Often, it is not required to draw a full energy center plant room from scratch.
Most combinations are already available as a template in the inspiration library, for example like below, a cascade of boilers was required. By simply navigating to the inspiration library, clicking on the production units needed (in this case just boilers), and clicking insert, the template gets loaded into your model.
...
After the model has been inserted, all parameters should be checked and updated toward the actual installed situation. What follows is a list of parameters to check, however, this is not the full list and every single project should be looked at critically.
Boilers
Boiler capacity
Water volume (by clicking the pencil icon next to boiler capacitance)
The KV-value through the boiler (this can be implemented as the pressure drop over the design flow by clicking the pencil icon)
The KVS value of the on/off valves
Insert pump curves
Set correct pipe diameters if known, otherwise, unlock them and Hysopt will calculate an approximation.
...
Distribution
More information on different distribution options can be found here: Hybrid production Heating
For the example, a parallel production was used, in which case the primary power percentage should be filled in. This value lets Hysopt know how to divide the design flow over the inlets. The exact value depends on the boilers installed and, if all boilers are the same size, is already filled in correctly in hysopt.

Low Loss Header:
Often, a low loss header is placed, which hydraulically separates the energy center and secondary side. No special parameters should be filled in, however, it is important to always look at the pump control in this case.
...
Heat exchanger:
Another option for hydraulic separation is a heat exchanger, similar to boilers, their capacity and KV-values (pressure drop) need to be filled in. Capacity can be done using 2 methods:
