Flexel ECOFLEX 160W/m² Loose Underfloor Heating Cable

Flexel ECOFLEX 160W/m² loose underfloor heating cable is a professional electric underfloor heating solution designed for installers who need greater flexibility than a standard heating mat can provide. Supplied by Eco Friendly Heating & Flooring, this loose cable system is ideal for tiled rooms where the layout includes corners, fixed furniture zones, sanitary ware, kitchen units or other obstacles that make a pre-spaced mat less practical.

Because ECOFLEX is supplied as a loose cable only option, it allows the installer to heat more of the usable floor area and shape the layout around the room rather than forcing the room to suit a fixed mat. This makes it a strong choice for bathrooms, kitchens, conservatories, en-suites and other awkward-shaped spaces.

The 160W/m² output is well suited to areas that need responsive floor heating and a stronger heat output than low-wattage systems, particularly where rooms have more exposed walls, colder floor constructions or greater overall heat loss.

Why Choose ECOFLEX Loose Cable?

Loose cable underfloor heating is often the best option when room shape matters. Instead of being fixed to a mesh backing, the cable can be routed more precisely to suit the available floor area. This helps installers work around fixtures, maximise heated coverage and create a more tailored floor heating design.

• Flexible layout for shaped or obstacle-heavy rooms
• 160W/m² output for stronger floor heating performance
• Ideal for tiled areas such as bathrooms, kitchens and conservatories

Best Rooms for ECOFLEX 160W/m²

This system is particularly useful in:

• Bathrooms with toilets, basins or fitted furniture to work around
• Kitchens with units or island layouts
• Conservatories and glazed extensions
• En-suites and utility rooms
• Irregular floorplans where mat systems are less efficient to fit

If your room is more open and regular in shape, a heating mat may reduce fitting time. For comparisons, read our StickyMat & EcoFloor Heating Mats Guide.

Installation & Build-Up Advice

ECOFLEX should be installed over a suitably prepared and insulated subfloor and used with the correct thermostat and floor sensor. Good insulation beneath the heating cable helps reduce downward heat loss, improves warm-up times and supports lower running costs.

Running Costs & System Comparisons

Like any electric underfloor heating system, real running costs depend on room size, insulation, thermostat settings and how long the system is used each day.

FAQ’s

When is loose cable better than a heating mat?

Loose cable is usually better when the room has an awkward layout, fitted obstacles or narrow areas where a standard heating mat would leave too much unheated space.

Is ECOFLEX 160W/m² suitable for bathrooms?

Yes. It is a strong option for tiled bathrooms and en-suites, especially where you need to work around toilets, basins or fitted units.

Can ECOFLEX be used in a conservatory?

Yes. The 160W/m² output is well suited to conservatories and other spaces with greater heat loss where stronger floor heating is beneficial.

Does this system need insulation underneath?

Yes. Suitable insulation beneath the cable is strongly recommended to reduce downward heat loss, improve warm-up speed and support lower running costs.

Do I need a thermostat and floor probe?

Yes. A compatible thermostat and floor sensor are essential for safe control, efficient operation and protecting the floor build-up.

Is this a DIY underfloor heating system?

No. ECOFLEX is sold as a professional installer product and should be fitted by someone experienced with electric underfloor heating systems, with final electrical connection completed by a qualified electrician.
