Ecofloor In-Screed Heating Cable System - Electric Underfloor Heating 100W/m²

Eco Friendly Heating & Flooring supplies high-performance in-screed underfloor heating systems designed for modern construction projects. This 15W per linear metre heating cable is engineered for installation within screeded floors, providing an effective and economical solution for heating larger spaces.

Installed directly onto insulation and covered with a minimum 50mm sand and cement screed, the system delivers consistent radiant heat across the floor, making it ideal for new builds, extensions, and full renovations.

Why Choose This In-Screed Heating Cable?

Unlike surface-mounted systems, in-screed heating becomes part of the building structure. This allows it to deliver stable, long-lasting warmth while remaining completely hidden beneath the finished floor.

• Cost-effective heating for large areas
• Flexible cable layout for full coverage
• Compatible with all floor finishes
• Designed for long-term durability

Installation Overview

Correct installation is key to achieving efficient performance:

• Preparation: Install onto a fully insulated, clean, dry subfloor
• Laying: Position cable in even parallel runs with spacing to achieve desired output
• Fixing: Secure using fixing tape to maintain layout during installation
• Embedding: Cover with at least 50mm screed layer
• Important: Avoid installing beneath fixed furniture or permanent fixtures

Performance & Efficiency

In-screed systems are designed for thermal stability. While they take longer to warm up than surface systems, they retain heat for extended periods, helping to maintain consistent room temperatures with reduced energy fluctuations.

FAQ’s

Is in-screed heating better than heating mats?

It depends on the project. In-screed systems are better for new builds and large areas, while heating mats are quicker to install in smaller tiled spaces.

Can I adjust the heat output of this system?

Yes. The output can be adjusted by changing the spacing between the cable runs during installation.

Does the system need a thermostat?

Yes. A compatible thermostat and floor sensor are essential for controlling temperature and ensuring efficient operation.

Is insulation really necessary?

Absolutely. Without insulation, heat is lost into the subfloor, reducing efficiency and increasing running costs.

Can this be used in high heat-loss rooms?

Yes. This system is ideal for areas like conservatories or extensions where higher output is required.

Is the cable visible after installation?

No. Once embedded in screed, the system is completely hidden beneath the finished floor.
