. Electric boilers are installed as a backup in private homes and for heating in offices and retail pavilions.

Electric boilers. An induction boiler is a labyrinth of pipes on which an inductor is mounted. The electromagnetic field of the inductor quickly and efficiently heats the core, which heats the coolant. The core is made of steel up to 7 mm. It can fail, in the worst case, after 40 years. Microvibration inside the induction boiler provides it with 100% protection against scale.

Yes, an induction boiler is more expensive than a heating element, but the colder it is outside, the faster the new induction water heater pays for itself. Even the most reliable German heating element boilers, which are not inferior in price to induction ones, have the same disadvantages: the heating element can be made worse or better, but with constant use it burns out relatively quickly. If the heating element does not burn, scale forms on it, which reduces the flow rate of the coolant - heat transfer drops sharply. Half a millimeter of scale reduces heat transfer by 10 percent. And the further it goes, the worse it gets.

The power of a heating element boiler is reduced by 40% over 4 years of operation. The new generation of induction boilers is energy-saving equipment. Such boilers reduce operating costs by 30 percent or more.

Let's give an example - when heating a room at 200 square meters over 5 years, the loss of efficiency of an induction boiler will be 0%, while a conventional heating element boiler after five years will heat one third of the room at best.

Induction heating boilers differ from others in the absence of heating elements, so the boiler, in principle, cannot fail. The absence of detachable connections completely eliminates system leakage.

What elements does an induction boiler consist of?

1. Circulation pump
2. Heating radiators
3. Induction heater
4. Diaphragm tank
5. Remote Control
6. Ball valve

Induction boilers have another very important feature- they can be used with any liquid coolants, be it water, oil, or antifreeze. And this is crucial in areas with low temperatures. During a power outage, the pipes will not burst. When the power supply is restored, the system will operate as before.

Annual maintenance and preventative repairs of conventional electric boilers by specialists from service organizations is not cheap. Induction electric boilers service not required.

Another advantage of induction electric boilers is that they can be installed in any non-separated room, since this equipment operates silently. It is fireproof.

Let's sum it up. The efficiency of an induction electric boiler is 99%, its operation is silent. It does not require servicing. Installation of the boiler does not require special knowledge and does not require any special modifications existing system heating. The small dimensions of the boiler allow it to be installed in any room. The induction boiler provides complete autonomy in obtaining heat and hot water. By using antifreeze or oil in the system, pipe rupture during an emergency power outage is completely eliminated.

A separate type of VIN is an accumulating induction boiler. It is used in autonomous systems heating, hot water supply and technological processes, in which heating of the coolant is necessary. The storage induction boiler consists of a three-phase primary winding and a short-circuited secondary winding (heat exchanger).
