[Equest-users] Steam Heating plus Domestic

[Dane Heimerman]

Hi there,
I'm trying to model an old building with an one-pipe steam heating 
system. One unique thing about the system is that a heat exchanger in 
the steam boiler heats a storage tank for domestic hot water. I haven't 
found a way to connect the domestic loop to the steam boiler to prove 
how inefficient this system is. I'm expecting that the boiler would run 
much less if the systems were separated, but I need a way to show this. 
Any ideas on how to connect the two loops would be appreciated. My other 
question is, since this building has no air-side HVAC, what system 
should I use to heat the zones? Right now I'm using a 
'heating/ventilating' system, forcing the air flow to zero in all the 
zones, and turning on baseboards attached to the steam loop. Is that the 
right way to do it?

Thanks,
