Complete station for mixing and circulation


Comfort and safety for hot water are combined in the compact station tubra®-Circu-mix. The integrated circulation pump reduces unnecessary water losses and keeps the hot water system at temperature as needed. At the same time, the mixed water unit with the thermostatic domestic hot water mixer ensures constant hot water temperature during tapping and circulation operation. This prevents overheating of the hot water network in accordance with standards.

The entire unit comes completely pre-assembled, including functional arrangement of the backflow preventers. The circulation pump is already pre-wired. The connections for the piping are designed to be easy to assemble and installation-friendly, enabling a time- and cost-saving assembly. Furthermore, the shut-off valves ensure high ease of operation and service.
