How to build a solar water heater, simple DIY project. Save a month on power bill. Mark Patrick.
Step by step directions and have free hot water even if the power is out. A simply easy way to do it yourself. No pumps or controls completely passive. We start with the glass from old sliding glass doors and use a water heater as storage tank. I got the glass and tank for free. Watch me make it step by step. Great science project. We sell glass and frames too. Check out my other video on how to make a simple wind turbine.
