Homemade induction heater for heating. Induction heating boiler: advantages of use and do-it-yourself manufacturing technology

A DIY induction heating boiler is a profitable option that will help to heat economically a private house, apartment or non-residential building.

Such devices have high productivity and simple type designs. The operating principle of this system based on induction electricity.

The advantages of the heating device are the elements included in the composition that can withstand heavy loads. The risks of early heating boiler breakdowns are minimal. And also in the project of the device in question there are no detachable connections, which guarantees no leaks. A home-made heating boiler operates silently, which makes it possible to install it in a convenient place.

Installation of an induction boiler for heating a private house

The equipment is intended to convert electricity into heat energy using the device.

Induction units can quickly increase temperature coolant, unlike heating elements. An important part of the device is the transformer (inductor), which consists of two types of winding.

A current is generated inside, which is of the vortex type, then the energy is supplied to a short-circuited coil, which also serves as a housing. When the secondary winding receives sufficient quantity energy that instantly converted into heat, heating the coolant.

Inductor

This element is an important component devices in which an alternating magnetic field appears, The device consists of two types of winding- primary and secondary. Made from stainless wire on a plastic body. This method increases the efficiency and productivity of the unit. To make the body of the device you will need a thick plastic pipe diameter 5 centimeters. It will serve as the basis of the induction coil and will be part of the heat pipe.

Inverter

This component takes household type electricity and converts it into high frequency current. After which the energy is supplied to the primary winding of the inductor.

A heating element

For the preparation you will need two metal pipes , which have a diameter 2.5 cm. The products should be welded together, making the part shape round. The mechanism will serve not only heating element, but also the boiler core.

Photo 1. DIY induction boiler. There is a heating element located inside the structure.

Pipes

One pipe serves as For the flow of coolant into the boiler, second for supplying heated water to the heating system.

Reference. The principle of calculating the inductor depends on required power boiler for heating the room. Calculation formula: 1 kW per 10 square meters room area, with a ceiling height not exceeding three meters. For example, a room with total area 160 m2 will heat an induction boiler with power 16 kW.

The mechanism of heating from an induction cooker

Design boiler is based on electric inductors, which include 2 short-circuited windings. The internal winding converts the incoming electrical energy into eddy currents. An electric field arises inside the unit, which then enters the second turn.

The secondary element functions as a heating element heating unit and boiler body.

Transfers the generated energy on the coolant of the heating system. Special oil, purified water or non-freezing liquid are used as coolants intended for such boilers.

The internal winding of the heater is exposed to electrical energy, which contributes to the appearance of voltage and the formation of eddy currents. The resulting energy is transferred to the secondary winding, after which the core heats up. When the entire surface of the coolant has been heated, it will transfer the heat flow to the radiators.

How to make the device yourself

You can make an induction boiler with your own hands, the main thing is to follow the instructions below.

Required tools and materials

Wire cutters, pliers.
Circulating pump.
Inverter welding.
Ball Valves and adapters will be required when installing the unit to the heating system.
Copper, steel or stainless steel wire. It is better to purchase new materials, since it is better not to use winding from old coils. Wire cross-section suitable for winding the pipe - 0.2 mm, 0.8 mm, 3 mm.
A piece of plastic pipe - frame designs.

Work order

To assemble a simple induction boiler, you do not need to use complex tools and expensive materials.

All you need is welding machine inverted type. Basic and step by step steps manufacturing:

Cut steel or stainless steel wire into pieces using wire cutters from 5 to 7 cm.
Plastic pipe for assembling the device body with a diameter of 5 cm. The pipe should be tightly filled with cut pieces of wire and laid so that there is no empty space inside.
A fine-frequency metal mesh is attached to the end parts of the pipe.
Short lengths of pipe are attached to the bottom and top of the main pipe.
Wrap the pipe tightly with copper wire, number of turns not less than 90. The same distance should be maintained between the turns.

Important! All open areas copper wire should be insulated special materials, which have good electrical and thermal conductivity. Induction boiler requires mandatory grounding.

Special adapters are connected to the body of the heater, designed for insertion into heating or plumbing structures.
A circular pump is installed.
An inverting element is connected to the finished coil at 18-25 A.
The heating system is ready to be filled with coolant.

Attention! Do not start the heating boiler if there is no coolant in the design. Otherwise plastic material the casing will begin to melt.

The result is an inexpensive, uncomplicated unit that will effectively heat the room being served.

A heating system is suitable for installing an induction system. closed design with pump, which will create water circulation in the pipeline.

Pipes made of plastic are also suitable for installation work when connecting homemade heating device.

When installing, be sure to maintain a distance from nearby objects. According to safety rules, there must be a distance between the heating unit and other objects and walls. about 30 cm or more, from floor and ceiling 80 cm and more. It is recommended to install a device for measuring liquid pressure in a confined space and a manual air vent at the outlet pipe.

Does the induction heating circuit provide any real advantages? How economical is it compared to heating elements? How does an induction boiler work? Is it difficult to assemble it yourself? Let's try to answer these questions.

The photo shows a homemade induction boiler.

What it is

The essence of the phenomenon of electromagnetic induction, discovered by Michael Faraday in 1831, is that a conductor placed in a magnetic field is excited electricity. The effect, in particular, formed the basis of the operating principle of any modern transformer.

If you wind two insulated windings around a ferromagnetic core and apply, say, 220 volts to one of them, then a voltage will arise on the second, related to these 220 volts in the same way as the number of turns of the secondary winding is related to the number of turns of the primary.

The voltage can be removed from the transformer windings necessary characteristics and use it to operate an electric motor or electronics. What if a ferromagnet that is not connected to anything is placed in the winding that generates eddy currents?

Obviously, the resulting EMF (electromotive force) is completely converted into the kinetic energy of movement of its molecules. Simply put - in heating.

Help: this is exactly how induction works. kitchen stoves And melting furnaces in steel mills.

Thus, at the output we will get a ready-made .

You just need to solve a few technical problems:

Select a core made of non-corrosive material.
Isolate it from the coil, while ensuring the tightness of the structure.
Make sure that the coil itself does not overheat when large currents pass through it.

Advantages of an induction circuit

As a rule, the price of factory-made induction boilers is on average noticeably higher than that of heating element analogues, and starts from 20-25 thousand rubles with a 4-kilowatt device power.

Model	Electrical power, W	Cost, rubles	Manufacturer	Heating area
VIN-5	4250	27000	Russia	60-150
Indicator	4000	18000	Ukraine	200
Edison-5	5000	35000	Europe	100-120
INERA SAV	4500	30000	Russia	50-80

Manufacturers and sellers give two arguments to justify the higher cost:

An induction boiler is more durable compared to its heating element counterpart.
It provides significant (up to 40-50%) energy savings, which will allow the costs to quickly pay off.

Let's try to evaluate the veracity of both statements.

Durability

The claims that the induction design is extremely resilient and durable are absolutely true.

Causes?

There are no moving parts in the boiler. If so, there is completely no mechanical wear of the structure.
It is free from the main problem of heating elements - liming of heating elements. Limescale gradually insulates the tubular heaters and causes them to overheat.

It’s curious: when eddy currents are excited in the core of the inductor, it vibrates barely noticeably, which promotes self-cleaning of the surface.

Economical

Let's remember the basics of physics.

From the point of view of Sir Isaac Newton, energy does not go anywhere and does not come from anywhere. A perpetual motion machine is impossible; To heat a fixed volume of air by 10 degrees, you need to spend a strictly defined amount of thermal energy, regardless of the design of the heater.

With any transformation of energy of any type, it ultimately either does physical work (that is, moves an object with non-zero mass against the gravity vector) or is used to heat the environment.

We emphasize: the efficiency of any electrical appliance direct heating is 100%.

All wasted electricity is completely converted into heat; For 1 kW of electrical power you can get 1 kW of thermal power.

Thus, the only thing that could theoretically explain the supposedly higher efficiency of an induction boiler is less heat dissipation in environment.

This argument does not stand up to criticism:

When installing a boiler in a heated room, the heat not absorbed by the coolant is still spent on heating.

50% lower heat loss with comparable or worse thermal insulation of the boiler body looks, to put it mildly, doubtful.

The conclusions are obvious:

The market value of induction devices is unduly inflated.
Their economy is, as one of Bulgakov’s heroes said, a typical case of so-called lies. The electrical power of the device is selected at the rate of standard 40 watts per cubic meter of heated room. Trying to heat a 200-meter house with a 4-kilowatt appliance will only lead to the recent buyer realizing that he was too naive.

crazy hands

Despite the piles of misinformation, the induction scheme itself more than has the right to life. Overpriced market price quite naturally leads to the idea of making induction heating boilers with your own hands. How to do it?

Frame

It should be:

Dielectric.
Durable enough.
Allowing it to be hermetically connected to the heating circuit.

The simplest and most obvious solution is a polypropylene pipe with a diameter of 40 millimeters. Ideally, with fiber reinforcement, which will have a very positive effect on the strength qualities of the body.

Winding

In order to isolate the inductor, which heats up when power is applied, from thermoplastic polypropylene, it is advisable to glue several textolite strips over the housing. What to glue with? The simplest and most obvious solution is silicone sealant: it has acceptable adhesion to plastics and tolerates moderate heat.

An important point: it is better to take sealants from reputable manufacturers (Ceresit, Moment, etc.).
Cheap sealants differ from them primarily in their much worse adhesion to problem surfaces, which, of course, includes smooth ones.

The coil itself is wound with enameled copper wire with a diameter of about 1.5 millimeters (section 2.25 mm2). The total length of the winding should be 10-15 meters. It is better to apply the coils with a small constant gap.

Core

What should it be like?

Conductive. Eddy currents will not be induced in the dielectric.
Ferromagnetic. A diamagnetic material will not interact with the electromagnetic field.
Stainless. Corrosion in a closed heating circuit is clearly of no use to us.

Here are some possible solutions.

A screw auger that fits tightly into the pipe. Moving along the grooves in it, the water will take away maximum heat.
Chopped stainless steel wire. It is not very convenient because the improvised boiler will have to be limited on both sides metal mesh.
Rolled from nichrome wire“hedgehogs” tightly inserted into the pipe.
Finally, the most simple instructions: In the same way, metal (stainless) dish scourers can be placed in the pipe.

After the core has taken its place, the boiler is equipped on both sides with adapters from polypropylene with a diameter of 40 mm to DN20 or DU25 threads. They will prevent the core from falling out and will allow the boiler to be mounted in any circuit, leaving the connections collapsible.

Power converter

What will happen if we simply connect the inductor we wound to a power outlet?

Let's do a simple calculation.

The resistivity of a copper conductor at +20C is 0.175 Ohm*mm2/m.
With a cross section of 2.25 mm and a length of 10 meters, the total resistance of the coil will be equal to 0.175/2.25*10=0.7 Ohm.
Therefore, when 220 volts are applied to the conductor, a current of 220/0.7 = 314 A will flow through it.

For comparison: when calculating wiring for copper, the cross-section is selected at the rate of 10 A/mm2.

The result is a little predictable: when a current is supplied more than 10 times higher than the calculated one, our conductor will simply melt.

The obvious solution is to reduce the supply voltage. The converter must be powerful enough to deliver at least 2.5 - 3 kilowatts.

A ready-made converter of such power can be a welding inverter with current regulation. The adjustment will not only protect the winding from overheating, but will also allow you to smoothly regulate the effective power of the heating boiler. With an inverter output voltage of 80 volts, the maximum safe power for the winding temperature will be about 2 kW.

Expenses

Of any significant costs, it is worth mentioning only a welding inverter (from 6,000 rubles) and a soldering iron for polypropylene (from 1,000 rubles). Another maximum of 1000 will cover all other purchases.

Conclusion

In this section we will try to explain the design of the boiler using an induction circuit, the difficulty of assembling it with your own hands, whether there are tangible advantages when using an induction heating circuit and how much more profitable it is than heating elements.

The concept of electromagnetic induction, which was discovered back in 1831 by Michael Faraday, is when a conductor placed in a magnetic field creates an electric current.

Every modern transformer works on this principle.

When two insulated windings are wound onto a ferromagnetic core and, for example, 220 V is supplied to one, the second begins to have a voltage that relates to these 220 V to the same extent as the size of the turns of the secondary winding concerns the size of the primary turns.

Transformer windings allow you to remove the required amount of voltage and use it in the operation of electronics or an electric motor. What if a ferromagnet, not connected to anything, is placed in a winding that generates eddy currents?

It is clear that the resulting EMF will be completely converted into the kinetic energy of movement of its molecules, or into heating.

Note: melting furnaces and cookers work exactly on this principle at steel mills.

Well, what if you place a ferromagnetic core in a water flow that is distributed along a closed circuit? It is clear that it will begin to be cooled by water, which will then itself heat up.

With this information, you can make an induction heating boiler with your own hands.

But first you need to deal with technical issues:

find a suitable core made of a material that does not corrode;
isolate it from the coil, while the impermeability of the structure must be ensured;
protect the coil from overheating when interacting with high currents.

The induction design is extremely durable and fail-safe for the following reasons:

There are no moving elements in the boiler, which means that wear and tear on its mechanical parts is completely eliminated.

Liming of heating parts, which is the main problem of heating elements, is not dangerous. Over time, lime scale leads to thermal insulation of the tubular heaters and subsequently to their overheating.

Interesting fact: during excitation in the core of the eddy current inductor, it vibrates very little noticeably. This function allows the surface to self-clean.

Typically, the price tags of boilers with a factory-produced induction circuit reach higher values than those of heating element analogues, and with a 4-kilowatt equipment power it starts from 20-25 thousand rubles.

Let's look at the characteristics of several designs available on Russian market:

Model	Price	Heating area	Manufacturer	Electric power
Indicator	18,000 rub.	200 sq. m	Ukraine	4 kW
INERA SAV	30,000 rub.	50-80 sq. m	Russia	4.5 kW
Edison-5	35,000 rub.	100-120 sq. m	Europe	5 kW
VIN-5	27,000 rub.	60-150 sq. m	Russia	4.25 kW

Justification highest price Sellers and manufacturers use the following arguments:

The durability of heating element boilers is significantly less than their induction counterparts.
Induction boilers are able to save up to 50% of electricity, which means a quick return on costs.

Below is a graph of electricity consumption for 7 months of the heating period. When using boilers of different designs, the provided table suggests a comparison of costs. There is no need to rush to believe her.

According to Sir Isaac Newton, energy does not come from anywhere and does not go anywhere.

A perpetual motion machine is not provided. To heat the specified amount of air by 10 degrees, you must strictly apply specific amount thermal energy, regardless of the design of the heater.

Every energy transformation, regardless of its type, carries out physical work or is used in heating the environment. It follows that the only theoretical explanation for the "type" of higher utility of an induction boiler is the least heat dissipation into the environment.

We clarify: all direct heating electrical equipment has 100% efficiency.

All involved Electric Energy completely turn into thermal power: from 1 kW of electricity it is possible to obtain 1 kW of thermal power.

These facts do not stand up to criticism:

When installing a boiler in a heating room, heat that could not be absorbed by the coolant is ultimately used for heating.

With comparable or worse body thermal insulation of the boiler, 50% low heat losses look dubious.

The market price of induction structures is too high.

Their efficiency is simply a lie. The electrical power of the equipment is selected at the rate of standard 40 Watt for a heated room with a volume of 1 cubic meter. m. If a recent buyer tries to heat a house of two hundred cubic meters with a 4-kilowatt device. m., he only realizes his naivety.

But, excluding all the misinformation that has been given to inductive constructions, there is a basis for its existence. The higher market price leads to the desire to build a heating boiler with an induction circuit with your own hands. And now we will find out how to do this:

To insulate the inductor, which heats up from thermoplastic polypropylene when power is supplied, it is recommended to cover the casing part with textolite strips.

The most in a simple way gluing is silicone sealant, it has the necessary adhesion to plastic structures, etc., and also withstands moderate heat well.

The coil must be wound with an enameled copper cord, which has a diameter of 1.5 mm and a cross-section of 2.25 square meters. mm. The entire length of the winding should reach 10-15 m. The turns are superimposed with a small constant gap.

Very important: the most suitable sealant option is considered to be from reliable manufacturers “Moment, Ceresit, etc.” Low-cost sealants have significantly worse adhesion to problem surfaces, which is the wall polypropylene pipe.

He must have:

dielectric characteristics;
sufficient strength;
and have a tight connection to the heating circuit.

A 40 mm diameter polypropylene pipe is the simplest and effective option. The most reliable solution is to add reinforced fiber, which will give the body highest strength.

It must have the following properties:

conductive - eddy currents will not be induced in the dielectric;
rust resistance - corrosion in a closed circuit will not do any good;
ferromagnetic - a diamagnetic material excludes connection with the electromagnetic field.

Solutions:

it must have chopped wire that does not rust - its inconvenience is the limitation of the improvised boiler on both sides with a metal mesh;
a screw auger that fits tightly into the pipe is an excellent solution - when moving along the ditches in it, the largest heat volume will be taken up by water;
“hedgehogs” rolled from nichrome wire, tightly placed in a pipe;
using the appropriate method, you can insert stainless steel kitchen sponges into the pipe.

Below is a drawing of a heating boiler with your own hands.

Electrical feed converter

What happens when we connect the inductive coil we wound to a socket?

Let's do a simple calculation:

The copper conductor has resistivity at 20C equal to 0.175 Ohm x sq. Mmm.

With a cross-section of 2.25 mm and a length of ten meters, the one-piece coil resistance reaches seven tenths of an ohm “10 x 0.175/2.25”.

Accordingly, supplying a conductor with 220 V, a current of 314 A “220/0.7” will pass through it.
For comparison: when calculating wiring for copper, it is charged at the rate of 10 A/sq. mm.

The result is completely obvious: if we apply a current ten or even more times higher than calculated, our conductor will simply succumb to melting.

The option to correct the situation gets stuck on its own - you need to reduce the supply voltage. The converter must be powerful enough to output at least 2.5-3 kW.

Welding inverter with control of electric current, it can be used under a ready-made converter of the required electrical voltage. Electric current control protects the winding from overheating and allows you to smoothly coordinate the involved power of the heating boiler. If the output voltage of the inverter is 80 V, then the maximum permissible temperature winding power is calculated at 2 kW.

Also, using this principle, you can make a heating boiler using diesel fuel with your own hands, which you have.

Today it’s hard to believe that heating can be economical. We either pay for electricity and gas, or burn great amount 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?

To operate such a boiler, you will still need electricity, but the bill won’t be so scary. The main advantage of such heaters is their design. They very profitably convert electricity into heat (the working environment takes almost 97%). This gives rapid heating at minimum costs. Working environment or the coolant for an induction boiler is most often untreated water, which is heated and distributed through the heating system of the house. But oil or antifreeze is quite suitable for this purpose.

The electricity conversion system consists of two windings. The first one accepts current from the network, creates eddy currents that cause electromagnetic field. It is sent to the external winding, which also doubles as the boiler body. This is where the heating of the coolant that flows through the pipes occurs.

The induction unit must have an inlet pipe cold water and comes out hot. Typically, the input is welded to the bottom of the housing and the output to the top. The carrier is fed inside, flows around the body, is heated due to good thermal conductivity and leaves through the upper hole into the heating system. The main difficulty when creating your own boiler is to correctly position the outer winding and core so that the vortex flows and the created field effectively heat the boiler. To do this, it is important to analyze the given diagram, which is understandable to 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 does not settle on the housing either, 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 welds minimal amount, or even not at all. The main disadvantage of an induction heater will be its price, so more and more homemade circuits, we will consider one of them. Also, it cannot be located near the permanent residence of people, because it is a source of EMR, which means that a separate room will be required. far corner Houses.

Assembling a simple induction boiler

The most uncomplicated 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 using these instructions.

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

Step 1: Select an energy converter

At the entrance, electricity will be met. Only very advanced users can make it themselves, since we called this scheme the simplest, we assume that you will simply purchase it at the appropriate store. Which one of those suggested there should I take? This depends on the power you expect to receive from your future induction heater. On average for small suitable for home high-frequency welding inverter 15 A. It is desirable to have a smooth current change function.

Step 2: Heater Body

We won’t make anything complicated inside our boiler; we’ll let the water flow through a heated steel wire. To do this, we take rolled products with a diameter of at least 7 mm. Cut pieces 5 cm long. The quantity is determined by the size of the housing where we will put them. We will make it from a plastic pipe with thick walls; in the future we will wind an induction coil on it. 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 reserve.

Step 3: Induction Coil and Connection

To create a coil you need copper wire, our plastic pipe is evenly wrapped with it. It is enough to make 90–100 turns. It is important to maintain the same space between them. When you have obtained the desired result, step back 10 cm from the outer turns and cut the pipe.

Step 4: Adapters

Now we will organize the supply and exit of 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. At the bottom we attach an inlet adapter through which water will flow. Then we tightly and completely fill the body with wire and close it with the output adapter on top. 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: Connection

The ends of the coil are connected to the inverter, but it’s too early to connect it yet. First, the resulting unit must be embedded into the heating system. To do this, we saw off in suitable place part of the pipeline of such a size that the home-made boiler located in its place will be without gaps. Using adapters we fix the inlet and outlet openings. Now you can connect the coil to the inverter alternating current. All that remains is to let water into the system and turn on our boiler.

What conditions are required for safe operation of the boiler?

Assembling an induction boiler on our own turned out to be not so difficult, but there are several circumstances without which we will not achieve its correct operation. Such a heating unit will not function if your heating system No forced circulation coolant. That is, it must be a closed network with a pump that will drive water along the circuit. You must also 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 extremely important 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.

To the material itself, where the boiler crashes, special requirements No. It can be either plastic or metal. The main thing is that it is a rigid structure and not dangling hoses. Coil location considerations fire safety should be 30 cm from the walls and 80 cm from the floor and ceiling. If there should be some other devices or furniture nearby, then it is also advisable to maintain a distance of about 30 cm from them.

It also wouldn’t hurt to install an automatic valve with a pressure gauge at the boiler outlet so that, if necessary, it relieves the growing pressure, which could cause our body to 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 inputs to allow water to drain 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 eliminate the possibility of accidentally touching the coil, which will cause an electric shock. We would change this recommendation to status mandatory condition.

Energy resources, which are usually used to heat private homes, are constantly rising in price. Heating will help to heat your suburban home without additional expenses. This is the heating method that will allow you to achieve maximum results for little money.

It is not necessary to purchase the device. Any homely owner can make an induction boiler himself. Moreover, this type of home heating can be used 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 operating principle of high-frequency induction boilers allows you to leave the previous room heating system unchanged. This will please those who like to save money. After all, convert the heating into big house will definitely cost a pretty penny. And it took a lot of time. Installing an induction heating boiler with your own hands will not take much time or money. It is accessible 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 you can describe the simplest operating principle. The primary winding of the boiler converts the electric field. The secondary winding directs heat to water, oil, antifreeze, whatever.

Understand schematic diagram induction boiler and even a novice master can bring it to life. Layers underneath the body thermal insulation material, electrical insulation, double wall core, and outer loop. The result of this design is the almost complete absence of heat loss during transfer to the coolant.

Photo of the induction boiler diagram

What makes the high-frequency apparatus so highly effective? The secret is that the coolant is shorter than in conventional systems time - twice as fast - manages to heat up twice. All this is because low level inertia. The financial benefits from such a design are obvious. There is another plus thanks to magnetic field remain clean, without scale.

Other benefits become apparent as you use it induction heating. The period of use of the equipment is not limited in any way. The resulting structure does not require any maintenance, not even cleaning. Wipe off surface dust as much as possible.

Induction boiler device

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

Creating a cheap induction heating system in your home is a simple matter, anyone can do it. Special Education no need to receive. You don't need to study heating theory either. Enough to have on hand necessary tools and source materials to bring the idea to life.

It’s quite possible to do it with your own hands. What will you need for this? Welding inverter - for quick and easy assembly of the housing and connection. Next, you need to select materials that will be heated using an electromagnetic field. Experience shows that the most effective and inexpensive option will become steel wire. With a diameter of no more than 7 mm. It must be cut into pieces no longer than 5 cm.

It is easiest to use an ordinary one as the body of an induction electric boiler, inner diameter 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. This part of the device will heat up. This will become a section of the pipeline with 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 coolant will flow through the adapter into the induction boiler, heat up there, and then heat the entire heating system. Thus, the adapter must be connected to the very base of the boiler body.

The bottom of the plastic case must be lined with a metal mesh. It will become a barrier against falling out of pieces of steel wire. Using short pieces of wire, it is necessary to fill the entire cavity of the pipe. It’s good if the pieces are short, no more than 5 centimeters. This way the pipe will be filled more thoroughly.

Plastic pipe as a body

The induction coil acts as the main heating element in this design. The coil for the boiler must be made from enameled copper wire. It is necessary to wind this copper wire onto the already prepared body of the future electrical device. 90 turns.

An important point: during winding, you need to ensure that the distance between the turns is as uniform as possible. Now the inductor is ready to connect to the heating system.

The result of this work is small size a device that is connected to any part of the heating system. It is only necessary to cut out a piece of the pipeline, and instead of it, 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 coolant: water, antifreeze, oil, and so on. Otherwise, the case will not withstand the heat and will melt.

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

Second type of boiler

There are other ways to create similar heating devices. Let's 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. Welding experience preferred. You will need a three-phase stationary inverter and additional tools.

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

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

Outer pipe winding
