Underfloor heating system is more suitable for space heating because of its unique temperature gradient profile. If solar radiation can be utilized for heating of water in radiant floor heating system, the cost of electricity can be reduced. Because of the sufficient availability of solar radiation in Kathmandu Valley during winter season, underfloor heating with solar water heating can be a viable technology for residential buildings. So this paper is focused on identifying suitable system/or domestic radiant floor heating system. Compound parabolic concentrator (CPC) water heating system is more suitable for heating water because tracking system is not required and sufficient water temperature can be achieved. It is also found that more studies are necessary to make the system cost effective and suitable for the residential buildings in Kathmandu.
