The cable is 2mm thick, which is the thinnest currently available on the market.
Yes, a thermostat is required to regulate the temperature and protect your flooring from overheating.
Yes, the Teflon-coated dual-core cables are suitable for bathrooms and en suites when installed according to local electrical regulations.
Consult the thermostat manual for specific error definitions, often related to the floor sensor connection.
Verify that the circuit breaker is on and that the thermostat is set to 'Manual' or 'Schedule' mode with the target temperature higher than the current floor temp.
Check that the mat was laid flat without overlaps and that the adhesive covers the cable fully to ensure proper heat transfer.
Installation involves rolling out the mat on a clean, level subfloor. Use a flexible tile adhesive to secure the mesh, then embed the heating elements before laying your final floor finish. The system is compatible with most standard floor tiles. Ensure the floor sensor (usually included with the thermostat) is installed in a conduit between two cable runs to allow for future maintenance if needed. Care should be taken never to cut or shorten the heating cable itself, as this will compromise the system. Once installed, allow the adhesive and grout to cure fully according to the manufacturer's instructions before powering on the system for the first time.
