the earth is a good heat sink. A straight down well 150 ft deep does not need water to sink a lot of heat per hour from a heat pump. And since the fluid going down the pipe is only slightly lighter than the fluid coming up, there is not much lift involved.
There companies out there that just install these loops.
One I have never dealt with but is all over the country is Loop installers: Loopmasters International, Indianapolis, Indiana.
