Do-it-yourself powerful induction boiler. Induction heating boilers: how to make it yourself. Examples of homemade designs

Induction water heaters are good because they consume the least amount of electricity compared to other options for electric heating boilers. However, not everyone can afford such a pleasure, especially for use in summer cottages that are rarely visited. This is due to the high price of the products, which can vary from 25 to 100 thousand rubles. In order to still please yourself with such an electric heater and at the same time save your own money, we recommend making an induction boiler with your own hands. Read on to learn how to assemble it at home!

Idea #1 – Simple Vortex Heater

First of all, familiarize yourself with how this heating option works and what are its advantages over alternative options boilers The video below will answer all your questions!

Description of the advantages and operating principle of induction water heaters

The materials you will need to make your homemade product are:

Plastic pipe with an internal diameter of no more than 50 mm.
Steel wire with a diameter of no more than 7 mm.
2 adapters for connecting to heating system(pipes).
Metal mesh with small cells.
Copper enameled wire.
High frequency inverter.
Insulating material.

Having prepared all the materials, you can proceed to assembling the induction boiler with your own hands. First of all, cut the steel wire into 5-centimeter pieces. After this, cover one side of the plastic pipe with a mesh and pour the cut wire inside. The amount of material should be such that the volume of the homemade product is completely “clogged” with wire. Then the second end closes metal mesh, which will prevent the wire from spreading throughout the heating system.

When the filling is prepared, you need to independently make the connection points for the homemade vortex boiler to the heating main. To do this, adapters are secured on both sides of the pipe by welding or threaded connections.

Next, you need to make the heating element of the device yourself - an induction coil. All you need to do is wind about 90-100 turns of copper wire over the pipe. Be sure to keep the pitch between turns so that your homemade induction boiler works evenly. Once completely wound, the ends of the copper wire are connected to the inverter and eventually the boiler body can be assembled and insulated with suitable thermal and electrical conductive material.

Launch homemade heater must be done only after connecting to the coolant - water. If you turn on the inverter without water in the housing, the pipe will instantly melt and all your efforts will be in vain.

That's all the instructions that allow you to make an induction boiler from improvised materials at home. This homemade product can be installed on any part of the heating system, but due to its not very attractive appearance, we recommend hiding it out of sight.

You can clearly see the principle of operation of the device in this photo:

As you can see, the core inside is red-hot, which is due to the influence of the electromagnetic field. We recommend viewing the tests of the assembled device in a video example:

Effect of electromagnetic field

Idea No. 2 – A more powerful device

To make a powerful induction boiler with your own hands, you just need to know how to use welding. In fact, the assembly technology is not too complicated and any self-taught electrician can handle it, as you will see after reading.

So, the materials you will need are:

two pieces of metal pipe of different diameters;
enameled copper wire;
two adapters for heating pipes (for supply and return);
heat-insulating casing;
three-phase inverter.

A drawing of a homemade heater looks like this:

As you can see, one pipe needs to be welded inside the other to create a hollow tank in the form of a cylinder. Also, using a welding machine, you need to “embed” two pipes into the supply container cold water and hot output to the heating system.

Next, as shown in the diagram above, you need to wind the copper wire around the body of the induction boiler. The winding, as you understand, will serve as a heating element and, in contact with the coolant, will heat it. It is necessary to stretch a heat-insulating cover over the created structure, then open the water supply and test the system.

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 both in large country houses and in small ones. 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 simplest principle work. The primary winding of the boiler converts 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

Due to what this appears high efficiency high frequency apparatus? The secret is that the coolant manages to heat up twice in a shorter time than in conventional systems - twice as fast. All this is due to the low level of inertia. The financial benefits from such a design are obvious. There is another plus, thanks to the magnetic field, they remain clean and free of scale.

As you use it, other advantages of induction heating become apparent. 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. You do not need to receive any special education. 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.

As the body of an induction electric boiler, it is easiest to use an ordinary one, the internal 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. 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 a small 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 a light weight devices. Nozzles are used to supply coolant.

Outer pipe winding

Advantages

When making induction boilers yourself, you must follow some rules.

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

Care must be taken to ensure that the distance between the induction electric boiler and other objects (furniture, household appliances) was at least 30 cm. To avoid damage to property. You should also 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. Without any additional maintenance.

Photo of the induction boiler connection diagram

Advantages of induction boilers:

the use of both alternating and direct current is allowed;
all elements of the device are durable;
elementary design;
there is no need to allocate a special place for the boiler room;
Class fire safety 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 self-production minimum costs required.

It is obvious that the induction type is a modern device that has all the qualities of the technology of the future. A highly efficient, low-cost unit that can quickly heat and country cottage, and the dacha, and warehouse space. There are no installation difficulties. And no maintenance costs.

Unprecedented savings, super efficiency, incredible service life and even new principle energy transfer. This is how sellers of induction boilers characterize their products. It's time for us to join high technology future and find out if it really is so beautiful, this induction heating.

Induction heating, flies and cutlets

Our task in this article is to separate flies from cutlets, advertising tricks of marketers from the harsh truth of life. Let's start with the fact that the expression “induction heating”, which has become popular on the popular Internet, and which we deliberately included in the title of the article, is nonsense. We will, of course, be talking about electric induction water heaters, which are used in conventional water heating systems. We'll try to give them objective assessment, to tell about real advantages and the disadvantages of these heating devices are still quite new for our market.

How does an induction water heater work?

Especially for those who counted crows in 9th grade physics lessons:

Video for inquisitive dummies: what is electromagnetic induction in simple words

Structurally, the water heating part of an induction boiler is similar to a transformer. The first, outer circuit is the winding coils connected to the power source. The second, internal one is a heat exchange device in which the coolant circulates. When voltage is applied, the coil generates an alternating magnetic field, as a result of which currents are induced in the heat exchanger, causing it to heat up. From metal thermal energy transferred to water or non-freezing liquid.

The design of an induction water heater is as simple as five cents. In this regard, craftsmen who have access to cheap components assemble induction heating with their own hands at home. For those who are not sufficiently familiar with safety precautions in the energy sector, we do not recommend repeating their experience: the voltage is high, it is dangerous!

The operation of kitchen induction cookers is based on the same principle, only the cookware itself, which must be made of a specially selected metal, serves as the secondary circuit. Such electric stoves are two times more economical than conventional “pancakes” due to the fact that there are no losses in the transfer of thermal energy from heating elements to pots and pans. High efficiency of such kitchen appliances attracts citizens so much that topics like “heating using an induction stove” are seriously discussed on forums. And some of our readers ask the question of how to organize heating induction hob private house. We answer: theoretically, this is even possible, but it is extremely inconvenient: you will have to constantly run and add water to the pan so that it does not boil over. In addition, only the kitchen will heat up, there will be a lot of steam, it’s a pity for the dishes.

In order for a water heater to turn into a full-fledged heating boiler, it must be equipped with control devices that allow it to maintain the temperature of the coolant at a given level. Many manufacturers of induction boilers offer simple automation, but a competent electrician can assemble the circuit himself.

Same for 380 V

Who invented it

Let's leave aside those sellers who talk about the “new principle of energy transfer”, which is supposedly used in induction boilers. These people are blatantly illiterate or lie shamelessly, looking at customers with innocent eyes. Let's see how much innovation there is in this device and who can be considered its creator.

The honor of discovering electromagnetic induction belongs to Michael Faraday, which happened in 1831. Inductive heaters went beyond laboratories in 1900, when the first industrial induction steelmaking furnace was launched in Sweden. Since then and to this day, such heaters and furnaces have been widely used in production, but until recently they were not used for heating. Of course, well-known heating equipment manufacturing companies explored the possibility of heating the coolant using electromagnetic induction, but the use of this technology was considered inappropriate. So small domestic enterprises that have established small-scale production of such devices are “ahead of the rest.” But we can confidently say: the inductive heating boiler does not contain any new technical ideas.

How economical is a super-economical boiler?

To begin with, let's say that heating with electricity is initially the most expensive. In terms of cost, electric heating cannot compete not only with cheap natural gas and solid fuel, but even with liquefied gas and diesel fuel. The only way to reduce costs is to install a heat accumulator in the house and heat it mainly at night, when a preferential electricity tariff is in effect.

To put it simply, a heat accumulator is a large, well-insulated reservoir of liquid, which during the day will store reserves of “cheap” night energy

Sellers claim that induction water heaters for heating have a fantastically high efficiency of 100%. And this is the honest truth. However, it should be noted that all heating units have exactly the same efficiency. electrical devices, regardless of their type. The consumed electrical power is completely converted into thermal power. However, it should be taken into account that not all the energy is transferred to the coolant; part of it from the heat exchanger is dissipated in the boiler room. Which, in general, is not a problem, because the furnace room should also be warm. But in conventional electric boilers, the heating element is completely immersed in liquid and the energy of the heating element is used more fully.

If we delve deeper into the topic of saving, it should be said that the most economical view Electric heating is provided by warm cable or film floors. Greater efficiency is achieved due to optimal temperature distribution in the room and the absence of work losses mechanical devices. Unlike water heating, there are no circulation pumps.

With heated floors, the temperature in the room is distributed optimally: your feet are warm, your head is cold. Radiators give the opposite picture. In the room with warm floors you can maintain a lower average temperature (and spend less energy), while a person will feel even more comfortable than usual

Conclusion: in terms of efficiency, an induction water heater is no better or worse than other electrical appliances intended for heating, and has standard characteristics.

How long will an induction heating boiler last?

Manufacturers claim that an induction boiler will last at least a quarter of a century. And this may well turn out to be true. There are no moving parts in the device, there is no mechanical wear. If the copper winding and coil are made properly, they can last for many decades. The coolant core will be constantly subject to erosion from the coolant, but, being made of good steel and having sufficient thickness, it is also capable of working for a very long time. Is it true, prerequisite The “longevity” of a water heater is its operation in the recommended temperature conditions, and automation is responsible for this. We can say that an induction boiler can potentially serve its owners without breakdowns much longer than other types of heat generators for heating, and real numbers depend only on the level of quality at which it is manufactured. We have been producing and installing such water heaters not so long ago, so long-term statistics on the equipment have not yet been developed.

Conventional electric boilers cannot boast of such reliability. With constant use, the heating element or anode will last 10-15 years. They are easy to replace, but they are an additional expense and hassle.

A variant of a heating scheme for a private house based on an induction boiler. 1 – cabinet with automatic control and protection; 2 – induction water heater; 3 – hydraulic safety block (pressure gauge, valves); 4 – shut-off valves; 5 - circulation pump; 6 – filter; 7 – membrane expansion tank; 8 – heating circuit; 9 – make-up and drain line

To buy or not

So, does it make sense to purchase an induction boiler for heating? Alas, we cannot give a definite answer to this question. Stories about its super-efficiency turned out to be a myth; reliability can be high. It may not be. The noiselessness they are talking about is inherent in all electric heaters; the sound can be produced by a pump. Compactness is highly controversial.

At first glance, the induction boiler (right) is much more compact than the heating element boiler (left). However, in the body of the latter there is a bunch of stuff necessary equipment, which will be needed for induction too. And it’s not a fact that if placed randomly, it won’t take up space on the wall. more space

Otherwise, we do not see any advantages for an induction boiler over conventional ones. But there is a drawback: it costs more. Or, to be more precise, they ask for more money. Moreover, a good heating element boiler for its money is a balanced device, completely ready for installation and operation. And the induction heater still needs to be completed additional equipment. In our opinion, marketers and sellers, by presenting us with an ordinary product as an exclusive, are trying to “skim the chips.” Get more profit than on other products. Although, a downward trend in prices has already emerged and we can expect that fair prices will be established for induction boilers over the next few years. Or they will simply stop producing them.

If you are considering purchasing an induction water heater for heating own home, we recommend communicating with professional heating engineers, both designers and practitioners. Experienced specialists monitor trends and have the opportunity to give assessments on new types of technology based on their own practical experience. Equipment suppliers are also worth listening to, but what they say should be taken with a critical eye.

Video: induction boiler

In the process of planning the installation of a heating system at the dacha or in 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 design is such that it allows you to do without harmful emissions in 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 look at what an induction heating boiler is: everything about the operating principle + 2 do-it-yourself device options. In addition, its advantages over conventional electric boilers and gas units.

Construction of induction boilers

The basis internal structure such a boiler has an inductor (transformer) turned on. Conventional household induction boilers are slightly different from similar industrial ones with a cylindrical winding system. Compact boilers for domestic use use toroidal copper windings.

The outer casing of the unit is made of painted metal, then there is a thick layer of thermal and electrical insulation, inside of 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 on the core is the primary winding. It is in it that the energy of the electric field is converted into a magnetic one, 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 influence of this energy, releases a large amount of heat that is transferred to the coolant. Toroidal winding allows you to create units with low weight and dimensions.

Operating principle of induction boilers

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

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

The heat produced is transferred to the coolant circulating inside the circuit. Rapid heating of the liquid creates convection currents. This means that the heated coolant expands greatly and rushes up the boiler structure and further into the heating system itself. Often this is enough for it to happen full-time job domestic boiler with an average length heating circuit. This method allows you to quickly heat the entire system, but for better circulation you need to additionally install a conventional circulation pump.

Thanks 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 happens because the eddy currents force the core to vibrate, preventing scale from forming. At the same time, bubbles boiling near its body clean the surface of the core. Due to the tightness of the entire system, the coolant absorbs the maximum (98%) amount of released thermal energy. Thus, these parameters greatly increase the efficiency of the boiler, which in a positive way affects its efficiency and service life.

Pros and cons of induction boilers

Induction boilers have a number of undoubted advantages over conventional boilers using heating elements:

Stable efficiency indicators up to 99% for almost the entire service life.
There are no heating elements, which significantly extends the life of the device.
There are no moving elements, which completely eliminates mechanical wear and the need to replace components.
Lack of detachable internal connections does not allow leakage to occur.
Full availability of work even with DC or low voltage in the network.
Very fast heating to the desired coolant temperature (5 – 7 minutes).
A fairly high degree of electrical and fire safety, corresponding to class II due to the use of a core not directly connected to the inductor.
There is no need to install a chimney or provide a separate room for the boiler. To install this system there is no need to attract highly qualified specialists.
The standard service life of the device is up to 25 years or even more. It directly depends on the tightness of the sealed external seam and on the large thickness metal pipes for the core. It does not require any maintenance work during its entire service life.
The boiler can use all available coolant fluids: oil, water, antifreeze, ethylene glycol without any preliminary preparation.
The coolant can only be changed once every 10 years.
Good protection against overheating and various accidents, quiet operation.
The boilers are equipped with electronic automated systems management.
There is no scale inside the circuit.
Possibility of connecting the boiler to any heating systems closed type.
The minimum possible heating of the coolant is 35°C.

But induction boilers have disadvantages, like others heating devices, and according to individual specific parameters.

Such boilers can only be connected to a closed heating circuit, very often with forced circulation of coolant
Quite a large weight of the boiler with quite small sizes. 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 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 range. They have no effect on human body, but they are well sensed by pets and electronic equipment.

Installation of an induction boiler and its control system

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

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

The weight of the mounted boiler is quite serious, so the fastenings need to be given the utmost attention. Special attention. They must be very reliable, taking into account the fact that when the boiler is operating, its weight will increase significantly due to the coolant entering inside. The lateral distance from the boiler to surrounding objects and walls is 300 mm. The distance to the floor and ceiling is 800 mm and no less. An important and mandatory condition for installing 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 next to the outlet pipe: a blast valve, a pressure gauge, an air vent. The expansion tank is installed at a convenient location in the return pipe of the system. Shut-off valves are mainly installed after the safety group.

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 Electrical Installation Code, diagrams and conditions contained in the technical data sheet included in the kit.

Examples of homemade designs

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

First option

To implement it you will need pieces of plastic pipes and welding inverter. Having basic knowledge of physics and knowing how to use wire cutters, you can independently make a basic induction model. To do this, you need to purchase an already created high-frequency welding inverter with continuously adjustable current power up to 15 amperes or even higher. For heating 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 act as a heated element. Their length is about 50 mm, with a diameter of 7 mm.

An important component is copper wire, which can be easily purchased at any specialty store. Do not use windings from old coils. The housing, 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 internal diameter should be 50 mm. Two outlet pipes are attached to this housing for the flow of cold coolant and the release of hot coolant. All inner space the housings 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: an enamel-coated copper wire is gradually wound around a previously prepared plastic pipe. It will take approximately 90 turns. The result homemade device needs to be connected to the pipeline network. A small section of pipe is cut out of the pipeline, and a homemade induction boiler is installed in its place. It is connected through an inverter and the water is simply turned on.

Second option

This option involves the use of a three-phase transformer with the possibility of fixation. In addition, you will also need a welding machine. To make the device, you need to weld two pipes so that they look like a donut in cross-section. This design performs both conductive and heating functions. Then they wind the winding directly onto the boiler body in order to make it more efficient work, despite its low weight and size. A standard coolant heating scheme is used here: it receives a large amount of thermal energy upon contact with the winding.

The manufacturing scheme for this design is somewhat more complicated than in the first version. The boiler is equipped with two pipes, both for the entrance of the cold coolant and for the exit of the heated one. If you come up with it and build it yourself protective cover, then heat losses can be minimized.

Features of self-installation and operation of homemade boilers

As in the case of factory-made boilers, only a closed-type heating system can be suitable for installing a homemade induction installation. It should include centrifugal pump, which creates constant circulation of coolant inside the heating system. The plastic pipelines that are common today are ideally suited for installing a homemade induction boiler. All regulations relating to the installation of shop boilers must be complied with fully and in this case. If you install controls and safety devices on the system, then your homemade installation will be little inferior to its factory counterparts.

Although it is quite difficult to make such a device, and it is better not to take on this task without having “direct hands”, it is a pleasure to operate it. After all, along with ease of use, we also get serious energy savings.

Do you want to furnish your home with efficient and at the same time cost-effective heating? 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 in question is based on the use of inductive 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.

Thus, the internal winding is responsible for converting incoming electrical energy into special eddy currents. An electric field is formed in the unit, which subsequently enters the secondary coil. The latter simultaneously performs the functions of the 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, antifreeze liquids or clean water are used as coolant in such installations.

The internal winding of the heater is exposed to electricity. As a result, some voltage appears and eddy currents are formed. The created energy is transferred to the secondary winding, after which the core begins to heat up. Once the entire surface has been heated, the coolant will begin to provide 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 efforts to correctly assemble a high-quality unit.

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

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

You are not given any extremely complex tasks, 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 difficult-to-use tools or 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 the stainless steel wire or rod into pieces about 5 cm long. The required diameter of the wire used is 7-8 mm.

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

Third step. Cover the bottom of the main pipe with fine mesh wire mesh. Select a mesh with such cells that pieces of loaded stainless steel or wire rod cannot pass through them.

Fourth step. Completely fill the housing with wire or rod, and then cover the free hole in 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 body.

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

As a result of such simple manipulations, you will receive an inexpensive and extremely easy-to-assemble device for efficient heating. The advantage of using a homemade 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 in its place.

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 down the drain.

Be sure to reliably ground your homemade heating device.

Design of a vortex induction heating unit

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

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

A homemade vortex induction boiler operates in almost silent mode. This allows you to mount it in any desired location. There are also no harmful exhausts, so you don’t have to worry about the need to arrange a reliable boiler room and install a chimney.

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

Second step. Place the resulting circle in a plastic pipe of a suitable size.

Third step. Make a winding on a plastic case from materials already familiar to you. 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 case. It will prevent possible leaks electric current and will contribute to a significant reduction in heat loss.

Heating will be carried out due to the contact of the coolant with the same winding. Winding and all further actions are performed according to the same scheme as in the case of an ordinary induction installation discussed in the previous instructions.

Important notes on 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 a few things: important rules, namely:

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

Thus, from inexpensive materials With the help of simple 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 warmth in your own home.

Good luck!
