Key Features of the 150W Devi Underfloor Heating Mats for Concrete - DTIR-150

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 concrete floors have been created for a range of installations. Installing a Devicomfort DTIR-150 has been made simple as they are ready to roll onto the floor as soon as they come out of the box.

DEVIcomfort underfloor heating mats for concrete are a very high-quality, self-adhesive all-in-one mat with a strong red PVC outer sheath (non UV stable). It has been created specifically for applying to a concrete floor structure.

Every single mat will have 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.

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. Some other manufacturers will only offer product warranties which don't include the replacement of the flooring. This just goes to show DEVI's commitment to the quality of their product. Every heating mat created has been inspected. This will include 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 timber based floors and high output areas such as conservatories and utility rooms.

The service was not good. They could not accept my credit card because they put down the wrong name! Also they have taken the £20 charge for the return of the mat twice!

thanks for your feedback. As far as I can see you unfortunately incorrectly ordered the wrong size mat online and then I understand there was a credit card issue with the product going to a different address? I would of course be happy to discuss this with you in greater detail.
Many thanks.
