Advantages of Ondol

-The latest global trend in Heating System is 'Ondol,' which is Korean traditional Floor heating..
-‘Ondol’ is underfloor heating which uses radiant heat transferred from the passageways for heat and smoke beneath the floors to directly convey the warmth to human bodies.
-The underfloor heating keeps it warm in the lower layers of air and relatively cool in the upper layers of air so that it makes people in the room feel much more comfortable and pleasant in comparison to the air circulation heating.
-Ondol does good to the respiratory organs and skins as it does not cause asthma and also prevents skin from being dried.
-It is more efficient in warming up the entire indoor as the warm air in the lower layers of air is lighter than the cold air enough to move up to the upper layer of air. 'Ondol' is therefore the most optimal heating system not just by making people feel comfortable and pleasant but also by being so effective in heating indoors.
