  • DHW flow 1, with total power P1, diversity flow v1, and diversity factor f1

  • DHW flow 2, with total power P2, diversity flow v2, and diversity factor f2

...

The question is : how to calculate the diversity factor f3, total power P3 and diversity flow v3 for DHW?

  • P3 = P1 + P2 (first law of thermodynamics)

  • f3 is recalculated based on the applicable diversity standard, applied on the TOTAL amount of tapflow or TOTAL amount of dwellings on the secondary side.

  • the supply temperature t3supply is defined by the user

  • the return temperature t3return is calculated as the mixed return temperature (v3 * t3return = v1 * t1return + v2 * t2return)
