We have around 2 1/2 acres of property to work with so you would think that creating 2 300' trenches would be easy. As you can see by the pictures, we had to snake around several trees and ultimately had to work really hard to achieve our total distance of 1200'.
The trenches we dug are around 3' wide, 5-6' deep, and at minimum 10' apart. We would have to dig the entire first trench out to the 300' mark, layout out the tubing and then start doubling back after filling in the hole with around 18' of soil on top of the original tubing. Each leg being 300' gives us 600' after doubling up the tubing at 18" higher.
It is hard for me to believe that this tubing will carry water out into the earth from the home, travel through the 1200' of the earth, pick up around 10 degrees of heat travel back into the house and then the furnace inside the home will be able to harness that energy to heat our home. You just gotta love it!
