The heating of a private house is an autonomous heating system, the reliability of which depends primarily on the boiler. The heat carrier heating device can operate on many types of fuel, including electricity.
Heating a private house with an electric boiler eliminates the need for using solid fuel, which must always be loaded into the stove, and in comparison with gas equipment, an electric boiler for heating a private house is safer to operate.
Electric heating system in a private house
Electric heating boilers for a private house are used for many years, but thanks to the development of microprocessor electronics, many current devices can be easily programmed to the desired mode of operation for heating the floor space. Modern electronic boilers are convenient because the heating system can be easily regulated and do not waste electricity at a time when all tenants leave the house, and when using a two-tariff meter, adjust the device to work at night, when the cost of electricity is much lower.
Electric heating boilers
Electric boilers for heating a private house are convenient because their installation is not required to install a chimney to exhaust gases. Electrical installations are virtually silent and do not burn oxygen in the room.
A disadvantage of such systems can be considered only the possibility of electric shock and too high rates for consumed electricity. It is possible to cope with these shortcomings if the equipment is installed taking into account safety regulations, and to save money, as mentioned above, a two-tariff electric meter is purchased.
With the right approach to the use of an electric boiler in a private house, such a system is not inferior to other types of heating installations, and by many criteria far exceeds them.
Electric boiler with a water heater in a private house
Currently, specialized stores are implemented electric heating boilers of various characteristics, which are better for a private house, can be very difficult to understand. When choosing an electric boiler, first of all, pay attention to the following criteria:
type of heating element;
availability of additional functions.
It will depend on the power indicator of the purchased device whether the device will cope with the heating of the living space of the house, and the type of heating element used in the boiler its cost. The cheapest boilers are devices in which heating elements are used to heat the coolant, and the most expensive are induction units. The price of the boiler manufacturer depends on how much it boosts; in addition, the availability of additional functions of electrical equipment will affect the cost indicator.

On our website you can find contacts of construction companies that offer a house insulation service. Directly to communicate with representatives, you can visit the exhibition of houses "Low-rise Country".
The following types of electric boilers are used to heat a private house:
TENOVY - a tubular electric heater is used to heat the heating medium. Such boilers are inexpensive and not too demanding on the quality of the liquid. The main disadvantage of these heaters, is the formation of scale on the heating element, which due to excessive heating can fail.
Induction - the most economical in terms of electricity consumption of the device, but the cost of such a device will be significantly higher compared to the heating boiler.
Electrode - safe to use, but very demanding to the quality of heat carriers type of electric boilers.
Any of the listed units can be used for installation in a private house, but with a large useful heating area, boilers using heating elements are least suitable.
Overview of electric boilers, see the video:
Electric the boiler must fully cope with the task of heating a private house, so the device must be properly selected for power. For the exact calculation it is necessary to calculate the heat loss of the building.With this question, it is better to contact the specialists who will not only establish the places of heat leakage, but also make the necessary calculations of the power of the heating equipment. In general, you should choose a device for 20-30% more powerful than is necessary to ensure the warmth of the whole house.
Such devices are most often used as the main or additional heating of the room. Electric boilers with heating elements can be either wall-mounted or floor-standing. Outdoor units, as a rule, are designed for high power and have large dimensions.
Given the high probability of failure of the heating element, some models are equipped with two heating elements. Such installations are more reliable, and allow you to fully heat the room even if one heating element fails.
Electric heating boiler
An alternating magnetic field is used to heat the heating medium in induction boilers. Under the influence of strong variable magnetic fields, the metal is heated and the heat is transferred to the liquid in the tank. Thus, it is possible to completely isolate the electric heating element from the effects of liquid and salts dissolved in it.
Induction boilers are significantly more expensive than heating devices, but given the high reliability, efficiency and high power of such heating systems, experts recommend making their choice in favor of purchasing boilers of this type.

Some electric boilers perform not only the function of heating the room, but also supplying hot water. Such heating systems have two circuits, one of which passes inside the second. Dual-purpose boilers can save not only energy, but also the useful area of the house, which would be used to house water heating equipment. The main disadvantage of this system is the dependence of the hot water supply on the heating mode of a private house.
It is not difficult to choose an electric double-circuit boiler for heating a private house, but such a heating installation will cost much more than single-circuit models.
Dual-circuit electric boiler
The main difference between double-circuit models from single-circuit units is in size. Dual-circuit boilers should have a sufficient volume of the main tank so that copper tubes of sufficient length could be placed inside it to heat the water in them during the flow of fluid.
In addition, double-circuit models are produced of greater power, because a significant amount of thermal energy can be consumed during frequent intake of hot water.
Single-circuit electric boiler
The electric heating boiler can be installed independently. Depending on the type of unit purchased, the heating unit is mounted on the wall or on the floor. In both cases, the installation is carried out in the following sequence:
marking the location of the boiler;
drilling mounting holes;
installing the boiler on anchor bolts;
connecting the boiler to ground;
connecting the device to the heating system;
connecting the appliance to the power supply;
filling the heating system with coolant and removing air plugs;
starting the boiler.

If all of the above actions were performed correctly, then the electric the boiler will start up and the heating system will start to function normally. During the operation of the boiler it is necessary to monitor the level of coolant in the tank. If it drops to the minimum, then water should be added to the normal value.
In the event of leakage, so that the device does not fail, it is necessary to immediately eliminate the depressurization of the system. Also in the process of operation, electric boilers for the house must be cleaned of contamination and monitor the health of the wiring connected to the device.
Important! Installation and connection of an electric boiler should be done by professionals.
The main disadvantage of using electric boilers for heating a private house is the high probability of a power outage. This usually occurs during natural disasters and power line accidents.Especially often such troubles occur in the winter season, when the heating operation should not be interrupted for a long period of time.
Given the high power consumption of such devices, it is practically unrealistic to provide backup power for the heating system using batteries. The problem can be solved only by connecting powerful generators, which are expensive and consume a large amount of gasoline or diesel fuel.
If you want to connect a powerful heating installation, then, as a rule, such boilers are powered from a three-phase electrical network. Therefore, if in the settlement there is no possibility to connect a voltage of 380 V, then for a large private house heating with electricity will be inaccessible.
An important disadvantage of the use of electricity is the high cost of electricity, which only increases every year.

Heating a house with an electric boiler is a good alternative to using solid fuel. For greater reliability, you can combine these two types of heating, but with a reliable diesel generator, this is not necessary. With such safety net, even the coldest winter and sudden power outages are not terrible.
