    Patent number: 4861435
    Abstract: A water distillation apparatus having a distilled water storage tank and a water boiling tank. Components associated with the boiling tank control the level of water therein and production of steam from the water contained therein. A steam flow line permits steam flow from the boiling tank into the storage tank. A distilled water cooling coil disposed in the storage tank at a lower region below the distilled water level is connected with a cool water infeed flow line. A steam condensing coil disposed in the storage tank at an upper region thereof above the desired water level and the cooling coil is connected with the cooling coil. Steam which enters the storage tank can directly contact the condensing coil exterior surface for causing the steam to condense into distilled water in the storage tank.
