Infrared camera thermography is the only non invasive way to locate underfloor heating pipes or electric wires. The infrared camera will locate leaks in the heating pipes and will find shorts or resistance spots in the electric underfloor heating.
Underfloor heating pipe leaks are extremely frustrating because water always follows the path of least resistance. This means that the place where water accumulated is not necessarily where the source of the leak is. This is where an infrared camera can help. It works both indoors and outdoors and will often show the exact source of the leak.
