The Taco Radiant Mixing Block makes controlling and installation of radiant systems easy. It is a variable speed injection mixing control, injection circulator, system circulator, and air eliminator all in one. And, it requires no special piping, no balancing valve, no closely spaced tees, no external controls, no complex wiring; just four pipe connections and your installation is complete.
