My question is why do the Energy losses from infiltration rise (highest rise seen in april), when I'm trying to change the Potable water tank in system 44a to my own created Storage tank with the same configured Controller inputs/outputs?
Attached a project file with a system diagram before and after the change of tank.
Thank you
Pierre

Dear Pierre
Thank you for your question.
The answer for your question is that in the second system (when you changed the storage tank) you overheat the building a little. For instance, in April the average temperature in the building 1.1 degree higher in the second system than in the reference one. Therefore, for the second system the temperature difference between interior zone and ambient becomes larger. Since this temperature difference plays and important role (namely higher temperature difference between interior and ambient -> higher infiltration losses), infiltration losses are higher for the second system.
I hope it helps you.
Best regards
Artem

So the new tank is overheating the house? If so. Is there any way to configure the new tank to not overheat the house?
Thanks you,
Pierre
