Zusammenfassung:	To provide a water heater capable of changing a hot water generation capacity easily at low cost, and improving heat efficiency.SOLUTION: A water heater WH comprises a combustor C and a heat exchanger HE. Among a plurality of straight tubular parts 60 constituting a heat transfer pipe 6B of the heat exchanger HE, a straight tubular part 60 located at one end in the side-by-side direction is a water inlet side straight tubular part 60a closest to a water inlet 62a. Some of a plurality of burners 1B of the combustor C is a non-combustion burner 1B' that does not cause drive combustion because fuel gas supply from a fuel gas supply head 4 is always stopped, and above the non-combustion burner 1B', the water inlet side straight tubular part 60a is located.SELECTED DRAWING: Figure 1 【課題】温水生成能力の変更を、容易かつ低コストで実現可能としつつ、熱効率を良好にすることも可能な温水装置を提供する。【解決手段】燃焼装置Ｃと、熱交換器ＨＥと、を備えている温水装置ＷＨであって、熱交換器ＨＥの伝熱管６Ｂを構成する複数の直状管体部６０のうち、横並び方向の一端に位置する直状管体部６０は、入水口６２ａに最も近い入水側直状管体部６０ａとされており、燃焼装置Ｃの複数のバーナ１Ｂの一部は、燃料ガス供給ヘッド４からの燃料ガス供給が常時停止されていることにより、駆動燃焼を生じない非燃焼バーナ１B'とされ、この非燃焼バーナ１B'の上方に、入水側直状管体部６０ａが位置している。【選択図】図１
