my bottom immersion nay heating the water during the night

Right both are 3kv immersions! the top one the Boost supply has 17ohms reading on the live and neutral coming in the immersion and also 17ohms across the element itself however the bottm immersion has 35 ohms in the incoming supply and 35 ohms between the live and neutral through the element! So do we agree that there is something up with the off peak immersion and needs replacing?

Just do what I said in my post ie test on the element and then through the stat you will not have a high limit on the stat

Marvo he is in Scotland we don't do limescale up here the same as we don't do Part P!sh

Lol, I'm in Cape Town so my knowledge of Scottish water is limited, I read somewhere it's the same colour as beer

Not much difference between 17-35 ohms....if the element had gone would suggest a full o/c or a least a higher reading than 35 ohms. if the element had burnt out would suggest a short circuit to earth

Could never understand why we threw money to the electronic plants because they threatened to go to England only problem was the they used a lot of RO water I know because I worked in one because it was easy to filter our soft water. Mind I still chuckle when I see descaler kits in the local diy shed
