<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>The
easiest way is to use two zones, but if the thernostat is in the hall, maybe
you should include that zone as well? You can also consider using CONTAM or
COMIS to calculate air exchange between the zones, although this makes it more
complicated.</span></font> <br>
<br>
<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>You
can have one emitter for each zone. To represent parallell heating circuits,
just split the total flow from the heat pump using a diverting valve component
(Hydronics library) into one stream for each emitter and then, after the
emitters, combine the streams again using a mixing valve component and connect
it back to the heat pump.</span></font> <br>

<p class=MsoNormal><font size=3 face="Times New Roman"><span
style='font-size:12.0pt'>I am modelling a 2-floor domestic property.
The 2 floors are connected by an open hall, stairs and landing. A
thermostat is located in the hall.<br>
<br>
A single heating system (GSHP) will need to supply heat to both floors (under
floor heating or low temperature radiators.)<br>
<br>
What is the easiest way of modelling this; I'm thinking:<br>
<br>
1) Use 2 zones; One for upstairs and one for down stairs.<br>
2) Each zone has an emitter.<br>
3) Each emitter is a load on the same heating system. Is it easy to
represent parallel heating circuits from a single heat source? What
components should I be looking at?<br>
<br>
Any comments welcome. <o:p></o:p></span></font></p>
