I did a heat loss calculation and my room requires an 18 section Sunrad. The home owner wants to put custom wood covers in front of the Sunrad (see pics). How many BTU would you add because of these custom covers?

Your really killing convection with that design.
Maybe you get lucky and the system is oversized.There was an error rendering this rich post.

looks like a pretty restrictive grill? Sometimes the manufacturers of screen give you the "open area" % on various screen material.
I get special metals from this Chicago area company from time to time, they give you the open area number.Bob "hot rod" Rohr
