When you need reliability, fit ThermoSphere Ultimate® heating cable!

The only underfloor heating cable to combine TwistedTwin cable, and in-line joint technology in one award winning package (2023 Flooring Innovation Winner).

When installing electric underfloor heating, you hope never to go back. ThermoSphere Ultimate® is quick and easy to install, plus it’s the most reliable underfloor heating cable on the market. That’s because ThermoSphere Ultimate combines a TwistedTwin cable, and in-line joint technology. This removes the risk of damaging the cable during installation, as cutting into the membrane and substrate is no longer required.

For total peace of mind

With guaranteed reliability there's little to no chance of the cable failing when installed correctly. We’re so confident about this that should the underfloor heating system fail in the first twelve months of installation because of a manufacturing fault, we will not only replace the system, we'll also replace the floor covering too (available after confirmation of successful warranty registration). So, sit back and relax because we’ve got you covered.

Speed up installation and reduce risk

Unlike most electric heating cables, there's no bulky hot/cold joint that needs cutting into the floor. This transforms installation into a one-step process, making it faster and easier while significantly reducing any chance of accidently damaging the cold tail joint during installation. No cutting also means the membrane’s waterproofing layer stays intact.

Use it with any membrane mat

ThermoSphere Ultimate is compatible with all decoupling membrane mats. This means you can use your preferred brand of decoupling mat with the easiest to install and most reliable heating cable.

Thermosphere ultimate underfloor heating cable can be used with any underfloor heating matting.

ThermoSphere Ultimate is the ONLY heating cable to combine in-line joint technology with TwistedTwin cable construction. This makes it the most robust 'in-line joint' heating cable you can use – giving quick quality workmanship for your customers.

What is ThermoSphere Ultimate

Our in-line joint membrane cables do not have bulky hot/cold joints that are created after the primary manufacturing process. They are the same thickness from the end termination to the cold tail that connects to the thermostat. This makes them stronger, more reliable, and easier to install.


Why is ThermoSphere Ultimate heating cable better?

Our in-line joint membrane cables make installation easier because installers don’t have to cut into the membrane, insulation board, or chase out concrete. Cutting and chasing also makes joints the most common point of failure during installation. Removing the bulky joint removes that risk too.


How easy is it to install ThermoSphere Ultimate?

Very. You can simply press the cable into the membrane mat, covering the whole of the heated area, and you’re done. Because there are no bulky joints or thicker cold tail cables, installation is a one-step process. The membrane and cable are automatically flush and ready for tiling.


What heating cable lengths are available?

There are four new cable lengths: 42m, 55m, 90m and 175m. But all the existing lengths will become in-line joint too, which means you’ll have a cable for every project.
