The Proper Design Criteria for Selecting the Appropriate Pump

WebA: An open loop system has an average water temperature of 52 degrees and uses the water well pump to deliver the water to the unit. A closed loop system averages 40 degrees in the winter, 70 degrees in the summer, and uses a small dedicated circulating pump. Factoring in these minor differences, the cost of operation is nearly the same.
