PROBLEM TO BE SOLVED: To reduce the manufacturing cost by improving the productivity of a louver attached to a warm air blowout port of a warm air heater. SOLUTION: An air distribution passage 5 communicating a front part and a rear part of a frame body 1 is formed, an indoor convection fan 6 is mounted at a back face side of the frame body, the warm air blowout port 7 is formed at a front face side of the fame body, and the indoor air blown to the air distribution passage 5 by the indoor convection fan 6 exchanges the heat with a combustion chamber 3 and a heat exchanging part 4, and is blown out from the warm air blowout port 7 as the air of high temperature. A front base A and a rear base B are longitudinally arranged at a specific interval on the warm air blowout port 7, and a louver 8 is constituted by a front louver 8a and a rear louver 8b respectively mounted on the front base A and the rear base B. As the front louver A and the rear louver 8b are respectively constituted by a number of cut and raised pieces formed on the front base A and the rear base B, the number of components and the number of assembling processes can be reduced and the productivity can be improved. Further as the front louver 8a and the rear louver 8b are longitudinally arranged, the rear louver 8b is positioned at a depth of an opening 9 of the front base A, and the inside of the air distribution passage 5 can not be directly seen.
