Gas equipment is becoming increasingly common, as it has accessibility, reasonable cost, convenient management. From this point of view, a Korean-made Daewoo gas boiler belongs to the middle price category and is popular among Russian consumers.
Types of gas boilers Daewoo
Turbocharged boilers
The device can be located in any room. The device is quite light, about 26 kg, so it does not create an excessive load on the wall. It is placed more often in the kitchen in a suspended state. Since the boiler is small, a separate room is not required for it, even a kitchen cabinet is quite suitable for placement.
Advantages of a turbocharged boiler:
- compactness;
- light weight;
- necessary fasteners are included;
- available remote control;
- Efficiency - 91%;
- economical fuel consumption.
The Daewoo boiler must be connected to electricity. This can be considered its main drawback. The device contains a coaxial chimney through which oxygen is supplied, which is necessary for gas combustion, and harmful substances are removed. The furnace is closed.
Technical features:
- pressure - 3 atmospheres for heating, 7 - for domestic hot water;
- electricity consumption - 0.1 kW per hour;
- power - 11.6 or 15.1 kW;
- the highest water temperature for heating is 85, for domestic hot water - 60.
The specifics of the devices may vary depending on a particular model.
Atmospheric boilers
The atmospheric-type Deo boiler is characterized by an open type of burner. When installing it, it is important that the safety equipment for gas equipment is observed. The mounted unit is installed in a separate boiler room, the room must be suitably equipped. Basic requirements: forced ventilation, sufficient room size, ceiling height.
Advantages of atmospheric units:
- safety;
- long service life;
- simple device;
- silent work;
- breakdowns are less common than turbocharged ones;
- independent of electricity;
- heating a large area - up to 200 m2.
The disadvantages of the atmospheric gas boiler Daewoo can be considered the mandatory presence of a chimney and a constant influx 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 DEU Gazboiler company. They evenly heat water, have heat exchangers independent of each other, and are distinguished by simple installation and maintenance. The design of these devices is characterized by 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 management.
The process of creating boilers is controlled at each stage. Products comply with international quality standards.
Main characteristics
The devices are a mini-boiler room, which can heat the room up to 200 m2. Features of atmospheric and turbocharged mechanisms:
- Power is automatically adjusted.
- The circuits operate 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 two-way pump with ball switch.
- Uniform heating of water.
- Automatic system testing for troubleshooting.
Despite the ease of use, equipment owners note that some parts often have to be replaced due to malfunctions.
The principle of operation of gas boilers Daewoo
Air masses enter the boiler through a special duct. Inside there is a built-in fan that works at high speed when ventilating the chamber where the fuel burns. Then the speed of revolutions decreases, the valve opens, gas is supplied to the chamber, where it is mixed with air. High voltage is applied to the electrodes, 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.
Daewoo gas boiler runs smoothly, power is automatically adjusted. By burning, the gas heats the copper heat exchanger, which transfers heat to the coolant. Even temperature distribution is achieved through the operation of the circulation pump. The boiler is completely tight, its combustion products are discharged out through the chimney.
Boiler design and basic controls
The design features of the Daewoo boiler are not particularly difficult. The boiler has the following main elements:
- the combustion chamber;
- dual-circuit heat exchanger;
- circulation pump - one or two;
- measuring instruments - manometer, thermometer, thermostat.
Devices are available in the form of boilers. When heated, water circulates inside the apparatus, the entire system is in operation. Wall-mounted models occupy a small area, are convenient and allow owners to heat the room using a compact model.
The boiler has an integrated control unit. Using a digital remote control with backlight, 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 operates automatically; it does not need to be configured every day. But at the very beginning it is necessary to test the equipment according to operating conditions. In this case, compliance with the instructions is mandatory.
- Install thermostats.
- Indicate temperature limits via display.
- Set the parameters of the water supply system.
- Set automatic functions: air exhaust, disinfection, self-diagnosis of equipment.
- Connect to electricity.
All work associated with the installation of a gas boiler must be carried out by a specialist. When switching from the winter season to the summer and vice versa, the parameters are reconfigured. Periodically, it is required to replace some elements of the boiler, to repair, clean the chimney and burner.
