http://www.ush2.com/where_to_start.htm How to heat your home with solar hot air. This is so simple, some wood, and glass, and you can get the glass for free, listen to the promo. This book has solar hot air heaters that will pay for themselves in weeks or a month or two. Step by Step, full illustrations and complete materials lists.
Ever notice that any solar heater on the outside actually block sunrays and leaving a shadow behind it... It is far cheaper to put a aluminium foil reflector on the ground to reflect the sunlight that would otherwise hit the ground unused. Also put more reflectors in the area that can reflect sunlight back against the colder, damper northern side of your house.
