Heating element in water tank

[Coldbrook]

Could someone please explain why my water heating elements only last about 2 months. I have tried different boilers, different elements and checked the earth wire and they still blow. Any ideas?

How much water is left in the tank after you have used the water? Is the element still covered

Had a problem last year. 3 elements in as many months. Turned out the tube the temp sensor goes into was badly soldered so allowing water to leak in. Don't know the brand

here is the element after 2 months, i have tried different makes, even different tanks but still no luck, could it be bore hole water?

Looks like a lot of limescale in only 2 months. Has your borehole water system got a water softener incorporated.
Good chance that would help

It's the limescale that's causing the problem. It builds up on element and it cannot get rid of the heat to the water so burns itself out. For a few months that's a lot of scale.

Limescale is your problem, it causes the element to over heat and fail, get a water softener fitted on boiler or re-plumb on to mains water
