Thermogroup Thermonet Undertile 9m2 1350W Underfloor Heating Kit with Dual Thermostat 111518TD
At the heart of the kit is the Dual Thermostat, offering the flexibility to independently control the underfloor heating system alongside an additional bathroom appliance, such as a heated towel rail, from a single controller. Individual scheduling allows each function to operate according to daily routines, helping to create a more comfortable and personalised bathroom experience. The complete kit includes the heating mat, programmable thermostat, floor temperature sensor, sensor conduit, cable monitor and installation accessories required for a streamlined installation.
Engineered for use beneath tiled floors, the Thermonet 150W/m² system features a slim 3.5mm profile, IP68 protection rating and floor-sensing temperature control for dependable performance in bathrooms and other tiled living spaces. Manufactured with durability in mind and supported by a lifetime warranty on the heating mat, it offers a practical solution for homeowners seeking the everyday luxury of warm floors underfoot.

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.
