Is anyone using geothermal heat to heat a green house.  For example pumping air threw a pipe burried in a trench 200' feet long 6' down?   Or pumping well water trew a hose under the stock tank? 

Maybe I should have asked the question before I burried the pipe Hmmmmm.

We are in Gainesville, North Florida I do understand the warmest the air comming out of the ground in this are will be about seventy degrees but at least we can capture that heat being cost effective.

That makes sense,

Rob, I have just watched every one of your videos and they are fantastic - that is an amazing project and looks like it will be a fantastic setup once everything is completed.  My hat off to you!

I jsut put a rocket mass heater in my greenhouse:  http://youtu.be/_DhCRUMxnNM  It's working quite nicely so far!

To answer the earlier question about heating the water instead of the air.  You can heat the water to about the same temperature as the air.  If you rely on all the heat for your greenhouse from the water, you will run into big problems.  With the air being cooler, the water will condense on everything and keep your humidity near 100%.  I had ice forming on all my polcarbonate...even froze the door closed so I couldn't get inside!

I guess I will have to find someone local to do it for me.  I'm not very mechanical. That's what I get for going to law school!!!

Kou go to youtube there are clips there explaining the concept even if you have some one else do it for you it would help you if you understand how it works.  My hat is offf to the guys that put this stuff on youtube for us.

I know I'm arriving late to this party, but Penn & Cord seem to have found the right equation >

I found this site while looking for a way to heat a big hoop house. I think that it is a great plan if you can do it from scratch.
