Korea's unique underfloor heating system called "ondol" will likely be designated as one of the country's intangible cultural assets. 

The Cultural Heritage Administration on Friday issued a notice on the possible designation.

Ondol, an underfloor heating that uses direct heat transfer from wood smoke to heat the underside of a thick masonry floor, is a two-thousand year old Korean traditional housing culture. 

The administration will make a final decision on the designation after a month long deliberation by the intangible cultural asset committee.
