Ondol is a traditional heating system in Korea. After new building type, apartment was introduced from western world around 1960, there have been dynamic changes in heating system in apartment. At first, designers supposed that apartment should match to the stand-up-living-style and the radiator system regardless traditional life style. Dwellers, however, didn't accept such a heating system even though the increase of the use of standing type furnitures such as bed, sofa, table, sink etc. Nowadays, Ondol is facilitated to the entire of the home even to the living room and dining/kitchen which radiator system was supposed to be accepted by designers. This try and error process shows that heating system is not only the physical facility itself, but also the cultural element reflecting the properties of way of life. And also it prove that one culture can not substitute the other culture, but merely conflict, mediated each other.
