A water distiller works by boiling water into water vapour, condensing it and then returning it to its liquid state. It is collected in a storage container.
Water distillers are neither intended to treat water that is visually contaminated nor intended to convert waste water to safe, microbiologically.
The process occurs in several steps:
- Municipal or well water is manually or automatically fed into the distiller unit’s boiling chamber.
- A heating element in the boiling chamber heats the water until it boils.
- The steam rises from the boiling chamber. Volatile contaminants (gases) are discharged through a built-in vent.
- Minerals and salts are retained in the boiling chamber as hard deposits or scale.
- The steam enters a coiled tube (condenser), which is cooled by cool water.
- Water droplets form as condensation occurs.
- The distilled water is collected in a storage tank. If the unit is an automatic model, it is set to operate to fill the storage tank.
