Like other systems, you may face some issues with your radiant floor heating system. A broken wire is the most common problem. One day you wake up and realize that your heating system is not functioning anymore. You need not give up, as your heating system can still start working. The repairing process is quite simple, so you don’t need to be concerned. The hardest part of dealing with a broken wire is to tracking the section where the wire is broken.
The initial step in the identification of a broken cable in floor heat system is to contact the professionals. Most professionals offer their troubleshooting toolkit on rent. What is included in the troubleshooting toolkit? Usually, a toolkit includes a variable AC transformer, a dielectric strength tester, a time delay reflectometer, a dielectric strength tester, and a multimeter. Other tools are splice kits that can help you fix the broken wire after tracking it. You will need a thermal imaging camera to help you see through the tile.
Process of Identifying a Fault
It is very straightforward to find a fault in a floor heating system. The first step to detect a fault entails is to take the Ohms readings. Such readings can be obtained on the floor circuit. If you notice the readings are open from one core wire to the other or infinite, it is obvious that the wire is damaged at some point. On the other hand, if you realize sheathing Ohms readings between the core wire and the ground, you may have a short circuit.
You can narrow down the area where the wires are broken with the help of a time delay reflectometer. The gadget measures the length of the damaged wire and reports the findings to you.
Using the Thermal Imaging Camera
You have to ensure that the space is as dark and cool as possible when using a thermal camera. It helps you to have a clear picture of the heated cable through the tile. If you want to use the device in during the shading time, make sure to cover the windows of the room with a dark cloth or curtains. In this way, the impact of the light on the surface can be eliminated.
Dielectric Strength Tester Process
This process should only be performed by a qualified technician. This process involves sending a high voltage ranging between 400 and 6000 volts via the core wire. The purpose of this process is to copy the behavior of a sparkplug, for this, it passes current across the ground shield of the flooring. This requires numerous cautions which are only be carried out by a qualified person.
