ACGC, are you running the pond water directly through the Source Side? Do you not have any problems with 'organics' plugging the Hxer?
That definitely is a warm house.....we keep it at 20 degC here.....
What make of GHP is it? Have you seen the new variable 7 series from WFI?
Bret , hubby made this heat pump..and it's directly from the pond either heating cycle or cooling . No organics yet but we check it often in the summer as well as winter. He also heats our water from the heat exchanger as the photo shows. But if any body but himself knows what the wiring diagram is....lets just say if he dies before me , I'll just put in window shakers
mourning Bret & the gang !! It's Friday after Christmas and I'm looking forward to the week-end. Cleaning up all those decorations and putting away the tree for another year. Y'all stay safe out there.
