The Homeowner's Handbook of Solar Water Heating Systems: How to Build or Buy Systems to Heat Your Water, Swimming Pool, Hot Tub or Spa Hardcover – January 1, 1983

I was surprised how old it seemed. A lot of the solar projects to centers on are mirrors used to heat black metal rooftop water tanks. The kind of things you'd associate with low income tenements in the 1920s.

The book has a tiny bit of useful information, but it is EXTREMELY outdated. There is plenty of more recent and therefore more relevant information out there.

Good

It is a little dated, but it has the basic principles that I have been looking for. The product was in good shape and arrived promptly.
