I just recently bought a home with brick floors and a boiler run hydro radiant heating system on a slab. When replacing some of the bricks, my flooring guy discovered that the pipes were not laid deeply enough and therefore the system is not up to code. This is something I would have to disclose and be liable for if and when I sell the property. Do you recommend digging up the floors and reinstalling the system? What are my options? What kind of expense for a 2500 square foot home? A new boiler is also needed.
