Hello All, I am trying to simulate a storage tank Type4a for domestic hot water (heated by the air-water heat pump) which is connected to the building Type56 (active layer). I have a problem with connection of those two components especially with the return from the active layer to the tank. Can anyone advise me how can I create the new connections between Type4a and building in order to create proper circuit? I will appreciate any kind of help. Sincerely Wojciech Malik |
