Electric boiler for heating a private house

The choice of heating system is very important when it comes to maintaining a warm and comfortable home. Electric boilers are becoming more and more well-liked as a practical and effective solution for heating individual homes. Electric boilers heat water using electricity rather than gas or oil like traditional boilers do, giving your house a dependable and healthy source of heat.

The simplicity and ease of installation of electric boilers is one of their main benefits. In contrast to intricate systems that necessitate substantial pipework and ventilation, installing an electric boiler can frequently be done with little disturbance to your house. For homeowners who want to improve their heating system without having to deal with the hassle of extensive renovations, this makes them an appealing option.

The adaptability of electric boilers is an additional advantage. They are simple to incorporate with already-installed heating systems, like underfloor heating or radiators, so you can alter the heating configuration in your house to suit your tastes. Furthermore, you have more flexibility and control over the temperature in your house with electric boilers because they can be operated remotely.

The energy efficiency of electric boilers may be a worry for certain homeowners. In some places, it is true that electricity can be more expensive than gas or oil, but in recent years, the efficiency of electric boilers has significantly improved. With their ability to reduce energy waste and increase heat output, modern electric boilers can help you save money on your heating bills over time.

In general, private homes can be conveniently, effectively, and sustainably heated with electric boilers. For homeowners looking to upgrade their heating system, they are worth considering because of their improved energy efficiency, versatility, and ease of installation. We’ll go into more detail about electric boilers’ features, advantages, and things to think about when selecting one for your house in the sections that follow.

The basic device and the principle of operation of the electric boiler

It will be much easier for some readers to understand the device and the principle of operation of the electrode boiler if they remember the uncomplicated way of rapidly boiling water with the help of a simple device. In student dormitories, where the commandants strictly monitored the compliance of the prohibitions, such a device was hidden, probably in every room. This is a cable, at one end of which a plug is installed for connecting to the network. And on the other – two razor blades, fixed in one way or another, but it is necessarily so that there is a small lumen between them. Instead of blades, other metal records were used: in army barracks, for example, horseshoes for boots often went into business. The essence of this did not change.

The easiest way to understand how an electric boiler works is to watch a student boil water.

The water heated up very quickly after the "assembly" was lowered into the water and connected to the 220 volt network. It took me less than a minute to boil a glass, so I didn’t have to wait long. Electrode boilers, also known as ionic boilers, operate on the same principle.

Keep in mind that because these experiments are so dangerous, it is not advisable to repeat them. A short circuit raises the possibility of an electrical accident or a potentially hazardous fire. These days, boilers that are made in factories are often small in size.

What exactly is the issue that requires such rapid heating? It is important to remember a few physical laws in order to comprehend the principle.

Even regular water has electrolytic properties (unless it’s distilled, of course), meaning that everything dissolved in it takes on an ionic structure, or all the positively and negatively charged particles combined. The directed movement of ions will start if you lower two direct current electrodes into such an environment: positively charged (cations) will go to the anode, and negatively charged (anions) will go to a positive conductor (cathode). We refer to this procedure as electrolysis.

However, in this instance, a 50 Hz variable voltage is employed. This indicates that there is a 50 times per second change in the polarity of the electrodes submerged in water. In such circumstances, ions move in an undirected manner by nature; instead, they vibrate and change direction at the same frequency. The movement energy becomes a thermal because such fluctuations take place in a relatively dense water environment, which significantly resists movement. Boiling water is the result of extremely quick heating in the area between the electrodes.

The electrode boiler also works in the same way, only the generated thermal energy is already transmitted by the flow of the coolant at heat transfer points – radiators. In all the other types of electric boilers, these or those metal parts act as a “gear -up link”. It can be a tubular body of the heating element, the labyrinth of internal channels or the case itself – in induction type devices. In the forehead, the coolant warms up only due to direct heat transfer. But in the electrode diagram of such a “intermediary” there is not in principle – the liquid environment itself, which is currently located between the conductors immersed in it, heats up.

They claim that this is comparable to the reality that a person from the military industry was able to apply this technology to their life; in this way, the heating of water for surface ships and submarine compartments is guaranteed. The necessary characteristics of compactness, speed, efficiency, and fire safety all work in favor of this.

A small digression, so as not to return to the problems of terminology. Electric boilers are sometimes called ionic – why, probably, it is clear. However, sometimes manufacturers emphasize just such a wording, trying to draw a certain border between these two concepts. They motivate the fact that in their devices high -precision management is implemented at the level of the “quantity and quality of ions” participating in the process of heating. This can be perceived as an advertising move or is seriously referred to this-in any case, such control is assigned to any electronics unit and requires the use of the precisely verified composition of the electrolyte-plate. But the principle of operation of the heating scheme itself – this does not change at all. So it will not be a big mistake to use any of these two formulations.

However, the term "cathode" or "anode" boiler is entirely inaccurate, as this type of circuit is essentially useless in a constant voltage regime.

An electric boiler can make a huge difference in your home’s heating system. Because they don’t need a fuel storage unit or flue, electric boilers are more environmentally and spatially efficient than traditional boilers. They have fewer moving parts, which makes them simpler to install and maintain. Furthermore, electric boilers can provide constant warmth without requiring frequent maintenance because they can be more efficient and quiet. A dependable and affordable way to keep your house warm and comfortable all year long is with an electric boiler, regardless of your goals for cutting down on carbon emissions or just optimizing your heating system.

How is an electrode heating boiler?

The most basic heating device is determined by how easily the boiler’s operating principle can be understood. Even though there is a fair amount of variation in the models available today, nearly all of them share a similar layout and are comparable to one another.

Although there is a wide range of models and power characteristics, most electrode boilers share a common layout.

The only differences between the various manufacturers are in the subtleties of their external performance and the features of their managing equipment, which is typically not a boiler and must be purchased separately.

Electronic boilers can be configured to operate on a three-phase, 380 V, or 220 V AC network. This establishes a variance in their design.

The single-phase electrode boiler’s schematic device diagram.

To begin with, think about how a single-phase boiler operates.

This is a cylindrical metal case (pos. 1). The metal case walls function as one of the electrodes in this department, in addition to ensuring the heat carrier duct. In order to accomplish this, the case has a terminal for the "zero" wire (pos. 2). Although the figure appears simplified, this terminal is frequently hidden because it was taken out of the boiler’s switching block.

The cylinder portion of the case terminates at a nozzle for attaching to the heating circuit supply pipe (position 3); the coolant that has heated up in the boiler will enter the system from this point (illustrated by a pink arrow). An additional pipe that is positioned perpendicular to the main cylinder’s axis supplies the heat carrier (pos. 4 and the blue arrow, respectively).

A second electrode is located exactly in the center of the main working cylinder (pos. 5). Naturally, one should keep an eye on the required space between it and the walls because it is during this time that the coolant will heat up quickly. The switching unit and the terminal for attaching the phase wire are situated on this side, where the working cylinder is drowned out. (Point 6).

For the purpose of clarity, the figure depicts a homemade boiler’s "layout." Naturally, all of this appears more realistic in the factory assembly models.

In actuality, the only differences between the three-phase models are in the electrode design and the overall product’s increased dimensions.

The only real differences between three-phase models are their dimensions and the arrangement and number of electrodes.

The boiler housing still has a terminal connection that is meant to switch the grounding and zero wire. Additionally, there are three electrodes (depending on the number of phases) inside the working cylinder that are structurally positioned at equal distances from one another, or at the corners of an equilateral triangle, on a common dielectric block.

The boiler part replaces the electrodes, which can be changed out for new ones in case of failure.

Ion heating boiler electrodes: three-phase on the left, single-phase electrodes with varying lengths on the right

Naturally, trustworthy hydro- and electrical insulation is installed in the region where the switching unit drowns out the sound of the operating central cylinder. In factory models, a unique insulating polyamide composition covers the case to reduce the possibility of an electric trauma occurring to the apartment’s occupants.

Electrode boilers come in a wide range of sizes; they can be small heaters that only heat one or more heating radiators or large installations capable of heating an entire building. These boilers are frequently connected in parallel to form odd "batteries," which can operate simultaneously or selectively depending on the demand for a higher or lower heating power.

From tiny boilers to strong installations, which are frequently put together by stacking whole "batteries,"

As a matter of fact, the majority of boilers on the housing itself lack any additional devices or control. Every management and control function is divided into distinct modules with different levels of complexity.

Boiler with a set of switching wires and a remote control module

The simplest control equipment consists of a temperature sensor that is mounted on the supply pipe and regulates the coolant’s heating intensity. Two sensors are already present in the more precise systems: one at the boiler’s access and one at the entrance. The control panel sets the required heating level, and the automation will power the electrodes according to the current values while accounting for their hysteresis (defined range).

Certain manufacturers of this kind of equipment have "chips" that are much more complicated in terms of control and management. Their primary purpose is to keep things comfortable while using the least amount of energy possible.

We will deal with the advantages and disadvantages of an electric boiler

This is most likely the most crucial question to ask because, as the presentation has already shown, a lot of real and fantastical benefits and drawbacks are associated with this kind of equipment. It is therefore preferable to take your time and figure it out for each item.

What are claiming the merits of ionic boilers?

  • If we consider electric boilers equal to power, then by compact size and low mass, ionic boilers are out of competition.

This is an undeniable feature; in fact, the contract’s small size is determined by its simplicity. This is particularly stated in light of the fact that induction models are "famous for" their massiveness and sizable dimensions.

  • The electrode boiler does not require approval procedures when installing, it does not need a chimney and additional supply ventilation.

It is impossible to dispute that all electric boiler equipment has benefits, and electrode models are no different.

  • Electrode is attributed to literally “fabulous” indicators of the efficiency – supposedly their consumption of electricity is almost half as much as other electric boilers.

Generally speaking, all electric collars aim for 100% efficiency; all electric energy is converted to thermal energy and there are no mechanical transfers or friction nodes, nor are any combustion products removed. It’s another matter entirely that, for example, boilers operating on the resistive principle of heating are more inertial, meaning it takes them longer to reach the nominal regime and much longer to pass through the electrode during "acceleration." But there aren’t really any benefits in the long run. It is absurd to anticipate a "influx of energy from the outside" because energy cannot be tricked by the fundamental law of physics.

  • Electric boilers are safe from the point of view that in the event of a coolant flow from the heating system, they will not lead to overheating and burning.

This is a very clear characteristic of them. The working cylinder’s chain is essentially open in the absence of water (coolant), and the boiler is theoretically unable to operate in such circumstances.

  • Ionic boilers are insensitive to network voltage drops.

This is highly debatable, if not awkward to say outright. Examine any heater that is resistant to voltage drops; it will likewise not be phased out; it will just experience a reduction in heating power. It and the electrode boiler are similar when viewed from this angle. Furthermore, a steady voltage is generally needed for the control and control unit, as well as any additional heating system equipment, rather than the heater itself. Thus, it remains challenging to install a stabilizer in situations where the local power supply is unstable.

Stable voltage is necessary for precise electronic control of heating boilers! Read a separate portal publication to find out more about how the boiler’s voltage stabilizer works and how to choose the best option among those that are for sale.

  • Heating of water in an electrode boiler is so rapid that the necessary pressure is created in itself, which allows you to do with natural circulation, without the use of pumps.

This is undoubtedly a serious misperception. When the system reaches the calculated mode, the difference in coolant density at the boiler’s entrance and exit will not be different from systems using other models of heating devices. In fact, this effect can be somewhat expressed immediately after launch.

The pump in the system becomes a necessary component when it is equipped with an electric boiler, as this addition increases its controllability and economy. Additionally, energy losses that are wasted trying to keep the coolant flowing through the system’s pipes naturally are not comparable to the cost of power supplies. Therefore, there are no preferences created in this regard by the electrode pump.

  • The compactness of electrode boilers allows them to install them in existing heating systems as additional sources of thermal energy.

With an electrode boiler that runs on solid fuel, you can always select the heating system’s best mode of operation.

Indeed, this is a common practice, and the electrode boiler can be installed directly at the radiators in residential buildings as well as in the boiler room, contingent upon the model’s power and dimensions. When the primary heat source needs maintenance or repairs, or just a break from technology, the secondary electrical device can be turned on "to help" the primary one or come "for replacement." It is thought to be particularly effective to use electric boilers in combination with other boilers that are connected to buffer capacities overall. This enables you to accumulate energy potential during the night of a preferred tariff.

Buffer container (heat accumulator): maximizing the home’s heating system Enhancing the heating system’s operating efficiency can be achieved directly through the accumulation of heat generated by a solid fuel boiler when burning wood or electricity while a preferential tariff is in effect. A separate portal publication covers how to set up a buffer container (heat accumulator) and how to properly choose such equipment.

The general coolant must match the electrode heating principle if a mixed diagram utilizing an electrode and another boiler is being used. Alternatively, a buffer container with an extra heat exchanger may be utilized to prevent coolant mixing.

  • The small inertia of the electrode boiler greatly simplifies the process of accurate adjustment of the heating system.

A highly debatable claim that, even with basic management systems, will only result in more frequent launch and stop cycles, which is definitely not a good thing. Furthermore, rather than changing linearly, electrolytes often undergo a change in electrical properties when heated. This means that accurate maintenance and proper debugging of the heating system are difficult tasks. In this sense, it appears that electric boilers with hets or induction are better.

  • The operation of electrode boilers does not harm the environment.

There are no emissions into the atmosphere, which is a feature shared by all electrical installations. However, electrode boilers are even less "prosperous"; the reason for their "brothers" weeks is the coolant’s chemical makeup, which frequently contains extremely toxic substances. According to all regulations, the disposal of such liquids must be handled by professionals and is never permitted to drain into the ground or the sewage system.

  • Electric boilers are famous for low cost.

Once more, it would appear that this is definitely the case because the heater itself is quite reasonably priced. However, a "marketing trap" appears quite frequently. The total cost will be very similar to, say, the heating room, in which all these nodes are already provided for. Add to the cost of the boiler the cost of the control unit, thermal attires, and the circulation pump.

Information regarding the efficiency of an electric boiler in heating a private residence might be of interest to you.

Furthermore, using an electric boiler without additional monitoring and control devices is not only highly risky but also unprofitable. It is equivalent to laying a bomb of a substitute action since an excessively fast heating of the water will eventually break.

Therefore, when making a purchase, you should consider the cost of all the components required for the efficient and secure operation of the electrode boilers in addition to their widely advertised low cost.

Actual and far -fetched disadvantages of electrode boilers

A cursory examination of the drawbacks associated with electrode boilers can lead to preconceived notions against this type of heating system. But is all of it true? Here, let’s investigate this a little more.

  • The coolant should always be of high quality, with a correctly selected, balanced chemical composition.

This is true, and there can be a lot of trouble at times. Good ionization, a sufficient heat capacity, a broad operating temperature range, safety from all angles, and no active chemical corrosion of the system’s metal components are all desirable qualities in a composition. If the resistance of the liquid is too high, the current might not flow through. Simply put, there are a lot of criteria.

Manufacturers of electrode boilers frequently have a list of coolants that are specifically approved for use with their equipment.

Certain coolant types are advised by many manufacturers of ton boilers, and failure to follow these recommendations may result in the equipment’s warranty being terminated.

Selecting the ideal composition can be extremely challenging for a novice owner, and choosing a composition "by eye" can significantly reduce the system’s effectiveness while theoretically maintaining operation, negating all of the primary benefits of ionic boilers. Considering that coolant "ages" quickly and changes in quality, necessitating frequent replacement, there are a lot of concerns about how convenient it would be to operate such a system overall.

  • The use of ionic boilers limits the owners with the choice of heating radiators

Completely justified criticism. Radiators made of steel or iron should not be used with these kinds of heating systems. Potential ferrous metal corrosion phenomena have the potential to alter the coolant’s chemical composition and lessen its electrolytic properties. Furthermore, the electrode boiler will operate virtually nonstop due to the exceptionally high heat capacity of cast iron and the large internal volume of these batteries; efficiency will be unaffected.

The selection of heating radiators by owners may be restricted by ionic boilers. High-grade aluminum or bimetallic materials are the best choices.

For these kinds of boilers, bimetallic batteries are the best choice. High -quality aluminum. However, cheap radiators made of secondary aluminum (typically by extrusion technology) are not advised because the metal will be heavily contaminated, which will quickly upset the coolant’s chemical equilibrium.

  • Another drawback from the same row – such boilers should not be used in the open -type heating system.

Everything is in order: atmospheric air free access to the coolant serves to both impress the required chemical composition of the liquid and sharply increase its corrosion aggressiveness.

  • Water from the heating system should not be used for domestic or technical needs.

Why this is exclusively linked to electrode boilers is unclear. A good owner would never have thought to remove water from the heating circuit—no matter what kind of boiler was placed there! There are alternative methods for doing this, like installing an indirect heating boiler, to provide hot water. Additionally, the electrode boiler is similar to others in this regard.

  • The circuit using an electrical boiler always puts forward special requirements for reliable grounding.

It is, indeed. From those vantage points, it is crucial to understand that, in contrast to all other forms of equipment, the electrode boiler’s body is an electrode in and of itself. If installing an RCD is the only option for other devices, then this measure will be ineffective as well because of the inherent characteristics of the operating principle, which state that leaks will inevitably occur and cause the RCD to operate continuously. Thus, only trustworthy grounding will guarantee security.

Electrode boiler operation does not permit any "liberties" with grounding; everything must be set up in accordance with the regulations.

In all fairness, though, we should point out that strong grounding is generally required for any powerful electrical equipment. Therefore, the issue isn’t so much a lack of ionic boilers as it is a matter of the increased standards for guaranteeing their operational safety.

  • The upper boundary of the heating of the coolant in systems with electrode boilers is 75 degrees.

Every boiler has a heating threshold, which can be monitored using control and control blocks. This threshold in electrode boilers results from the fact that, at higher heating values, the coolant’s electrolytic properties start to change significantly. This causes an unneeded electrical retaliation without producing any beneficial thermal return.

Nonetheless, for autonomous home heating systems, this kind of temperature threshold is typically sufficient to heat the space efficiently.

  • Electrodes of ionic boilers have a non -compliance service life, quickly overgrow, require replacement.

Very controversial. Maybe owners who used inferior coolant, which accelerated the formation of scale, came to this conclusion. In normal circumstances, electrodes are very useful.

However, even if the time comes to replace the malfunctioning parts (which happens with any electrical equipment at all), this kind of operation cannot be characterized as especially expensive or complicated.

  • Installation of an electric boiler, debugging and launching a heating system are quite complex procedures that require the involvement of specialists.

It would be necessary to divide the concepts in this case. On the other hand, installing the boiler in the heating circuit is a fairly easy process that makes sense. But unfortunately, you have to accept this when it comes to debugging. It is very difficult to accurately assess the coolant’s chemical composition and the system’s overall functioning efficiency if you lack the required equipment or experience. Thus, before the heating season begins, you should be ready for the yearly call for specialists to perform preventive work.

We sincerely hope that the data in this section of the publication will assist in carefully assessing the likelihood of installing this kind of boiler. If prospective hosts feel that this heating principle’s benefits exceed its current drawbacks, you can move on to selecting from the selection that is being offered for sale. About this, see the publication’s following section.
