Has anyone any experience or knowledge of drilling diagonally for traditional water source/ground source heat pumps?
I know that the diagonal method (30 degree angle) is popular among the DX Geothermal Installers, but has it ever been tried for the traditional closed loop geothermal systems.
So far from my research, I can only identify resources describing a directional drilling method, or a trenchless horizontal method.
Any thoughts, input, or references from this forum would be greatly appreciated. |
