Hey, I wanted to let you all know, I now have a free hot water source for my old Maytag Neptune 4000...well, the heat is free...I still pay for the water.
As you know, I feed the Neptune with a garden hose which is of course, cold water only. Until today. I strung the hose over the hot driveway in the hot sun and 50 feet of garden hose produces plenty of hot water for the initial fill.
So next, I'm thinking of cobbling together a solar heater for the roof of the garage. Any ideas from you folks out there?
Materials, mounting, design, etc?
