PURPOSE: A fluid heating device using solar energy is provided to enhance energy efficiency by collecting or reflecting solar energy even if a special device to increase energy efficiency is not additionally installed. CONSTITUTION: A fluid heating device(10) using solar energy comprises a water tank, a lift unit(200), and a control unit. A closed space is formed in the water tank to store fluid. The water tank comprises an inlet and an outlet to supply and discharge fluid. The water tank is formed from a photo-permeable or heat conductive material. The lift unit is vertically installed on both sides of an indoor window. The lift unit lifts the water tank so that the fluid is heated with sunlight and solar heat incident through the window. The control unit controls the operation of the lift unit. The hot water in the water tank is used as domestic water.
