Just a thought for you... I would worry about mold growing in the pipe over time. The air passing through the pipes might pick some up and blow it around inside your building. Could be an irritant, esp for those with allergies and such.
You could probably design a system with an air to air hx to isolate the conditioned air but would be more $$ and you'd need some calcs to see if it is even worth doing.

What I am thinking is to bury a 6-8" solid plastic tile about 5-6' deep and circulate air through it to partially heat and cool the shop. I have plenty of room to bury the pipe, and can put in several hundred feet if needed. I planned to use only air to circulate through this and run the air right into the shop. Do any of you know if this will work? The shop will be insulated and I plan to use radiant heaters to supplement this as needed.
I am also considering heat in the concrete floor with water and a water heater instead of or in addition to the geothermal air system.
Any thoughts are appreciated.
