Luis,
If you have a modulating boiler it's probably not necessary to have a storage tank. Some people put one in for thermal stability but I've seen lots of cases where it's just the boiler. But here's the beauty of TRNSYS - try it. If it's not behaving well then try adding a tank and see if it behaves better. Because it's emulating the real system, and the models are based on physics, the simulation should behave like a real system.

Hello everyone,I want to simulate a central heating system (wet system) for a church. A gas boiler should heat the water that will be distributed through the radiators. In total there are 10 radiators in the same and only zone. I can use type 56 (multizone), type 700 and type 1231, and type 3d for the pumps right? There is no need for domestic hot water, just heating water.Is this enough for my situation?1x boiler10x radiators2 circulating pumps1 thermostat/control for activate heatingI just want to know if a storage tank is needed just for central heating. Is it typical for this application?Thank youBest regards,Luís
