<p>Habtamu,</p>
<p> That is the correct method. I usually define a gain in TRNBuild
that is called "QRADIATOR" and that sets the split between how
much of the gain is convective and how much is radiative. Although
we call them "radiators" usually about 80% of their heat gain is
convective. So my QRADIATOR has 0.8 set as its convective part and
0.2 set for its radiative part. Then in each zone, I select that
QRADIATOR gain and I scale it by the input value that comes from
Type1231. <br>
</p>
<p>If you are not seeing as much heat output as you expect from your
radiator recall that usually the design heat output assumes an air
temperature of about 10C. If you then try to maintain something
more like 20C in the zone then the radiator will not put out
anywhere near the design heat amount. It will put out measurably
less.<br>
</p>
<p>kind regards,</p>
<p> David</p>

<div dir="ltr">Dear David
<div>Hope you are doing well and safe. I appreciate your support
in answering all related questions in TRNSYS. I have tried to
type 1231 radiator for my two-store building type56 in order
to give a heating system for a room of 13*7*3.8m on the ground
floor, however, still, I am not sure enough on the result.</div>
<div>let me explain, some of the steps I followed to model the
system</div>
<div>1. I added Radiator as miscellaneous in TRNBuild gain/loss
and considering in the convective "1*input"</div>
<div>2. I connected each radiator output of "Heat Transfer" to
the type56 to Input</div>
