    Adding wall over existing radiant floor heat possible?

    Looking at buying a house that has laundry in garage with radiant floor heating everywhere. Is there a way to positively identify where the Pex tubing is placed so that I could have a contractor build an enclosed room without damaging the tubing? Don't want to chance nailing or screwing through the in floor water lines.

    Infrared imaging

    will pinpoint it if you let the slab cool down for several hours on a cold day and then fire up the system.

    No screws, just glues...

    Use only a good grade of construction adhesive to anchor your sole plates to the floor, but that's the LEAST of your problems. If you isolate the room, and it has different loss/gain characteristics than the original room, you may find yourself back here look for additional answers. Make sure the room has the same gain (floor coverings critical) and loss factors (not isolated to the middle of the house where no heat loss is occurring) or you WILL be in trouble.

    And that is only the beginning…. Then there is solar gain, flywheel /mass momentum, ventilation etc etc etc… The piping patterns may not be conducive to sub zoning.

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.

    Like Mark said

    Safest bet for a novice to hydronics, and infrared. It's a partition wall any way.
