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 into alternating current. The inventory manager is responsible for this process. The operation of the inventory can be carried out both from stationary sockets and 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. the 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.

Modern heating systems depend on the uninterrupted operation of the electrical network. Both temporary and long-term interruptions can lead to failure of heating equipment. To prevent this from happening, use inverters for the heating boiler. Also, these devices ensure stable operation of the boiler’s electrical equipment during sudden voltage changes.
Inverters are used to ensure uninterrupted operation of the heating system.
Design and types of devices
Modern inverters are a small and rectangular box that is placed on the floor or hung on the wall. Inside it is a control unit and a standard battery. The unit monitors the availability of electricity in the boiler network and, in special cases, switches to autonomous operation. During periods of power outage, the battery unit supplies power to all electronic components of the boiler.
In this video we will look at the inventory for a gas boiler:
Mostly modern inverters are floor or wall mounted and have a rectangular shape
There are three types of devices:
- Offline- if there is electricity in the network, this device does not take part in the operation of the boiler equipment. As soon as problems with electricity begin, the device will immediately turn on and supply power to the equipment.
- Linear interactive- the boiler equipment is connected directly through an inverter, which in this case is a converter for the heating boiler. It transforms alternating current into direct current; the battery is connected directly between the blocks. In this form, the device normalizes the power supply to the boiler equipment, and in the absence of electricity, it immediately switches to battery operation.
- Online- the device is distinguished by a built-in stabilizer, which makes a backup switch to battery power. The advantage of such a device is that the electrical equipment of the boiler receives a higher quality voltage. True, this device has low performance and high cost.
Some types of devices have the ability to connect external batteries, which greatly extends the life of the inverter. Particularly advantageous are models that have built-in batteries and, at the same time, have the ability to connect an external power source.
Advantages and disadvantages of inverters
The use of these devices is convenient because their operation does not depend on a constant source of constant voltage. It can be powered by a simple car battery or generator.
If the unit does not have a charger, then the owner will have to monitor the performance of the battery.
The advantages of inverters include the following factors:
- smooth operation with all power sources;
- use of batteries of any capacity without restrictions;
- affordable price;
- battery life.
The disadvantages of these units include:
- heavy weight in large heating systems
- difficult adjustment of these devices
Popular models
Currently, there is a fairly large selection of inverters for heating boilers on the Russian market. They can be used in heating systems with any types of heaters.
The most popular models are:
- Energy PN-500- floor-mounted linear-interactive type inverter with a power of 250 W. For uninterrupted operation, an additional battery is required. The unit is small in size and weighs 4.8 kg.
- Energy PN-700N- considered the best wall-mounted unit with a built-in voltage stabilizer. It allows you to ensure uninterrupted operation of the heating system with circulating pumps. This unit can operate at temperatures as low as minus 5°C.
- Energy Pro-1000- an inverter with quite wide functionality. In addition to working in the heating system, it can be used to power other equipment. For example, for the operation of automatic gates and medical electrical equipment. Widely used in both the private sector and industrial production.
- CyberPower SMP 350EI- in addition to the heating system, this unit can provide electricity to any equipment during an emergency shutdown. You can connect low-power household appliances to it. The device has a fairly fast switching time of 4 milliseconds.
You can also note the following brands produced under the Energy brand: Pro-5000, Pro-3400, PN-1500S, etc.
Units for gas boilers
The use of inverters for gas heating is also necessary, as for boilers operating on other types of fuel. The fact is that such a heating system has built-in circulating pumps, the operation of which directly depends on electrical energy. And the control of the heater equipment is completely volatile.
When choosing the right inverter for gas heating First of all, you need to calculate the power connected energy carriers. In this case, for circulation pumps, the starting current value should be taken into account. Therefore, you will have to increase the power of each pump three times and multiply by a factor of 1.2-1.3, and the result will be the total power of the selected unit.
In addition to these data, the battery life of the inverter is taken into account. If a power outage occurs for a long period, then this parameter should be taken into account. At the same time, to provide the inverter with additional power, it is best to use DC generators rather than batteries.
Gasoline inverters can also be used to ensure uninterrupted operation of the electrical equipment of a gas boiler. Currently the most popular of them is the DENZEL GT-950i unit. The advantage of inverter gasoline generators is the absence of a flywheel on the engine, which makes their operation almost silent.
Using electricity to heat rooms in the cold season is a fairly effective and convenient option - after all, this energy carrier is available in almost every house, apartment and even industrial building. However, operating a heating system using electricity alone will cost more than the cost of using any other equipment. It is for this purpose that inverter boilers were created, which have a relatively high efficiency and minimal heat losses with all the advantages of electrical devices.
Operating principle
Models powered by electricity transmit energy using heating elements, which require both a separate area for heating the coolant and protection of the heating element from corrosion. At the same time, the operating principle is based on the phenomenon of electromagnetic induction.
Direct current from the network is converted into alternating current. The resulting magnetic field generates an induced current. And the device that allows all this to happen is precisely an inverter, capable of operating both from the network and from a battery (only for low-power models).
An inverter boiler consists of two main parts: a magnetic circuit and a heat exchanger. The circuit's tasks include creating an alternating magnetic field.
A heat exchanger is needed to transfer energy from the induction current to the coolant, increasing the temperature of the latter to the level necessary for effective heating.
Equipment Features
An inverter boiler, like every type of heating device, has its advantages. Thanks to this, the equipment is quite popular among consumers and is gradually being used more and more often. At the same time, of course, one cannot do without disadvantages, although for such boilers they are not very significant.
The main advantages of such a device are:
- the absence of heating elements, due to which its characteristics are higher than those of electric boilers;
- low heating inertia, which allows you to heat a heated room faster than models with heating elements can do;
- low requirements for water quality. Due to the fact that the heating element, that is, the winding, does not come into contact with water, the chemical composition of the coolant is important only for pipelines and radiators;
- no need for any installation permits, as well as a separate installation room.
Disadvantages of the device
Any technology cannot do without its drawbacks. And for an inverter boiler they are as follows:
- relatively high purchase price and not too wide range;
- large dimensions and weight, which do not make it possible to place inverter devices on the walls, which would save more space;
- a complex equipment control system using electronics (its presence also affects the price).
Heating system installation
Before you begin installing an inverter heating system in a building, you need to determine what equipment will be needed for this. The power of the product is selected depending on the area of the heated premises, taking into account heat loss and a small reserve.
It is approximately believed that 1 kW of heating equipment performance is sufficient to ensure normal microclimatic conditions in an area of 8–10 square meters. m.
For rooms with non-standard heights, for example, production workshops, a kilowatt is enough to heat 2 cubic meters of air.
Features depending on the type of equipment
They select the type of electrical network required to connect it, which can be single- or three-phase. The first is suitable for equipment with a power of up to 10–12 kW, most often used for heating dachas or small private houses. Three-phase is designed for inverter devices with a capacity above 6 kW.
At the same time, boilers with a power of 6 to 12 kW can be connected to a network with a voltage of both 220 and 380 Volts. Such equipment can be used without creating an additional circuit.
In addition, when choosing an inverter boiler for large industrial premises, they prefer industrial equipment with increased dimensions, large heat exchangers and a complex current conversion system. While for home use you will need a household model, relatively compact and cheap.
What to consider during installation?
The use of inverter-type boilers is allowed in both gravity and pressure heating systems. Taking into account the fact that the rate of heating of the coolant is high, it is recommended to install a device in the system for dosing the water supply from the device to the common pipe system. This reduces the need for new heated fluid and increases the efficiency of the device.
Before starting installation, it is worth finding out whether the parameters of the existing electrical wiring will be sufficient for the operation of the new equipment. If necessary, the wires are replaced with others with a larger cross-section. If a three-phase network is required, additional cables are laid separately from the general power supply network. In addition, the equipment requires a special protective unit that automatically turns off the power in the event of sudden changes in voltage in the network.
When arranging inverter heating, you should not forget:
- provide for the installation of a special air release valve in the system;
- about, necessary to compensate for the thermal expansion of the liquid, as well as the circulation pump (unless, of course, the system is free-flow);
- about the location of the boiler at a certain distance from furniture and other things;
- ground the equipment.
It is also recommended to equip the boiler with a remote control device such as an electronic programmer or even a GSM module. With their help, you can provide fairly comfortable heating, for example, of a country house that is not visited daily, but only on weekends.
Eco-friendly homestead: Inverter heating is an excellent solution for heating your home. The cost of purchasing and installing such a design is usually quite high, but in the long run these costs are offset by the good performance of such a system.
The heating system is one of the most important elements of any home, since it is impossible to talk about comfort in a cold house. Heating is especially important in cold climates. The choice of heating system depends on many parameters, but the main ones are efficiency and economy. Heating is often used for six months, and in some regions – for a whole year.
Against the background of many types of heating systems, inverter heating boilers stand out as a bright spot, which differ in a fairly large number of parameters. Inverter heating belongs to the category of devices that use electricity to heat a home.
As a rule, most electric heating structures consume a fairly large amount of energy, so manufacturers are putting every effort into increasing the efficiency of these systems. This article will discuss the principle of operation and features of inverter heating.
Design of an inverter heating boiler
In an inverter boiler, the coolant is heated by converting electrical energy into thermal energy; as a result, the batteries are heated by electricity. The boiler consists of two circuits: magnetic and heat exchange. The magnetic circuit is a coil of conductor attached to a dielectric. An electromagnetic field is created in this circuit, which acts on a metal core installed in the heat exchange circuit. It is the core that transfers the received thermal energy to the coolant. Heating inverters are considered one of the most promising types of heating devices, which can be used both for heating private houses and as a heater for industrial buildings.
Advantages and disadvantages of inverter heating
Inverters, in a broad sense, are devices that convert direct current into alternating current, and their operating principle is based on the phenomenon of electromagnetic induction. How does inverter heating differ from other types of heating systems?
The list of differences is quite impressive:
- The design of inverter boilers has no moving parts or mechanisms, so the wear resistance of such devices is higher. Thus, the service life of inverter boilers is significantly higher than similar devices of other types and is usually at least 10 years.
- Inverter boilers have a fairly simple design, and if necessary, you can assemble it yourself.
- The coolant in inverter boilers heats up much faster than in any other heating system. The reason is simple: inverter devices do not have the usual heat exchanger, so all the thermal energy is used to heat the coolant.
- Almost every inverter boiler can work with any type of coolant, since the working elements of the boiler do not come into direct contact with the coolant. The coolant can only affect the characteristics and performance of the heating system, but the boiler will operate normally.
- Inverter boilers are quite expensive: when compared with conventional household appliances, an inverter boiler will cost at least 2-3 times more.
- Household inverter boilers are heavy, but the dimensions of such devices compensate for this disadvantage. In addition, the successful shape allows you to place such a structure almost anywhere.
- The boiler is adjusted using complex electronic systems that will ensure continuous operation and control of the boiler parameters. Thus, despite the simplicity of assembling the boiler itself, to independently create control elements you will have to study electronics. Installation of electronic systems is mandatory, otherwise the equipment may be damaged and fail.
- Inverter heating devices do not create noise and are fire-safe devices: no fuel is used during operation, which can cause ignition, and there are no moving elements.
- Such systems are environmentally friendly: since no fuel is used, there are no emissions into the environment, because there are no combustion products.
DIY inverter boiler installation
When installing electrical equipment yourself, you need to have some knowledge and skills, but their list is usually small. When all materials and tools are ready, you can begin installing the heating system. Given the possibility of a sudden power outage, it is necessary to take measures to protect the equipment from damage.
An excellent solution to this problem would be to purchase inverter heating batteries, the cost of which is quite high, but in the future they can significantly save on heating the building.
Installing inverter batteries makes it possible to minimize the possible risk of problems occurring during a power outage: the automation will switch the equipment to backup power mode in 10 milliseconds, which will keep the operating temperature at the same level. When the electricity turns on, the reverse procedure will be carried out and the boiler will operate normally. Thus, inverter heating of the house allows minimizing system control.
Autonomous power supplies
Often, for an electric heating system to operate normally, it must periodically switch to an alternative power source, and batteries in this case will be much more convenient than generators. The explanation for this reason is obvious: generators are very dependent on the availability of fuel, which must be purchased, delivered, stored and refueled.
Batteries make it possible to eliminate human actions, since all switching in this case will be carried out automatically. In addition, batteries are much better from an environmental and economic point of view, despite their high cost.
Conclusion
Inverter heating is an excellent solution for heating your home. The cost of purchasing and installing such a design is usually quite high, but in the long run these costs are offset by the good performance of such a system. published

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 expenses for electric heating 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:
- 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.
- 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.
