Most of the domestic buildings for residential purposes have used the radiant panel heating system, circulating hot water through the X-L pipe in the floor panel of the room. It was recently developed the radiant panel heating system using heat pipes with double wicks. Some experiments were carried out in this study to verify the thermal characteristics of this new heating method at the unit heating space that as heated by hot water from boiler through the coils installed in the floor heating panel, and which surrounded by outer space whose temperature of air be maintained constant. Flow rate, inlet and outlet temperatures of hot water and the heating time were yielded for various operating conditions and these results could be used for optimal design and efficient operation of the heating system as well as improvement of indoor air quality. We also found that the panel heating system with heat pipes was able to reduce the pumping power for hot water circulation by 4~31% compared with the conventional panel heating system using X-L pipe.
