The Transition Sebastopol Energy Group will host its second workshop on how to build a solar batch water heater.

The simple design is an insulated box with reflective interior and double pane (re-used) sliding glass door to heat the water in a steel tank salvaged from a used water heater core. The hot water can be used directly or can be used to preheat water feeding into a conventional water heater, allowing it to work more efficiently. This concept can be also used to make a solar oven. Come join us at Laguna Farm for this fun, hands-on workshop!

• Learn an easy way to take simple materials and transform them into a practical appliance.
• Build a solar water heater in a single afternoon with others.
• Save money by heating or preheating your water with energy from the sun!
