Thermonet 150W/m² undertile heating kits ship complete with everything needed for installation except insulation: the Thermonet 150W/m² mat, a programmable thermostat (5220A), floor temperature sensor, sensor conduit, fixing tape, cable monitor (6025), installation guide and warranty form.
The mat uses 3.5mm TwistedTwin cable on self-adhesive mesh with a low-profile cold tail, a construction that neutralises tension so the mat lays flat and installs easily. A tough fluoropolymer coating, continuous armoured earth sheath and multi-strand twin conductors deliver a robust, long-lasting cable with zero electromagnetic field.

Highlights
Lifetime Warranty: Thermonet Underfloor Heating systems, made in the United Kingdom, include a lifetime warranty, with a 3-year warranty on Thermostats.
TwistedTwin cable construction: The stress-free cable construction creates a longer-lasting heating cable with zero electromagnetic field (Zero EMF).
Full self-adhesive mesh: The self-adhesive mesh holds the Thermonet matting to the substrate for installation, self-levelling, and tile fixing. It ensures consistent cable spacing across the floor for even heat distribution.
Heating cable protection: Thermonet is installed wire-side-down, protecting the heating cable from damage during installation via the hard-wearing mesh layer.
Minimal height build-up: The matting system is 3.5mm thick with a low-profile cold tail of 4mm, which is typically concealed within the tile adhesive layer.
Works with multiple floor finishes: Thermonet is suitable for tiled floors, as well as engineered timber, vinyl, and carpet floors when installed with a 10mm layer of self-levelling compound over the Thermonet 150W mat.

Compatibility
Thermonet is commonly installed under tiled floors. It can also be used under engineered timber, vinyl and carpet floors by including a layer of 10mm self-levelling compound over the Thermonet 150W mat.
Warranty
Lifetime warranty on Underfloor Heating and 3-year warranty on Thermostat.
Thermonet 150W is designed to be installed above the screed, just in the tile adhesive. It is suitable to be installed in screed up to 20mm thick, but for screed more than 20mm thick an in-screed heating system such as Thermonet 200W is required.
Should underfloor heating be installed below or above the waterproofing?
To ensure a fully waterproof substrate it is recommended to lay the floor heating over the waterproofing. In a screed application, where the waterproofing is on top of the screed, an in-screed system can be laid before the waterproofing.
Is underfloor heating safe to be installed in the shower?
Providing the shower floor is tiled like the rest of the bathroom floor, all of Thermogroup's underfloor heating systems are suitable for installation in the shower area. The cable has an IP68 rating and a continuous earth braid the full length of the cable.
What is the difference between Thermonet 150W and Thermonet 200W?
The difference is the wattage per square metre and the application. Thermonet 150W is designed to be installed directly under tile, just in the tile adhesive, while Thermonet 200W is designed for installation beneath a screed.
