I have a raised porch that I may expand into a sunroom. It will be about 14 X 16 feet and have large windows on three sides. The current floor is concrete -- I can get underneath to insulate. I'll put ceramic tile on top of the concrete. I am in Maryland.
Here's my question -- is this a good application for a hydronic radiant system? Does it change the calculation if i put in a cathedral ceiling? What's the ballpark cost for such a system, or where can I go to calculate the cost?
