My propane bills, to heat my home in the winter, have been so high, I'm thinking about converting to Geo Thermal setup as my primary AC/Heat source and using my Propane heat as the emergency backup. The dang budget plan is almost $200/month and I don't even get filled up for 6 month!

From my understanding, the installation is pretty straight forward and most of the cost is in digging. So now I'm thinking about costs...

Assuming I can dig a trench, can someone tell me how deep and long it would need to be? Does one need say 100 ft long for ever 100sq of home? Can I snake the trench so it's a foot apart or does it have to be 2 or 3 feet apart?

I'm trying to figure out how much of my yard has to be torn up since I can't afford to have a well drilled. Also can one purchase the parts for a Geo thermal setup to do it as a DIY project? Is there a break down of costs I might be able to find somewhere?

Thanks!
