System separation DN 25 (1") for HeatBloC®s
Application examples
The heating circuits recommended for combination with the system separations (36533, 36553, 36573) are listed on this page. Equipment and prices of the
heating circuits can be found on pages 101 (K31), 103 (K32) and 109 (K34).
Note: the heating circuits have to be ordered seperately. The assembly must be carried out on-site!
Application 1:
Extension of already existing heating circuits / installations with a temperature control on the primary side (mixed heating circuit with controlled flow
temperature or modulating boiler with boiler circuit pump).

Application 3:
Complete system separation with mixing valve control on the primary side. Ensures low return temperatures of the boiler and allows the operation of several
parallel heating circuits, f. ex. on a distribution manifold.
