The heated air pipe 50 is stacked and stacked inside the preheated heater body 22 in order to increase the surface area exposed by the exhaust gas, and the heated external air is passed through the burner air pipe 54 to the burner fan 14. It flows into the burner 12 by).

이상에서 살펴본 바와 같이 본 발명에 의한 예열히터를 구비한 열매체보일러는, 배기가스의 폐열을 사용하여 외부공기를 가열함으로써 버너로 유입되는 공기의 온도를 높일 수 있다. 이로 인해 상온의 공기가 본체내부로 유입됨에 의해 발생되는 열손실을 줄여줌으로써 열매체보일러의 열효율을 높이는 장점이 있다.As described above, the heat medium boiler having the preheater according to the present invention can increase the temperature of the air flowing into the burner by heating the outside air using the waste heat of the exhaust gas. Therefore, there is an advantage of increasing the thermal efficiency of the heat medium boiler by reducing the heat loss caused by the air at room temperature flows into the body.
