Electric double-circuit heating boilers and their features

Despite the fact that gas is the most optimal fuel for heating systems, in our country far from all the villages are gasified, especially the country houses. Therefore, double-circuit electric heating boilers, which provide not only heating, but also the supply of warm water, are in certain demand among consumers. In this article we will take a closer look at the features and types of these devices.

Features of electric boilers

Merits

First of all, we will consider the advantages of double-circuit boilers, thanks to which they enjoy a certain popularity:

• Easy installation - Unlike gas installations, electric boilers do not require leading gas pipes to the house, which not only simplifies the installation of the heating system, but also makes it cheaper.
• Environmental friendliness and noiselessness - during operation, these devices do not emit combustion products, and also work completely silently. Therefore, there is no need to make a hole in the wall and install the chimney.
• Fire safety and ease of operation - double-circuit electric heating boilers can operate in automatic mode, moreover, they are more fire safe, since there is no open fire during operation.
• Small dimensions and low weight, what allows to save the place in the house and not to allocate the separate room for installation of a copper.
• Low price - electric devices are cheaper than gas.

For these reasons, electric boilers are sometimes used not only in country houses, but also in city apartments.

disadvantages

Of course, this device also has disadvantages, and they consist in the following points:

• Power outages - often occur due to natural disasters, as well as the work of the relevant services;
• The high cost of electricity - is the main drawback of electric boilers.
• The need for powerful wiring - if the wires in the house have a small cross-section, then they will have to be replaced, otherwise the device can not be used at full capacity.

It follows that before choosing the electric boiler, it is necessary to weigh the pros and cons. It makes sense to install it only if it is not possible to use a heater that operates on a cheaper type of fuel.

Device and species

Electric double-circuit heating boiler has a fairly simple device and consists of only two main elements:

• Heat exchanger with heating elements;
• Control unit.

For domestic needs, these devices are made in two variations:

• Biphasic;
• Three phase.

If the power exceeds 12 kW, then the device is necessarily three-phase. Less powerful devices make two-phase. In addition, all boilers differ in the method of installation in the room, they are:

It should also be noted that in addition to the double-circuit boilers, which work both for space heating and for the hot water supply system, there are also single-circuit boilers. In fact, this is a simplified version of the devices that heat the water only for the needs of heating.

By the method of heating the devices are divided into several types:

Tip! After you install a double-circuit electric boiler for heating, the question arises - how to reduce energy costs and make heating cheaper? Provide some savings can special devices - programmers. Their use will reduce energy consumption by up to thirty percent without loss of heating quality.

Application area

Instructions for use of electric heating boilers allows their use for heating:

• Apartments;
• Country houses and country houses;
• Offices;
• Production facilities;
• Hospitals and schools;
• Warehouses, etc.

Often they are used for traditional heating systems and floor heating devices.

Tip! The electric boiler can be used not only as the main device of heating, but also as a backup, for example, it can be an addition to the device running on solid fuel.

Connection Features

Connecting an electric boiler to the heating system is no different from installing gas or solid fuel appliances. The only thing, as mentioned above, the device does not require a chimney.

As a rule, the device is connected to the finished heating system, the device of which depends on the characteristics of housing, such as:

• Square;
• Number of floors;
• Number of rooms, etc.

After installation of the system, the boiler is connected to the pipes with a threaded joint. At the same time it is necessary to properly connect the outlet and the inlet pipe with your own hands. In addition, double-circuit boilers have an additional two pipes for the inlet of cold water and the outlet of hot.

To turn on the device, simply connect it to electricity. After installation, you should check the operation of the heating system and hot water. If the test is successful, then you only need to set certain modes of operation of the device, after which it will work automatically.

Tip! Currently, electric boilers from both foreign and domestic manufacturers are on the market. Moreover, the quality of the latter is in no way inferior to imported products, despite the fact that their cost is much lower.

Here, in fact, all the main features of electric double-circuit boilers.

Conclusion

The use of electric double-circuit boilers is an excellent way to ensure comfortable living conditions in cases where the housing is not connected to the gas pipeline. These devices are not only effective, but also easy to use, although they are not without some drawbacks.
