[EnergyPlus_Support] Low Temp Radiant System Inside Surface Temperatures

["Elreq" <tolteca33@xxxxxxxxx>]

Dear Forum,

I have the following problem:

I am modeling an underfloor heating & cooling system using the object:
Low temperature radiant system: constant flow. It works fine, but if I
select the surface under which the radiant tubing is embedded, in this
case a floor of a zone, and I see the inside temperatures, this are
not as high as they should be due to the hot water flowing through the
tubes. The temperatures increases when the heating rate increases but
I expect to see some temperatures around 28 degrees or so, but they
hardly get to 24-25. So then i do not know how to increase the
capacity of the system. Should I increase the flow rate? Or the tubing
lenght? I would really like to see that the temperatures in this
surface get higher.

Any advice greatly appreciated.
