Installation of a heating boiler is an important stage in home improvement. If the equipment is selected correctly, then, regardless of the weather conditions in the rooms, a comfortable temperature regime will be maintained.
Often in private homes put electric heating boilers. The devices are safe, easy to operate, and their performance depends on the choice of model.
In this material, we will understand the features of the operation of these devices, denote the criteria for choosing heating equipment, and announce the TOP-12 of the best manufacturers according to users.
Features of the electric boiler device
The main structural elements of an electric heating boiler are a tank and a heating element. Devices are equipped with control and automatic control systems.
Also, expansion tanks and circulation pumps can 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, calcareous particles settle on the heating elements, which affects the power of the device
Electric boilers have several advantages:
- Fire safety. Thanks to automatic control systems and the absence of open fire, the devices are safe. They do not emit toxic substances and products of combustion, are not able to explode.
- Convenience of installation. Neither a chimney nor ventilation is required for electrical equipment, which facilitates installation.
- High efficiency. Regardless of the type of heating device, all electric boilers are highly efficient.
- Compactness. Electrical appliances, especially mounted ones, take up little space.
- 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 caveat: residents of regions where there are frequent power outages, it is better to choose boilers that work from other sources of energy, or take care of buying additional heating appliances.
Classification criteria for heating appliances
There is a huge advantage in the variety of electric boilers: you can find a model that is ideally suited for specific operating conditions. At the same time, in order not to make a mistake, the buyer has to understand the nuances.
Electric heating equipment is classified according to several criteria, the main of which are:
- type of heating medium: heating elements, electrode, induction;
- location method: mounted (wall), floor;
- design: single, double-circuit.
Heating electric boilers can differ in other parameters. For example, some manufacturers produce not only single-phase models (220 V), but also three-phase (380 V).
There are also combined boilers in which, in addition to electricity, other energy sources (firewood or gas) can be used.

The design feature of the electrode boiler is the presence of an electrode, which is not a heater, but at the same time performs its functions. The heating medium is heated by transferring electricity to the water. As a result, the temperature of the coolant increases due to increased resistance
By their principle of operation, these boilers resemble electric kettles and boilers: the coolant is heated by the heater and enters the heating system. The only significant difference is that the water warms up in flow mode, and does not accumulate in the tank
Induction electric boilers have a significant advantage over other types of models: their design lacks both heating elements, which are gradually covered with limescale, and electrodes, which dissolve over time. Devices work due to high-frequency currents, due to which they are characterized by high efficiency
Such models are designed exclusively for the heating system and are not suitable for the organization of hot water supply. Single-circuit models of trusted brands do an excellent job of their function, while being simple to operate and rarely require repair. They are reliable and durable.
The main advantage of double-circuit electric boilers is multifunctionality. Models are designed for connection to two systems - heating and domestic hot water. By purchasing one electrical appliance, the owner provides his house with heat and hot water. This is a rational and economically viable solution.
Wall mounted models are ideal for small spaces. They are compact, do not take up space on the floor, so you can rationally use the space and conveniently carry out cleaning. An additional plus - stylistically neutral design
The main disadvantages of floor models are the large size and placement on the floor, and the advantage is power. These electric boilers are perfect for heating large houses, especially if it is possible to equip a separate boiler room
Owners of combined heating boilers are given the choice and can use the energy source that is more available in a given time period. The most popular models are on electricity and natural gas.

Heating and electrode boilers are time-tested, reliable and will suit those home owners who are trying to find a model of decent quality at an affordable price.
Since the electrodes are sensitive to the composition of the coolant, it is necessary to monitor the quality of water in the heating system. If the new boiler is connected to the old system, it is thoroughly washed, removing all impurities and impurities
Induction devices are more suitable for people who appreciate high-performance equipment and cutting-edge design. Their advantage is the freedom to choose a coolant: boilers can be connected to heating systems with non-freezing liquid.
Heating boilers are easy to install and usually have power control systems, but due to the formation of scale on the heating elements, their heat transfer gradually decreases, and the energy consumption increases
Choosing between wall and floor boilers, you should decide on the space on which you can place the device.
Practice shows that floor-mounted electric boilers are more reliable than wall-mounted ones. They break less often and serve longer. If it is possible to allocate space for a floor model, then this will be the best solution.
If you need a powerful boiler, and the room is spacious, you should give preference to the floor model, and for houses with an area of up to 100 sq.m. You can choose a wall.
The principles of operation of induction and heating devices differ significantly, although this slightly affects the efficiency. The main difference is in the amount of initial investments, but over time, the costs of servicing boilers are equalized, because due to the lack of heating elements, induction models require less repair
Any type of electric water-heating boiler has advantages and limitations in use, therefore, appliances should be selected based on their own needs, priorities and features of the operation of heating equipment.
The nuances of choosing the right model
Electricity is an expensive energy resource. If the boiler is not selected correctly, you will have to pay huge bills for electricity.
Therefore, it makes sense to pay attention to some nuances:
- Functions instrument. It is necessary to determine what functions the boiler should perform - only heat the house or additionally supply it with hot water.
- Technical indicators boiler. Necessarily 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 is 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.
Before starting the search for the boiler, you should find out how powerful it should be.
You can calculate the power, focusing on averaged indicators: 1 kW of electricity is enough to heat a room of 10 square meters. 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 capacity of 6 kW is suitable.
When buying an electric boiler, energy consumption is of fundamental importance. It’s better to overpay for a more expensive model, but save on its operation
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 cost too much.
What will help to 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 room, but at the same time maintain the specified temperature regime.
- Programmers. Smart boilers regulate the room temperature according to a specific schedule. Although the boiler itself operates continuously, the heating element consumes electricity only 34% of this time. Read more about arranging a heating system in a smart home here.
- Multi-stage power controllers. Thanks to automatic regulators, it is possible to use energy resources extremely rationally.
- 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.
The energy consumption of an electric boiler is noticeably affected by the presence or absence of a circulation pump.
If it is not included in the model, it is advisable to purchase it separately and connect to the heating system.
If it is likely that in the cold season the house will be left for a while, it is better to choose a model with a coolant frost protection system
When buying a boiler for a country house or cottage, you should pay attention to the anti-freeze protection systems of the coolant.
