Electrode (ion) boilers are a type of electric boilers and are intended for use in autonomous heating systems. Main distinguishing feature this heating equipment– a block of electrodes that replaced a traditional heating element as a heating element.

This made it possible to eliminate some problems of units on heating elements - fragility heating elements, low efficiency, difficulty in controlling heating using modern species automation.

Operating principle of an electrode boiler

In heating equipment of this type Heating of water occurs due to ions moving between the electrodes. When the unit is turned on, the coolant ionizes, during which the molecules break up into ions: positive and negative. The resulting ions are directed to the electrodes: negative and positive. This process is carried out with the release of heat, which is transferred to the coolant. Thus, direct heating of the liquid occurs without the participation of “intermediaries”, which are heating elements.

The water that is in heating units plays the role of an element electrical circuit, requires special preparation to obtain the required electrical resistance value. Preparation usually involves adding table salt to the water.

The power gain in ionic units occurs gradually. When heating the coolant, it electrical resistance decreases, the current increases, the amount of heat increases.

It is possible to connect an electrode boiler in combination with other types of heating equipment: or. If necessary, a diagram can be used for an existing heating system parallel connection two or more electrode units.

The Galan boiler is a product of conversion developments

The heating unit "Galan" is produced according to the standards required for military equipment, since this device is a conversion development of enterprises that produce devices for heating submarines and warships.

The Galan electrode boiler is a cylinder with a diameter of 60 mm and a length of 310 mm. Current is supplied to the unit using concentric tubular electrodes, then transferred to the coolant. The heated coolant is distributed by a circulation flow through pipes and radiators. In heating systems with Galan electrode devices circulation pump serves to speed up the heating of the coolant, and then it can be turned off.

Advantages of the Galan brand ion boiler:

• presence of a built-in sensor for automatic heating control;
• high efficiency – up to 98%;
• low sensitivity to voltage changes;
• low power consumption;
• no need for approval for installation and use with boiler inspection;
• more compact dimensions than heating elements units;
• low cost - from 250-300 dollars.

A special antifreeze “Potok” was developed for these units. Additives to this liquid slow down the formation of scale on the walls of the device and the occurrence of metal corrosion processes.

When installing the electrical part of the heating circuit with your own hands, you must use the “Instructions” of Glavgosenergonadzor dated March 21, 1994, No. 42-6/8-ET.

"EOU" - energy-saving heating systems

"EOU" are electrode heating installations flow type. They can be used in closed water heating systems intended for heating dachas, cottages, industrial and warehouse premises with an area of ​​20-2400 m2. EOU are excellent.

Advantages of "EOU":

• economical, efficiency is approximately 98%
• compactness, single-phase modifications have a length of 300 mm and a diameter of 42 mm, three-phase models have a length of 400 mm and a diameter of 108 mm;
• can be installed in a closed water heating system of any type without installing a circulation pump;
• the use of special materials guarantees the longevity of the installation;
• the heating element will not fail if there is no coolant in the installation when power is supplied.

If not available, installation of electrode-type boilers is one of the most economical and reliable options organization of autonomous heating.

Rapid rise in energy prices, availability of new technologies on the market heating devices and the trend towards using environmentally friendly heating sources are fueling consumer interest in alternative options heating. Among them, we can highlight an ion heating boiler, which works with the most accessible energy carrier - electric current.

There has long been an opinion among property owners that heating using electric energy is a rather risky undertaking that can result in exorbitant operating costs. To be fair, it is worth noting that this opinion applies to electric boilers with an integrated heating element. The appearance of ion boilers on the market has made it possible to dispel the myth of high cost electric heating Houses. The unique design of the electrode heating boiler guarantees rational and economical consumption of resources.

Besides obvious advantage In terms of efficiency, the electrode heating boiler also has a number of other positive qualities, among them:

Operating principle of the device

Boilers with heating elements often suffered from breakdowns due to imperfect design and the use of short-lived heating elements. Criticism towards the design of heating element boilers is completely justified - these devices can overheat and create emergency situations on the circuit. Safe and efficient ion boilers with the highest possible efficiency are completely free of these disadvantages.

In ion-type boilers, a block of electrodes is used instead of a heating element.

Heating of the coolant occurs due to the action of ions that move between the electrodes. When the boiler is started, the coolant ionization process occurs, during which the molecules are divided into positive and negative ions. Next, the ions move to the electrodes with the corresponding charge. During the movement of ions, heat is released, which is transferred to the coolant.

Due to this, electrode heating boilers have the highest efficiency index. They provide reliable heating circuit with minimal heat loss. For example, the popular ION electric boiler allows you to save up to 30% of electricity compared to a traditional heating element heater.

Coolant for ion boilers

Installing an electrode boiler will not take much time from the owner. Compact anode heating boilers do not require connections to a gas exhaust system, do not require the construction of a special concrete pad and take up a minimum amount of usable space in the house. The only nuance that may puzzle the owner is the issue of compatibility of the electrode boiler with a specific coolant.

Ordinary water is not suitable for filling the system, so the owner will need time to purchase and prepare required composition. You can read more about liquid for heating boilers. It is worth choosing antifreeze in accordance with the recommendations provided by the device manufacturer.

Antifreeze must have the following properties:

As you can see, purchased ion heating boilers, reviews of which you should definitely read before deciding to install the device, will only work correctly with a certain type antifreeze. A properly selected coolant does not leave sediment and hard salt deposits on the internal components of the circuit and boiler, preserves the original properties of the heat exchange surfaces and contributes to the efficient and economical operation of the entire heating system.

Today there are three types of electric heating boilers on the market: induction, based on heating elements and electrode. Electrode boilers They are also called ionic or ion exchange, but these are the same devices.

Principle of operation

This equipment differs from other electric boilers in the presence of open electrodes, to which current is supplied from the network (alternating with a frequency of 50 Hz). The electrodes are placed in water of a certain chemical composition. When a potential difference occurs in the electrolyte, which is water, the ions begin to move. Due to the constant change of potentials on the electrodes, the movement of charged particles is chaotic. When ions move, it releases a large number of heat, which heats the coolant (water in this case).

Advantages and disadvantages

Is it convenient to use this type of boiler for heating? I guess, yes. It is especially good in places where the network voltage is unstable: even when the voltage drops to 180 V, the electrode boiler continues to operate. Its power drops, but it continues to work. What else is such a system convenient for: in the presence of competent automation and correct connection The boiler system is autonomous and can maintain the set temperature independently. Another positive point: if for some reason water disappears from the system, the equipment will simply stop working. It won’t burn, won’t deteriorate, but simply won’t work, since water, in this case, is the working medium. Without it, there is no current.

Now about the disadvantages. From the principle of operation of the electrode boiler, their main drawback emerges: they are demanding on the composition of the water. Not just any water is suitable, but with certain characteristics. When starting the system, it is necessary to prepare the coolant according to the recommendations of the boiler manufacturer. Usually this is a few teaspoons of salt or soda per liter of water in the system. That's all. You can also use special liquids that are produced by the same manufacturers. But this is for those who don’t want to bother at all.

On the other hand, by changing the composition of the water, you can “adjust” the boiler’s power to your needs: in principle, you can make it work with both more and less power relative to what is stated in the passport. All you need to do is change chemical composition coolant-electrolyte. Here it is important not to overdo it, otherwise you can “modify” the composition until the boiler completely and instantly fails. Therefore, stay within the limits specified by the manufacturer (as usual, “from” and “to” are indicated).

Another unpleasant moment. Even more. The current spreads in the water, and the water circulates in the system. And, in principle, it is not impossible to touch the radiator and receive a considerable electric shock. One more thing follows from this an indispensable condition safe work when using electrode boilers for water heating: high-quality and reliable separate grounding is required. It will just help avoid such a situation.

Not the most pleasant moment is the need to periodically clean the system and replace the electrodes - they gradually become thinner and the heating efficiency decreases. In this regard, electrode boilers do not have any advantages over traditional ones. electric boilers with heating elements.

How economical are electrode boilers?

There is constant debate about the energy consumption of electrode boilers. Sellers and manufacturers claim that these boilers are more economical than heating elements. They even name a figure – 30%. Their opponents say that if the boiler is 6 kW, then it will consume 6 kW. No more, no less.

This is true. But owners of operating systems claim that they pay less for heating (some previously had heating elements, and some compare their bills with the bills of friends). Note that negative messages are written only by theorists who advocate the use of good old, well-known heating elements. There is not a single negative review from the owners (5 forums viewed).

There is one conditionally negative: after 2.5 years of “excellent” operation, the efficiency of the system dropped significantly, and it was only possible to improve it partially, but not enough, by careful preparation coolant. At first glance, a significant reduction in the power of the heating unit is possible for two reasons: the electrodes are worn out and need to be changed, or something is wrong with the automation. In any case, you need to contact service center to specialists.

How can an electrode boiler for water heating at home benefit? Due to the low inertia of the system: there are no intermediate carriers, and all the energy is immediately transferred to the coolant. This is important not only during system startup, but also to maintain a given temperature regime. As soon as the air temperature in the room (for greater comfort you need to monitor this indicator, not the temperature of the coolant) becomes lower, the system turns on. Heating begins instantly, without delays for heating the same heating element.

The situation is the same with the shutdown: the power supply is turned off, the heating stops. And again, there is no inertia, and the temperature remains stable, and there is no excessive wastage of electricity. This is true. But in order for everything to be as described, high-quality automation is necessary, and this, as we know, is not cheap.

Practitioners say that electrode and induction boilers more suitable for the device than boilers using heating elements. They have more advanced automation and the temperature is maintained more accurately. But modern multi-stage boilers using heating elements can also regulate their power, although this transition is abrupt - turning on/off one or more heating elements gives a power jump. So if you choose, preference for organizing water heated floors can be given to electrodes. They are also good in this area, but they are much more expensive.

The advantages of using electrode boilers for water heating include their small size, low cost (even in relation to boilers using heating elements) and noiselessness during use (unlike induction boilers, which are sometimes very noisy). But here you need to take into account that in addition to the need for a separate power line, you will also need to build a separate grounding circuit, and this is also a cost.

In general, it is impossible to say unequivocally whether electrode boilers are good or bad. There are some positive aspects, but there are also sufficient quantity negative. Actually, you need to decide in each specific case: as always, when there are several options, the problem of choice arises. But everyone makes their own choice. We are trying to present the situation as fully as possible, but it’s still up to you to decide.

Galan electrode boilers: table of characteristics and reviews

Therefore, it is quite difficult to suspect them of bias, and they persistently promote electrode boilers. They produce flow-type equipment. This is good because the installation of such a unit does not require approval from the boiler inspection department. Another positive point: electrode boilers from this manufacturer can be used in conjunction with another hot water boiler.

Now about the characteristics and prices. The data was taken from the official website, prices there are displayed in rubles, but due to the instability of the situation, we converted them to dollars at the current rate. Therefore, some errors are possible.

	Power consumption/voltage	Room volume m 3 / m 2	Coolant volume	Price	Dimensions

Important! The table shows the price only for the boiler itself. You also need automation, which, depending on the functionality and capabilities, costs from $50 to $150; you will need sensors (each about $15) as well as a circulation pump.

Of the entire range, mini-electrode heating boilers “Galan Ochag 3” are probably more suitable for heating a dacha. They will also be good for studio apartment. Available in 2 kW and 3 kW capacities. Boilers with a lower power of 1 kW have not yet been found anywhere. Reviews about all Galan electrode boilers are positive. But almost all of them indicate: you need to follow the rules for installing and preparing the system: check the water and bring its composition to the required levels, or fill in a specialized solution produced by the same company. Properly selected automation plays an important role. There is an announcement on the manufacturer’s website: “We are not responsible for the operation of boilers with non-recommended automation.”

Galan produces both electrode and heating element boilers

The most reviews come from owners of Galan Geyser 9 boilers. There are no dissatisfied people. Here are some facts that relate to the issue of electricity consumption by these boilers:

• House 135 m2 in Kharkov region. Galan Geyser 15 is heated. During the heating season 2012-2013, the meter showed 2750 kW.
• Room 120m2 in Dnepropetrovsk region. Galan Ochag 5 installed. The owner says that he “missed the mark” a little - he needs Hearth 6.
• House 150 m2 in Energodar (which is not specified). The cost of “Galan Geyser 15” for the 2013-2014 season in frosts down to -25°C per month on the meter is up to 1300 kW.

The reviews do not indicate the materials from which the house is built, how it is insulated and many other nuances, but certain conclusions can be drawn. Almost every review indicates that you need to monitor what kind of fluid is poured into the system. In one of the messages, a person repairing heating systems responded to a call: the electrode boiler had stopped heating completely. All due to the fact that the system was filled with ordinary, unprepared tap water. After working for a couple of weeks, the boiler stopped heating. After flushing the system and cleaning the electrodes, the coolant temperature still did not rise above 35 o C. The owner bought new electrodes and fluid for these systems, and after installation and repeated flushing, everything works.

In general, it turns out like this: electrode boilers are simple in design, but demanding to operate. Coolant parameters and high-quality automation are important.

And electrode ones. The latter will be discussed in the article.

Electrode boiler

Characteristic

An electrode boiler (also called an ion or ion exchange boiler) differs from other units operating from the network in that it has an open electrode to which current is supplied.

Refers to direct heating heating devices in which heat is directed directly to the energy carrier. This makes it possible to instantly increase the power of the structure, because there are no obstacles in the heat transfer process.

Heating is carried out using electrodes, which are immersed in a tank of liquid. Current is conducted through the coolant with a frequency of 50 Hertz and creates a barrier to electrolysis. Therefore, the inside of the boiler remains free of scale deposits.

The heating process of the liquid occurs with the help of resistance that appears. This happens very quickly. Thus, the container (tank) may not be large in size, since it is not necessary to wait for the liquid to be heated by the element. Such design properties of this boiler allow you to save the user’s budget by reducing energy consumption in the heating system.

An electrode heating boiler is very sensitive to the composition of water; ordinary tap water cannot be used to operate the unit.

Before installation, special preparation of the liquid is required. It’s good if there are antifreezes available that are recommended by the manufacturer.

It also has another feature, which is the gradual dissolution of the electrodes. This is a natural process, its acceleration and deceleration depends only on the intensity of use of the heating system.

Advantages and disadvantages

To begin with, it is worth saying that it is advisable to install electrode boilers only in those places where there is reliable wiring and a stable network. If there are periodic power outages and strong voltage drops, then it is not worth installing electrode units, as they will not be able to work normally. However, in this case, a solution can be found. For example, buy source uninterruptible power supply or diesel generator.

It accumulates a small amount of energy, which should be enough for a couple of hours of boiler operation. emergency situation. There are UPS models that adjust the voltage using a built-in stabilizer.

Advantages of an electrode heating boiler:

1. Safety for human health is at high level. Ion heating boilers are designed in such a way that current leakage is practically impossible. Fire is excluded, so the structure can be used to maintain a minimum temperature without constant human supervision.
2. Small dimensions and the possibility of installation in a heating network operating on gas fuel. It turns out that the electrode boiler starts after the supply of gas fuel is stopped.
3. Fast heating of the coolant, quiet operation, easy replacement of heating elements without replacing the entire device.
4. If desired, it can be installed in residential premises without installing a chimney and the boiler room itself.
5. High efficiency, which reaches 96% during operation, and when heating, energy savings are 40%. Plus the absence of dirt, dust, smoke and soot.

On average, an electrode electric boiler consumes 40% less electricity than another heating device from the network. Users note this nuance as the most important advantage of the unit.

Like any heating system, an electrode electric boiler has its drawbacks.

The disadvantages of these units include the following points:

• Considerable cost of electricity. Electricity is much more expensive than, for example, gas, but at the same time it is perfect for providing heat to a house that is located far from settlement and is visited from time to time.
• Not universal. An ion boiler for heating a private home is often not compatible with certain types of pipes and batteries. As an example, we can cite the use of cast iron radiators in a heating system, when problems arise due to unevenness inside, as well as a large volume of liquid. Typically, one section of a cast iron battery is designed for 2.5 liters of water.
• Problems using . In this case, it is advisable to use.
• The requirement of an ion exchange electric boiler for constant coolant resistance. It can be adjusted by adding additives that prevent the appearance of scale.

Operating principle and device

Electrode boiler device

Electrode boilers for heating a private house operate according to the standard laws of physics. The liquid in the unit is heated not with the help of any element, but with the help of the molecular decomposition of water into differently charged ions. Two electrodes are mounted in a container with coolant, and the supply of electricity is started. Water molecules under the influence of a current with a frequency of 50 Hertz (the number of vibrations per minute) are divided into positively charged and negatively charged ions. At the moment of the separation process, heat is produced. Each ion is drawn with its charge to a specific electrode.

Heating of water is very fast, since the resistance of the coolant is high and the electrolysis process prevents the appearance of scale on the walls of the boiler. We can conclude that an electric electrode boiler is an ever-functioning device.

The design of such a boiler is not complicated. This is a unit of small dimensions in the form of a pipe, which constantly crashes into the pipe junction system by threaded connection with the help of the Americans. In addition, the electrodes are connected at one end of the device. The coolant fluid is launched through the side pipe, and the exit is through the unoccupied end.

How to make an electrode boiler with your own hands

The main skill you will need is the ability to operate a cooker. The main parts for the design are a metal tube and an electrode.

Let's get started. To make an electrode boiler with your own hands, you will need the following elements:

1. Welding machine.
2. Pipe with a diameter of up to 10 cm and a length of no more than 25 cm.
3. Electrode (you can take a small metal rod with a diameter of about 11 mm).
4. The appropriate size tee.
5. Coupling .
6. Insulator for electrode and terminals (grounding, neutral).

Let's start the assembly process:

1. At the first stage, you need to screw on the coupling with a tee on both sides and tighten the products firmly to prevent leaks.
2. At the second stage, you need to immerse the electrode from the tee side into the pipe, firmly installing it inside using a dielectric insulator. You can use a stub with bimetallic radiator The goal is to create space between the pipe and the electrode. You only need to make a hole in the plug required diameter, insert the rod there and secure it firmly with a nut from the outside.
3. The next step is to weld a pair of bolts on the pipe body (M8 or M10). They are necessary to connect the zero terminal and the ground terminal. Exposed connection points must also be protected to limit yourself from electric shock.
4. The fourth stage will be the installation of the boiler and its piping. The dimensions of the structure are not large, so it can be hidden under the sink.
5. All. You can run coolant for electrode heating boilers and test the heating system.

Review of ion boiler manufacturers

On Russian market There are several popular manufacturers of electrode energy-saving boilers. Increasingly, those who want to purchase warmth and comfort are buying electrode boilers Galan, EOU, Innovator, etc.

Let's take a closer look at some of the manufacturers.

Electrode boilers Galan. User reviews indicate the demand for this brand in the market of ion heating equipment. Galan is a Moscow company, but its products are supplied far beyond Russia. Her first patents date back to 1990.

The Galan range of electrode boilers is represented by various names and three lines. Also, they all differ in power characteristics.

You can highlight the first series, Galan "Vulcan", designed for heating large houses, apartments and public buildings. The series operates only from a three-phase network and is represented by models with a power of 25, 36, 50 kW.

Electrode boiler Galan Vulcan

Second series Galan "Geyser" is a line of average power characteristics. There are only two items in it, which have powers of 9 and 15 kW. These electrode boilers are well suited for many medium-sized private houses.

The third series is presented more compact models power from 2 to 6 kW. Line called "Hearth" has serious characteristics, despite its compact dimensions. Easily heats small houses.

Galan electrode boilers have undergone virtually no changes throughout their existence; they have a reliable and proven design. While the automation for the units is constantly changing and supplemented in accordance with the wishes of users.

Electrode boiler EOU. The abbreviation stands for “Energy Saving heating installation" This is a Russian company that has long established itself in other countries far and near abroad. Its products have international quality certificates.

Electrode boiler EOU

IN model range EOU two lines. The first of them is designed for single-phase network 220 V and is represented by powers from 2 to 12 kW, the second operates in the presence of a three-phase network of 380 V, and different brand names have individual powers of up to 120 kW. You can notice the same solution in the external representation of the units.

EOU company is responsible for uninterrupted operation products for 30 years and even provides a guarantee for the first ten years.

Electrode toroidal boiler Innovator. When mentioning this company, they talk about a toroidal electrode boiler. Reviews online indicate high efficiency(up to 99.9%), as well as about product quality.

The Innovator electrode boiler is a simple design, small size, stability and reliability, which are accompanied by broad requirements for liquid quality and the need for a constant supply of electricity. But there are quite a few disadvantages compared to the advantages of the models.

Electric toroidal boiler Innovator

The advantages of such a boiler are the ability to adjust the power of each model from 1 to 20 kW, easy installation in any heating system. The toroidal electrode boiler can operate in single-phase, two-phase and three-phase networks.

Dimensions 30*10*10 centimeters.

No steel pipe is required for installation. The Innovator toroidal electrode boiler operates silently and has a service life of 30 years.

The manufacturer guarantees for 60 months.

Cost - 8,200 rubles.

Initially, the ion boiler was developed for heating submarines. The expectation was that the device would be small and would work quickly and quietly. There were no problems with electricity on nuclear submarines, so the boiler should be electric. Like many other useful inventions, this unit migrated from the field of weapons to the civilian sphere and quickly became very popular.

Operating principle of ion heating boilers

An ion heating boiler heats water using electricity, but the operating principle is different from a heating element. In this process, the determining role is played by the ability of water to conduct current, or more precisely, the resistance of the liquid. Remember a boiler made of two blades connected by matches. In it, current from one blade to another is transmitted only through water, as a result of which it quickly boils. An ion boiler does the same thing, but instead of blades, it has magnesium electrodes.

When current ions pass through water, friction is created with the salts that are in the liquid. As a result of friction, the temperature rises sharply. The more intense the current, the faster the heating process occurs. In addition, the amount of salts matters, and ion heating boilers do not work with distilled water.

When water enters the boiler flask, electricity, causing it to heat up. The boiler itself is small, about 30 cm in length. Accordingly, the coolant is in it for some seconds, but even this time is enough. These devices can be called the fastest among all heating boilers.

Design of an ion (electrode) boiler

Ion boilers are very simple devices. Essentially, it is just a metal housing into which an electrode is inserted. There are no adjustments or moving elements in it, there’s not even anything to break. They are:

• single-phase;
• three-phase.

In single-phase boilers there is one electrode, and in three-phase boilers there are three. The electrode is always supplied with phase (plus). Zero (minus) can be applied either to the housing or to the second electrode (if it is provided in the design). Grounding is also required to be connected to the housing. You can’t do without it, otherwise you’ll get an electric shock. It is important that the phase and zero electrodes do not contact each other. The only bridge for electricity should be the coolant. Naturally, the case has two holes for liquid circulation.

Which coolant is suitable for an ion boiler

An ion electric boiler is very demanding on the quality of the coolant. Distilled water is not suitable for it. As a coolant, you need to use ordinary tap water that has undergone special preparation. The heater's data sheet indicates how much salt should be contained in the coolant.

To “set up” the coolant for ion heating boilers, according to reviews, you need to spend a lot of time. For example, if the water resistance is insufficient, then it needs to be salted. Regular table salt is suitable. You only need to sprinkle a little bit of it, literally on the tip of a teaspoon. Then the salted liquid is passed through the system and the resistance is measured. If it has reached the required level specified in the passport, then you can leave everything as is. If necessary, add more salt to the coolant or dilute it with distilled water.

Piping an ion boiler in a heating system

As we have already said, an ion boiler is simply a flask with an electrode and pipes for connecting to the circuit. This unit does not contain any equipment that could regulate its operation, so everything necessary must be installed separately. In addition, you need to install required elements heating systems, without which the operation of a sealed circuit is impossible. As a result, we need to install:

• thermostat;
• fuse block.

Naturally, one cannot do without shut-off valves (Ball Valves) and American ones, so that the boiler can be removed from the circuit for maintenance. All contour elements must be placed correctly. The safety group is installed on the supply, behind the boiler. All other equipment is installed on the return line. A circulation pump is installed in front of the boiler, then a sump tank. Do not let any debris get on the pump impeller to prevent it from breaking.

It is imperative to make good grounding. Don’t joke with this, because we are talking about 220 W, and in three-phase boilers all 380 W can kill.

The expansion tank is installed in front of the pump, where the pressure is stable. Do not forget that sealed tank needs to be adjusted, otherwise there will be pressure surges in the system. The thermostat sensor is installed on the return line, where it takes readings of the coolant temperature. You can also use thermostats that control the degree of air heating. This way, you can maintain the same temperature in the room regardless of the weather.

Power from the fuse box is supplied to the boiler electrode through the thermostat. The latter works like a switch. When the water reaches the set temperature, the circuit opens and the boiler stops heating the coolant. When the temperature drops, the thermostat closes the circuit and the boiler starts working.

Maintenance of ion boilers

There is nothing to break in an electrode boiler. Maintenance of ion boilers, according to reviews, comes down to monitoring the amount of salts in the coolant and cleaning the electrode from scale. During operation, scale accumulates on the electrode. It can be removed mechanically, for example, with a grinder with a special brush attachment or coarse sandpaper. It needs to be cleaned until it shines.

In addition, over time the electrode decreases in size, aggressive environment It's eating away at him. Therefore, sooner or later it will need to be replaced. The main thing is not to miss this moment, since the operation of the boiler and the safety of all equipment directly depends on this.
