Koreastar is known for striving to adapt its products to the operating conditions specific to the market. Boilers distributed in Russia tolerate sub-zero temperatures (up to -40 degrees) with minimal increase in gas consumption. This makes the devices economical in cold winters.
Features of Koreastar boilers
The company produces dual-circuit units designed for the implementation of two tasks - heating the home and supplying hot water. Floor devices are also available for wall mounting. The liquid for heating the home and for domestic needs in most devices is prepared separately. To neutralize the associated slowdown in heating, the products are equipped with a solenoid valve with three strokes.
When the coolant is cooled to +5 degrees, the gas boiler is switched on by means of automation. This prevents freezing of water in the pipes. Reducing gas pressure (up to a certain limit: at least 4 mbar) and voltage drops do not affect the stability of the boiler.
Specifications
The power of gas boilers Koreastar, depending on their device and the volume of water produced, varies in the range from 10 to 40 kW. Parameter setting and operation control are realized remotely using the remote control. The microprocessor board withstands power surges. Also, the boilers are equipped with an external thermostat, whose function is to turn off the water heating when the temperature reaches the desired level. The design uses German-made circulation pumps and a liquid crystal display.
The performance of a specific boiler model Koreastar is indicated in the instructions. For the least powerful variations, it is approximately 13 l / min. The heat exchanger is equipped with additional protection, due to which the unit lasts longer. Some types of boilers are available in versions with a closed and open combustion chamber, others - only in the first version.
Advantages and disadvantages
When choosing a Koreastar boiler, buyers are attracted by the acceptable cost of these devices and the price-quality ratio: few can afford a German-made unit. Well-coordinated work in cold winters inherent in a significant part of the territory of Russia also interests private house owners.
Other advantages of these devices are:
- low noise level from a working pump;
- high-quality automatic control unit;
- climate control option;
- optimization of gas supply (initiation - when the burner ignites, termination - when it goes out), which saves fuel;
- the use of a device that prevents smoke in the room;
- mechanism preventing the coolant from freezing.
The minus is that sometimes voltage surges still cause malfunctions of the microprocessor board, despite the manufacturer's instructions about stable operation with differences within 15% on both sides of the nominal. Such incidents can be prevented by installing an uninterruptible power supply.
When the owner of a boiler with a closed chamber turns on the device, it may encounter noise - this is due to the type of burner used. Such a unit should be mounted in a separately equipped boiler room.
Installation and operation
The boiler connection diagram is given in the instructions. It is determined by the features of the device of this model. Some units are volatile, others do not need power.In the first case, a voltage of 220 V with a frequency of 50 Hz should be connected to the connection point. Do not use tees, extension cords, or connect other devices to the source. If a particular model needs to be provided with liquefied gas, a readjustment is carried out by inviting a master.
In the boiler room it is necessary to provide forced ventilation using equipment that creates continuous movement of air flows. The use of gas fuel imposes a ban on the storage of chemically active and fire hazardous compounds and materials in the room where the boiler is installed. Do not place the unit near a window, a flight of stairs or in an aperture of a wall, or place heaters and air conditioning appliances near it. In case of malfunctions, the error code is displayed on the display (numbers are explained in the instructions).
Selection rules
When choosing a boiler, you first need to calculate what power is required to service the home. The roughest method is based on the area: it is assumed that for every 10 square meters 1 kilowatt of energy is needed. To achieve greater accuracy of calculations, it is necessary to take into account the climatic features of the region where the dwelling is located, the material of the walls and the influence of various sources of heat loss. The manufacturer indicates the operation with which dimensions of the premises this or that model with a certain power value is designed.
Products equipped with a bithermic heat exchanger heat up the liquid faster, but do not last as long as the versions with two insulated coils. 3 cubic meters of gas per hour is spent on heating a living space of 300 m2. With smaller dimensions of the premises, the consumption will be lower. Using the economy mode reduces costs by almost half.
Popular models
Actively positioned ranges are Buran and the parapet non-volatile President. But the earlier series continue to be sold: Ace and Premium include models with a closed camera (Turbo) and wall-mounted devices with an open (Atmo). The Bravo Turbo range only includes units with a closed camera, designed to be placed on the floor. The company also produces indirect heating boilers connected to a floor or pendant boiler.
Premium 16E
The label 16E in the name indicates that the maximum power of the unit is 16 kW, it has a closed combustion chamber and is placed on the floor. As with other manufacturers, the name of a particular boiler model informs about some of its characteristics. The number indicates the power indicator, letter A accompanies mounted boilers with an open chamber, and E - floor with a closed one. In economy mode, device 16E consumes approximately 8.15 kW. It will effectively heat 160 m2 of living space. The weight of the boiler is 32 kg.
The efficiency of Premium devices is 93.1%. All of them are equipped with two heat exchangers: the one that works for heating is made of copper, and the heater for domestic water is made of steel. Productivity allows you to prepare a shower with a cost of up to 13 liters per minute. Adjustable parameters are displayed on the LCD screen. A bypass valve protects the unit against water hammer during pressure surges. Premium models consume both natural gas and liquefied gas.
Koreastar Ace
This series is sharpened for the fastest heating of water. The devices have a bithermic copper heat exchanger. When operating in water heating mode, even low-power options show a capacity of 10 liters per minute. Boilers have a built-in bypass circuit (bypass), which makes them suitable for use with radiator equipment equipped with temperature controllers. The efficiency of the models is in the range of 90-91.2%, the power is in the range from 10 to 32 kW.
Koreastar boilers are well suited for servicing rooms of up to 320 m2, while also providing hot water. The devices are equipped with units that ensure safe operation: protection against freezing of the coolant, against water hammer, anti-blocking of the main components.
