Hydraulic separators, as the name implies, are manifolds whose assembly in a heating system allows to separate the primary circuit of the circulator from the secondary one of the distribution. In this way, interference between the circuits is avoided and any anomalies related to flow rate and head can be corrected.
In addition to this function of separating the circuits, the hydraulic separator also has the function of maintaining the correct functioning of the heating system. In fact, it also acts as a dirt separator thanks to the presence of a drainage valve that allows to eliminate the impurities present in the heating water. In addition, the separator is equipped with a vent valve that allows you to eliminate air bubbles from the system. To facilitate these functions, drain and vent, the hydraulic separator is mounted vertically.
An interesting aspect concerns the material. Many heat exchangers are made of steel for the typical resistance of this material. If it is stainless steel, there is also the advantage of less heat dispersion.
