Per my other thread on GeoThermal-Math Madness, I'm still doing research on putting in GeoThermal unit.
My question today stems from a comparison I'm doing of Geo vs a Hybrid type of system. Using this xls file..
http://www.eia.doe.gov/neic/experts/heatcalc.xls there's a section at the bottom that talks about HSPF efficiencies and how there are variances across the US.
Essentially, an 8.6 HSPF unit here in central Indiana would really only yield a 5.9 HSPF due to seasonal impacts. If that is in fact true, then my GeoThermal option looks a lot better.
So, is the xls file correct in that an 8.6 rated HSPF in central Indiana is going to be more in the 6.0 range?
