Why Thermonet

Thermonet® heating cables have a tough fluoropolymer coating on the outside and internal conductors, a continuous armoured earth sheath and multi-strand twin conductors.

Most cables on the market have multi-strand dual conductors but with TwistedTwin™ we offer more. Thermonet® and Vario® are the only underfloor heating systems in the UK to feature our unique TwistedTwin conductors. We twist them together to eliminate electromagnetic field (EMF) and neutralise the stress, expansion and contraction of the cable along the entire length.

This results in a more robust, workable, and longer-lasting cable superior to anything else available.

Fast-install LayFlat™ technology

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 and faster to fit.

Three heat output levels

Thermonet is available in three heat output levels for different situations.

Thermonet® BASIC 100W/m2 is an ideal additional heat source to take the chill off your floor in a retrofit application. However, in a well-insulated new build, Thermonet® BASIC 100W/m2 is capable of providing a primary heat source. Thermonet® EZ 150W/m2 can be used as a primary heat source in a well-insulated environment when covering around 85% of the floor space. This is the most popular output today.

Thermonet® EXTRA 200W/m2 is designed for areas such as conservatories that have high heat loss, or require faster heating. EXTRA systems do not necessarily get any hotter but reach operating temperature faster and are better able to cope with heat loss to the outside environment.

Low running costs

Every installation is different but as a rule of thumb, the annual cost of running Thermonet® EZ 150W/m² should be around £12 to £14 per m².
