calculated head loss: 1) Length of longest circuit, round trip. 2) add 50% for fittings. 3) multiply .04 example 150'+75=225'*.04= 9ft of head The height of the building has nothing to do with the pump. The water pressure has to do with the height of the building.

Awesome, you solved my issues with my flow rate in 1/2" pex, much higher head then I expected. Now I have the correct pump.

Louis, your app is no longer on the iOS app store. i have a question for you. I am preparing for a mechanical/distribution panel for hydronics in-floor heat. i have 2 zones. zone 1 has 7 loops with a 7 loop manifold. each loop is approx 300' of 1/2" Pex. Zone 2 has 3 loops with a 3 loop manifold. The loops are in parallel cct and the manifolds as well. From your calculations; my longest single loop is 300'....300X1.5 =450......450x0.04 = 18. is the head loss of 18 accurate? why do i disregard all the other loops? i am trying to size the circulator that i would like to deliver1-2Gph on all loops (zone 1 will require 7-14gph into the manifold = 1-2gph per loop). in my design i will have a primary circulator and 2 secondary circulators (one for each zone) thank you.
