I’m in NW Pennsylvania near Erie, Zone 5.
I want to build several solar heat exchangers so I can be comfortable to of
fer a workshop at our Permaculture Farm.
I’m planning on using the 3 screen method.
1)Would the exchanger be more efficient if the sides were made with 2x12?
?? boards? More volume for air?
Cost is not a factor since I have my own lumber on property.
2)Would larger hole (8” to 12”) on top where hot air enters
room be more efficient to move air, even maybe without a fan? If so what
size should the bottom hole be?
3)I know it is impossible to measure the “average” heat gai
n due to sun, cold, climate and other factors but is there a general idea h
ow much gain happens. Basically to prove to people it is worth the labor a
4)If you have any new developments regarding the solar heat exchangers, I w
ould like to know before I build them.
Thank you very much,
