[TRNSYS-users] Storage Tank

[Jeff Thornton]

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.

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.
