     본 발명은 주택의 보편적인 난방 방식인 바닥 난방배관에 연결하여 공기를 직접 가열하여 주는 열교환 방열코일(6)과 가열된 공기를 실내로 공급해주는 휀(5), 온수공급과 휀을 제어하기 위한 제어장치(7)로 구성된다. 본 장치는 제어장치에 의해 공기난방기를 가동시키게 되면 휀(5)은 실내공기를 흡입하여 방열코일(6)로 공급하게 되고, 열교환 방열코일(6)은 바닥 온수배관으로부터 공급받은 고온의 온수를 순환시켜 방열핀에서의 열교환을 통해 가열된 난방공기를 토출부를 통해 실내로 공급하게 된다. 장비가 가동되는 동안 지속적인 열교환과 공기순환을 통하여 실내 공기온도는 신속하게 상승하게 되고, 제어장치를 통해 재실자가 설정한 온도에 맞춰 적정한 온도가 유지되도록 함으로써 쾌적한 실내 난방조건을 제공함은 물론 기존의 바닥 난방방식에 비해 높은 에너지 효율로 인하여 난방 비용 절감에도 기여할 수 있는 이점이 있다.
