Superior product design

harmoni electric underfloor heating mat

All Harmoni underfloor heating mats and cables are manufactured to the highest standards using quality materials and come with a lifetime warranty.

The backing mesh is made of strong, durable nylon with a self-adhesive backing. This allows for a quick, secure installation and avoids problems due to the mat floating or moving in the tile adhesive.

Stitched cables

harmoni electric underfloor heating mat

The underfloor heating cables are stitched to the durable backing mesh with a special heat resistant thread. This ensures the element spacing remains uniform, guaranteeing an even distribution of heat and eliminates the opportunity for cold spots, which is a common problem with lesser quality mats.
