Hydronic mixing block

Viega’s Hydronic Mixing Block is a mixing device and boiler control with a built-in circulator and microcontroller that provides a user-friendly solution for controlling radiant heating systems. Easy to wire, pipe and program, the Hydronic Mixing Block combines mixing, control, air elimination and a pump in a single unit which simplifies radiant installations. It also provides either a fixed or reset water temperature via start/stop or constant fluid circulation.
