Initial investment is what you make it. Solar air heaters are built daily for nothing. Some people just don't understand free.

I'm guessing all of those nay-sayers are people who sell electricity or gas.

One wants all of the heat possible on the inside--to wit, inside the insulation. If a house is well insulated, I could not care less how hot the outside walls get and/or the attic.

I've had passive solar in a house in New Mexico and it significantly cut heating bills.

Sorry, to all of you people saying, "Oh don't try this; it doesn't work. It absolutely does work."

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.

Sun heat is everywhere and why block it even with your well intended solar devices even on the roof! Your house needs all the solar radiation it can get. So move all your solar devices out of your house sun exposure even passively

Yes some solar collectors my shade a portion of the house, but that has to inconsequential, if the collector directly heats the interior air of the home, where we want the heat. Just heating the exterior surfaces of the home is just wasting the solar available to the home. I may have mis understood your first sentence. :(

sure..get our other book on solar radiation across america, its also free online at NREL, but if a solar oven in he summer will bake bread, don't you think your entire roof would heat your house in the winter time?

@knowpub not where Iive with only a few hours of dayligth each day in winter..

People just dont understand the concept of  initial investment.

Steve...you're the balls man!Not trying to be smart but is there a quantified measure of the amount of space this solar heating setup will provide?

Your humble student...
