Changes as of 

  • Some minor bug fixes

Changes as of 

  • New manufacturer specific parts are available:
    SWEP heat exchanger series B16DW, B85, B28, B10T, E8LAS, B15T, B320HTH, E8AS, B320LTH, B35TH0

  • The Volume Weighted and Power Weighted Return Temperature (VWRT and PWRT) are added to all sensor BCs.
  • A warning is added when implementing your data in the data file BC to specify when to set the "relativity to simulation start time" parameter. On the top right corner, there is also a link to our wiki page where everything is more thoroughly explained. (Generators)
  • Some minor bug fixes

Changes as of 

  • The volume calculation method for expansion vessels is separated. The pipe volume and storage vessel volume is visualised separately from the "system volume" which is calculated using the DFTK17 method of 10 liters/kW installed power.
  • Some minor bug fixes

Changes as of 

  • 2 new BCs have been added, a “Design Condition Override” for both heating and cooling. These BCs have the possibility to change and lock the thermal power and/or the temperature regime. More information can be found in: System peripherals
  • Some minor bug fixes

Changes as of 

  • The Standard Tap Profile Generator BC now also has a re-randomize function. This means that in default the tap profile generator doesn’t change anymore with every new executed simulation. The user can set the re-randomize on when the tap profile in the current simulation isn’t desirable. This function was already active for the Eco-Design Tap Profile Generator.
  • Some minor bug fixes

Changes as of 

  • We added a new component : insulation on heat exchangers
  • We added the possibility to do sensitivity analysis on zone parameters,
    which can be used for (semi) automated load matching
  • Some minor bug fixes

Changes as of 

  • We added a new simulation method for DPCV's (P-control over multiple timesteps)
      which can be activated if you experience simulation difficulties with the default simulation method
      see Frequently Asked Questions for more info
  • Some minor bug fixes

Changes as of  

  • We added the possibility to export Pareto graphs using the export icon
  • We added 2 graphs to the Pareto dashboard



  • Normal heat exchangers now have the same UA parametrization possibilities as HIU’s, so not only a lookuptable anymore
  • We added more information, and information filters on HIU's
  • Some minor bug fixes
