Distribution manifolds for room heating systems are used to optimally distribute the heating fluid in ondol(Korean underfloor heating system) circuits for each room heating separately in a house whose heating systems are district , central or individual heating systems. Recently, the energy saving is one of hot issues in industrial and engineering fields, so distribution manifolds for room heating systems are developed to improve the heating efficiency and save heating cost. In this study, Items and methods of distribution manifolds for performance evaluation of room heating systems are researched. For performance evaluations, flow rate distribution accuracy test, hydraulic characteristics per flow rate control valve`s indicator and noise tests are researched.
