Hi

I've a problem with my immersion heater. It seams that no matter how
long I leave it on, the water only manages to get to luke warm. I've
changed the stat and it's the same. Many thanks for any help!

Hopefully, you're rotating your stat adjuster Anti-clockwise to result in a
higher water temp? That's how my 2.7kW immersion heater stat was designed!
If you are in a hard-water area, is your cylinder rather full of limescale?

I would now be tempted to measure the resistance of the element.
17-20 Ohms would be about right.
And the resistance to earth!
