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-shrand 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.

    Using Vario cable allows you to space the heating cables yourself to achieve a desired layout and heat output per m².

  • Advanced TwistedTwin heating cable

    Our superior advanced TwistedTwin heating cables are unique; you will find thinner cables, but you won’t find better quality

  • Strong bond to the substrate

    The adhesive used in the Vario fixing strip is a high-grab, pressure activated adhesive that bonds permanently to the substrate and the heating cable.

  • Ideal for irregular shaped areas

    The layout is totally flexible and can be designed to fit around furniture and fixtures in small or irregular shaped rooms.

  • Pre measured cable spacing

    The Vario fixing strip has pre measured 10mm cable spacing markers that remove the need to measure and mark your substrate, saving you time.

Frequently Asked Questions


What are the advantages and disadvantages of loose wire over a matting system?

Loose wire is designed for small awkward area as it is easy to place where needed and go around fixtures. However, in large open areas a matting system is recommended at it is a lost quicker and easier to install and having the heating cable all pre-spaced on the matting means there is less chance of having uneven heating across the room.

What is the optimum cable spacing for loose wire heating?

The ideal spacing between heating cables is 90mm. The minimum cable spacing is 40mm and the maximum spacing is 110mm. To calculate your cable spacing use the following formula:
Available Floor Space (m²) × 100  ⁄   Cable Kit Length (m)   =   Cable Spacing (cm)

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.

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.

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.

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.

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.
