Solar Distillation Water Heater => Solar Water Heater + Solar Water Purifier
SOLAR ENERGY => DISTILLED WATER + HOT WATER
The Solar Distillation Water Heater integrates solar heat collection, steam generation, steam transport, distilled water production through condensation, and condensation heat recovery for heating domestic water. It uses the same solar energy to produce high-purity distilled water while simultaneously heating domestic water, making it both an efficient solar water heater and a superior solar water purification system.
Benefits
BiAGUA overcomes the limitations of conventional solar water heaters and electrical water purifiers, operating entirely at atmospheric pressure to efficiently produce distilled water and domestic hot water at the same time.
Hot water for the home
Recovered condensation heat helps warm domestic water for bathing, washing and cleaning.
Long-term savings
Solar heat supplies both outputs, reducing dependence on purchased water and conventional water-heating energy.
Environmentally friendly
A passive solar process reduces energy demand and disposable purification consumables.
A greater use of solar heat
Evacuated glass tubes capture sunlight and generate vapor. Stainless-steel conduits guide the vapor down to a condenser inside the insulated water tank. As distilled water forms, condensation heat is recovered to warm the surrounding domestic water. The two products leave through separate outlets.
Excellence is born from simplicity
Operating at atmospheric pressure, BiAGUA uses natural solar heating, evaporation and condensation. Its distillation process needs no electricity, filter cartridge, RO membrane, pump or anti-scaling chemical. Producing high-purity water at home can become more accessible and affordable; actual output and savings depend on local conditions.
How Solar Distillation Water Heater Works
ONE SOLAR SYSTEM · TWO USEFUL PRODUCTS
Sunlight heats the water inside evacuated glass tubes. Vapor travels through stainless-steel conduits to an internal condenser, where distilled water forms and condensation heat helps warm domestic water.
Follow the sunlight
Collect solar heat
Sunlight heats water in the evacuated glass tubes.
Generate vapor
Water evaporates; vapor gathers above the water level.
Guide vapor downward
Stainless-steel conduits carry vapor to the condenser.
Condense and recover heat
Vapor forms distilled water as its released heat warms the tank.
Use both products
Collect distilled water and draw domestic hot water from separate outlets.
Models and Performance
SIX MODELS · ONE SOLAR IDEA
Compare six tube configurations and indicative daily production. Output depends on sunlight, climate, inlet-water temperature and operating conditions.
Six solar distillation models
| Model | Tubes | Distilled water L/day | Hot water L/day | CO₂ avoided kg/year* |
|---|---|---|---|---|
| SD-12/1800-6/120 | 12 | 4–8 | 120 | 591 |
| SD-15/1800-7.5/150 | 15 | 5–10 | 150 | 739 |
| SD-18/1800-9/180 | 18 | 6–12 | 180 | 887 |
| SD-20/1800-10/200 | 20 | 7–13 | 200 | 986 |
| SD-24/1800-12/240 | 24 | 8–16 | 240 | 1,183 |
| SD-30/1800-15/300 | 30 | 10–20 | 300 | 1,478 |
*Results depend on solar radiation, climate, inlet-water temperature, location and operating conditions.

Global reference prices for packaged drinking water and hot water
| Market | 19 L bottled water | Value of 3,000 L/year | 60,000 L hot-water value / year | Total value / year |
|---|---|---|---|---|
| United States | USD $6–10 | USD $950–1,580 | ≈ USD $330 | USD $1,280–1,910 |
| Europe | USD $9–18 | USD $1,420–2,840 | ≈ USD $495 | USD $1,915–3,335 |
| Middle East | USD $2.70–4.00 | USD $430–630 | ≈ USD $155 | USD $585–785 |
| South Asia | USD $1.20–2.50 | USD $190–400 | ≈ USD $155 | USD $345–555 |
| Africa | USD $1.50–6.00 | USD $240–950 | ≈ USD $270 | USD $510–1,220 |
| South America | USD $3.50–9.00 | USD $550–1,420 | ≈ USD $350 | USD $900–1,770 |
Hot-water values assume 60,000 L/year heated from 20°C to 45°C at 90% efficiency. The total adds the value of 3,000 L/year of distilled water, estimated using 19 L bottled-water reference prices, to that market's hot-water estimate.

The advantages of Solar Distillation Water Heater
EXCELLENCE IS BORN IN SIMPLICITY
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.
Five practical advantages
Use solar heat twice
Solar heat first generates vapor; condensation heat then contributes to warming domestic water.
High-purity distilled water
Vapor condensation separates many dissolved salts and non-volatile substances from water. Test output before claiming drinking-water suitability.
Fewer replaceable consumables
The distillation process has no filter cartridge, RO membrane or anti-scaling chemical to replace.
Passive and durable
Atmospheric-pressure operation and a vapor path without an external pump support simpler maintenance.
Reduce microplastic risk
Glass tubes, stainless-steel vapor conduits and a stainless-steel condenser minimize plastic contact in the principal water-production path.
