Not every geothermal system is a simple one-heat-pump installation.

Our October article explains when contractors may need a dual-circuit geothermal flow center — especially when two heat pumps are connected to one common loop field.
We also break down where B&D’s EA and QT-EA Flow Centers fit, and the simple difference between the two.

Pro Tip: Don't overlook pipe sizing when designing a geothermal loop. Undersized piping can increase pressure drop, reduce system flow, and force circulators to work harder. Match pipe diameter to the required flow rate, loop length, and system design before installation begins. Better calculations upfront mean fewer headaches during commissioning.

Glycol concentration drift is a slow, invisible risk in closed geothermal loops. Over time, minor leaks, system additions, and top-offs without proper mixing can dilute protection below freeze point. Annual testing with a calibrated refractometer, and maintaining a log of all top-off events, is the simplest way to protect a loop that cost thousands to drill.
