Viega hydronic mixing block
Viega’s hydronic mixing block simplifies wiring, piping and programming for radiant heating systems. It combines mixing, control, air elimination and a circulator in a single, simple unit that makes wiring, piping and programming easy. The mixing block features three connections for simple installations with clearly labeled fittings and ports. The installer inserts the fittings, mounts the unit into the bracket and then ties it into the system. The block’s control offers an intuitive menu structure for quick, simple programming without sifting through multiple menus.
