Thermogroup Thermonet Undertile 9m2 1350W Underfloor Heating Kit with Thermostat 111518T
The kit includes the heating mat, programmable thermostat, floor temperature sensor, sensor conduit, fixing tape and cable monitor, providing the essential components required for installation. Pre-spaced heating cables are secured within a self-adhesive mesh, helping to streamline installation while promoting even heat distribution throughout the room. The included thermostat allows for precise temperature control, making it easy to tailor comfort levels to suit daily routines.
Engineered with Thermogroup's TwistedTwin cable construction and LayFlat Technology, Thermonet is designed to support efficient installation and dependable performance. The wire-side-down configuration helps protect the heating cable during installation, while the low-profile design integrates neatly beneath tiled surfaces for a discreet and effective heating solution.

LayFlat Technology
Thermonet combines a slim 3.5mm TwistedTwin cable, self-adhesive mesh and low-profile cold tail connection. This LayFlat design reduces tension within the mat, helping it sit flatter for a smoother installation process.

Self-Adhesive Mesh
The integrated self-adhesive mesh secures the heating mat to the substrate during installation. This helps maintain consistent cable spacing across the floor, supporting even heat distribution and simplified floor preparation.

Durable Cable Construction
Built with a robust fluoropolymer coating, continuous armoured earth sheath and multi-strand twin conductors, Thermonet is engineered for dependable operation in underfloor heating applications where reliability and protection are essential.

Suitable for Multiple Floor Finishes
Beyond tiled floors, Thermonet can also be installed beneath engineered timber, vinyl and carpet when used with an appropriate self-levelling compound, providing greater flexibility across a variety of interior spaces.
