A water purification system for use in combination with a domestic hot water heating tank. The system includes a water container for containing water separate from the water in the tank. A conduit carries hot water from the tank to the container, passing in close proximity to the heating unit of the hot water tank. A duct leading from the container conveys water vapor formed in the container to a receptacle. The water in the receptacle having been evaporated and condensed is thus purified for domestic use.
