T_BACK PRO is a system that keeps constant the return temperature of the solid fuelboiler (firewood, pellet).

Through the 3-way thermostatic valve the system bypasses the water to the boiler flow on the return way up to the flow temperature set (55°C) is reached.
The valve proportionally closes the bypass and opens the return way;
In this case it allows the total circulation of the water to the users and the heating boiler in order to reach quickly the proper working temperature, prevents damages by smoke or soot inside the chimney flue and avoids the phenomenon of condensation in the heating boiler.

The unit is available with our without pump
