Key Features of the 100W Devi Underfloor Heating Mats for Timber - DTIR-100

20 year guaranteeLead free
Flame retardedFully screened cable
Open self-adhesive mesh designExcellent value for money
4mm mat thicknessPremium well trusted brand

The DEVI underfloor heating mats for timber floors are developed for a variety of installations. Installation is made simple with the DEVIcomfort mat as they are ready to roll onto the floor.

DEVIcomfort Underfloor Heating Mats for Timber are an extremely high-quality, self-adhesive all-in-one mat with a tough red PVC outer sheath (non UV stable). It has been designed specifically for applying to a timber floor structure (i.e. floors raised on wooden joists).

Each mat has a cold lead which is an installation cable with solid conductors that allows for fast installation. By having a clearly visible connection, it minimises the risk of accidentally installing the heated cable by accident.

DEVIguard Warranty - The best in class floor guard warranty, DEVI Floor Guard warranty not only guarantees it's heating systems but also guarantees the floor in the unlikely event that the system cannot be repaired due to a manufacturing fault. Other manufacturers only offer product warranties which do not include the replacement of the flooring. This is DEVI's commitment to the quality of their product. Every single heating mat has been inspected which includes tests such as Ohmic resistance, high voltage and material controls.

Typical application areas

  • Indoor floor heating in domestic and commercial buildings
  • Very thin floors - perfect for renovating projects
  • Floors with a timber base
  • Tiled, vinyl or carpets top layer

We also have heated mats for concrete based floors and high output areas such as conservatories and utility rooms.
