Abstract

A water distiller is provided which is used in conjunction with a hot water heater where normally wasted energy is used to preheat the hot water heater inlet. The distiller includes a heat storage tank, an evaporator tank having a water inlet, a heater and a steam outlet, and a first and second heat exchanger located within the heat storage tank. Steam generated in the evaporator tank passes through the first heat exchanger and condenses, forming distilled water. The heat rejected during condensation is absorbed within the heat storage tank. The second heat exchanger is used to preheat the water flowing to the hot water heater inlet by passing the water through the second heat exchanger on an as needed basis where it absorbs heat from the heat storage tank.
