PURPOSE: A hot water circulation device using vapor pressure is provided to continuously circulate a proper quantity of hot water by discharging hot water from a discharge tank to a hot water pipe at uniform pressure. CONSTITUTION: A hot water circulation device using vapor pressure comprises a water tank(20), a first valve, a second valve(50), a pressure tank(40), a heating tank(60), a pipeline(52), a discharge tank(80), and a pressure maintaining unit(82). Hot water is drawn into the water tank through an inlet port(24). The first and the second valve control the flow direction of water. The pressure tank transfers heated water through an outlet port(42) to the hot water pipe. The heating tank heats the water drawn in through the second valve. The pipeline delivers the hot water heated in the heating tank to the pressure tank. The discharge tank is formed in one side of the pressure tank and connected to the outlet port. The pressure maintaining unit discharges hot water to the hot water pipe while keeping uniform pressure. |
