Insulation and heating are essential components of maintaining a warm and comfortable home. Energy bills and comfort can be greatly reduced with efficient heating systems and adequate insulation, whether one is battling the winter cold or trying to keep a comfortable temperature all year round. The electrode boiler is one creative solution that’s becoming more and more well-liked among do-it-yourselfers.

An interesting substitute for conventional heating techniques is provided by electrode boilers. They don’t need fossil fuels like gas or oil because they produce heat using electricity. This offers more control over energy use while also lessening the impact on the environment. Building your own electrode boiler is not only possible but can also be a satisfying project if you have the right advice and a little do-it-yourself attitude.

The customization that comes with building your own electrode boiler is one of its benefits. You can customize the design to fit your unique requirements and available space if you make it yourself. Optimizing performance and efficiency is ensured by the ability to modify dimensions and features, regardless of the size of the home or apartment being heated.

However, where do you even begin? An indispensable tool for the do-it-yourself enthusiast is a drawing. They offer a visual manual that explains the different parts of the boiler system and where they are located. You can confidently start the construction process knowing exactly how each part fits together if you have access to clear and precise drawings.

This post will go into the world of electrode boilers, discussing their advantages, the parts that must be installed, and—most importantly—offering comprehensive blueprints to help you along the way. With the right advice and materials, building an electrode boiler is a doable project for anyone, experienced do-it-yourselfer or novice starting out on a new project.

Features of the design

The components of the most basic cathode boiler are as follows:

1. Body made of pipe. which can have a different diameter. This characteristic is often 50-200 mm .
2. Two fittings or 1 fitting and a plug. They are fixed on threads cut on both ends of the pipe.
3. Electrode. It is fixed in one of the liners. Of course, it is fixed on a material that is not able to conduct electric current. This electrode is inside the pipe. One end of it is connected to the contact, which goes outside through the lug.
4. Two sockets. Through one the water enters the heating network, through the other it returns from the system, which can also include an induction-type boiler.
5. Zero contact. attached to the casing.
6. Grounding contact .

The mains are linked to the electrode boiler in the following manner:

1. A phase wire is connected to the electrode contact.
2. Neutral and grounding cables are connected to two contacts placed on the pipe.

Principle of operation

Ion boilers function as follows:

1. Water with a certain concentration of salts is fed into the boiler.
2. The electric current travels to the electrode.
3. A positive charge is generated on the electrode and a negative charge on the body. Therefore, ions, which are charged salt particles, start moving towards the body. Since the frequency of current in the power grid is 50 Hz, the direction of motion of these particles changes 50 times per second.
4. The presence of charged particles of salt in water causes its resistance to electric current to decrease and the current to increase. The last current characteristic grows so much that water does not have time to conduct current through itself and starts to heat up. The level of heating depends on how high the concentration of salts in the water is and what the current strength is.

Pros and cons

Electrode boilers offer the following benefits, as the above illustrates:

1. Simple construction scheme.
2. Small dimensions.
3. Easy installation.
4. Fire safety.
5. Noiselessness of operation.
6. Small cost of components.
7. Low consumption of materials for self-manufacturing.
8. The possibility of connecting to single- and three-phase power grid.

Regarding the drawbacks, ionic boilers are unhappy about the following aspects:

1. To turn on the device, it is necessary to apply large electric current. For this purpose, a magnetic starter or similar devices should be used.
2. Need Use a coolant with the correct salt concentration. If it is too small, the current strength will be insufficient and heating will be weak.
3. If you create an electric heating boiler with your own hands, you need to spend a lot of time to determine the correct concentration of salts.
4. Except for water It will not be possible to use other heat carriers. Moreover, the water itself must be in proper condition. So, it is desirable to use a technical liquid without the presence of any metal impurities, which are rich in tap water.
5. Large consumption of electrical energy .

In order to create an electrode boiler by hand, you must first gather the following materials:

1. Seamless iron pipe. Diameter 57 mm. Length 30 cm.
2. Heat-resistant paint .
3. Primer.
4. Pipe with a diameter of 32 mm.
5. Metal plugs or lugs. 2 pcs. Their alternative is a metal sheet. True, it will have to be welded, not screwed on like plugs.
6. Electrode. Diameter 25 mm.
7. Terminals that have M6 threads. 2 pcs.
8. Paronite or rubber gaskets. 2 pcs.
9. Fluoroplastic bushing or glass-textolite.

It goes without saying that the materials should be taken in reserve because making a mistake significantly increases their consumption.

Manufacturing

Boilers with electrode heating are constructed in the following order:

1. Draw a scheme or drawing of an electric boiler. It can be made in two ways. The first variant of the scheme provides for completely plugged ends of the pipe-casing and placed near them side spigots for water supply to the heating network and return of the coolant from the heating radiators. The second variant of the scheme provides for the placement of one spigot on the opposite end of the housing from the electrode. Another branch pipe is placed near the main element of the electrode-type boiler.
2. Cut two short pieces from the pipe for the spigots.
3. On one of the ends of each spigot make two selections with a spherical shape. To do this, you need to take a bolgar with your own hands and cut out selections.
4. In a pipe with a diameter of 57 mm Cut two holes for the spigots. They should be located not only near opposite ends of the pipe, but also so that they are at the ends of the same diameter.
5. Thread is cut on the spigots and pipe. On the former it should be external. It is made on the raw ends. On the body The thread must be internal, it is made on both ends of the pipe. For thread cutting, you need to have the necessary tools and taps. If they are not available, you can contact a familiar turner or a turning company.
6. Grinding or finding plugs with the required diameter. The same is done with a fluoroplastic sleeve.
7. Weld the spigots to the body.
8. Weld terminals for connecting the neutral and ground wires .
9. Fix the fluoroplastic sleeve and electrode in the lug.
10. Put gaskets on the plug and the lug and screw the elements into the pipe.
11. Clean the product from dust and rust, degrease, primer and apply a layer of heat-resistant paint with their own hands. The latter must withstand a temperature equal to 120 ° C.
12. Check the electrode boilers made with their own hands for tightness. To do this, pour water inside, lubricate the seams with soapy foam, connect a compressor and raise the pressure to 3 bar. If there are no bubbles coming from the welding seam, all the work is done well. If bubbles appear, it is necessary to weld the holes. The homemade induction boiler with low electricity consumption is tested in the same way.

Of course, a thermoregulator and a temperature sensor (mounted on the water supply pipe) should be part of the electric boiler’s design. All boiler types, including three-phase induction-type devices, have these standard components.

Setting up the boiler

It entails choosing the appropriate salt concentration. We’ll use regular soda as the salts.

The following is the sequence of events:

1. Connect with their own hands ammeter to the power supply wires.
2. Connect the device connected to the heating system to the power supply.
3. Add a solution of soda to the system. The share of soda in the solution should be 10%. This solution is poured into the open expansion tank.
4. Waiting for some time. After looking at the ammeter. For a boiler made according to the above procedure, the current strength should be 18 A. Such a characteristic of the boiler, such as capacity, is equal to 4 kWh. The number on the device will be less than 18.
5. Pour the solution into the heating system. The flow rate should be small.
6. Waiting and looking at the ammeter again. If it showed 16-17 A, then refilling should be stopped. If this current characteristic is less, then the procedure is repeated. It is performed until the device shows 16-17 A. After that, the refilling is stopped, because otherwise the concentration will be too high and the electrode boiler will boil the water. Because of this, the pressure will increase, and in the best case there will be a release of steam. In the worst case, plastic pipes can burst if they were used to build the heating network.

How to make an electrode boiler with your own hands

Numerous manufacturers produce heating units that transmute electrical energy into thermal energy in various ways. However, if you know how to make an electrode boiler by hand, you can save a lot of money on the purchase. The device can be manufactured independently for a small to medium-sized country house because its design isn’t particularly complex.

Device and principle of operation

DIY electrode boiler

A homemade boiling pot with two blades screwed to matches is a familiar object. The electrolysis process forms the basis of the electrode boiler’s same mode of operation. Because it contains salts of various metals, ordinary water is a conductor. The charged salt particles, called ions, will constantly migrate from one contact to another and deposit on the metal contacts submerged in water if a direct current is supplied to them. The ions in our network will change their direction of motion 50 times per second due to the alternating 50 Hz current.

The fluid’s resistance decreases and particle movement becomes more intense when the amount of water passing through the electrode boiler is higher in salt content. Ohm’s law states that an increase in current strength results from a decrease in resistance at constant voltage. Since water does not conduct electricity as well as metals like copper or aluminum, it heats intensely when the current intensity increases. Electrode heating boilers accomplish this by turning nearly all electricity into heat. The concentration of salts in the coolant determines the strength of the current and then the heater’s power:

• P – power value, W;
• U – voltage in the network, for single-phase network is equal to 220 V, for three-phase – 380 V;
• I – current force, A.

The electrode heating boiler that is typically used by manufacturers has a cylindrical body composed of a piece of pipe with a round electrode inside. It functions as the initial point of contact for the phase wire. The body itself serves as the second contact, and the neutral wire is attached to it. The appliance has a third contact because it needs to have its body grounded in order to prevent electric shock. The artisans use the same blueprint to create electrode boilers by hand.

The order of works on manufacturing of the heater

The homemade electrode boiler drawing must first be studied; it shows a design that calls for the least amount of welding.

1. A heat-resistant paint coating; 2. A seamless iron pipe measuring Ø57 mm with an internal thread;3. Coolant inlet and outlet sockets measuring Ø32 mm with an external thread; Four metal plugs on the side; five Ø25 mm internal electrodes for the boiler; six M6 threaded connection terminals for grounding and connecting the neutral wire; and eight rubber or paronite gaskets.

If you have welding skills and the appropriate equipment, you can change the design by welding circles of metal instead of threaded plugs. Some masters make an electrode water heater with the coolant outlet upwards, installing a spigot instead of a plug. The inner electrode will need to be insulated from the body, for this purpose, you can use different fluoroplastic sleeves or make the plug itself from fiberglass plate. That and good electrode heating boilers, made with their own hands, that there is a wide scope for improvements and modernization using improvised materials. Only do not get carried away and make the device from different metals, they can form a galvanic pair, as a result, on one of the electrodes will actively grow scale.

Assembly instructions

Once you have a basic understanding of how to construct an electrode boiler by hand, you can move on to part preparation and assembly by following these instructions:

• Mark and cut pipes for the housing and spigots, make spherical-shaped cuts in them with the help of a bolgar to fit the cylindrical surface of the housing. Drill holes in it in the places of welding of spigots.
• All threads can be cut using special taps and dies for pipe threads. If there are no such devices, it is necessary to turn to a lathe shop. You can also grind the plugs, fluoroplastic sleeve and inner electrode there.
• Weld the prefabricated sockets and terminals for connecting the wires to the housing.
• Fix the electrode in the plug and install it in the homemade electrode boiler. Screw and tighten both plugs.
• The finished product can be painted with enamel resistant to temperatures up to 120 ºC.

It is essential to check the permeability of the welds after assembly. It is insufficient to just fill the device with water because the system has an operating pressure of up to 2 bar and an emergency pressure of up to 3 bar. Slag should be removed from the seams and soap foam should be applied. After using a compressor to generate excess pressure inside the housing, bubbles will start to form where there are no welds. The homemade electrode heating boiler can be installed in the furnace room and linked to the system using the following plan once the check is finished:

1) Electric heating installation; 2) Safety group, comprising air thrower, manometer, and safety valve; 3) Ball valve; 4) Heating appliances; Five: expansion tank; Six: emptying tap; Seven: strainer; Eight: pump.

Putting the heater into operation mode

The final steps include filling the system with water, adjusting the electrode boiler, and connecting the power supply and grounding wires. It will require modifying the coolant’s composition to get it up to operating capacity. Typically, tap water is utilized; however, it contains several harmful inclusions that cause scale to form on the electrode surfaces. If distilled water cannot be obtained, then tap or rainwater should be used to initially fill the system.

To set up, you’ll need the following tools and supplies:

• Current clamp or ammeter;
• soda;
• syringe;
• stirring tank.

Since the manually constructed electrode boilers in the above drawing will have a power of about 4 kW, the computation indicates that the circuit’s current should be 4000 W / 220 V = 18 A. To heat the water in the system, the device is plugged into the mains after the ammeter is connected to the power supply wires. At this point, a soda solution is created in a container with an approximate ratio of 1/10. It is preferable to add it to the system using a syringe at an open expansion tank or another location.

The ammeter’s initial reading after turning on will be less than 18 A. For electrode boilers, a soda solution is added to the coolant sporadically and slowly. The system needs to be completely heated at the same time. You must be patient because the process will take a long time if distilled water is added. When the meter reads 16–17 A, stop adding more; otherwise, the concentration might be exceeded. This poses a risk of steam ejecting and boiling or plastic pipes rupturing.

Conclusion

The electrode boiler takes up little room in the furnace room and is easy to make and operate. The specifications for the coolant’s composition are its sole weakness. If these cannot be completed, it is preferable to install an induction boiler, which uses eddy currents to heat the coolant without relying on the amount of salt in the water.

How to make an electrode boiler with your own hands

An apparatus that uses a heat transfer medium to heat water is called an electrode heating boiler. Rapid heating is encouraged by Brownian motion of ions, and the efficiency depends on the properties of the heat carrier.

Heat energy is solely derived from ionic motion. Moreover, it is transferred to the heat carrier. Up to 40% less energy can be used with the energy-saving electrode boiler. It differs from other boilers of this type in this way.

The principle of operation of the electrode boiler

Water is the system’s conductor, thus it needs to be prepared properly. There has to be a brine solution in the liquid. After dissolving in the water, the salt particles are added to the system. To avoid making a proportional error, it is essential to review the boiler passport.

Actions in the present flow through the water. Under these circumstances, avoid connecting the boiler via the RCD. If not, it will lower the system’s level of safety. The electrolysis that is created when the current flows through the water helps to produce the electrolysis gas. Such gas poses a serious threat to the system’s ability to function. As a result, it’s important to remember to deflate the air after every session.

Short-circuiting is not a concern if there is a heat carrier leak from the system. Power surges happen when the electrode boiler first starts up. An independent power source makes sense in these circumstances (see also "Electric fireplace with their own hands: just about complicated").

As the heating medium heats up, the conductor’s electrical resistance drops.A thorough examination of the electrode heating boiler is conducted. Furthermore, it is necessary to check the salt level (see also "How to make an electric heating boiler with your own hands").

Electrode heating boilers: pros and cons

Negative aspects consist of:

• The need to use gigantic capacities of electricity for connection;
• high electricity costs;
• Practical lack of safety;
• sharp spikes in electrical supply.

All of these drawbacks, however, are preventable at the same time. Boilers that use electrode heating will then have positive sides.

The following points can be attributed to the positive traits:

• innovative ways of controlling the system (e.g. via the Internet);

Electrode boiler with your own hands: steps

Following a specific order of steps is essential when building a boiler:

1. Working out the options of the heating system scheme – it is necessary to determine which principle of operation will be used. It is possible to stop on a single-circuit scheme for heating. Another option for a homemade electric boiler is to choose a two-circuit model. In the second case, heating and hot water are supplied simultaneously.
2. Arranging the grounding system.
3. Heating the liquid and starting its circulation throughout the circuit.
4. Use of radiators resistant to moisture.

Process of technological operations

Attach the "cup" to the pipe’s end by welding it there with a welding machine. On the back, an electrode is positioned and lowered to the "cup’s" bottom. The pipe’s two sides are then welded together. To install the electrode, fill the container with 0.7 liters of water. See also: "Heating with a hydro boiler."

Installing the pipe is done at an angle to the wall. Once the grounding process is complete, you can supply the phase to the electrode (use pipe "0" for this). After that, the 220 volt voltage must be turned on. A pressure gauge is used to regulate the power of the boiler. It has a three-way tap connecting it to the scheme in turn.

The electrode boiler, which is a home-made design, can heat up to 120 degrees Celsius. A closed-loop system keeps corrosion from developing. The boiler’s operational life is extended as a result.
