Overview of Celtic gas boilers

The Celtic gas boiler is a product of a South Korean giant that produces a variety of household appliances. Celtic heaters incorporate the company’s own innovations to improve performance and efficiency. Korean wall-mounted boilers are universal – they are suitable for both small housing constructions with an area of ​​​​100-150 square meters. m, and for cottages up to 400 sq. 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 manufacturer in South Korea. The priority direction in the field of gas heaters is the production of wall-mounted double-circuit boilers.

Features of mounted boilers Celtic

The double-circuit hinged device “Celtic” is stuffed with all sorts of automation. The Koreans did not stint on innovative developments and automation of all processes occurring during the operation of gas equipment. Automation controls breakdowns (there is a self-diagnosis system), ignition, flame intensity, pressure – there is no need for a person to interfere in the operation of “smart” equipment.

Combustion chamber device

All Celtic wall-mounted boilers have a closed firebox. Modular forced draft burner installed. Air is blown by a fan from the street. Similarly, with the help of a fan, exhaust gases are removed. 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 heat carrier and water in the hot water supply are heated separately, each circuit has its own temperature. This approach allows you to increase the heating rate and energy efficiency of the device. Hot water settings are set via the controller. 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 water intake points.

Security questions

The security 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 discharging excess coolant. Condensing models also provide control over the drop in gas pressure and overheating. There is frost protection.

condensation module

All premium versions are equipped with a condensing module. The energy of the exhaust gases is stored and used to heat the coolant. Due to the additional energy, the efficiency increases, in such devices it reaches 105%.

Continuity

Innovative technologies make it possible to create ultra-reliable equipment. At first, Celtic boilers function practically without failures and breakdowns. But only with proper installation, configuration and timely maintenance. Platinum models are equipped with an alternator that protects all volatile components from power surges. When the light is turned off, the equipment settings will be saved. When the machine is turned on, the mode set just before turning it off will be started.

Self-diagnosis

Malfunctions detected by the self-diagnosis system are displayed on the display in the form of codes. To decrypt them, you need instructions – it contains a list of possible error codes and their decoding. This simplifies the detection of breakdowns and maintenance of equipment.

Installation

When installing Celtic gas equipment, you need to remember:

• All models are volatile, they require electricity.
• The piping is carried out as standard: heating and hot water pipes are connected to the device. A water treatment system is installed for make-up.
• Permission is granted for installation. Since the boilers use a closed furnace, the requirements for the premises where they are installed are not strict. All Celtic models have an operating permit from Rostekhnadzor.

Due to regular maintenance, the service life of the equipment is significantly extended. When the corresponding 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.

The device and the 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 switched on in a cascade scheme.

• Heat exchangers of the primary circuit, copper for heating, the second, for hot water – steel.
• The difference between the fans used is the ability to change the speed. They are located above the firebox and work to improve pressurization conditions.
• Special pumps are used to prevent the formation of scale and rust.
• Water pressure must be at least 0,15 bar, gas – 0,01 bar.
• The built-in stabilizer ensures normal operation at a mains voltage of 150–290 V.
• All processes are monitored by automation: it prevents accidents, freezing, overheating, gas leakage.
• The fuel supply is controlled by a microchip.
• The volume of heated water is equal to the amount required when the tap is opened. This saves resources.
• When operating, the heater emits noise at a level of 37 dB.
• Uninterrupted operation in emergency mode is ensured for 72 hours.
• 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 the connection of the contacts.
• A2 – indicates a fan malfunction. The solution is to check if the connection is correct. Checking the voltage on the contacts.
• A3 – pump failure. Replace.
• A4 – the thermostat has overheated. The normal circulation of the coolant is disturbed. There is no air in the expansion tank. Correcting the situation – turning off, closing the taps and draining the water. Air pumping up to 1 atm. Additionally, you need to check and clean the return filter. After that, the taps are opened and the boiler is started.
• A5 – lack of coolant. The pressure is raised to 1 atm. It is important to make sure that there is no leakage of the coolant and leakage of the three-way valve.
• A6 – the gas supply system is faulty. Causes: the voltage stabilizer does not work correctly or the gas filter and gearbox are clogged.
• A7 – the gas valve is faulty. The solution is to check the connecting cables and the valve itself. The control unit may need to be replaced.

What other problems 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 reducer. Because of this, the device cannot “warm up” the water to the set value.

Another common mistake is AC. When the device is turned on, the noise starts. Possible causes of the malfunction:

• lack of air in the heating system;
• foreign object on the pump blades;
• clogging of the heat exchanger;
• violation of the temperature sensor contact;
• broken cable between the sensor and the control unit.

It happens that the noise starts when cold water is turned on, after which error A5 is issued and the device is blocked. This saves him from failure. To remedy the situation, it is enough to add water to the heating system.

Reviews

DS ESR-2.20 FFCD: Yuri T., Kostomuksha

No defects were found during the three years of operation. I heat a 3-room apartment 80 m². Installed in the kitchen, takes up very little space – hanging on the wall. Convenient and clear control, easy electric ignition. If the pressure drops in the system, manual replenishment is allowed. Not afraid of power surges – built-in stabilizer. Virtually silent.

Celtic ESR-2.20: Polina D., Sanchursk

We live in a private house, we heat the house with gas. This boiler has worked for us for 4 years. At any time, 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 quantity. 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 drops, increase it, if it rises, turn off the device, give it a rest. You also need to change the filters periodically.

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 money for their owners. Featuring high performance, they are cheaper than European counterparts. Korean heaters are fuel efficient and easy to operate. This is one of the best offers in the domestic market of heating equipment.
