3/8 pex lines for tiny zones

Member Posts: 5,189
I haven't done 'new work' in forever, mostly chop-swap. As recall, the 3/8 pex/plastic lines will carry a good amount, 1 gpm under normal circumstances? Up to 10000 btu if we use traditional numbers? I have a guy that want's micro-zones (yes we have a buffer tank)
Thanks for any input.

With 3/8" PEX, you could flow as much as 1.3gpm. At a 20°Δ, that's a max of 13,000 BTU's.
8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour
Two btu per sq ft for degree difference for a slab0 -
depends on the loop length.
The PPI online calculator is good to run examples
