Electric boilers has recently enjoyed great popularity. This is primarily due to their performance characteristics. They are easy to use and install, safe compact. Therefore, many people want to know how to choose the boiler for heating private houses. After all, in fact, for it to work you need the presence of electricity. Another important factor is the relatively low cost, if we consider the other types of units.
basic information
Electric heating boilers are settings that allow you to use environmental source, non-polluting and is not harmful to humans. Such units are often used together with the indirect heating tanks. Some use them as an additional heat source.
The main components that are necessary to create a good system:
- boiler;
- pump;
- expansion tank;
- safety valve;
- filter;
- Control block.
At that it is necessary to pay attention?
Before you choose an electric boiler for heating, it is necessary to know some of the highlights.
connection
It can be carried out through a network in 220V or 380V. The units, whose power does not exceed 12 kW, connected to any of the two species. But devices consume more power should be connected only to the second embodiment. Therefore, we must first take into account the performance of the local network. Before buying it is necessary to consult with experts.
heating method
There are electric heaters, induction and electrode devices. In the past a special technology is used, which has a number of limitations. Before buying you need to check with all the consultant.
exhibiting power
Before you choose an electric boiler for heating private houses, it is also important to know about the power adjustment. Depending on the structure of the unit, it can be smooth and speed. Electrical devices often have separate heating elements. For exhibiting the desired temperature and the corresponding power consumption, you can simply turn off some of them. Such an adjustment is just called a step. Most often installed inside the three elements. One heats up to half of the maximum power, while the other two only by a quarter. Therefore, there are four options - from 25 to 100%.
If you need a precise and continuous adjustment in the unit structure should be set rheostat. Cheap boilers of small capacity such details do not matter.
Equipment
Electric boiler to the maximum set, which he delivered from the manufacturer, does not require additional components. Therefore, this option is probably the most profitable, though not always cheap. It is important to understand that in the case of buying a low-cost device, will have an additional purchase separate units. Along with it will cost exactly expensive installation costs.
Important! The system will operate poorly without a pump, valve, filter and expansion tank.
installation options
The most popular are considered wall-hung boilers, as they allow to save space. Floor same options are generally designed for large systems which use a lot of fluid.
In addition, before choosing the electric boiler for heating is required to weigh all pros and cons.
dignity
This equipment has a lot of advantages:
- Application. Devices are available at a sufficient capacity - may be selected from Model 2 to 60 kW. Units up to 20 kW are used primarily for the home. Powerful options are more suitable for industrial premises. To ensure the efficiency and reliability of the individual devices are often mounted cascade system.
- Energy efficiency. The main advantage of modern systems is a step power level. This is exactly what makes it possible to save during use.
- Environmentally friendly. Such an effect is provided due to the absence of combustion. Therefore there is no need to create a separate room. In addition, it is not necessary to install a chimney. All this again makes it possible to save space. Particularly suitable for objects of trade.
- Ease of management. Due to the interaction between independent thermostats and programming device is provided in the automatic operation mode. It also allows the electronics select the best option from the energy used and the results obtained.
- Convenience. Quiet operation, simple operation, durability and relatively small price.
disadvantages
Before choosing electric boiler for heating private houses it is also important to take into account some of the shortcomings of the installation of the equipment:
- The cost of electricity. Despite all the positive aspects in the use of electrical equipment, they still can not cover the total price tag on the energy consumed. The use of such aggregates in any case costs hosts more expensive than gas or solid-fuel units. In such cases, many have found a way to connect the tank to excessive heat accumulation. This allows you to significantly reduce their costs.
- dependence on electricity. Choosing this equipment, you should immediately realize that it is 100% tied to the current. In the case of line breakage or any interruption, the device is disabled. A similar situation in any case should not be allowed during the heating season, otherwise it may damage the entire system. In the case of electric boiler as the main, it is sure to have an alternative, by which it will be possible to prevent the cooling of the room and the whole building. this can be a solid fuel boiler for large buildings. A small - fireplace.
- The presence of a suitable wiring. If the building is being constructed, it is possible to provide the wire to be used for different power boilers. And if you have an existing building, sometimes there can be problems with the connection of the device due to the lack of capacity of the local power grid.
The boiler of the production is better to choose?
Units for space heating are foreign and domestic production. The latter provides a simple structure and installed within a relatively cheap components. Most often they have adjustable speed. All this leads to lower cost of imports, as well as reduce the cost of possible repairs.
Foreign devices have a complicated construction and a smooth adjustment. In addition, often provides some additional features for convenient use. One of them can be called a programming operation for some time to come. But they also have an appropriate value.
Electric boiler is a good option that can easily provide the heating of the house. It has many advantages. Although there are some disadvantages. To correctly select the appropriate setting, you need to remember a variety of factors. If they are all taken into account - use this system will be a pleasure.
