Radiant heating is a proven technology in space heating which offers many advantages to thermal comfort and energy conservation. For this reason, the usage of these systems is increasing from day to day and it has been widely investigated by the researchers. Different panel locations were examined experimentally with through the usage of a real size test chamber in accordance with pre-determined standards in this study. As a result of the research, it was become apparent that thermal comfort aspects in a room vary with the variation in placement configurations of the radiant panels. The goal was to estimate how thermal comfort is affected when varying inlet water temperatures are applied to different radiant wall heating panels' placement configurations. Vertical air temperature differences and mean radiant temperatures were investigated. Average vertical air temperatures of the locations 0.1 m and 1.7 m were found 0.14 degrees C, 1.11 degrees C and 0.73 degrees C respectively. The results confirm that the mounting radiant wall panels to different walls affect both thermal comfort and heating performance. Based on the experiments, the first case which is located on an exterior wall containing a window produces better results than the others.
