Philip's Fiji Island DIY Thermosyphon Solar Water Heater

Philip lives on the beautiful Pacific island of Fiji, where the scenery is stunning, but the utility rates are on the high side.
This picture just knocks me out -- wonder if Fiji needs another solar guy?
Philip worked out a nice and simple warm climate thermosyphon solar water heating system.    The system is very simple: no pumps, no heat exchangers, no differential controllers, no anti-freeze.   Just a PVC storage tank located above the collector, and the thermosyphon effect does all the rest.

The total cost was only $250 US.

Philip provides the details on how he designed and built the thermosyphon system...

Much more on DIY solar water heaters for climates from the Artic to Fiji...
