Underfloor Heating Comfy Floor South Africa

I am wanting only to alert people and need to consider that under floor heating. I ordered under floor heating from Comfy Floor South Africa and installed Underfloor heating as heating for our ground floor bathroom. What a waste of time and money. Product does not generate enough output to get the floor up to 22 degrees and keep it there, let alone the room. They supp**** me a replacement thermostat of a different model, I wont go back to them to listen to "expert" its my inadequately stupid fingers that are a fault. Instead I will spend the money or so needed to buy a new thermostat from a more reputable company, I cant face dealing with this lot again and receiving more insults. The lesson I take away is not to ignore negative reviews as I did in this case from another customer that had a similar experience of the www.comfyfloor.co.za
