Is there a downside to putting in extra loop footage? I was originally told by the well driller that I needed about 1200' of vertical loops for six tons, but am being told 1050' would work by the installer. Obviously, I would save money, but would it be better to have the original 1200' ? Would having more do something bad to the efficiency of the system? I am guiess=ing it wouldn't, that having extra might be good. But, I'd like to know what you all think. Thanks. I will be talking with both the well driller and installer shortly.
