Problem with laying Devimat

[OhPinchy]

I laid my Devimat underfloor heating in my bathroom there a while back but made a mistake as I have about 3 feet of the actual heating cable running up into the stud wall which has the timer on it. All of the (red) heating cable should be under the tiles but too late for that now.

The other side of the stud is still exposed so if there's anything I can do to remedy it from that side I have the option. I haven't been using the Devimat as I want to be sure this isn't a problem first. The manual says the heating cable runs to a max of I think 22.5 degrees celsius, but I reckon it could still be a problem as heat would dissipate quicker into the open air than the tile adhesive.

Any suggestions on what I can do to make it work effectively without paying to heat the air in the stud and also ensuring it's safe? Would ideas like covering the exposed heating cable in tinfoil, or pouring a bed of concrete around it make things better or worse?

Thanks for any help.

Sorry, can't help Pinchy. Maybe some of that radiator reflector foam would work though.Did you find a solution?

Am planning to install Devimat myself in the near future, is it handy to install?

Its handy enough to install alright, just make sure you plan it out well so you're not left with excess cable.

What's radiator reflector foam?

I haven't done it yet, but I'm now planning on tiling over the excess cable internally in the stud wall - the adhesive and tile will dissipate the heat safely just like it does on the floor. It means I'll be paying to heat a small bit in the stud but it's probably the best way out of it now.

What's radiator reflector foam?

Sorry, it's not foam, it's PVC with aluminimum on one side - usually you slip them behind a radiator to avoid heating the wall on which it's mounted. I got one in Woodies. Looks like this:
