These large-scale systems are characterized by a buffer tank with auxiliary heating and an external heat exchanger. They differ from one another with regard to space heating.

On the page System Definition (System name), tab DHW-circuit has priority over the auxiliary heating can be made. This causes the DHW standby tank to be supplied first in the event of insufficient boiler power.

The system consists of the following components:

  • Collector loop connection, contains
    • Collector array, contains
      • Collector
      • Shading
  • Where required, heating loop
  • Buffer tanks
  • Auxiliary heating
  • DHW supply, contains
    • External heat exchanger
    • DHW standby tank
