Gas boiler "Celtic" - the products of the South Korean giant, which produces a variety of household appliances. Celtic heaters use the company's own innovative developments to increase their productivity and efficiency. Korean wall-mounted boilers are universal - they are suitable for small houses with an area of 100-150 square meters. m, and for cottages up to 400 square meters. m
About company.The main activity of the South Korean company DAESUNG CELTIC (Gas Boiler) is the development and production of heating equipment. The company was founded in 1947. It is the largest producer of South Korea. The priority in gas heaters is the production of wall-mounted double-circuit boilers.
Features of the mounted Celtic boilers
The double-circuit mounted apparatus "Celtic" is stuffed with all automation. Koreans did not stint on innovative developments and automation of all processes that occur during the operation of gas equipment. Automation controls breakdowns (there is a self-diagnosis system), ignition, flame intensity, pressure - a person does not need to interfere with the operation of "smart" equipment.
Combustion chamber device
All Celtic wall-mounted boilers have a closed firebox. A modular pressurized burner is installed. Air is pumped by a fan from the street. Similarly, with the help of a fan, the exhaust gases are discharged. The supply of oxygen-gas mixture is regulated by the control unit. By changing the ratio of products, it smoothly changes the temperature in the right direction.
DHW supply
The boiler has two heat exchangers. The heating medium and water in the DHW are heated separately, each circuit has its own temperature. This approach allows to increase the heating rate and energy efficiency of the device. The controller sets the hot water settings. For comfortable use of hot water, the heating temperature and a number of other parameters are indicated. Thanks to the three-way valve, a stable temperature in the hot water supply is maintained, it is not affected by the pressure in the water pipes or the number of active points of water intake.
Security questions
The safety system in the Celtic DS Platinum models prevents all dangerous situations. It includes sensors that monitor the temperature and pressure of the coolant, the draft of the chimney. There are valves responsible for the discharge of excess coolant. Condensation models also provide for monitoring gas pressure drops and overheating. There is frost protection.
Condensing module
All premium versions are equipped with a condensing module. The energy of the exhaust gases is accumulated and used to heat the coolant. Due to additional energy, efficiency increases, in such devices it reaches 105%.
Uninterrupted operation
Innovative technologies allow you to create ultra-reliable equipment. At first, Celtic boilers function almost without failures or breakdowns. But only subject to proper installation, configuration and timely maintenance. Platinum models are equipped with an alternating current generator that protects all volatile components from power surges. When the light is turned off, the equipment settings will be saved. When the unit turns on, the mode set immediately before the shutdown is launched.
Self diagnosis
Faults detected by the self-diagnosis system are displayed on the display in the form of codes. To decrypt them, you need an instruction - it contains a list of possible error codes and their decryption. This simplifies the detection of breakdowns and maintenance of equipment.
Installation
When installing the gas equipment "Celtic" you need to remember:
- All models are volatile, they require electricity.
- Tying is performed as standard: heating and hot water pipes are connected to the apparatus. For watering, a water treatment system is installed.
- Permission is taken for installation. Since boilers use a closed firebox, the requirements for the rooms where they are installed are not strict. All Celtic models are approved by Rostekhnadzor.
Thanks to regular maintenance, the service life of the equipment is significantly extended. When the appropriate codes appear on the display, they clean the filter, check the draft, and eliminate other simple malfunctions. More complex repairs related to automation are performed only by service departments.

Device and principle of operation
Celtic gas heaters are used for heating apartments and private houses. If the building area is more than 400 m², the devices are turned on in a cascade scheme.
- Heat exchangers of the first circuit, for heating copper, the second, for domestic hot water - steel.
- The difference between the fans used is the possibility of changing the speed. They are located above the firebox and are working to improve boost conditions.
- Special pumps are used to prevent the formation of scale and rust.
- Water pressure should be at least 0.15 bar, gas - 0.01 bar.
- The built-in stabilizer ensures normal operation at a voltage of 150–290 V.
- Automation monitors all processes: prevents accidents, freezing, overheating, gas leak.
- The fuel supply is controlled by a microchip.
- The volume of heated water is equal to the amount required when opening the tap. Due to this, resources are saved.
- When operating, the heater makes a noise of 37 dB.
- For 72 hours, trouble-free operation in emergency mode is ensured.
- There is a remote control. The remote control is equipped with a self-monitoring function, so you can see the display of error codes.
Error Codes
- A1 - indicates interruptions in the interaction of the remote control and the main board. The solution is to check the connecting cables and pin connections.
- A2 - indicates a malfunction of the fan. The solution is to verify that the connection is correct. Check the voltage at the contacts.
- A3 - pump breakdown. Replace.
- A4 - the thermostat has overheated. The normal coolant circulation is disturbed. There is no air in the expansion tank. Correction of the situation - turning off, closing the taps and draining the water. Air injection up to 1 atm. Additionally, checking and cleaning the return filter is needed. After that, open the taps and start the boiler.
- A5 - lack of coolant. The pressure is raised to 1 atm. It is important to ensure that there is no leakage of coolant or leakage of the three-way valve.
- A6 - faulty gas supply system. Reasons: the voltage regulator does not work correctly or the gas filter and gearbox are clogged.
- A7 - gas valve is defective. The solution is to check the connection cables and the valve itself. You may need to replace the control unit.
What other malfunctions are there?
There are frequent situations when the temperature of the coolant "freezes" at 60 degrees. The most common cause is a clogged filter or gearbox. Because of this, the apparatus cannot “warm up” the water to the set value.
Another common mistake is speakers. When the device is turned on, noise starts. Possible causes of the malfunction:
- lack of air in the heating system;
- a foreign object on the pump blades;
- heat exchanger clogging;
- violation of the contact of the temperature sensor;
- cable breakage between the sensor and the control unit.
It happens that the noise starts when cold water is turned on, after which an error A5 is issued and the device is blocked. This saves him from failure. To correct the situation, it is enough to add water to the heating system.
Reviews
DS ESR-2.20 FFCD: Yuri T., Kostomuksha
Failures for three years of operation could not be found. Heated 3-room apartment 80 m2. Installed in the kitchen, takes up very little space - hangs on the wall. Convenient and intuitive controls, easy electric ignition. If pressure drops in the system, manual recharge is allowed. Not afraid of power surges - built-in stabilizer. Almost silent.
Celtic ESR-2.20: Polina D., Sanchursk
We live in a private house, we heat the house with gas. This boiler has been working with us for 4 years. At any moment, as soon as it seems cold, you can turn on the heating. I didn’t have to spend money on a column - it also heats hot water. And in sufficient quantities. It can be turned off altogether, if not needed. There is also a minus, without light, everything immediately disappears - both heat and hot water. We have to control the pressure inside the boiler, if it goes down, increase it, if it rises, turn off the device, give it a rest. It is also necessary to periodically change the filters.
Celtic boilers are real "mini boiler rooms". Occupying a minimum of space, they provide the house with heat and hot water and at the same time save the money of their owners. Featuring high performance, they are cheaper than European counterparts. Korean heaters are fuel efficient and easy to manage. This is one of the best offers in the domestic market of heating equipment.
