KVE boiler

An effective heating system is crucial for keeping your house warm and comfortable during the winter. A KVE boiler is one common choice for heating homes. However, what is a KVE boiler and how does it operate exactly?

Condensing vacuum hot water boilers, or KVE boilers for short, are an extremely effective and green boiler type. In contrast to conventional boilers, which heat water by burning fuel, KVE boilers heat water through a vacuum design. When compared to traditional boilers, KVE boilers are more efficient thanks to their creative design.

The condensing technology of a KVE boiler is one of its important characteristics. Heat that would normally be lost in conventional boilers can now be extracted from the flue gases by the boiler thanks to this technology. KVE boilers recover this heat to reach up to 98% efficiency, which makes them a great option for homeowners trying to cut back on their energy costs and carbon footprint.

Apart from their exceptional efficiency, KVE boilers are renowned for their small size and silent operation. They are therefore perfect for homes with small spaces or where noise is an issue. A KVE boiler could be the ideal solution to keep your house warm and cozy all year round, whether you’re building a new house or updating your current heating system.

Design features

Heating elements consist of two electrodes composed of a unique alloy that can withstand high temperatures. The coolant’s primary function is typically performed by water. One kilowatt of electricity is sufficient to maintain a comfortable temperature in a 65 m³ room while accounting for allowable standard heat losses.

The primary installation units are:

  • Boiler equipped with automation;
  • pump for circulation of the coolant (depending on the modification);
  • expansion tank to collect excess liquid;
  • pressure gauge, outlet valve;
  • mud filter;
  • automatic circuit breaker for current from 1A and electromagnetic starter.


Capacity is the primary indicator of electric boilers used for water heating. In this dependence, a higher 380V (three-phase scheme) or a 220V (single-phase scheme) source can be connected.


With the exception of the double-circuit boiler’s parallel circuit, which heats running water for domestic use, single- and double-circuit electric heating boilers are identically constructed.

The following components make up the electric heating boiler’s heating circuit, which is in charge of providing heat:

  • storage tank with heat exchanger;
  • heating element;
  • safety valves;
  • automatics.

This could include extras like that which the electric boiler’s manufacturer includes. It could be a circulation pump, control controller, or expansion tank.

The electric boiler’s hot water supply circuit is made up of the following components:

  • flow type heat exchanger;
  • heating element;
  • temperature sensor;
  • thermorelay;
  • automatics.

Certain manufacturers create products that simultaneously operate the heat exchanger on two circuits, heating the boiler in an energy-efficient manner.

Savings from the use of EHUs

Energy-efficient heating systems are silent, compliant with all fire and environmental regulations, and emit no chemicals that are dangerous to people’s health.

By using EEU, you can optimize your electrical energy consumption, which helps the family budget in areas where rationalism prevails. Every room has a thermostat installed, which enables temperature regulation between 5 and 30 °Ρ. Energy expenses are decreased by 5-6% when the temperature drops by just 1-2 degrees. There will be savings of 35–50% with a more adaptable approach to whole-house temperature control.

Any temperature schedule can be programmed with the EHU to control the heating system and determine when to disconnect a room or group of rooms if desired.

Advantages of the units

In recent times, energy-efficient water heating installations have gained popularity among Russians; they are relatively new to the heating equipment market. High technical qualities, environmental safety, independence, dependability, economy, and compactness pique interest.

  • Efficiency of EHU is 98% when two devices work simultaneously in the heating system;
  • the heating level is controlled by special temperature sensors;
  • compact size and neat appearance;
  • instant heating of the liquid in the chamber;
  • there is no need to coordinate the installation and subsequent operation with the Gostekhnadzor authorities;
  • significantly save owners" money during the heating season;
  • guaranteed service life is 10 years, declared by manufacturers operating period – 30 years.

Types of energy-saving boilers

Energy-saving electric heating boilers are becoming more and more popular as a heating option for homes, cottages, offices, shops, pharmacies, and other industrial, non-residential, and auxiliary spaces. It makes sense because energy resources are becoming more and more expensive; using energy-efficient boilers will result in lower energy costs.

Both of them and affordable gas boilers are in constant demand. Electric boilers for heating can be mixed or storage type, and they can be connected to floor, central, or individual heating systems with ease. Reduce the amount of electricity you use. Using a two-tariff electricity meter and turning on energy-efficient electric boilers at night will also help (the cost of 1 kW of electricity at night is much lower).

You can gain a lot of knowledge about electricity-powered heating boilers by watching this video:

The following characteristics are typically used to categorize energy-saving heating electric boilers:

  • type (electrode, induction, TEN);
  • place of installation (floor and wall-mounted);
  • power in kW (from 2 to 120);
  • the number of circuits (one-, two-circuit);
  • power supply method (single-phase, three-phase).

Only in situations where connecting to an electrical power source is feasible are energy-saving electric heating boilers used. If connecting to the gas mains is possible, economical gas boilers are utilized.

The flow of electric current through the liquid coolant, which is typically water, electrolyte, or oil, heats the space when using electric energy-saving boilers of the electrode type (also known as ionic or ion-exchange).

The disordered motion of liquid ions traveling from the cathode to the anode causes heating, and this chaotic motion causes the coolant’s temperature to rise quickly. Ionic type electric energy-saving boilers for homes are the best option when it comes to heating spaces up to 250 m2 or 750 m3, and they can reach up to 95 0C at the boiler’s outlet. They also take up minimal space.

The mounted heating economical electric boiler, which is regarded as the best, is seen in the video:

The image displays induction electric boilers, which use an inductor to save energy. The coolant is efficiently heated with its assistance. Its absence of heating elements, which positively affects its operation, sets it apart from other types of electric boilers for heating. In theory, it cannot malfunction and doesn’t require maintenance while operating.

Additionally, micro-vibration occurs inside the electric boiler during operation to stop scale from building up on the boiler’s internal components. The lack of detachable components in this type of heating boiler greatly increases its lifespan.

These energy-efficient electric boilers are not cheap; in fact, their price is several times higher than that of other models’ economical electrode electric boilers. However, the cost is reasonable, since this type of electric boiler requires no maintenance during operation and has a long service life.

The photo displays an energy-efficient electric boiler that draws attention with its unique design.

Coolant in TEN electric boilers is heated by the energy already present in the heating element device, which is connected to the power source.

The most popular type of electric boiler, which features tubular heaters (TENs), is depicted in the picture. TEN boilers are not expensive, to be sure. Numerous manufacturers produce them, and competition drives them to find ways to cut costs without compromising the electric boiler’s quality of work.

Overview of the most famous manufacturers and prices for electric heating energy-saving boilers

There are many well-known electric boiler brands in Russia. However, we will attempt to review the most well-known of them today, which must be domestic production. Of course, it was possible to include international brands in the review, but it is disappointing that they are so much more expensive.

Domestic brand: electric energy-saving boilers "Galan"

A well-known manufacturer of affordable, high-quality equipment. Of course, some customers are not overly happy with the company’s offerings, but in this case, you should be aware of the particulars of using electrode boilers. A little salt added to the coolant will help it function more efficiently, according to knowledgeable people.

The most widely used model is the "Galan Ochag-2" with a temperature regulator.

Incredibly significant! Additives should not be added without careful consideration and understanding. It’s preferable to seek assistance from a knowledgeable person.

Rising in popularity, the cost of which is falling annually. We will discuss the most well-known device models and brands in the content, along with their benefits over one another.

General energy saving measures

It would be deceptive to choose the heat source in isolation from the other components in order to achieve the best energy consumption. Several steps should be taken as a whole:

  • To insulate the building, bringing the heat transfer resistance of all exterior walls and other enclosing structures at least to the values corresponding to the modern requirements of normative documentation on construction.
  • To arrange the supply of outside air to the building, to organize its metered supply. This is necessary to ensure that the heat energy produced by the boiler plant is rationally used for heating the outside air.
  • Maximize the use of automation to regulate the microclimate parameters in the premises during the stay of people in them and when they are absent.
  • Use energy-saving heating systems for heating, e.g. underfloor heating or air heating with heat recovery function.
  • In order to achieve high environmental performance, it is preferable to use equipment using renewable energy sources.

After carefully examining each point, it is clear that conserving energy resources is an expensive endeavor. It’s true that capital expenditures for technical re-equipment are quite substantial. However, over many years, your operating costs will be significantly lower if you select an energy-efficient boiler while keeping in mind all of the aforementioned measures. Additionally, less powerful heating equipment will be needed for "warm" houses. This implies that when choosing a heat source, you will already be saving money.

It is useful to categorize heating units into groups based on the kinds of energy resources they use in order to select the most cost-effective ones:

  • electric heat generators;
  • Energy-saving boilers on solid fuel;
  • hot water gas units.

As a point of reference, only one of the three heater groups makes use of biomass, a renewable energy source. These heating units run on solid fuel; other heating installations function by burning hydrocarbons or using radioactive elements, both of which have non-renewable stockpiles.


To begin with, electric boilers are a common heating solution for spaces without gas appliances. They have shown their worth in heating individual residences; in addition, this kind of equipment serves as both an additional and primary source of heating in apartments.

The choice to heat an apartment as a backup heat source with an electric boiler

Energy-saving boilers are becoming more and more popular among users of different types of heating thanks to their operating principle and equipment’s versatility. The primary benefits of using

  • Silent operation and environmental friendliness.
  • The use of quality materials, that increase the service life.
  • efficiency of work with compactness of the presented models. The boiler is installed in any room, as it does not require an additional technical room or special ventilation.
  • Most of the options offered on the market have long warranty period, that allows you not to worry about the need for self-repair or complete replacement of equipment.
  • If necessary, a variant is selected that has numerous additional functions.

EVAN Warmos-7,5/380V electric boiler connected with smooth regulation

  • Automation is based on reliable electronic systems, capable of independently regulating the necessary level of heat exchange, which reduces the likelihood of breakdowns and malfunctions.
  • If a powerful heating system is required, you can pick up a models with high efficiency and good production capacity, but it should be understood that each model has limitations on the area of full-fledged heating. Most powerful options have such a limit is 80 m2.

Considerations like the amount of use and the requirement for hot water heating should be taken into account when selecting a boiler for a home. When comparing single-circuit and two-circuit versions, the cost of the latter is always lower at the same capacity.

In a private home, two-circuit boilers are frequently utilized for the entire heating system. Boilers with single circuit designs serve as both the primary source of heat and an additional form of heating. Boilers with high efficiency let you keep the room at a specific temperature and warm the air completely.

An illustration of where to put an electric boiler with two circuits

A number of crucial aspects of personal heating should be considered when selecting an appropriate space heating system:

  • functionality and size of the room;
  • construction and design of the equipment according to the technical task of installation and connection of the boiler in a particular room;
  • the choice of manufacturer and a specific model of boiler in the optimal price range, which will meet all the necessary parameters.

Using this method will enable you to accurately evaluate all the technical specifications and select the boiler version that best suits homeowner needs. Additionally, the equipment’s life can be greatly extended by proper operation, condition correction, and timely maintenance.

Device and principle of operation

Electromagnetic induction produced by a copper coil heats the coolant in induction boilers.

There are two primary types of energy-saving boilers for electric heating: induction boilers and electrode boilers. The latter go by many names, such as ionic and ion-exchange, but their fundamental characteristics remain the same. Without the use of heating elements, induction boilers use electromagnetic induction to heat the coolant. thus producing quick heating and making a tiny electrical savings. It uses regular water as a coolant. You can find instructions on making an induction heater by hand in another review on our website.

These boilers operate on the same principle as traditional induction kitchen ovens, which use an electromagnetic field to heat food.

The foundation of electrode boilers, commonly referred to as ionic and ion-exchange boilers, is the direct heating of the coolant. Two electrodes are provided by their design, over which coolant flows, and the heating process takes place in an area known as the "ionization chamber." Water becomes ionized when an alternating current is applied, and the ions gravitate toward electrodes with opposite potentials. Additionally, because the current is alternating, the water heats up as a result of the ions’ fast movement.

The ions that form in the coolant of electrode boilers cause the coolant to heat itself.

Certain energy-efficient heating boilers, which operate on the electrode boiler principle, frequently operate on specially treated water that has been infused with salts and other additives. Consequently, the heating rate increases and the energy required for the ionic reaction decreases. As an illustration, consider the energy-efficient Scorpion boilers, which use this kind of coolant.

In comparison to other TEN and electrode boilers, Scorpion boilers’ equipment enables you to use twice as little electricity, the manufacturer guarantees. It’s true that using harsh salts can cause severe corrosion.

Automation, which regulates the coolant temperature and the air temperature in the rooms, gives energy-efficient boilers additional efficiency. Intelligent electronics regulates temperature automatically, turning on and off the heating in line with a predetermined schedule. It produces good results when used in conjunction with the electrode heating scheme.

While there are energy-efficient ones in the wild, they are rarely on the market. The outcome is a tiny mini-boiler or an analog of a gas two-circuit boiler since they employ the same standard and straightforward electrode scheme with an ionization chamber, in addition to heating elements or coils for water heating, an expansion tank, and a circulation pump.

Because of their complicated design and lower reliability, induction boilers are much less common.

Tips before buying

When making a decision to buy a heating appliance, the majority of consumers prioritize saving money on energy. However, it will be beneficial for them to become familiar with a few points that will help to improve the efficiency of their work before making a decision:

  • choosing a particular model of heating boiler, should be based on the area of the room, remembering the following rule: per 1 square meter of area should be used about 1 kW of power;
  • it is necessary to determine how often the owner will use the heating device. Get an answer to this question, knowing how often people will live in the selected room. If the boiler is purchased for seasonal use and maintaining a positive temperature in the house, then you can limit yourself to models that provide a set of standard functions. If the consumer is tasked with providing comfortable living conditions at any time of the year, then you should consider boilers from different manufacturers, including different modifications;
  • It is equally important that the automation corresponds to the needs of the owner. This parameter should be considered even before the final decision is made.

For this reason, you should consider an electric boiler’s technical features in addition to its price when making your decision. It is critical that they satisfy the needs the user has for the device.

Its correct installation must also be attended to. Thus, it is ideal that these tasks be completed by trained experts.

What types of energy-saving electric boilers can be

These devices can be categorized according to their design elements (electrode and induction) and installation style (floor or wall-mounted). Additionally, one or two circuits can be used to differentiate between the number of circuits. Let’s first examine the installation procedure.

Compared to wall-mounted boilers, floor electric energy-saving heating boilers are larger in size. If the premises have ample space and can accommodate the installation of an electric boiler, then this type of equipment should be selected. Usually, such equipment is assigned its own room. The wall-mounted model is smaller and more space-efficient; it can be installed in any bathroom.

The "Galan" electric boiler model range is rather extensive.

It is evident from design features that induction electric boilers are not as common. Its inapplicability in open heating systems is the cause of this. But these devices have a lot of indisputable benefits. For instance, oil can be used as a coolant in induction boilers. Furthermore, the lack of limescale formation is significant. It is worthwhile to delve deeper into the electrode equipment, though.

An article about the subject:

In certain circumstances, such as when there are no nearby gas mains, using a gas system is not feasible. It is advised in this situation to make a decision after carefully weighing all of the options. In this review, we will carry out this task.

Operating principle

In other words, EHU functions as a direct-acting device. It doesn’t contain any intermediary components. The movement of ions between two electrodes at a frequency of 50 oscillations per second powers the water heating boiler. Additionally, the liquid heats up because any chaotic movement of electrically charged particles releases thermal energy.

The heated liquid rushes upward through the direct feed pipe of the electrode boiler, creating a significant temperature differential at the inlet and outlet that can reach a height of 25–30 meters (depending on the boiler model).

The units run automatically, and a special sensor that is linked to a relay regulates the temperature. Period of continuous operation: 2 to 9 hours. Because of its small capacity, the unit’s heating chamber helps the coolant heat up to 95 °C instantly.

EHUs can be used as a primary or secondary heat source and are intended for use in closed buildings of all kinds.

As a heat transfer medium, rainwater, melted water, and liquids resistant to frost can all be utilized.

A pump for water circulation can be used with or without the boiler. There will be a decrease in power consumption in the first scenario. A thermoregulator regulates the EHU’s operation by connecting or disconnecting the unit in response to variations in air temperature. As a result, a set temperature is maintained in the room.

Examples of the use of installations

Electric heating systems that use less energy are the best choice for business pavilions and stalls that are situated far from heat sources.

The condition of historic buildings in urban areas will benefit from the use of electrical installations, as it is not appropriate to undertake costly and time-consuming work to install heat lines. Ultimately, these kinds of mansions and historic palace structures are frequently encircled by exquisite parks. Energy-efficient installations might be the best course of action in these situations to preserve historic districts.

EHEs can be used as backup equipment in urban apartments. When the heating is turned off on chilly days—which happen frequently in the spring and fall—they offer a comfortable place to live. Because the Russian winters are long and severe, EHUs automatically heat the air to the necessary temperature during particularly important times when the centralized system is unable to provide enough heat.

Large spaces with inadequate thermal insulation, such as warehouses, production halls, exhibition halls, concert and sports event halls, can benefit from the use of EHUs as backup heating equipment.

Electrode heating boilers and their features

It is not surprising that this type is the most prevalent. The majority of older private sector homes have open heating systems. And if you can only install electrode equipment, what good is it to remodel the entire induction heater system?

The capacity of such a tiny electrode boiler is 5 kW.

Here, the heating method is electrolysis. The three electrodes in the middle, which are connected to a voltage of 380 V each, receive "phase" power while the boiler itself is connected to "zero." It turns out to be something akin to "army" or "student" boilers. In contrast to heating elements, these kinds of systems are the safest. After all, a closed electric heating element (in the event of an automation failure) can just blow up in the event of a water outage. Equipment using electrodes is free from these dangers. The absence of liquid in the boiler indicates a break in the contact, which will cause the electric boiler to abruptly shut off.

We invite you, our valued reader, to peruse one of the electrode boiler reviews for residential heating.

Gvoz4D, Russia, Ussuriysk: Enough eighth-grade physics knowledge is required for installation and start-up in operation, as well as the capacity to discern between phase and zero.

First and foremost, follow all instructions carefully, paying close attention to the heat carrier’s specifications. (*) Since the end of December until now, I have been using the electrode boiler known as "galan," and I am really happy with it.

I anticipate an increased bill for electricity, but it will be more likely a consequence of the game with salt in the water, as I set up the boiler "manually", that is, without a device measuring the load … Now we came to the calculated parameters and I have given up now this coal, this constant tension-top stove five months a year ..

Electrode boiler in the disassembly – there is nothing complicated in it

What you need to know before buying

You can save a lot of electric energy by investing in heating equipment that uses less energy. Nevertheless, when purchasing such a boiler, there are still a few subtleties to consider.

It is imperative that parameters like the room’s area be taken into consideration. One square meter should have about one kilowatt of power per unit.

Additionally, how frequently you use the boiler will determine which boiler you should choose. For instance, energy-efficient boilers with standard features would be appropriate if the operation is seasonal and the temperature must be maintained at +. Additionally, if you intend to occupy this space permanently, it would be wise to research the various boiler models available, as their functionality will increase. Selecting the ideal automation for you is also crucial. It is also preferable to select the mechanical or electronic control devices on your own, even prior to making the boiler purchase.

Electric installations

Since energy-saving electric boilers have the highest efficiency (98–99%), they should receive the most attention. This indicator is highly dependent on several factors, including the relatively low efficiency of the steam turbines used in nuclear and thermal power plants to produce electricity. However, since we are talking about the direct conversion of electrical energy into thermal energy, electric installations rank highest in terms of cost-effectiveness and efficiency.

Compared to other heat generators, a contemporary energy-efficient electric boiler offers numerous benefits.

  • The unit is very compact and takes up virtually no floor space;
  • does not require connection to additional utilities, except for the electrical and heating network of the building;
  • there is no inertia in the operation of the water heating unit, i.e. heating of the coolant stops immediately after disconnection from the mains;
  • simple design and high maintainability.

Another significant benefit of electric boilers is their easy combination—for obvious reasons—with any automation system (actuators, controllers, and sensors) for energy-efficient heating. There are three varieties based on how energy is converted into heat: conventional FET, electrode, and induction

All three types of devices have the same high efficiency, up to 99%, despite their different designs. Generally speaking, all electric boilers use slightly more than 1 kW of electricity to produce 1 kW of heat.

The biggest of all is the conventional unit, which consists of an electric heater (TEN) submerged in a metal vessel filled with water. The lengthy heating of the heating elements and the coolant, respectively, set it apart from the others.

The electrochemical characteristics of water, which cause it to conduct electricity, form the basis of the mechanism and apparatus of electric energy-saving boilers with two electrodes. As a result, when EMF is applied to electrodes submerged in water, heating happens. The heating medium heats up quickly at the same time.

The working principle of an electrode boiler

In induction heating systems, water also reaches a high temperature just as quickly. There, a coil with a metal core is housed in the vessel in place of electrodes. The coolant receives direct heat transfer from the coil’s eddy currents, which also heat the core.

The induction heating installation’s working principle

A major drawback of induction electric boilers is their high cost; aside from that, they are excellent appliances that can be used with any type of heating system.

Features of electrode boilers

Take your time purchasing an electric boiler. It doesn’t hurt to become acquainted with the features that this equipment possesses beforehand. Say, all customers should be aware that the quality of the heat carrier can have a significant impact on the installation process. This parameter directly affects how long and safely the heating system will operate. It is advisable to consult experts to ensure that the decision you make is the right one.

Furthermore, it’s critical to keep in mind that a good grounding is necessary for the regular operation of such a device, like an electric boiler that saves energy, and this should be considered during the installation process. This is just one more reason that boiler equipment installation should only be done by trained experts.

Only they are able to meet all the requirements and ensure that this device operates without failure for an extended period of time.

Some nuances of choosing a water heater for heating

When choosing the most cost-effective electric boiler for a home, it’s important to consider the level of intensity at which it will operate. Should you only need extra heating, two to three kilowatts of power should be sufficient. It’s important to think about whether a second circuit is required. Purchasing a two-circuit water heater for heating rather than a separate one for DHW will prove to be far more cost-effective if you require a hot water supply for your home. Yes, and there will be observable, significant savings throughout the operation process.

Although many people consider brand to be the most significant quality indicator, you shouldn’t take the words on the packaging at face value. These days, counterfeiting is very common. However, even if all the paperwork and certifications are in order, there might be a less expensive electric boiler with the same features right next to the counter. It’s also of comparable quality. The reason for this is overpricing "for the brand." The cost of the goods will increase with increased promotion, which may not always be justified by the equipment and quality.

Certain electric boilers are so small that they essentially blend in with the main plumbing.

What is the principle of operation

Experts claim that the most advanced heating system of recent years is the energy-efficient boiler, which provides high-quality heating while consuming less energy and money. Additionally, as resource prices continue to rise, consumers are forced to consider ways to cut costs. Private and rural home owners are starting to show interest in alternative heat sources, which can occasionally result in expensive expenses.

Energy-saving heating boilers have become extremely popular, mostly because they are simple to install and can be mounted on any electrified surface.

Users are also drawn to these devices because of their amazing design and straightforward construction. Utilize them in apartments as well as private homes and cottages; they blend in with any decor.

Ion efficient boiler

It’s important to note that the ease of installation of energy-efficient boilers—which can be mounted on any electrified object—has contributed to their increasing popularity. When comparing energy-saving heating boilers to TEN boilers, a 30% energy savings is achieved. Conventionally, these boilers are classified into the following categories:

  • Electrode;
  • Ionic;
  • Ion-exchange.

It is noteworthy that the aforementioned types all function essentially in the same way. The method used to transform electricity into heat is the only distinction. The following subtleties enable energy savings:

  • The inertia of heating is reduced several times;
  • The physics of the process of converting electrical energy into thermal energy;
  • Smooth start;
  • The use of automatic control of the temperature of the heat carrier and air;
  • Two-pipe system, which has efficient radiators;
  • Simplicity of construction with the use of the most modern materials;
  • Efficiency and reliability of operation.
