PURPOSE: A hot-water circulation-type stone bed heating plate is provided to secure safety by removing worry of electromagnetic waves while reducing a power consumption ratio. CONSTITUTION: In a hot-water circulation-type stone bed heating plate(1), the bottom surface and each edge side are formed as an aluminum frame and the upper side is open. The inside of the stone bed heating plate is filled with a urethane foam(2). A hot-water pipe(3) is arranged in the stone bed heating plate before filling the inside of the stone bed heating plate with the urethane foam. Water supply and drain pipes(4) of the hot-water pipe are connected to a hot-water heating circulation pump(5) separately installed to the outside and the bed heating plate is heated while hot-water is circulated.
