I will try to answer your questions based upon my research and my intuitiveness that substitutes for sparse information on passive solar construction. (Early on, I tried to make nice with Don Stephens in order to capitalize on his thinking but, after feeling rebuffed, began using John Hiat's self-published book as my principal guide).<br /><br />My reasons for eliminating the solar chimney are given in the blog post. I still think that the issue is overheating rather than a lack of heat transfer from the conduits. I would say, however, that the faster the air moves, the less heat it gives up to the surrounding soil; the pipes themselves, if anything, are countervailing insulators, not heat absorbers. That is one reason for using thin-walled corrugated pipes instead of thick-walled PVC. As explained in the post, however, the main reason for corrugated is to create turbulence and slow down the air flow to give it more chance to release heat. <br /><br />It will be interesting to see over the years if the system will perform as envisioned. By giving up conventional HVAC cold turkey, we are gambling that we have done enough things right. I plan to continue blogging on the success of the system over the rest of my limited lifetime.<br /><br />Jerry Younghttps://www.blogger.com/profile/06917529268126341069noreply@blogger.comtag:blogger.com,1999:blog-1418498126670813334.post-50950254999254364512018-02-27T06:40:33.540-06:002018-02-27T06:40:33.540-06:00Hello
I am interested in AGS and PAHS since I met...Hello <br />I am interested in AGS and PAHS since I met Don Stephens @ Malcolm Wells mail list /forum in 2006.<br />I just ran across you site and blog . <br />I am interested about the performance of the GAS . you mentioned that you are skipping the solar chimney . I never build a house with AGS , but I think that the solar chimney gives velocity of the air movement and some extra security that the air will move in border line conditions (some clouds). Plus the faster the hot air moves the less it gives up heat to the surface of teh pipes (am I right on this ? )<br />Keep us informed on your project , please - it is very inspiring!<br />Best regards , <br />Martin MiMhttps://www.blogger.com/profile/17536507576851647411noreply@blogger.com
