DIY Solar Water Heater
This little project might be one of the most simple DIY heaters I have come across. With a few items from your local hardware store, you can build your own solar water heater that is portable and perfect for any outdoor adventure.
If your local store's inventory is limited, I have included links to purchase online.
Flat Head Phillips Screws (4 pack) #8 x 1in #10 x 2.5in
1.5" #16 Wire Nails
3/8" Square Dowels
23.7" x 23.7" Sheet of Plywood
20" x 20" Sheet of Plywood
20" x 20" Pane of Glass
2' x 2' Lumber Cut - (2) 23 1/8" & (2) 20 1/8"
Here is a step-by-step tutorial:
Loosen the copper and divide the 20" x 20" into 4 equal quadrants.
Lay the copper on the sheet leaving 24 inches unattached at the beginning. Start to attach the copper to the board by drilling two holes on each side of the tube and zip tie.
Continue drilling and zip tie-ing the tube to the board until you have 2 feet remaining. Cut the ends off of all the zip ties.
