[TRNSYS-users] How to start a hotwater circulation simulation

Daniel - 

Can you be a little more specific about your problem?
Just saying it doesn't work when you add a building model does not give
us much to go on when trying to help you solve the problem. 

Regards,

So I started to create a very simple network with a water tank (type
4a), a pump (type 114 e.g.) and connect those with a few pipes (type
31), tee-piece diverter and mixer (type 11d/f)...So far so good, even
though the result is meaningless, it worked.

Has anyone ever had contact with this kind of simulation (hot water
circulation etc.)? If so, how did you start?

stratified fluid tank (type 60) and maybe a solar system which feeds the
tank with a lower temperature as well.
