Component parts for electric boiler EOU
To start a heating system with an electric boiler, you do not need to purchase any of our branded components. For electricians to control the boiler, you can either purchase from us a ready-made unit for controlling the boiler, or also from us or yourself (in any specialized electrician store), you can purchase a circuit breaker and a magnetic starter (contactor), and install them in your box with an electrician (the connection diagram is indicated in the boiler passport). You can buy all this on our website at the following link: Electric boiler control unit.
The electric boiler EOU, the price of which is low, is sold together with a thermostat, so you do not need to buy it in addition.
In a heating system with an EOU electric boiler, in addition to distilled, melt or rain water, an anti-freezing liquid can be used for heating for electrode boilers as a heat carrier. It is enough to change the liquid in the heating system once every 5-6 years. You can also purchase non-freezing liquid for heating from us at the following link: Heat carrier for electrode boilers.
Electric boilers EOU comply with GOST standards, which is confirmed by the relevant documentation.
Comparison of EOC and gas boilers
For many years, natural gas has been the number one energy source. It was used both for domestic purposes and on an industrial scale. The disadvantages of gas boilers became apparent after the appearance of electric EOS designed for autonomous operation. Gas equipment is inferior in several areas at once:
- lower efficiency value;
- boiler operation is accompanied by emissions of harmful substances;
- high fire hazard;
- dependence on the gas main.
Advantages of installing an electric boiler
Among the main advantages are the following:
- Electric boilers can be installed anywhere, provided that it has access to the network. Other factors such as ceiling height or room size are irrelevant.
- Installing the boiler is very simple and quick. The work is not difficult. The requirements for using the equipment are similar to working with a boiler.
An electric heating boiler is an excellent replacement for gas equipment. The house is heated quickly, and you do not need to have special skills to operate the boiler.
Design features
The role of heating elements is played by two electrodes made of a special heat-resistant alloy. The function of the coolant, most often, is carried out by water.Taking into account the permissible standard heat losses, in order to create a comfortable temperature in a room with a volume of 65 m3, 1 kW of electricity is enough.
The main units of the installation:
- boiler equipped with automation;
- pump for circulation of the coolant (depending on the modification);
- expansion tank to collect excess liquid;
- pressure gauge, outlet valve;
- mud filter;
- automatic machine for current from 1A and an electromagnetic starter.
Power
The main indicator of electric boilers for hot water heating is power. In this dependence, the connection can be carried out both to a 220V source (single-phase circuit) and to a higher 380V (three-phase circuit).
What are the advantages of this equipment
Energy-saving electric boilers for heating a house or city apartment appeared relatively recently and almost immediately gained great popularity. As mentioned earlier, there are many reasons for this, but first, let's understand how this system works.
The principle of operation of the equipment
The operation of any installation of such a plan is based on the movement of ions between two electrodes with different potentials, in other words, between plus and minus.
As you know from the initial course of physics, any movement is inevitably accompanied by the release of a certain amount of thermal energy. It is due to this very heating that the energy-saving heating installation EOU works.
Depending on the power, electrical installations can be connected both according to a single-phase 220V circuit, and using a three-phase wiring with a voltage of 380V. In the capacity of a heat exchanger, in this case, the liquid circulating directly in the system acts.
Why are installations good?
- The design of this equipment does not provide for the presence of a combustion chamber equipped with a heat exchanger.... To install the electrodes, a lot of space is not required, as a result, the dimensions of the unit slightly exceed the diameter of the pipes used in the wiring of the system.
- Energy-saving heating electrical installation EOU, will work stably at almost any voltage... Sudden voltage drops are not terrible for her, by and large there is practically nothing to burn there, therefore, such installations do not require the installation of voltage stabilizers.
- Such boilers do not require a separate room.... The dimensions of the unit make it possible to mount it in any room, which is especially convenient in city apartments or houses with a small square footage.
- Since electrical energy is used for heating, the energy-saving heating installation does not require additional ventilation in the room.
- If we talk about security, then here it has one of the highest levels.... If the installation instructions were followed correctly, there is nothing to be afraid of. Since there is no open flame or filament here.
- The operation of such a system does not require any special knowledge, it is simple and accessible to anyone.
- As for the installation of equipment and commissioning of the boiler, an average electrician with basic professional knowledge of electrical engineering can do this work with his own hands.... To do this, he will need, in addition to keys, pliers and a screwdriver, the pump itself for pumping fluid into the system and an ammeter.
Disadvantages of installations
- According to most experts, an energy-saving heating installation works effectively only on small areas. Certainly, in buildings with a large quadrature such installations can be mounted several, but in this case it will be difficult to call such equipment economical.
- Unlike double-circuit gas or solid fuel boilers, in units of this type, the function of heating water for domestic needs is not provided at all. They are intended exclusively for heating purposes.
Principle of operation
The EOU is a direct-acting device, that is, there are no intermediate components in it. The operation of a water heating boiler is based on the movement of ions between a pair of electrodes with a frequency of 50 oscillations per second. And since any chaotic movement of electrically charged particles produces thermal energy, the liquid is heated.
A large temperature difference is created at the inlet and outlet of the electrode boiler, which forces the heated liquid to rush up the direct supply pipeline to a height of 25-30 meters (depending on the boiler model).
The units operate in automatic mode, temperature control is carried out by a special sensor connected to the relay. The continuous operating time of the equipment is 2 to 9 hours. The heating chamber of the installation has a small capacity, which contributes to the instant heating of the coolant to 95 ° C.
EOU are designed for closed water heating systems of all types and can serve as both the main and auxiliary heat source.
It is allowed to use rainwater, melt water and frost-resistant liquids as a heat carrier.
The boiler can be operated with or without a water circulation pump. In the first case, electricity consumption will be reduced. The control over the operation of the EOU is carried out by a thermostat, which, as the air temperature changes, disconnects or connects the installation. Thus, the room temperature is maintained at the set level.
How to choose an economical electric boiler
Thanks to the modern development of technologies in the arrangement of residential premises and construction, it makes it possible to use heating equipment of various functionality. If there is no gas in the house, then many people think about an alternative heating option.
The best option might be an energy-efficient electric boiler. The equipment is practical and convenient, therefore it is highly popular among consumers.
The room is heated by an electric boiler in automatic mode. In the absence of owners, you can adjust the optimal heating mode and return home to a comfortable temperature. The performance of such equipment is high and has many positive characteristics. Let's take a closer look at the technical characteristics of electric heating boilers.
Installation of EOU
To install an energy-saving water heating device, fittings and connecting elements are used, which are traditionally used during plumbing work (pipes, hoses, couplings, adapters, etc.). The installation of an energy-saving electrical installation in the heating system is no different from the installation of other types of boilers:
- outlet temperature is about 95 ° C;
- operating voltage range 220–380 V;
- single-phase installation length 300 mm, diameter 43 mm, weight 2 kg;
- inlet connecting size G1 ″, outlet G1¼ ″;
- installation length of three-phase type 400 mm, diameter 106 mm, weight 7 kg;
- inlet connection size G1¼ ″, outlet G1¼ ″.
Possible mounting options
The inlet of the installation is connected to the return line, while the outlet is mounted to the flow of the heating system. If one or more boilers are already operating in the system, the installation of the energy-saving option is carried out in parallel with the existing devices. There are several options for installing the system:
- two-wire circuit with top wiring (natural water circulation);
- single-wire circuit with bottom wiring (forced water circulation);
- parallel circuit, when the ECU is connected to the heating system, mounted earlier;
- parallel circuit, when two or more EOU are connected to the system.
Mandatory requirements
When installing an energy-saving water heating boiler, it is necessary to provide for the installation of an electricity meter, applied to a current strength of 1A.The cross-section of the electrical cable must have the same value as indicated in the instructions. The installation of the ground loop is also a mandatory requirement.
Features of single-circuit electric boilers
Single-circuit boilers are often used to heat country houses. Energy is consumed only for heating heat, so the power does not differ from the presented indicators.
The advantages of such equipment:
- Small size. Electric boilers are powerful but don't take up much space.
- High performance. The heat carrier heats up quickly, and little energy is expended.
- Heats even a large house, despite its compact size.
Savings from the use of EOC
Energy-saving heating systems comply with all environmental and fire safety standards, operate silently, without emitting substances harmful to human health.
The use of EOU allows you to optimize the consumption of electrical energy, and where rationalism operates, the family budget is saved there. Thermostats installed in each room allow you to regulate the temperature in the range from 5 to 30 ° C. When the temperature drops by only 1-2 degrees, electricity costs are reduced by 5-6%. A more flexible approach to whole-home thermal management will result in 35-50% savings.
If desired, any temperature schedule can be programmed for a heating system with an EOC, according to which the automation will turn off one or a group of rooms.
Benefits of EOU
The energy-saving heating system EOU has the following advantages:
- profitability;
- compactness;
- autonomy;
- reliability;
- durability;
- no harmful waste;
- fire safety.
Arguments in favor of EOU boilers (compared to gas installations)
- The rate of growth in the price of natural gas is higher than the rate of growth in the cost of electricity;
- At peak loads, the pressure in the gas networks does not allow high-quality heating of the premises;
- Lack of a permitting procedure for the installation of equipment.
Examples of using installations
Energy-saving heating electrical installation - ideal for stalls and pavilions located far from heating mains.
The use of electrical installations will have a beneficial effect on the condition of old buildings in the historical parts of cities, where it is impermissible to carry out expensive and time-consuming work on the laying of heating routes. After all, such mansions and old palace buildings are often surrounded by magnificent parks. In such cases, energy efficient installations can be the optimal solution for protecting historic areas.
In city apartments, EOU can be used as backup equipment. They will provide a comfortable stay on cold days, which are not uncommon in spring and autumn, when the heating is turned off. Russian winters are long and harsh, during especially critical periods when the centralized system does not provide adequate heat, the EOC will automatically warm the air to the required temperature.
EOU as a backup heating equipment can be used in large rooms with insufficient thermal insulation, for example, in warehouses, production halls, exhibition pavilions, concert halls and sports halls.
Which electric boiler is the most economical
Residents of houses that are located in areas where there are gas mains have many advantages. This is especially true in the winter period, when gas boilers begin to work. Residents of other areas need to look for alternative heating options.
Gas is one of the most readily available fuels. But gas equipment, while easy to use, is unsafe.Those residents who do not have gas can choose an electric boiler to heat their home. You should find out which boiler is the most economical and easy to use.
