Electric boilers represent a fairly simple equipment, the main elements of which are a heat exchanger with heaters, so-called Tanni, and a control unit. They can serve as the main source of heat and optional.

Electric boilers and their advantages

Electrocotels are used for the heating of private houses, offices, shops and other premises of residential and non-residential type, and also have a lot of advantages. First of all, it is absolute safety, environmental friendliness, simplicity and durability in operation, silent operation, compact dimensions, ease of installation and affordable price. However, due to large electricity tariffs, the use of such devices can not be considered cost-effective. Therefore, choosing an electric boiler, it is worth approaching this process with special attention and in advance to calculate the expediency of its application in each case.

Classification of electric boilers

So, to correctly select an electric boiler Consider, first of all, their views.

All modern electrocotes are divided into three groups, depending on the method of heating the coolant:

Tannoye electrocotes

- They represent the devices in which the main heating element is TEN.

Thanks to the contact of the Tan with the coolant (most often it is water) it is heated and, circulating through the system, heat transfer occurs. The main advantages of the tannic boilers are simplicity and compactness of this equipment, modern design, the ability to adjust the power consumption and the use of various coolants in addition to water. At the same time, one of the disadvantages is considered to be the possibility of scale on the heating element, which adversely affects the heat transfer and increases the level of electricity consumed.

Electrode boilers

- These are devices in which the coolant, that is, water is heated due to its own resistance arising at the time of the charge of the charge electrode. They are compact and convenient to use, affordable and safe, and most importantly are not subject to scale formation, as in the previous type. However, such electrocotels work under the condition of normal water circulation. They cannot use other coolants, and the electrodes must be changed regularly.

Induction electric boilers

- This is such a type of boilers, the principle of operation is based on the physical law of electromagnetic induction. Unlike the two previous types of electrocotes in this device there is no heating element as such. The coolant, as not only water can act, heats up due to induction current. Induction boilers have a compact size, are completely safe and do not form scale. At the same time, their price is significantly higher than others.

In addition, wallpapers and outdoor type boilers are also distinguished, one and two-circuit.

Electric boiler selection criteria

The main criteria for the right choice of the electric boiler should be:

Power

The power of the electric boiler should be calculated in view of the fact that 10 m² of heated premises accounts for 1 kW. If this equipment you are going to use not only for heating, but also for uninterrupted hot water, then its power should be several times higher.

Next, it is important to take into account the power of the electrocotel connection. For a low-power device up to 6 kW or an average power boiler up to 12 kW, a single-phase electrical network with a voltage 220W is suitable for installing a double-circuit boiler with a power above 12 kW, it is necessary to take care of the installation of an additional power cable and connecting it to a three-phase 380 kW. In the dependence of the power consumption, the boilers are divided into single-phase and three-phase, and also recently can be found devices that can be connected to any type of power grid.

Equipment

An equally important criterion for choosing an electric boiler is its equipment, which depends on and the cost of such equipment. For example, modern models of heating boilers can have a circulation pump, an expansion tank, a remote programmer and much more.

Do not forget about security. It is better not to save and choose such an electrocotel model, which is equipped with a special system of filters for water purification and preventing the appearance of scale, and also has a function of automatic shutdown with low or vice versa with too high pressure of the coolant, in case of water freezing or overheating of the heating unit. In order to save consumption of electricity consumed, it is worth a preference to electrical boilers with the possibility of changing the modes of operation in the winter and summer period.

Economy

Based on the fact that electric boilers, which have a power of more than 6 kW, have the property consume electricity in large volumes, then they provide the ability to adjust the power depending on the needs at the moment. In addition, in order to save items, it is necessary to use programmers and remote thermostats, which in accordance with the schedule will change the capacity of the work.

Manufacturers and cost

An equally important role when buying an electric boiler plays the choice of a specific manufacturer's company. Today, it is customary today to be the heating devices of such foreign trademarks such as Dakon (Czech Republic), Protherm (Slovakia), Bosch (Germany), the electric goods of domestic production of Russian, as well as some other, for example, Eleko (Slovakia) and others.

Dakon (Czech Republic) offers its customers about 30 diverse boiler models with a maximum capacity of 4-60 kW. Their main difference from other trademarks is the presence of a standard configuration of a multi-stage German circulation pump, as well as water pressure sensors. Dakon products are characterized by excellent quality and is the most affordable in price among all the electrocalls of foreign production on a par with Protherm (Slovakia). They are only cheaper than domestic boilers.
Protherm (Slovakia) is another manufacturer of electrocotes that have a wonderful value for money. Slovak company produces 19 models of five episodes of heating devices that have a power in the range of 9-24 kW. They are distinguished by high functionality, the best efficiency in their class, as well as all models are equipped with an expansion tank and three-speed circulation pump.

The German company Bosch produces electric boilers that meet European quality standards. They are distinguished by the reliability and reliability of work, almost all models are equipped with a circulation pump and an expansion tank. The cost of such equipment is several times higher than its analogues of domestic production, as well as Czech and Slovak boilers.

Domestic electric motors Russian (Rasan) use good demand among buyers thanks to good quality and reliability, as well as available prices. This manufacturer offers single-phase and three-phase boilers with an extreme power of 3-100 kW.
