Hi--
I'm advising my plumber re pump model choice for water circulation in a closed-loop system for radiant floor heating using a masonry heater. We're looking at the Taco 007 series. One pump will used for the storage tank- heater loop (copper pipe, ~7gpm) and two pumps will be used for the upper and lower floor radiant heating loops. All are closed systems. My water has some iron content. The efficiency of the two pumps looks very similar. Is there an advantage with using a bronze or cast iron pump like longevity or ease of repair? Thanks for your suggestions! Rob
