The only advantage to wells, is that the average temparature deeper is warmer (55 degrees where I live), so you need less pipe.
Did I mention that as soon as the pipe is down the hole, they fill it back up with a grout around the pipes to enhance conductivity and prevent contaminating the aquifers?

Well, I have a 'standard' lot size... but not really, it is smaller because I am on the wrong part of a cul-de-sac... so, 125 x 65 or so... not enough ground... guess I will be going to the high efficiency unit when I replace...
