PROBLEM TO BE SOLVED: To realize a technique wherein the height of a gas warm air heater is reduced, while fully mixing combustion gas and air. SOLUTION: A combustion case 30 is accommodated at a rear position in a body case 22, and includes therein a gas burner 36 and a combustion gas exhaust outlet 30b in the upper portion. A fan 46 is accommodated in the body case 22 in front of the combustion case 30 and at a height where it overlaps on the combustion case 30, and communicates with a warm air blow-off outlet 48 and is higher than the combustion case 30 in its height. A mixing space 52 is located rearward of a front plate of the body case 22, in frontal of the front plate of the combustion case 30, and at an upper portion of the fan 46, where air sucked from the air suction inlet 27 and combustion gas exhausted from the combustion gas exhaust outlet 30b are mixed.
