Earthing the cable protection

Just curious, but why put the isolator for UFH so high up?? The only downside I can see to capping in the galv sheet is how much PB will have to be ripped out removing it in 20 to 30 years time for a rewire. Someone will be cursing then.

On the safety aspect you are spot on, get a piece of your galv sheet, place on a bit of wood, get your drill, set on hammer action with a masonry bit of course and see how long it takes to get through. You'll be surprised.

Jason,

I had never thought about that side of it

But the channels for the cable are wide and deep 2"x1" and really smooth. I have used a snake(?) to add extra cables. If you got rid of the old cables first you could easily pull a new set through. I smoothed of the cut edges of the sheet so it wouldn't slice the cable if I had to do this.

As for why it's so high...

It isn't, the ceiling is low. The picture is of the old cold room off the side of the kitchen the ceiling is about 2ish mtrs high. Unless you're Sam Fox you'll have no trouble reaching the switch

plus you can use the old cables to pull the new cables through!
