ModCon Boiler Piping for Peak Performance

Modulating condensing boilers are become more and more popular in North America, but piping technique is different than piping a standard cast iron boiler. Bob "Hot Rod" Rohr, Caleffi Education Manager, explains how to pipe them correctly. He addresses: the common heat exchanger designs, the top three issues in piping a Mod Con, how Mod Cons can benefit from additional mass or fluid capacity, pipe sizing, the importance of adequate flow rate, primary/secondary piping, and the role of various hydronic components used in a ModCon boiler system.
