Need to be dual flow taps mate

True, that bath tap has trouble written all over it though!!

On top of everything the new immersion heater seems to be turning on every 2 hours with this cylinder. With the old one it would be closer to every 20 hours. Is this normal at all?

Also when it turns on it makes quite a loud hissing noise whereas the old one was a lot more silent.

No, not really. Such tanks should be controlled by a time-switch set up to have the heater on for the minimum period(s) needed to make sure you have hot water available at the times you use it.
