Electric energy-saving boiler: device and principle of operation
Energy-saving electric boilers for the home have one important design difference from conventional ones. There is no heating element in them. Its role is played by an electrode or an inductor. The liquid in such a device acts as not only a coolant, but also a conductor. Inside the boiler, electric current passes from the electrode to the walls precisely through the water, thereby heating it - this is in the case of an electrode. If its function is performed by an inductor, then the water is heated by means of magnetic waves passing through it.
Advantages and disadvantages of energy-saving electric heating boilers
Such equipment has a lot of advantages.The main ones are:
- Small dimensions, which allows the installation of an electric heating energy-saving boiler 220 V even in small rooms;
- Lack of noise during operation, which allows installation even in small apartments;
- Full automation of the process that does not require periodic maintenance;
- The possibility of a hot water supply device, provided that a double-circuit unit is used;
- Ease of installation. This work can be done by a home master without certain knowledge and skills.
Speaking about the advantages of economical electric boilers for heating a private house, one cannot but mention the disadvantages. Actually, it is only one - the inability to use equipment during a power outage.
Boiler parameters worth paying attention to
In order for such equipment to work effectively, it is worth paying attention to some of the technical parameters that it possesses. The electric boiler should not be too large - its size is determined based on the area of the room where it will be installed. It is also important to determine the number of phases. For an apartment with a 220 V household network, single-phase equipment is needed, but for a private house where 380 V is supplied, it will be more profitable to purchase a three-phase one - this will provide additional savings.
The type of system also plays an important role. If it is closed, then the need for periodic topping coolant disappears. And in itself such a system is more effective. Another parameter is the intensity of exploitation. If it is planned to use the boiler only as a backup heating, then the large capacity of the equipment is useless here.
What types of energy-saving electric boilers can be
Such equipment can be divided both by design features - into electrode and induction, and by the method of installation - by floor or wall. You can also select the number of contours - with one or two. First, let's figure out the installation method.
Floor standing electric energy-saving heating boilers have larger dimensions than wall-mounted ones. Such equipment should be chosen if the area of the premises is large, and there is a place for installation for the electric boiler. Usually a separate room is allocated for such equipment. The wall-mounted version is more compact - it can be installed in any bathroom without sacrificing useful space.
By design features, it can be noted that induction electric boilers are less popular. The reason for this is the impossibility of using it in open heating systems... However, such equipment has a number of undeniable advantages. For example, in an induction boiler, even oil can be used as a heat carrier. And the absence of scale formation plays an important role. But it is worth dwelling on the electrode equipment in more detail.

There are situations when it is not possible to use the gas system, for example, if the gas main does not pass nearby. In this case, it is recommended heating the house with electricity. The most economical way can be selected by analyzing all the options offered. This is what we will do in this review.
Electrode heating boilers and their features
This type is the most common, which is not surprising. In most old houses in the private sector, heating is done in an open way. And what is the point of remodeling the entire system for an induction heater, if you can only install electrode equipment.
Here, electrolysis is used as heating.The boiler itself is connected to "zero", while a "phase" is applied to the electrode in the center (three electrodes at a voltage of 380 V). It turns out a kind of "student" or "army" boiler. Such systems are the safest in comparison with heating elements. Indeed, in the event of a water shutdown, a closed electric heating element (in the event of a failure of the automation) can simply explode. Electrode equipment is free of these risks. The lack of liquid in the boiler entails a break in the contact, which means that the electric boiler will simply stop functioning.
We invite the dear reader to read one of the reviews about the electrode boiler for heating a private house.
Gvoz4D, Russia, Ussuriysk: Basic knowledge of physics at the 8th grade level and the ability to distinguish zero from phase are sufficient for installation and commissioning. First of all, do everything according to the instructions and, indeed, special attention to the coolant, compliance with its parameters. (…) I have been using the Galan electrode boiler from the end of December to the present, and I am absolutely satisfied with it. I anticipate an increased bill for electricity, but it will be rather a consequence of playing with salt in water, since I set up the boiler "manually", that is, without a device measuring the load ... Now we have reached the calculated parameters, and now this coal has surrendered to me, this constant strain to heat the stove for five months a year ...

Number of circuits in water heaters
Single-circuit electric heating boilers make it possible to heat only the coolant. They can heat the house, but with the hot water supply system, in this case, they will have to decide something. Typically, homeowners install a separate water heater to solve this problem. However, it is much easier to fix it in another way.
Double-circuit heating boilers are quite a convenient thing. It is especially pleasing that, in the presence of a second circuit for the device of a hot water supply system, there is no additional power consumption. This happens due to the fact that the water is heated from the heating medium of the heating system. Everything happens as follows. In the tank where the hot water supply is located, there is a coil through which the coolant, heated to a certain temperature, passes. At the same time, he gives up part of his heat to water, heating it. It turns out that if you install a single-circuit electric boiler for heating a house of 100 square meters and compare it with a double-circuit analogue that allows you to connect hot water supply, then there will be no noticeable difference in electricity consumption.
Some nuances of choosing a water heater for heating
When deciding what is the most economical electric boiler to choose for the house, you need to decide with what intensity it is supposed to work. If this is only additional heating, then 2-3 kW of power will be enough. You should also think about the need for a second circuit. If you need hot water in the house, then it will be much more profitable to purchase a double-circuit water heater for heating than to buy a separate one for hot water supply. And in the process of operation, obvious savings will be noticeable.
For many, the most important quality indicator is the brand, but you should not blindly trust what is written on the package. In our time, there is a lot of falsification. But even if all the documents and certificates are in order, there may be an electric boiler next to it on the counter with the same characteristics and not worse quality, but at a lower cost. This happens because of the overpricing "for the brand". The more it is promoted, the higher the cost of the goods will be, which is not always justified by the quality and equipment.
Overview of the most famous manufacturers and prices for electric heating energy-saving boilers
There are quite a few well-known brands of electric boilers in Russia. But today we will try to consider the most famous of them, necessarily domestic production. Of course, it was possible to include foreign brands in the review, but their cost is much higher, which cannot but disappoint.
Domestic brand: electric energy-saving boilers "Galan"
Quite a well-known company that produces high-quality and inexpensive equipment. Of course, there are people who are not enthusiastic about its products, but here you should understand the specifics of using electrode boilers. Knowledgeable people advise adding a little salt to the coolant for more efficient operation.
Very important! You should not fill up salt without certain calculations and knowledge. It is better to seek help from those who understand this. Otherwise, there is a risk that a short circuit will occur and the device will be completely damaged.

"ECO": high-quality water heaters for heating systems
The quality of the products of this manufacturer does not cause any complaints. Buyers who have installed such equipment are quite pleased with the purchase. And here is what the installers say about them.
Vyacheslav: I myself trade in boilers and foam glass. Boilers, as a rule, are taken for backup heating. Simple and reliable design. So far, all customers are happy. Either salted water or a special low-freezing liquid (for summer cottages) is taken as a heat carrier. Alternatively, you can use an electric boiler with a film heater. everything is outrageously easy to mount. When using all sorts of bells and whistles, you can really save on heating (daytime and other modes, switching on through the phone, etc.). With a normally insulated house, the costs are not so great. When installed according to the instructions, no gas is emitted. For small volumes, pumps can be dispensed with. Manufacturers guarantee 15 years of normal operation, after which the electrode must be cleaned

The nuances of installing electric boilers for heating
It is not difficult to install an electric boiler for heating a house. This work is quite doable without the help of professionals with your own hands. You just need to follow the instructions, which must be attached to the technical documentation.
It's important to know! Before starting to connect the electrical equipment, it is necessary to remove the voltage from the supply wire from the input machine. Remember that electric shock can not only harm your health - it can be life-threatening!
The only caveat is that many manufacturers break off the warranty agreement when they install themselves. Their main requirement is the installation of equipment by licensed specialists. If such products are purchased, it is better not to take risks and entrust all the work to professionals.
Where to buy electric energy saving boilers for heating
It all depends on the buyer. You can make a similar purchase in a specialized store, but in this case you should be prepared for the fact that you will have to overpay about 15-20% of the cost, compared to online sellers. But there are also pitfalls here. When purchasing equipment through an online store, you need to be extremely careful so as not to fall for the bait of scammers. We advise you to study the reviews of the seller as carefully as possible and try to collect as much information about him as possible.
Advice! If there are no details on the website page of an Internet seller by which it can be checked in the State Register, this should alert and you should not contact such a seller.
Instead of an afterword
When purchasing equipment for a home heating system, you should not grab the first offer that comes across. Even if it seems that the best can no longer be found. It is worth approaching the choice as carefully and deliberately as possible. Only in this case the electric boiler will work for a long time, giving comfort and warmth to you and your loved ones.
