Original Abstract Submitted

A hot-water supply apparatus is configured to perform a heat storage operation of storing heat of a heat medium and a hot-water supply operation of supplying hot water to a hot-water demand side through use of the heat of the heat medium. The hot-water supply apparatus includes a heat medium circuit through which the heat medium circulates, a latent heat storage device having a latent heat storage material, the latent heat storage device being configured to store heat and reject heat through transfer of heat between the latent heat storage material and the heat medium, a heat medium heat storage device in which the heat medium is stored so that thermal stratification is formed, and a heating device configured to heat the heat medium. The heating device heats at least the heat medium flowing out from a lower portion of the heat medium heat storage device.
