Zespół hydrauliczny: wlot ciepłej wody użytkowej / powrót grzewczy De Dietrich 7680849

The hydraulic group DHW inlet/heating return is a combined manifold that manages the flow of domestic hot water (DHW) and heating return water in a boiler system. This component integrates valves and connections to ensure proper circulation and pressure regulation. If it becomes blocked or leaks, it can affect both hot water supply and central heating performance. Replacing this hydraulic group is a precise repair that restores system efficiency. It is an important spare part for boiler maintenance and repair, particularly in combination boilers.
