• The mini-boiler is distinguished by its small dimensions, which will allow you to save precious space in your living space.
• The good news is that they are quite easy to install. You don't have to waste your nerves and time.
• Electrode boilers do no harm at all environment, which is very important when, for example, children live in the house.
• This type of boiler can be installed in various closed heating systems, primarily due to its compactness and versatility. In places where network gas is not provided, an electric mini-boiler is an irreplaceable thing.
• They can connect to already existing systems heating, parallel to 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.

Operating principle 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 settings for the device, is controlled by a magnetic starter. The boiler is equipped with a switch, which, to protect against overloads electrical network, will stop heating in time. There is also a special filter designed to clean the heating system of accumulated debris. Electrode mini-boilers have the same temperature control system as refrigerators, air conditioners and irons. The user sets the number of degrees he needs. Next, the coolant reaches the set temperature. Then the thermostat comes into play, turning off the equipment until it cools down by about eight degrees. After this, the boiler turns on again. And this algorithm occurs cyclically.

Purpose of electric mini-boilers

Each device has its own special purpose. U of this type heating systems - installation of the main source of heating the coolant. But despite this, in Lately they are also used in combined systems heating.

Mini-boilers are intended:

• for heating various types premises (residential, industrial; cottages, warehouses, gas stations, greenhouses, etc.);
• for cooking 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 don’t have to pay for gas (but, frankly, electricity consumption increases significantly);
• does not pollute the environment;
• high efficiency ratio;
• the user can connect the boiler to another heating system;
• the need to build a chimney is eliminated (in private houses where gas is not installed);
• space saving;
• It’s quite easy to install and use;
• automatic temperature control.

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 lamp to contacts A1 and A2;
• should not be used metal pipes And cast iron radiators that have already been used (or are simply old), because then the electrodes will become dirty in the system, which may require cleaning them;
• You should not start the boiler if the coolant temperature is less than fifteen degrees Celsius. Otherwise, the system will take a very long time to warm up.

Service maintenance

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

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

The climate control company Termomir offers a wide range of electric boilers of various capacities. Read the information or call our consultants to choose the desired model boiler

Electric boilers are 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 optimally where there is no main gas or where there are strict requirements for the environmental friendliness of heating devices. Also, an electric boiler is often used as a backup heating option in case problems arise with the main boiler, for example, a gas one.

An 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 with 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 heated floors.

pros:
Compared to boilers using other types of fuel, electric boilers are cheaper, more compact, safe and silent. 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 can be installed in utility rooms or utility rooms, pantries, kitchens, basements, and even living rooms.
Electric boilers are easy to operate and do not create harmful emissions or foreign odors, do not require constant maintenance, expensive cleaning or regular fuel purchases.

Minuses:
Dependence on stable availability of electricity and high demands on quality and reliability electrical wiring. You should also take into account the fairly high cost of electricity. To make an informed decision about purchasing an electric boiler, it is recommended to make a preliminary calculation of electricity costs.

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

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

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

Various remote programmers that can maintain the room temperature according to a user-specified schedule help save energy without sacrificing comfort.

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 electric boiler model, you can contact the consultants of the Termomir 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, boiler and much more), so it is better to entrust the selection of equipment and its complete set to professionals.

Currently our company's product range includes the best electric boilers from European manufacturers, and good inexpensive Russian electric boilers.

A mini-boiler room assembly is a relatively small unit for wall-mounted or floor mounting. Mini boiler houses can operate at the most different sources energy, but for apartments and private houses they most often purchase.

The main difference between a mini-boiler room and a conventional electric boiler is its configuration. Such a device contains all the components necessary for connection to heating circuits and efficient functioning of the system as a whole. Complete heating boilers can have very different configurations, but the basic design elements remain unchanged:

1. A heat exchanger with heaters is the main part of the device in which the coolant is heated. Heating elements are most often used as heating elements, and their configuration and quantity are determined by the model of the mini-boiler house and its power.
2. Expansion tank– a reservoir containing a supply of coolant. The presence allows you to ensure that the pressure in the circuits is maintained at a constant level.

Note! is not included in the heating boiler package. At the same time, the design of most assembled electric boilers provides for the possibility of connecting such devices.

3. Hydrogroup is a device that ensures optimal distribution of coolant in the system. As a rule, the hydraulic group includes one responsible for the circulation of hot water, pressure sensors and safety valves.
4. The control module is an electronics unit that is responsible for adjusting the basic parameters of the boiler. Heating and pumping equipment is usually connected to the control module, which provides flexible system configuration.
5. Circuits and conclusions - in addition to the main elements, the electric heating boiler assembly also includes pipes connecting all components into a single system. The design also includes pipes for connecting the supply and return lines of the heating system.

All described components of the mini-boiler room are located in a single housing. Thanks to this, the device not only turns out to be quite compact, but also looks quite neat. In situations where a heating boiler needs to be installed in a residential area, this becomes a very tangible advantage.

Electric mini-boiler rooms Protherm SKAT

An example of a mini-boiler room assembled with a classic design is electric boilers, presented in the catalog of the Alfatep online store in a fairly wide range.

These devices are characterized by the following features:

Another advantage of the system is the boiler’s freeze protection. Thus, it can be used even in houses that are heated only periodically: with minimal care there is a risk of formation ice jams that violate the integrity of the contours will be excluded.

Advantages of assembled mini boiler houses

Heating problems in a private home, cottage or garage can be easily solved using a device such as an electric boiler.

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

There are electric boilers different sizes: from large ones that require a separate building to compact ones wall models , do not take up much space.

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

Types of electric mini-boilers

Actually an 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.

Installation won't require special permission . Mini electric boilers are divided into two kinds by type of modification.

heating elements new

The water in the system is heated using the heating element of the electric boiler: heating element. Inside it is spiral of tungsten or nichrome wire, which heats up and transfers heat to the environment. The shell is made of steel, titanium or aluminum. Placed between the shell and the spiral dielectric. More often this role is played by quartz sand.

Main elements of the heating element mini-automatic:

• 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 element boilers.

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

Photo 1. New heating element mini electric boiler for a heating system with automatic switch from the manufacturer Galan.

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 breaks down, the device will work.
• Various liquids are used as coolants: water, antifreeze, antifreeze.

Flaws:

• When leaving building a 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 weakly.

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

Ionic

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

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

The ion electric boiler has the following elements:

• frame;
• electrodes;
• housing insulation;
• Control block;
• conductor of heat.

Some electric boiler models are equipped with temperature sensor.

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

Advantages:

• reliability;
• fast heating;
• compactness;
• efficiency.

Photo 2. Ionic small boilers with electronically controlled from the manufacturer Galan, consume a minimum of electricity.

Flaws:

• To fill, you need a special liquid or prepared water.
• Maintaining continuous fluid circulation.

Advantages and disadvantages of small horizontal electric boilers

Electric horizontal electric boilers are an excellent option heating for cottages, dachas, private houses. They have their pros and cons.

• Volatility: It is impossible to install the device away from the electrical network. If there are interruptions in the current supply, then there will be problems, as the equipment will simply fail.
• Expenses: More electricity consumption also leads to increased costs.
• Scale formation: On models with heating elements, water scale forms over time, and the heating element must be replaced.

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

• Power— calculated individually for each type of boiler. The power determines whether the heating of the room will be sufficient.
• Efficiency — for electric boilers the efficiency is high - 95-98%.
• Power adjustment- can be stepped or smooth. In models with independent heating element step 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 noted dimensions, weight electric boiler, efficiency, type of premises which it will heat.
