Hi!!! i bought the book of hugh piggott, "a wind turbine recipe book", i build it and itīs working nicely. i like very much how easy and effective is his design. For shure there are others designs much more efficient, but what i liked most of it, is that his design is simple, robust, works, and was tested and tested and tested....

Now i want to have some hot water, do you know anything similar to "the piggott windmill recip book" but for solar water heating???.


Thanks you very very much!!!!

Hi
There is lots of good stuff on the builditsolar site. In particular try builditsolar. I found a stack of frost damaged panels at the local scrap yard and have repaired three of them and they heat our spa 3 seasons. In winter they provide about half the heat. I have four more which I plan to set up to pre-heat water entering our electric cylender. Both systems will be drain-back types as described on the website above. Have a look at the "The $1K Solar Water Heating System" section.

Nice to build your own but if you look around on Ebay and Gumtree you can buy second hand at a good price.

I got a 300 litre rheem that was not pumping, turned out the controller was RS. I built a new controller using an Arduino for well under $50.

I would think postage might be a killer (Argentina )
Sometimes it just works
