I now have finished drilling 3 water wells with the rig me and the boys
built using plans from http://drillingfab.com/books . I want to drill
and install geothermal ac/and heat for our home. The best thing is that
geothermal contractors charge 1000.00 per hole for the geothermal and
it takes 2 holes per ton of a/c. with our own drilling rig we can save
8000.00 for the geothermal holes. i found some places selling the
geothermal units. the info and spec clain to save 45% to 65% of
electric cost, and with light bills getting bigger than house notes you
have to do somthing.I plan to start thissoon so i'll keep you posted.
my neibor want a system too, i may get rich if he pays me in somthing
other than barbeque.
