Hello all, Quick question concerning conflicting info I am getting locally. Quick overview of the project: - new construction 4200 square ft home - one 4 ton unit in the basement - one 2.5 ton unit in the second floor - 8 individual loops of 800 ft all terminating in the basement Conflict: The original thought was to run all 8 loops into a single supply and return manifold, take that supply and return to a 4 pump QT-EA flow center. This would have two pumps for the second floor unit and 2 pumps for the basement unit. The nice part of this, in my mind, was that when one unit is working and the other isn’t, the working unit would have the benefit of the entire 6400 Ft of loop field. Also, when the kids all move away and we close down the second floor, my basement 4 ton unit would have the luxury of the entire loop field. The problem is that I have a local geo professional helping me out who claims that running both units off the same loop field is a recipe for disaster... he worries that one is going to steal from the other? He wants me to run 5 loops for the basement and 3 loops for the unstairs unit. I am just not sure if I follow the logic there and wanted to get some other opinions. I can’t be the only person to run two units off one loop field. Thoughts anyone? Is there a correct way to do this?
