we had a flash flood in may may and the insurance company had a company come in to retile the kitchen floor ,we had gone away for the weekend while this was being done , on returning home thought let see what the underfloor heating is like ,so turned it on and it tripped the electric straight away , we rangthe company that fitted it and they said it was out own fault for turning it on ,as was only tiles over 2 days before , we believed them so paid ufh to come and fix the fault , doug arrived found one fault took tiles up and was in line with the grout line , fixed it then rechecked and found another 4 faults same again all in line with the grout ,so far 5 wires cut through in 25% of the floor , fixed and rechecked another 3 cables all cut through on grout line this is now on only 40% of the floor , doug was brilliant was not worth taking any more tiles up and the fault was not caused by us turning it on , ufh has supplied us with full report saying who ever tiled the floor has cut through the cables (nothing to do with us) so we are now in talks with the insurance company and the company that fitted it to get it resolved as is 100% the company who fitted the tiles fault for cutting through the cables when grouting , hope to get resolved soon thanks
