On the right track? (Calculations)
Im fairly new to this so I'm learning as I go. I have a radiant heat system upstairs thats using 1/2" pex at 8" apart. I've calculated my heat loss to be around 5500 BTU/hr.
GPM = 5500/10,000 = .55
Head loss = 200ft loop...2*.51 = 1.02
Does this seam right so far?
If I had 3 200ft loops in a zone, would I multiply the head loss by each loop?
How do I know what my supply temperature should be?
