A method of forming an energy transfer loop in the earth has the steps of connecting a tubing to a nose member, extending a liquid delivery pipe to the nose member, pumping a liquid through the liquid delivery pipe to the nose member, jetting the liquid from the nose member so as to form an excavation in the earth and pushing the nose member downwardly through the opening in the earth a desired distance below a surface of the earth. A jacket can be affixed around the liquid delivery pipe so as to allow the liquid delivery pipe to be removed from the nose member subsequent to the installation in the earth.
