What about drilling one vertical bore hole well and using it for your return to the water well?

Alternatively, your idea of doing a horizontal loop could work, but do you have sufficient space (and soil free of rock)?

So long as you keep the horizontal loop below frost depth (4 feet in your area?), I don't think a glycol mix is needed. But be aware of where those pipes come out of the ground!

I know of a guy in NH that uses water in his horizontal closed loop field and he has a fractional TACO pump (1/20th HP) that is always on in the winter to prevent freezing. Then a larger pump kicks on when he needs the loop field.
