water well pipe and geothermal potential

green · 05-07-11, 10:01 AM

I have a water well, a 2" inch pipe deep in the ground( I don't know how deep), that's hooked to a small pump and tank which is used for gardening and other non potable water uses.

I know that my water table is high--we live between two rivers and the sump pump has water running year round, and it runs regularly.

How does one determine the extent to which this existing water pipe could be used for a small geothermal system-- perhaps to heat the basement or first floor.

I stumbled into this site, and am still catching up on a lot of information.

I have read about open and closed loop systems, but have found very little info on my type of water wells. My guess is that it's too small, but since it's there I am curious to know its potential.

thanks in advance
