Saving gas charges by 28.4% at maximum
The eco-friendly boiler minimizes carbon dioxide (greenhouse gas) and nitrogen oxide (pollutant) and saves energy resources by high heat efficiency. In addition to the reduction of fine dust, this boiler helps prevent the greenhouse effect by reducing CO2 by 479kg per year. This is equivalent to planting 208 pine trees.
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
Eco-premix burner
A smaller flame leads to reduced gas consumption and eco-friendly use.
- Burner system optimized for condensing
- Reduces gas consumption by precisely controlling the flame by 1/10
- Design enhances durability and low noise
The boiler can operate the pump at three different levels: high for more heating and low for less heating.
You can save electric charges by operating the boiler based on your needs.
The smart pump also reduces noise through quiet boiler operation.
You can reliably use the product for a long time without any failure, thanks to the pump's extended lifespan.
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.
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.
No temperature fluctuation in hot water temperature
