Positive and negative sides of the inverter boiler
There are a number of advantages that inverter installations have, including:
- increase in operational parameters as a result of the absence of heating elements;
- small inertia during heating, thus, in the presence of a centrifugal pump, the coolant will heat up faster;
- the operation of the system is not affected by the chemical composition of the coolant;
- the ability to install the device anywhere.
Like other heating systems, the inverter boiler has several disadvantages:
- rather high cost of inverter equipment compared to similar devices operating on heating elements;
- has an impressive size and weight, and therefore requires strengthening the base on which the boiler will be located;
- the device needs an electronic control system for subsequent power adjustment.
Despite minor shortcomings, nevertheless, inverter boilers are very popular among consumers and the demand for them is constantly increasing.
Inverter equipment device
The device of the vortex induction boiler
In fact, this technical solution is far from new, the phenomenon of electromagnetic induction, due to which electric induction heating boilers function, was discovered by M. Faraday back in 1831. Simply, thanks to modern materials and technologies, the phenomenon has been taken as a basis and implemented in water heating installations relatively recently.
Water heating occurs due to eddy currents (Foucault currents) appearing in the core of the coil. They are formed under the influence of an alternating electric field created by the turns of the coil with an alternating current with a frequency of 50 Hz. The core is made in the form of a pipe, and the coolant flows through it when heated. In fact, the device is an induction converter of electrical energy into thermal energy with an efficiency of about 98%. The diameter of the wire from which the coil is made, the number of turns and the dimensions of the core are calculated in such a way as to heat water up to a maximum temperature of 95 ºС and at the same time prevent overheating of the winding.
Advantages and disadvantages
The real advantages that induction boilers have for heating a house or an industrial building are as follows:
- High, as with all water heating installations, the efficiency of work, which is in the range of 97-98%.
- Durability due to no moving parts and simple design.
- Small dimensions that allow you to place heating equipment in a room of any size.
- High heating rate of the coolant and no inertia when it is turned off.
- Comfort during operation, an induction electric boiler does not require the constant attention of the owner of the house, and the frequency of its maintenance depends entirely on the quality of the water used in the system.
Vortex heaters are supplied with automatic control kits, which makes it possible to link heat generators with other climate systems in the home.
Sectional heater
This equipment also has disadvantages. The main one is the high cost, especially for heat generators of the Sibtekhnomash type. If it is quite acceptable to use these units for industrial purposes, then induction heating of a private house may turn out to be unreasonably expensive.
The experience of practical use of vortex heaters by homeowners and maintenance personnel of service companies is not very extensive yet, but at the moment there are no significant complaints about the equipment.
Features of an inverter heating boiler
An inverter heating boiler uses electric current in its work.However, in this device, it generates a magnetic field, which in turn contributes to the appearance of an electromotive force in the conductor. This conductor is located inside the circuit.
As a result, vortex flows arise in the device, which heat up the conductor material. As the frequency increases, the heat also increases. Previously, this type of boiler was used in the metallurgical industry and blacksmithing, because thanks to the induction field, it is possible to heat the workpiece to a predetermined temperature with high accuracy. In addition, similar structures were used in production for the purpose of heating rooms.
Depending on the power of the unit, it is connected to a single or three-phase network. In the first case, the power of the device does not exceed 10-12 kW. Typically, these models are used to heat a country house or a small private building. Three-phase designs are designed for performance over 6 kW.
Devices with a power of 6-12 kW are connected to an alternating current network with a voltage of 220 or 380 V. They can be operated without creating an additional circuit. Inverter-type units are allowed to be used in gravity and forced heating systems. Due to the high heating rate of the coolant, a device for metered water supply to the heating system is usually installed. This improves the efficiency of the device.
When installing inverter heating, the system must be equipped with an automatic air vent, expansion tank. In networks with forced circulation, pumping equipment is installed.
Device and principle of operation
The inverter electric boiler has three nested circuits:
- The inner contour is made in the form of a sealed cylindrical container. This is where the water is heated. However, there are no heating elements or electrodes inside the tank, but only a coolant. The circuit consists of two nozzles. The first of them is designed to supply heated fluid to the heating system, and the second is to return the cooled coolant back to the device.
- An induction electric coil acts as the middle circuit. It is wrapped around a container of water. Because all wires are insulated, no electrical current is transmitted to other surfaces. Only high-frequency current flows into a coil with a toroidal or cylindrical winding. The toroidal version of the coil consists of two pipes made of ferromagnetic steel, wrapped with wires. Pipes are installed at the top and bottom of the heating unit and inside each coil. The weight of the toroidal coil is less and the efficiency is higher.
- The outer contour is a body with thermal insulation. It is needed to protect against human contact with wires, and is also designed to prevent heat loss.
Also as part of the inverter boiler there is a temperature sensor, an electronic control circuit and an electrical converter. The last device is designed to adjust the characteristics of the electric current to such parameters that are optimally suited for the operation of the coil. Boiler inverters supply a current with a frequency of 20 kHz to the coil.
The principle of operation of inverter heating equipment is as follows:
- electric current goes to the converter;
- boiler inverters increase the frequency of electric current and its voltage to the required parameters;
- the converted current goes to the toroidal winding, as a result of which a magnetic field is formed and vortex flows arise;
- by means of an electromagnetic field, the currents go to the inner contour of steel;
- as a result of the interaction of currents with the circuit, the heat exchanger is heated, and, consequently, the coolant circulating in it.
Heating electric boilers for 220 V
What to consider when choosing a heating boiler:
- type of building;
- boiler price;
- stability of electrical networks and the ability to obtain the necessary power.
If the payment for the kilowatts used is not scary, and the electrical networks are stable and allow you to get the necessary power, and there is no central heating and gas in the place where you live, and there are also problems with installing a solid fuel device, then 220V electric boilers will help solve this problem.
Choose a 220V electric boiler according to the required power for heating a room of a certain area. The calculation formula is as follows. For 10m2, you need 1 kW of electric boiler power 220V with a ceiling height of up to three meters.

Why buy an electric boiler
There are many options for home heating. The choice depends on the availability of a particular resource, the terms of use. So the gas main can be located away from a private building. In this case, it will not work to connect the gas equipment. Heat generators operating on solid or liquid fuels need special conditions. To store raw materials, you need to allocate a certain place. In addition, constant monitoring of the operation of the unit is required.
In this regard, the electric boiler 220 is more practical and easy to maintain. Its installation is quite simple, the device works stably, does not take up much space. Of course, the cost of electricity is constantly rising. But this does not reduce the popularity of units of this type. Moreover, today there are energy-saving models.
Many owners of suburban areas prefer boilers powered by electricity.
Some models of these units can provide the room not only with heat, but also with hot water. Electric boilers are sometimes also installed in city apartments. It should be noted that an electric sauna boiler can also be successfully used. There are devices that can be controlled remotely. So you can turn on the boiler while still on the road, so that upon arrival the bath is already warm enough. Therefore, in many cases, electric heaters are an excellent alternative to other types of heat generators.
Inverter heating boilers as it does not stop working, pros, cons, photos and videos
In any case, but the use of electricity for heating is considered a new direction in today's world. Using inverter heating boilers is much more profitable and has a lot of good qualities. For example, electricity, unlike gas, is in any house and even a summer house.
Prospects for the inverter boiler
Using an inverter boiler is quite easy, due to what for its use does not require permission, they cost less than traditional devices, and are smaller in size. You can negate all the advantages of inverter boilers if you take into account the cost of electricity for some customers.
But the world does not stand still, and at the present time, work is underway to improve electric boilers. Big steps have been taken in the field of increasing their efficiency (hereinafter referred to as efficiency), and reducing heat losses. Based on these factors, it follows that inverter boilers are the most promising system at the present time.
How the inverter heating boiler does not stop working
Direct combustion boilers operate on the principle of heat transfer to a heat supply heat carrier using an electric tubular heater. As a result, when designing the boiler, it is worth considering the place where the heat carrier will be heated, and taking into account its protection from the penetration of the heat carrier onto the surface of the Tubular heater in order to eliminate corrosion. It is also necessary to provide and reduce heat losses.
Inverter boilers for heating are also called induction boilers. They work on the principle of electromagnetic induction. For this, an alternating magnetic field and a voltage converter are used, which will work both from an industrial electrical network and from a battery. A voltage converter is used to change from AC to DC. Due to the electric current, the inductor performs a magnetic field, and it, for its part, already heats the coolant in the heat exchanger, and then the rest is already moving in the pipe system.
Working diagram of an inverter boiler
Such boilers are mostly implemented in a double-circuit form:
- Magnetic circuit. It is used to generate an alternating magnetic field;
- Pipe coil. Such an element is used to heat the heat carrier.
Pros and cons of an inverter boiler
Like every product, inverter heating boilers have their own negative and positive sides.
Good points in the use of such boilers:
- Increased operating characteristics due to the fact that there are no parts for heating the heat carrier;
- Small inertia of heating the heat carrier. When using a circulation pump in the heating system, the speed of heating the heat carrier becomes significantly greater;
- The need for a thermal carrier and its chemical composition has been reduced. The component that heats the coolant is considered a winding. It does not come into contact with the heat carrier and therefore is not affected by it. Therefore, the composition of the heat carrier is determined by the characteristics of the heating pipes and heating radiators, which significantly reduces the cost of such a heating system.
Working scheme of inverter heat supply
However, there are also disadvantages of inverter boilers:
- The first and very important disadvantage is the price. Such a boiler will cost much more than its own rival on Tubular heaters;
- Very impressive dimensions. The more the room needs to be heated, the more the pipe coil is needed and, naturally, there are more turns of the inductor coil;
- To control such a boiler, a heating system is quite complex.
But, regardless of everything, the induction boiler will be available in the future to each client. And at this time, objects with systems of this type of heating are becoming more and more popular.

Separation of electric boilers by type of installation
According to their place of installation, electrical devices are available in two versions:
Floor options are used for large volumes of heating of buildings and structures. For small volumes, such as small apartments, private residential buildings, country houses, compact electric boilers 220V are used. They are hung on the wall. They take up little space. It is very convenient to operate them.
The design of the 220V electric boiler consists of two parts. This is a heat exchanger and a control cabinet. In the heat exchanger, water is heated by means of thermal heaters, the control cabinet allows you to control the performance of the 220 V electric boiler and maintain the specified parameters of the coolant.
Since the heating of objects using these 220V electric boilers is mainly of a closed type, many electrical devices have a built-in or additionally included expansion diaphragm tank. which compensates for the excessive pressure of the coolant in the network. They can also have circulation pumps for better distribution of the coolant with large volumes.
Temperature controllers and programmers can be installed, which allow more economical automatic use of the operation of an electrical device. Electric boilers 220 V are most often performed with one circuit. To obtain hot water, it is necessary to install an additional water heater, storage or instantaneous.
Advantages and disadvantages
The positive qualities of inverter heaters include the following:
- The unit can work with antifreeze or water. In this regard, it is significantly superior to electrode boilers, which can only work with liquids with good electrical conductivity (usually only water), so antifreeze is not suitable.
- The advantage lies in the low inertia of heating. In other words, the device quickly heats the coolant to the required temperature. When using a centrifugal pump, the heating rate increases significantly. All this allows you to quickly and effectively regulate the temperature of the air in the house.
- The impressive service life of the device is considered its main advantage. This is due to the fact that the induction coil does not come into contact with the heat transfer fluid, as it is well insulated. Boiler inverters, coil and automation have a large margin of safety. If untreated water is poured into the system, then over time plaque may appear on the walls of the water tank, however, there are no high requirements for the quality and purity of the coolant.
- No need to worry about the leakage of the coolant, because the case has increased strength and tightness.
- If we compare the fire safety that a gas boiler has, the inverter unit is much safer in this indicator.
- During operation, inverter equipment does not emit much noise, and its efficiency reaches 100 percent.
- The device has compact dimensions, which cannot even be compared with gas and solid fuel units.
- If desired, an inverter-type heater can be made by hand.
- There is no need to allocate a separate room for the installation of equipment. Also, it does not require any approvals and permissions.
- Due to the absence of a combustion chamber, it is not necessary to install chimneys.
- The device does not require professional installation and can work up to 25 years without breakdowns.
Among the shortcomings, it is worth mentioning the greater weight in comparison with other models of electric boilers. With these parameters, the boiler power will be average. For this reason, they are not fixed to the wall, but are installed only on the floor. The price of such a device is higher than that of its electrical counterparts. These units can only work in closed heating systems.
Complex electronics are needed to adjust the heating mode and control the operation of the device. It is the cost of the control system that determines the final price of inverter-type heating equipment. During operation of the unit, electromagnetic interference occurs that may affect the operation of other electronic equipment.
Economic electric boilers for home heating types
Various reasons force to organize heating in the premises, resorting to electric energy. First of all, this is prompted by the remoteness of buildings from main gas pipelines and the inability to use liquefied gas. Sometimes this is dictated by considerations of efficiency, because the creation of a parallel source for heating the coolant at night with the help of electricity significantly reduces the cost of space heating. An electric boiler, if necessary, can solve the issue of heating autonomy of some part in a large building (floor, building). This option is considered in case of discrepancies in the requirements of the temperature regime in the premises of one building by different owners or tenants of the premises. Most often, electric boilers are used by homeowners to create comfort and coziness in country houses or summer cottages (for more details: "Electric heating boilers for summer cottages: comfortable heating").
Electric boilers according to the principle of operation and design are divided into three types. We list them in order of prevalence:
- heating elements (a thermoelectric heating element is used);
- electrode (the coolant reacts with the electrode and heat is released);
- induction (based on an inductor).
Boilers that use electricity to generate heat energy are classified according to their location: wall-mounted and floor-standing. The main characteristic for their systematization is the rated power. It varies from 3 to 60 kW. When determining the power of an electric boiler for heating a private house, a proportion is used. 1 kW of power allows you to maintain a temperature of 20-23 degrees Celsius on an area of 10 square meters. meters at a height of 2.5 meters. The error in the complexity of the heating system, the degree of insulation of the building and the decrease in boiler performance during long-term operation does not exceed 10%. Thus, to heat a private house with an area of 100 square meters. meters, it is necessary to use economical electric boilers with a capacity of 12 kW and above. This formula undergoes changes when calculating for electrode boilers.
Inverter heating boilers working principle, pros and cons
Using electricity for heating has many good qualities.So, if we compare a system of this kind with gas heating, it is noteworthy that there is electricity in any house. For an electric boiler, no permit is needed, such boilers are small, and their price is less. Of course, the cost of electricity for some customers can completely remove the pros. However, at present, developments are aimed at increasing the efficiency of boilers and reducing heat losses. And the most promising system in this case is inverter heating boilers.
Inverter heating boiler
Basically, if we consider traditional electric boilers, then here, the working principle is that energy is transferred to the heat carrier using a tubular heater
So, if the design has a tubular type heating element, then it is also necessary to take into account an individual place in order to heat water, protect the tubular heater from the rust process, and also take into account heat losses
Inverter (or electromechanical) heating boilers operate on the principle of electromagnetic induction.
So, with the help of an alternating magnetic field, an induction current is generated. In order for this process to be implemented, it is necessary to convert direct current from the mains into electric current. This is what the voltage converter does - it will work both from the network and from batteries.
Working diagram of an induction heating boiler
So, the inverter heating boiler has 2 circuits:
- Magnetic. Generates an alternating magnetic field.
- Pipe coil. Heats up the coolant.
When an electric current is applied, the coil generates a magnetic field, which heats the water in the pipe system.
What is beautiful and what is bad inverter boiler
The inverter heating boiler has a couple of positive qualities:
- Since there are no TENOV, the performance characteristics become greater.
- The inertia of heating is small. So, if the system has a centrifugal pump, then the heating rate of the heat carrier will be higher.
- Reduced needs for the chemical characteristics of the heat carrier. After all, TEN, in this case - a winding, does not come into direct contact with water. Due to this, the composition of the heat carrier will be determined only by the characteristics of the heating devices and pipes.
Inverter boiler device
Of the minuses, it should be noted:
- First of all, cost. Compared to tubular heater boilers, inverter boilers will be more expensive.
- Pretty impressive size and weight. To organize a heating system in large rooms, you will need a volumetric heat transfer chamber, thanks to this, a decent number of turns in the coil.
- Power control requires a complex electronic control system.
Despite the presence of these shortcomings, the number of objects heated by boilers that use voltage converters for heating boilers is growing.
Organization of the heating system
Depending on what power, all inverter boilers can be divided into these types:
- Industrial. They have large dimensions, a very complex system for changing the current (performs a voltage converter for a heating boiler), volumetric heat exchangers.
- Home. For this version of the models, rather small dimensions are characteristic, and also the ability to work from the mains and from batteries.
To organize an inverter-type heating system, it is necessary to design it very carefully in advance.
When the boiler does not stop working, the total load in the electrical network of the premises will increase, due to this, wiring will need to be carried out with a large cross section.
An important nuance is the safety of the boiler. And this nuance must be properly guaranteed.So, you will need to install a protective electrical unit that will automatically de-energize the boiler if power surges are observed in the network.
Why you need an inverter
Many people still remember color tube TVs, the weight of which reached 60 kilograms. It was possible to reduce their dimensions and weight thanks to the use of inverters in power supplies. The inverter converted the mains voltage with a frequency of 50 hertz into a high frequency voltage of several tens of kilohertz. This voltage was supplied to a transformer, the distinguishing feature of which was a core made of a special ferromagnetic alloy. The physical properties of the applied ferromagnetic material made it possible to significantly reduce the dimensions and weight of the power transformer. The conversion of mains voltage of 50 hertz to high frequency is used in vortex induction boilers - these are new generation induction boilers for home heating.
Voltage is supplied to them from the inverter, the transformer coil is a winding on the central pipe made of a ferromagnetic alloy, and the secondary short-circuited winding is a pipe and an induction boiler body. This technical solution made it possible to make the boiler compact, reliable and economical. But on the other hand, the use of expensive copper for winding and special alloys for heat exchangers, an automation unit and an inverter made the cost of the product high. Therefore, for any induction boiler, the price will be much higher than for an electric heating element boiler.
High-quality uninterruptibles for gas boilers
Gas and electric boilers, which serve as an important element of the autonomous heating system, are particularly sensitive to voltage drops in the network. With an increase in electricity consumption (in extreme cold), they are especially often automatically turned off, due to which the efficiency of their use is noticeably reduced.
However, buying and using more expensive and powerful voltage inverters for the home as backup power supply for boilers not rational. In addition, for the normal functioning of such a device, you may have to change the wiring.
Therefore, it is more profitable and easier to buy and install an inverter for the boiler. Unlike such powerful household appliances as an electric kettle, a boiler, a fan heater, etc., gas boilers, as a rule, have a low power (up to 600 W). At buying inverters for the boiler it will be enough for you to choose a less powerful and more budgetary device.
If you want to provide long-term backup power, then to boiler inverters experts select an additional set of batteries. According to the average hourly load, they calculate the maximum battery life of the UPS for the boiler and the required battery power.
