DIY induction water heater diagram

Are you trying to find a new and more effective way to heat the water in your house? The homemade induction water heater is the only option. With this innovative technology, you can get the hot water you need in an economical and environmentally responsible manner. We’ll go over every detail of this do-it-yourself project in this article, from understanding how it operates to making your own diagram for an induction water heater.

Conventional water heaters can be expensive to operate and require a lot of energy. But you can save a lot of money on energy and lessen your carbon footprint by switching to an induction water heater. By using electromagnetic currents, induction heating heats water directly without the need of a large, ineffective heating element. You’ll experience quicker heating times and cheaper energy costs as a result.

The adaptability and versatility of a do-it-yourself induction water heater is one of its biggest benefits. Regardless of whether you’re heating water for residential or commercial use, this technology can be customized to meet your unique requirements. Knowing the basic ideas behind induction heating will enable you to plan and construct a unique water heating system that satisfies your needs.

But what is the precise mechanism of an induction water heater? It all boils down to electromagnetic induction’s power. A magnetic field is created when an electric current flows through a coil of wire. When a conductive object, like a metal water container, is placed in this magnetic field, it causes eddy currents to flow through it. The heat produced by these currents causes the water’s temperature to rise quickly.

Though it might seem difficult at first, making your own DIY induction water heater diagram is completely doable with the correct advice. You can easily build your own induction water heating system by comprehending the essential elements and dissecting the procedure into smaller, more manageable steps. This project offers a satisfying chance to harness the power of induction heating in your own home, regardless of your level of experience with do-it-yourself projects.

Water boiler with transformer

Take out or purchase a cheap welding inverter (transformer) with a current adjustment range of 18 to 25 amperes to get started. Small roller or stainless steel cuts are used as heating elements in water heaters. If a katanka with a diameter of 6–8 mm is used, the wire is cut into pieces that range in length from 3.8 to 5.5 cm. Next, a 45–50 mm diameter plastic pipe with thick walls is used to construct a heater housing. This pipe segment’s free open end of the case chopped wire is where one end is sealed with a tiny, cellular mesh.

They start to create an inductor coil by filling the pipe with trimming all the way to the top. Wrap the created corps with a minimum of 1.5 to 2 mm of enameled copper wire. The welding inductor’s amperage determines the number of turns, which ranges from 85 to 95. The coil (pipe with trimming) is positioned in the middle of the casing. Adapters are used to connect the heater to the heating network or water supply system.

In order to create an induction boiler using the resulting heater, you must cook using two pipes that have a bagel-like design. This is a water heating element. Choose a suitable diameter tank and place the input and output water pipes in the upper portion of the tank. This case contains an earlier-made induction coil. Next, fasten the heater (bagel) to the nozzles so that it strictly passes through the center of the inductor. The coil’s isolated ends are connected to the transformer. The water heater has a heat-insulating screen covering it to prevent heat loss.

Water heats up as it travels through the pipes inside the coil and emerges from the output pipe hot.

It is important to keep in mind that this type of boiler can be utilized in closed heating systems that circulate water via a pump.

One can connect such an induction boiler water heater to a plastic pipe system. The boiler is installed 80–90 cm from the floor, ceiling, and wall, and 30–40 cm from the wall to ensure safety. For system discharge, this water heater needs to have a valve installed on the pipe. By installing a heating radiator, a boiler akin to this one can be used as a heater in a small space.

Electronic variant

The second DIY induction heater type makes use of the advancements in contemporary electronics.

The suggested system for autonomous assembly starts operating right away after assembly and doesn’t require any configuration. With a somewhat higher power, this electronic circuit operates on the consistent resonance principle. By utilizing more potent field keys and capacious capacitors, you can raise the heater’s output power considerably.

We first remove the throttle from the computer power supply before assembling the circuit. We wrap a 1.5 mm caliber wire on a powder iron ring in 10 to 30 turns. Based on the open transition’s maximum resistance, select field transistors. These devices belong to the IRF740 series in our instance, though IRFP250 can also be used. We use diodes like UF4007 or Her305 that have a reverse voltage of at least 500 V and a current of at least 3–4 A. Zener diodes, which have a maximum capacity of 2-3 watts, are used at 15–18 V. 0.5 watts are used with resistors.

Gather the schematic and construct an induction coil. It has six to seven 1.5 mm turns of wire. We incorporate it and fasten it to the completed electronic circuit. A heater of this kind can reach M6 yellow temperature. Although this scheme is rather straightforward, transistors can be harmed by heat released during installation operation. They must therefore be mounted on radiators.

The physical principles of the water heater on induction current and how to assemble it with your own hands

An innovative substitute method for heating residential spaces is the induction water heater. The fundamental purpose of induction energy is to lay the foundation for reasonable use. He doesn’t produce soot, is completely safe, friendly to the environment, and doesn’t require the collection of firewood or coal. The individual heating system’s water is successfully heated by the induction thermal generator. Apart from being able to buy a factory-made boiler from the retail network, you can also complete the task yourself. which will result in a gradually discernible savings for the family spending plan.

• 1 principle of induction heating
• 2 structural features and work of thermal generator

• 2.1 principle of operation of the system

The principle of induction heating

An example of how well the water heater works with induction current that you made yourself

The electromagnetic field’s energy is the basis for the induction heater’s operation; the coolant takes over and transforms it into heat. This heater’s inductor, which is represented by a multi-pin cylindrical coil, creates the magnetic field. An alternating magnetic field is produced by an alternating electric current flowing close to this coil.

When this electric field moves, its lines, which are perpendicular to the direction of the magnetic flux, create a vicious circle. Heat is produced when electrical energy is transformed into vortex flows by alternating current. Consequently, the heated object receives contactless transfer of the inductor’s electricity.

Even at low heating speeds, induction heating uses thermal energy very efficiently. As a result, an induction water heater that you build yourself heats water quickly to noticeably high temperature indicators.

Structural features and work of thermal generator

As an induction heater for this system, you can set up individual heating by using a transformer with two windings:

1. Primary.
2. Secondary short -closed.

Here, the internal component forms vortex streams. They point the electric field that is created at the secondary circuit. He serves as the coolant’s body as well as its heating element at the same time. The entire surface heats up first, followed by the entire element, as the density of vortex currents directed toward the core increases.

An illustration of how to install a water heater that uses induction current to heat

Two pipes are provided by induction boilers to supply the heated coolant’s output as well as cold water.

If someone wishes to construct this equipment by hand, keep in mind that:

• The lower pipe is mounted on the introductory main section;
• Upper – on the supply section of the pipeline.

The principle of operation of the system

The coolant flowing through the heating system transfers the heat produced by the boiler. The general heating system receives heated water directly through the supply pipe because of hydrostatic pressure, and this water is continuously released because coolant is discharged into it. As a result, there is absolutely no chance that the equipment will overheat here.

Comparing the induction water heater’s energy usage to that of other models

The induction system’s continuous vibration prevents scale and its hard deposits from building up on the pipeline’s interior walls. Since induction heaters lack conventional electric heating elements, there is absolutely no chance that they will experience costly malfunctions. Furthermore, there are no removable connections that can cause unpleasant leaks that are not anticipated. This boiler’s ability to operate quietly makes it a good choice for installation in any residential setting.

Self -manufacture of the structure of the induction heater

It is not hard to make an induction water heater on your own. This is a task that even a relatively beginning master can accomplish with success. In order to do this work, you must first have:

• Inexpensive high -frequency inverter from the welding machine, so as not to bother with the manufacture of such a complex unit on their own;
• A thick -walled piece of a plastic pipe, which will become a heater body;
• Steel stainless wire or rollege of not more than 7mm in diameter, which is the basis for heated material in an electric field;
• Adapters for connecting the main body of the water heater to the individual heating system;
• A metal mesh that should hold steel pieces of wire inside the housing;
• Copper enameled wire for creating an induction coil;
• Picking for cutting rollers or stainless steel;
• Water supply pump.

The main technological stages of work

The following fundamental guidelines must be understood and followed when setting up the induction water heating system:

1. The welding current of a high -frequency inverter for the heater must correspond to its power. Its optimal value varies from 15 amperes or higher, if necessary.
2. For heating materials in a high -frequency field, you need to use five -centimeter segments of steel rocket or stainless wire. To do this, the prepared wire must be cut with bites, adhering to these sizes.
3. The case of the induction heater should be made of thick -walled plastic pipe, the inner diameter of which should be at least 5 centimeters similarly to the length of the cut wire.
4. The adapter is attached to one side of this plastic pipe, which should connect this design to the heating system.
5. A metal grid is laid on the bottom of the plastic pipe with your own hands, which prevents the fault.
6. The chopped pieces of metal wire are tightly filled inside the pipe from the plastic so that there is no free space.
7. The second end of the pipe is equipped with another transitional element.
8. For the manufacture of an induction coil, this plastic pipe is wrapped with a prepared copper enameled wire. The number of turns in the winding should be minimal 80, and the maximum 90.
9. Then the device is connected to an individual heating system, water is poured, an inverter is connected to the manufactured winding.
10. For forced circulation of the coolant, the pump is built into the heating system.
11. To ensure regulation of water temperature in automatic mode, a thermostat is connected in the rupture of the main power of the induction inverter.

Conclusion

A closed individual heating system with a plastic pipeline is fitted with induction heaters. For safety, it is advised to install a set of components after the output pipe, which is represented by:

• Manometer;
• Subversive valve;
• Automatic air removal device.

At first, making an induction water heater by hand could seem complicated and time-consuming. But then, it will only help the family budget by drastically lowering the price of pricey electricity. Because of the structural characteristics of this device, the coolant heats up considerably more quickly than electric heaters that operate on an equivalent amount of electricity.

These days, some artisans use an electromagnetic transformer—which is built around two strong transistors—to create an induction heater. Its induction heating is accomplished by subjecting it to the metal of the fuko currents.

This equipment operates without separating harmful fuel degradation or combustion products, which improves the condition of the surrounding atmosphere. For every family, the proper setup of the heating system with an induction water heater is an unquestionably cost-effective choice with flawless 25-year workmanship.

How to make an induction heater with your own hands

Here you will find out:

An induction water heater is the most cost-effective and contemporary water heating device. In contrast to analogs, it satisfies current safety regulations, is entirely environmentally friendly, and doesn’t dry out or burn the air. Has the ability to function as a boiler to heat the space as well as a flow water heater. While most people purchase the device from a store, we provide an alternative: independent manufacture. In the latter scenario, the gadget will be significantly less expensive even though it might not look as nice.

Pros and cons of induction devices for heating water

The gadget is reasonably easy to use and install; no special paperwork is needed for use or installation. The water heater offers the user the best dependability and a high level of efficiency. Since convection causes water to move through pipes when heated, you cannot even install a pump when using it as a boiler for heating (the liquid practically turns into steam).

In addition, the device offers several benefits that set it apart from other kinds of water heaters. The induction heater, then:

Induction heaters work by heating the water through the pipe it flows through, which is heated by the induction current generated by the coil.

• much cheaper than your analogues, such a device can be assembled without problems yourself;
• completely silent (although the coil vibrates during work, but this vibration is not noticeable for humans);
• It vibrates during work, so that dirt and scale does not stick to its walls, therefore it does not need cleaning;
• It has a heat generator, which can be easily made tight due to the principle of operation: the coolant is inside the heating element and the energy is transmitted to the heater through an electromagnetic field, no contacts are needed; Therefore, sealing gums, seals and other elements that can quickly deteriorate or flow;
• There is simply nothing to break in the heat generator, since the water pipe is heated, which is unable to deteriorate or burn out, unlike Ten;

Remember that induction heater maintenance is significantly less expensive than that of a boiler or gas boiler. There are very few parts in the device that break almost never.

The induction water heater has a lot of benefits, but it also has some drawbacks.

• The first and most painful for the owners is an account for electricity; The device cannot be called economical, so you will have to lay out a decent amount of once for its use;
• The second – the device is very hot and heats not only itself, but also the surrounding space, so it is better not to touch the body of the heat generator during its operation;
• Third – the device has extremely high efficiency and heat transfer, therefore, when using it Be sure to set the temperature sensor, otherwise the system may explode .

DIY induction water heater: Scheme

The apparatus is a transformer that has primary and secondary windings. Induction heating is produced by the first circuit, which transforms electrical energy into vortex currents and a directed induction field. The converted energy is passed to the coolant (in our case, water) on the secondary circuit.

It is crucial to take into account the kind of material used to make the winding. Therefore, a copper wire is typically used in household models. This kind of material works well for boiler water heating.

A generator and optional pump are also included in the device in addition to the transformer.

Diagram showing the basic induction water heater. As you can see, there aren’t many parts in the device and its design is rather straightforward.

Nodes and parts of the heat generator

The apparatus consists of:

• AC generator that increases current frequency;
• The inducer that transforms electricity into magnetic energy is a coil of copper wire;
• Heating element, most often its role is played by a metal pipe.

This design makes it possible to transmit energy virtually losslessly. 98% efficiency is attained.

Principle of operation

The generator, coil, and core of the induction water heater are made of electromagnetic energy, which causes the core to heat up.

Electromagnetic energy is produced by the device from electrical energy. The latter then has an impact on the core, or pipe, which warms up and gives the water thermal energy. All these energies are converted by the inducer, which consists of a coil and core. Since it is difficult to achieve high heating at the standard frequency of 50 Hz, the generator is used to increase the current frequency.

The current frequency in factory models is up to 1 kHz.

DIY flowing induction water heater

Gather all the information you’ll need before beginning the installation. Therefore, the best choice would be a high-frequency inverter for welding that smoothly changes the current strength range. The cost of such a device will be lower. A three-phase transformer, which supplies alternating current to the water heater inductor, is a more costly option. In this instance, it makes sense to use a coil with 50–90 turns and a copper wire that is at least 3 millimeters in diameter.

You can use a wire (used as a heating element) and a metal or polymer pipe as a core. To calmly withstand high temperatures in the latter scenario, the wall thickness should not be less than 3 mm.

Bite size tools, screwdrivers, a soldering iron, and a welding machine (if a metal pipe is being used) are required for assembling the water heater.

Installation of an induction heater in water

Using a copper wire, wrap the pipe in approximately 90 turns.

The device can be assembled in a variety of ways. We advise attempting to put the gadget together using the following blueprint:

1. Prepare the workplace, materials and tools.
2. Fix a small segment of the polymer pipe (do not forget that the minimum wall thickness should be 3 mm).
3. Cut the ends of the core so that 10 cm remains in the reserve wires for taps.
4. Mount the corner on the lower bouncer. In the future, the return from heating should be connected here (if the heater is used as a boiler).
5. Place the chopped wire around the pipe tightly. It is necessary to make at least 90 turns.
6. Install a tee on the upper pipe through which hot water will exit.
7. Mount the protective contour of the device. It can be made both from the polymer and from the metal.
8. Connect a copper wire to the water heater terminals, then fill the core with water.
9. Check the operating capacity of the inductor.

Recommendations. In conclusion, installing ball valves will make it easier and more convenient to disassemble the water heater in the event of a breakdown. However, since this does not produce the desired effect, it is not necessary to fill the pipe with metal fragments. Remember to keep the window in the case so you can access the control panel of the welding machine.

Water induction heaters for heating

Heating circuit in which the coolant is heated by an induction boiler.

Such a device has demonstrated its efficacy as both a heating boiler and a running water heater. It is true that in this instance, the welding machine cannot function as a generator and will instead require the use of a transformer with two windings. The electromagnetic field generated on the secondary circuit is transformed by the latter from the vortex currents that occur on the primary winding.

In addition to water, coolants for heating systems can also include oil or antifreeze. In other words, any liquid that has the ability to conduct electricity.

Two rods for hot and cold water must be installed in an induction water heater’s boiler. A pipe that will supply hot water to the heating system must be installed on top of the cold water pipe, which will come from the bottom and be mounted on the line’s introductory section. Therefore, without the use of a pump, water circulation occurs naturally as a result of convection.

Are you trying to find a cost-effective way to heat water? A do-it-yourself induction water heater is the only option. This creative system heats water without direct contact, producing quick and energy-efficient heating, by utilizing electromagnetic induction. Simple parts like a coil, power supply, and control circuit make up the setup, making it doable for do-it-yourself enthusiasts. In addition to providing an affordable option for heating water, this system uses less energy than conventional techniques. Building your own induction water heater is a useful and satisfying project for any homeowner, regardless of whether you want to reduce your utility costs or are just looking for a greener option.

What you need to know about security

Remember that we are working with an electric heating device, which poses a greater risk. As such, you need to adhere to certain guidelines when assembling and operating it.

When connecting an induction boiler, make sure it has a security group installed and is connected via a separate electric line.

1. If in the boiler water circulation is carried out naturally, then be sure to equip it with a temperature sensor so that when overheating, the device will turn off automatically.
2. Do not connect a home -made water heater to a socket, it is better to conduct a separate line with an increased cable cross -section.
3. All open sections of the wires need to be insulated to protect people from shock or burns.
4. In no case do not turn on the inductor if the pipe is not filled with water. Otherwise, the pipe will melt, and the device will close it or it may even light up.
5. The device must be mounted at an altitude of 80 cm from the floor, but so that about 30 cm remains to the ceiling. It is also not worth installing it in the residential area, since the electromagnetic field does not affect people"s health well.
6. Do not forget to make the inductor ground.
7. Be sure to connect the device via the machine so that in the event of an accident the latter turns off the power supply from the water heater.
8. In the pipeline system you need to mount the safety valve, which will reduce the pressure in the system automatically.

You can increase the efficiency of your home’s heating system at a reasonable cost and with great satisfaction by building your own DIY induction water heater. Using electromagnetic induction, you can heat water more effectively than with conventional techniques, ultimately saving money and energy.

The simplicity and dependability of an induction water heater are two of its main benefits. Even people with little technical knowledge can effectively assemble and install their own system if they have the correct parts and a well-designed schematic. It is a well-liked option for homeowners trying to cut back on their energy costs and carbon footprint without going over budget because of its accessibility.

In addition, DIY induction water heaters provide a wide range of customization options. You can modify the system’s features, power output, and size to meet the needs of your home, based on your individual requirements and preferences. The adaptability of DIY induction heaters makes them a viable choice for a range of scenarios, whether your goal is to augment your current heating setup or find a stand-alone solution.

When building an induction water heater, safety should always come first, just like with any do-it-yourself project. Make sure you closely adhere to all instructions, handle electrical components with caution, and seek advice from qualified professionals if you have any questions about any step of the procedure. You can take comfort in the advantages of your DIY heater by putting safety first.

In conclusion, do-it-yourself induction water heaters provide an affordable, effective, and adaptable way to improve your home’s heating capacity. You may make an affordable and green substitute for conventional water heating techniques with the correct supplies, advice, and attention to safety. Building your own induction water heater is a worthwhile endeavor, regardless of whether you’re motivated by sustainability, cost savings, or just the satisfaction of a well-executed do-it-yourself project.
