Outputs/mass flows

The Power/mass flows window provides brief information on mass flows or volume flows and heat outputs of the selected section.

Table 1. Components of the Mass flows window: Power range
Name of the component Explanation of the component Physical unit
Heating Specifies the heat output of the consumer. [W]
TWE Central Specifies the specified heat output of the central DHW heater. [W]
TWE Decentralised Indicates the totalised heat output of the decentralised DHW heaters (home stations). When moving over the value, you receive further information on the simultaneity and composition of the output value.

This value results from: TWE Decentralised= Total output of all decentralised DHW heaters (home stations)* Simultaneity factor.

 [W]
TWE Central Priority Specifies the specified heat output of the central DHW heater if it has been set with a priority circuit.
Note:
You can assign the Priority circuit property in the component properties of the central DHW heater.
 [W]
TWE Decentralised priority Specifies the total heat output of the decentralised DHW heaters (home stations) if this has been set with a priority circuit. The stored simultaneity is taken into account here. When moving over the value, you receive further information on the simultaneity and composition of the output value.

This value results from: TWE Decentralised= Total output of all decentralised DHW heaters (home stations) with priority circuit*simultaneity factor.

Note:
You can assign the priority circuit property in the component properties of the decentralised drinking water heater.
 [W]
Total TWE priority Specifies the totalised output of the DHW heaters with priority circuit. This value results from: Total TWE priority = TWE central priority + TWE decentralised priority (home stations). [W]
Total demand Indicates the largest value from the comparison between the sum of "Heating + DHW central + DHW decentral (home stations)" and the sum of DHW central priority and DHW decentral priority (home stations)". [W]
Producer Indicates the specified output power of the boiler. [W]
Design Specifies the smallest value from the comparison between "Total demand" and "Producer". [W]

The Mass flow and Volume flow tab in the Mass flows window shows the respective mass flows and converted volume flows of the above-mentioned components.
