PURPOSE: An automatic hot water circulation system is provided to automatically continuously hot water by utilizing pressure difference and the inertial force of water supply in heating water supply and collecting tanks. CONSTITUTION: An automatic hot water circulation system comprises a hot water supply tank(10), a hot water collection tank(30), and a pressure regulating chamber(40). When the inner pressures of the hot water supply tank and the hot water collection tank increase while a relief valve(50) is closed, a water supply pressure damping unit(15) reduces the water supply pressure within the hot water supply tank through a diaphragm. When the relief valve is opened and the internal pressure of the hot water collection tank is lowered to the atmospheric pressure, the maximum pressure difference between the hot water collection tank and the hot water supply tank is used as circulation power so that hot water of the hot water supply tank is provided through a heating water supply line(12). |
