Our 65W/m² electric underfloor heating mats are ideal for very well insulated properties or developments with a lower power requirement.

These low output mats are more commonly used in large new-build or change of use projects where a restricted power supply means that a low output electric heating system is vital as the overall Ampage of the system needs to be as low as possible. Recent Heat Mat projects have included retirement complexes, apartment blocks, a luxury hotel and a large Passivhaus all using our 65W/sqm mats to provide sole source heating.

65W mats are often used in energy-efficient new builds, Passivhaus properties or eco homes where a low output system will easily heat rooms. 65W mats can be used as sole source heating or support other forms of heating in a property.

65W heating mats are economical to run over larger areas due to their lower power consumption. And a lower output system reduces the likelihood of problems caused by thermal blocks.

Heat Mat Advanced Cable Design

What are the benefits of installing 65W/m² underfloor heating mats?

  • Cost effective solution for energy efficient homes
  • Lower power consumption required
  • Lower loading required
  • Easy to install
  • Low running costs
  • Designed and made in Denmark
  • Covered by our lifetime warranty

Underfloor heating mat systems react faster and are more energy efficient when used with an intelligent thermostat timer and are laid onto thermal insulation boards.

Simple and speedy installation

Heat Mat electric underfloor heating mats are incredibly simple to install, and in large areas can take one third of the time a loose heating cable would take to fit. The mats can be cut and turned to ensure that they fit the room perfectly, and for particularly complicated areas the cable can be stripped from the mat and laid as a loose cable. The mats readily affix to the floor with three strips of double-sided tape, and the strong fibreglass mesh above the cable ensures it is protected during tiling.

Suitable for nearly any floor covering

If you are unsure of the final floor covering, 65W mats can be fitted and then covered by a flexible levelling compound allowing a huge range of final floor coverings to be fitted on top including tiles, carpet, wood and vinyl.

Energy efficient solution

65W heating mats are extremely efficient at converting electricity into heat. They can be powered from renewable energy sources. Our NGTouch thermostat has energy saving features and displays usage in £'s and pence helping to ensure your system runs efficiently.

Lifetime guarantee

We manufacture our high-quality heating mats and cables in Denmark and Germany. Our electric underfloor heating mats are supplied with a Lifetime Warranty.

Innovative heating cable technology

Over the last three decades Heat Mat have worked to continuously improve the design of their cables and mats to ensure their safety and longevity. This unique combination of technologies means you get a safe and fast to install system without sacrificing quality. Only Heat Mat’s systems include this combination of technologies:

  • Litzer Wire Technology – multiple heating elements are spun together to provide superior strength in a very flexible heating wire
  • 200°C Fluoropolymer Protection – super-high temperature fluoropolymer insulation surrounds the heating elements and provides superior protection against overheating and physical damage
  • Kevlar Anti-stretch Cable – Kevlar strands run through the centre of the heating cable preventing it from being stretched and damaged during installation
  • 100% Earth Shield – an aluminium safety shield wraps the entire heating cable to ensure the system is instantly shut down if damaged. The shield also enables the cables to hold their shape when being installed
  • Anti-crush Cable Jacket – the high quality PVC cable jacket provides unrivalled protection against crushing and cutting damage during installation
  • 100% Shielded Coldtail – the entire coldtail is shielded continuing the 100% electrical protection seen on our heating cable
  • Cut & Turn Mat System – the cut-and-turn systems allows mats to be turned back on themselves multiple times during fitting, meaning less mats are required ensuring a far smoother installation
  • Zero-float Mesh – the mesh terminates at the last row of tape rather than continuing to the ends of the cable, so none floats up when covered in levelling compound or screed
