Description
Protect and Future-Proof Your Underfloor Heating Cold Tail
ThermoSphere Flexible Conduit is a corrugated protective conduit used to house the cold tail power lead and floor sensor cable of an electric underfloor heating system as it runs from the heating element, through the screed or chase, to the thermostat. Running the cold tail through conduit protects the cable during installation and allows it to be withdrawn and replaced without lifting tiles or flooring if it's ever damaged.
Key Benefits
- Protects the cold tail and sensor cable during screeding and floor finishing
- Allows the cable to be withdrawn and replaced without disturbing the floor
- Flexible corrugated design routes easily around corners and through chases
- Available in 2m and 3m lengths to suit different room layouts
Applications
Used by electricians and underfloor heating installers to protect the cold tail connection and floor sensor cable where it passes through screed, chased masonry or under floor finishes on its way to the thermostat. Suitable for bathroom, kitchen, wetroom and living space underfloor heating installations using ThermoSphere heating cable, mesh or foil systems.
Performance & Features
The corrugated wall gives the conduit flexibility to route around obstacles while maintaining its shape and resisting crushing under screed or floor finishes. Running the cold tail and sensor cable through conduit rather than direct into the screed makes future maintenance straightforward, as damaged cables can be drawn out and replaced through the conduit run.
Compatibility
Suitable for use with all ThermoSphere underfloor heating cable, mesh and foil systems, and their cold tail leads and floor sensor probes. All electrical work should be carried out by a suitably qualified electrician in accordance with the relevant local safety regulations and standards.

FAQs
What is this conduit used for?
It protects the cold tail power lead and floor sensor cable of an electric underfloor heating system as it runs through screed or a chase to the thermostat.
Why not just embed the cable directly?
Running the cable through conduit means it can be withdrawn and replaced if ever damaged, without needing to lift tiles or flooring.
Which length do I need?
Choose 2m or 3m depending on the distance from your heating element to the thermostat position — measure the run and allow a small amount extra for routing.
Can it be chased into a wall as well as a floor?
Yes, it's flexible enough to be routed through a floor screed or chased into a wall on its way to the thermostat.
Is it compatible with all ThermoSphere heating systems?
Yes, it's suitable for use with all ThermoSphere underfloor heating cable, mesh and foil systems and their cold tail leads and sensor probes.
Who should install this?
All electrical work, including the cold tail connection, should be carried out by a suitably qualified electrician.
