To realize efficient heat exchange through ultimate recovery of heat from combustion exhaust to a heat medium used for heating water.SOLUTION: A heat exchanger can increase the efficiency of heat exchange between combustion exhaust and a heat medium, etc. by comprising: a first housing section (second housing section 28-2) which stores a first heat exchange section (6-1) performing heat exchange between combustion exhaust (EG) and a heat medium; a second housing section (third housing section 28-3) which stores a second heat exchanger (6-2) performing the heat exchange between the combustion exhaust flowing from the first housing section and the heat medium and a third heat exchanger (6-3) performing the heat exchange between the combustion exhaust and water supply; an inclined plate (50) installed between the first housing section and the second housing section; a ventilation window section (56) which is installed on the inclined plate and introduces the combustion exhaust into the second housing section; and a shielding plate (58) which is extended from the inclined plate to the ventilation window section.SELECTED DRAWING: Figure 4 【課題】 燃焼排気から暖房水などに用いられる熱媒への究極的な熱回収を図り、効率的な熱交換を実現する。【解決手段】 燃焼排気（ＥＧ）と熱媒を熱交換させる第一熱交換部（６−１）を収納する第１の筐体部（第２筐体部２８−２）と、第１の筐体部から流入する燃焼排気と熱媒を熱交換する第二熱交換部（６−２）および燃焼排気と給水を熱交換する第三熱交換部（６−３）を収納する第２の筐体部（第三筐体部２８−３）と、第１の筐体部と第２の筐体部との間に設けられた傾斜板（５０）と、この傾斜板に形成されて燃焼排気を第２の筐体部の内部に導く通気窓部（５６）と、傾斜板から通気窓部に張り出して設けられた遮蔽板（５８）を備えることにより、燃焼排気からの熱媒などへの熱交換効率を高めている。【選択図】 図４
