<p>PROBLEM TO BE SOLVED: To improve energy efficiency during hot water supply operation or cool storage operation, resulting in reduction of a running cost, in a hot water supply device to store hot water, having different temperatures, in a stratified state in a hot water storage tank. SOLUTION: A hot water supply device comprises a hot water storage tank 1, and a heat pump system 16 to regulate the temperature of hot water in a hot water storage tank 1. A first water supply port 19 is formed in the intermediate part of the hot water storage tank 1, a hot water inflow port 3 is formed on the upper end side, and a cold water inflow port 4 is formed on the lower end side. A first baffle 27 to exert an up flow component on inflow hot water is arranged at the hot water inflow port 3, a second baffle 28 to exert a down flow component on inflow cold water is arranged at the cold water inflow port 4, and a third baffle 29 to exert an up flow component on inflow supply water is arranged at the first water supply port 19.</p> |
