Overview of gas boilers Korea star

The Korea Star gas boiler is a product of the South Korean company of the same name, which is not inferior in quality to the best European counterparts. At the same time, Korean boilers are 20–30% cheaper than their competitors. KoreaStar is not the only gas equipment manufacturer in South Korea.

In Russia, heaters of various South Korean brands are willingly bought – Daewoo, Navien, Olympia, etc. They are united by a high level of production technologies, affordable cost and adaptability to difficult Russian conditions. Koreastar is no exception – the domestic consumer managed to evaluate the endurance and reliability of the company’s boilers.

About Us

KoreaStar is an enterprise founded in 2003. It has been on the Russian market since 2004. The company produces a variety of household and industrial equipment. One of the activities is the production of gas heaters, which are sold all over the world. The brand supplies several dozen models of different designs and capacities to Russia. When assembling, Korean and European components are used that comply with ISO 900 standards. The Korean Star works closely with the German company Wilo. The latter supplies circulation pumps to its eastern partner.

Design features

• Devices for 10–20 kW are equipped with a copper heat exchanger of 24 kW, so when the DHW circuit is turned on, they are not afraid of extreme loads. Their water capacity is 13,6 l/min.
• Thanks to the double protection of the heat exchanger, it does not overheat, and the service life is extended.
• Combustion chamber in two versions – closed (PREMIUM E) and open (PREMIUM A).
• Economical fuel consumption.
• Equipped with an LCD screen. Self-diagnosis.
• Modulated fire intensity.
• Equipped with WILO pump (German production), anti-blocking system.
• Freeze protection system.
• Connecting the remote control, room thermostat.

Advantages of Korean equipment

• Does not respond to pressure drops in the gas line.
• High value of efficiency, efficient fuel combustion.
• A wide range of models, there are wall and floor models, with one and two circuits.
• Stylish design. Compactness.
• Equipped with built-in fuses that guarantee the safety of the equipment in case of emergency.
• They are converted to liquefied gas, jets are included in the kit.
• They can provide the house with hot water.
• Ability to select the operating mode. Temperature setting.

Features of operation

Boilers “KoreaStar”, being productive and reliable, have advantages and disadvantages typical for any equipment with a closed firebox:

• Noise. The reason is the operation of the fans. With their help, air is injected and removed from the coaxial chimney. A distinctive feature of all forced draft burners is their noisy operation. It is advisable to install such heaters away from living rooms.
• The water in the hot water supply is heated separately from the coolant. The three-way solenoid valve increases the heating rate, ensures a uniform supply of water at any pressure in the water pipes.
• When the coolant cools down to +5 °C, the boiler automatically starts, preventing the heating system from defrosting.
• Energy dependence. The instructions for use of KoreaStar heaters say that they are able to function with power surges up to 15% of the nominal value. But in practice, there are problems, the controller board fails. Installing an uninterruptible power supply will help prevent breakdowns.
• Before connecting the device, you need to obtain permission, order project documentation from the gas service.

Power setting

After starting the device, you need to press and hold for 5 seconds. buttons to adjust the temperature to enter the setting mode. Adjust the gas pressure by decreasing and increasing the pressure using the DHW adjustment buttons. While the setting is in progress, a number will appear on the screen. This display designation is the value of the minimum power in percent: 44–54. When the pressure gauge shows the required pressure value, press the RESET button, the parameters will be saved.

When setting the operating power, set the gas pressure with the buttons that regulate the temperature of the heating water. The display will show the power value as a percentage: 0–99. Having set the required value, press RESET, save the parameters, exit the settings mode.

Installation

Before installing the machine, make sure it is powered by natural gas. If the use of liquefied gas is supposed to be used, it is necessary to readjust the heater – this should be done by a specialist. Power supply with 220 V/50 Hz parameters must be supplied to the place of installation of volatile models. Deviation of parameters from the norm leads to a decrease in productivity, a reduction in service life.

It is forbidden to connect other electrical appliances to the boiler power supply. It is also forbidden to use extension cords and adapters when connecting. Failure to comply with safety regulations may result in a fire.

Requirements for premises

The room in which the gas equipment is to be installed should be equipped with forced ventilation. Moreover, door and window openings cannot be classified as such if they do not have devices that ensure the constant movement of the air flow – fans, holes in the door leaf, etc. When the heater is put into operation, it is forbidden to carry out construction work in the room that can change the design of the ventilation, thereby affecting the volumes of incoming oxygen.

In the boiler room it is prohibited:

• Store flammable substances and materials.
• Store chemically active substances – chlorine, ammonia, acids, etc.
• Place heaters and air conditioners near the boiler.
• Install equipment near stairs, in wall openings, near windows and emergency exits.

Models overview

KoreaStar ACE

The series is represented by 2-circuit heaters Atmo and Turbo, which differ in the design of the furnace. “Atmo” – atmospheric type, “Turbo” – turbocharged.

Reviews

Premium 24E: Raisa P., Dedovsk

Liked its features and affordable price. Worked well, kept the temperature at a given level. But in the second year of operation, the pressure switch broke, which could not be found. And it’s good that it wasn’t winter, otherwise it would have been freezing. 

Premium-24E Turbo: Leonid Zh., Kostroma

Works for two years. During this time, twice showed an error – a failure of the work. It was fixed with a reboot. Before the start of the heating season, the DHW flow sensor broke, so they could not turn on the boiler: information about the supply of hot water was constantly on the screen. The master, arriving two days later – due to workload, changed the spare part for free, under warranty. Pros – compact, hangs on the wall and does not interfere with anyone. No need to build a chimney. Consumes little electricity. Of the minuses – depends on the mains. It is difficult to regulate the temperature of the water with a small pressure. Lack of specialists, you have to wait a long time for the master.

The efforts of the manufacturer and its marketers were crowned with success – KoreaStar products have won their niche in the Russian market. Consumers are attracted by the affordable cost and reliability of Korean boilers. There are usually no problems with the operation of equipment, but there are problems with maintenance and repair. This is due to the insufficient coverage of the territory of the Russian Federation by KoreaStar service centers.
