How to make an induction heating boiler with your own hands manufacturing a home -made heat generator

For your comfort and wellbeing, it is imperative that you keep your house warm during the winter. Although conventional heating techniques, such as gas or electric boilers, are widely employed, interest in more environmentally friendly and alternative options is growing. One such alternative is the use of induction heating boilers, which provide effective heating without requiring fossil fuels. This post will explain how to make your own induction heating boiler at home, which is a cost-effective way to maintain a warm home.

The electromagnetic induction principle, which produces heat by passing an electric current through a coil, is the basis for induction heating. Induction boilers use electricity to create a magnetic field, which heats the water or air in the system, in contrast to conventional boilers, which rely on burning fuel to produce heat. Because of its high efficiency and low waste output, this process is a popular option for homeowners who care about the environment.

Although building your own induction heating boiler may seem like a difficult undertaking, it is completely doable with the correct resources and advice. Using your creative DIY skills, you can tailor the system to meet your unique requirements and reduce installation costs. An induction boiler can be customized to meet a range of heating needs, from producing warm air for your home to heating water for your radiators.

Knowing the essential parts of an induction heating system is essential before beginning construction. An induction coil, a heat exchanger, and a power supply are common components of a system. Standard household electricity is transformed into the high-frequency alternating current required for induction heating by the power supply unit. It is the induction coil that produces the electromagnetic field; it is typically constructed of copper tubing. In the end, the heat exchanger moves the heat from the coil to the water or air that is heated in your house.

The most important thing to consider when building a homemade induction heating boiler is safety. It’s important to follow instructions carefully and take the necessary precautions when working with electricity because it can be dangerous. Ensure that the coil is constructed from insulated materials, and that all electrical connections are tight and well-insulated. To make sure your design complies with safety requirements and standards, you should also think about speaking with a professional or seasoned do-it-yourselfer.

Installation of the heating system

The equipment required for the installation of an inverter heating system in the building must be determined before any work is done on it. The product’s power is selected considering heat loss and small stock, based on the area of heated rooms.

It is tentatively thought that 1 kW of heating equipment performance will suffice to guarantee typical microclimatic conditions within the 8–10 kV. m. area.

Features depending on the type of equipment

The type of power network required for the boiler’s connection is selected based on the boiler’s calculated power, which can be either one or three phases. The first is appropriate for devices up to 10–12 kW in capacity, which is typically utilized for gear heating or small homes. Inverters that have a capacity greater than 6 kW are intended to be operated in three phases.

Boilers between 6 and 12 kW in capacity can be linked to a network at a voltage between 220 and 380 volts simultaneously. It is permissible to use such equipment without adding a new circuit.

Additionally, they favor industrial equipment with larger dimensions, larger heat exchangers, and a complex current transformation system when selecting an inverter boiler for large-sized industrial premises. On the other hand, a reasonably small and inexpensive household model is required for use at home.

What to take into account when installing?

Boilers of the inverter type can be used in pressure and gravity heating systems. Installing a device in the system to dose water from the device to the overall pipe system is advised, given that the heat carrier heating rate is advised. As a result, the device becomes more effective and requires less heated fluid.

It is worthwhile to ascertain whether the current electrical wiring has sufficient parameters for the operation of new equipment before beginning installation. If needed, a sizable portion of the wires are swapped out for new ones. In case a three-phase network is required, extra cables are installed apart from the main power supply network. Furthermore, a specific protective unit that automatically cuts off the power supply when there are abrupt voltage drops in the network is needed for the equipment.

When setting up inverter heating, keep the following in mind:

  • provide for installation in the system of special air drilling valve;
  • about the installation of an expansion tank necessary to compensate for thermal expansion of the liquid, as well as the circulation pump (unless, of course, the system is non -pressure);
  • about the location of the boiler at a certain distance from items of furniture and other things;
  • Ground the equipment.

It’s also advised to fit the boiler with a remote control gadget like a GSM module or electronic programmer. With their assistance, you can offer fairly practical heating, such as in a country house that is only visited occasionally on the weekends.

Stam device

The heat exchanger, also known as the "Register" or "Snake" depending on the context, is the primary part of the combined heating system. The fuel contains a register that controls coolant circulation. The heating system is linked to this register.

As much as possible, the coil should heat the coolant without obstructing its even circulation.

Steel pipe or sheet steel are used in the production of heat exchangers. The latter is most commonly used because it is relatively simple to produce and handle. Additionally, cleaning it up after fuel combustion is quite simple.

The small heating area of steel heat exchangers is a drawback, though. Consequently, a register installed from a metal pipe will be the most efficient for large rooms.

How to assemble an induction heater with your own hands

The electromagnetic induction principle underlies the operation of a vortex induction heater. A magnetic field is created in the induction coil when a high-frequency electric alternating current flows through it. A heated liquid (water) is contained inside a ferromagnetic metal core, which is used as the coil’s core in the most basic scenario and is made of steel pipe. Foucault vortex currents heat a metal pipe that water flows through.

The end device in this instance was a closed system made up of two or three sections of steel pipes with thick walls that circulate water. A heating element, if you can call it that, provides isolation for the coil of copper wire, which has roughly 60 turns on a steel pipe with a diameter of 50 millimeters. First, a single-layer coil is wrapped around the pipe (in this example, FUM tape or fiberglass) to provide heat-resistant insulation.

Vortex induction heater is powered by inverter voltage converters

The source of electricity that a vortex heater will draw its power from piqued my curiosity the most. Numerous design options for "vortex heaters" were described online! It’s true that there wasn’t enough time to experiment with making toroidal and other kinds of heaters; instead, a description of a tiny, self-contained heating battery that was made at home was used as a model. The problem was fixed when an induction heater was installed in place of Ten!

"How to heat the water in the pipe?" was still the most crucial question. Several essential inverter voltage converter circuits were selected after "searching through the Internet." The decision was first made to stop using Kititutsky’s inverter, but the production of this device was put on hold because neither our creative association nor my "personal reserves" had any high-voltage "Mosfets."

The idea of creating a Kititutsky inverter, which has excellent technical qualities and a relatively simple scheme, will unavoidably be implemented in our creative association’s classes! (After manufacturing it, we believe to donate it to a car model laboratory, which is in dire need of a metal smelting apparatus to produce homemade auto parts!).

A powerful DC source of 12 V was used to power low-voltage field transistors in an inverter, which was created as a converter. In order to adjust the device, an acid car battery was used. Voltage 6 V was used for the device’s initial inclusions (not all batteries were used).

The TL494 chip’s setting generator was linked to a low-power, variable power supply that ranged from 0 to 15 V. Next, a computer power supply was utilized to supply its power. Initially, it was imperative to guarantee consistent generation of the generator’s output signal. The fact that the output transformer’s optimal coordination is not guaranteed when the inverter’s diet is reduced raises the question of why t.D., which was intended to withstand meals at 12 V, failed!

We just didn’t think about the output impulse form during the inverter’s initial testing! Achieving uniformity in the shape and amplitude at the TL494 and driver transistor outputs was crucial. Since neither I nor my students had much experience with power electronics, we were "careful not to do problems" with transformers and output transistors.

How to make a heat generator with your own hands

Vorthy heat generators are extremely intricate machines; however, in theory, one can construct an automatic VTG Potapova, whose design is appropriate for both domestic and commercial use.

Thus, the 93% efficient mechanical heat generator Potapova, whose schematic is depicted in the figure, emerged. Though Potapov’s device is especially effective with home masters, Nikolai Petrakov was the first to receive the first one.

The vortex controller’s design is depicted in this diagram. A flange connects the mixing pipe 1 to the pressure pump, which provides a liquid at 4 to 6 atmospheres of pressure. A vortex is created in drawing 2 when water enters the collector and is directed toward a unique vortex pipe (3), whose length is ten times greater than its diameter. The water whirlwind travels to the hot pipe via the spiral pipe at the walls. This end terminates bottom 4, which has a dedicated hole for the hot water release in the middle.

To control the flow, in front of the bottom there is a special braking device, or a rectifier of the water flow 5, it is a few rows of plates that are welded to the sleeve in the center. The sleeve is disposed of a tube 3. At the moment when the water moves along the pipe to the rectifier along the walls, a gas stitch current forms in the axial section. Here the water moves towards the fitting 6, which is cut into the wall of the snail and the fluid supply pipe. Here the manufacturer installed another disc rectifier of flow 7 to control the flow of cold water. If heat comes out of the liquid, then it directs it along a special bypass 8 to a hot end 9, where the water is mixed with the heated with the mixer 5.

The liquid enters the radiators straight from the hot water pipe and then makes a "circle" to return to the coolant for further heating. The liquid is then heated by the source, and the pump completes the cycle.

Such a theory even suggests modifications to a heat generator for low pressure serial production. Sadly, projects are only useful on paper; very few people actually use them. This is especially true when you consider that calculations based on the Virial Theorem are required to account for the sun’s inconsistent energy as well as centrifugal power in the pipe.

The following is the formula:

Where the sun’s kinetic movement is expressed as Ekin = mv2/2;

The planet’s mass (m, kg).

The following technical features of a vortex-style household heat generator for Potapov’s water are possible:

Operating principle

The origins of the rotational vortex effect in the total absence of motion and magnetic fields are explained in a number of ways.

Since the gas is moving quickly inside the device, it functions as a rotation body in this instance. This principle of work deviates from the widely recognized norm, which states that hot and cold air should be handled separately. According to the laws of physics, different pressures are formed when flows are combined, and in this case, this results in the movement of a vortex of gases.

You can use devices for both efficient cooling and heating because of centrifugal force, which causes the air temperature at the output to be significantly higher than it is at the input.

There is another theory of the principle of operation of the heat generator, due to the fact that both vortices rotate at the same angular velocity and direction, the inner vortex corner loses its corner moment. The reduction of the moment is transmitted to kinetic energy to the external vortex, as a result of which the detachment currents of hot and cold gas are formed. This principle of operation is a complete analogue of the Peltier effect, in which the device uses the electrical energy of pressure (voltage) to move heat to one side of the transition of heterogeneous metals, as a result of which the other side is cooled and the energy consumption is returned to the source.

Benefits of a vortex heat generator include:

  • Provides significant (up to 200 º C) temperature difference between the "cold" and "hot" gas, it even works at low input pressure;
  • It works with efficiency up to 92%, does not need forced cooling;
  • Converts the entire stream at the entrance to one cooling. Due to which the probability of overheating of heating systems is practically excluded
  • The energy produced in a vortex tube is used in a single stream, which contributes to the effective heating of natural gas with minimal heat losses;
  • Provides the effective separation of the vortex temperature of the inlet gas at atmospheric pressure and the output gas at negative pressure.

Depending on the modification, this alternative heating method can heat a room up to 100 square meters for practically no cost. The primary drawbacks are its high cost and infrequent practical application.

Inverter heating of the house, what and how it works

Inverter heating boilers stand out among the many other varieties of heating systems due to their numerous differences in a wide range of parameters. Inverter heating is one of the types of devices that heat a house using electricity.

Since the majority of electrical heating structures typically use a sizable amount of energy, manufacturers work hard to make these systems more efficient. The functioning principle and characteristics of inverter heating will be discussed in this article.

Advantages and disadvantages of inverter heating

The impressive list of differences is as follows:

There are no movable parts and mechanisms in the design of inverter boilers, therefore the wear resistance of such devices is higher. Thus, the service life of inverter boilers is much higher than similar devices of a different type and usually is at least 10 years. Inverter boilers have a fairly simple design, and if necessary, it can be assembled independently. The coolant in inverter boilers heats up much faster than in any other heating system. The reason is simple: there is no familiar heat exchanger in inverter devices, so all thermal energy is heating the coolant. Almost every inverter boiler can work with any type of coolant, since the working elements of the boiler with the coolant do not enter into direct contact. The coolant can only affect the characteristics and indicators of the heating system, but the boiler will operate in the standard mode. Inverter boilers are quite expensive: when compared with ordinary household appliances, then an inverter boiler will cost at least 2-3 times more. Household inverter boilers have a large weight, but the dimensions of such devices compensate for this drawback. In addition, a successful form allows you to arrange such a design almost anywhere. The boiler adjustment is carried out using complex electronic systems that will ensure continuous operation and control of the boiler parameters. Thus, despite the simplicity of the assembly of the boiler itself, for the independent creation of controlling elements, you will have to study electronics. The installation of electronic systems is mandatory, otherwise the equipment can get damage and fail. Inverter heating devices do not create noise and relate to fireproof devices: during operation, fuel is not used, due to which ignition can occur, and there are no movable elements. Such systems are environmentally friendly: since the fuel is not used, there are no emissions into the environment, because there are no combustion products.

Autonomous power sources

An excellent way to heat the house is with an inverter heater. Such a design is typically fairly expensive to acquire and install, but over time, the system’s good indicators more than offset these costs.

The induction boiler is used for

  • – heating of residential premises;
  • – heating of administrative and industrial buildings and structures;
  • – heating of structures with special prescriptions on safety and ecology;
  • -reservation of heat supply sources;
  • – use in the hot water supply system;
  • – correction of the heat supply process during the operation of an unstable renewed energy source and low -grade local fuel;
  • – connection to systems with combined (bivalent) heating;
  • -connection to the heating system with remote control;
  • – use in technological heating systems using intermediate liquid coolant (up to 115 ° C) both in flowing systems and with a chamber reactor.

Cavigating heater and its types

There are various types of calibration heaters. You must comprehend the types of generators in order to determine which one you need.

Cavitation heater types:

  1. Rotary
    – The most popular of them is the Griggs apparatus, working using a centrifugal rotation pump. Outwardly it looks like a disc with holes without exit. One such hole is called: Griggs cell. The parameters of these cells and their number depend on the type of generator and the speed of the drive. Water heating occurs between the stator and the rotor by means of its rapid movement on the surface of the disk.
  2. Static
    – He has no rotating elements, and the cavitation create special nozzles (laval elements). The pump pumps water pressure, which leads to its rapid movement and heating. The output holes are sopel more narrow than the previous ones and the liquid begins to move even faster. Due to the rapid expansion of water, cavitation is obtained, which ends with heat.

It’s true that the absence of rotating parts results in less wear on the static heater. The device has a five-year lifespan, and replacing the nozzle is a simple process that costs significantly less than replacing the heat generator in a rotary cavitator.

Working scheme of the induction heater

The following components are found in the heater of the inductor type.

  1. Current generator. Thanks to this module, the alternating current of the household power supply is converted into a high -frequency.
  2. Inductor. It is made of copper wire twisted in the form of a coil, for the formation of a magnetic field.
  3. A heating element. Is a metal pipe placed inside the inductor.

When the mentioned components interact with one another, they all function in accordance with the following principle. The inducer coil constructed of copper conductor is filled with the high-frequency current produced by the generator. An inducer transforms high frequency current into an electromagnetic field. Furthermore, the coil’s vortex flows cause heat to transfer to the metal pipe inside the inductor. Thermal energy is transferred to the heating system by the coolant, or water, as it passes through the heater. The coolant prolongs the heating boiler’s "life" by serving as a cooler for the heating element.

The induction heater’s electrical circuit is shown below.

The metal heater’s operation is depicted in the following picture.

Materials Needed Steps to Build
Copper tubing, plastic tubing, PVC pipe, copper wire, water pump, power source 1. Create a coil with copper tubing to act as the heating element. 2. Wrap the coil around a PVC pipe to form the boiler. 3. Connect the tubing to a water pump to circulate water through the coil. 4. Connect the coil to a power source to induce heat. 5. Insulate the boiler to retain heat efficiently.
