You won't see it, but you'll feel it
Thermonet features 3.5mm TwistedTwin cable, self-adhesive mesh and our low-profile cold tail connection cable. These features make up what we call LayFlat Technology because this combination neutralises tension in the finished product and makes Thermonet easier to fit.
Safe, simple and reliable
Thermonet underfloor heating cables have a tough fluoropolymer coating on the outside and internal conductors, a continuous armoured earth sheath and multi-strand twin conductors.
The conductors as twisted together to eliminate electromagnetic field (EMF) and neutralise the stress, expansion and contractions of the cable along the entire length; resulting in a more robust longer lasting cable.
Lifetime Warranty
We are so confident of the quality of our Thermonet Underfloor Heating systems, made in the United Kingdom, that we give each system a warranty that lasts a Lifetime with 3 year warranty on our Thermostats.
TwistedTwin cable construction
The unique stress free cable construction creates a longer lasting heating cable with zero electromagnetic field (Zero EMF).
Full self adhesive mesh
The self-adhesive mesh speeds up installation by holding the Thermonet matting to the substrate for easy self-levelling and tile fixing. It also ensures an even and consistent cable spacing across the floor to ensure an even heat.
Heating cable protection
Thermonet is installed wire-side-down which means the heating cable is protected from damage during installation by the hard wearing mesh layer.
Minimal height build-up
Utilising innovative extrusion processes provides real ‘lay flat’ technology that makes installing Thermonet easy. The matting system is only 3.5mm thick with a low profile cold tail of only 4mm thick which is typically concealed within the tile adhesive layer.
Works with multiple floor finishes
Thermonet is commonly installed under tiled floors. Many people don't realise that you can also bring the warm feeling to an engineered timber, vinyl and even a carpet floor by including a layer of 10mm self levelling compound over the Thermonet 150W mat.

Frequently Asked Questions
Can Thermonet 150W be installed below a screed?
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 that 20mm thick an In Screed Heating system such as our Thermonet 200W is required.
Is Underfloor Heating safe to be installed in the shower?
Providing that the shower floor is tiled (not a shower base) 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 IP (Ingress Protection) rating of IP68 and a continuous earth braid the full length of the cable. This ensures it is safe should the cable come in contact with water and gives you the assurance of safety in the unlikely event of install damage. For further protection we recommend that you do not end the heating system in the shower area.

For further protection we recommend that you do not end the heating system in the shower area.
Can Underfloor Heating be installed up the side and on top of a shower seat?
All Underfloor Heating cable must be covered by a cement-based product and cannot operate in a void. Therefore, provided that the shower seat is tiled like the rest of the bathroom and all cable is covered by a cement-based flexible tile adhesive, then it is perfectly safe to install the heating on a shower seat.
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.
Why would I use a matting system over against a loose wire system?
The matting system is self-adhesive and has all the heating cables pre-spaced which makes installation quicker and easier than with a loose wire system. Having the heating cables pre-spaced also ensures that the heating is not patchy like can sometimes occur with loose wire.
What is the best Underfloor Heating system for my application?
If you are unsure which floor heating system best suits your needs or daunted by the many options and offerings on the market, Thermogroup's online underfloor heating system selector tool can help you make the best decision. Our underfloor heating selector takes you through a simple four step process to determine the most suitable underfloor heating system for your individual application then also lists out all the products required to get the job done, so you can be assured that you will have everything required when it comes to installation. If you have any requirements outside of those specified on the tool do not hesitate to contact us to discuss your requirements.
What is the difference between Thermonet 150W and Thermonet 200W, and which system should I choose?
The difference between Thermonet 150W and Thermonet 200W is simply the wattage per square metre, and the application for which they are used. The Thermonet 150W is designed to be installed directly under tile, just in the tile adhesive, whilst the Thermonet 200W is designed for installation beneath a screed as the higher wattage makes it more effective in heating through this screed. For a further comparison between the two systems, please view our article on which is more effective, or to determine which system is right for your application try our Heating System Selector.
What are the rough in or first fix requirements for Underfloor Heating and a Controller?
When roughing in for our Underfloor Heating and the controller, the electrician will first need to bring mains power to the Thermostat location. The electrician will then also need to run two 20mm conduits from the Thermostat position down to the floor, for the Underfloor Heating Cold Tail and for the Floor Sensor. For further information and a visual representation, please view our Conduit Requirements download.
