Title: Pex/Pump sizes
Post by: tinfoilhat2020 on July 27, 2015, 10:31:46 AM

what size pex are u guys/gals running??????? 1" or 1 1/4"?????  I currently have all 1" lines installed for house loop and shop loop. B&G NRF-36 for the house loop and B&G NRF-22 for the short shop loop.  House loop is approx. 250' total and hit 3 exchangers along the way. Shop loop is only approx. 30' total and only hits 1 exchanger. Im hoping that this is adequate....one of the dealers i spoke to kept trying to sell my on the 1 1/4...he went as far as to try and convince me that i should rip all my previously installed 1" lines because the boiler calls for 1 1/4"...I hope i will be ok!!! to much work to redo, at least for this year!

Any info or insight would be great....i would like to know what size lines or pumps you guys are currently using?????

Ran Logstor from the boiler to the house and the shop, slightly over 1” inside diameter.

Used 1 1/4” lines in the shops to each heat exchanger but smaller pumps. Was actually more cost effective to pay for bigger line but ended up costing less with smaller pumps.
