Good luck mate ... If the custard had no bother before you landed then it's something to do with the conversion... Quiz them a bit more before you do to much drastic stuff ...
what a day removed part of the bathroom floor and the pipe boxing in the bathroom also part of the kitchen ceiling. never seen anything like the piping i found.old 28mm circs had been cut and capped above a tee the 22mm from the tees went to the bathroom radiator thus bathroom rad hot when hw on.found the cyl circs piped in 22mm both on the old rad flow like a one pipe radiator but system was a 2 pipe - customer said it took hrs for water to get hot. i am still amazed how the old boiler ever worked.the only thing i am worried about now is how reliable the danfoss rf cylinder stat is.
