DEVIcomfort 150W/m2 DTIR-150 10.0m2 1500W Underfloor Heating Mat

They sold us three zones but only two thermostats. Therefore cannot control heat in one zone. The Devi Matt floor was fitted by an electrician and an experienced carpenter laid the floor. However as I write this the heat only works in 25% of the room. Will likely have to lift the newly laid floor and will be writing to their customer services
