The best electric heating boilers for home, Rating 2021

Rating of the most economical and reliable electric heating boilers for a private home. Models are presented with durable heating elements, properly functioning safety automation and effective temperature control. Such boilers do not require complicated installation. There is no need to install a chimney, supply and exhaust ventilation or allocate a room for them. Modern models of heating element modifications have a built-in security system and other necessary elements and components, so to create a simple heating system you do not need bulky boiler piping. Below we will consider the methodology for calculating boiler power by area of the house, calculate energy consumption indicators in seasonal terms and give several ways to save energy.

To choose an electric heating boiler, you need to select the correct power and inspect the electrical wiring. The cross-section of the power cable must correspond to the load. Models up to 3.5 kW are connected directly to the apartment outlet. More powerful electric heating boilers operate through automatic protection devices, which are responsible for controlling the current strength.

The installation of electric boilers with a power of up to 10 kW does not need to be coordinated with Energonadzor. This is done only when connecting a multi-tariff meter in order to save electricity on the price difference between the day and night tariffs. For boilers with a power of more than 6 kW, it is necessary to organize a three-phase connection (380 V).

Advantages and disadvantages

Is it convenient to use this type of boiler for heating? I guess, yes. It is especially good in places where the network voltage is unstable: even when the voltage drops to 180 V, the electrode boiler continues to operate. Its power drops, but it continues to work. What else is such a system convenient for: if you have competent automation and the correct connection of the boiler, the system is autonomous and can maintain the set temperature independently. Another positive point: if for some reason water disappears from the system, the equipment will simply stop working. It won’t burn, won’t deteriorate, but simply won’t work, since water, in this case, is the working medium. Without it, there is no current.

One example of installing an electrode boiler

Now about the disadvantages. From the principle of operation of the electrode boiler, their main drawback emerges: they are demanding on the composition of the water. Not just any water is suitable, but with certain characteristics. When starting the system, it is necessary to prepare the coolant according to the recommendations of the boiler manufacturer. Usually this is a few teaspoons of salt or soda per liter of water in the system. That's all. You can also use special liquids that are produced by the same manufacturers. But this is for those who don’t want to bother at all.

On the other hand, by changing the composition of the water, you can “adjust” the power of the boiler to your needs: in principle, you can make it work with both more and less power relative to what is stated in the passport. It is only necessary to change the chemical composition of the coolant-electrolyte. Here it is important not to overdo it, otherwise you can “modify” the composition until the boiler completely and instantly fails. Therefore, stay within the limits specified by the manufacturer (as usual, “from” and “to” are indicated).

Another unpleasant moment. Even more. The current spreads in the water, and the water circulates in the system. And, in principle, it is possible that if you touch the radiator you will receive a considerable electric shock. This leads to another indispensable condition for safe operation when using electrode boilers for water heating: high-quality and reliable separate grounding is required. It will just help avoid such a situation.

Not the most pleasant moment is the need to periodically clean the system and replace the electrodes - they gradually become thinner and the heating efficiency decreases. In this regard, electrode boilers do not have any advantages over traditional electric boilers with heating elements.

Principle of operation

This equipment differs from other electric boilers in the presence of open electrodes, to which current is supplied from the network (alternating with a frequency of 50 Hz). The electrodes are placed in water of a certain chemical composition. When a potential difference occurs in the electrolyte, which is water, the ions begin to move. Due to the constant change of potentials on the electrodes, the movement of charged particles is chaotic. When the ions move, a large amount of heat is released, which heats the coolant (water in this case).

The operating principle of electrode boilers is based on the ionization of electrolyte (water) molecules and the release of heat as they move towards the electrodes

Reviews about electric heating of a private home and its profitability

The vast majority of reviews about electric heating of a private home are positive in content. Indeed, only those who experience power outages may have complaints, but this problem can be easily solved with the help of a generator.

Practice shows that it is heating devices of this type that have the highest efficiency - up to 98%. This is due to the fact that energy is generated by heating, and combustion products are completely absent. We also cannot fail to mention their cost. Of course, at first glance the amount seems impressive, but after weighing all the pros and cons, it turns out that the price is completely justified.

Thanks to the design of a double-circuit electric heating boiler, you do not have to buy additional consumables. This way you won’t need a chimney at all, because there is simply nothing to discharge into it. In addition, the possibility of self-installation is attractive, which will also allow you to save a little. Light weight and compact size are a significant plus that cannot be ignored. All this makes reviews from owners of private houses with electric heating a kind of advertising, which has been successfully implemented in practice.
