Use solar heat twice
Solar heat first generates vapor; condensation heat then contributes to warming domestic water.
One passive solar technology supports household hot water and produces distilled water. Explore the design choices behind efficiency, simpler maintenance and a lower-plastic-contact water path.
Solar heat first generates vapor; condensation heat then contributes to warming domestic water.
Vapor condensation separates many dissolved salts and non-volatile substances from water. Test output before claiming drinking-water suitability.
The distillation process has no filter cartridge, RO membrane or anti-scaling chemical to replace.
Atmospheric-pressure operation and a vapor path without an external pump support simpler maintenance.
Glass tubes, stainless-steel vapor conduits and a stainless-steel condenser minimize plastic contact in the principal water-production path.
