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 K31, K32 and 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 2:

Extension of already existing heating circuits / installations with a pump on the primary side and high

flow temperatures (bypass operation in addition to

the radiator circuits or operation with solid fuel boiler and 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.
