Hi paul , i take it , its electric ufh ?

 

[Paul2468]

Hi dave, yes it is the ditra heat system

 

[Dave]

Ok, The Tiles are heating up ok though and its just some warmth is under the units ? ...

@Dave So this I would imagine means that the mat has been laid under the units then?

 

[Paul2468]

No not under units the kitchen was in place before tiling so could only tile to feet of units. So wondered as cable close to an exposed edge heat could be escaping out the side of tile, yes floor is heating up ok, issue is where kickboards are not as warm as rest of floor.

Do you know if there insulation boards under the heating mat?

 

[Paul2468]

No concrete screed

Did u see the cable laid into the matting?
Sounds like it hasn't been taken close enough to the edge.
Insulation boards, in an ideal situation, would be laid on a screed to prevent heat being radiated downward.

 

[Paul2468]

We laid the cable 75mm in from the feet of the units

As @3_fall said, screed is probably heating up and he's is migrating.
I haven't used this heating system but would have thought a insulation board should have been used.
Measure the screed temperature under the units if you can.

 

[Old Mod]

And how far away is the cold spot?
Is that what Schluter specify, 75mm
Personally probably would have taken it closer.

 

[Paul2468]

That is their spec i believe, not as warm where stand

 

[Old Mod]

Unfortunately it seems that it's purely down to installation,
With no real solution.
