Uses natural convection law itself to form an invisible thermal barrier inside one connected water body, greatly reducing downward heat transfer and enabling localized high-temperature vapor generation.
The same solar energy is reused twice: first for vapor generation and again through internal condensation heat recovery for hot water heating.
Solar heating, vapor generation, vapor transfer, condensation, heat recovery, distilled water production, and hot-water storage are integrated within one connected water body through coordinated passive thermodynamic behavior.
Solar BiWater concentrates solar energy within evacuated glass tubes instead of continuously dispersing heat into a large bulk water mass, enabling faster and more efficient vapor generation.
Dedicated internal conduits collect and transfer vapor directly from the highest-temperature region without external vapor piping, pumps, valves, or complicated vapor collection structures.
Uses atmospheric pressure balance, gravity, and hydrostatic connection to naturally stabilize internal water levels without active pressure-control systems.
Moving vapor inside the conduits transfers heat into surrounding water, promoting additional localized vapor generation and improving thermal utilization efficiency.
Most thermal processes occur inside only evacuated glass vacuum tubes and a polyurethane-insulated water tank, greatly reducing heat loss and mechanical complexity.
Integrated solar thermal technology for simultaneous distilled water production and water heating with high energy efficiency, reduced maintenance, and long service life.
Solar Distillation Water Heaters combine solar water heating and advanced solar water purification in one integrated thermal energy system, delivering both hot water and distilled water simultaneously unlike conventional solar water heaters that only provide hot water.
Unlike conventional water purifiers that depend heavily on plastic filters, cartridges, and internal components, Solar Distillation Water Heaters primarily utilize glass, stainless steel, and copper piping for cleaner and safer water production.
Solar Distillation Water Heaters purify water through high-temperature evaporation and condensation, a phase-change purification process where only pure vapor rises and condenses while many contaminants, salts, particles, bacteria, and viruses remain separated.
Unlike conventional water purifiers that consume electricity and require expensive filters, membranes, replacements, and regular maintenance, Solar Distillation Water Heaters use solar-powered vaporization and condensation to produce pure water with minimal operating costs and reduced consumable waste.
Solar Distillation Water Heaters naturally support daily self-cleaning through repeated heating, vaporization, condensation, and hot water circulation, helping reduce contaminant accumulation commonly found inside conventional filter-based purification systems.
Daily distilled water production naturally varies with sunlight intensity, allowing users to directly observe system operation and purified water output in real time while making abnormal water flow or leakage easier to detect.
Solar Distillation Water Heaters efficiently utilize solar energy twice: first to generate vapor inside vacuum glass tubes, and then to recover the released condensation heat to warm water in the storage tank, resulting in exceptionally high solar energy utilization efficiency.
Solar Distillation Water Heaters primarily utilize durable glass and stainless steel materials while operating with minimal moving parts, reducing dependency on pumps, motors, sensors, and replaceable plastic components, resulting in exceptionally long service life and lower maintenance requirements.

We specialize in the design and manufacturing of advanced solar thermal products, with strong expertise in pre-heat exchanging solar water heaters for residential, commercial, and industrial applications. We are also the developer of Solar BiAGUA solar distillation water heaters with multi-country patents, which will also be applied to solar desalination. Our vision is: “Wherever there is sunlight and sea water, there will be sufficient clean water.”
