Electric mini-boilers. Electric heating boilers for private houses

Electric mini-boilers. Electric heating boilers for private houses - Types of electric mini-boilers

The first type is familiar to many. In them, water is heated using heating elements - metal tubes with a high-resistance wire spiral sealed inside. Electric current, passing through the spiral, heats it and, accordingly, the water in the tank is heated. An electric kettle, for example, works on the same principle.

In ion-type boilers, the idea of heating water by electric current is implemented in the absence of the heating element itself. The current conductor is the water itself, in which the electrodes are placed. Ion-type boilers are much more compact than boilers equipped with heating elements, but they require special treatment water. You can, of course, use the usual tap water and water from a well. But this should be done in the most extreme and hopeless case. At the same moment, electric mini boilers equipped with heating elements are practically “indifferent” to the water used and its hardness.

It should also be mentioned that such electric heating installations can be the basis for the heating system of a city apartment or a private country house. This is done thanks to the circulation pump and the built-in expansion tank. They can also be placed in a garage, greenhouse, greenhouse and other utility rooms, observing, of course, all electrical safety requirements.

If such an installation is used as an electric mini boiler room for a summer residence, then you need to be prepared for one unpleasant moment. Unfortunately, the electricity supply in rural areas leaves much to be desired today. Frequent interruptions, banal theft of an electric cable, low current in the network can be a fatal factor for the entire electric heating system in winter period: frozen water will simply break both the boiler and the radiators. In this case, only the prompt draining of water from the entire system will help out.

However, an electric mini-boiler can perform the functions of a parallel (additional) heating system of a private house. These settings can be "embedded" into an existing heating equipment(liquid and solid fuel heaters, AGV, etc.). Combined with modern automated systems control, these parallel systems can work for weeks (subject to a number of conditions) without human intervention.

In conclusion, it should be mentioned that the electric mini boiler room “requires” a special power supply line, which is designed specifically for the passport data of the equipment and is protected by automation from overloads and short circuits. As a rule, it is best to order additional equipment and installation of the system from the organization (company) that implements these electrical installations.

The principle of operation of the electrode boiler

The design of the boiler provides for connection to a closed heating system. And the whole cycle of its work is controlled by built-in automation. It is the automatic controllers that regulate temperature regime system, which can be kept between 20 and 90 degrees.

Also, the magnetic starter, which is built into the boiler controller system, monitors the drop in operating temperature and, if necessary, turns on the heating on its own. After that, it will also turn off the system on its own if it reaches the desired temperature range. In turn, the electrical network will also be protected from possible overloads that occur during the switching on of the boiler, accompanied by increased loads. And in this boiler, the automatic switch will help, it is he who, in the event of critical loads on the network, will turn off the boiler until it is completely stabilized. Also, the boiler system is provided with a coarse filter, which will save the electric boiler device from pollution and further out of service.

Electric boiler miniautomatic new generation

The general principle of operation of the unit is based on the principle of operation of all similar heating elements. In particular, after the boiler heats the system to the set temperature, it will automatically turn it off, and as soon as the system cools down to the minimum allowable level, the electronic system will restart the boiler and start heating the room.

It is worth saying that these units (electric mini-boilers) can be used to heat residential buildings, industrial warehouses, all kinds of industrial premises, country houses, and even greenhouses.
It is also worth noting that these devices can work with heating systems, both with natural circulation of the working fluid, and with forced circulation.
In addition, Electric Boilers can be used to prepare hot water with the participation of indirect heating boilers.
Electric boilers can also be used in the design of thermal curtains, for working with “heat-insulated floors”, for drying wood, in systems with combined water and electricity supply ( wind generators, solar panels, centralized water supply, autonomous well with electric pump).

Consider the main criterion for this system is energy consumption. Low-power heating elements with a low level of energy consumption are installed in this system. This was achieved due to the fact that the boiler does not need to warm up a large amount of coolant in the system. The most powerful heating element that is presented in this system is 1.3 kW, which is designed for heating 20 sq.m. At the first start of the system, for quick heating of the coolant, the heating element is turned on at full power. After the heat carrier warms up, the system automatically switches to maintenance mode and consumes only 30% of its power. The conclusion is this: you can heat 20 square meters of living space for the price of the energy consumption of two incandescent bulbs.

The problems of heating a private house, cottage or garage are easily solved with the help of a device such as an electric boiler.

The equipment is easy to install, has many advantages and helps to create comfortable indoor conditions.

Electric boilers come in different sizes, from large ones that require a separate facility to compact ones. wall models that do not take up much space.

There is also such a modification as a mini-boiler. He is compact module, which the mounted in any closed system heating.

Types of electric mini-boilers

Actually electric boiler installed wherever there is electricity.

It is important that the electric boiler is connected to existing heating systems (gas, solid fuel), reducing the load on them.

Mounting does not require special permission. Mini electric boilers are divided into two kinds by modification type.

heating elements

Heating of system water is carried out by means of a heating element of an electric boiler: TENA. Inside it is helix of tungsten or nichrome wire which heats up and transfers heat environment. The shell is made of steel, titanium or aluminium. Between the shell and the spiral is placed dielectric. More often this role is played by quartz sand.

The main elements of the heating element miniautomatic device:

heating element;
heat exchanger;
insulation;
Control block;
circulation pump.

Important! It is better to use distilled water in the heating system to prevent scale formation. This is the main "disease" of heating elements boilers.

The device has circuit breaker, turning off the device when the desired temperature is reached or in case of overheating.

Advantages:

The power is constant and adjustable.
The temperature of the liquid does not affect the heating element.
If there are several heating elements, then if one device breaks down, the device will work.
Various liquids are used as a heat carrier: water, antifreeze, antifreeze.

Flaws:

In case of failure, the heating element is replaced.
Scale formation on the heating element- the main disadvantage of this device. Because of this, the boiler fails or heats up poorly.

Attention! During operation, the heating element must be covered with water, otherwise it burn out!

Ionic

The principle of operation of new generation ionic electric boilers is different. They do not have a heating element, and the conductor of energy is water or special liquid.

Electrodes are placed here, passing through which the current heats the liquid. Ionic boilers are also called electrode. They heat up quickly, unlike heating elements.

The ion electric boiler has the following elements:

frame;
electrodes;
body insulation;
Control block;
heat conductor.

In some models of electric boiler is installed temperature sensor.

The system has a built-in electronic control: when it cools down, the boiler will turn on by itself, and when the desired temperature is reached, it will turn off. Works even with unstable voltage without shutting down. Compared to a heating element boiler, an ion boiler uses twice smaller electricity.

Advantages:

reliability;
fast heating;
compactness;
economy.

Flaws:

For filling, you need a special liquid or prepared water.
Maintain continuous fluid circulation.

Advantages and disadvantages of small horizontal electric boilers

Electric horizontal electric boilers - a great option heating for cottages, dachas, private houses. They have their pros and cons.

Energy dependence: it is not possible to install the device away from electrical network. If there are interruptions in the supply of current, then there will be problems, since the equipment will simply fail.
Expenses: More electricity consumption also means higher costs.
Scale formation: on models with a heating element, scale from water forms over time, and it is necessary to change the heating element.

In addition to the characteristics discussed above, it is worth paying attention to some features:

Power- calculated individually for each type of boilers. It depends on the power whether the heating of the room will be sufficient.
efficiency — for electric boilers coefficient useful action high - 95-98%.
Power regulation- can be stepped or smooth. In models with an independent heating element, stepwise adjustment is used. Smooth is possible only in devices with a rheostat.
Price- depends on many indicators: type of electric boiler (heating element, ionic), power, manufacturer, additional functions.

Reference! Special attention should also be taken into account dimensions, weight electric boiler, economy, room type which it will heat.

The climatic company "Termomir" offers a wide range of electric boilers of various capacities. Read the information or call our consultants to select the right boiler model.

Electric boilers designed for heating private house, dacha, apartment (including for apartment heating) , various administrative, commercial and industrial facilities ranging from 30 to several thousand square meters. m. Electric heating is optimal where there is no main gas or strict requirements for the environmental friendliness of heating devices. Also, an electric boiler is often used as a backup heating option, in case of problems with the main boiler, for example, gas.

The electric heating boiler consists of a heat exchanger, a block of heating elements, a control unit and control and safety devices. Some electric boilers are equipped circulation pump, expansion tank, safety valve and filter. The coolant heated by electricity circulates through a system of pipes and radiators, providing space heating, as well as heating water in the boiler. An electric double-circuit boiler is used for heating and hot water supply, a single-circuit boiler is used only for heating a house, as well as for underfloor heating.

pros:
Compared to boilers using other fuels, electric boilers are cheaper, more compact, safer and quieter. Connecting electric boilers is much simpler and less expensive than other types of boilers. Due to their compact size and light weight, electric boilers are wall-mounted, do not require a separate boiler room and installation is allowed in utility or utility rooms, pantries, in the kitchen, in the basement, and even in living rooms.
Electric boilers are easy to operate and do not create harmful emissions and odors, do not require constant maintenance, expensive cleaning and regular purchase of fuel.

Minuses:
Dependence on the stable availability of electricity and high demands on quality and reliability electrical wiring. The relatively high cost of electricity should also be taken into account. For an informed decision on the purchase of an electric boiler, it is recommended to make a preliminary calculation of the cost of electricity.

The boiler will be used in the Russian climate from September to April inclusive, i.e. only 8, not 12 months of the year. In autumn and spring, the use of the boiler will be carried out at a minimum, in winter - at full capacity. Thanks to the built-in automation, the operation of the boiler will not be continuous, on average - about 8 hours a day, so the approximate electricity costs for the year can be calculated using the following formula:

240 days X 8 hours a day X boiler capacity X cost of 1 kW of electricity

Electric boilers with a power of up to 12 kW are produced single-phase (power supply 220 V) and three-phase (power supply 380 V), and boilers with a power of more than 12 kW - only three-phase. Most electric boilers with a power of more than 6 kW allow multi-stage power adjustment.

To save energy without sacrificing comfort, various remote programmers that can maintain the temperature in the room according to a user-defined schedule help.

To select an electric boiler, you need to find out the power of the device. Basic calculation - 1 kW of boiler power is enough to heat 10 m2 of a well-insulated room with a ceiling height of up to 3 m.
To select a specific model of an electric boiler, you can contact the consultants of the Thermomir company. Remember that in addition to the boiler itself, it is necessary to purchase other elements of a complete heating and water supply system (radiators, pipes, pumps, thermostats, a boiler and much more), so it is better to entrust the selection of equipment and its complete set to professionals.

At the moment, the assortment of our company includes both the best electric boilers from European manufacturers, and good inexpensive Russian electric boilers.

The mini-boiler is distinguished by its small dimensions, which will allow you to save precious space in your living space.
It can not but rejoice that they are quite easy to mount. You do not have to waste your nerves and time.
Electrode boilers absolutely do not harm the environment, which is very important when, for example, children live in the house.
This type of boilers can be installed to various closed heating systems primarily due to its compactness and versatility. In places where there is no network gas, an electric mini-boiler is an indispensable thing.
They can be connected to already existing heating systems, in parallel with other equipment. To increase the area covered by heat, you can install several copies in one room.
Another advantage of using mini-boilers is their reliability. Water in electrode electric water heaters increases its temperature due to the transfer principle electric current by its molecules.

The principle of operation of electric mini-boilers

There is a certain principle of operation of an electric compact heater. It is inserted into a closed heating system. The user needs to set a certain temperature, and then this equipment will automatically provide it in the room. The adjustable temperature range is as follows: from twenty to ninety degrees Celsius. The temperature sensor, which provides automatic device settings, is controlled by a magnetic starter. The boiler is equipped with a switch, which, in order to protect against overloads of the electrical network, will stop heating in time. There is also a special filter designed to clean the heating system from accumulated debris. Electrode mini-boilers have the same temperature control system as refrigerators, air conditioners and irons. The user sets the desired number of degrees. Then the coolant reaches the set temperature. Then the thermo-regulator comes into operation, which turns off the equipment until it cools down by about eight degrees. After that, the boiler turns on again. And this algorithm happens cyclically.

The purpose of electric mini-boilers

Each device has its own special purpose. For this type of heating systems, installation is the main source of heating of the coolant. But, despite this, they have recently been used in combined heating systems.

Mini boilers are intended for:

for heating various kinds premises (residential, industrial; dachas, warehouses, gas stations, greenhouses, etc.);
for the preparation of hot water using an indirect heating boiler;
for use in heating structures with different ways circulation;
for drying wood;
in combined heat supply structures;
when creating a warm floor (heated).

As you can see, electrode mini-boilers are used quite often and not only at home.

Advantages:

small dimensions, which ensures compactness and versatility;
relatively inexpensive price;
savings, because you do not have to pay for gas (but, frankly, electricity consumption increases greatly);
does not pollute the environment;
high coefficient of efficiency;
the user can connect the boiler to another heating system;
the need to build a chimney is leveled (in private houses where gas is not supplied);
space saving;
it is quite simple to install it, use it too;
automatic thermo-adjustment.

Security measures

To work with an electric mini-boiler, there are certain safety measures, as well as actions that can extend the "life" of your equipment, which must be followed:

there should not be a residual current device in the power supply circuit;
it is forbidden to connect a control light to contacts A1 and A2;
should not be applied metal pipes and cast-iron radiators that have already been used (or simply old), because then the electrodes will be contaminated in the system, which may necessitate their cleaning;
do not start the boiler if the temperature of the coolant is less than fifteen degrees Celsius. Otherwise, the warming up of the system will take a very long time.

Service maintenance

Any technique, unfortunately, tends to wear out. This happens gradually and often imperceptibly for the one who uses it. Therefore, the boiler needs regular checks. It is necessary to carry out Maintenance both before and after the end heating period. As soon as you notice any problems, they should also be fixed immediately. This work is carried out by specially trained masters.

So, electric mini-boilers are distinguished by their compactness and good price. They have a simple principle of operation, and they are not difficult to install. Such equipment can be used in living conditions(when heating a house, for example), and in production processes. Speaking of savings, now there are electric boilers that can consume a minimum of electricity. But, basically, the costs depend on many factors: how insulated the room is, its size, and so on.
