PURPOSE: A solar system for heating and supplying hot water is provided to reduce time and fuel for heating a heat storage tank and to supply hot water of uniform temperature by using a tank-in-tank type solar heat storage tank. CONSTITUTION: A solar system comprises a heat storage unit(1) for absorbing heat from a sun and a heat storage tank(2). The heat storage tank consists of an inner case and an outer case. The inner case is a hot water storage tank, and a thermal medium is filled in the space between the inner case and the outer case. The solar system heats the room by transferring the heat source stored in the heat storage tank and supplies hot water. As a part of the heat storage tank is heated according to the preparation of the inner case maximizing a heat transfer area, thermal efficiency is improved and fuel and time for heating are reduced.
