I modeled my first geothermal system (GSHP), but my numbers are not quite right. On my Energy Cost Report the heating and cooling values are what I expected, however, the pumps consume substantially more energy than expected (on the order of 20X more).

I then went to the Equipment Energy Consumption report to see what pump was consuming all the energy, and found the Plant Geothermal Pump consumes a ridiculous amount of energy(4 million kWh instead of a few thousand). I also found that my geothermal system has a max block coil load of 18,000 ton instead of the expected 600 ton. All of the other plants and systems seem very reasonable; it's just those two issues.

So, my question is, are these two problems related, and what could be causing my high Plant Geothermal Pump consumption and high max block coil tonnage?

Your help is much appreciated!
