The constriction thermal resistance due to the floor supports in the Ondol floor heating system was investigated. The resistance has significant influence on the uniformity of floor surface temperature and heat flux through the floor. The heat flux decreased as much as $30\%$ for the geometry of the same channel and support areas.
