<font face="sans-serif" size="2"><span style="font-size: 10pt; 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 face="sans-serif" size="2"><span style="font-size: 10pt; 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 face="Times New Roman" size="3"><span style="font-size: 12pt">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. </span></font></p>
