Induction heating boiler: the principle of operation and the device with your own hands. Diy induction heating boiler: induction boiler heating circuit for a private house Induction boiler connection diagram

Boilers of various types are used in modern hot water heating systems. If we consider electric water boilers, then according to the method of heating the coolant, they are divided into three main categories:

Electric water boilers in the heating system

Classification

1. Heating elements. In such boilers, water or other liquid is heated using TENs - special heating elements.
2. Electrode. The heating agent is heated using electrodes. Since water is a conductor of electricity, an electric potential is created in the boiler chamber between two electrodes, and as a result, water is heated.
3. Induction. The design of this boiler for heating a private house resembles a transformer, in which a metal core, which is in a magnetic field, plays the role of a heater. This is a relatively new type of electric boilers, which are becoming more and more popular every day.

Industrial induction boiler

Dignity

Each type of electric boiler has its own advantages and disadvantages. If we consider induction boilers, then here we can highlight the following advantages:

1. Water in such boilers heats up much faster than other boilers. This is due to the fact that no time is wasted on heating the heating elements themselves or the electrodes.
2. Such boilers have almost the same efficiency as a transformer: they are many times greater than boilers of other types. Moreover, it does not change throughout the entire service life of the product.
3. There is a slight vibration during the operation of the heater, therefore less scale is formed in such boilers.
4. The service life of such a factory-made device is approximately 20-30 years, since it has very few parts that can break.

Flaws

Two of the disadvantages of this device can be distinguished: cost - such devices are currently quite expensive, but it can be assumed that in the future the price will fall. And good home master will be able to make such a device on its own, reducing the cost of the finished product several times, a magnetic field is formed near such a boiler, the effect of this field on a person is not fully understood, therefore it is not recommended to install it in residential premises.

Having considered all the good and bad sides of the operation of this type of boilers, you can decide to install such a device in the heating system of a private house. If the head is in place, and you don't want to spend extra money on the purchase, then you can make it yourself.

DIY making

Before making such a device, you must first understand how it works. Actually induction furnaces exist for a long time and until recently were used in production for melting metals in a magnetic field. This furnace works like a transformer: a high frequency current, of the order of 1 MHz, is supplied to the primary winding. The second is short-circuited, the role of the core is played by a piece of metal to be melted. That is, if a dielectric, for example, plastic, enters a magnetic field, then it does not affect it in any way, the metal will immediately melt. This is how such furnaces differ from heating elements, in which everything melts.

The principle of operation of such a boiler is shown in the figure below. The arrows show the movement of magnetic fields inside and outside the winding.

The principle of operation of an induction boiler

In the manufacture of an induction boiler, you can go in two ways: the core is a piece of pipeline, in the middle of which there is a metal core made of pieces of wire. A radial or toroidal winding is wound around the pipeline, through which an alternating current of high frequency is passed; the boiler is a container for water, which is heated by an industrial induction cooker.

To manufacture a device of the first type, you need to take a piece of pipe with a diameter of 50 mm, in which an adapter is soldered on one side, and inside the passage is closed with a pre-cut circle from a metal mesh. Then, pieces of 7 cm long are cut from a metal wire with a diameter of 5-8 mm. These segments are laid in the pipe and covered with a net so that they do not get into the heating system. On the other hand, an adapter is soldered to the pipeline for tapping the boiler into the heating system. 90 turns of copper wire with a diameter of 1.5-1.7 mm are wound on this pipe. In this case, it is necessary to ensure that the turns are located evenly and as tightly as possible to each other.

For winding, you need to take a new wire, since the product may not last long with the old wire.

The figure shows a variant of such a boiler.

Plastic pipe boiler

To power the boiler, you can use either an induction cooker or a welding inverter. When using a tile, the winding is connected in place of the output coil of the device. It is better to use a welding inverter with a continuously variable current control. If a welding inverter is used, the output current is selected empirically, so that the winding does not overheat, and the boiler works well.

It is possible to connect a boiler of this type only if there is water in the system, since without a coolant such a boiler will simply melt.

For the manufacture of a boiler of a different type, first of all, it is necessary to purchase an induction cooker of the required power. After that, you can start making the boiler tank. The tank is made in the size of 600 × 500 × 50 mm. For this, it is taken square tube 5cm wide. 12 pieces of 500 mm length are cut from it. 10 pieces are welded together with the walls to get a comb with dimensions of 500 × 500 × 50 mm. In the two remaining pieces, one wall is cut out and welded with their cut side to the outlets of the comb pipes. After that, four 5 × 5 cm squares are brewed, and the tank is ready. On both sides, the inlet and outlet pipes are welded diagonally. A tile can be screwed to the back wall of the resulting container so that the control panel protrudes from the tank.

Before connecting the hotplate and connecting the boiler to the heating system, the welded structure must be checked for leaks. To do this, one outlet must be drowned, and the other must be supplied with water under pressure. If there are no leaks at a pressure of 5 atmospheres, then you can work further, if there is, you need to digest.

The figure below shows one of the variants of such a boiler, where the welded structure is visible in the foreground, from behind which the control panel of the induction furnace is peeping out.

Induction furnace boiler

When operating devices such as an induction boiler, you need to know the following:

1. Such boilers should be used in forced-circulation hot water heating systems, since water must constantly circulate in the boiler.
2. It is better to install the boiler in non-residential premises, since a magnetic field forms around it, which can adversely affect the human body.
3. There must be a relief valve in the heating system, because if the pump fails, the core on the boiler will simply rupture.
4. The distance from the floor and ceiling of the house to the boiler must be at least 80cm, and from nearby objects - 30cm.
5. The welding inverter must be grounded to avoid electric shock.
6. An RCD must be present in the inverter connection system, which will prevent accidents when working with the boiler.

Do not install the boiler in a residential area, as it is an unsafe device for humans, as it emits a harmful magnetic field, and is also an electrical and explosive device.

You can learn about the features of the installation and operation of an induction heating boiler from the video below.

In conclusion, we can say that boilers of this type are still an innovation in heating systems, but they have already proven themselves quite well in the heating equipment market. In terms of efficiency, they are inferior only to infrared heaters. However, unlike infrared heaters, induction boilers can be made independently, which makes them more affordable for a wide range of consumers. Moreover, if there is a choice between heating elements and induction, then, most likely, it is necessary to make a choice in favor of the latter, in view of their obvious advantages. In terms of reliability, energy efficiency, efficiency, they are not inferior to any heating element boiler.

In contact with

At the moment, there are many methods that allow you to solve the heating problem with minimal cost. And among them, induction boilers should be called a rather attractive option. Today you can buy them, as well as do it yourself. Moreover, the second option is more preferable, since it allows the owner to save a lot.

The fact is that during the operation of such a device, the induction energy of electricity is consumed most rationally. At the same time, this device has such advantages as safety and environmental friendliness, since during its use, no substances that can negatively affect health and the environment are released into the atmosphere.

How it works?

According to its design, a do-it-yourself induction boiler made kind of electric inductor, the design of which is represented by primary and secondary short-circuited windings. The task of the internal winding is to create eddy currents from the incoming electricity. This leads to the appearance of an electromagnetic field in it, which goes to the secondary short-circuited loop, which plays the role of a body and at the same time a heating element. As for the secondary winding, it is necessary to transfer the received energy to the coolant. As the latter, it is permissible to use oil, antifreeze and purified water.

If we describe briefly how exactly an induction heating boiler works, then the latter must ensure the flow of water into the heating device.

After that, the electricity goes to the inner winding... When a voltage is created, the vortex flows are transferred to the secondary winding, providing heating of the core. When the entire surface reaches the required temperature, the coolant begins to heat by distributing heat.

Getting started

Considering that the induction boiler used for heating does not contain complex elements, to make it with your own hands is within the power of any person who at least once had to work with wire cutters and welding inverter.

The result of the work performed:

After completing all the above operations, we will have a device that will only have to be connected to heating system... To carry out the installation on your own, you will need to cut a piece of pipe, and then insert an induction boiler there. After that, the coil is connected to the inverter, and finally, water is introduced into the system. Keep in mind that the system must contain a coolant for the device to function.

If the boiler starts to work in the absence of water or other coolant, it can end up extremely deplorable. Due to lack of cooling the plastic pipe will melt, as a result of which you have to redo everything. In addition, you need to pay attention to the grounding of the heating device that you made with your own hands.

Do-it-yourself vortex induction boiler

What is necessary?

This will require a three-phase transformer and a welding machine, which you must know how to use. An important advantage of a vortex induction boiler is that its design does not contain standard units that are unable to cope with intensive operation. Therefore, there is less chance that the boiler will fail.

The same can be noted with regard to detachable connections, which are not used in this device. This completely eliminates the risk of leakage. Other advantages of a vortex induction boiler include lack of strong noise during work. Therefore, in terms of choosing a place for its installation, there are no restrictions.

How it works?

The design of a vortex induction boiler is represented by a pair of pipes. To combine them into a single product, a welding machine is used. The result should be a circle. A similar circle will be used as a core and at the same time a heating element. When creating a winding, it is placed on a plastic case. Such a solution will help increase the efficiency and productivity of the instrument. It is advisable to equip the device with a durable insulating cover that protects against heat loss and current leakage. When using such a coolant, the latter interacts with the said winding, which must be created according to the scheme used in simple induction installations.

How to install and install?

Do not rush to make a vortex induction boiler with your own hands. Before you start implementing this concept, you should understand a number of important points:

Is it worth the risk?

Naturally, the process of making an induction heating boiler with your own hands fraught with difficulties... Therefore, you should immediately prepare for the fact that it will take some time and require enough strength on your part. However, you can still make significant savings. The point is that your expenses for purchasing materials will be small. Everything that you may need during work, you can easily find in the nearest hardware store. The most important thing here is that, subject to all the nuances of manufacturing this device, it will be able to successfully cope with the functions assigned to it for 30 years.

So that the end result does not disappoint you, perform all operations in a strictly defined sequence and do not rush. It is enough to try it once, and later you will cease to believe that such work as making an induction boiler for heating with your own hands is beyond the power of an ordinary owner.

Conclusion

Despite the fact that today many methods are available, which are able to effectively solve the problem of heating a private house, induction heating boilers can be one of these options. Moreover, there is no particular need to contact specialists, since anyone can do this heater do it yourself. However, don't expect it to be easy. Have to stock up necessary materials and tools. Also, advice from other craftsmen who have experience in creating this kind of devices will not hurt here.

Particular attention should be paid to competent installation induction heating boiler. Indeed, otherwise you will create a dangerous situation for yourself and the people living in the house where this device is installed. In addition, mistakes in choosing a place for such a heating boiler will not allow it to demonstrate maximum efficiency. Do not be afraid that you will not be able to make the induction heating boiler correctly the first time.

If you have any questions, do not be afraid to address them to more experienced colleagues, because today the Internet is ready to help everyone. And there is no need to be afraid of this task, because the advantages inherent in this device will fully recoup the time and money spent on its manufacture and installation. And homemade induction boiler heating will help you save money during its operation.

Today it is hard to believe that heating can be economical. We either pay for electricity and gas, or we burn huge amounts of natural raw materials. But there is a design that can save our wallet - an induction heating boiler, which will also be cheaper to make with your own hands.

Is it difficult to understand how it works?

For the operation of such a boiler, electricity is still needed, but the bill will no longer be so frightening. The main advantage of such heaters is in their design. They convert electricity into heat very advantageously (the working environment takes up almost 97%). This allows for fast heating at minimal cost. Working environment or the coolant for an induction boiler is most often untreated water, which heats up and spreads through the heating system of the house. But for this purpose, oil or antifreeze is quite suitable.

The power conversion system consists of two windings. The first takes current from the network, creates eddy currents that cause an electromagnetic field. It is directed to the outer winding, which is also the boiler body. It is here that the heating agent, which goes through the pipes, is heated.

The induction unit must have an inlet cold water and hot outlet. Usually the input is welded to the bottom of the case, and the output is welded on top. The carrier is fed inward, flows around the body, heats up due to good thermal conductivity and leaves through the upper opening into the heating system. The main difficulty in creating your own boiler is to correctly position the outer winding and core so that the vortex flows and the generated field effectively heat the boiler. For this, it is important to disassemble the above diagram, which is understandable for a person with average knowledge of physics.

In addition to the beneficial conversion of electricity, such boilers are also less likely to break down, because there is no individual static heating element. Scale also does not settle on the case, because the winding system is constantly in a state of slight vibration. The induction boiler operates quietly and does not produce harmful emissions. Also, leaks of such a system are unlikely, because the number of welds is minimal, or even none at all. The main disadvantage of an induction heater will be its price, so there are more and more homemade schemes, we will consider one of them. Also, it cannot be located near the permanent residence of people, because this is a source of EMP, which means that a separate room in the far corner of the house will be required.

We collect the simplest induction boiler

The most straightforward heater will simply replace part of the pipe in the heating system. How realistic it is to assemble such an induction boiler with your own hands, evaluate according to these instructions.

How to assemble an induction boiler with your own hands - a step by step diagram

Step 1: Choosing an energy converter

Electricity will be greeted at the entrance. Only very advanced users can make it on their own, since we called this scheme the simplest one, we assume that you simply purchase it in the appropriate store. Which one of the proposed ones to take there? It depends on the wattage that you expect from the future induction heater. On average, a 15 A high-frequency welding inverter is suitable for a small house. It is desirable to have a smooth current change function.

Step 2: Heater body

We will not tinker with the complicated inside of our boiler, let us run water through a heated steel wire. To do this, we take rolled products with a diameter of at least 7 mm. Cut into pieces 5 cm long. The quantity is determined by the size of the case, where we will fill them. We will make it from a plastic pipe with thick walls, we will wind an induction coil on it in the future. Naturally, the plastic must be heat-resistant. It is undesirable for the pipe diameter to exceed 50 mm. We will find out its length after we wind the coil, so take it with a margin.

Step 3: induction coil and connection

To create a coil you need copper wire, it evenly wraps around our plastic pipe. It is enough to make 90-100 turns. It is important to maintain the same indentation between them. When you get the desired result, step back 10 cm from the outermost turns and cut the pipe.

Step 4: adapters

Now we will organize the supply and output of the coolant. To do this, you need to attach the appropriate adapters. We place a metal mesh on both sides of the pipe, it will prevent pieces of wire from spilling out. From the bottom we attach an inlet adapter through which water will flow. Then we fill the case with wire tightly and completely and close it on top with an outlet adapter. It is advisable to equip the inlet and outlet with a ball valve in case you decide to dismantle the boiler, then there will be no need to drain the water from the pipeline.

Step 5: Connect

The ends of the coil are brought out to the inverter, but it is still too early to connect. First, the resulting unit must be embedded in the heating system. To do this, we saw off in a suitable place a part of the pipeline of such a size so that the homemade boiler located instead of it becomes without gaps. We fix the inlet and outlet through the adapters. Now you can connect the coil to the AC inverter. It remains to put water into the system and turn on our boiler.

What conditions are required for the safe operation of the boiler?

It turned out to be not so difficult to assemble an induction boiler on our own, but there are several circumstances without which we cannot achieve its correct operation. Such a heating unit will not function if there is no forced circulation of the coolant in your heating system.... That is, it should be a closed network with a pump, which will drive water along the circuit. Also, you must be able to ground the inverter, otherwise fire safety will be in question. This unit must be connected to the network through the device protective shutdown(RCD).

It is imperative that there is water in the system. It is strictly forbidden to turn on the boiler without it. After all, the coil is wound on plastic pipe which is unable to withstand the temperature of a hot metal wire. Therefore, the body will simply melt, and further consequences are unpredictable.

There are no special requirements for the material itself, where the boiler crashes. It can be both plastic and metal. The main thing is that it is a rigid structure, and not dangling hoses. Coil location for reasons fire safety should be 30 cm from walls and 80 cm from floor and ceiling. If there should be some other appliances or furniture nearby, then it is also advisable to keep the distance to them about 30 cm.

It also does not hurt to install an automatic valve with a pressure gauge at the outlet of the boiler so that, if necessary, it will release the increasing pressure, from which our body can crack. This will be needed if the forced circulation device needs to be turned off or the pump simply suddenly breaks down. If you like this idea, then the adapter at the outlet of the boiler should be triple (two inlets for the possibility of draining water in different directions, the third for the valve). The body of the induction heater can be covered with insulating material. This will reduce heat loss and exclude the possibility of touching the coil inadvertently, which will shock you. We would make this recommendation a mandatory condition.

Induction heating boilers appeared on the market not so long ago, but have already become a serious competitor to classical equipment on heating elements. Devices of these types have the same dimensions and do not differ in terms of power consumption. However, inverter equipment has a number of advantages, for example, they warm up the heating system faster. Applying the existing knowledge, you can create an induction heating boiler with your own hands.

Principle of operation

At the heart of all induction-type devices is the ability of materials that conduct electric current to heat up under the influence of eddy currents, which are created using electromagnetic induction. As a source of induction, an alternating electric current of high frequency is used, passing through the first winding of the heating device.

The secondary short-circuited winding is presented heating element located inside the coil. Eddy currents can also occur at a standard mains frequency of 50 Hz. However, in such a situation, the heating device will not be able to function with maximum efficiency, and vibration and noise will be observed during its operation. Thus, the frequency must be raised to at least 10 kHz.

Part 2. Do-it-yourself induction boiler - it's easy. Choice induction hob... Refinement.

Unit device

The heating inverter boiler consists of a heat exchanger, which acts as a core, on which a toroidal winding is wound, connected to a frequency converter. When an electric current flows through the winding, an alternating magnetic field appears, causing eddy currents to appear in the heat exchanger.

The frequency required for the operation of the heating unit is set using signals from the control unit to the frequency converter. Everything industrial boilers of this type are equipped modern systems automation to provide optimal temperature coolant, and also turn off the unit in case of emergency.

The heating medium passes through the heat exchanger and is heated by eddy currents. Since the temperature indicators of the liquid at the inlet and outlet are different, continuous circulation of water in the heating circuit is possible even without using pumping equipment... Oil, antifreeze, antifreeze and water can be used as a carrier.

Special attention should be paid to the fact that the quality of the liquid does not matter- the system is in a state of constant vibration, which is not felt by humans, and this prevents the formation of scale on the pipes. The outer shell of the boiler is metal structure equipped with thermal and electrical insulation systems. Below is a diagram induction heating do it yourself, which can be implemented quite easily.

Among the advantages of induction-type heating devices, it is worth noting the following:

However, the inverter unit also has several disadvantages. The most significant of these is cost. That is why many home craftsmen decide to make an induction boiler with their own hands. Drawings of this device can be developed independently, but you can use ready-made. Wherein homemade construction practically will not be inferior to industrial models in terms of work efficiency.

Part 4. Do-it-yourself induction boiler - it's simple. Testing in the hot water heating system.

There are several design options for this type of unit. However, not all do-it-yourself induction heating boilers are easy to manufacture. There are two constructs to look out for.

From inverter welding machine

When creating induction boilers with your own hands, the most difficult thing is to assemble a high frequency converter. To simplify the task, you can use a welding inverter that outputs a signal with a frequency of at least 20 kHz. You will also need the following materials for work.:

• Copper conductor with enamel insulating layer 1-1.5 mm in diameter.
• Insulated wire and terminals for connecting the coil to the inverter.
• Sections of stainless steel wire about 5 cm long and 3-5 mm in diameter.
• Water supply polyethylene pipe 100 cm long and 50 mm in diameter.
• Stainless steel fine mesh.
• Pipe adapters.
• T-piece for connecting the safety valve.
• Two ball valves.
• Textolite strips and epoxy glue.

A plastic or metal switch cabinet can be used as a housing. First, on a polypropylene pipe, stepping back 80-100 mm from its ends, it is necessary to strengthen 4 textolite strips with a width of 8-10 mm. Then from 50 to 100 turns of wire, covered with an enamel protective layer, are wound on them. The distance between the turns should be 0.3-0.6 mm.

The exact number of turns is influenced by the diameter of the conductor, its resistivity and the output parameters of the inverter used. If the unit will be mounted in a residential area, it is better to make a toroidal winding in order to reduce the strength of the external electromagnetic field.

Diy induction boiler part 1

A stainless steel mesh should be inserted into one end of the pipe, and then tightly packed with pieces of stainless steel wire. After that, the second end of the pipe must also be closed with a mesh. Adapters are mounted on both sides polyethylene pipe, after which ball valves are installed on them. The relief valve must be installed on the side of the upper outlet adapter.

It is also necessary to coat the winding with epoxy. For the manufacture of the composition, you need to take a little more hardener than recommended in the instructions - by about 10-15%. After that, it remains to connect the winding to the inverter and install the heat exchanger in the case. It is important to remember that induction heating units cannot be started up without heating medium. Before testing the system for performance, it must be filled with water.

From an induction hob

Two design options are possible here. To implement the first solution, you have to disassemble the stove and use copper core its heating element for making the coil. The tile control unit can be used to power the winding. However, this method has several significant disadvantages:

• It is necessary to re-calculate the inductance index of the homemade coil.
• Many plate models are equipped with a system automatic shutdown after a certain period of time since the start of work.
• Induction cookers most often have a power of no more than 2.5 kW, which makes them suitable only for the manufacture of a heating unit of small power.

Which heating boiler is better? An induction electric boiler for 2 kW versus a heating element for 2 kW.

A simpler and more efficient design does not require preliminary disassembly of the slab. It is enough to install a sealed stainless steel tank on this device. This tank will act as a boiler for the heating system. To get started homemade unit it remains to connect the tank to the heating system.

If the home craftsman has good knowledge of electronics, then after finalizing the stove circuit, you can make a good induction boiler. However, most craftsmen choose simpler ways to solve the problem. Whatever design is used as a result, it will save on the purchase of factory equipment.

The energy resources that are usually used for heating private houses are constantly increasing in price. Heating suburban housing without additional spending will help heating. It is this method for heating generating heat that will allow you to achieve the maximum result for little money.

The device does not have to be purchased. Any householder can make an induction boiler himself. Moreover, this type of housing heating can be used as in large country houses and in small country houses... The owner of any property will be satisfied with the economic result.

Principle of operation

The principle of operation of high-frequency induction boilers allows you to leave the old room heating system unchanged. This will delight those who like to save money. After all, redo the heating in big house will definitely be a pretty penny. And it took a long time. Do-it-yourself installation of an induction heating boiler does not take much time or money. It is available even to an inexperienced master.

Induction boiler

An induction heat generator is a transformer that uses the principle of primary and secondary winding. This is how the simplest operating principle can be described. The primary coil of the boiler converts electric field... The secondary winding directs heat to water, oil, antifreeze, whatever.

Understand schematic diagram an induction boiler and even a novice master is able to bring it to life. There are layers under the body thermal insulation material, electrical insulation, double-walled core as well as external circuit. The result of this design is the almost complete absence of heat loss during transfer to the coolant.

Photo of the induction boiler circuit

What makes the high-frequency apparatus so highly efficient? The secret is that the coolant in a shorter period than in conventional systems - twice as fast - has time to heat up twice. All this is due low level inertia. The financial benefit from this design is obvious. There is another plus thanks to magnetic field remain clean and free of limescale.

Other benefits of induction heating become apparent with use. The term of use of the equipment is not limited in any way. The resulting structure does not need to be maintained in any way, even cleaned. Wipe the dust off the surface as much as possible.

Induction boiler device

The most simple form induction heating boiler can be successfully implemented in rooms of different sizes.

To create a cheap induction-type heating system in your home is a simple matter, anyone can do it. You do not need to receive special education. You don't need to study the theory of heating either. It is enough to have at hand necessary tools and raw materials to bring the idea to life.

With your own hands it is quite real. What is needed for this? Welding inverter - for quick and easy body assembly and wiring. Next, you need to select materials that will be heated using an electromagnetic field. Experience has shown that steel wire is the most effective and inexpensive option. Diameter no more than 7 mm. It must be cut into pieces no longer than 5 cm.

As a body of an induction electric boiler, it is easiest to use an ordinary one, the inner diameter of which also does not exceed 5 cm. It is necessary to place the base of the induction coil in it. For these purposes, it is better to choose a pipe with thick walls. In this part, the device will heat up. This will become a section of a pipeline with a coolant.

Connecting an induction boiler to the heating system is one of the key steps. For this, special adapters are used that connect the heating pipes to the mechanism. The heat carrier through the adapter will enter the induction boiler, heat up there, then heat the entire heating system. Thus, the adapter must be connected to the very base of the boiler drum.

The bottom of the plastic case must be laid out metal mesh... It will act as a barrier against steel wire pieces falling out. With short wire lengths, the entire pipe cavity must be filled. It's good if the pieces are short, no more than 5 centimeters. This will fill the pipe more thoroughly.

Plastic pipe as body

The induction coil is the main heating element in this design. It is necessary to make a coil for a boiler from enameled copper wire. On the already prepared building of the future electrical appliance you need to wind this copper wire. 90 turns.

An important point: during winding, you need to ensure that the distance between the turns is as equal as possible. The inductor is now ready for connection to the heating system.

As a result of this work, it turns out small size a device that connects to any part of the heating system. It is only necessary to cut out a piece of the pipeline, and instead, using adapters, install an induction apparatus. It must be remembered that the coil is connected to a high frequency inverter. And it can only be used in systems filled with a heat carrier: water, antifreeze, oil, and so on. Otherwise, the body will not withstand heat and melt.

As a result, very little money was spent on the manufacture of an induction boiler. In this case, the heating rate is doubled.

Second type of boiler

There are other ways to create such heating devices. Consider the second type of induction type boiler. It will cost more, but the result will please you even more.

The master must have more serious skills. Experience with welding is desirable. You will need a three-phase stationary inverter, additional tools.

This homemade induction boiler already includes two pipes. One is attached inside the other by welding. The device will perform two functions at once. On the one hand, this is the core - the source of the electromagnetic field, on the other - the heating element.

Copper wire wraps around the outer pipe. The result is high efficiency, compact dimensions and light weight of the device. Nozzles are used to supply the coolant.

Outer tube winding

Dignity

During the independent manufacture of induction boilers, it is necessary to adhere to some rules.

The induction boiler device can only be installed in. They must be used in them. In this case, the pipes in the system can be any, even plastic.

Care must be taken that the distance between the induction electric boiler and other objects (furniture, household appliances) was at least 30 cm. To avoid damage to property. Do not mount the device too close to the ceiling. The distance should not be less than 80 cm.

It will take a little longer to work on the second version of the boiler. However, reviews of the induction boiler say that the labor costs are worth it. Such a device will effectively heat the house for at least a quarter of a century. No additional service required.

Advantages of induction boilers:

• use of both alternating and direct current is allowed;
• all elements of the device are durable;
• elementary construction;
• there is no need to allocate a special place for the boiler room;
• fire safety class belongs to group 2;
• The efficiency of a boiler that is made by hand or bought in a store is almost 100 percent;
• the type of coolant can be any;
• on the self-production minimum costs are required.

It is obvious that the induction type is a modern device that has all the qualities of the technology of the future. Highly efficient, low-cost unit is able to quickly heat and country cottage, and a summer cottage, and a storage room. At the same time, there are no difficulties in installation. And no maintenance costs.
