I have remote cabin and have placed pex pipe stapled up to the floor with AL plates made from flashing. I plan to create a solar storage unit from water contained in some form of tank likely 600-1000 gallons of it. To heat the water I'll need some sort of collector.
I have seen a number of articles on building solar hot air collectors from stacked pop cans. So I have been thinking this might work for water also.
The thought is I'll leave the tops on and drill/punch a 1/4" to 3/8" hole in the bottoms. Then silicone them together as a stack. I'll feed it a rate to keep some water trickling through the cans using a some sort of header pipe. At the bottom cans I'm thinking a piece of gutter with an inslulation top with holes drilled to accept the cans. Box design would be a inslulated box covered with lexan or Tuff-R (trademarked) sheeting.
At night I'll either quit pumping water through and allow drain back or I'll have a valve such the water ciculates to prevent freezing but not allow the chilled water to get to the storage tank.
Comments,thoughts? Has anyone tried this before?
Cheers,
