That's a tough one! I specialized in PICV valves for years and my two-cents worth is, since PICV valves are a dynamic valve meaning they adjust all the time automatically and loads change from minute to minute and day to day, it's almost impossible to do an honest assessment and/or a accurate test. With that said, anybody who says they don't do any good and claims they don’t save money through reduced pump loads or improved delta T's, is not educated enough in this field. PICV Valves do create better Delta T's and do reduce pump loads through faster, better system water balancing when VFD's are properly utilized. I am no longer directly involved with PICV valves, so I have nothing to gain here. PICV Valves work and save money! Check out YouTube.com/PICV Valves
