Electric heating boilers: classification, selection recommendations and overview of manufacturers

Features of the electric boiler device

The main structural elements of an electric heating boiler are a tank and a heating element. The instruments are equipped with control and automatic control systems.

Also, expansion tanks and circulation pumps may be included in the package of various models.

When buying a boiler, you should pay attention to the type of electric heating element. Over time, lime particles settle on the heating elements, which affects the power of the device. Electric boilers have several advantages:

Electric boilers have several advantages:

1. Fire safety. Thanks to automatic control systems and the absence of open flames, the devices are safe. They do not emit toxic substances and products of combustion, they are not capable of exploding.
2. Ease of installation. No chimney or ventilation is required for electrical equipment, which makes installation easier.
3. High efficiency. Regardless of the type of heating device, all electric boilers are highly efficient.
4. Compactness. Electrical appliances, especially mounted ones, take up little space.
5. Nice design. Most modern models are stylistically versatile and look good in the interior.

Electric boilers are almost perfect - easy to operate, safe. Their only serious drawback is the high cost of electricity. Another nuance: residents of regions where there are frequent interruptions in the operation of the power grid, it is better to choose boilers powered by other energy sources, or take care of buying additional heating devices.

Features of the installation of ion boilers

A prerequisite for the installation of ion heating boilers is the presence of a safety valve, a pressure gauge and an automatic air vent. The equipment must be placed in a vertical position (horizontal or at an angle are unacceptable). At the same time, about 1.5 m of supply pipes are not galvanized steel.

The zero terminal is usually located at the bottom of the boiler.A ground wire with a resistance of up to 4 ohms and a cross section of more than 4 mm is connected to it. You should not rely solely on RAM - it is not able to help with leakage currents. The resistance must also comply with the rules of the PUE.

If the heating system is completely new, it is not necessary to prepare the pipes - they must be clean inside. When the boiler crashes into an already operating line, flushing with inhibitors is mandatory. The markets offer a wide range of products for removing deposits, salts and scale. However, each manufacturer of electrode boilers indicates those that he considers the best for his equipment. Their opinion should be followed. Neglecting washing, it will not be possible to establish the exact ohmic resistance.

It is very important to choose heating radiators for the ion boiler. Models with a large internal volume will not work, since more than 10 liters of coolant will be required per 1 kW of power

The boiler will constantly work, wasting part of the electricity in vain. The ideal ratio of boiler power and the total volume of the heating system is 8 liters per 1 kW.

If we talk about materials, it is better to install modern aluminum and bimetallic radiators with minimal inertia. When choosing aluminum models, preference is given to primary type material (not remelted). Compared to the secondary, it contains fewer impurities, reducing the ohmic resistance.

Cast iron radiators are the least compatible with an ion boiler, as they are the most susceptible to pollution. If it is not possible to replace them, experts recommend observing several important conditions:

• The documents must indicate compliance with the European standard
• Mandatory installation of coarse filters and sludge traps
• Once again, the total volume of the coolant is produced and equipment suitable for power is selected

The nuances of choosing the right model

Electricity is an expensive energy resource. If the boiler is chosen incorrectly, you will have to pay huge electricity bills.

Therefore, it makes sense to pay attention to some nuances:

• Device functions. It is necessary to decide what functions the boiler should perform - only heat the house or additionally supply it with hot water.
• Technical indicators of the boiler. Be sure to take into account not only the heated area, but also the degree of its thermal insulation.
• Price. In many ways, the cost of heating appliances depends on power, but that's not all. Additional features can lead to a significant increase in the cost of the model. Therefore, you need to clearly understand whether the budget allows you to overpay for convenience.

Even before you start looking for a boiler, you should find out how powerful it should be.

You can calculate the power, focusing on average indicators: 1 kW of electricity is enough to heat a room of 10 sq.m. with a ceiling height of up to 3 m. It turns out that for heating a small house with an area of ​​​​60 m, a device with a power of 6 kW or more is suitable.

It is advisable to take into account the degree of thermal insulation and buy a boiler with a small margin of power (20%). If the house is poorly insulated, it is better to choose a gas or solid fuel model, since heating with electricity will be too expensive.

The history of the emergence of ion boilers

The first ion heating boilers of flow modification were installed at military facilities for heating submarines and ships of the USSR Navy. The technology was declassified in the 90s, after the collapse of the USSR.

The development of this design of boilers was carried out by the Russian company CJSC "GALAN".In 1994, the first serial production of ion boilers GALAN was released.

For 20 years, the model has been successfully developed, the design characteristics and materials used have changed. The creation of Kros automation made it possible for the device to work with water of any quality, which significantly increased the area of ​​​​use of ion boilers.

"Kros" is configured at the initial start-up, and then it works stably, automatically adjusting to the actual quality of the coolant, which ensures high efficiency of domestic heating boilers.

During operation, manual control is not required, therefore there are no adjustment elements on the panel, only indicators of technical condition.

The boiler is well integrated with external climate control units, with the ability to work in the "Smart Home" system and DSM control.

Indirect heating boiler

Such a unit is a sealed tank with a built-in electric spiral. The heating of water in it is carried out with the circulation of the liquid in a closed circuit and its contact with the heating element. Working from electricity allows you to constantly have a supply of warm water, and an intelligent control system ensures the comfort of using the device. Such equipment is made of stainless steel with a heat-insulating glass-ceramic coating.

A sealed container with a volume of up to 1000 liters is able to provide hot water to a large mansion. Depending on the design and type, the indirect boiler is connected to the gas supply system or to the mains. Such equipment is equipped with an automated control mechanism. In winter, the unit can be used for heating and hot water supply, and in summer only for heating liquids.

Indirect water heater device.

A good solution for residential and technical facilities of a small area is an instantaneous water heater.The average capacity of a 2 kW unit is 12 l/min up to a temperature of 60°C. Such a device is suitable for both private cottages and summer cottages with non-permanent residence. It is used to provide hot water and space heating. Advantages of instantaneous water heater:

• compact dimensions that allow you to place equipment in any free area of ​​​​space;
• low value of heating inertia;
• the ability to adjust the temperature;
• integrated system for automatic shutdown of heating elements in the absence of coolant;
• a variety of models that differ in power and price.

How to choose?

When choosing a storage EWH for 100 liters, the following criteria should be considered:

The power of the heating elements. This is an important parameter that determines the heating time of water and its temperature. Domestic installations have a power in the range of 1-6 kW

It is important to bear in mind that as it increases, the cost of electricity also increases. The optimal value is 1.5-2 kW.

Mains voltage

The devices can be designed for single-phase networks with a voltage of 220 V or three-phase lines with a voltage of 380 V. In the latter case, the power of the heating elements increases, but a special power supply is required.

Tank material
The greatest attention should be paid to the inner coating of the barrel. The durability of the entire unit and the quality of water in the system depend on it.
The most common economy class EWHs have an enamel or glass-ceramic coating. Boilers made of stainless steel are distinguished by high reliability. Premium construction uses high quality titanium plating.

Type of heating element (heater). The main options are wet and dry varieties.Wet heater works directly in water. It costs less, but has reduced durability. Dry heating elements are placed in a special flask, which excludes their contact with liquid, which increases the service life and electrical safety.

Preservation of heat in the tank. It is determined by thermal insulation. Reliable EWHs have a thickness of at least 3 cm. In addition, priority is given to modern materials.

Degree of protection. It determines the electrical safety of the device, and is selected taking into account the humidity in the room. In specially designated and dry rooms, it is sufficient to have a degree of protection of at least IP23. In the bath or bathroom you will need a device not lower than IP44.

Control. It can be electromechanical or electronic. The first option is cheaper and easier to use. Electronic control provides more precise adjustment and convenient maintenance.

In addition to these parameters, you should pay attention to additional options.

An important function is protection against overheating.

Ease of service depends on the power-on indication and the main modes. Modern models may have such additional options as accelerated heating, water freezing protection, the ability to connect to a heating system or “warm floor”, water filtration.

How an electric water heater works

As a rule, such devices are used exclusively for hot water supply. But modern technologies make it possible to use it as an additional thermal circuit for heating the water of the heating system. Before using a water heater to prepare the coolant of heating devices, it is necessary to modernize its make-up scheme:

Create a forced coolant circulation circuit.

It is necessary to tie the heating circuit with the installation of protection and control devices: an expansion tank, an electric circulation pump and shut-off and control valves, a control and protection unit with primary sensors for temperature and pressure of the medium.

The originality of the idea, and its practical implementation, lies in the synchronous operation of the same source: for hot water and heating. For this reason, it is first recommended to select an electric pump of the required electrical power. It must be able to cover all hydraulic losses in the system and evenly distribute heat to the heaters. Experts recommend in systems of simultaneous heating of hot water and heating to provide for the installation of water purification filters at the inlet in front of the boiler.

Storage tank and boiler for heating

The storage tank is, ultimately, completely identical to the classic water heater. The difference lies in the internal coil, which is connected to the heating system.

A professionally organized heat supply system through a heat exchanger implies that this component will perform the function of a thermal accumulator. The liquid medium in the tank receives heat through a serpentine heat exchanger connected to an in-house heating pipe system.

Indirect heating boiler

The best alternative to the option of heating small rooms is the inclusion of an indirect heating boiler in the heat supply scheme. They can be universal, able to operate on different types of energy carriers: gas, flue gases from the combustion of solid fuels and electricity.

Typically, such devices are installed in heat supply circuits to increase the overall efficiency in the form of an additional heating source.The traditional heating boiler is considered the main one. For the effective operation of an indirect heating water heater, it is required to install it before entering the return network water into the boiler unit. In this way, it is possible to achieve an optimal heating system.

Do-it-yourself electric boiler for the heating system

The price of industrial modifications of heating water heaters is very high - from 12,000 to 70,000 rubles. and higher. Therefore, their alternative can be a heater made on their own. For this case, it is allowed to use an arbitrary steel tank, increased strength, with the parameters corresponding to the calculated ones.

To tie the heating circuits of a homemade water heater, you will need the following details:

1. Tank. It would be preferable to place an order with a specialized organization for a device made of non-corrosive steel or assemble it on your own. It is necessary to arrange holes on the body in order to solder the inlet / outlet pipes.
2. Coil heating element, the best choice is copper. This metal has the best heat transfer coefficient and temperature elasticity.
3. Fastening elements for tying heating and hot water systems.
4. Safety automation with primary sensors and protective devices in the form of an air vent and an expansion tank. The kit is purchased in the distribution network according to the parameters of the working tank.
5. Thermal protection of the boiler against loss of thermal energy. To do this, at least 5 cm glass wool / basalt heat insulator is placed in the layer between the tank and the protective casing.

How to choose the right boiler?

The choice of an electric boiler largely depends on what kind of dwelling he will have to work in.

For an apartment

In apartments, low-power single-circuit wall-mounted heaters are usually installed.It makes no sense to buy a dual-circuit model, since at low power it will not be able to supply hot water in sufficient quantities.

Wall mounted water heater

For giving

The quality of power supply in holiday villages is much worse than in cities, so an induction boiler is better suited for such conditions. It makes sense to choose a double-circuit model, since in the country you can get by with a small amount of hot water.

Extending the life of an electric boiler

Corrosion is the interaction of water with metal. The higher the temperature of the heated water, the higher the corrosion intensity, so it is recommended not to raise the water temperature above 600C;

Another destructive factor for electric boilers is the formation of scale. To prevent its formation, it is necessary to install a water softener. The most common, reliable and convenient is the electromagnetic filter.

To provide autonomous heating, it is best to purchase an electric or gas boiler, because this is its direct purpose, which means that the heating efficiency will be much higher. An electric boiler is able to provide a reliable and constant supply of hot water.

Top Producers

If you choose the right manufacturer, then you can significantly improve the durability and quality of your heating system accordingly. Now it's time to talk about which electric boiler company is better to choose so as not to overpay.

To date, this manufacturer is considered the best. Also, if necessary, you can choose Bosch or Dakon. If you want to get cheap products, then you should choose Kospel or Protherm. If you plan to choose industrial models, then you should use electric boilers from RusNit.

7 Process

A steel pipe is used as the basis for the future boiler. A block with electrodes is placed inside this structure, and a sleeve is placed on the opposite side. Its task is to connect the elements with the nozzle.

An insulation layer is installed between the tee and the electrodes, which guarantees thermal protection and maximum tightness. Heat-resistant plastic with a threaded end can be used as an insulating material. A screw is placed on the outside of the installation - a zero terminal and a ground terminal are fixed on it. To increase the reliability of the structure, it is better to connect one or two more bolts.

To give a home-made design a minimal aesthetic appeal, it is enough to apply a simple decorative finish, which will additionally serve as electrical protection. Moreover, the front cover will prevent any unwanted access to the system.

It is safe to say that it is quite possible to make an electrode boiler with your own hands. And if you follow the step-by-step guide, without deviating from the correctness of the actions, then the task will be solved in the shortest possible time.

Without a doubt, modern electrode heating boilers are an ideal solution for arranging heating systems in remote regions. Such installations give out high power and quickly warm up an impressive amount of water. At the same time, they are characterized by small dimensions and do not require expensive maintenance.

If it is necessary to heat rooms with an area of ​​​​500 square meters, you can consider connecting several boilers. Proper planning and choosing the optimal connection scheme is the key to economical and high-quality heating in any home.

Kinds

There are three types of household electric boilers: electrode, induction and heating elements.Before deciding which type of device to choose for heating your home, you need to study the features, advantages and disadvantages of each of them.

Electrode boilers

The principle of operation of devices of this type is as follows: the coolant is heated under the action of an electric current due to ionization, as a result of which heat is generated.

Electrode boilers are used exclusively in gravity heating systems. Only water can act as a heat carrier. They are not used in heating low-temperature systems.

These boilers will last a long time: the electrodes included in their package do not burn out, so there is nothing to break in the devices, even the absence of water in the switched on equipment will prevent them from failing. Ease of installation, ease of maintenance, low cost, small dimensions of equipment, lack of scale are the main advantages of electrode action boilers.

Such a boiler has a variable power and depends on the temperature in the coolant system, which heats up quickly during initial start-up. As a result, the power consumption is low.

The disadvantages of electrode boilers for heating a house include the danger of electric shock passing through the coolant. In equipment of this type, electrolysis of the liquid can occur, this will change its composition over time and affect the thermal conductivity. The release of electrolysis gases leads to airing of the entire structure. In addition, these substances are very toxic, so the coolant must be carefully prepared in terms of electrical conductivity.

In an electrode-type boiler, ordinary antifreeze, antifreeze, and distilled water cannot be used. And a coolant that does not freeze is quite expensive and not available to everyone.

Heating elements

Boilers of this type operate due to the heating element (tubular electric heater) immersed in the coolant, it is heated under the influence of electric current and, accordingly, heats the coolant itself.

The main advantage of this equipment is the possibility of using it in any heating systems and various heat carriers. The heating element does not have an electrical connection with the coolant, therefore, in terms of electric shock, it is completely safe. It has constant power. This boiler does not depend on the temperature and type of coolant. Adjusting its power is quite simple.

The coolant can be antifreeze, antifreeze, water. If one heating element fails, the boiler will still continue to function. This device can be used in a single-circuit scheme to provide hot water to residents of the house.

But as a result of the formation of scale, the efficiency of the system decreases, the heating element burns out. If operated without water, the electric heater will quickly fail, resulting in a fire hazard. Boilers of this type are much more expensive than electrode home heating devices.

Induction electric boilers

Principle of operation induction type appliances consists in heating the core located in a magnetic alternating field, due to which the coolant is heated. To increase the heat transfer area, the equipment is made in the form of a labyrinth having thick walls. Moving along it, the coolant (water or other liquid substance) heats up.

The design of the boiler is very reliable, which allows us to talk about a long service life of the device. In addition, scale does not form in it, which is why it lasts longer.But operation without liquid in the system will disable this device in a few minutes, therefore, a prerequisite for operation is the presence of control of the coolant level and automation to turn off when there is a lack of liquid.

Induction-type boilers take up little space: these are pipe sections from several tens of centimeters to 1 meter long. You can place this design anywhere.

Induction heating devices do not require frequent maintenance: in fact, there is nothing to break there, just like in an electrode device. Radiators and pipes need inspection and repair.
Induction boilers have the same advantages as heating elements. They have high-quality automation and low system inertia (does not waste energy), which allows you to save on electricity. The main disadvantage is the high cost.

Household heaters offered to consumers today have an efficiency of 97%, and each kilowatt spent on their operation turns into 0.97 kW of thermal energy. Therefore, it is not worth saying that any of the types of boilers described above is more economical.

What will help save on heating?

There are several devices that help reduce energy consumption and reduce the cost of heating a house:

• Thermostats. Heating boilers equipped with thermostats do not overheat the premises, but at the same time maintain a predetermined temperature regime.
• Programmers. "Smart" boilers regulate the temperature in the room according to a certain schedule. Although the boiler itself is constantly running, the heating element consumes electricity only 34% of this time. Read more about arranging a heating system in a smart home here.
• Multistage power regulators.Thanks to automatic regulators, it is possible to use energy resources in the most rational way.
• Microprocessors. Devices smoothly regulate the power of boilers, and some devices can even be controlled remotely - from smartphones or other gadgets. Such models are expensive, but worth the money spent.

The presence or absence of a circulation pump significantly affects the energy consumption of an electric boiler.

If it is not included in the model package, it is advisable to purchase it separately and connect it to the heating system.

When buying a boiler for a country house or cottage, you should pay attention to the coolant freezing protection systems

The method of heating water with a water heater

According to the method of increasing the temperature of the energy carrier, the flow device does not differ from the storage boiler. The sealed tank is filled with liquid from a centralized water supply. Electric heating elements increase the temperature to a predetermined level. Units of 2 types are characterized by some loss of thermal energy.

Scheme of water heating device.

In a storage boiler, the temperature of the liquid rises inside a sealed container with an integrated heater. Since the volume of the chamber is small, the process proceeds rapidly and with little heat loss. The design of such units includes:

1. Electric pump.
2. Storage tank.
3. Control mechanism for water supply and heating temperature.
