Inverter boiler for heating a house. Convector heating in numbers: how to heat a house and not go down the drain. How are devices classified?

Electric boilers are an excellent alternative. Inverter heating boilers are universal for all houses where there is electricity, and are completely independent of gas communications. No permit is required to install the equipment. Another advantage is the minimal amount of space required.

The downside of an electric boiler is the large amount of energy consumed. Modern developments of new generation boilers are aimed at increasing efficiency with minimal electrical energy consumption. New ones never stop improving.

Inverter electric boiler

Conventional electric boilers operate on the principle of heating. It heats itself and then heats the water. To implement this work, you need a place for water, a place for the heating element itself, protected from external influences. With this heating option, excess electricity is consumed, which significantly impacts the wallet.

Inverter boilers have a fundamentally different heating scheme. Everything happens thanks to electromagnetic induction. An alternating magnetic field creates conditions for the occurrence of an induction current. For proper operation of the boiler, it is necessary to convert direct current to alternating current. The inventory manager is responsible for this process. The inventory can be operated either from stationary sockets or from batteries.

Inverter boiler heating circuit

In practice, water from the heating system flows to an internal magnetic circuit, which passes current and creates a magnetic field. Thanks to it, heating occurs. Then the water again ends up in the heating system. There is a constant water cycle, which allows you to maintain a constant temperature.

Advantages:

• By heating water by increasing the temperature of the transformer winding, the heating rate increases. heating speed is several times lower.
• The heating element does not come into contact with water, so the quality of water does not affect the operation of boiler parts and increases their wear resistance.
• The heating element heats the water itself - which is a very energy-consuming action. The inverter boiler heats itself, saving energy

The heating element does not come into contact with water

Flaws:

• It is worth noting the high cost of inverter heating boilers. The cost of the simplest one is not less than 30,000 rubles.
• Product weight and size. The weight of a 2.5 W boiler reaches almost 25 kg.
• Can only work with .
• The pressure that limits work should not exceed 0.3 MPa.
• Complex control system

Installation of an inverter boiler

The organization of the heating system will depend on the purpose of the boiler. Boilers with higher productivity are required (). For small rooms or for a residential building, a household one is suitable. Self-installation of an inverter boiler can lead to poor quality work or damage to the device, so you should carefully and carefully plan all stages of installation and operation. Analyze whether the electrical wiring can withstand the increased load. An important element of safe work is. It will ensure the safety of the system during unexpected power supply fluctuations.

The boilers have an electronic function. Only professionals can handle bookmarking a program on their own, but once you install the program, you can forget about it for a long time.

Thus, we can say that the modern market has stepped into a new stage of heating devices - inverter boilers. The choice of this type of heating must be agreed with specialists. The boiler's performance is so high that it can provide heat to huge industrial areas in the shortest possible time.

As they say, “nature has no bad weather.” But, you must admit that sometimes it’s better to observe good weather through a closed window, being even on a frosty sunny day in a warm and comfortable room, realizing that the cost of heating your home is an order of magnitude less than that of those who organized a heating system “by the old fashioned way" (using electric or gas boilers for this).

Not bad – right? It turns out to be a kind of idyll in which, if desired, anyone can immerse themselves. The main thing is not to lose sight of effective innovations and introduce them into your life at the first opportunity. But only proven innovations. After all, the safety of you and your loved ones comes first.

Let's take, for example, Ballu heating convectors - branded products for which there is strong demand today. Many people do not even suspect how tangible benefits can be obtained from their use, although money savings can be seen already at the stage of equipment installation. And most importantly, these are not just words, but confirmed facts: the Ministry of Emergency Situations confirmed the safety of the device, and ROSTEST conducted research and proved that the indicated energy efficiency savings are not fiction. But more on that later. We recently wrote about. This time we decided to compare the efficiency and cost of heating with inverter convectors and traditional heating methods

Costs for the construction and operation of a heating system with an electric boiler

Currently, many owners of private households are inclined to use electric heating systems. There are several reasons for this:

• lack of developed gas supply networks near a construction site under construction or already in operation.
• practicality and ease of management;
• availability and relatively low cost of heating boilers.

Having planned the construction of a heating system, the “heart” of which is an electric boiler, owners of private households are well aware of future operating costs. We are talking about high energy costs for heating the coolant liquid. This is an inevitability that anyone who decides to install a seemingly inexpensive electric boiler will face.

For your information: an electric boiler with minimal functionality and capable of heating a house of 100 m² can be bought today for 5,000...8,000 rubles. But are the costs of organizing heating systems with electric boilers really “democratic”? Let's look at an example:

• the cost of a completely ordinary electric boiler is 8,000 rubles, while the cost of good branded equipment averages 40,000 rubles;
• the purchase of consumables and additional equipment (towel rails, pipes, fittings, etc.) for a house with the specified area will cost approximately 45,000 rubles. (this is the average cost, which may differ depending on the ambitions of the manufacturer);
• the cost of installation work is 64,000 rubles. (prices of the electronic service for selecting masters).

Total: 149 thousand rubles.

As you can see, the cost of installing radiators, pumps and other equipment completely destroys the optimism that the owner of the house may have due to the low cost of electric heating boilers.

Now let's calculate the costs of heating the premises. The average energy consumption of a system with an electric heating boiler in the cold season is 116 kW per day (we are talking about houses with an area of ​​100 m²). Minimum cost of one kWh. electricity in the second half of 2018 for the Moscow region is 3.77 rubles. This is data on a single-rate tariff for private houses located on the territory of gardening and other non-profit associations (information taken from the official website of Mosenergosbyt JSC). Other categories of consumers pay higher tariffs for electricity.

After simple mathematical calculations, we get: the minimum cost of electric heating costs is 13,119 rubles. per month.

Gas heating

Things are not much better with gas heating. The costs of its construction are comparable to the costs of organizing electric heating (with an electric boiler and liquid coolant).

But if you are “lucky” to purchase a plot that is located in an area with poorly developed engineering infrastructure, add to the total costs the costs of connecting a gas pipeline to your home (the cost of gas pipelines, the cost of developing design documentation and other inevitable expenses). For the Moscow region this is:

• costs for design and approval of project documentation with its subsequent registration - 20 thousand rubles;
• installation of gas pipelines - from 3 to 50 thousand rubles);
• tie-in into the gas supply pipeline – 30 thousand rubles;
• commissioning of a gasified facility with the participation of supervisory and control organizations - 50 thousand rubles.

To this should be added the cost of obtaining the necessary permits, approvals and technical conditions (which, by the way, are also needed when building a classic heating system with an electric boiler). In the end, this is plus another 50...100 thousand rubles (according to the most conservative estimates).

Total: 149 thousand rubles. (heating installation) plus 250 thousand rubles. (gasification of the site). We receive a “tidy” sum, which is close to 400 thousand rubles.

There is no doubt that if a person managed to buy a house already gasified, then he was really lucky. Indeed, in cold weather, the average bill for gas heating in the Moscow region in the winter of 2018 ranged from 6 to 8 thousand rubles. (we are talking about houses with an area of ​​100 m²).

Cost of installation and operation of Ballu convector heating with inverter control unit

Now let’s look at what prospects the installation of Ballu convector heating opens up.

To heat a house with an area of ​​100 m², you will need at least 4 convectors with a power of 2 kW. The heating area for which each such device is designed is 25 m². Of course, in practice, the heated area largely depends on energy losses, but if the design of walls and other building structures comply with climate standards, energy losses in all cases will be insignificant.

We open the manufacturer’s website and see that the cost of the Ballu Evolution heating module is 3,390 rubles. Equipping the module with an inverter control unit will cost another 2,390 rubles. So, the total cost of one inverter heater is 5,780 rubles. Not cheap for an electric convector, if you make a comparative analysis of other models on the market. But if we compare the energy consumption of another convector of similar power, equipped with a mechanical thermostat (conventional and inexpensive), it becomes clear that they are simply not comparable. Moreover, the difference in cost in the case of using the first convector will pay off in 1 – 2 months of operation.

Let's calculate the total costs of purchasing equipment for heating a house of 100 m². For the purchase of four convectors costing 5,780 rubles. you need to spend 23,120 rubles.

This concerns direct costs. With installation, everything is quite simple: since we consider convectors as the main heating, the default installation method will be wall-mounted. We hang it under the windows - by analogy with water heating radiators. Wall mounts, as well as a mounting template for drilling holes, are included in the equipment kit. To perform installation work, you will need a level (or an ideal eye), a drill and a few minutes of your own time, which will have to be spent on installing each convector.

If you don’t want to do everything yourself, then installing one convector will cost up to 1,500 rubles (these are the current prices for an electronic service for selecting craftsmen for construction and repairs).

• do-it-yourself installation cost – 0 rub.;
• the cost of professional installation is 6,000 rubles.

To summarize: purchasing and installing convectors will cost you 29,120 rubles. This is exactly how much you will need to pay to quickly and without headaches start heating up. The time you will spend on installation and connection will not exceed 1-2 days from the moment of purchase to the moment it is plugged into the outlet. This takes into account the delivery of 4 packages of equipment from the store in a personal vehicle and the search for a specialist or drill (for self-installation).

What about the cost of heating?

In accordance with the results of testing by the Rostest laboratory, the energy consumption of a convector with an inverter control unit with a power of 2 kW was 3.611 kW per day. Let's convert this into rubles and get 13.61 rubles. In the same test, a convector of the same power was tested, but with mechanical control. The energy consumption of this convector was 17.05 kW per day. We convert into rubles and get 64.27 rubles/day.

If we discard the fact that the maximum electricity is consumed in the process of reaching the set temperature (and not in the process of maintaining the set temperature) and simply record the energy consumption indicators for 30 days, we get 108.33 kW, which in rubles is 408.40 rubles.

As you can see, if the problem comes down to finding economical and efficient heating, the benefits of installing Ballu convectors become obvious even to non-professionals. It is especially relevant for owners of non-gasified houses and plots.

Let's complement the advantages of Ballu systems with their performance characteristics.

Savings by using an inverter unit

A unique innovative development that comes with the new line of Ballu convectors is the EVOLUTION TRANSFORMER SYSTEM control unit. Digital INVERTER technology expands the capabilities of the device with two additional options:

1. SMART EYE option on the presence sensor meringue. The SMART EYE sensor monitors the situation in the heated room and puts the convectors into sleep mode if there are no people or animals in the room.
2. SMART WI-FI option. Its key component is a removable element that allows you to control the system from anywhere in the world. The SMART WI-FI accessory allows you to combine several heating devices into one intelligent system. We are talking about a system capable of monitoring the status of each individual device and changing its operating parameters in accordance with programmed modes. In the case of a convector, these can be individual temperature values ​​for individual zones of the room. All that is needed to set up custom SMART WI-FI settings is the SMART WI-FI working module itself and a special mobile application. After entering the necessary parameters into the device’s memory, the system can operate without requiring additional human control.

The functionality of both options is very similar to the functionality of a smart home. Their key tasks are: optimizing operating costs, quickly achieving the set temperature, and ensuring operational comfort while maximizing energy savings.

This is very eloquently reflected by the results of a comparative analysis of two different convectors - one inverter, with a digital INVERTER control unit, the other - conventional (with mechanical control).

Innovative design of heating elements

All devices in the new line of Ballu convectors are equipped with patented heating elements made using HEDGEHOG technology. And this is what this means: thanks to the special geometry of the heating elements, the heat transfer area of ​​the device increases by 20%. This improves the performance of the convector and increases the speed of heating rooms by an order of magnitude (in comparison with similar devices from other manufacturers).

In general, the unique shape of the body and fins of the heating unit allows you to spend 30% less time heating rooms of the same volume. At the same time, spaces with excess temperature do not form inside the device, which prolongs the service life of the equipment and prevents overheating of its outer casing.

The safety of Ballu convectors is confirmed by the certificate of conformity of the Ministry of Emergency Situations, and their quality is confirmed by the impeccable reputation of the manufacturer.

Let us highlight the main advantages of Ballu convector heating systems:

• Economical
• Safety
• Efficiency

Here you can add undeniable benefits regarding construction and operating costs. Of course, we must not forget about the possibility of equipping the device with a WI-FI module, which allows you to control the convector through an application from anywhere in the world, maintaining the specified temperature in the house in your absence.

We remind you: by choosing innovative solutions from trusted manufacturers, you are one step ahead of those who sincerely want to save money, but still benefit from the technical advances of previous decades.

During the cold season. Electricity is available in every home, so setting up such a heating system is not difficult. But heating a house with electricity will be expensive compared to other systems. In order to save money, inverter heating boilers were developed. They have high efficiency and heat loss is minimal.

Operating principle of an inverter boiler

Standard electric boilers operate on the principle of transferring energy to a heat carrier. Transmission is carried out using heating elements. If the equipment has a heating element, then you should provide in advance a place for heating water, protecting the heating element from corrosion and taking into account possible heat losses.

Inverter electric boilers operate on a different principle. It works using electromagnetic induction. To operate this system, it is necessary to convert direct current into alternating current from the electrical network. The inverter runs on batteries or mains power. With the help of an alternating magnetic field, the process of generating current occurs.

An inverter electric boiler can have 2 circuits:

1. A heat exchanger that heats the coolant.
2. Magnetic, which generates an alternating magnetic field.
3. When an alternating current is applied, a magnetic field is created using a coil. Thus, the water in the pipelines is heated.

Organization of the heating system

Inverter boilers are divided into several types depending on power:

• Domestic boilers. The equipment is compact in size. A household boiler can operate from batteries or from the mains.
• Industrial boilers. The equipment is large in size and has high power, a complex current conversion process, and a large-volume heat exchanger.

It is necessary to make a design for an inverter-type heating system before organizing it. You also need to arrange wiring with a large cross-section. Since when the boiler is operating, the load on the electrical network increases.

Advantages and disadvantages

The following advantages can be identified in an inverter heating boiler:

1. Since the heating element does not come into direct contact with water, the requirements for the chemical properties of the coolant are underestimated. The winding acts as a heating element in the inverter boiler. The chemical composition of the coolant depends only on the properties of pipes and radiators.
2. High performance characteristics are high. Since there are no heating elements.
3. If a centrifugal pump is installed in the heating system, the heating rate of the coolant will become higher.

But inverter boilers have several disadvantages:

1. The need for a complex electronic control system. It is needed to regulate the power of the equipment.
2. High price. Heating element boilers are much cheaper.
3. The boiler is heavy and large. In order to heat a large room, it is necessary to use a large heat exchange chamber. And also the number of turns in the coil should be increased.

But, despite the minor disadvantages, such boilers are increasingly gaining popularity.

Heating system design

Before choosing a heating system, you need to think in advance what equipment you will use. In an inverter heating system, it is necessary to select equipment with a power that will correspond to the size of the house. But heat loss should be taken into account, so choose a power slightly higher than required.

In order to heat 10 sq.m. a house located in average climatic conditions requires 1 kW of heating device performance. But such calculations are considered indicative. Therefore, you should calculate the required power yourself.

But for high premises, such as industrial buildings, 1 kW of performance is needed to heat 2 cubic meters of air.

Peculiarities

After you have calculated the required power, you must select the type of electrical connection. It can be single-phase or three-phase. In order to heat a small country house, 10-12 kW of power is enough. A single-phase electrical network is suitable for such a house. And three-phase is suitable for inverter boilers that have a power of more than 6 kW. Such heating boilers can be connected to a network with a voltage of 220 or 380 V. Such devices can be used without installing an additional circuit.

Industrial-type boilers are usually used to heat industrial buildings and premises. They are large in size, have a volumetric heat exchanger and a complex current conversion system. Household inverter boilers are used to heat private houses. Since they are small in size and low in cost.

Points to consider during installation

Inverter boilers can be used in pressure and gravity heating systems. Since the heating rate of the coolant is high, a device should be installed that will dose the water supply to the pipeline system. Consequently, the efficiency of the device will increase and the need for new heated liquid will decrease.

Before you start installing the system, you need to check whether the existing electrical wiring is suitable for connecting the new heating equipment. If the electrical wiring does not match, then you need to replace the wires with new ones that have a larger cross-section.

In a three-phase electrical network, it is necessary to run additional cables from the general network. If a sudden voltage drop occurs in the system, a special protective unit will stop the operation of the equipment. Therefore, it must be installed.

Before installing an inverter heating boiler, you should not forget about some points:

• About equipment grounding;
• The boiler must be located at the required distance from furniture and other objects in the house;
• A special air release valve must be installed in the heating system;
• If your system is not free-pressure, then you need to install an expansion tank. It is needed for circulation of the pump and to compensate for the expansion of the coolant.

When using a GSM module or a special electronic programmer, you can ensure a comfortable atmosphere in your home, even during a long absence. This option is great for those who come to a country house only for the weekend.

Easy to operate and practical to use, electric heating boilers remain in demand among residents of apartments and private houses, even despite rising tariffs. Such boilers are installed without obtaining a permit and can be of any power. To reduce maintenance costs, an inverter is installed for the heating boiler. In this case, the models are called inverter and differ from standard products in many advantages. Let's take a closer look at all the features of the units.

What are inverter heating boilers?

A standard electric boiler operates from heating elements located inside the housing. The coolant receives heat, which it then transfers to network devices. The power of electric heaters determines the heating mode of the coolant. An inverter heating boiler operates on the principle of magnetic induction - water or other coolant does not come into contact with the heater, so the devices have an impressive service life.

An inductor is needed to convert direct current coming from the network into alternating current. The equipment is installed in gravity, pressure heating systems; the device increases the rate of heating of the coolant; therefore, installation of a liquid dosing unit is required to reduce the device’s need for a heated substance and increase the efficiency of the model.

On a note! Before purchasing an inverter boiler, you should check the endurance of the electrical wiring. Some types of models require a three-phase network, for which a separate cable is provided from the distribution box. An additional protection unit will help with power surges.

Design and principle of operation of an inverter boiler

The design of the equipment looks like a three-circuit diagram, in which all the circuits are nested within each other:

1. The outer contour is a housing with thermal insulation material. The sheath is needed to prevent heat leakage and prevent user contact with the wires.
2. The middle one is an induction coil wrapped around an internal circuit. Winding insulation limits the transmission of high-frequency current; all mass flows only to the wires. The coil can be made in a cylindrical or toroidal shape. The toroidal shape is two tubes made of a ferromagnetic steel alloy and wrapped with wires. The pipes are located at the bottom and top of each turn. The mass of a toroidal coil is lower than that of a cylindrical coil, but the efficiency is higher.
3. The inner casing is a sealed cylinder, inside of which the coolant is heated. Two pipes extend from the cylinder - one for transporting water into the network circuit, the second for the return flow of liquid for heating.

The circuit includes an inverter (current converter), a temperature sensor and an automatic electronic control system. The principle of operation is not complicated - when mains current is supplied, the inverter converts direct energy into alternating energy, then an induction current is generated through a magnetic field, which is used to operate the boiler and heat water.

Important! Rapid heating of the coolant reduces energy costs, which is why inverter boilers are considered the most economical type of electric heaters. Low-power models consume little electricity and operate on mains power or batteries.

Types of inverter boilers for heating systems

There are two types of equipment - industrial and household models.

The differences are as follows:

• the industrial boiler has increased heat exchanger parameters, a complex system of current converters and high power;
• household inverter electric boiler is a compact device, equipped with a toroidal coil, powered by mains and batteries.

The performance of domestic boilers is lower than that of industrial boilers, but they are cheaper, more convenient and easier to operate. Inverters for gas boilers are available for sale, in which a circulation pump is installed. These are high-power, volatile devices in which installing an inverter will reduce maintenance costs.

Advice! When choosing an inverter for a gas boiler, it is important to calculate the power of the connected energy carrier to take into account the starting current for the pump. To do this, the pump power is multiplied by 3, then by a factor of 1.2-1.3.

Additional power in the form of DC generators will not hurt. They are required if an inverter gas boiler is installed in regions with interruptions in the electricity supply - batteries will not help here, a generator will be useful.

Advantages and disadvantages of equipment

The main advantage of inverters is the reduction in maintenance costs for electrical appliances, but there are a number of other advantages:

1. Long service life. There are no heating elements or other heaters that can damage the unit.
2. Undemanding to the coolant. The induction coil does not interact with the filling; it is allowed to fill the network with antifreeze and tap water.
3. Low heating inertia. This quality increases the efficiency of systems with forced and gravity circulation of coolant.
4. There is no risk of corrosion since the water does not touch the steel elements. And the inner body of the cylinder filled with water is made of stainless material.
5. The ability to switch the unit to batteries guarantees warmth in the house during a power outage for any period.
6. The models are used in private houses, apartments, and are built into any heating systems without permits or inspections.
7. Manufacturers offer a wide range of devices with different dimensions and power parameters.

Inverter electric boilers operate very quietly; they do not have to be taken outside the living space. A home craftsman can assemble the unit if he has experience and simple tools. In this case, the boiler is formed with any required power, supplemented with pipes for the water storage tank, and other types of necessary parts for modernization.

Advice! Powerful models with performance ratings from 60 kW are installed in a separate room, for example, in a basement or boiler room. A separate cable is provided for power supply; the circuit is equipped with a control and protective response unit.

Induction boilers are more expensive than standard types of electric heaters. When choosing a device, it is important to calculate the performance indicator “for reserve”, this is approximately 5-15%. If the house area is large, the size of the model will also be impressive, because the number of turns of the secondary coil increases. One-time investments pay off with further savings on maintenance, ease of use and long service life of the devices.

Advice! Each unit is equipped with sophisticated automatic monitoring and control. Making changes to the factory settings will result in equipment failure. If you need to make adjustments to the operating mode, you should entrust the matter to a specialist.

Installation of an induction boiler involves a closed-type heating system with a circulation pump to ensure forced circulation of the coolant and an expansion tank.

The requirement for installing an induction boiler is strict verticality. The inlet pipe in induction boilers can be located at the bottom or on the side, for different models. The return pipeline of the heating circuit is connected to the inlet pipe, and the supply is connected to the outlet pipe (in different models it can be located at the top or in the upper level of the housing). Wall mounting is carried out taking into account the mass of the boiler and the coolant circulating in the boiler and through the pipelines. The fastening must be reliable, and the boiler must be strictly vertical. Distance requirements:

• The boiler body must be located at least 0.3 m from all surfaces (floor, ceiling, walls and any objects) relative to the side edges
• Likewise - at least 0.8 m from the top and bottom edges of the boiler unit

To connect an induction boiler, grounding is required. There is no need for piping made of metal; it is possible to connect metal-plastic pipes of the grounding loop to the boiler pipes. A safety group, consisting of a pressure gauge, an automatic air vent and a safety valve, is built into a local section of the pipeline in close proximity to the boiler outlet pipe. Then shut-off valves are placed along the way. The expansion tank is installed on the return pipeline. Behind the connection point of the expansion tank and before connecting the return pipeline to the induction pipe of the induction boiler, connections are made in the following sequence: a settling filter, a coarse mesh filter, a circulation pump and a flow sensor (to control the flow of coolant through the return pipeline and its passage into the boiler).

To connect the control system of an inverter boiler, it is mandatory to follow the electrical installation rules (PUE). All systems are connected according to schemes regulated by the technical documentation for the boiler (technical passport).

About choosing an inverter boiler

Domestic models of inverter units have the following versions: single-phase, power 2.5; 7.5 kW and more powerful - three-phase: from 8 to 65 kW. Heating systems with induction boilers include both mandatory elements and additional equipment with a control unit: an electronic mode programmer for up to seven days of operation or a programmer for remote control.

Induction boilers do not reduce power during operation, so a modification is selected based on the initial data of the heated area. But in order to accurately assess the need for boiler power and thermal parameters for a particular house, you need all the information about the insulation of building envelopes and ventilation systems. You can preliminarily determine the minimum boiler power using the proportion: for 10 m2 a power of 0.6 kW is required. Example: a room with an area of ​​18 m2 requires a boiler installation power of at least 2.65 kW for heating.

Manufacturers provide a 36-month warranty on induction boilers, both for the boiler unit itself and for the electrical equipment. The main point for a long and reliable service of induction boilers without accidents and repairs is the magnetic core element. The thickness of the pipe wall is important, since the metal will be subject to corrosion one way or another. Pipes for cores are thick-walled - with a wall thickness of at least 1 cm.

Technical characteristics and advantages of induction boilers

• There are completely no moving, loaded, rubbing parts, as well as heating elements. As a result, there is no wear, no need for periodic replacement of parts, etc.
• It is possible to connect and operate in normal mode from DC power networks and at low voltage. As a rule, electric boiler models do not have such capabilities
• The design of the induction boiler has no connections with connectors, which eliminates coolant leaks
• It takes much less time to operate and heat up to operating parameters when compared with all other types of electric boilers
• The design and operating features of the boiler provide the advantage of preventing scale deposits of salts on the internal surfaces of the magnetic core core. Firstly, the heater and coolant fluid have a slight temperature difference - up to 30 degrees. Secondly, the operation of the boiler involves high-frequency vibrations caused by eddy currents arising in the core, which “repel” ionic salt particles from the metal of the pipe core
• High class for electrical safety and fire safety (second class). The electrical connection between the inductor primary winding and the heater-core in the design of the induction boiler is structurally excluded, and the heating of the coolant and the magnetic core pipe has an interval of no more than 30 degrees
• Inverter boilers do not require fuel, smoke removal and chimneys, as well as their cleaning from soot - as for all electric boiler units
• No need for a separate boiler room and collecting permits to connect the boiler
• Like the vast majority of electric heating devices, the inverter boiler has an efficiency close to 98-100%, and there is no decrease in power and efficiency during operation, which distinguishes the induction device from electrode and heating elements
• Manufacturers claim that the average service life is a quarter of a century or more, and no maintenance is needed. The thicker the wall of the metal core pipe, the lower the risks of corrosion processes and the more durable the unit
• There are no special requirements for the chemical composition of the coolant. It is possible to use water, oil, antifreeze and other liquids; their preliminary preparation and cleaning is not required, and the coolant lasts for about ten years before replacement
• Induction boilers operate absolutely silently
• Low inertia, which saves energy (heating element heaters have much greater inertia, but electrode boilers have even less inertia than induction boilers). The energy efficiency of induction boilers is due to the use of electronic control. Energy consumption is less because the temperature is regulated at a certain minimum, and when it increases, the control elements disconnect the boiler from the power supply, and reconnect as soon as the temperature drops below the level set by the user
• For installation work on installing the boiler, it is not necessary to involve highly qualified specialists
• The boilers can be used for all closed-type heating systems, including underfloor heating and baseboard heating systems, since the minimum threshold for heating the coolant is only 35 degrees
• The maximum permissible pressure for a heating system powered by an inverter boiler is 0.30 MPa

The disadvantages of inverter boilers include:

• Considerable dimensions and weight. Parameters of a small single-phase boiler with a power of 2.5 kW: diameter 125 mm, height 0.45 m and weight more than 20 kg
• The main part of the control system - the inverter starter - determines the considerable cost of the boiler. Prices for inverter boilers today are considerable
• Inability to use in open heating systems
• The presence of difficult-to-screen interference within a radius of several meters from the boiler location. The boiler generates long, medium and VHF waves. The human body does not perceive or react to these waves in any way. The reaction of domestic animals to the operation of induction units was observed, also within a radius of up to ten meters

One of the additional advantages of using an induction boiler in the heating system of an individual house or cottage is that it is possible to maintain an optimally comfortable temperature in a home in which people do not live permanently, but come for a while. Such operating conditions do not require powerful boiler models, since a 4.5 kW boiler can stably heat a house of up to 100 m2 with a constant temperature level of about 10-15 degrees. In this case, you can create comfortable conditions if you have a fireplace or stove. Such heating combinations are popular in areas with cold climates, as they provide both thermal comfort and certain energy savings.
