GPM in a hydronic slab system
This is as critical a setting as having the right amount of tubing and proper temp, etc. They all work together to give you maximum performance and efficiency. The GPM setters/meter are used to set the flow to each loop as they are rarely the same.
the more I do radiant the more forgiving I find it, but you still need proper design perameters to get it right. Have someone (contractor or supplier) enter your information in any manufacturers design software to get proper flow settings. You need this information also to properly size your circulators, etc.
This kind of system is a big investment and well worth doing right the first time.
