A modular water distillation apparatus includes a distillation unit which may be manually operated by adding water manually to the steam generator. The apparatus further includes an add-on holding tank and an add-on control unit which mounts to the holding tank and provides automatic control of the distillation unit by providing feedwater to the steam generator when the steam generator is deenergized and the holding tank is not full. The add-on control further includes a power receptacle for an add-on distilled water demand pump.

A water distillation apparatus comprising: a stand-alone distillation unit adapted to semi-manual operation in which operation of the distillation unit is initiated to produce distilled water in response to the manual addition of raw water thereto and is terminated in response to said raw water being substantially converted to distilled water, said distillation unit having a steam generator including a boiling tank, means for manually adding water to said boiling tank, water level monitoring means for monitoring the level of water in said boiling tank and energizing means responsive to said monitoring means for energizing said steam generator when the level of water in said boiling tank is above a first predetermined level and deenergizing said steam generator when said level is below said first predetermined level, said distillation unit further including condensing means connected with said steam generator for condensing steam produced by said steam generator into distilled water; a holding tank adapted to receive distilled water from said condensing means; and an add-on control selectively connectable with said stand-alone distillation unit for converting said stand-alone distillation unit to an automatically controlled distillation apparatus, said add-on control including: holding tank water level monitoring means for monitoring the level of water in said holding tank; feedwater valve means configured to be connected to said steam generator and a source of water and operative for admitting feedwater to said steam generator; and control means responsive to said energizing means and said holding tank water level monitoring means for operating said feedwater valve means only when said level of water in said holding tank is below a second predetermined level and said steam generator is not energized in order to automatically fill the boiling tank when the level of water therein drops below said first predetermined level provided that the level of water in said holding tank is not above said second predetermined level and to disable the distillation unit when the level of water in said holding tank is above said second predetermined level by withholding feedwater from the steam generator when the level in the holding tank is above said second predetermined level.
