How do you locate a ground fault?
To locate a ground fault, look for continuity to ground on each circuit. This new analog ohmmeter will show infinite ohms when the conductor is not exposed to an earth ground. If the insulation is compromised and/or the copper is directly connected to ground the ohmmeter will indicate 0 ohms.
Why is my in-floor heat not working?
The main cause of problems with in-floor radiant heating systems is a defect in the wall thermostat. When your thermostat is defective, it will keep the heating from working properly. Thermostats that fail to close properly cause the room to be cold at all times.

A ground-fault occurs when there is a break in the low-resistance grounding path from a tool or electrical system. The electrical current may then take an alternative path to the ground through the user, resulting in serious injuries or death.
What is the most efficient way to run underfloor heating?
For an efficient system and quick response times, set your underfloor heating temperature to 16°C in “off” periods. This will result in a quicker warm up time as the heating system needs to supply less energy.
How do you find a fault in electric underfloor heating?
UNDERFLOOR HEATING FAULT FINDING We can detect a faulty heater by using a thermal imaging camera and specialist testing equipment which is used to locate the exact point of fault. The damaged cable or pipe is then accessed by lifting the floor for that area only and fixing the damaged heater.
