									HEATING SYSTEM WITH ELECTRIC BOILER.

Electric boiler. Usage electric boilers in the heating system is a very good alternative to gas boilers.
Electric boilers can be used as a primary source, as well as an additional source of heating homes and
residential facilities.




Many people think that the use of electric boilers are very expensive. Because the cost of electricity
increases with time. But the maintenance costs of electric boilers are practically equal to expenditure on
maintenance of gas boilers. But for gas boilers need to equip the chimney. The advantages of electric
boilers offset the cost of electrical energy. For ease of operation of electric heating is heating only
competitor in the gas from the pipeline. But it wins at installation time and the amount of spending on
equipment and installation of heating systems.




Also, the use of electric boilers will save you in the construction of communications. On the
construction of buildings with forced ventilation. As well as making records. The use of electric boilers
do not pollute the air from coal dust and the smell of burning gas and diesel fuel. The likelihood of fires
or other emergencies in comparison with the gaseous fuel is much less.
An important parameter in the selection of an electric boiler is its small capacity boilers power. Electric
made - single phase (220V) and three-phase (380 V). Boilers, in which an output exceeding 12 kW
three-phase are. Most electric boilers, power with more than 6 kW - a multi-stage boilers, giving the
opportunity to save energy. They are not included in the total power in the off season - spring and fall.

Electric boilers are classified according to the power to:
 Condos up to 9 kW;
 cottage up to 30 kW;
 Semi 60-70 kW;
 industrial to 200-300 kW.

Electric boilers in terms of technical equipment and complete separation of the following groups:

 Economy - These devices consist of hydro, which has heating elements and simple automation of
electromechanical thermostat. To reduce the size of the boiler, pump placed outside the boiler body.
Electric boilers of this group are designed for operation in the heating system with natural or forced
circulation of coolant. Design of body parts in them simplified.

 Standard - electric boilers are equipped with several degrees of protection, and the circulation pump,
located inside the boiler. These boilers have a beautiful design.

 Premium - an important feature of this class of devices is the availability of electronic security
systems and temperature control, as well as the ability to connect to a centralized system of regulation
of the micro-climate. The device is made from the original design of the cabinet.

Heating electric boilers are usually made wall. Only when a power of 20 kW - floor. Produce electric
boilers and double-circuit single-circuit. The latter are used to provide simultaneous heating and
providing hot water.

Electric boiler inside view. Electric boilers have certain advantages.
Low cost, because they are cheaper, similar in power solid or gas boilers. Simple design and operation,
as electric boilers have compact dimensions and low weight. They are environmentally friendly, do not
emit harmful substances, and they are technically safe. Electric boilers do not require complex care,
and operation is very simple. They are equipped with built-in automatic control systems and
maintaining a certain temperature. Electric boilers produce simple and modern design. Currently,
electric boilers can have from one to four stages of power regulation. Regulated may be in manual and
automatic modes. A degree of equipment of electric boilers these controls, management and security
system manufacturers place a fairly wide range, so the selection of the boiler, pay attention to it.

The disadvantage of electric boilers is dependent on the cost of electricity and the lack of sufficient
capacity in some remote villages. To connect the electrical wiring of the boiler requires enhanced,
while for large power boilers - three phase 380 V. In the case of a large consumer of electricity, the
voltage may drop, leading to an increase in current, and this may affect the serviceability of
automation.

When choosing an electric boiler heating area must be considered. Power of electric boiler is selected
on the basis of about 1 kW to 10 sq.m. well-insulated house, where the ceiling height of 3 m most used
are the double-circuit electric wall boilers 6-15 kW, and among the household - floor electric boilers
20-30 kW, which are used for houses.

Placing Electric boiler. Electric boilers at a cost not very expensive. And because they are more
affordable compared to other boilers for heating. In terms of volume and weight, they are very
compact, and setting them takes a lot of time and is quite simple. Because of their size is not large, so
they are placed mainly on the wall. They can be placed in small rooms. Electric boilers do not require a
professional and easy to care and service they are quite simple. Current models are equipped with built-
in automatic systems of control of the boiler. Electric boilers are simple in appearance and have a
modern design. They are made from environmentally friendly materials, and these boilers do not have a
harmful impact on the environment and people. They are more secure from the boiler, in which there is
an open combustion chamber.

Electric boilers have an efficiency of 100%, and it does not decrease during the whole period of
operation. Unlike gas and boilers and boilers for solid fuels, which will eventually lose their efficiency
up to 50%. The degree of electrical equipment of boiler control and safety elements can be quite broad.
Therefore, when choosing an electric boiler is needed to pay attention. The process of power control of
electric boiler can occur in an automatic or manual modes. Electric heating systems require almost no
maintenance.

In the application of electric boilers in the heating system to heat an average of one cubic meter. area
consumed from 4 to 8 watts of electricity per hour. But if you payment system for electricity, you can
save this money. A very effective and economically beneficial, the combined heating system, such as a
gas boiler and electric boiler, solid fuel boiler and electric boiler. This enables users to reduce the cost
of natural gas within the limited costs of consumption and provide ease of use solid fuel boilers at
different times of the day.

You can save money and in this way: use payment system for electricity and heat storage method is
used when the tariff is low, for example, to heat large quantities of water for domestic hot water. If you
use the counters and switches the room temperature, it is possible at this save up to 30% of electric
energy by maintaining the desired temperature in the house during the day.

The electric boiler is recommended not to put in a house with an area greater than 100 square meters,
because of its power may not be enough. Also, it will consume a lot of electricity, which can not sustain
the network. Therefore, an electric kettle can be placed in such homes, as an emergency so as not to
leave the house with no heat at all, if will not work for some reason the main boiler.

Electric boilers are divided depending on the heating element to: electrode, and (with a tubular electric
heater).

Electric boilers.

How it works tankless electric boilers is to transfer heat from a tubular heater (heating element) to the
coolant - antifreeze and water. The advantage of such boilers is that their fuel elements are not in
contact with the coolant. Power of electric boilers does not depend on the type and temperature of the
coolant. Therefore, these boilers used stepwise or gradual adjustment that minimizes the voltage drops
when you turn on or turn off electric boilers.
As a coolant in these boilers is used ordinary water or antifreeze with no special preparation on the
electrical conductivity. Depending on the model of an electric boiler, the kit may include the following
controls: the boiler thermostat, which regulates and maintains the temperature of the coolant. Safety
thermostat that protects the boiler in an emergency (in case of overheating the coolant), level sensor
and the coolant pressure sensor that turns off the boiler at least reduce the level of the coolant from the
norm. Freezing temperature sensor, which includes the boiler temperature falls below 5-7 ° C and a
pressure relief valve.

For electric boilers can be connected to room thermostat or street, or as a programmer. The thermostat
keeps the temperature in a room. Street boiler thermostat sends information about the temperature
outside the room. The programmer specifies the desired schedule for the boiler. Regulators, working,
depending on the ambient temperature, provide the best comfort temperature control inside the room
with changeable weather conditions.

Electrode electric boilers.

The boilers of the electrode type has a different operating principle: heating the coolant ions are
moving between the electrodes of the boiler. Thus, due to the ionization process fluid, is what makes
the form of positive and negative charged ions. Subsequently, the ions are attracted to one another,
producing heat. These electrode boilers as coolant, mainly use water. For efficient water heater, you
must first prepare that it provides good ionization. But such treatment of water precludes its use in
combined heating systems.

Electrode Boiler is a vessel with electrodes placed in it. The action of the electrode boiler is similar to
water heater. And the characteristic feature of these electric boiler is a very high efficiency - about 96-
98% and an automatic setting for the given parameters of the carrier temperature. When a short circuit,
or leak coolant temperature exceeds a given electrode boilers may themselves disconnected from the
power source.

The heating system water from the electrode boiler is not instantly and consistently. When heated, the
water decreases its resistance, which allows better heat the entire system. Given the volume of your
heating system, you can configure the desired heating temperature of the coolant.
