Eco Friendly Heating Loose Wire Underfloor Heating System

The Loose Wire Heating System is designed for flexibility and performance — perfect for irregularly shaped rooms or spaces with many fixtures and fittings. The ultra-thin heating cable is easily laid around corners, fixtures, and curves, giving you full control over spacing and heat output for a perfectly balanced, energy-efficient result.

This system works beautifully beneath ceramic and natural stone tiles, delivering consistent warmth and comfort across the floor surface without raising the floor height.

Ideal For

  • Bathrooms, kitchens, hallways and living spaces

  • Small or awkward spaces where heating mats don’t fit

  • Eco-conscious upgrades aiming for better comfort and lower energy use

If you’re working with regularly shaped rooms, our Sticky Mat System provides a quicker installation option. For tile protection, consider the DCM-PRO Heated Decoupling Mat, and for non-tiled floors like laminate or carpet, our Foil Heater System offers a completely dry, self-levelling-free installation.


Flexible, Efficient Design

The Loose Wire System comes as a complete kit, making installation simple and straightforward. Each kit includes:

  • Ultra-thin 1.8mm dual-core heating cable – the thinnest on the market

  • Primer – for preparing wooden subfloors

  • Fixing tape – to secure the wire layout

  • Foam roller – for smooth application

  • Step-by-step installation manual

At only 1.8mm thick, the heating cable doesn’t raise your floor height, making it ideal for renovations or projects with limited space. Because the system installs directly with tile adhesive or a thin self-levelling compound, there’s no need for a full screed layer — saving both time and resources.

Once the cable is laid, your chosen floor finish can be installed right away, making the Loose Wire System a fast, efficient, and eco-conscious heating solution.


Reliable Warmth for Every Room

Whether you’re heating a bathroom, kitchen, or hallway, the Loose Wire Underfloor Heating System can be used as either a primary or secondary heat source, fully compliant with current Building Regulations.

For best results, always confirm that you have the correct size and number of cables for your project before installation. If you’re unsure, our friendly team at Eco Friendly Heating and Flooring is happy to help you choose the right setup for your space.
