DEVIcomfort 100w/m2 DTIR-100 2.5m2 250W Underfloor Heating Kit

As in section 1 lack of installation information.

View 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.
