Guest speaker Julius Ballanco, P.E. and acclaimed plumbing columnist, describes how to properly install hot water recirculation systems that incorporate protective thermostatic mixing valves. He begins by giving an overview of the importance of scald protection, then moves to an overview of the various types of mixing valves available, their intended uses, and their corresponding ASSE rating.
Bob "Hot Rod" Rohr, Caleffi Education Manager, explains the various types of on/off zone valves common in the market today, how they work, their relative strengths and weaknesses, and how to use them in application.
