The adjacent half of full floor is as you suggest more heat loss/gain uniform and I plan the spiral out to in pattern. Is there a significant head or flow pressure difference in layout patterns that has to be balanced? I.E, can one loop be serpentine another circular and still be in same zone if matching length?

Opps, missed a C there. No problems doing the circuit either way and there should be no difference in pump head, just takes longer to put the tubing down when you have more bends.
