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?

By 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, any person who at least once had 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 the 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 working 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 improve 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 make this heating device with their own hands. However, don't expect it to be easy. We'll have to stock up on the necessary materials and tools. Also, the advice of other craftsmen who have experience in creating such 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 pay off the time and money spent on its manufacture and installation. Moreover homemade induction boiler heating will help you save money during its operation.

In the process of planning the installation of a heating system in a country house or in a country house, many are trying to solve the problem of excessive energy costs by installing an induction heating boiler. In addition to saving energy, its device is such that it allows you to do without harmful emissions into the environment and does not pose any danger during use. An important argument in its favor is the possibility of its independent design. In this article, we will consider what an induction heating boiler is: everything about the principle of operation + 2 options for a device with our own hands. In addition, its advantages over conventional electric boilers and gas units will become obvious to us.

The device of induction boilers

An inductor (transformer) is included in the basis of the internal structure of such a boiler. Conventional household induction boilers are slightly different from similar industrial boilers with a cylindrical winding system. In compact boilers for domestic use, a toroidal copper winding is used.

The outer casing of the unit is made of painted metal, followed by a thick layer of thermal and electrical insulation, inside which there is a double-walled core. It is made of special ferromagnetic steel and has a wall thickness of at least 10 mm. The toroidal winding that is wound around the core is the primary winding. It is in it that the energy of the electric field is converted into a magnetic field, which creates eddy currents. Their energy is already transferred to the secondary winding. The role of the secondary winding is the body of the circuit, which, under the action of this energy, releases a large amount of heat, which is transferred to the coolant. Toroidal winding allows you to create units with low weight and dimensions.

The principle of operation of induction boilers

The standard equipment usually includes the boiler itself, an absolutely necessary semiconductor converter called an inverter, circuit breakers, an electronic thermostat. The temperature sensor itself is located inside the boiler drum.

The operation of induction boilers is based on the principle of electromagnetic induction. Its essence is that the electricity consumed from the network creates an electromagnetic field. The heating medium is supplied to the inside of the boiler through the water pipe, which is welded at the bottom. An alternating current with a frequency of 20 kHz is supplied to the boiler through an inverter. When this device is turned on, the current flows through the toroidal winding of the boiler. At the same time, the steel core heats up to a temperature of 750 degrees in just 7 minutes.

The generated heat is transferred to the heat carrier circulating inside the circuit. Rapid heating of the liquid creates convection currents. This means that the heated coolant expands strongly and rushes up the boiler structure and further into the heating system itself. Often this is enough for a full-fledged operation of a household boiler with an average length of the heating circuit to take place. This method allows you to quickly heat the entire system, but for better circulation, you need to additionally install a conventional circulation pump.

Due to the application of the principle of magnetic induction, heating of the coolant in such boilers occurs much faster than in units with heating elements, and heat losses are minimal. There is almost no scale on the core, no matter how hard and calcareous the water is.

This is because the eddy currents force the core to vibrate, preventing scale build-up. At the same time, bubbles boiling at his body clean the surface of the core. Due to the tightness of the entire system, the coolant takes up the maximum (98%) amount of released thermal energy. Thus, these parameters greatly increase the efficiency of the boiler, which has a positive effect on its efficiency and service life.

Pros and cons of induction boilers

Induction boilers have a number of unconditional advantages over conventional boilers with heating elements:

• Stable efficiency rates up to 99% for almost the entire service life.
• The absence of heating elements, which significantly extends the life of the device.
• The absence of moving elements, which completely eliminates mechanical wear and the need to replace components.
• The absence of detachable internal connections prevents leakage.
• Full availability of work even with constant current or low voltage in the network.
• Very fast heating to the required temperature of the coolant (5 - 7 min).
• A sufficiently high degree of electrical and fire safety, corresponding to class II due to the use of a core that is not directly connected to the inductor.
• No need to install a chimney and provide a separate room for the boiler. There is no need to hire highly qualified specialists to install this system.
• The standard service life of the device is up to 25 years and even more. It directly depends on the tightness of the sealed external seam and on the large thickness of the metal pipes for the core. He does not need any maintenance work during the entire period of operation.
• The boiler can use all available heat transfer fluids: oil, water, antifreeze, ethylene glycol without any preliminary preparation.
• It is possible to change the development of the coolant only once every 10 years.
• Good protection against overheating and various accidents, noiselessness during operation.
• The boilers are equipped with electronic automated control systems.
• There is no scale inside the circuit.
• Possibility of connecting the boiler to any closed-type heating systems.
• The minimum possible heating of the coolant is 35 ° C.

But induction boilers have disadvantages, both in front of other heating devices and in terms of individual specific parameters.

• Such boilers can only be connected to a closed heating circuit, very often with forced circulation of the coolant
• Quite a large weight of the boiler with a fairly small size. The weight of a 2.5 kW boiler is at least 23 kg with a total height of 45 cm and a diameter of 12 cm.
• The price is higher than that of other boilers, which is due to the presence of an expensive part - an inverter.
• Radio interference generated at a distance of several meters from the boiler in the long-wave, medium-wave and even VHF ranges. They do not affect the human body, but they are well felt by pets and electronic equipment.

Installation of an induction boiler and control system for it

Installation of such boilers is possible only in a closed heating system. This requires an expansomat expansion tank and a pump for forced circulation of the coolant.

According to the instructions, the induction boiler is positioned strictly vertically. After that, the return pipe of the heating circuit is connected to the lower branch pipe of the input. The outlet is located at the top of the device (side or top). The supply pipeline is looped onto it.

The weight of the boiler to be mounted is quite serious, therefore the most special attention should be paid to the fastenings. They must be very reliable, taking into account the fact that during the operation of the boiler, its weight will significantly increase due to the coolant entering the interior. The lateral distance from the boiler to the surrounding objects and walls is 300 mm. The distance to the floor and ceiling is 800 mm and no less. An important and prerequisite for the installation of such boilers is their grounding. It is possible to use both metal and metal-plastic pipes with it.

A group of safety devices is built in next to the outlet pipe: an explosive valve, a pressure gauge, an air vent. The expansion tank is installed in a convenient section of the system return pipe. The shut-off valves are mainly installed after the safety group.

The installation of the entire control system, as well as the boiler itself, must be carried out in accordance with the existing rules and regulations of the PUE, diagrams and conditions contained in the technical passport included in the kit.

Examples of homemade designs

If you are not going to use an induction boiler for the main heating in a private house, but want to equip a summer cottage or garage with it, then you can try to design it yourself. There are two options for how to do this.

First option

To implement it, you will need pieces of plastic pipes and a welding inverter. Having basic knowledge in the field of physics and knowing how to use wire cutters, you can independently make an elementary induction model. To do this, you need to purchase an already created high-frequency welding inverter with a smooth regulation of the current power up to 15 amperes or even higher. For heating a large area, it is better to choose a much more powerful device. You will also need stainless steel wire rod or regular pieces of steel wire. This is necessary to fulfill the role of a heated element. Their length is about 50 mm, with a diameter of 7 mm.

An important component is copper wire, which can be purchased without any problems at any theme store. Do not use winding from old coils. The body, which is the basis of the induction coil, is also part of the pipeline, so it can be made from a plastic pipe with thick walls. Its inner diameter should be 50 mm. Two outlet pipes are attached to this body for the supply of cold and return of the hot coolant. The entire internal space of the case must be completely filled with pieces of wire and covered with a metal mesh so that they do not spill out.

An induction coil is made as follows: a copper wire covered with enamel is gradually wound around a previously prepared plastic pipe. It will take about 90 turns. The resulting homemade device must be connected to the pipeline network. A small section of the pipe is cut out of the pipeline, and a homemade induction boiler is installed instead. It is connected through an inverter and the water is simply started.

Second option

This option provides for the use of a three-phase transformer with the possibility and fixation. In addition, you will also need a welding machine. To manufacture the device, you need to weld two pipes in such a way that they look like a donut in a cut. This design performs both conductive and heating functions. Then the winding is wound directly onto the boiler body in order to make it work more efficiently, despite its low weight and size. Here, a standard heating medium heating scheme is used: it receives a large amount of thermal energy in contact with the winding.

The manufacturing scheme of such a structure is somewhat more complicated than in the first version. The boiler is equipped with two nozzles, both for the inlet of the cold heat carrier and for the outlet of the heated one. If you come up with and independently build a protective casing, you can minimize heat losses.

Features of self-installation and operation of homemade boilers

As in the case of factory-made boilers, only a closed-type heating system may be suitable for installing a home-made induction installation. It should include a centrifugal pump, which creates a constant circulation of the coolant inside the heating system. Plastic pipelines common today are the best fit for installing a homemade induction boiler. All regulations relating to the installation of store-bought boilers must be fully observed in this case. If you install controls and safety devices on the system, then your homemade installation will not be inferior to its factory counterparts.

Although it is quite difficult to make such a device, and it is better not to take up this business without having "direct hands", it is a pleasure to operate it. Indeed, along with the ease of use, we also get serious energy savings.

Induction heating boilers appeared on sale recently and immediately competed with the usual electric boilers with heating elements. With similar dimensions and power consumption, induction heaters are able to warm up the system much faster, in addition, they can operate in systems with a low quality of the coolant and require less maintenance. Applying knowledge in electrical engineering and ingenuity, you can make an induction heating boiler with your own hands.

The operation of induction boilers and other heating devices of this type is based on the ability of conductive materials to heat up under the influence of eddy currents created as a result of electromagnetic induction.

The source of induction is a high-frequency alternating current passing through the primary winding of the heating device, made in the form of a coil. A heating element placed inside the coil acts as a secondary short-circuited winding. It converts electromagnetic energy into thermal energy.

Eddy currents also occur at an industrial frequency of 50 Hz, but the efficiency of the heater will be low, and the operation of the device will be accompanied by a strong hum and vibration. When the frequency is increased to 10 kHz and higher, the noise disappears, the vibration becomes imperceptible, and the heating increases.

Device

An industrial induction boiler consists of a core, the role of which is played by a heat exchanger, around which a toroidal winding is wound, connected to a high-frequency converter. When a current passes through the winding, an alternating electromagnetic field is created, as a result of which eddy currents arise, passing through the core.

The winding is connected to a high-frequency converter, in which a signal from the control unit creates a current of the required frequency. Modern boilers have a high level of automation, which allows not only to create an optimal heating medium heating mode, but also to turn off the device in case of an emergency.

The heat transfer medium is located inside the heat exchanger core. Under the influence of eddy currents, it heats up to high temperatures. Due to the difference between the temperature of the coolant at the inlet and outlet, from the boiler, the coolant circulates through the system continuously, even without connecting the pump. Therefore, induction boilers can be used in systems with forced and natural circulation.

The coolant can be both water and antifreeze, antifreeze, oil. In this case, the quality of the liquid does not matter: the constant vibration of the system, imperceptible by a person, makes it impossible for scale and other impurities to settle on the walls of the thermal circuit.

Outer shell- a metal case equipped with a thermal and electrical insulation system.

Boiler shape it can be any, as well as the method of its installation: due to the absence of a tank inside the boiler, its dimensions are usually small, and its mass does not exceed 50 kg.

An induction boiler cannot even be switched on for a short time without filling the system with a coolant! Boiler overheating and failure of its components may occur!

Advantages:

• High efficiency. Most manufacturers cite the figures as 95-98%;
• A large selection of models of various capacities for single-phase voltage ~ 220 V or three-phase ~ 380 V;
• Rapid heating of the heating system at startup;
• They can work with any coolant;
• The circuit through which the coolant passes inside the boiler is absolutely sealed, which excludes leaks and related malfunctions;
• Long-term operation without the formation of limescale and deposits. It is this phenomenon that over time reduces the efficiency of boilers with heating elements and is a frequent cause of their breakdown due to overheating of heating elements;
• The service life declared by the manufacturers is from 25 to 30 years.

Heaters are not devoid of disadvantages, the most significant of which is the high price. This factor usually prompts a prudent owner to assemble a homemade induction boiler from scrap materials and devices. Despite the complexity of the processes taking place in boilers of this type, it is possible to create a structure that does not lag behind industrial-made boiler in basic parameters, and to make an induction boiler with your own hands.

Boiler powered by a welding inverter

The design of such a homemade boiler is quite simple. The most difficult block for independent execution, requiring knowledge of the basics of electronics and electrical engineering, is a high-frequency converter. Its function is perfectly performed by a modern-type welding inverter, capable of producing an output signal with a frequency of 20-50 kHz.

In addition, installation will require:

• copper wire in enamel insulation with a diameter of 1-1.5 mm;
• insulated wire with terminals for connecting the winding to the inverter;
• trims of stainless steel wire with a diameter of 3-5 mm, a length of 5 cm;
• fine stainless steel mesh;
• a section of a water pipe made of sewn polyethylene or polypropylene for hot water supply and heating systems with a diameter of 50 mm and a wall thickness of 8.4 mm, length - 1 m;
• adapters from a 50 mm pipe to pipes used in an existing or projected heating system, a tee for connecting an emergency valve and two ball valves;
• PCB strips for fastening the winding;
• epoxy adhesive for winding insulation;
• the body of a home-made boiler, it can be made from a distribution metal or plastic cabinet in which an inverter can be installed and a heating element fixed.

The sequence of assembly and installation of elements:

1. On a piece of polypropylene pipe with a diameter of 50 mm, 4 strips of textolite 8-10 mm wide are attached using epoxy glue, departing from the ends of the pipe by 70-100 mm. A winding will be wound around them. To fix the extreme turns of the winding in the PCB, you can make grooves.
2. 50-100 turns of copper wire in enamel insulation are wound. The turns should be approximately 0.3-0.6 mm apart at an equal distance. The exact number of turns depends on the diameter of the wire used and its resistivity, as well as the output parameters of the inverter.
3. When installing a home-made boiler in a residential area, it is recommended to perform a toroidal winding to reduce the external electromagnetic field. The toroidal winding consists of the same number of oppositely directed turns, while the electromagnetic fluxes are mutually compensated and pass only along the inner loop.
4. A stainless steel mesh is inserted inside the pipe from one end of it and tightly packed on the other side with pieces of stainless wire - it will heat up under the influence of eddy currents. It is recommended to use stainless steel so that corrosive destruction of the wire does not occur over time, but theoretically any conductive metal, including wire rod, is suitable. The other end of the pipe is also covered with a mesh.
5. On both ends of the pipes, polypropylene adapters are soldered to the diameter used in the heating system. Ball valves are installed on them to shut off the circulation and remove the heat exchanger for revision.
6. An emergency pressure relief valve is installed on the side of the upper outlet adapter.
   The winding is coated with epoxy glue to ensure high-quality electrical insulation of the winding. It is recommended to make glue with a slight deviation from the instructions, adding 10-15% less hardener. This will make the insulation less brittle.
7. Fastened to the terminals of the winding wire in isolation using crimp terminals. The other end of the wire must be equipped with terminals for connecting to the inverter. The wire diameter must be suitable for the maximum output current of the inverter.
8. Install the heat exchanger in the cabinet, fixing it to brackets made of heat-resistant, non-conductive material. You can use textolite.
9. Connect the heater to the system and fill it with water.
10. An inverter is placed in the lower part of the cabinet. Connect the terminals to it and include it in the network. The boiler is started and the mode is set.

The metal cabinet body must be grounded!

From induction hob

An induction boiler can also be made on the basis of an induction hob. To do this, the heating element of the tile is disassembled and a copper wire is used for winding on a core made in the above way.

The tile control unit is used to power the resulting winding, setting the required power on the touch control panel.

However, this method has significant drawbacks:

• For the successful operation of such a homemade boiler, you need to calculate the parameters of the inductance of the newly assembled coil. They may not match those for which the tile electronics are designed, as a result of which the control unit may fail. For calculations, you need to have good knowledge in the field of electrical engineering and be able to understand the connection diagram;
• Most stove models are equipped with an automatic shutdown 2-3 hours after the start of the burner. This will lead to regular shutdown of the boiler;
• Induction-type tiles usually have a power of no more than 2.5 kW, therefore, they are suitable only for conversion to a low-power boiler.

Errors in the device of an induction boiler from a tile are shown in the video:

An easier way to use an induction hob, excluding the disassembly of the device and the installation of a new circuit - install on it a sealed stainless steel tank of a suitable size with inlet and outlet fittings and connect it as a boiler to the heating system. Almost everyone can handle such a connection scheme.

If you have the necessary knowledge and ability to understand the circuits, you can follow the example of the author of the video and assemble a functional induction boiler from a tile, modifying its circuit.

Dry type heater

The principle of operation of an induction boiler involves the use of water or other liquid not only as a heat carrier, but also for cooling the core. But the heating of the secondary winding, the role of which in this device is played by a pipe with water, will also occur if it consists only of metal.
The degree of heating in this case depends on the ratio of the strength of the electromagnetic field created by the winding and the mass of the core metal. After making the calculations, you can create a dry induction heater with your own hands from metal pipes and copper windings, as shown in the video.

The use of an induction boiler is cheaper than a conventional electric boiler with heating elements, and a homemade design will significantly reduce the cost of installing it. Similarly, you can assemble a flow-type water heater for installation in the country, choosing a device of the required power.

Do you want to equip your home with efficient and cost effective heating at the same time? Then be sure to pay attention to modern induction boilers. Such units are characterized by high productivity and at the same time have an extremely simple design, so you can easily handle the assembly of an induction heating boiler with your own hands. The operation of the equipment under consideration is based on the use of induction electrical energy.

Such boilers are absolutely safe and environmentally friendly. During their operation, no by-products are released that can harm humans and the environment.

By design, such boilers are a kind of electric inductors, which include two short-circuited windings.

So, the inner winding is responsible for converting the incoming electrical energy into special eddy currents. An electric field is formed in the unit, which then enters the secondary coil. The latter simultaneously serves as a heating element of the heating unit and the boiler body.

The secondary winding is responsible for transferring the generated energy directly to the coolant of the heating system. Special oils, non-freezing liquids or pure water are used as a heat carrier in such installations.

The inner winding of the heater is exposed to electricity. As a result, some voltage appears and eddy currents are formed. The generated energy is transferred to the secondary winding, after which the heating of the core begins. Upon reaching the heating of the entire surface, the coolant will begin to give heat to the radiators, and they - to the heated rooms.

Is it rational to assemble the boiler yourself?

Induction heating boilers have the simplest design, there are no difficulties with their assembly. However, you will definitely have to at least carefully study the proposed instructions and make an effort to correctly assemble a high-quality unit.

The reward for your efforts will be efficient and financially profitable heating equipment. To assemble the boiler, you do not need to buy any expensive components - all the necessary elements are sold in ordinary construction, household and other specialized stores.

Provided it is properly assembled and properly handled, the finished unit will last 20 years or more. The main thing is to do everything in strict accordance with the instructions.

Super complicated tasks are not set for you, and it is almost impossible to make any critical mistakes when assembling an induction boiler according to the instructions.

Assembling a simple induction boiler

To assemble an induction boiler, you do not need to use any complicated tools and expensive materials. All you need is to have at least a basic understanding of the operation of an inverter-type welding machine.

First step. Cut a stainless steel wire or wire rod into pieces about 5 cm long. The required diameter of the wire used is 7-8 mm.

Second step. Prepare a plastic tube for assembling the device body. A product with a diameter of about 50 mm will be enough.

Third step. Close the bottom of the main pipe with a fine-mesh metal mesh. Choose a mesh with such cells so that pieces of loaded stainless steel or wire rod cannot pass through them.

Fourth step. Fill the body completely with wire or wire rod, and then close the free opening of the tube with a second metal mesh.

Fifth step. Carefully and as tightly as possible wind about 90 turns of copper wire around the middle part of the case.

Sixth step. Connect special adapters to the heater body for tapping into the heating or plumbing system. The scheme is extremely simple: water enters the heater through one adapter - it heats up almost instantly - it enters the heating system through the second adapter - the batteries and pipes give off heat to the serviced room.

As a result of such simple manipulations, you will get an inexpensive and extremely easy-to-assemble device for efficient heating. The advantage of using a home-made induction boiler is that there is no need to allocate a separate boiler room for its installation. You simply cut out a piece of pipe near the entrance to the radiator and attach your homemade heater instead.

Important: do not turn on the heater if there is no coolant in the heating system. In such a situation, the plastic body of the heater will simply melt and all your work will go to waste.

Remember to securely ground your homemade heating device.

The device of the vortex induction heating unit

Assembling such a unit will require you to have certain skills in handling a welding machine, as well as a three-phase transformer. The advantage of a vortex heater is the absence of elements in its composition that are not capable of withstanding intense loads for a long time. That is, the risk of an early failure of the boiler is reduced by an order of magnitude.

Also, among the advantages of the unit in question, it is necessary to include the absence of detachable connections. This allows you to completely forget about the risk of leaks.

Homemade vortex induction boiler operates in almost silent mode. This allows you to mount it anywhere you want. There are no harmful fumes either, so you don't have to worry about the need to equip a reliable boiler room and install a chimney.

First step. Weld together a pair of metal pipes with a diameter of about 2.5 cm so that the result is a round product. The resulting workpiece is simultaneously a heating element of the boiler and its core.

Second step. Place the resulting circle in a suitable sized plastic tube.

Third step. Wrap on a plastic case from materials you are already familiar with. Thanks to such a winding, the efficiency and productivity of the unit will be significantly increased.

Fourth step. Place the plastic case in a quality insulating cover. It will prevent possible electrical leakage and will significantly reduce heat loss.

Heating will be carried out due to the contact of the coolant with the same winding. The winding and all further actions are carried out in the same way as in the case of the ordinary induction installation discussed in the previous instruction.

Important notes on the installation and use of the boiler

Homemade induction boilers are extremely easy to assemble, install and operate. However, before you start using this kind of heater, you need to know several important rules, namely:

It is strongly recommended to equip the boiler branch pipe with a blasting valve. Through this simple device, you can, if necessary, rid the system of excess air, normalizing pressure and ensuring optimal operating conditions.

Thus, from inexpensive materials using the simplest tools, you can assemble a complete installation for efficient space heating and water heating. Follow the instructions, remember the special recommendations and very soon you will be able to enjoy the warmth in your own home.

Happy work!

Video - DIY induction boiler

When choosing a boiler for heating a house, the owners are guided, first of all, by what kind of heating source is available for the room. Gas is the cheapest fuel, but settlements are far from supplied. Electricity is the most common, but not the cheapest. An induction heating boiler produces a fairly high efficiency, with less electricity consumption compared to other electrical options.

The basis of the principle of operation of the boiler is the creation of thermal energy from electrical energy. The action of electromagnetic induction is as follows - through a coil wrapped in wire, we pass a current, an electromagnetic field arises around this winding. A metal core placed in the coil (which has the property of being attracted by a magnet) will begin to heat up quickly.

Heat Generator Mechanism: It is an electrical inductor made up of primary, secondary and core. By converting electricity into eddy currents, the primary winding directs the electric field to the secondary winding, which in turn transfers energy to the carrier. Under the influence of the electromagnetic field, eddy currents are generated in the body and core. They heat up the metal. Water takes heat from the core and distributes it throughout the building.

The operation of an induction hob is based on the same principle. Such tiles are much more economical than conventional electric stoves. This is achieved by avoiding heat loss by transferring heat from the heater to the cookware. Marketers today designate induction heating boilers as advanced developments created on a new principle. But in fact, this is not entirely true. Inductive principles have been applied since the last century for smelting furnaces. Also, no new materials are used for the manufacture of boilers.

M. Faraday discovered the phenomenon of induction in 1831.

Induction options are safer compared to other heating boilers, they practically do not need maintenance. They do not contain dynamic parts and, as a result, have no mechanical wear. With sufficient cooling, the coil's lifespan is unlimited. Such boilers do not require a separate room. In comparison with, they practically do not need preventive work.

Induction boiler advantages:

• Constant circulation of the coolant;
• Lack of heating elements;
• Silence.

An inductive electric boiler is able to heat not only the area of ​​a small private house, but also industrial premises, while there is no need for large installation and maintenance costs. Induction heating boilers on the market are not cheap. The reason is in the sensors of the system. The inverter used in the control system increases the cost of the heating boiler.

How to make an induction heating boiler with your own hands

Opponents of the installation of induction boilers cite the conservation law - 1 kW of electricity is able to generate heat energy also no more than 1 kW. Yes, any water heater, consuming 1 kW of electricity, also produces 1 kW of energy. But not all of it is warm. Induction water heaters are more productive in the production of thermal energy, in comparison with heating elements. Making a homemade inductive water heater is not difficult. The materials used in this case can be found without much difficulty and at a low price. The circuit for such an inductive device is quite simple.

To convert electricity into heat, you need:

• Inductor;
• Alternating current 50 Hz;
• The core is made of the material to which the magnet "sticks";
• Drawings of an induction heating boiler (not a problem to find).

For the body of the induction boiler, you need to take a pipe with a diameter of 5 cm. The pipe is filled with pieces of wire, 5-7 cm, with a diameter of no more than 7 mm. To connect the boiler to the pipe system, you need adapters. The heating system diagram will help determine the characteristics.

It is better to install an automatic power outage in the event of a coolant leak. In this case, the electromagnetic field will not disappear if the power supply is not turned off, and the case with the fasteners will simply melt.

We make an induction coil - the main heating element. To do this, we take a copper wire, wrap it around the body, approximately 85-99 turns. The interval between the turns is equal. The simplest induction boiler is ready. Such an inductor can be installed anywhere in the pipeline. An induction steam generator works on the same principle.

Induction heating modernization

Induction heating systems often have favorable reviews. Silence, efficiency and longevity are the indisputable advantages of the heating system. One of the varieties of the system is the operation of an induction water heater for heating. An induction water heater can be purchased and installed in the pipeline system.

You can choose an induction heating scheme with your own hands. In this case, you can save your money well.

But, for a more efficient operation of the induction system, it is important to know some of the nuances. By installing an induction cooker in the structure, it is connected to a charger, batteries and an inverter. An inverter is a device that converts direct current into alternating current. Its use reduces the amount of electricity consumed for the heating system to virtually zero.

For less energy consumption, you need:

• Inverter 4 kW;
• 2 batteries 250 A * h;
• Battery charger.

We connect 2 batteries synchronously, and charge them. They generate direct current and supply it to the inverter. The inverter converts DC to AC. The inverter then transfers current to the induction cooker and the charging charges the batteries continuously. Thus, the consumption of the 24 V charger is the energy consumption of the induction heating of the house. The costs for the pump are calculated separately. Induction heaters are used only in versions with forced circulation.

Description of inverter heating boiler

The inverter boiler has become available to the household consumer, in contrast to industrial enterprises, relatively recently. At the heart of the boiler device are 2 main cylinders placed in the outer one. The variant of such a boiler is safer. With proper installation, fire safety is orders of magnitude higher compared to gas, coal and wood-fired boilers.

The principle of operation of the inverter boiler:

• The coolant flows in the inner cylinder;
• The cylinder, which passes the current through itself, provides heating of the coolant;
• The outer cylinder acts as a heat insulator;
• The basis of the boiler operation is electromagnetic induction.

The mechanism of the inverter boiler practically eliminates the leakage of the coolant. An important quality is that any option can be used as a heat carrier (water, antifreeze, oil). The advantage of using antifreeze is that when the boiler is turned off in winter, the battery will not freeze or burst. Inverter boiler models of small capacity often have the ability to operate on battery power, which significantly reduces energy costs.

When installing an inverter boiler in a heating system, it is important to connect the ground correctly.

The inverter system will allow you to quickly reach the desired temperature, and will provide an economical consumption of electricity. Such systems are successfully used in the production of split-systems. The inverter air conditioner has a much longer service life than standard split systems.

Induction devices are practical and economical systems that do not require difficult installation and maintenance. As a rule, small dimensions allow installation in any premises, and do not require rebuilding the heating system. The fire safety of induction heating boilers allows them to be used in country houses, even if the owners do not appear there often.
