PURPOSE:To heat the entire part of a bathroom and to prevent dew condensed water from dropping from the ceiling by causing hot water to flow in a wide range from the ceiling through a wall to the floor. CONSTITUTION:Hot water obtained from a solar hot water heater 5 or the like is caused to flow to a ceiling heating water heater 1 provided in a widely spread state in the ceiling thereby to perform space heating by a radiation heat from a ceiling surface 6. Hot water flowing along a ceiling heating water heater 1 flows along a wall heating hot water path 2 provided in a spread state at the inner part of the wall of the bathroom, and space heating due to the radiation heat from a wall surface 7 is possible. Further, hot water is discharged to the floor surface 4 of the bathroom via a floor surface hot water discharge port 3 positioned at the lower end of the wall heating hot water path 2 and provided at the highest position of the floor surface gradient thereby to warm the floor surface 4. Thus, the entire part of the bathroom can be simultaneously heated. Further, by the heating of the ceiling surface it is possible to prevent dew condensed water from dropping from the ceiling.
