Immersion query for plumbers

[cactikid]

Extra tall lagged tank put in years ago when i got solar panels and the odd time needed to boost temp for power shower via switch to heat the element.

Used to be noisy when switching it on but now it is much quieter and wondering if partly worn out.

Single long coil as no bath in house.

What are you asking?
The element won't be noisy even when new.
Power showers use a pump, do you mean the pump is less noisy?

No the heating element in the Immersion was loud like when you stick the kettle on to boil.

Now it is more silent and unsure if it is heating up the water as i need a good lot of hot water as using a rain soaker head and powered pump.
