A ventilation heating apparatus disposed on the ceiling of a room comprises a main body disposed outside the room, a ventilation air-blowing means disposed within the main body, a circulation air-blowing means disposed within the main body, a heat generating means disposed within the main body, and a louver covering the opening in the main body and disposed within the room. The main body is formed with an exhaust port and has a lower surface formed with an opening. The louver has a lower surface and a quadrangular frame. The lower surface of the louver is opposed to the opening in the main body. The frame of the louver projects from the outer periphery of the lower surface toward the main body so as to close the space between the lower surface of the louver and the ceiling. According to this ventilation heating system, the growth of fungus near the louver can be reduced.
