Why not open loop?
Green_Masheen,
The short answer is that I live on a 50' x 100' city lot and my options are limited by available space.
I'm hitting wet sand at 17 feet but I don't think that there's enough flow to do open loop.
I could have rented a small back hoe and dug trenches and put in a slinky configuration. It would have gone faster.
The way I'm doing it with boreholes is more work, but I'm half done now with my loop field. The rest of the holes should take me less time, I've learned how to do it better and quicker.
I've also built and improved and discovered new tools to make things go easier. More about this later.
Hope this helps...
Best Regards,
