Radiant floor heating panels of a room with different locations is modeled by using CFD. All cases is simulate by employing k-ε equation turbulence model. After validation of code, average room air temperature, vertical air temperature difference and velocity of room air are used to predict the thermal comfort conditions in the occupied zone. Effect of indoor room air temperature and radiant floor heating panel locations on thermal conditions in occupied zone is studied. The results present that both the indoor room air temperature and radiant floor heating panels locations have effect on thermal comfort conditions and at low indoor temperature the radiant floor heating panel is insufficient to achieve thermal comfort conditions but can be reduced heating load.
