Thanks Jersey - Ladia, That's the kinda input I seek. Thank you. Considering we are talking about a slab area of 28' x 27', what would you call a good idea for amount of runs of 1/2" id?
The general rule is to have all loops associated with particular manifold of similar lenght. I think about maximum 200-300 ft long. Some of the manifold (in ex. Rehau) have built in rotameters (flow meters) for each loop so adjusting the flow and balancing the loops is very easy. It is better to err on the short side I suppose. You can always limit the flow of short loop but not necessarily the other way around. As I said before I am just informed amateur so ask the proffessionals for second opinion.
