Many people encounter the problem of heating the water. This may be frequent interruptions feed water and central heating in multi-storey houses. In addition, the autonomy primarily think the owners of country houses. Recently, hot water electric boiler is a good alternative to gas or solid fuel. Often, this equipment is also installed with other appliances, heating liquid.
basic information
Many argue that the electric boilers can be more economical than other types of plants. To find out you need to analyze indicators such as efficiency. It is considered a major issue in the rationality of energy transformation. In electrical installations for various types of these figures differ from 95 to 98%.
Classification
Electric boilers are divided into three main types:
- TENovye;
- electrode;
- induction.
In addition, there are a number of other differences between them. For example, there are floor or wall-mounted model. They can be connected to 380V or 220V - depending on the size of the room (used for private home or a small apartment). Also, the main indicator is the number of circuits in which there is hot water - one or two.
TENovye
Electric boiler operates based on the process of transformation of current into heat energy by the use of tubular heating elements mounted directly in the tank. Heater raises the temperature of the fluid inside the pipe. She's getting into the heating system heats the room.
For the device to work exactly as desired, provided the control unit. For heating ensures room temperature control. That he sees a decrease of this indicator and informs the need to increase heating. The required pressure is a result of the connection of the pump. By using modern technology, after the room temperature rises to the set level, is turned off. After some time, it stops working, and a pump that moves the coolant.
The main advantage of this type of boilers - there is no contact between the fluid and the heat exchanger. This allows the use of safety devices for automatic shutdown.
The equipment makes it possible to realize a smooth or step regulation.
Like any other device, these have their drawbacks. TENovye compared to other boilers have a limited life. It is not excluded and premature burnout due to improper use. Before purchasing be sure to pay attention to the possibility of repair or replacement.
Also on the tubular heater to quickly form scale. This significantly reduces the lifetime of the device. Be sure to artificially reduce the stiffness of the fluid.
Such hot water boilers are single- and double-circuit units. The latter provide hot water and heating.
In most cases installing hung on the wall, although there are some which are disposed on a flat hard surface.
This species is considered to be the most popular among electric boilers.
electrode
Heating of the heat carrier is carried out by direct passage of current therethrough. In this case, there is no "middleman" in the form of PETN. Electrolysis does not occur, as the anode and the cathode are constantly changing places.
Importantly, in the case of operation without liquid, an electric heating boiler or hot water will not fail. In addition, the scale does not destroy the electrodes - sometimes there is a slight reduction in power.
coolant temperature rises quickly. This increases the pressure with which the water and moved over the network - no need to install the pump. Perfect for the bathroom, because it does not take up much space.
Such water unit has an efficiency of about 96%. In this case, it is durable and reliable in use.
Such a device can not connect through the security element. The only special antifreeze is used as a coolant.
induction
Such units have a structure similar to a transformer, consisting of two circuits. The primary advocates magnet system, and the secondary - the heat exchange device. By alternating field therein allows electricity to heat the coolant.
The main advantages can be called security, as well as interaction with different liquids for heating. As the last option is well suited for the bathroom.
But then there are also disadvantages. The main considered the primary price and the cost of the subsequent operation.
boilers
We should also remember the electric storage unit. In fact they represent TENovye equipment installed in parallel. At the same time it can be designed as a stand for hot water or heating, or for both directions. For the latter, indirect heating systems are used. Such accumulative electric installations allow water to raise the temperature of the coolant for household purposes, intended for heating.
This boiler is ideal for use in suburban homes. It is mainly installed with boilers using any energy source. At the same time outside it lukewarm, because usually these plants have good protection, allows you to save energy in a long time.
Common positive aspects
If we consider, in general, all electric boilers, regardless of type, have a number of advantages:
- ease of implementation;
- there is no need to create a separate space for installation;
- You do not need to think about the purchase, delivery and storage of energy carriers;
- there is no need to output the chimney;
- safety, because there is no possibility of leakage of poisonous substances;
- Environmentally friendly - no harmful emissions.
When installing electric hot-water two-circuit units, connecting all of its functions, the consumer is not will experience any problems with space heating or water supply to the desired temperature for the economic needs.
Saving
Of course, compared with the other, this type of installation for hot water and heating is not the most economical, because the resource is absorbed much. And while energy costs rather big. For example, solid and gas installations are considered to be more economical. But at the same time they definitely need a good set up. Otherwise, the energy costs can be high.
This type of water heating can be a way for the owners of country houses, when the heating season begins, with no other resources, in addition to electricity. These devices are easy to install and operate. They are great for temporary use. But with constant inclusion requires considerable financial costs.
