Karol,<br>
I would use the active layer in Type56 to model the radiant floor
option. Type1231 is intended to model low-temperature hydronic
heat-distributing units such as radiators, convectors, and baseboard
and finned-tube units. There is guidance in the documentation on how
to choose values of the parameters. While your radiator doesn't have
tubes exactly, I would treat the vertical flow channels as pipes and
use an approximate diameter (or more ideally, the hydraulic diameter
of the flow channel)<br>
Kind regards,<br>
David<br>
