Gas equipment is becoming more and more common, as it is affordable, affordable and convenient to operate. From this point of view, the Korean-made Daewoo gas boiler belongs to the middle price category and is popular with the Russian consumer.
Types of gas boilers Daewoo
Turbocharged boilers
The device can be located in any room. The device is light enough, about 26 kg, so it does not overload the wall. It is placed more often in the kitchen in a suspended state. Since the boiler is small in size, a separate room is not required for it, even a kitchen cabinet is quite suitable for placement.
The advantages of a turbocharged boiler:
- compactness;
- light weight;
- the necessary mounts are included;
- remote control available;
- Efficiency - 91%;
- economical fuel consumption.
Daewoo boiler must be connected to electricity. This can be considered its main drawback. The device contains a coaxial chimney, through which oxygen, necessary for gas combustion, enters and harmful substances are removed. Closed firebox.
Technical features:
- pressure - 3 atmospheres for heating, 7 - for hot water supply;
- electricity consumption - 0.1 kW per hour;
- power - 11.6 or 15.1 kW;
- the highest water temperature for heating is 85, for hot water supply - 60.
The specificity of devices may differ depending on a particular model.
Atmospheric boilers
The Deo boiler of atmospheric type is characterized by an open type of burner. When installing it, it is important to observe the safety precautions of gas equipment. The hinged unit is installed in a separate boiler room; the room must be appropriately equipped. Basic requirements: forced ventilation, sufficient room size, ceiling height.
Advantages of atmospheric units:
- safety;
- long service life;
- uncomplicated device;
- silent work;
- breakdowns are observed less often than turbocharged ones;
- independent of electricity;
- heating of a large area - up to 200 m2.
The disadvantages of the Daewoo atmospheric gas boiler can be considered the mandatory presence of a chimney and a constant supply of fresh air.
The technical characteristics of the atmospheric type Daewoo boiler do not differ from the characteristics of the turbocharged type. Only their power can vary - from 12.8 to 23.3 kW.
Double-circuit
Models with two circuits are produced by the company "DEU Gazboiler". They evenly heat water, have independent heat exchangers, and are easy to install and maintain. The design of these devices has the following features:
- the first circuit is made of copper;
- the second is lamellar;
- heat exchangers have an independent device;
- water heating does not depend on the number of water intake points and pressure;
- convenient control.
The process of creating boilers is controlled at every stage. The products comply with international quality standards.
Main characteristics
The devices represent a mini-boiler room that can heat a room up to 200 m2.Features of atmospheric and turbocharged mechanisms:
- The power is automatically adjusted.
- The circuits function independently of each other, separately.
- The burners are made of stainless steel.
- Microprocessor control makes it possible to monitor the operation of the boiler from anywhere in the house.
- Convenient remote control.
- Circular 2-way pump with ball switch.
- Uniform heating of water.
- Automatic testing of the system to identify faults.
Despite the ease of use, equipment owners note that some parts have to be replaced frequently due to emerging malfunctions.
The principle of operation of gas boilers Daewoo
Air masses enter the boiler through a special air duct. Inside there is a built-in fan that runs at high speed when ventilating the chamber where fuel is burned. Then the speed of revolutions decreases, the valve opens, the gas is supplied to the chamber, where it is mixed with air. High voltage is applied to the electrodes, the gas ignites. This is detected by an infrared sensor that sends a signal to the control board. The whole process is controlled by the system.
The Daewoo gas boiler works smoothly, the power is automatically regulated. Combustion, the gas heats up a copper heat exchanger, which transfers heat to the coolant. An even temperature distribution is achieved by the operation of the circulation pump. The boiler is completely sealed, the products of its combustion are discharged outside through the chimney.
Boiler design and main control devices
The design features of the Daewoo boiler are not particularly difficult. The boiler has the following main elements:
- the combustion chamber;
- double-circuit heat exchanger;
- circulation pump - one or two;
- measuring instruments - manometer, thermometer, thermostat.
The devices are available in the form of boilers. When heated, the water circulates inside the apparatus, the work of the entire system is performed. Wall-mounted models take up a small area, are convenient and allow owners to heat the room with a compact model.
The boiler has a built-in control unit. With the help of a backlit digital console, you can see all the information about the operation of the equipment and control the process. Also, the operation of the device is programmed by means of an electronic daily timer.
Maintenance and operation
The boiler works automatically, it does not need to be adjusted every day. But at the very beginning, it is necessary to test the equipment for operating modes. In this case, it is imperative to follow the instructions.
- Install thermostats.
- Indicate temperature limits via display.
- Set the parameters of the water supply system.
- Set up automatic functions: air extraction, disinfection, equipment self-diagnosis.
- Connect to electricity.
All work related to the installation of a gas boiler must be carried out by a specialist. When switching from winter to summer season and vice versa, the parameters are reconfigured. It is periodically required to replace some elements of the boiler, make repairs, clean the chimney and burner.
