Web5 de out. de 2024 · In general, these so called open-loop systems are more efficient than closed-loop systems. This is based on the fact that water is the best carrier of thermal energy (very high specific heat capacity 4180 J/kgK). Having this in mind, we can say that water is not only essential for drinking purposes but is also an important energy source. WebAn 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.
