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.

Great product at a great price!

Great service - very knowledgeable staff on the helpline - advised of exactly which item was compatible as a replacement for an obsolete stat, and prices are very competitive too. Also delivery was perfect as arranged. All in all excellent, and will definitely use again.

an easy choice for the floor i needed heated

My original query was answered very quickly and the follow up supply of goods was equally excellent. Great customer service.

Fantastic, thank you for the great review of our service.

Mat does not appear to be as sticky as a previous product

Your service was quick and efficient. My concern was with the DEVI product information and installation information. I have previously fitted a DEVI mat however the installation information was minimal and no explanation given for the pack content. Fortunately I remembered most of the installation steps. The one that I didn't was answered by DEVI customer help. My point is that the product is good but the installation information is poor as is the online information. If DEVI ask you can feed back this information to them.
