Reply #79: Partially heating your home with solar energy is extremely inexpensive

[GumboYaYa]

and easy to accomplish. Try this link: http://www.hotboxsolar.com/gallery.html to see solar air heaters at work. You can purchase prefab solar air heaters for $500-$1,000, but it is also easy and inexpensive to build one on your own. I made one from recycled aluminum cans using a south facing basement window and it works great. On clear, sunny days, we don't need to use the heat in our home. Our gas bill is less than half what it was during winter last year.
