System separation HeatBloc DN25 2x1"ET - 2xF1", 3bar, Si-Grp MAG connection, 25kW

System separation:
System separation is used for heating circuits, which must be decoupled from the boiler circuit. The heat exchanger provides optimal heat transfer from the primary circuit to the secondary circuit.

Application:
For systems with oxygen injection such as underfloor or wall heating systems with diffusion-open plastic pipes, open expansion tanks or intermittent oxygen injection (e.g. new constant refilling) and to separate/protect the boiler circuit with old systems and during boiler exchange. An extension with a mixed/unmixed Heat Bloc is required to complete a separating system.
