I am trying to model accurately the pumping power for a primary/secondary hot water loop. I have my boilers, boiler pumps and secondary loop pumps all set, placed everything on a single Hot Water Loop. In reality, i have a third "loop" that is the preheat coil pump to recirc water in the preheat coil. This pump is small, but i want to account for it. Should i add it into the secondary loop pump power or should i create a secondary loop and attach it to my Hot Water Loop and then assign the correct coil to that and put my preheat coil pump on that loop? I would have to do this for 8 air handler preheat coils, and feel this could get messy.<div>
