New to the forum but I've been browsing here for a while . I'm going to be finally heating my pool after three years of a chilly pool. Due to my unique system figured it was time to join and ask the pros!
I'm installing a 150,000 btu heat exchanger, the problem is it's 200' from the pool. Not only that it's also 24' vertically below the pool. The specs for the heat exchanger call for 85gpm at the unit and max of 72 psi. I was thinking I would install a 120 gpm cartridge filter. I am going to run 3" pvc down to the heat exchanger and 3" back to the pool. The company that manufactures the heat exchanger told me to add 10 feet of head
For the unit.
My questions, how much head do I add for the filter, the 400' of 3" pvc, and how do I account for the elevation change?
The elevation change is what I'm least sure of. The pool pumps the water down to the heat exchanger but then back up to the pool for a net elevation change of 0. So do I just ignore this?
Also, 24' of elevation drop at the heat exchanger will increase my pressure by 24x.44=10.56psi, this won't put me anywhere near max psi of 72, right?
Thanks in advance! Glad to be a part of the forum.
