I'm trying to troubleshoot our central heating system in our residential house. Our house was built around the 90s and I've found that we use Radiant Floor Heating. The plans I've obtained from the public records are simply structural layouts and contain no plans for how the central heating was installed. I've asked and I've been told that the contractors just take care of that without really following an architectural or engineering plan.
So now I'm simply finding out the routing of the Radiant Heating System. I know on the floor, they run as PEX tube, so there's no way of detecting them. Unless we were to dismantle the flooring. The copper pipes, however are a different matter. I gather that an experienced contractor can predict where they are and they can even be detected by certain tools. Tools much like a stud finder.
So is it doable? Finding the copper pipes? What's the best way of doing it?
Also, I believe that the copper pipes usually run through the walls, is this true?
