Grounded In Reality: Better Ground Source Heat Pump Design

Why do ground loops in moist soils sometimes perform better than expected? What ground loop design tactics can address building system imbalance? Engineers need to take more responsibility for their full GSHP designs, and these questions are a good place to start.

With a little guidance on ground-source heat pump design temperatures and a few rules of thumb for ground loop flow rates, most engineers are pretty comfortable designing the building side of a ground-source heat pump (GSHP) system.
