turned up this morn to check on ufh, when i got there two guys were still fitting it, devi mat 4m2, right ill go and get slc be back in 40 mins ok no probs, when i got back they had gone , i asked customer they finished then and did they test it , he did,nt know , when i went to check onit they had laid out ufh matt but they said it was to big so they coiled whart was left and threw it under the bath . ive told the customer im not happy as i think it will burn out as i cant cover it all . any advice please

I wouldnt touch it until it was fully sorted.

Wow. Shocking.

You can't allow the wires to touch, the heat from ufh needs to disperse through a solid material. If you even held a cable in your hand while on it could get pretty hot, let alone two touching which would build up more heat.

If three or more were touching, and touching metal frames for the bath, it could be a serious accident waiting to happen.

The kit needs to be changed for one that fits. DO NOT TILE IT like it is.

needless to say i did not screed floor, , i will get it sorted thanks

What a bunch of cowboys.... that is why i install the UFH and just get a spark for the final connection.

Same here Dave, if I install it then I know its right, these eejits are chancers that should not be paid nor given the chance to rectify the job. It could have been very serious if left.

There are some heat mats available now that dont need to be 100% covered.

Not sure which ones though, and the manufacturers instructions should ALWAYS be followed.

But you need 100% adhesive bed, so 100% coverage on the heat mat..

Yer i know Dave, but im sure there is a mat now that if you have too much left over, it doesnt have to be covered with anything.

I could of course be talking complete ****e, as i avoid the dam stuff at ALL costs.

You mean just chucked under the bath or summit..?

yer........

nice keep the bath warm ....?

unbeleiveable

i would like to no how they get away with doing this stuff. they should never get any more work but i bet they do

There are no cable manufactures that would advise you to "sling any excess under the bath" They would be sued for negligence in every case that went wrong.

I have recently had a problem with this.

I got a call from a large construction company we constantly work for.

The Snagging manager stated that all of a sudden 9 months after installation, the warmup kit we installed had failed.

Anyway I rang warmup who charged me the delightful fee of £250 to have a look.

It turns out that my tiler had run the 15 sq m kit out as normal, then tiled using Carrara Marble from Mandarin.

The problem arose when he left an area uncovered at the end termination of the cable ( the weakest point )

So basically he dot and dabbed about 4 sq inches under the bath slightly because the end of the cable has a bigger diameter.

I know sometimes these ends are quite tricky sometimes, nut could of easily been solved by cutting a channel in the wedi board.

So, slab was replaced, re grouted & re sealed. 1 lesson learnt.

If you do not want hot spots, follow instructions.


Small simple mistake cost £250 of hard earned cash.


All the best Lee

One of the reasons why I always screed over ufh.
