STORAGE TYPE HOT WATER SUPPLY DEVICE

To provide a storage type hot water supply device capable of reducing fluctuation in temperature of hot water flowing out from heating means, even in a case when a hot water supply operation to make the hot water heated by the heating means flow into mixing means without flowing into a hot water storage tank, and supply of the hot water from the mixing means is started or terminated in a hot water storage operation.SOLUTION: A storage type hot water supply device (1) executes a hot water storage operation, and a hot water supply operation for making hot water heated by heating means (31) flow into a hot water supply flow channel (8) and mixing means (61) without flowing into a hot water storage tank (2). Flow channel switching means (41) can switch a hot water storage heating passage and a hot water supply heating passage. The hot water storage heating passage is a passage formed from a lower portion of the hot water storage tank (2) to an upper portion of the hot water storage tank (2) through a pump (7) and the heating means (31) without passing through the hot water supply flow channel (8). The hot water supply heating passage is a passage formed form the lower portion of the hot water storage tank (2) to the hot water supply flow channel (8) through the pump (7) and the heating means (31) without passing through the hot water storage tank (2).SELECTED DRAWING: Figure 1 【課題】加熱手段により加熱された湯を貯湯槽に流入させることなく混合手段に流入させる出湯運転を実行可能で、貯湯運転のときに混合手段からの給湯が開始または終了した場合においても加熱手段から流出する湯の温度の変動を軽減できる貯湯式給湯装置を提供する。【解決手段】貯湯式給湯装置（１）は、貯湯運転と、加熱手段（３１）により加熱された湯を貯湯槽（２）に流入させることなく出湯流路（８）及び混合手段（６１）に流入させる出湯運転とを行う。流路切替手段（４１）は貯湯加熱経路と出湯加熱経路とを切り替え可能である。貯湯加熱経路は貯湯槽（２）の下部からポンプ（７）及び加熱手段（３１）を経由した後に出湯流路（８）を経由することなく貯湯槽（２）の上部に繋がる経路である。出湯加熱経路は貯湯槽（２）の下部からポンプ（７）及び加熱手段（３１）を経由した後に貯湯槽（２）を経由することなく出湯流路（８）に繋がる経路である。【選択図】図１
