A quick walkthrough of how the DIY solar water heater works. The full build guide PDF is available free at: https://cdata.oho.wiki/images/8/8e/Os...

The design is efficient, robust, easy to build, and generally more effective than pex or copper pipe based panels.

Thanks to Open Source Ecology Germany (https://opensourceecology.de/) and the Open hardware Observatory (https://en.oho.wiki/) for putting together this animation and build guide for the panel design.
