If the attic is uninsulated this will cause more heat loss in the ducts. Ducts are typically around r-6. Sure, a system that is off will also loose heat in the ducts, but they will eventually approach ambient attic temp and stop loosing more heat. CrazyRabbit and Dave EV.

Hydraulic Losses : Hydraulic Losses are the losses occurred by … WebFluid entering a centrifugal pump is immediately directed to the low pressure area at the center or eye of the impeller. As the impeller and blading rotate, they transfer momentum to incoming fluid. A transfer of momentum to the moving fluid increases the fluid's velocity. As the fluid's velocity increases its kinetic energy increases.
