Unlike regular boilers, the condensing boiler is a high-tech boiler that recycles its discharged heat. Heat exhausted from primary combustion is used once more, resulting in higher efficiency.


Saving gas charges by 28.4% at maximum
Saving gas charges by up to 28.4%
With the 1st grade of energy consumption efficiency rating system, this condensing boiler has high heat efficiency, which saves gas charges by up to 28.4% compared to regular boilers.
The condensing boiler not only helps to reduce fine dust by lowering nitrogen oxide emissions, but also restrains the greenhouse effect by reducing CO2 by 479kg per year. This amount of CO2 reduction is equivalent to planting 208 pine trees.

The product supplies the best level of hot water with its multi-temperature sensing technology, flow control technology, and precise flame control technology.
Thanks to the swift supply of hot water, the amount of water removed is small, which makes the product economical. In addition to maintaining a certain level of hot water, the product maintains the constant temperature and amount of hot water, even when hot water is used in several places at the same time.

The fine temperature control solves the problem of temperature fluctuation.
ASA control uses new technology to control the size of the flame and heating speed for each housing environment and temperature change based on multi-sensors.


Save more on gas charges!
Dual sensing control is the secret behind comfortable floor-type heating.
As the temperature of water after heating a room is checked once more, this product not only realizes more comfortable heating than existing boilers, but also saves more gas charges.
The product adopts a high-quality integral stainless heat exchanger.
- Lifespan is 3.8 - 4.5 times longer than other heat exchangers, thanks to its resistance to corrosion and erosion.
- Most advanced stainless heat exchange technology in Korea
