What's happened economical heating? The one that was cheap to purchase equipment and install? Or where the cost of each kilocalorie of heat received is low? As a rule, they mean the second. However, in addition to fuel costs, there is also the cost of equipment maintenance and they often prefer to ignore it. Is it possible to call a heating system economical, in which the specific cost of a unit of thermal energy is unprecedentedly low, but investments in equipment are so high that their payback period exceeds their service life?
Which house has the most economical heating?
Answer: in the house that is insulated the best way. No matter how much effort and money we invest in engineering communications, if the building is poorly insulated, we will still bear unjustifiable costs. heavy expenses for heating. First of all, you should pay attention to the thermal insulation of enclosing structures: external walls, roof, ground floor floor, windows and doors.
The ratio of heat loss through various enclosing structures of an average individual residential building
In current Russian standards In addition to the minimum requirements for thermal insulation, recommended parameters are also specified. The minimum permissible characteristics of enclosing structures are determined by calculation and depend on the climatic conditions of the area. Example: for the climate of the Moscow region, thickness is sufficient outer wall from gas silicate blocks with a density of 500 kg/m2 in 40 cm, but additional external thermal insulation mineral wool at least 8 cm thick.
When insulating a house Special attention pay attention to “cold bridges”: concrete lintels, ends of floor slabs, reinforced belts, window slopes etc.
How much does comfort and personal time cost?
Oddly enough, heating efficiency is partly a relative concept. For example, the owner of a private house lives in a non-gasified but wooded area and has the opportunity to very cheaply procure firewood in the volumes he needs. Fuel costs, even if you have a primitive heating system with an ancient, monstrously power-hungry CFM and registers instead of batteries, will be extremely low. However, the owner will have to work hard to prepare firewood, remember to periodically load it into the firebox, clean the boiler, remove the ash, put up with uneven heating, and the impossibility of precise adjustment. A homeowner can invest in heating modernization, purchase an automatic pellet boiler, and make modern wiring. The consumption of wood fuel in kilograms (tons) will decrease by three times, but the cost of each kilocalorie will increase significantly. In this case, which heating is the most economical - wood or pellet? In terms of unit price, kcal is undoubtedly the first. In terms of quantitative fuel consumption - second. How to evaluate the free time that a home owner will have after switching to pellets? Moreover, more perfect system will create high thermal comfort in the premises, and this is also worth something.
The cheaper way to heat a house
If we discard the possibility of procuring firewood for free and focus on the average prices of Central Russia, the cheapest fuel for many years has been natural gas. It also allows you to fully automate heating, modern gas boilers They only require preventative maintenance once a year. Only electric heating can boast the same properties, but it costs many times more. Even for Western Europe, where the price of gas relative to other types of fuel is much higher than in the Russian Federation, the most economical home heating is gas.
The table reflects the comparative cost of thermal energy for prices in the Moscow region. And if the cost ratio for gas, diesel fuel and electricity in other regions will be similar, then the prices for pellets, firewood and coal may vary greatly depending on local conditions
For gasified areas, there is no alternative to heating with natural gas. If there is no gas pipeline nearby, you need to calculate what is more profitable in the long run. Laying a highway is not a cheap pleasure. The initial investment in equipment also matters.
Cost ratio for the purchase and installation of heating equipment.
As you can see, the initial costs for electric heating, especially direct heating, are the lowest. The level of comfort and safety is maximum, solving problems with electricity supply is easier than with gas, there is no need for a chimney. The main thing that electrical power enough. It is precisely because of low starting costs and ease of installation that buildings built on the “passive house” principle (such are appearing in our area) are increasingly heated with electricity. Based on the totality of initial and operating costs, it turns out that in this case The most economical option is electric heating. Let us repeat that this only applies to modern, well-insulated buildings with low specific heat losses in the absence of a gas pipeline.
Heat from alternative sources
The statement that the most economical heating comes from alternative sources is not true. Pumps that move fluids in geothermal and solar systems consume electricity. And it costs a lot of money. Today, at our prices, heating with gas is still more profitable than installing a heat pump. And there is no need to talk about any serious use of solar collectors in the domestic climate. Today, a more justified solution is to create combined system heating: a heat pump designed for 70% of the required power, and an additional solid fuel (pellet, electric) boiler or fireplace, heating during the period severe frosts missing 30%. Solar collectors, as a rule, used only for heating hot tap water. Let us recall that the cost of “alternative” equipment is still so high that in the conditions of the Russian Federation it often does not even pay for itself during its service life, if we compare its performance with wood heating.
Using the temperature difference between two media, a heat pump draws energy from environment. However, for the constant circulation of the refrigerant and the extraction of energy from it, they work quite powerful pumps consuming electricity
The most economical heating scheme
In water heating systems, in addition to the type of heat generator (boiler), efficiency is also determined by the type of heating devices, heating circuit, type of wiring, and the presence of automation:
- Among heating devices, heated floors are the most economical.
Heated floors are more economical compared to radiators due to a more uniform temperature distribution in the room
- The most economical and comfortable water heating scheme is collector (radiant). It's not cheap, but it's as comfortable as possible. It is followed by a two-pipe one, which can be considered the golden mean. At a moderate cost it is quite effective. A simple one-pipe circuit does not allow adequate regulation of the heat transfer of devices.
Manifold wiring allows you to best balance the hydraulic resistance of the circuits and regulate heat flows
- Automatic control heat flows at all levels (boiler, distributors, devices) also significantly reduces fuel consumption.
Due to the low price of fuel, we are accustomed to squandering thermal energy. And in rich, but very economical Germany, it is hardly possible today to find a radiator without a thermostat
- The most economical heating for a private home is the one that is correctly calculated and competently, professionally designed, installed and configured.
How more complex equipment, the more you can save by setting it up correctly. This is not an easy matter, it requires special knowledge
Economical heating with electricity - myth or reality
The Internet is full of advertisements and articles about “the most innovative, most economical electric heating boiler” and “super electric batteries for economical heating"and similar miracles. All this is nothing more than cunning marketing hype that has nothing to do with reality. In fact, the efficiency of all electric heating devices, regardless of their type, approaches 100%. There is simply nowhere to get the treasured savings. There are only two real ways to reduce the cost of heating with electricity:
- Install a two-tariff meter and heat mainly at night. From 23.00 to 7.00 on weekdays and all weekends, depending on the region, electricity costs 1.4-2.1 times cheaper. By investing in a heat accumulator of sufficient volume, you can stock up on cheap nighttime energy for the day.
- Use heated floors to the maximum: water, with heating from a boiler, and direct heating - cable, film. The savings are relatively small, 4-6%, but in the end it will add up to a tidy sum.
The most economical heating boiler
- Gas. Modern ones consume the least fuel condensing boilers with modulating burners. Savings compared to standard analogues without condensation are 11%, which is quite a lot. However, it should be borne in mind that the advantages of such boilers can only be fully realized in a low-temperature heating system, this will correspond optimal mode boiler operation. Initially, warm floors are low-temperature, but the number of sections in radiators will have to be almost doubled. We can safely say that the most economical heating of a private house is gas, low-temperature, based on a condensing boiler, built according to a radial scheme.
Condensing boilers utilize the potential energy of waste gases, in particular water vapor
- Solid fuel. Pellet and wood pyrolysis boilers consume the least amount of wood fuel.
- Electricity. As already said, “the most economical electric boiler for heating” is a myth; the efficiency is the same for everyone.
- Liquid fuel. The most economical liquid fuel boiler is based on waste machine oil. The only question is where to find a constant source of this almost free type of fuel.
Universal liquid fuel burners are capable of operating on diesel fuel, biofuel, fuel oil (fuel oil) and waste oil.
In conclusion, we emphasize that creating an effective and comfortable heating requires a professional approach. You can try to do everything yourself, but to do this you will have to at least study the basics of heating engineering and hydraulics. If there is no opportunity to devote part of your personal time to these sciences, selection of equipment and installation work, we advise you to entrust the design and installation engineering communications experienced professionals.
Video: economical home heating
When cold weather sets in, the owner of a private house faces the problem of heating the premises. Due to many circumstances, sometimes it is not possible to supply gas, so the question arises of purchasing systems electric heating. It is necessary to choose not only the optimal system that will warm up the entire space, but also one that does not break your pocket every time you have to take readings from the meters. In this plan the best solution is an electric boiler. But questions arise: Which electric boiler is the most economical? How to choose it? There are several types to consider electric heating Houses.
Types and features
We should start with the fact that such boilers have quite a lot of advantages.
- Firstly, it is very convenient and lightweight; you don’t have to spend a lot of time installing it, as it is quite simple.
- Secondly, it won't take up much space. And, plus everything, this is a very inexpensive type of heating.
- Another plus is its high security. If we take into account gas boilers, they are still not so safe; there is a risk of explosion.
- An electric boiler is safe, does not emit odors and does not create noise. It is noteworthy that it has a temperature regulator, that is, another plus - convenience and comfort.
As for efficiency: it depends on the type and model. There are so-called Heating elements new boilers . They work on the principle of a kettle, heating water. They stand out for their fairly low price. There are models that can be installed on the floor, and there are also wall-mounted ones. But it has long been known that scale accumulates on teapots. Heating elements are no exception. Due to this, electricity consumption increases greatly.
Some electric batteries operate on the principle of heating elements. Their heating covers a smaller area, but they are comfortable easy installation And beautiful design, create an excellent warm climate. They heat not the air itself, but the walls and interior items. But it is no longer possible to install a heated floor using such batteries. Such electric batteries have different powers, so for greater efficiency you need to calculate the square footage of the house and, depending on this, choose what power the device should be placed in which room. Plus, it is better to choose liquid-free radiators with the ability to regulate the heating temperature.
There are also automated electric batteries in which you can set daily norm electricity consumption, and they will operate in the specified mode. They are not so convenient to use for a private home.
There are also induction boilers. The principle of operation is comparable to heating elements, but their advantage is that they do not have heating systems. They work according to this principle: An induction coil is located above the boiler system, which heats the water using current. Thus, the boiler becomes universal in that it rarely breaks - simply because there is virtually nothing to break. The advantage is that it is economical. It can work even at low voltage. It also has a high level of security, so it can be installed in any corner of a private home. The downside is its rather high price compared to the previous model. It is also a rather heavy structure, so such a boiler is placed mainly on the floor. And, it is important to note, the principle of the model is based on magnetic inertia, therefore Appliances It's better not to put it close.
The third type is an electrode boiler . Its heating system is built on passing current through the entire coolant. It heats water much faster, which gives it the title of “most economical electric boiler”. It is very compact, which allows you to install it without problems and save space. But this also has its drawbacks. It should be noted that there are many factors that influence energy savings using such a boiler. It is necessary to choose the right radiator for it. There is also a phenomenon called electrolysis, that is, over time, the power decreases, and the system becomes airborne with rather toxic gases. Enough complex installation, so it’s better to call a specialist. Well, in order to regulate the temperature, you will have to install additional equipment.
This type of boiler includes the “scorpion”. Its principle is precisely based on energy efficiency. Having gained the necessary energy, the “scorpion” automatically turns off and comes back into operation when the energy begins to fall. It can have both minimal and high power - this is also its advantage. In addition, the “scorpion” is silent and does not require any technical intervention. But such a copy costs accordingly. If we compare electric batteries with a scorpion-type boiler, then, in terms of savings, there is not much difference. Unless, if you have one boiler, it is much simpler and easier to monitor the temperature and power, and, accordingly, the funds spent on electricity. In addition, Scorpio has high coefficient converting energy into heat.
Owners of private houses also face the problem of cold floors. Electric batteries or boilers heat up the air and interior items, but they are no longer able to cope with the floor.
Warm floors can be water or electric. What is the difference? In efficiency and level of installation complexity. The water floor works by running thin tubes in which it circulates warm water. Electric - due to the passage of electric current. If we compare both types, we can safely conclude that a water heated floor is more economical, but with the condition of operation from gas boiler or central heating. The only difficulty is that such a system is quite expensive to install, but under conditions of long-term use it more than pays for itself.
Electric underfloor heating will be more economical to use in small areas of the house. It is quite easy to install. Not long ago, an infrared floor heating system appeared. It also runs on electricity, but consumes less electricity. This is achieved due to a larger heating area and a small thickness of the screed. In addition, the same electric floor can be more or less economical depending on the finish.
What to choose?
The most economical boiler is an electrode one, but with all installation conditions observed. You can save a lot of money on a Scorpion electric boiler due to its operating mode. In addition, the Scorpion has a power control function, which also has advantages of efficiency. IN small spaces You can get by with electric batteries, so-called convectors. On large area The most economical way to heat a private home is with an electric boiler and water heated floors.
Particularly relevant before the onset of winter cold. Many owners of individual buildings are constantly looking for optimal system. When there is a gas main near the house, the problem with heating the house can be easily solved. But what should those whose buildings are located in remote areas, where there are no communications except electricity? In this case, you can consider installing the most economical electric boiler to heat your home.
Types of electric boilers
The operation of electric heating boilers is to heat the coolant with electric current. Further hot water fills the pipes and, and the house becomes warm. Despite the simplicity of the function performed, there are several types of boilers that have certain operating features. When choosing the most economical boilers for, you should pay attention to the following types:
- Induction – has high power due to the lack of a thermal barrier. The coolant is subjected to double heating due to low level inertia. Boilers of this type are considered eternal and can be easily installed in already existing system.
- Electrode - electricity consumption is 40% less than that of boilers based on heating elements. The water is heated within a few minutes and is lightweight and small in size.
There are other classifications of electric boilers. Devices for are divided into single-phase and three-phase, wall-mounted and floor-mounted.
The simplest small ones economical boilers have a power of 2.5 kW. The electricity consumption of such a device is minimal, but it is suitable for heating small area no more than 25 m2.
Important! Devices with a power of more than 6 kW require a three-phase input in the house.
How to choose an electric boiler?
When choosing an electric boiler, you should proceed primarily from the area of the room that needs to be supplied with heat. The calculation usually used is: 1 kW per 10 m2, therefore, to heat a house with an area of 100 m2, a boiler with a capacity of at least 10 kW is required.
To save energy consumption, you can choose a device with adjustable power. There are devices with automatic and mechanical adjustment. The latest models of electric heating boilers are equipped with microprocessors that control electricity consumption. The cost of such devices is much higher, but smooth power adjustment and maintenance established level energy consumption make it possible to significantly save on costs.
In order to save energy, the boiler should be equipped with a thermostat that can maintain different temperatures in separate rooms of the house.
If you need to not only heat the house, but also install hot water supply, then when choosing a boiler you should pay attention to its equipment. In this case, the kit should also include an expansion tank.
Advantages of electric boilers
Despite the direct dependence of heating using electric boilers on energy resources, these devices have a number of significant advantages:
- High level of security. Gas equipment is at risk of leakage and explosion, and stove heating highlights harmful products combustion. As for electric, it is absolutely harmless.
- Simplicity and speed of installation. Most owners of private houses independently install electrical heating appliances, and even make induction appliances with their own hands.
- There is no need to store fuel, as is the case with solid fuel boilers and. To store firewood, peat or coal, you need to equip a special place, as well as pay for their transportation.
- Almost silent in operation.
- They do not cause damage to the environment.
- Independent choice of temperature in the house.
- There are no requirements for constant care and maintenance.
Among the advantages of an electric boiler, its low cost should be noted in comparison with other types of heating devices.
Disadvantages of electric boilers
Ideal heating system, as well as a way to supply energy for heating, cannot be found, since each case has its own disadvantages. is no exception, since these devices also have their disadvantages:
- If there is a power outage, the equipment will not work, which can lead to pipes freezing. As a rule, the lack of electricity is associated with emergency situations, which the relevant services eliminate in a short time, and during this period there will not be time to cool down to deep freezing, especially if the house has cast iron radiators.
- Electricity costs are the most significant disadvantage. If you use separate electricity metering, then at night, when tariffs are lower, you can set more power, and during the day set it to minimum.
It should be noted that the more expensive an electric boiler, the less electricity it consumes. Therefore, when choosing a suitable device, you should not rely only on price. An expensive boiler will allow you to save on electricity costs in the future.
2018-03-10Of course, if it is possible to connect to gas pipe, the issue of choosing fuel for the home heating system is resolved in favor of the gas model heating device, but to install it you will have to carry out a rather troublesome and large-scale preparatory work: obtain the appropriate permits, organize a ventilation system forced type, and in some cases it will be necessary to install a chimney. In addition, the cost of the equipment is quite high. But an electric boiler for heating a house may well become an alternative, since it is an inexpensive and efficient device that can provide heat as city apartment, and a large country house.
The main advantages of this type of equipment for generating heat in the house include:
⦁efficiency – the efficiency of most models exceeds 99%;
⦁economical, despite high cost electricity, through the use of regulation capabilities, as well as programming the operating modes of the device;
⦁environmentally friendly, since emissions of combustion products are completely eliminated during operation;
⦁availability of energy resources - there is no need to arrange a special storage facility for fuel: it is always available required quantity enters the house via wires;
⦁no need for large-scale installation work, with the exception of supplying a network with a three-phase voltage of 380 V to the house (this requirement applies to boiler models whose power exceeds 6 kW), but if a new house is being built, then permission for this type of power supply to the house should be obtained at the stage zero cycle. Owners of old properties may face the problem of lack of technical feasibility for this purpose, most often, due to the impracticability of increasing the load on existing networks;
⦁compact dimensions;
⦁ease of use, simple and uncomplicated maintenance, the need for which arises infrequently;
⦁long service life, which, however, depends not only on the equipment, but also on the condition electrical networks Houses;
⦁more attractive, compared to gas models, price of equipment with comparable power, which allows you to significantly reduce costs at the initial stage.
But when deciding to use an electric boiler for heating, you should take into account that there are interruptions in the network, sometimes even for a long time, so it should be possible to connect to a backup source, for example, a generator - this will save comfortable conditions in the house and protect the heating system from freezing. Alternatively, if there is alternative heat in the house, to prevent a system breakthrough, you can fill it with a non-freezing coolant, for example, antifreeze.
It is imperative to remember that electric boilers are quite safe installations to operate, but only with proper wiring.
Types of electric boilers
Be sure, before you make a purchase of equipment, you should know that electric boilers used for heating a house come in three types, which is reflected not only in their design features and operating principle, but also in efficiency. Heating of the coolant can occur using heating elements or electrodes, as well as inductively. But regardless of the type of device, structurally it is:
⦁body;
⦁container for heating the coolant;
⦁heating elements;
⦁heat exchanger.
Mandatory element of the majority modern models is the presence of a control unit, in some cases endowed with control functions, including automated ones. Additionally, the electric boiler can be equipped with a circular pump.
Tension electric boilers
The most popular group, also due to the fairly low price and a wide range of models with a power from 2-3 kW to 27 kW, are the so-called shadow devices, which get their name from heating elements - heating coils installed in a metal tubular housing. Thus, the process occurs in two stages: first, the spiral is heated, which transfers the generated heat to the tubes, and the latter ensure exchange with the coolant.
Because of this design feature, the efficiency of shadow appliances is the lowest among all types of electric boilers, since losses occur at two stages of heat transfer. Also, due to the use of low-quality coolant, scale formation on heating elements is possible, which also leads to a decrease in heat transfer. Therefore they are more effective in closed systems, which use specially prepared liquid as a coolant. But the presence of regulatory elements and temperature sensors is quite capable of creating conditions for the economical operation of these boilers.
Electrode boilers
This type of electric boilers differs from shadow boilers in that heating elements it contains special rods: a positively charged cathode and a negative anode. And the principle of operation is based on the use of liquid resistance, therefore it is recommended to use it as a coolant special compounds, the cost of which also slightly increases the cost of heating the house, although it is permissible to fill in water, but it must be specially prepared. Because of this, use them for open systems irrational.
Passed through liquid electricity decomposes molecules into positively and negatively charged particles: the former are attracted to the anode, and the latter, respectively, to the cathode. And as a result of such a chemical reaction, thermal energy is released, which heats the coolant.
Among the disadvantages of such boilers can be considered more high price, but not only. Since as a result of constantly occurring chemical reactions As the rods (electrodes) naturally deteriorate, they need to be changed periodically - on average once every 3-5 years.
But, despite the fact that this is an effective electric boiler for heating, it is not so popular among consumers, largely due to the installation features. So how to use protective devices type RCD is impossible for them; its safety during operation is not complete, even with the mandatory presence of grounding.
These devices are the most compact among electric boilers, since their main element is a dielectric tube in which an induction field is created due to the operation of a steel core placed in a flask. Its surface is an induction coil and serves to transfer thermal energy to the carrier, the loss of which is practically eliminated, which makes it possible to increase the efficiency of the device to almost 100%. Therefore, if it is planned to organize heating of the house using an electric boiler, then this type is the most optimal choice, even though its cost is higher in comparison with shadow models of equal power.
A special feature of the operation of these devices can be considered the absence of scale on the working and heat transfer surfaces, so the efficiency does not decrease. Besides, design features, eliminating the presence of problematic connections - potential places of leaks, guarantee a long service life. Boilers of this type are not picky about the quality of the coolant, so they can be installed in both open and closed systems.
Residents of many private houses and summer cottages, who do not have mains gas nearby, equip their homes with electric boilers for heating. The electric boiler works automatically and all it needs is an uninterrupted power supply. This equipment is safer than solid fuel boilers or oven, as it does not emit smoke and carbon monoxide. Accordingly, such a boiler does not need to be cleaned from ash and soot. At the same time, it is quite cheap and easy to install. You don’t need to look for a special place for it, where there is a hood or chimney. The electric boiler itself is easy to use and silent during operation. It can be placed on the desired temperature regime, and it will work according to the specified parameters
- heating elements new
- electrode
- induction
The main element of the first group of electric boilers is a thermoelectric heater, abbreviated as TEN. Additionally, it has built-in power controllers and temperature sensors.
Principle of operation Such an electric boiler is quite simple: the heat exchanger of the equipment heats the water, which, in turn, transfers heat to the room. The big disadvantage of this type of boiler is that during long-term operation, scale may be deposited on its walls. This, in turn, negatively affects his future work.
There is also another type of boiler - electrode. It contains an electrode as a heat exchanger, which transfers electricity to the coolant. Under the influence of current, water is split into ions, which pass to the electrodes of the corresponding polarity. During this process, the coolant heats up quickly
In this boiler, the electrodes will have to be replaced periodically, as they tend to dissolve
One more modern version electric boilers are induction boilers. They heat the room using an inductive coil that heats the coolant. The disadvantages of this installation are the large size of the boiler and the high price.
Electric boiler selection parameters
The manufacturing technology of an induction boiler is presented in this material:
Economical models of electric boilers with high efficiency
For home heating, most people purchase heating element boilers. With them least hassle and much cheaper than induction or electrode. In addition, the electrode will have to be replaced frequently, which is not very profitable. Among the boilers with electrical element you can highlight the equipment " KOSPEL EKCO", produced in Poland and having an efficiency of more than 99%. This boiler is used for radiator heating. It can also be used in conjunction with a water heater to provide hot water to the home.
Boiler energy savings occur thanks to multi-stage apparatus. For models with power over 50 kW, three-phase installations are provided. There are 2 operating modes available - manual and automatic. The latter is good because it is special software sets required temperature, which changes depending on the time of day. The only drawback common to all boilers of this type is the periodic appearance of scale. If it is not removed, the performance of the device will decrease significantly.
Galan electric boilers are also popular in Russia. Inexpensive and at the same time effective, they have 3 power levels, operate from different electrical networks, both conventional and three-phase, and are light in weight and volume. Users of this boiler describe it as a relatively economical model.
Electrode boilers are less popular among the population. Nevertheless, In terms of their efficiency, they demonstrate high performance. For example, they “eat” 2 times less kilowatts than the same heating element heater, while heating a much larger area. The ability to save energy when using such boilers is achieved thanks to modern technologies. The water in the electrode boiler is heated without additional equipment(for example, a thermal element or an induction coil), so energy is consumed in smaller quantities.
The operation of the electrode boiler is accelerated due to smooth start and modern automation. Among electrode boilers, one of the most popular is “ Geyser» Galan company with power from 9 to 15 kW domestic production, the cost of which is about 12 thousand rubles. Moreover, the price range of such equipment varies from 3.5 to 15 thousand rubles. The line of these products also includes boilers “ Hearth", less powerful than " Geyser" And Vulcan boilers are the most productive, their power reaches 50 kW. All boilers from this manufacturer operate silently and have high performance(from 98%).
These models have all the above advantages of an electrode boiler. The main disadvantages, because of which many are afraid to purchase innovative electrode cats, are risk of electric shock. In addition, an emergency shutdown setting cannot be used for such a unit. If you need to replace the electrode, you will have to constantly seek the help of professionals.
Among induction heating boilers, we can highlight the brand “ SAV» domestically produced by the scientific company INERA. THEIR products have a fairly high price (from 30 thousand to 160 thousand rubles). The cost depends on the power of the purchased boiler (from 2.5 to 100 kW) and the expected heating area. But at the same time it has a number of advantages. The efficiency of the electric boiler of this company is 99 percent. It is equipped with a starting (automatic) relay. The operating principle is the same as conventional induction units.

The undeniable advantages of such a boiler are fast heating, high fire safety, no connectors, due to which leakage often occurs. At the same time, the boiler operates even at low power, which other types of boilers cannot do. Unlike conventional heating elements, scale cannot be deposited on such boilers. And what is very important, the performance of such a boiler does not decrease over time. And their service life reaches 25 years and more.
