Selection Guide
Why do people choose these devices? Obviously, it's all about the advantages over gas and wood counterparts.
Advantages of an electric heating system:
- There is no need to install a chimney to remove combustion products, to connect additional ventilation. Accordingly, there are no restrictions on installation and coordination with housing and communal services.
- Ease of control and programming modes. Devices for heating allow you to set the required temperature of the coolant or air on an external sensor.
- Opportunity to use a differentiated tariff scale. That is, during the day the cost of electricity is more expensive, at night, when the peak of consumption passes, it is cheaper by 40-60%. If thermal accumulators are purchased as a set for the boiler, it will save money by storing heat at night and spending it during the day.
- Safety. The risk of system boiling and explosion is reduced to zero.
Heating a house with an electric boiler has the following disadvantages:
- High cost of electricity.
- Constant power surges disable automation. As a result, rapid defrosting and damage to the entire heating structure.
We list the main parameters and technical characteristics of boilers for heating systems, on which the choice depends:
- Manufacturer. It is better to consider products of famous brands. Concerns have an extensive network of service centers that will provide fast and high-quality repairs.
- Power. Before you go to the store, do not forget to correctly calculate it in accordance with the level of heat loss at home.
- Efficiency - not less than 95%. Electricity is the most expensive fuel, so performance must be maximized.
- Security group. Mandatory: limiting the temperature of the thermal carrier (up to +85 ºC), protection against overheating, dry running, pressure sensors and others.
- The number of contours. Single-circuit boilers should be used strictly for their intended purpose, and for hot water supply, purchase separate storage boilers or indirect heating.
- Optional equipment. A heat accumulator, a stabilizer must be included in the piping of a high-power boiler, and if electricity is often cut off in the area, then generators running on diesel or gasoline fuel. The risk of failure of the heating system is reduced to zero.
To paraphrase well-known authors, we can say that electric boilers are not a luxury, but a means of heating in the harsh Russian winter.
Heating boilers
All these requirements are met by the products of the Czech manufacturer Protherm. The range of its boilers is made in the range from 6 to 36 kW. It is noteworthy that models with a power of 6 and 9 kW require connection not only to 380 V, but also to 220 V. Another foreign brand that is actively promoted in the domestic market is the Polish Kospel. This manufacturer starts with devices with a power of 2 kW, but does not imply an expansion tank in its case. Each electric boiler is energy-saving due to the features of the control unit. Automatic mode provides smooth power modulation with a uniform load on the series circuit of heating elements. It is also envisaged to connect weekly programmers that control temperature amplitudes according to a predetermined scheme without involving a person. The unit has outputs to sensors that react promptly to weather changes and issue appropriate commands to increase or decrease electrical energy consumption.
Induction electric boilers
The induction apparatus is the most economical electric boiler, just as the energy of exhaust gases is used in a condensing gas boiler, the induction boiler uses double heating of the coolant (read: “How to choose the most economical electric heating boiler: let's figure it out“).It is also noteworthy that the generated electromagnetic induction does not allow the formation of scale on the parts of the boiler, thereby maintaining the constancy of its performance and increasing the service life.
It is important that boilers with an induction heating circuit can be used in old heating circuits with a large amount of coolant, and low inertia almost halves the time for heating the coolant when compared with the operation of heating units
Summing up the conversation about electric boilers, it should be noted that their use is accompanied by the following positive factors:
- they meet the requirements of environmentalists to save the environment;
- during installation there are no difficulties;
- high safety performance in operation;
- the operation of the boilers is not accompanied by extraneous noise and odors;
- ease of operation and programming;
- savings on the design of units and special equipment (installation of chimneys, installation of coaxial channels).
Unique energy-saving mini-automatic electric boiler
CHEAPER GAS 2 TIMES!
Advantages of heating equipment:
• High thermal efficiency - 98% • Environmental safety • Durability - up to 30 years • Automatic operation • Low noise level • Super compact overall dimensions • Work in any water heating systems • Possibility to create mini-boilers using several modules in parallel • Cheaper than gas, liquid and solid fuel• Warranty — 10 years (s/h — free of charge)
The mini automatic electric boiler was developed on the basis of energy-saving technologies of the Russian military industry for heating houses, summer cottages, shops, kindergartens, garages and households. complexes. Works in automatic mode on/off. 7 hours a day. Smooth adjustment of heating. Has no analogues.
This environmentally friendly, self-contained, super compact and reliable equipment is suitable for any water heating systems and can be installed in parallel with existing ones. The heating module uses a special alloy heating electrode, which, with low power consumption, provides maximum heating of the coolant in the heating system, so heating the premises will cost you less than gas, coal, liquid or solid fuel. Works from 220/380 V.
The power is regulated by an automatic thermostat. The electric modules operate automatically at an outside temperature of -25 -30 degrees with normal thermal insulation of the walls for 1/3 hour (7-8 hours a day). The operation of the electric heating module is based on a new process of converting electrical energy into thermal energy. In the chamber of the electric module, the current flows through the coolant, water, thereby loosening the molecular lattice of water, due to this, rapid heating and energy savings occur.

Parameters of the electric boiler and its connection
The electric boiler of modern design has many parameters, but the most important parameter when choosing is the power of the boiler. It is selected according to your parameters:
- heated area;
- wall material;
- quality and availability of thermal insulation.
Mains voltage
We have two types of electric boilers for heating a house with a power supply of 380 and 220 volts. Smaller boilers are usually rated at 220 volts (single-phase connection), while larger boilers, about 12 kW and above, are rated at 380 volts (three-phase connection). Depending on where the boiler is located, it is divided into types:
Most of the new models of electric boilers are aesthetic, compact and environmentally friendly, so they do not need to be allocated for installation and operation of a separate room.
Installing an electric boiler in the house is not a difficult undertaking. It is easily portable, if necessary, it is easy to dismantle and rearrange it to another place, since these boilers are quite light, compact and mobile.
Installation of an electric boiler
It is necessary to mount a wall-mounted heating electric boiler using anchor bolts or dowels.
Accordingly, the floor electric boiler must be mounted on the floor and on a special stand. Having mounted the boiler on site, it is necessary to connect it to the heating system using adapters and couplings, observing the tightness. Before connecting to the heating system, it is necessary to shut off the water with a ball valve or other shut-off valves.
After you have connected the electric boiler to the heating system, you need to start connecting the electrical wiring. It is mandatory to install an RCD and an automatic switch of the required ratings in order to protect the boiler from possible short circuits and leakage of power to the ground.
Draw your attention to! Like any electrical installation, the electric boiler must be grounded. For your safety
The cross-sections of the wires connected to the electric boiler must comply with the manufacturer's recommendations and withstand the electrical power consumed. After connecting the boiler to the power supply, water is drawn into the system and its operation is tested.
