Default Radiator

Hello, I'm trying to simulate the flow inside a room using those wall radiators as a heating system. The problem is that I don't want to mesh the detailed geometry of the radiator since it has sheets of about 1mm. I'm trying to simulate it as a rectangular prism, but the problem is how to have the same surface temperature and heating power as the real case, since the area is not the same. If I input the temperature, the heating power is subdimensioned, if I impose the power, the temperature will be to high.

I tried to solve it as a porous media, but then there is no way of saying the area/volume ratio. Any suggestions? Is there a way to impose the heat transfer coefficient at the surface by a UDF so that both the temperature and the heating power will be the specified?

thank you
