Is it possible to extend area of my UFH?

[rbennett]

Hi, My bathroom has just had Devimat underfloor heating installed but the UFH doesn't cover the entire area of the floor - the builder has laid it down and tiled over the top, but the part where there is no heat is exactly where I stand at the sink. What can I do? He never said that there wasn't enough for the whole area, just went ahead and tiled over the top. Is there any way of fixing this? Could he take one tile off and add in some extra UFH to the existing devimat UFH to cover the cold area? I'm really disappointed as the floor is warm everywhere else, just not in the exact spot where I would like it to be. Is the only option to completely redo the entire floor, which would involve new UFH system and new tiles or is there any way to fix the problem and keep most of the floor as it is?? Thanks for your help!

Who supplied the UFH?

Obviously the wrong size mat was used.......and the only option is to redo the whole lot. No way can you could take up the tiles and move matting.....

Without redoing the whole floor your only option is a rug!

As above I'm afraid. The trouble with UFH is that it's a direct heat and it doesn't spread across the tiles very much so can cause cold spots. Once installed there is no way to extend it so the only option would be to put in another mat in the non heated areas, that would involve so much work and expense that you may as well just redo the whole floor.

Hi everyone, thanks for your answers - good to know.

If you 'ping' the UFH when tiling, can't you repair it? Years so i was told by a sparks there was a Warm Up/similar repair kit that cost about £90?
My point being if they're is, you could take up a small area, cut, extend, re - tile.

As I understand it you can run multiple mats from one stat ( Devi ) , so in theory IF you had enough room left to fix the smalllest mat ( 1m² ( 2000mm x 500mm )) it should be possible to remove tiles and add the extra mat.

Would be tricky though and probably just as easy to start again as has been mentioned.

No you couldn't as the different size mats have different ratings. If you cut a mat and made it smaller ie: 10m² to say 4m² it would melt ( I've seen somebody do that believe it or not ) extending would probably have the reverse effect of not enough power going through the mat ? Not a sparks so i don't know about the latter effect.

I didn't make clear i was talking about Warm Up wire. I know you can repair that hence my reasoning for being able to extend if cut.
