DIY Solar Heater: Top 20 Tips How To Build and Use a Solar Air Heater: (Power Generation) Paperback – January 24, 2017

Only 4 pages include any info to build anything, the rest tells you every which way how good solar heating is and why! Is included blurry obvious photocopies of basic illustrations coming from another source such as the internet. It is embarrassing.

This book is full of information. It's not a huge book, but not an article by a long shot. There are photos, illustrations, graphs, and all kinds of information- far more than necessary for most people. If you are interested in building this I would recommend the book.

Very limited info included
