Geothermal greenhouse pipe length

[AlfredRussellWallace]

I've got a 26' greenhouse (not built yet) which is going to be at ground level and I want to put in a geothermal system. Is there a place I can go to for ways to work out the length and amount of pipe system to bury at 8' depth? I'm in Zone 5-6. Thanks.
