Disclosed is an exhaust heat recovery apparatus applied to agricultural heating devices. The heating device according to the present invention comprises: a main body in which a combustion flue is formed inside thereof, a burner is mounted to one portion of the outside thereof, a heated air outlet is formed on a lower portion thereof, and a supply fan is formed on an upper portion thereof and an exhaust pipe which is mounted to one portion of the main body to be communicated with the flue, and discharges exhaust gas. The exhaust heat recovery apparatus applied to agricultural heating devices according to the present invention comprises: a casing which is formed on an upper portion of the main body, and in which the exhaust pipe is connected to one side thereof, and a final communication pipe, which discharges gas in which exhaust heat is recovered, is formed on the other side thereof a steam supply fan which is coupled to the upper portion of the casing, and transfers the outdoor air to the main body after suctioning the outdoor air into the casing and a heat exchange unit which is formed inside the casing, and heat exchanges the outdoor air by heating the outdoor air, which is introduced from the steam supply fan, and used to be the exhaust gas introduced from the exhaust pipe, transferred, and introduced to the steam supply fan. Accordingly, the exhaust heat recovery apparatus of the present invention recycles exhaust heat by recovering the exhaust gas from a heating device, thereby: reducing waste of energy has more efficient heat exchange and performs a stable heat exchange function which can be easily manufactured at low costs.COPYRIGHT KIPO 2016농업용 난방기기에 적용되는 배기열 회수장치 가 개시된다. 본 발명에 따른 농업용 난방기기에 적용되는 배기열 회수장치 는, 내부에 연소용 노통이 형성되고, 외부 일측에 버너가 장착되며, 하부에는 온풍 토출구가 형성되고, 상부에는 급기휀이 형성된 본체 상기 노통에 통하도록 본체의 일측에 장착되어 배기가스를 배출하는 배기연통을 포함하는 난방기기에 있어서, 상기 본체의 상부에 형성되며 일측에는 상기 배기연통이 연결되고, 타측에는 배기열이 회수된 가스를 배출하는 최종연통이 형성된 케이싱 상기 케이싱의 상부에 결합되어 외기를 케이싱 내로 흡입한 후 본체로 송기시키는 송기휀 상기 케
