PROBLEM TO BE SOLVED: To provide a hot water supply device capable of preventing hot water higher than a setting temperature from being tapped, when hot water supply is executed again after hot water supply is stopped in a hot water supply circuit.SOLUTION: A hot water supply device 1 includes a can body 10, a burner 11, a hot water supply circuit 2 and a bath after-burning circuit 3. A secondary heat exchanger 22 of the hot water supply circuit 2 is arranged above in a vertical direction with respect to a first primary heat exchanger 21. The bath after-burning circuit 3 has a second primary heat exchanger 32. A water inlet path 24 of the hot water supply circuit 2 is arranged between the secondary heat exchanger 22 and a bypass path 18, and has a curve part CP once extending downward in the vertical direction and extending upward.SELECTED DRAWING: Figure 1 【課題】給湯回路において給湯が停止された後に再度給湯が実行された際に設定温度よりも高温の湯水が出湯されることを抑制できる給湯装置を提供する。【解決手段】給湯装置１は、缶体１０と、バーナ１１と、給湯回路２と、風呂追焚回路３とを備えている。給湯回路２の二次熱交換器２２は、第１の一次熱交換器２１よりも鉛直方向において上方に配置されている。風呂追焚回路３は第２の一次熱交換器３２を有する。給湯回路２の入水路２４は、二次熱交換器２２とバイパス路１８との間に配置され、かつ鉛直方向において下方に延びてから上方に延びる湾曲部ＣＰを含む。【選択図】図１
