    Hi

    We have extremely hard water and I believe the coil in the cylinder must be covered in limescale given it doesn't heat the cylinder and the pipe on the return is just as hot as the flow into the cylinder.


    Would a stainless steel cylinder have this problem or do I need to put a limescale in line filter before the water tank in the attic?


    Is it possible to remove the limescale or is the cylinder ruined?

    If you have an immersion heater in the top of your cylinder?
    Turn off cold supply to cylinder. Drain off some water from the valve to empty the pipe up to attic and a little more from top of cylinder. Turn off the power supply to immersion. Undo the immersion boss (cheap spanner required). Shine torch into cylinder and you can easily see how much scale you have. If it is full of scale may as well replace as you will need to remove it anyway.
    There may not be that much of a temperature difference between inlet and outlet as it will be hot!
    If your taps and shower heads are getting scaled up I would go for a water softener. Use less soap etc.
    Don't waste money on scale inhibitors which don't work.
