How to make a Solar Water Geyser at Home ???

You Will Need :

•  2L plastic bottles (60),
• Cartons (50)
• 100mm PVC pipe (70 cm)
• 20mm PVC pipe (11.7m)
• 90-degree 20 mm PVC elbows (4)
• 20mm PVC T-connectors (20)
• 20 mm PVC end caps (2)
• PVC glue
• Black matt paint
• Paint Roller
• Sand paper
• Self-amalgamating tape
• Tools – Rubber hammer, saw, wood or other material for the support

Process :

Use the 100mm PVC pipe as a mold and cut off the bottom of the bottles. Cut the 20mm PVC pipes into 10 x 1m and 20 x 8.5 cm pieces, and assemble with the T-connectors. Cut and paint the cartons, as well as the one-meter long pipes. Assemble according to figure B.

The panels must be placed at least 30 cm below the tank and be sited on a south facing wall or roof. To optimize heat absorption, the panels must be mounted at the angle of your latitude, plus 10°. In London, for instance, the panel’s inclination should be 61°. We recommends that the plastic bottles in the panels should be swapped for new ones every 5 years: ‘Over time, the plastic becomes opaque, which reduces the heat caption, while the black cartons can be repainted.’ So once the bottles become opaque it is time to replace the bottles and send the used ones to the recycle dump.
