Abstract: A heater tank for a heat pump system having a structure in which a capacity of a storage space may be changed as hot fluid is discharged. For example, the heater tank may include a main body having an internal space and one open side, and a capacity changing member that forms a storage space, in which a hot fluid, such as water may be stored, by closing the one open side in the internal space of the main body, and being moved so that a capacity of the storage space may be changed as the hot fluid is discharged.
