NCB 350
A manager for gas charges in our home
World’s best heat efficiency of 98.8%
KD Navien’s green technology takes care of people and nature for a better future.
Unlike regular boilers, the condensing boiler is a high-efficiency and high-tech boiler that does not discharge heat from primary combustion.
Instead, it recycles the heat, using it once more.
Saving gas charges by 28.4% at maximum
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.
Boiler with much less noise
It reduces noise by 11% compared to existing boilers by using multi-layered soundproof design that absorbs noise.
Even the elderly can easily use this by using the room control's voice guidance
The boiler adds sophistication to your living space with its refined design and color.
The design even accounts for the air flow
for stable and optimal combustion
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
- KD Navien's condensing technology leads condensing history in Korea with its first development in Asia!
- Slim-type boiler technology reduces the length of flame
- Eco-friendly power combustion system with NOx emissions reduced by 25% compared to existing boilers
- Combustion is vastly improved by controlling the amount of blast based on the optimal combustion condition.
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.
This new ASA heating system reduces temperature fluctuations and automatically adjusts the heating level.
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 uses Navien’s technology and knowhow to swiftly supply hot water. It maintains a constant amount of hot water at a certain temperature, even when hot water is used simultaneously in several places.
-30 - 60℃ at 1℃ intervals
Every detail is handled for your family's happiness and safety!
-
Korea’s only APS (Air Pressure Sensor) is safe, even when there's heavy wind.Combustion is ensured, even in heavy wind as fast as 55m a second! The boiler can be safely used in a high-rise apartment, residential building, or waterfront with heavy wind without worrying about headwind.
-
State-of-the-art digital gas & air proportional controlPrecise digital combustion method! Optimal combustion is realized by controlling the amount of gas and air with an advanced digital method.
-
Dual CPU for dual detectionThe Double Safety System uses 2 CPUs to monitor the boiler 24 hours a day.
-
Smart freeze prevention systemThe design effectively prevents the freezing of hot water pipes.
-
Part failure notificationsA/S can be swiftly provided in response to part failure notifications.
The elderly can easily use the boiler with voice guidance. The thermostat also talks back and features volume control.
- Selecting LCD lamp for each function
- Larger font is easy to read for elderly users
- Ability to check boiler operation time on a cycle of several hours
