[EnergyPlus_Support] Boiler is not working (Solar collector + Storage tank + Gas boiler + Floor heating) [2 Attachments]

["Novak Nikolic lepinole@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Dear,

I am trying to simulate system that consists of solar collectors, storage tank (nominal capacity = 0), gas boiler and floor heater. I am wondering is it possible that gas boiler (boiler: hot water) reheats the water from the storage tank if there is not enough heat from solar collectors. I simulated the mentioned system, there is no errors but the results point out there is no boiler (gas consumption = 0). Also the air temperature in the rooms are below setpoint temperatures during the hole run period. In the attachement is the list of used objects and SVG diagram.
