The DEU gas boiler is a product of the Korean company DAEWOO Gasboiler, which is a division of the world-famous Daewoo Corporation. The main advantage of their products is their affordable price, which attracts our consumers. But as they operate, the owners of Korean boilers face various kinds of technical problems and malfunctions. Consumers also complain about the noise emitted by gas devices manufactured by DEU, although the manufacturer claims the silent operation of their boilers.
About company
The year Daewoo was founded is 1967. Translated, the name means "The Great Universe." Today it is a whole group of companies that owns its own research centers that develop and patent innovative technologies. For example, for the first time, the company applied an adapted ignition system - MICOM electronics controls the ignition of the burner. The company released its first gas boiler in 1988. It is a major exporter - Daewoo products are supplied to one and a half dozen countries.
Design features
The double-circuit wall-mounted apparatus is a mini-boiler room that provides autonomous heating and hot water supply (DHW). The DEU Gazboiler company produces atmospheric and turbocharged boilers. The device of double-circuit mounted models is characterized by the same technical characteristics and structural solutions:
• Separate heat exchangers.
• Primary heat exchanger - made of high quality copper.
• Burner material - stainless steel.
• Secondary heat exchanger (for domestic hot water) - high-speed, plate-type.
• Automatic power control - changes smoothly, depending on the heat load.
• Simple and convenient operation - due to microprocessor control.
• Intelligent adjustment - MICOM microchip.
• There are control systems and a remote control with a built-in temperature sensor and a liquid crystal display. The heater is easy to control from any room in the house.
• Use of a circular pump. Thanks to the good parameters and simple design, the developers managed to replace the three-way valve. A two-way pump was developed and introduced, in which a ball-switch system was used. The latter has high bandwidth. Hot water heats evenly. And most importantly, the number of users does not affect the degree of heating - no matter how many water intake points are open simultaneously, the water maintains a stable temperature. The pressure in the water pipes also does not affect the heating of the water.
• Self-diagnosis. The equipment automatically detects problems, and the test results are displayed on a remote control unit equipped with a digital display.
Among the unique advantages of Korean heaters is a simple design. Experts assure that their disassembly, repair, adjustment and maintenance does not cause any difficulties.
Estimated price of DEU brand boilers is 15,000-25,000 rubles.
Design
Structurally, the device consists of several component groups. One of the main elements is the burner. It serves the fuel and transfers its energy to the heat exchanger, which is connected to 1 or 2 circulation pumps. These components make up the infrastructure through which the process flows.
To control the operation of the equipment, the design includes a thermostat, pressure gauge and thermometer. The listed devices provide optimum performance.
Atmospheric boilers
A characteristic feature of atmospheric mounted attachments is an open firebox. Oxygen is supplied to the burner due to natural circulation. Exhaust gases are removed in the traditional way - through the chimney. The purpose of such devices is autonomous heating of housing up to 200 m2. Thanks to thoughtful design solutions, atmospheric modifications have the following advantages:
• Safe.
• Long service life.
• Simple assemblies and parts.
• Silent burning of the burner - in any case, according to the manufacturer.
When mounting the attachment, it is important to follow the rules for connecting gas equipment. During operation, oxygen is consumed in the boiler room. Therefore, the room in which the device is installed with an open firebox must comply with technical safety standards regarding the minimum area, ceiling height, forced ventilation, etc.
Turbocharged boilers
Unlike atmospheric ones, turbocharged models have a closed firebox. Combustion air is forced. Such devices require a coaxial chimney. The main plus of the turbocharged versions is the ability to install in any room. It is usually placed in the kitchen. A separate boiler room is not required. The device is compact and can fit in a kitchen cabinet. It weighs about 26 kg, so it can be hung on any wall, even drywall. The kit comes with everything you need for mounting. All products are also equipped with remote controls. With the help of the latter, you can remotely adjust equipment parameters.
The principle of operation involves the organization of a forced challenge. To divert exhaust gases, electricity is needed. Turbocharged devices are characterized by decent efficiency (91%) and fuel economy. They have two circuits, and their power is 11.6 or 15.1 kW, and can heat housing with an area of 115 and 151 square meters. Important technical characteristics of turbocharged boilers of the DEU brand:
• Maximum water pressure. Heating - 3 atm. DHW - 7 atm.
• Energy consumption 0.1 kW / h.
• Maximum water temperature. Heating - 85 ° C. DHW - 60 ° C.
Installation and connection
Installation of Daewoo Gasboiler equipment does not cause problems for specialists, but problems with self-installation can occur. Dealers selling products of a Korean company have the right to refuse repair under warranty if the consumer himself was engaged in the installation. It should be noted that when strapping, it is necessary to connect to electrical networks and install thermostats. For the implementation of such operations, special clearance and knowledge of the PUE are required.
The main thing during installation is strict adherence to the recommendations given by the manufacturer. In the instructions, you can familiarize yourself with the connection diagram.
Which is better - atmospheric or turbocharged?
In apartments it is better to place turbocharged models connected to a coaxial chimney. For them, the requirements and fire safety rules are less stringent than for atmospheric counterparts.
Turbocharged versions have a drawback - they are volatile. Atmospheric - non-volatile, they are not afraid of power outages. To make sure that there is no light, owners of turbocharged models install backup power or a generator. Both options represent a worthy alternative to more expensive European products.

User's manual
During operation, the user deals with different groups of parameters. The work will be built automatically - a person does not have to adjust it daily. But it is necessary at the beginning of operation to drive the device according to different operating modes - to test for specific needs. It is necessary to set the heating modes by setting the temperature limits. Similarly set the parameters of the water supply. The instructions noted - frost protection in auto mode only starts when the corresponding mode is turned on. This subtlety is taken into account when restructuring performance from the winter season to the summer season and vice versa.
Maintenance Instructions
The user must fine-tune the automatic functions. Korean gas heaters have functions - air exhaustion, tank disinfection, self-diagnosis and others. During operation, the owner of the equipment should be ready to perform some simple maintenance operations - cleaning the chimney, burner, etc. Spare parts have to be purchased as needed. The typical list of infrastructure elements includes a heat exchanger, expansion tank, pipes, fans, pipes, accessories.
Reviews
Gasboiler DGB-160 MSC: Mikhail D., Belgorod.
I have been using it for three years. Of the pluses - saving gas, beautiful in appearance. Cons - it makes noise when it warms the water. Still bad - when the light turns off, it does not work. The first thing I liked was that gas bills became less. Few took places - hanging on the wall, does not bother anyone. Convenient ignition - electronic. There is a remote control with backlight. In order not to turn off during interruptions with the light, I had to put backup power. It does not turn on at low water pressure. Simple installation, nothing special is needed - ordinary metal-plastic pipes, fasteners, taps. No welding work. The cost paid off in two winters.
DGB-250MSC: Alina E., Altai Territory.
Bought, having a bit for beautiful design and attractive price. I can’t say anything good about work. Perhaps we came across a factory marriage. He shook his nerves - any errors were constantly displayed - either there wasn’t enough water for him, then the switch was turned on for more than an hour and a half, then the electric current was different. In our village there is no service, it’s not easy to call the master, so often in winter it was just necessary to sit near the boiler.
DEU boilers are compact heating devices that are convenient to use in apartments and private homes. Despite its convenient operation and quiet operation, Daewoo products cannot be called a leader in consumer demand. Relating to the middle class, Korean equipment is notable for its affordable cost - this is the main factor encouraging domestic consumers to buy it.
