PROBLEM TO BE SOLVED: To provide a room-heating device that has high temperature increase effect of hot air for improving heat efficiency, and has less heat radiation for decreasing heat efficiency, and can be miniaturized. SOLUTION: A partition part 2 such as a wall, a ceiling panel, and a floor panel for partitioning the room 1 and its outside is provided with a hot-air supply opening 3 and a suction opening 4. At a position where the air supply opening 3 and the suction opening 4 are provided, a casing 5 is fitted to the outside of the room 1 of the partition part 2. A hot-air circulation path 6 is accommodated in the casing 5, where the path 6 sucks the air in the room 1 from the suction opening 4 and blows heated hot air into the room 1 from the air supply opening 3. A heating path 8 for heating with the combustion of a burner 7 arranged inside is allowed to be along the hot air circulation path 6 inside the casing 5 for heat-exchanging the combustion exhaust in the heating path 8 and air flowing in the hot air circulation path 6. An inlet 9 of the heating path 8 is connected to the outside of the room 1, and at the same time an exhaust vent 10 of the heating path 8 is connected to the outside. |
