    Divide this number by recommended length per circuit 1200 / 300 = 4. If number has a decimal round it up to the nearest value. Number 4 indicates that the radiant heat system requires a 4-branch radiant heat manifold set. Divide the total length of tubing by number of branches and you will have an average tubing run per circuit 1200 / 4 = 300ft.

    Full Port Ball Valves vs Standard Port ISM

    Full port ball valves provide almost no resistance to flow through the valve. Summary The flow path through a full port valve body is the same size as the flow coming into the valve and leaving it via its tube or pipe connections. Standard port valves have smaller bodies overall with a corresponding narrowing inside the valve body.
