Hi Everyone, I am a GC, just built a new home for my family. Installed a WF 5 ton dual stage air unit. Enertech's design software said 420 vertical feet into granite would work, I have 2 wells at 230 each for a total of 460. System running all the time in winter. EWT is 30 degs , delta T is about 5-6 degs. Stage 1 kicks on, 21 mins later stage 2, 22 mins later W1 kicks on, 22 mins later W2 kicks on & runs for about 5 mins. Cycle runs for about 70 mins, off for about 5-6 mins then starts all over again. Dec power bill $ 770.00, 4400 kwh consumed. If I turn off breaker to elec heat what will happen? Any suggestions? Add a loop, can I add a horz. loop? System works fine in summer.
