[General] General Digest, Vol 29, Issue 6

[Ethan Chew]

Interesting,

      From this map <http://www.geo4va.vt.edu/A1/A1.htm> (about 1/3 down),
soil temperatures 30' down are ~62 degF.  If we can get a ground loop of
sufficient size and depth, we can make use of that temperature for the
entire shop.  The only issue is that we are on rented property and are
limited in how deep and far we can dig.  The alternative is to rely on water
from the tap.  However, that may not be feasible since I have observed the
tap water to come out pretty cold in the winter.  So I assume the water
lines are 10 feet down or shallower.

                     - Ethan
