Hello all, I am modelling a HVAC system that uses geothermal as primary source of heating and cooling. However, it uses a boiler for winter peak and a cooling tower for summer peak hours. Both of these uquipments are connected to the geothermal loop. Can anyone please give me some idea as to how I can model this system. Before, I tried connecting a boiler to GSHP loop in the detailed mode but eQuest did not allow me to do that. Thanks for your help. Regards, Hassan
